-# abbrev-js
-
-Just like [ruby's Abbrev](http://apidock.com/ruby/Abbrev).
-
-Usage:
-
-    var abbrev = require("abbrev");
-    abbrev("foo", "fool", "folding", "flop");
-    
-    // returns:
-    { fl: 'flop'
-    , flo: 'flop'
-    , flop: 'flop'
-    , fol: 'folding'
-    , fold: 'folding'
-    , foldi: 'folding'
-    , foldin: 'folding'
-    , folding: 'folding'
-    , foo: 'foo'
-    , fool: 'fool'
-    }
-
-This is handy for command-line scripts, or other cases where you want to be able to accept shorthands.

-## Using version 6
-
-[JSON Schema draft-07](http://json-schema.org/latest/json-schema-validation.html) is published.
-
-[Ajv version 6.0.0](https://github.com/epoberezkin/ajv/releases/tag/v6.0.0) that supports draft-07 is released. It may require either migrating your schemas or updating your code (to continue using draft-04 and v5 schemas, draft-06 schemas will be supported without changes).
-
-__Please note__: To use Ajv with draft-06 schemas you need to explicitly add the meta-schema to the validator instance:
-
-```javascript
-ajv.addMetaSchema(require('ajv/lib/refs/json-schema-draft-06.json'));
-```
-
-To use Ajv with draft-04 schemas in addition to explicitly adding meta-schema you also need to use option schemaId:
-
-```javascript
-var ajv = new Ajv({schemaId: 'id'});
-// If you want to use both draft-04 and draft-06/07 schemas:
-// var ajv = new Ajv({schemaId: 'auto'});
-ajv.addMetaSchema(require('ajv/lib/refs/json-schema-draft-04.json'));
-```

-## Performance
-
-Ajv generates code using [doT templates](https://github.com/olado/doT) to turn JSON Schemas into super-fast validation functions that are efficient for v8 optimization.
-
-Currently Ajv is the fastest and the most standard compliant validator according to these benchmarks:
-
-- [json-schema-benchmark](https://github.com/ebdrup/json-schema-benchmark) - 50% faster than the second place
-- [jsck benchmark](https://github.com/pandastrike/jsck#benchmarks) - 20-190% faster
-- [z-schema benchmark](https://rawgit.com/zaggino/z-schema/master/benchmark/results.html)
-- [themis benchmark](https://cdn.rawgit.com/playlyfe/themis/master/benchmark/results.html)

-
-Currently Ajv is the only validator that passes all the tests from [JSON Schema Test Suite](https://github.com/json-schema/JSON-Schema-Test-Suite) (according to [json-schema-benchmark](https://github.com/ebdrup/json-schema-benchmark), apart from the test that requires that `1.0` is not an integer that is impossible to satisfy in JavaScript).
-
-
-## Install
-
-```
-npm install ajv
-```
-
-
-## <a name="usage"></a>Getting started
-
-Try it in the Node.js REPL: https://tonicdev.com/npm/ajv
-
-
-The fastest validation call:
-
-```javascript
-var Ajv = require('ajv');
-var ajv = new Ajv(); // options can be passed, e.g. {allErrors: true}
-var validate = ajv.compile(schema);
-var valid = validate(data);
-if (!valid) console.log(validate.errors);
-```
-
-or with less code
-
-```javascript
-// ...
-var valid = ajv.validate(schema, data);
-if (!valid) console.log(ajv.errors);
-// ...
-```
-
-or
-
-```javascript
-// ...
-var valid = ajv.addSchema(schema, 'mySchema')
-               .validate('mySchema', data);
-if (!valid) console.log(ajv.errorsText());
-// ...
-```
-
-See [API](#api) and [Options](#options) for more details.
-
-Ajv compiles schemas to functions and caches them in all cases (using schema serialized with [fast-json-stable-stringify](https://github.com/epoberezkin/fast-json-stable-stringify) or a custom function as a key), so that the next time the same schema is used (not necessarily the same object instance) it won't be compiled again.
-
-The best performance is achieved when using compiled functions returned by `compile` or `getSchema` methods (there is no additional function call).
-
-__Please note__: every time a validation function or `ajv.validate` are called `errors` property is overwritten. You need to copy `errors` array reference to another variable if you want to use it later (e.g., in the callback). See [Validation errors](#validation-errors)
-
-
-## Using in browser
-
-You can require Ajv directly from the code you browserify - in this case Ajv will be a part of your bundle.
-
-If you need to use Ajv in several bundles you can create a separate UMD bundle using `npm run bundle` script (thanks to [siddo420](https://github.com/siddo420)).
-
-Then you need to load Ajv in the browser:
-```html
-<script src="ajv.min.js"></script>
-```
-
-This bundle can be used with different module systems; it creates global `Ajv` if no module system is found.
-
-The browser bundle is available on [cdnjs](https://cdnjs.com/libraries/ajv).
-
-Ajv is tested with these browsers:
-
-[![Sauce Test Status](https://saucelabs.com/browser-matrix/epoberezkin.svg)](https://saucelabs.com/u/epoberezkin)
-
-__Please note__: some frameworks, e.g. Dojo, may redefine global require in such way that is not compatible with CommonJS module format. In such case Ajv bundle has to be loaded before the framework and then you can use global Ajv (see issue [#234](https://github.com/epoberezkin/ajv/issues/234)).
-
-
-## Command line interface
-
-CLI is available as a separate npm package [ajv-cli](https://github.com/jessedc/ajv-cli). It supports:
-
-- compiling JSON Schemas to test their validity
-- BETA: generating standalone module exporting a validation function to be used without Ajv (using [ajv-pack](https://github.com/epoberezkin/ajv-pack))
-- migrate schemas to draft-07 (using [json-schema-migrate](https://github.com/epoberezkin/json-schema-migrate))
-- validating data file(s) against JSON Schema
-- testing expected validity of data against JSON Schema
-- referenced schemas
-- custom meta-schemas
-- files in JSON and JavaScript format
-- all Ajv options
-- reporting changes in data after validation in [JSON-patch](https://tools.ietf.org/html/rfc6902) format
-
-
-## Validation keywords
-
-Ajv supports all validation keywords from draft-07 of JSON Schema standard:
-
-- [type](https://github.com/epoberezkin/ajv/blob/master/KEYWORDS.md#type)
-- [for numbers](https://github.com/epoberezkin/ajv/blob/master/KEYWORDS.md#keywords-for-numbers) - maximum, minimum, exclusiveMaximum, exclusiveMinimum, multipleOf
-- [for strings](https://github.com/epoberezkin/ajv/blob/master/KEYWORDS.md#keywords-for-strings) - maxLength, minLength, pattern, format
-- [for arrays](https://github.com/epoberezkin/ajv/blob/master/KEYWORDS.md#keywords-for-arrays) - maxItems, minItems, uniqueItems, items, additionalItems, [contains](https://github.com/epoberezkin/ajv/blob/master/KEYWORDS.md#contains)
-- [for objects](https://github.com/epoberezkin/ajv/blob/master/KEYWORDS.md#keywords-for-objects) - maxProperties, minProperties, required, properties, patternProperties, additionalProperties, dependencies, [propertyNames](https://github.com/epoberezkin/ajv/blob/master/KEYWORDS.md#propertynames)
-- [for all types](https://github.com/epoberezkin/ajv/blob/master/KEYWORDS.md#keywords-for-all-types) - enum, [const](https://github.com/epoberezkin/ajv/blob/master/KEYWORDS.md#const)
-- [compound keywords](https://github.com/epoberezkin/ajv/blob/master/KEYWORDS.md#compound-keywords) - not, oneOf, anyOf, allOf, [if/then/else](https://github.com/epoberezkin/ajv/blob/master/KEYWORDS.md#ifthenelse)
-
-With [ajv-keywords](https://github.com/epoberezkin/ajv-keywords) package Ajv also supports validation keywords from [JSON Schema extension proposals](https://github.com/json-schema/json-schema/wiki/v5-Proposals) for JSON Schema standard:
-
-- [patternRequired](https://github.com/epoberezkin/ajv/blob/master/KEYWORDS.md#patternrequired-proposed) - like `required` but with patterns that some property should match.
-- [formatMaximum, formatMinimum, formatExclusiveMaximum, formatExclusiveMinimum](https://github.com/epoberezkin/ajv/blob/master/KEYWORDS.md#formatmaximum--formatminimum-and-exclusiveformatmaximum--exclusiveformatminimum-proposed) - setting limits for date, time, etc.
-
-See [JSON Schema validation keywords](https://github.com/epoberezkin/ajv/blob/master/KEYWORDS.md) for more details.
-
-
-## Annotation keywords
-
-JSON Schema specification defines several annotation keywords that describe schema itself but do not perform any validation.
-
-- `title` and `description`: information about the data represented by that schema
-- `$comment` (NEW in draft-07): information for developers. With option `$comment` Ajv logs or passes the comment string to the user-supplied function. See [Options](#options).
-- `default`: a default value of the data instance, see [Assigning defaults](#assigning-defaults).
-- `examples` (NEW in draft-06): an array of data instances. Ajv does not check the validity of these instances against the schema.
-- `readOnly` and `writeOnly` (NEW in draft-07): marks data-instance as read-only or write-only in relation to the source of the data (database, api, etc.).
-- `contentEncoding`: [RFC 2045](https://tools.ietf.org/html/rfc2045#section-6.1 ), e.g., "base64".
-- `contentMediaType`: [RFC 2046](https://tools.ietf.org/html/rfc2046), e.g., "image/png".
-
-__Please note__:  Ajv does not implement validation of the keywords `examples`, `contentEncoding` and `contentMediaType` but it reserves them. If you want to create a plugin that implements some of them, it should remove these keywords from the instance.
-
-
-## Formats
-
-Ajv implements formats defined by JSON Schema specification and several other formats. It is recommended NOT to use "format" keyword implementations with untrusted data, as they use potentially unsafe regular expressions - see [ReDoS attack](#redos-attack).
-
-__Please note__: if you need to use "format" keyword to validate untrusted data, you MUST assess their suitability and safety for your validation scenarios.
-
-The following formats are implemented for string validation with "format" keyword:
-
-- _date_: full-date according to [RFC3339](http://tools.ietf.org/html/rfc3339#section-5.6).
-- _time_: time with optional time-zone.
-- _date-time_: date-time from the same source (time-zone is mandatory). `date`, `time` and `date-time` validate ranges in `full` mode and only regexp in `fast` mode (see [options](#options)).
-- _uri_: full URI.
-- _uri-reference_: URI reference, including full and relative URIs.
-- _uri-template_: URI template according to [RFC6570](https://tools.ietf.org/html/rfc6570)
-- _url_ (deprecated): [URL record](https://url.spec.whatwg.org/#concept-url).
-- _email_: email address.
-- _hostname_: host name according to [RFC1034](http://tools.ietf.org/html/rfc1034#section-3.5).
-- _ipv4_: IP address v4.
-- _ipv6_: IP address v6.
-- _regex_: tests whether a string is a valid regular expression by passing it to RegExp constructor.
-- _uuid_: Universally Unique IDentifier according to [RFC4122](http://tools.ietf.org/html/rfc4122).
-- _json-pointer_: JSON-pointer according to [RFC6901](https://tools.ietf.org/html/rfc6901).
-- _relative-json-pointer_: relative JSON-pointer according to [this draft](http://tools.ietf.org/html/draft-luff-relative-json-pointer-00).
-
-__Please note__: JSON Schema draft-07 also defines formats `iri`, `iri-reference`, `idn-hostname` and `idn-email` for URLs, hostnames and emails with international characters. Ajv does not implement these formats. If you create Ajv plugin that implements them please make a PR to mention this plugin here.
-
-There are two modes of format validation: `fast` and `full`. This mode affects formats `date`, `time`, `date-time`, `uri`, `uri-reference`, `email`, and `hostname`. See [Options](#options) for details.
-
-You can add additional formats and replace any of the formats above using [addFormat](#api-addformat) method.
-
-The option `unknownFormats` allows changing the default behaviour when an unknown format is encountered. In this case Ajv can either fail schema compilation (default) or ignore it (default in versions before 5.0.0). You also can whitelist specific format(s) to be ignored. See [Options](#options) for details.
-
-You can find regular expressions used for format validation and the sources that were used in [formats.js](https://github.com/epoberezkin/ajv/blob/master/lib/compile/formats.js).
-
-
-## <a name="ref"></a>Combining schemas with $ref
-
-You can structure your validation logic across multiple schema files and have schemas reference each other using `$ref` keyword.
-
-Example:
-
-```javascript
-var schema = {
-  "$id": "http://example.com/schemas/schema.json",
-  "type": "object",
-  "properties": {
-    "foo": { "$ref": "defs.json#/definitions/int" },
-    "bar": { "$ref": "defs.json#/definitions/str" }
-  }
-};
-
-var defsSchema = {
-  "$id": "http://example.com/schemas/defs.json",
-  "definitions": {
-    "int": { "type": "integer" },
-    "str": { "type": "string" }
-  }
-};
-```
-
-Now to compile your schema you can either pass all schemas to Ajv instance:
-
-```javascript
-var ajv = new Ajv({schemas: [schema, defsSchema]});
-var validate = ajv.getSchema('http://example.com/schemas/schema.json');
-```
-
-or use `addSchema` method:
-
-```javascript
-var ajv = new Ajv;
-var validate = ajv.addSchema(defsSchema)
-                  .compile(schema);
-```
-
-See [Options](#options) and [addSchema](#api) method.
-
-__Please note__:
-- `$ref` is resolved as the uri-reference using schema $id as the base URI (see the example).
-- References can be recursive (and mutually recursive) to implement the schemas for different data structures (such as linked lists, trees, graphs, etc.).
-- You don't have to host your schema files at the URIs that you use as schema $id. These URIs are only used to identify the schemas, and according to JSON Schema specification validators should not expect to be able to download the schemas from these URIs.
-- The actual location of the schema file in the file system is not used.
-- You can pass the identifier of the schema as the second parameter of `addSchema` method or as a property name in `schemas` option. This identifier can be used instead of (or in addition to) schema $id.
-- You cannot have the same $id (or the schema identifier) used for more than one schema - the exception will be thrown.
-- You can implement dynamic resolution of the referenced schemas using `compileAsync` method. In this way you can store schemas in any system (files, web, database, etc.) and reference them without explicitly adding to Ajv instance. See [Asynchronous schema compilation](#asynchronous-schema-compilation).
-
-
-## $data reference
-
-With `$data` option you can use values from the validated data as the values for the schema keywords. See [proposal](https://github.com/json-schema/json-schema/wiki/$data-(v5-proposal)) for more information about how it works.
-
-`$data` reference is supported in the keywords: const, enum, format, maximum/minimum, exclusiveMaximum / exclusiveMinimum, maxLength / minLength, maxItems / minItems, maxProperties / minProperties, formatMaximum / formatMinimum, formatExclusiveMaximum / formatExclusiveMinimum, multipleOf, pattern, required, uniqueItems.
-
-The value of "$data" should be a [JSON-pointer](https://tools.ietf.org/html/rfc6901) to the data (the root is always the top level data object, even if the $data reference is inside a referenced subschema) or a [relative JSON-pointer](http://tools.ietf.org/html/draft-luff-relative-json-pointer-00) (it is relative to the current point in data; if the $data reference is inside a referenced subschema it cannot point to the data outside of the root level for this subschema).
-
-Examples.
-
-This schema requires that the value in property `smaller` is less or equal than the value in the property larger:
-
-```javascript
-var ajv = new Ajv({$data: true});
-
-var schema = {
-  "properties": {
-    "smaller": {
-      "type": "number",
-      "maximum": { "$data": "1/larger" }
-    },
-    "larger": { "type": "number" }
-  }
-};
-
-var validData = {
-  smaller: 5,
-  larger: 7
-};
-
-ajv.validate(schema, validData); // true
-```
-
-This schema requires that the properties have the same format as their field names:
-
-```javascript
-var schema = {
-  "additionalProperties": {
-    "type": "string",
-    "format": { "$data": "0#" }
-  }
-};
-
-var validData = {
-  'date-time': '1963-06-19T08:30:06.283185Z',
-  email: 'joe.bloggs@example.com'
-}
-```
-
-`$data` reference is resolved safely - it won't throw even if some property is undefined. If `$data` resolves to `undefined` the validation succeeds (with the exclusion of `const` keyword). If `$data` resolves to incorrect type (e.g. not "number" for maximum keyword) the validation fails.
-
-
-## $merge and $patch keywords
-
-With the package [ajv-merge-patch](https://github.com/epoberezkin/ajv-merge-patch) you can use the keywords `$merge` and `$patch` that allow extending JSON Schemas with patches using formats [JSON Merge Patch (RFC 7396)](https://tools.ietf.org/html/rfc7396) and [JSON Patch (RFC 6902)](https://tools.ietf.org/html/rfc6902).
-
-To add keywords `$merge` and `$patch` to Ajv instance use this code:
-
-```javascript
-require('ajv-merge-patch')(ajv);
-```
-
-Examples.
-
-Using `$merge`:
-
-```json
-{
-  "$merge": {
-    "source": {
-      "type": "object",
-      "properties": { "p": { "type": "string" } },
-      "additionalProperties": false
-    },
-    "with": {
-      "properties": { "q": { "type": "number" } }
-    }
-  }
-}
-```
-
-Using `$patch`:
-
-```json
-{
-  "$patch": {
-    "source": {
-      "type": "object",
-      "properties": { "p": { "type": "string" } },
-      "additionalProperties": false
-    },
-    "with": [
-      { "op": "add", "path": "/properties/q", "value": { "type": "number" } }
-    ]
-  }
-}
-```
-
-The schemas above are equivalent to this schema:
-
-```json
-{
-  "type": "object",
-  "properties": {
-    "p": { "type": "string" },
-    "q": { "type": "number" }
-  },
-  "additionalProperties": false
-}
-```
-
-The properties `source` and `with` in the keywords `$merge` and `$patch` can use absolute or relative `$ref` to point to other schemas previously added to the Ajv instance or to the fragments of the current schema.
-
-See the package [ajv-merge-patch](https://github.com/epoberezkin/ajv-merge-patch) for more information.
-
-
-## Defining custom keywords
-
-The advantages of using custom keywords are:
-
-- allow creating validation scenarios that cannot be expressed using JSON Schema
-- simplify your schemas
-- help bringing a bigger part of the validation logic to your schemas
-- make your schemas more expressive, less verbose and closer to your application domain
-- implement custom data processors that modify your data (`modifying` option MUST be used in keyword definition) and/or create side effects while the data is being validated
-
-If a keyword is used only for side-effects and its validation result is pre-defined, use option `valid: true/false` in keyword definition to simplify both generated code (no error handling in case of `valid: true`) and your keyword functions (no need to return any validation result).
-
-The concerns you have to be aware of when extending JSON Schema standard with custom keywords are the portability and understanding of your schemas. You will have to support these custom keywords on other platforms and to properly document these keywords so that everybody can understand them in your schemas.
-
-You can define custom keywords with [addKeyword](#api-addkeyword) method. Keywords are defined on the `ajv` instance level - new instances will not have previously defined keywords.
-
-Ajv allows defining keywords with:
-- validation function
-- compilation function
-- macro function
-- inline compilation function that should return code (as string) that will be inlined in the currently compiled schema.
-
-Example. `range` and `exclusiveRange` keywords using compiled schema:
-
-```javascript
-ajv.addKeyword('range', {
-  type: 'number',
-  compile: function (sch, parentSchema) {
-    var min = sch[0];
-    var max = sch[1];
-
-    return parentSchema.exclusiveRange === true
-            ? function (data) { return data > min && data < max; }
-            : function (data) { return data >= min && data <= max; }
-  }
-});
-
-var schema = { "range": [2, 4], "exclusiveRange": true };
-var validate = ajv.compile(schema);
-console.log(validate(2.01)); // true
-console.log(validate(3.99)); // true
-console.log(validate(2)); // false
-console.log(validate(4)); // false
-```
-
-Several custom keywords (typeof, instanceof, range and propertyNames) are defined in [ajv-keywords](https://github.com/epoberezkin/ajv-keywords) package - they can be used for your schemas and as a starting point for your own custom keywords.
-
-See [Defining custom keywords](https://github.com/epoberezkin/ajv/blob/master/CUSTOM.md) for more details.
-
-
-## Asynchronous schema compilation
-
-During asynchronous compilation remote references are loaded using supplied function. See `compileAsync` [method](#api-compileAsync) and `loadSchema` [option](#options).
-
-Example:
-
-```javascript
-var ajv = new Ajv({ loadSchema: loadSchema });
-
-ajv.compileAsync(schema).then(function (validate) {
-  var valid = validate(data);
-  // ...
-});
-
-function loadSchema(uri) {
-  return request.json(uri).then(function (res) {
-    if (res.statusCode >= 400)
-      throw new Error('Loading error: ' + res.statusCode);
-    return res.body;
-  });
-}
-```
-
-__Please note__: [Option](#options) `missingRefs` should NOT be set to `"ignore"` or `"fail"` for asynchronous compilation to work.
-
-
-## Asynchronous validation
-
-Example in Node.js REPL: https://tonicdev.com/esp/ajv-asynchronous-validation
-
-You can define custom formats and keywords that perform validation asynchronously by accessing database or some other service. You should add `async: true` in the keyword or format definition (see [addFormat](#api-addformat), [addKeyword](#api-addkeyword) and [Defining custom keywords](#defining-custom-keywords)).
-
-If your schema uses asynchronous formats/keywords or refers to some schema that contains them it should have `"$async": true` keyword so that Ajv can compile it correctly. If asynchronous format/keyword or reference to asynchronous schema is used in the schema without `$async` keyword Ajv will throw an exception during schema compilation.
-
-__Please note__: all asynchronous subschemas that are referenced from the current or other schemas should have `"$async": true` keyword as well, otherwise the schema compilation will fail.
-
-Validation function for an asynchronous custom format/keyword should return a promise that resolves with `true` or `false` (or rejects with `new Ajv.ValidationError(errors)` if you want to return custom errors from the keyword function).
-
-Ajv compiles asynchronous schemas to [es7 async functions](http://tc39.github.io/ecmascript-asyncawait/) that can optionally be transpiled with [nodent](https://github.com/MatAtBread/nodent). Async functions are supported in Node.js 7+ and all modern browsers. You can also supply any other transpiler as a function via `processCode` option. See [Options](#options).
-
-The compiled validation function has `$async: true` property (if the schema is asynchronous), so you can differentiate these functions if you are using both synchronous and asynchronous schemas.
-
-Validation result will be a promise that resolves with validated data or rejects with an exception `Ajv.ValidationError` that contains the array of validation errors in `errors` property.
-
-
-Example:
-
-```javascript
-var ajv = new Ajv;
-// require('ajv-async')(ajv);
-
-ajv.addKeyword('idExists', {
-  async: true,
-  type: 'number',
-  validate: checkIdExists
-});
-
-
-function checkIdExists(schema, data) {
-  return knex(schema.table)
-  .select('id')
-  .where('id', data)
-  .then(function (rows) {
-    return !!rows.length; // true if record is found
-  });
-}
-
-var schema = {
-  "$async": true,
-  "properties": {
-    "userId": {
-      "type": "integer",
-      "idExists": { "table": "users" }
-    },
-    "postId": {
-      "type": "integer",
-      "idExists": { "table": "posts" }
-    }
-  }
-};
-
-var validate = ajv.compile(schema);
-
-validate({ userId: 1, postId: 19 })
-.then(function (data) {
-  console.log('Data is valid', data); // { userId: 1, postId: 19 }
-})
-.catch(function (err) {
-  if (!(err instanceof Ajv.ValidationError)) throw err;
-  // data is invalid
-  console.log('Validation errors:', err.errors);
-});
-```
-
-### Using transpilers with asynchronous validation functions.
-
-[ajv-async](https://github.com/epoberezkin/ajv-async) uses [nodent](https://github.com/MatAtBread/nodent) to transpile async functions. To use another transpiler you should separately install it (or load its bundle in the browser).
-
-
-#### Using nodent
-
-```javascript
-var ajv = new Ajv;
-require('ajv-async')(ajv);
-// in the browser if you want to load ajv-async bundle separately you can:
-// window.ajvAsync(ajv);
-var validate = ajv.compile(schema); // transpiled es7 async function
-validate(data).then(successFunc).catch(errorFunc);
-```
-
-
-#### Using other transpilers
-
-```javascript
-var ajv = new Ajv({ processCode: transpileFunc });
-var validate = ajv.compile(schema); // transpiled es7 async function
-validate(data).then(successFunc).catch(errorFunc);
-```
-
-See [Options](#options).
-
-
-## Security considerations
-
-JSON Schema, if properly used, can replace data sanitisation. It doesn't replace other API security considerations. It also introduces additional security aspects to consider.
-
-
-##### Security contact
-
-To report a security vulnerability, please use the
-[Tidelift security contact](https://tidelift.com/security).
-Tidelift will coordinate the fix and disclosure. Please do NOT report security vulnerabilities via GitHub issues.
-
-
-##### Untrusted schemas
-
-Ajv treats JSON schemas as trusted as your application code. This security model is based on the most common use case, when the schemas are static and bundled together with the application.
-
-If your schemas are received from untrusted sources (or generated from untrusted data) there are several scenarios you need to prevent:
-- compiling schemas can cause stack overflow (if they are too deep)
-- compiling schemas can be slow (e.g. [#557](https://github.com/epoberezkin/ajv/issues/557))
-- validating certain data can be slow
-
-It is difficult to predict all the scenarios, but at the very least it may help to limit the size of untrusted schemas (e.g. limit JSON string length) and also the maximum schema object depth (that can be high for relatively small JSON strings). You also may want to mitigate slow regular expressions in `pattern` and `patternProperties` keywords.
-
-Regardless the measures you take, using untrusted schemas increases security risks.
-
-
-##### Circular references in JavaScript objects
-
-Ajv does not support schemas and validated data that have circular references in objects. See [issue #802](https://github.com/epoberezkin/ajv/issues/802).
-
-An attempt to compile such schemas or validate such data would cause stack overflow (or will not complete in case of asynchronous validation). Depending on the parser you use, untrusted data can lead to circular references.
-
-
-##### Security risks of trusted schemas
-
-Some keywords in JSON Schemas can lead to very slow validation for certain data. These keywords include (but may be not limited to):
-
-- `pattern` and `format` for large strings - in some cases using `maxLength` can help mitigate it, but certain regular expressions can lead to exponential validation time even with relatively short strings (see [ReDoS attack](#redos-attack)).
-- `patternProperties` for large property names - use `propertyNames` to mitigate, but some regular expressions can have exponential evaluation time as well.
-- `uniqueItems` for large non-scalar arrays - use `maxItems` to mitigate
-
-__Please note__: The suggestions above to prevent slow validation would only work if you do NOT use `allErrors: true` in production code (using it would continue validation after validation errors).
-
-You can validate your JSON schemas against [this meta-schema](https://github.com/epoberezkin/ajv/blob/master/lib/refs/json-schema-secure.json) to check that these recommendations are followed:
-
-```javascript
-const isSchemaSecure = ajv.compile(require('ajv/lib/refs/json-schema-secure.json'));
-
-const schema1 = {format: 'email'};
-isSchemaSecure(schema1); // false
-
-const schema2 = {format: 'email', maxLength: MAX_LENGTH};
-isSchemaSecure(schema2); // true
-```
-
-__Please note__: following all these recommendation is not a guarantee that validation of untrusted data is safe - it can still lead to some undesirable results.
-
-
-## ReDoS attack
-
-Certain regular expressions can lead to the exponential evaluation time even with relatively short strings.
-
-Please assess the regular expressions you use in the schemas on their vulnerability to this attack - see [safe-regex](https://github.com/substack/safe-regex), for example.
-
-__Please note__: some formats that Ajv implements use [regular expressions](https://github.com/epoberezkin/ajv/blob/master/lib/compile/formats.js) that can be vulnerable to ReDoS attack, so if you use Ajv to validate data from untrusted sources __it is strongly recommended__ to consider the following:
-
-- making assessment of "format" implementations in Ajv.
-- using `format: 'fast'` option that simplifies some of the regular expressions (although it does not guarantee that they are safe).
-- replacing format implementations provided by Ajv with your own implementations of "format" keyword that either uses different regular expressions or another approach to format validation. Please see [addFormat](#api-addformat) method.
-- disabling format validation by ignoring "format" keyword with option `format: false`
-
-Whatever mitigation you choose, please assume all formats provided by Ajv as potentially unsafe and make your own assessment of their suitability for your validation scenarios.
-
-
-## Filtering data
-
-With [option `removeAdditional`](#options) (added by [andyscott](https://github.com/andyscott)) you can filter data during the validation.
-
-This option modifies original data.
-
-Example:
-
-```javascript
-var ajv = new Ajv({ removeAdditional: true });
-var schema = {
-  "additionalProperties": false,
-  "properties": {
-    "foo": { "type": "number" },
-    "bar": {
-      "additionalProperties": { "type": "number" },
-      "properties": {
-        "baz": { "type": "string" }
-      }
-    }
-  }
-}
-
-var data = {
-  "foo": 0,
-  "additional1": 1, // will be removed; `additionalProperties` == false
-  "bar": {
-    "baz": "abc",
-    "additional2": 2 // will NOT be removed; `additionalProperties` != false
-  },
-}
-
-var validate = ajv.compile(schema);
-
-console.log(validate(data)); // true
-console.log(data); // { "foo": 0, "bar": { "baz": "abc", "additional2": 2 }
-```
-
-If `removeAdditional` option in the example above were `"all"` then both `additional1` and `additional2` properties would have been removed.
-
-If the option were `"failing"` then property `additional1` would have been removed regardless of its value and property `additional2` would have been removed only if its value were failing the schema in the inner `additionalProperties` (so in the example above it would have stayed because it passes the schema, but any non-number would have been removed).
-
-__Please note__: If you use `removeAdditional` option with `additionalProperties` keyword inside `anyOf`/`oneOf` keywords your validation can fail with this schema, for example:
-
-```json
-{
-  "type": "object",
-  "oneOf": [
-    {
-      "properties": {
-        "foo": { "type": "string" }
-      },
-      "required": [ "foo" ],
-      "additionalProperties": false
-    },
-    {
-      "properties": {
-        "bar": { "type": "integer" }
-      },
-      "required": [ "bar" ],
-      "additionalProperties": false
-    }
-  ]
-}
-```
-
-The intention of the schema above is to allow objects with either the string property "foo" or the integer property "bar", but not with both and not with any other properties.
-
-With the option `removeAdditional: true` the validation will pass for the object `{ "foo": "abc"}` but will fail for the object `{"bar": 1}`. It happens because while the first subschema in `oneOf` is validated, the property `bar` is removed because it is an additional property according to the standard (because it is not included in `properties` keyword in the same schema).
-
-While this behaviour is unexpected (issues [#129](https://github.com/epoberezkin/ajv/issues/129), [#134](https://github.com/epoberezkin/ajv/issues/134)), it is correct. To have the expected behaviour (both objects are allowed and additional properties are removed) the schema has to be refactored in this way:
-
-```json
-{
-  "type": "object",
-  "properties": {
-    "foo": { "type": "string" },
-    "bar": { "type": "integer" }
-  },
-  "additionalProperties": false,
-  "oneOf": [
-    { "required": [ "foo" ] },
-    { "required": [ "bar" ] }
-  ]
-}
-```
-
-The schema above is also more efficient - it will compile into a faster function.
-
-
-## Assigning defaults
-
-With [option `useDefaults`](#options) Ajv will assign values from `default` keyword in the schemas of `properties` and `items` (when it is the array of schemas) to the missing properties and items.
-
-With the option value `"empty"` properties and items equal to `null` or `""` (empty string) will be considered missing and assigned defaults.
-
-This option modifies original data.
-
-__Please note__: the default value is inserted in the generated validation code as a literal, so the value inserted in the data will be the deep clone of the default in the schema.
-
-
-Example 1 (`default` in `properties`):
-
-```javascript
-var ajv = new Ajv({ useDefaults: true });
-var schema = {
-  "type": "object",
-  "properties": {
-    "foo": { "type": "number" },
-    "bar": { "type": "string", "default": "baz" }
-  },
-  "required": [ "foo", "bar" ]
-};
-
-var data = { "foo": 1 };
-
-var validate = ajv.compile(schema);
-
-console.log(validate(data)); // true
-console.log(data); // { "foo": 1, "bar": "baz" }
-```
-
-Example 2 (`default` in `items`):
-
-```javascript
-var schema = {
-  "type": "array",
-  "items": [
-    { "type": "number" },
-    { "type": "string", "default": "foo" }
-  ]
-}
-
-var data = [ 1 ];
-
-var validate = ajv.compile(schema);
-
-console.log(validate(data)); // true
-console.log(data); // [ 1, "foo" ]
-```
-
-`default` keywords in other cases are ignored:
-
-- not in `properties` or `items` subschemas
-- in schemas inside `anyOf`, `oneOf` and `not` (see [#42](https://github.com/epoberezkin/ajv/issues/42))
-- in `if` subschema of `switch` keyword
-- in schemas generated by custom macro keywords
-
-The [`strictDefaults` option](#options) customizes Ajv's behavior for the defaults that Ajv ignores (`true` raises an error, and `"log"` outputs a warning).
-
-
-## Coercing data types
-
-When you are validating user inputs all your data properties are usually strings. The option `coerceTypes` allows you to have your data types coerced to the types specified in your schema `type` keywords, both to pass the validation and to use the correctly typed data afterwards.
-
-This option modifies original data.
-
-__Please note__: if you pass a scalar value to the validating function its type will be coerced and it will pass the validation, but the value of the variable you pass won't be updated because scalars are passed by value.
-
-
-Example 1:
-
-```javascript
-var ajv = new Ajv({ coerceTypes: true });
-var schema = {
-  "type": "object",
-  "properties": {
-    "foo": { "type": "number" },
-    "bar": { "type": "boolean" }
-  },
-  "required": [ "foo", "bar" ]
-};
-
-var data = { "foo": "1", "bar": "false" };
-
-var validate = ajv.compile(schema);
-
-console.log(validate(data)); // true
-console.log(data); // { "foo": 1, "bar": false }
-```
-
-Example 2 (array coercions):
-
-```javascript
-var ajv = new Ajv({ coerceTypes: 'array' });
-var schema = {
-  "properties": {
-    "foo": { "type": "array", "items": { "type": "number" } },
-    "bar": { "type": "boolean" }
-  }
-};
-
-var data = { "foo": "1", "bar": ["false"] };
-
-var validate = ajv.compile(schema);
-
-console.log(validate(data)); // true
-console.log(data); // { "foo": [1], "bar": false }
-```
-
-The coercion rules, as you can see from the example, are different from JavaScript both to validate user input as expected and to have the coercion reversible (to correctly validate cases where different types are defined in subschemas of "anyOf" and other compound keywords).
-
-See [Coercion rules](https://github.com/epoberezkin/ajv/blob/master/COERCION.md) for details.
-
-
-## API
-
-##### new Ajv(Object options) -&gt; Object
-
-Create Ajv instance.
-
-
-##### .compile(Object schema) -&gt; Function&lt;Object data&gt;
-
-Generate validating function and cache the compiled schema for future use.
-
-Validating function returns a boolean value. This function has properties `errors` and `schema`. Errors encountered during the last validation are assigned to `errors` property (it is assigned `null` if there was no errors). `schema` property contains the reference to the original schema.
-
-The schema passed to this method will be validated against meta-schema unless `validateSchema` option is false. If schema is invalid, an error will be thrown. See [options](#options).
-
-
-##### <a name="api-compileAsync"></a>.compileAsync(Object schema [, Boolean meta] [, Function callback]) -&gt; Promise
-
-Asynchronous version of `compile` method that loads missing remote schemas using asynchronous function in `options.loadSchema`. This function returns a Promise that resolves to a validation function. An optional callback passed to `compileAsync` will be called with 2 parameters: error (or null) and validating function. The returned promise will reject (and the callback will be called with an error) when:
-
-- missing schema can't be loaded (`loadSchema` returns a Promise that rejects).
-- a schema containing a missing reference is loaded, but the reference cannot be resolved.
-- schema (or some loaded/referenced schema) is invalid.
-
-The function compiles schema and loads the first missing schema (or meta-schema) until all missing schemas are loaded.
-
-You can asynchronously compile meta-schema by passing `true` as the second parameter.
-
-See example in [Asynchronous compilation](#asynchronous-schema-compilation).
-
-
-##### .validate(Object schema|String key|String ref, data) -&gt; Boolean
-
-Validate data using passed schema (it will be compiled and cached).
-
-Instead of the schema you can use the key that was previously passed to `addSchema`, the schema id if it was present in the schema or any previously resolved reference.
-
-Validation errors will be available in the `errors` property of Ajv instance (`null` if there were no errors).
-
-__Please note__: every time this method is called the errors are overwritten so you need to copy them to another variable if you want to use them later.
-
-If the schema is asynchronous (has `$async` keyword on the top level) this method returns a Promise. See [Asynchronous validation](#asynchronous-validation).
-
-
-##### .addSchema(Array&lt;Object&gt;|Object schema [, String key]) -&gt; Ajv
-
-Add schema(s) to validator instance. This method does not compile schemas (but it still validates them). Because of that dependencies can be added in any order and circular dependencies are supported. It also prevents unnecessary compilation of schemas that are containers for other schemas but not used as a whole.
-
-Array of schemas can be passed (schemas should have ids), the second parameter will be ignored.
-
-Key can be passed that can be used to reference the schema and will be used as the schema id if there is no id inside the schema. If the key is not passed, the schema id will be used as the key.
-
-
-Once the schema is added, it (and all the references inside it) can be referenced in other schemas and used to validate data.
-
-Although `addSchema` does not compile schemas, explicit compilation is not required - the schema will be compiled when it is used first time.
-
-By default the schema is validated against meta-schema before it is added, and if the schema does not pass validation the exception is thrown. This behaviour is controlled by `validateSchema` option.
-
-__Please note__: Ajv uses the [method chaining syntax](https://en.wikipedia.org/wiki/Method_chaining) for all methods with the prefix `add*` and `remove*`.
-This allows you to do nice things like the following.
-
-```javascript
-var validate = new Ajv().addSchema(schema).addFormat(name, regex).getSchema(uri);
-```
-
-##### .addMetaSchema(Array&lt;Object&gt;|Object schema [, String key]) -&gt; Ajv
-
-Adds meta schema(s) that can be used to validate other schemas. That function should be used instead of `addSchema` because there may be instance options that would compile a meta schema incorrectly (at the moment it is `removeAdditional` option).
-
-There is no need to explicitly add draft-07 meta schema (http://json-schema.org/draft-07/schema) - it is added by default, unless option `meta` is set to `false`. You only need to use it if you have a changed meta-schema that you want to use to validate your schemas. See `validateSchema`.
-
-
-##### <a name="api-validateschema"></a>.validateSchema(Object schema) -&gt; Boolean
-
-Validates schema. This method should be used to validate schemas rather than `validate` due to the inconsistency of `uri` format in JSON Schema standard.
-
-By default this method is called automatically when the schema is added, so you rarely need to use it directly.
-
-If schema doesn't have `$schema` property, it is validated against draft 6 meta-schema (option `meta` should not be false).
-
-If schema has `$schema` property, then the schema with this id (that should be previously added) is used to validate passed schema.
-
-Errors will be available at `ajv.errors`.
-
-
-##### .getSchema(String key) -&gt; Function&lt;Object data&gt;
-
-Retrieve compiled schema previously added with `addSchema` by the key passed to `addSchema` or by its full reference (id). The returned validating function has `schema` property with the reference to the original schema.
-
-
-##### .removeSchema([Object schema|String key|String ref|RegExp pattern]) -&gt; Ajv
-
-Remove added/cached schema. Even if schema is referenced by other schemas it can be safely removed as dependent schemas have local references.
-
-Schema can be removed using:
-- key passed to `addSchema`
-- it's full reference (id)
-- RegExp that should match schema id or key (meta-schemas won't be removed)
-- actual schema object that will be stable-stringified to remove schema from cache
-
-If no parameter is passed all schemas but meta-schemas will be removed and the cache will be cleared.
-
-
-##### <a name="api-addformat"></a>.addFormat(String name, String|RegExp|Function|Object format) -&gt; Ajv
-
-Add custom format to validate strings or numbers. It can also be used to replace pre-defined formats for Ajv instance.
-
-Strings are converted to RegExp.
-
-Function should return validation result as `true` or `false`.
-
-If object is passed it should have properties `validate`, `compare` and `async`:
-
-- _validate_: a string, RegExp or a function as described above.
-- _compare_: an optional comparison function that accepts two strings and compares them according to the format meaning. This function is used with keywords `formatMaximum`/`formatMinimum` (defined in [ajv-keywords](https://github.com/epoberezkin/ajv-keywords) package). It should return `1` if the first value is bigger than the second value, `-1` if it is smaller and `0` if it is equal.
-- _async_: an optional `true` value if `validate` is an asynchronous function; in this case it should return a promise that resolves with a value `true` or `false`.
-- _type_: an optional type of data that the format applies to. It can be `"string"` (default) or `"number"` (see https://github.com/epoberezkin/ajv/issues/291#issuecomment-259923858). If the type of data is different, the validation will pass.
-
-Custom formats can be also added via `formats` option.
-
-
-##### <a name="api-addkeyword"></a>.addKeyword(String keyword, Object definition) -&gt; Ajv
-
-Add custom validation keyword to Ajv instance.
-
-Keyword should be different from all standard JSON Schema keywords and different from previously defined keywords. There is no way to redefine keywords or to remove keyword definition from the instance.
-
-Keyword must start with a letter, `_` or `$`, and may continue with letters, numbers, `_`, `$`, or `-`.
-It is recommended to use an application-specific prefix for keywords to avoid current and future name collisions.
-
-Example Keywords:
-- `"xyz-example"`: valid, and uses prefix for the xyz project to avoid name collisions.
-- `"example"`: valid, but not recommended as it could collide with future versions of JSON Schema etc.
-- `"3-example"`: invalid as numbers are not allowed to be the first character in a keyword
-
-Keyword definition is an object with the following properties:
-
-- _type_: optional string or array of strings with data type(s) that the keyword applies to. If not present, the keyword will apply to all types.
-- _validate_: validating function
-- _compile_: compiling function
-- _macro_: macro function
-- _inline_: compiling function that returns code (as string)
-- _schema_: an optional `false` value used with "validate" keyword to not pass schema
-- _metaSchema_: an optional meta-schema for keyword schema
-- _dependencies_: an optional list of properties that must be present in the parent schema - it will be checked during schema compilation
-- _modifying_: `true` MUST be passed if keyword modifies data
-- _statements_: `true` can be passed in case inline keyword generates statements (as opposed to expression)
-- _valid_: pass `true`/`false` to pre-define validation result, the result returned from validation function will be ignored. This option cannot be used with macro keywords.
-- _$data_: an optional `true` value to support [$data reference](#data-reference) as the value of custom keyword. The reference will be resolved at validation time. If the keyword has meta-schema it would be extended to allow $data and it will be used to validate the resolved value. Supporting $data reference requires that keyword has validating function (as the only option or in addition to compile, macro or inline function).
-- _async_: an optional `true` value if the validation function is asynchronous (whether it is compiled or passed in _validate_ property); in this case it should return a promise that resolves with a value `true` or `false`. This option is ignored in case of "macro" and "inline" keywords.
-- _errors_: an optional boolean or string `"full"` indicating whether keyword returns errors. If this property is not set Ajv will determine if the errors were set in case of failed validation.
-
-_compile_, _macro_ and _inline_ are mutually exclusive, only one should be used at a time. _validate_ can be used separately or in addition to them to support $data reference.
-
-__Please note__: If the keyword is validating data type that is different from the type(s) in its definition, the validation function will not be called (and expanded macro will not be used), so there is no need to check for data type inside validation function or inside schema returned by macro function (unless you want to enforce a specific type and for some reason do not want to use a separate `type` keyword for that). In the same way as standard keywords work, if the keyword does not apply to the data type being validated, the validation of this keyword will succeed.
-
-See [Defining custom keywords](#defining-custom-keywords) for more details.
-
-
-##### .getKeyword(String keyword) -&gt; Object|Boolean
-
-Returns custom keyword definition, `true` for pre-defined keywords and `false` if the keyword is unknown.
-
-
-##### .removeKeyword(String keyword) -&gt; Ajv
-
-Removes custom or pre-defined keyword so you can redefine them.
-
-While this method can be used to extend pre-defined keywords, it can also be used to completely change their meaning - it may lead to unexpected results.
-
-__Please note__: schemas compiled before the keyword is removed will continue to work without changes. To recompile schemas use `removeSchema` method and compile them again.
-
-
-##### .errorsText([Array&lt;Object&gt; errors [, Object options]]) -&gt; String
-
-Returns the text with all errors in a String.
-
-Options can have properties `separator` (string used to separate errors, ", " by default) and `dataVar` (the variable name that dataPaths are prefixed with, "data" by default).
-
-

-
-##### Validation and reporting options
-
-- _$data_: support [$data references](#data-reference). Draft 6 meta-schema that is added by default will be extended to allow them. If you want to use another meta-schema you need to use $dataMetaSchema method to add support for $data reference. See [API](#api).
-- _allErrors_: check all rules collecting all errors. Default is to return after the first error.
-- _verbose_: include the reference to the part of the schema (`schema` and `parentSchema`) and validated data in errors (false by default).
-- _$comment_ (NEW in Ajv version 6.0): log or pass the value of `$comment` keyword to a function. Option values:
-  - `false` (default): ignore $comment keyword.
-  - `true`: log the keyword value to console.
-  - function: pass the keyword value, its schema path and root schema to the specified function
-- _jsonPointers_: set `dataPath` property of errors using [JSON Pointers](https://tools.ietf.org/html/rfc6901) instead of JavaScript property access notation.
-- _uniqueItems_: validate `uniqueItems` keyword (true by default).
-- _unicode_: calculate correct length of strings with unicode pairs (true by default). Pass `false` to use `.length` of strings that is faster, but gives "incorrect" lengths of strings with unicode pairs - each unicode pair is counted as two characters.
-- _nullable_: support keyword "nullable" from [Open API 3 specification](https://swagger.io/docs/specification/data-models/data-types/).
-- _format_: formats validation mode. Option values:
-  - `"fast"` (default) - simplified and fast validation (see [Formats](#formats) for details of which formats are available and affected by this option).
-  - `"full"` - more restrictive and slow validation. E.g., 25:00:00 and 2015/14/33 will be invalid time and date in 'full' mode but it will be valid in 'fast' mode.
-  - `false` - ignore all format keywords.
-- _formats_: an object with custom formats. Keys and values will be passed to `addFormat` method.
-- _unknownFormats_: handling of unknown formats. Option values:
-  - `true` (default) - if an unknown format is encountered the exception is thrown during schema compilation. If `format` keyword value is [$data reference](#data-reference) and it is unknown the validation will fail.
-  - `[String]` - an array of unknown format names that will be ignored. This option can be used to allow usage of third party schemas with format(s) for which you don't have definitions, but still fail if another unknown format is used. If `format` keyword value is [$data reference](#data-reference) and it is not in this array the validation will fail.
-  - `"ignore"` - to log warning during schema compilation and always pass validation (the default behaviour in versions before 5.0.0). This option is not recommended, as it allows to mistype format name and it won't be validated without any error message. This behaviour is required by JSON Schema specification.
-- _schemas_: an array or object of schemas that will be added to the instance. In case you pass the array the schemas must have IDs in them. When the object is passed the method `addSchema(value, key)` will be called for each schema in this object.
-- _logger_: sets the logging method. Default is the global `console` object that should have methods `log`, `warn` and `error`. Option values:
-  - custom logger - it should have methods `log`, `warn` and `error`. If any of these methods is missing an exception will be thrown.
-  - `false` - logging is disabled.
-
-
-##### Referenced schema options
-
-- _schemaId_: this option defines which keywords are used as schema URI. Option value:
-  - `"$id"` (default) - only use `$id` keyword as schema URI (as specified in JSON Schema draft-06/07), ignore `id` keyword (if it is present a warning will be logged).
-  - `"id"` - only use `id` keyword as schema URI (as specified in JSON Schema draft-04), ignore `$id` keyword (if it is present a warning will be logged).
-  - `"auto"` - use both `$id` and `id` keywords as schema URI. If both are present (in the same schema object) and different the exception will be thrown during schema compilation.
-- _missingRefs_: handling of missing referenced schemas. Option values:
-  - `true` (default) - if the reference cannot be resolved during compilation the exception is thrown. The thrown error has properties `missingRef` (with hash fragment) and `missingSchema` (without it). Both properties are resolved relative to the current base id (usually schema id, unless it was substituted).
-  - `"ignore"` - to log error during compilation and always pass validation.
-  - `"fail"` - to log error and successfully compile schema but fail validation if this rule is checked.
-- _extendRefs_: validation of other keywords when `$ref` is present in the schema. Option values:
-  - `"ignore"` (default) - when `$ref` is used other keywords are ignored (as per [JSON Reference](https://tools.ietf.org/html/draft-pbryan-zyp-json-ref-03#section-3) standard). A warning will be logged during the schema compilation.
-  - `"fail"` (recommended) - if other validation keywords are used together with `$ref` the exception will be thrown when the schema is compiled. This option is recommended to make sure schema has no keywords that are ignored, which can be confusing.
-  - `true` - validate all keywords in the schemas with `$ref` (the default behaviour in versions before 5.0.0).
-- _loadSchema_: asynchronous function that will be used to load remote schemas when `compileAsync` [method](#api-compileAsync) is used and some reference is missing (option `missingRefs` should NOT be 'fail' or 'ignore'). This function should accept remote schema uri as a parameter and return a Promise that resolves to a schema. See example in [Asynchronous compilation](#asynchronous-schema-compilation).
-
-
-##### Options to modify validated data
-
-- _removeAdditional_: remove additional properties - see example in [Filtering data](#filtering-data). This option is not used if schema is added with `addMetaSchema` method. Option values:
-  - `false` (default) - not to remove additional properties
-  - `"all"` - all additional properties are removed, regardless of `additionalProperties` keyword in schema (and no validation is made for them).
-  - `true` - only additional properties with `additionalProperties` keyword equal to `false` are removed.
-  - `"failing"` - additional properties that fail schema validation will be removed (where `additionalProperties` keyword is `false` or schema).
-- _useDefaults_: replace missing or undefined properties and items with the values from corresponding `default` keywords. Default behaviour is to ignore `default` keywords. This option is not used if schema is added with `addMetaSchema` method. See examples in [Assigning defaults](#assigning-defaults). Option values:
-  - `false` (default) - do not use defaults
-  - `true` - insert defaults by value (object literal is used).
-  - `"empty"` - in addition to missing or undefined, use defaults for properties and items that are equal to `null` or `""` (an empty string).
-  - `"shared"` (deprecated) - insert defaults by reference. If the default is an object, it will be shared by all instances of validated data. If you modify the inserted default in the validated data, it will be modified in the schema as well.
-- _coerceTypes_: change data type of data to match `type` keyword. See the example in [Coercing data types](#coercing-data-types) and [coercion rules](https://github.com/epoberezkin/ajv/blob/master/COERCION.md). Option values:
-  - `false` (default) - no type coercion.
-  - `true` - coerce scalar data types.
-  - `"array"` - in addition to coercions between scalar types, coerce scalar data to an array with one element and vice versa (as required by the schema).
-
-
-##### Strict mode options
-
-- _strictDefaults_: report ignored `default` keywords in schemas. Option values:
-  - `false` (default) - ignored defaults are not reported
-  - `true` - if an ignored default is present, throw an error
-  - `"log"` - if an ignored default is present, log warning
-- _strictKeywords_: report unknown keywords in schemas. Option values:
-  - `false` (default) - unknown keywords are not reported
-  - `true` - if an unknown keyword is present, throw an error
-  - `"log"` - if an unknown keyword is present, log warning
-
-
-##### Asynchronous validation options
-
-- _transpile_: Requires [ajv-async](https://github.com/epoberezkin/ajv-async) package. It determines whether Ajv transpiles compiled asynchronous validation function. Option values:
-  - `undefined` (default) - transpile with [nodent](https://github.com/MatAtBread/nodent) if async functions are not supported.
-  - `true` - always transpile with nodent.
-  - `false` - do not transpile; if async functions are not supported an exception will be thrown.
-
-
-##### Advanced options
-
-- _meta_: add [meta-schema](http://json-schema.org/documentation.html) so it can be used by other schemas (true by default). If an object is passed, it will be used as the default meta-schema for schemas that have no `$schema` keyword. This default meta-schema MUST have `$schema` keyword.
-- _validateSchema_: validate added/compiled schemas against meta-schema (true by default). `$schema` property in the schema can be http://json-schema.org/draft-07/schema or absent (draft-07 meta-schema will be used) or can be a reference to the schema previously added with `addMetaSchema` method. Option values:
-  - `true` (default) -  if the validation fails, throw the exception.
-  - `"log"` - if the validation fails, log error.
-  - `false` - skip schema validation.
-- _addUsedSchema_: by default methods `compile` and `validate` add schemas to the instance if they have `$id` (or `id`) property that doesn't start with "#". If `$id` is present and it is not unique the exception will be thrown. Set this option to `false` to skip adding schemas to the instance and the `$id` uniqueness check when these methods are used. This option does not affect `addSchema` method.
-- _inlineRefs_: Affects compilation of referenced schemas. Option values:
-  - `true` (default) - the referenced schemas that don't have refs in them are inlined, regardless of their size - that substantially improves performance at the cost of the bigger size of compiled schema functions.
-  - `false` - to not inline referenced schemas (they will be compiled as separate functions).
-  - integer number - to limit the maximum number of keywords of the schema that will be inlined.
-- _passContext_: pass validation context to custom keyword functions. If this option is `true` and you pass some context to the compiled validation function with `validate.call(context, data)`, the `context` will be available as `this` in your custom keywords. By default `this` is Ajv instance.
-- _loopRequired_: by default `required` keyword is compiled into a single expression (or a sequence of statements in `allErrors` mode). In case of a very large number of properties in this keyword it may result in a very big validation function. Pass integer to set the number of properties above which `required` keyword will be validated in a loop - smaller validation function size but also worse performance.
-- _ownProperties_: by default Ajv iterates over all enumerable object properties; when this option is `true` only own enumerable object properties (i.e. found directly on the object rather than on its prototype) are iterated. Contributed by @mbroadst.
-- _multipleOfPrecision_: by default `multipleOf` keyword is validated by comparing the result of division with parseInt() of that result. It works for dividers that are bigger than 1. For small dividers such as 0.01 the result of the division is usually not integer (even when it should be integer, see issue [#84](https://github.com/epoberezkin/ajv/issues/84)). If you need to use fractional dividers set this option to some positive integer N to have `multipleOf` validated using this formula: `Math.abs(Math.round(division) - division) < 1e-N` (it is slower but allows for float arithmetics deviations).
-- _errorDataPath_ (deprecated): set `dataPath` to point to 'object' (default) or to 'property' when validating keywords `required`, `additionalProperties` and `dependencies`.
-- _messages_: Include human-readable messages in errors. `true` by default. `false` can be passed when custom messages are used (e.g. with [ajv-i18n](https://github.com/epoberezkin/ajv-i18n)).
-- _sourceCode_: add `sourceCode` property to validating function (for debugging; this code can be different from the result of toString call).
-- _processCode_: an optional function to process generated code before it is passed to Function constructor. It can be used to either beautify (the validating function is generated without line-breaks) or to transpile code. Starting from version 5.0.0 this option replaced options:
-  - `beautify` that formatted the generated function using [js-beautify](https://github.com/beautify-web/js-beautify). If you want to beautify the generated code pass `require('js-beautify').js_beautify`.
-  - `transpile` that transpiled asynchronous validation function. You can still use `transpile` option with [ajv-async](https://github.com/epoberezkin/ajv-async) package. See [Asynchronous validation](#asynchronous-validation) for more information.
-- _cache_: an optional instance of cache to store compiled schemas using stable-stringified schema as a key. For example, set-associative cache [sacjs](https://github.com/epoberezkin/sacjs) can be used. If not passed then a simple hash is used which is good enough for the common use case (a limited number of statically defined schemas). Cache should have methods `put(key, value)`, `get(key)`, `del(key)` and `clear()`.
-- _serialize_: an optional function to serialize schema to cache key. Pass `false` to use schema itself as a key (e.g., if WeakMap used as a cache). By default [fast-json-stable-stringify](https://github.com/epoberezkin/fast-json-stable-stringify) is used.
-
-
-## Validation errors
-
-In case of validation failure, Ajv assigns the array of errors to `errors` property of validation function (or to `errors` property of Ajv instance when `validate` or `validateSchema` methods were called). In case of [asynchronous validation](#asynchronous-validation), the returned promise is rejected with exception `Ajv.ValidationError` that has `errors` property.
-
-
-### Error objects
-
-Each error is an object with the following properties:
-
-- _keyword_: validation keyword.
-- _dataPath_: the path to the part of the data that was validated. By default `dataPath` uses JavaScript property access notation (e.g., `".prop[1].subProp"`). When the option `jsonPointers` is true (see [Options](#options)) `dataPath` will be set using JSON pointer standard (e.g., `"/prop/1/subProp"`).
-- _schemaPath_: the path (JSON-pointer as a URI fragment) to the schema of the keyword that failed validation.
-- _params_: the object with the additional information about error that can be used to create custom error messages (e.g., using [ajv-i18n](https://github.com/epoberezkin/ajv-i18n) package). See below for parameters set by all keywords.
-- _message_: the standard error message (can be excluded with option `messages` set to false).
-- _schema_: the schema of the keyword (added with `verbose` option).
-- _parentSchema_: the schema containing the keyword (added with `verbose` option)
-- _data_: the data validated by the keyword (added with `verbose` option).
-
-__Please note__: `propertyNames` keyword schema validation errors have an additional property `propertyName`, `dataPath` points to the object. After schema validation for each property name, if it is invalid an additional error is added with the property `keyword` equal to `"propertyNames"`.
-
-
-### Error parameters
-
-Properties of `params` object in errors depend on the keyword that failed validation.
-
-- `maxItems`, `minItems`, `maxLength`, `minLength`, `maxProperties`, `minProperties` - property `limit` (number, the schema of the keyword).
-- `additionalItems` - property `limit` (the maximum number of allowed items in case when `items` keyword is an array of schemas and `additionalItems` is false).
-- `additionalProperties` - property `additionalProperty` (the property not used in `properties` and `patternProperties` keywords).
-- `dependencies` - properties:
-  - `property` (dependent property),
-  - `missingProperty` (required missing dependency - only the first one is reported currently)
-  - `deps` (required dependencies, comma separated list as a string),
-  - `depsCount` (the number of required dependencies).
-- `format` - property `format` (the schema of the keyword).
-- `maximum`, `minimum` - properties:
-  - `limit` (number, the schema of the keyword),
-  - `exclusive` (boolean, the schema of `exclusiveMaximum` or `exclusiveMinimum`),
-  - `comparison` (string, comparison operation to compare the data to the limit, with the data on the left and the limit on the right; can be "<", "<=", ">", ">=")
-- `multipleOf` - property `multipleOf` (the schema of the keyword)
-- `pattern` - property `pattern` (the schema of the keyword)
-- `required` - property `missingProperty` (required property that is missing).
-- `propertyNames` - property `propertyName` (an invalid property name).
-- `patternRequired` (in ajv-keywords) - property `missingPattern` (required pattern that did not match any property).
-- `type` - property `type` (required type(s), a string, can be a comma-separated list)
-- `uniqueItems` - properties `i` and `j` (indices of duplicate items).
-- `const` - property `allowedValue` pointing to the value (the schema of the keyword).
-- `enum` - property `allowedValues` pointing to the array of values (the schema of the keyword).
-- `$ref` - property `ref` with the referenced schema URI.
-- `oneOf` - property `passingSchemas` (array of indices of passing schemas, null if no schema passes).
-- custom keywords (in case keyword definition doesn't create errors) - property `keyword` (the keyword name).
-
-
-## Plugins
-
-Ajv can be extended with plugins that add custom keywords, formats or functions to process generated code. When such plugin is published as npm package it is recommended that it follows these conventions:
-
-- it exports a function
-- this function accepts ajv instance as the first parameter and returns the same instance to allow chaining
-- this function can accept an optional configuration as the second parameter
-
-If you have published a useful plugin please submit a PR to add it to the next section.

-## Contributing
-
-All validation functions are generated using doT templates in [dot](https://github.com/epoberezkin/ajv/tree/master/lib/dot) folder. Templates are precompiled so doT is not a run-time dependency.
-
-`npm run build` - compiles templates to [dotjs](https://github.com/epoberezkin/ajv/tree/master/lib/dotjs) folder.
-
-`npm run watch` - automatically compiles templates when files in dot folder change

-# amdefine
-
-A module that can be used to implement AMD's define() in Node. This allows you
-to code to the AMD API and have the module work in node programs without
-requiring those other programs to use AMD.
-
-## Usage
-
-**1)** Update your package.json to indicate amdefine as a dependency:
-
-```javascript
-    "dependencies": {
-        "amdefine": ">=0.1.0"
-    }
-```
-
-Then run `npm install` to get amdefine into your project.
-
-**2)** At the top of each module that uses define(), place this code:
-
-```javascript
-if (typeof define !== 'function') { var define = require('amdefine')(module) }
-```
-
-**Only use these snippets** when loading amdefine. If you preserve the basic structure,
-with the braces, it will be stripped out when using the [RequireJS optimizer](#optimizer).
-
-You can add spaces, line breaks and even require amdefine with a local path, but
-keep the rest of the structure to get the stripping behavior.
-
-As you may know, because `if` statements in JavaScript don't have their own scope, the var
-declaration in the above snippet is made whether the `if` expression is truthy or not. If
-RequireJS is loaded then the declaration is superfluous because `define` is already already
-declared in the same scope in RequireJS. Fortunately JavaScript handles multiple `var`
-declarations of the same variable in the same scope gracefully.
-
-If you want to deliver amdefine.js with your code rather than specifying it as a dependency
-with npm, then just download the latest release and refer to it using a relative path:
-
-[Latest Version](https://github.com/jrburke/amdefine/raw/latest/amdefine.js)
-
-### amdefine/intercept
-
-Consider this very experimental.
-
-Instead of pasting the piece of text for the amdefine setup of a `define`
-variable in each module you create or consume, you can use `amdefine/intercept`
-instead. It will automatically insert the above snippet in each .js file loaded
-by Node.
-
-**Warning**: you should only use this if you are creating an application that
-is consuming AMD style defined()'d modules that are distributed via npm and want
-to run that code in Node.
-
-For library code where you are not sure if it will be used by others in Node or
-in the browser, then explicitly depending on amdefine and placing the code
-snippet above is suggested path, instead of using `amdefine/intercept`. The
-intercept module affects all .js files loaded in the Node app, and it is
-inconsiderate to modify global state like that unless you are also controlling
-the top level app.
-
-#### Why distribute AMD-style modules via npm?
-
-npm has a lot of weaknesses for front-end use (installed layout is not great,
-should have better support for the `baseUrl + moduleID + '.js' style of loading,
-single file JS installs), but some people want a JS package manager and are
-willing to live with those constraints. If that is you, but still want to author
-in AMD style modules to get dynamic require([]), better direct source usage and
-powerful loader plugin support in the browser, then this tool can help.
-
-#### amdefine/intercept usage
-
-Just require it in your top level app module (for example index.js, server.js):
-
-```javascript
-require('amdefine/intercept');
-```
-
-The module does not return a value, so no need to assign the result to a local
-variable.
-
-Then just require() code as you normally would with Node's require(). Any .js
-loaded after the intercept require will have the amdefine check injected in
-the .js source as it is loaded. It does not modify the source on disk, just
-prepends some content to the text of the module as it is loaded by Node.
-
-#### How amdefine/intercept works
-
-It overrides the `Module._extensions['.js']` in Node to automatically prepend
-the amdefine snippet above. So, it will affect any .js file loaded by your
-app.
-
-## define() usage
-
-It is best if you use the anonymous forms of define() in your module:
-
-```javascript
-define(function (require) {
-    var dependency = require('dependency');
-});
-```
-
-or
-
-```javascript
-define(['dependency'], function (dependency) {
-
-});
-```
-
-## RequireJS optimizer integration. <a name="optimizer"></name>
-
-Version 1.0.3 of the [RequireJS optimizer](http://requirejs.org/docs/optimization.html)
-will have support for stripping the `if (typeof define !== 'function')` check
-mentioned above, so you can include this snippet for code that runs in the
-browser, but avoid taking the cost of the if() statement once the code is
-optimized for deployment.
-
-## Node 0.4 Support
-
-If you want to support Node 0.4, then add `require` as the second parameter to amdefine:
-
-```javascript
-//Only if you want Node 0.4. If using 0.5 or later, use the above snippet.
-if (typeof define !== 'function') { var define = require('amdefine')(module, require) }
-```
-
-## Limitations
-
-### Synchronous vs Asynchronous
-
-amdefine creates a define() function that is callable by your code. It will
-execute and trace dependencies and call the factory function *synchronously*,
-to keep the behavior in line with Node's synchronous dependency tracing.
-
-The exception: calling AMD's callback-style require() from inside a factory
-function. The require callback is called on process.nextTick():
-
-```javascript
-define(function (require) {
-    require(['a'], function(a) {
-        //'a' is loaded synchronously, but
-        //this callback is called on process.nextTick().
-    });
-});
-```
-
-### Loader Plugins
-
-Loader plugins are supported as long as they call their load() callbacks
-synchronously. So ones that do network requests will not work. However plugins
-like [text](http://requirejs.org/docs/api.html#text) can load text files locally.
-
-The plugin API's `load.fromText()` is **not supported** in amdefine, so this means
-transpiler plugins like the [CoffeeScript loader plugin](https://github.com/jrburke/require-cs)
-will not work. This may be fixable, but it is a bit complex, and I do not have
-enough node-fu to figure it out yet. See the source for amdefine.js if you want
-to get an idea of the issues involved.
-
-## Tests
-
-To run the tests, cd to **tests** and run:
-
-```
-node all.js
-node all-intercept.js
-```

-# ansi-styles [![Build Status](https://travis-ci.org/chalk/ansi-styles.svg?branch=master)](https://travis-ci.org/chalk/ansi-styles)
-
-> [ANSI escape codes](http://en.wikipedia.org/wiki/ANSI_escape_code#Colors_and_Styles) for styling strings in the terminal
-
-You probably want the higher-level [chalk](https://github.com/chalk/chalk) module for styling your strings.
-
-![](screenshot.png)
-
-
-## Install
-
-```
-$ npm install --save ansi-styles
-```
-
-
-## Usage
-
-```js
-var ansi = require('ansi-styles');
-
-console.log(ansi.green.open + 'Hello world!' + ansi.green.close);
-```
-
-
-## API
-
-Each style has an `open` and `close` property.
-
-
-## Styles
-
-### Modifiers
-
-- `reset`
-- `bold`
-- `dim`
-- `italic` *(not widely supported)*
-- `underline`
-- `inverse`
-- `hidden`
-- `strikethrough` *(not widely supported)*
-
-### Colors
-
-- `black`
-- `red`
-- `green`
-- `yellow`
-- `blue`
-- `magenta`
-- `cyan`
-- `white`
-- `gray`
-
-### Background colors
-
-- `bgBlack`
-- `bgRed`
-- `bgGreen`
-- `bgYellow`
-- `bgBlue`
-- `bgMagenta`
-- `bgCyan`
-- `bgWhite`
-
-
-## Advanced usage
-
-By default you get a map of styles, but the styles are also available as groups. They are non-enumerable so they don't show up unless you access them explicitly. This makes it easier to expose only a subset in a higher-level module.
-
-- `ansi.modifiers`
-- `ansi.colors`
-- `ansi.bgColors`
-
-
-###### Example
-
-```js
-console.log(ansi.colors.green.open);
-```

-A ridiculously light-weight function argument validator
-
-```
-var validate = require("aproba")
-
-function myfunc(a, b, c) {
-  // `a` must be a string, `b` a number, `c` a function
-  validate('SNF', arguments) // [a,b,c] is also valid
-}
-
-myfunc('test', 23, function () {}) // ok
-myfunc(123, 23, function () {}) // type error
-myfunc('test', 23) // missing arg error
-myfunc('test', 23, function () {}, true) // too many args error
-
-```
-
-Valid types are:
-
-| type | description
-| :--: | :----------
-| *    | matches any type
-| A    | `Array.isArray` OR an `arguments` object
-| S    | typeof == string
-| N    | typeof == number
-| F    | typeof == function
-| O    | typeof == object and not type A and not type E
-| B    | typeof == boolean
-| E    | `instanceof Error` OR `null` **(special: see below)**
-| Z    | == `null`
-
-Validation failures throw one of three exception types, distinguished by a
-`code` property of `EMISSINGARG`, `EINVALIDTYPE` or `ETOOMANYARGS`.
-
-If you pass in an invalid type then it will throw with a code of
-`EUNKNOWNTYPE`.
-
-If an **error** argument is found and is not null then the remaining
-arguments are optional.  That is, if you say `ESO` then that's like using a
-non-magical `E` in: `E|ESO|ZSO`.
-
-### But I have optional arguments?!
-
-You can provide more than one signature by separating them with pipes `|`.
-If any signature matches the arguments then they'll be considered valid.
-
-So for example, say you wanted to write a signature for
-`fs.createWriteStream`.  The docs for it describe it thusly:
-
-```
-fs.createWriteStream(path[, options])
-```
-
-This would be a signature of `SO|S`.  That is, a string and and object, or
-just a string.
-
-Now, if you read the full `fs` docs, you'll see that actually path can ALSO
-be a buffer.  And options can be a string, that is:
-```
-path <String> | <Buffer>
-options <String> | <Object>
-```
-
-To reproduce this you have to fully enumerate all of the possible
-combinations and that implies a signature of `SO|SS|OO|OS|S|O`.  The
-awkwardness is a feature: It reminds you of the complexity you're adding to
-your API when you do this sort of thing.
-
-
-### Browser support
-
-This has no dependencies and should work in browsers, though you'll have
-noisier stack traces.
-
-### Why this exists
-
-I wanted a very simple argument validator. It needed to do two things:
-
-1. Be more concise and easier to use than assertions
-
-2. Not encourage an infinite bikeshed of DSLs
-
-This is why types are specified by a single character and there's no such
-thing as an optional argument. 
-
-This is not intended to validate user data. This is specifically about
-asserting the interface of your functions.
-
-If you need greater validation, I encourage you to write them by hand or
-look elsewhere.

-Hi, figured we could actually use a changelog now:
-
-## 1.1.5 2018-05-24
-
-* [#92](https://github.com/iarna/are-we-there-yet/pull/92) Fix bug where
-  `finish` would throw errors when including `TrackerStream` objects in
-  `TrackerGroup` collections.  (@brianloveswords)
-
-## 1.1.4 2017-04-21
-
-* Fix typo in package.json
-
-## 1.1.3 2017-04-21
-
-* Improve documentation and limit files included in the distribution.
-
-## 1.1.2 2016-03-15
-
-* Add tracker group cycle detection and tests for it
-
-## 1.1.1 2016-01-29
-
-* Fix a typo in stream completion tracker
-
-## 1.1.0 2016-01-29
-
-* Rewrote completion percent computation to be low impact– no more walking a
-  tree of completion groups every time we need this info.  Previously, with
-  medium sized tree of completion groups, even a relatively modest number of
-  calls to the top level `completed()` method would result in absurd numbers
-  of calls overall as it walked down the tree. We now, instead, keep track as
-  we bubble up changes, so the computation is limited to when data changes and
-  to the depth of that one branch, instead of _every_ node. (Plus, we were already
-  incurring _this_ cost, since we already bubbled out changes.)
-* Moved different tracker types out to their own files.
-* Made tests test for TOO MANY events too.
-* Standarized the source code formatting

-are-we-there-yet
-----------------
-
-Track complex hiearchies of asynchronous task completion statuses.  This is
-intended to give you a way of recording and reporting the progress of the big
-recursive fan-out and gather type workflows that are so common in async.
-
-What you do with this completion data is up to you, but the most common use case is to
-feed it to one of the many progress bar modules.
-
-Most progress bar modules include a rudamentary version of this, but my
-needs were more complex.
-
-Usage
-=====
-
-```javascript
-var TrackerGroup = require("are-we-there-yet").TrackerGroup
-
-var top = new TrackerGroup("program")
-
-var single = top.newItem("one thing", 100)
-single.completeWork(20)
-
-console.log(top.completed()) // 0.2
-
-fs.stat("file", function(er, stat) {
-  if (er) throw er  
-  var stream = top.newStream("file", stat.size)
-  console.log(top.completed()) // now 0.1 as single is 50% of the job and is 20% complete
-                              // and 50% * 20% == 10%
-  fs.createReadStream("file").pipe(stream).on("data", function (chunk) {
-    // do stuff with chunk
-  })
-  top.on("change", function (name) {
-    // called each time a chunk is read from "file"
-    // top.completed() will start at 0.1 and fill up to 0.6 as the file is read
-  })
-})
-```
-
-Shared Methods
-==============
-
-* var completed = tracker.completed()
-
-Implemented in: `Tracker`, `TrackerGroup`, `TrackerStream`
-
-Returns the ratio of completed work to work to be done. Range of 0 to 1.
-
-* tracker.finish()
-
-Implemented in: `Tracker`, `TrackerGroup`
-
-Marks the tracker as completed. With a TrackerGroup this marks all of its
-components as completed.
-
-Marks all of the components of this tracker as finished, which in turn means
-that `tracker.completed()` for this will now be 1.
-
-This will result in one or more `change` events being emitted.
-
-Events
-======
-
-All tracker objects emit `change` events with the following arguments:
-
-```
-function (name, completed, tracker)
-```
-
-`name` is the name of the tracker that originally emitted the event,
-or if it didn't have one, the first containing tracker group that had one.
-
-`completed` is the percent complete (as returned by `tracker.completed()` method).
-
-`tracker` is the tracker object that you are listening for events on.
-
-TrackerGroup
-============
-
-* var tracker = new TrackerGroup(**name**)
-
-  * **name** *(optional)* - The name of this tracker group, used in change
-    notifications if the component updating didn't have a name. Defaults to undefined.
-
-Creates a new empty tracker aggregation group. These are trackers whose
-completion status is determined by the completion status of other trackers.
-
-* tracker.addUnit(**otherTracker**, **weight**)
-
-  * **otherTracker** - Any of the other are-we-there-yet tracker objects
-  * **weight** *(optional)* - The weight to give the tracker, defaults to 1.
-
-Adds the **otherTracker** to this aggregation group. The weight determines
-how long you expect this tracker to take to complete in proportion to other
-units.  So for instance, if you add one tracker with a weight of 1 and
-another with a weight of 2, you're saying the second will take twice as long
-to complete as the first.  As such, the first will account for 33% of the
-completion of this tracker and the second will account for the other 67%.
-
-Returns **otherTracker**.
-
-* var subGroup = tracker.newGroup(**name**, **weight**)
-
-The above is exactly equivalent to:
-
-```javascript
-  var subGroup = tracker.addUnit(new TrackerGroup(name), weight)
-```
-
-* var subItem = tracker.newItem(**name**, **todo**, **weight**)
-
-The above is exactly equivalent to:
-
-```javascript
-  var subItem = tracker.addUnit(new Tracker(name, todo), weight)
-```
-
-* var subStream = tracker.newStream(**name**, **todo**, **weight**)
-
-The above is exactly equivalent to:
-
-```javascript
-  var subStream = tracker.addUnit(new TrackerStream(name, todo), weight)
-```
-
-* console.log( tracker.debug() )
-
-Returns a tree showing the completion of this tracker group and all of its
-children, including recursively entering all of the children.
-
-Tracker
-=======
-
-* var tracker = new Tracker(**name**, **todo**)
-
-  * **name** *(optional)* The name of this counter to report in change
-    events.  Defaults to undefined.
-  * **todo** *(optional)* The amount of work todo (a number). Defaults to 0.
-
-Ordinarily these are constructed as a part of a tracker group (via
-`newItem`).
-
-* var completed = tracker.completed()
-
-Returns the ratio of completed work to work to be done. Range of 0 to 1. If
-total work to be done is 0 then it will return 0.
-
-* tracker.addWork(**todo**)
-
-  * **todo** A number to add to the amount of work to be done.
-
-Increases the amount of work to be done, thus decreasing the completion
-percentage.  Triggers a `change` event.
-
-* tracker.completeWork(**completed**)
-
-  * **completed** A number to add to the work complete
-
-Increase the amount of work complete, thus increasing the completion percentage.
-Will never increase the work completed past the amount of work todo. That is,
-percentages > 100% are not allowed. Triggers a `change` event.
-
-* tracker.finish()
-
-Marks this tracker as finished, tracker.completed() will now be 1. Triggers
-a `change` event.
-
-TrackerStream
-=============
-
-* var tracker = new TrackerStream(**name**, **size**, **options**)
-
-  * **name** *(optional)* The name of this counter to report in change
-    events.  Defaults to undefined.
-  * **size** *(optional)* The number of bytes being sent through this stream.
-  * **options** *(optional)* A hash of stream options
-
-The tracker stream object is a pass through stream that updates an internal
-tracker object each time a block passes through.  It's intended to track
-downloads, file extraction and other related activities. You use it by piping
-your data source into it and then using it as your data source.
-
-If your data has a length attribute then that's used as the amount of work
-completed when the chunk is passed through.  If it does not (eg, object
-streams) then each chunk counts as completing 1 unit of work, so your size
-should be the total number of objects being streamed.
-
-* tracker.addWork(**todo**)
-
-  * **todo** Increase the expected overall size by **todo** bytes.
-
-Increases the amount of work to be done, thus decreasing the completion
-percentage.  Triggers a `change` event.

-### Streams Working Group
-
-The Node.js Streams is jointly governed by a Working Group
-(WG)
-that is responsible for high-level guidance of the project.
-
-The WG has final authority over this project including:
-
-* Technical direction
-* Project governance and process (including this policy)
-* Contribution policy
-* GitHub repository hosting
-* Conduct guidelines
-* Maintaining the list of additional Collaborators
-
-For the current list of WG members, see the project
-[README.md](./README.md#current-project-team-members).
-
-### Collaborators
-
-The readable-stream GitHub repository is
-maintained by the WG and additional Collaborators who are added by the
-WG on an ongoing basis.
-
-Individuals making significant and valuable contributions are made
-Collaborators and given commit-access to the project. These
-individuals are identified by the WG and their addition as
-Collaborators is discussed during the WG meeting.
-
-_Note:_ If you make a significant contribution and are not considered
-for commit-access log an issue or contact a WG member directly and it
-will be brought up in the next WG meeting.
-
-Modifications of the contents of the readable-stream repository are
-made on
-a collaborative basis. Anybody with a GitHub account may propose a
-modification via pull request and it will be considered by the project
-Collaborators. All pull requests must be reviewed and accepted by a
-Collaborator with sufficient expertise who is able to take full
-responsibility for the change. In the case of pull requests proposed
-by an existing Collaborator, an additional Collaborator is required
-for sign-off. Consensus should be sought if additional Collaborators
-participate and there is disagreement around a particular
-modification. See _Consensus Seeking Process_ below for further detail
-on the consensus model used for governance.
-
-Collaborators may opt to elevate significant or controversial
-modifications, or modifications that have not found consensus to the
-WG for discussion by assigning the ***WG-agenda*** tag to a pull
-request or issue. The WG should serve as the final arbiter where
-required.
-
-For the current list of Collaborators, see the project
-[README.md](./README.md#members).
-
-### WG Membership
-
-WG seats are not time-limited.  There is no fixed size of the WG.
-However, the expected target is between 6 and 12, to ensure adequate
-coverage of important areas of expertise, balanced with the ability to
-make decisions efficiently.
-
-There is no specific set of requirements or qualifications for WG
-membership beyond these rules.
-
-The WG may add additional members to the WG by unanimous consensus.
-
-A WG member may be removed from the WG by voluntary resignation, or by
-unanimous consensus of all other WG members.
-
-Changes to WG membership should be posted in the agenda, and may be
-suggested as any other agenda item (see "WG Meetings" below).
-
-If an addition or removal is proposed during a meeting, and the full
-WG is not in attendance to participate, then the addition or removal
-is added to the agenda for the subsequent meeting.  This is to ensure
-that all members are given the opportunity to participate in all
-membership decisions.  If a WG member is unable to attend a meeting
-where a planned membership decision is being made, then their consent
-is assumed.
-
-No more than 1/3 of the WG members may be affiliated with the same
-employer.  If removal or resignation of a WG member, or a change of
-employment by a WG member, creates a situation where more than 1/3 of
-the WG membership shares an employer, then the situation must be
-immediately remedied by the resignation or removal of one or more WG
-members affiliated with the over-represented employer(s).
-
-### WG Meetings
-
-The WG meets occasionally on a Google Hangout On Air. A designated moderator
-approved by the WG runs the meeting. Each meeting should be
-published to YouTube.
-
-Items are added to the WG agenda that are considered contentious or
-are modifications of governance, contribution policy, WG membership,
-or release process.
-
-The intention of the agenda is not to approve or review all patches;
-that should happen continuously on GitHub and be handled by the larger
-group of Collaborators.
-
-Any community member or contributor can ask that something be added to
-the next meeting's agenda by logging a GitHub Issue. Any Collaborator,
-WG member or the moderator can add the item to the agenda by adding
-the ***WG-agenda*** tag to the issue.
-
-Prior to each WG meeting the moderator will share the Agenda with
-members of the WG. WG members can add any items they like to the
-agenda at the beginning of each meeting. The moderator and the WG
-cannot veto or remove items.
-
-The WG may invite persons or representatives from certain projects to
-participate in a non-voting capacity.
-
-The moderator is responsible for summarizing the discussion of each
-agenda item and sends it as a pull request after the meeting.
-
-### Consensus Seeking Process
-
-The WG follows a
-[Consensus
-Seeking](http://en.wikipedia.org/wiki/Consensus-seeking_decision-making)
-decision-making model.
-
-When an agenda item has appeared to reach a consensus the moderator
-will ask "Does anyone object?" as a final call for dissent from the
-consensus.
-
-If an agenda item cannot reach a consensus a WG member can call for
-either a closing vote or a vote to table the issue to the next
-meeting. The call for a vote must be seconded by a majority of the WG
-or else the discussion will continue. Simple majority wins.
-
-Note that changes to WG membership require a majority consensus.  See
-"WG Membership" above.

-***Node-core streams for userland***
-
-This package is a mirror of the Streams2 and Streams3 implementations in
-Node-core.
-
-Full documentation may be found on the [Node.js website](https://nodejs.org/dist/v8.11.1/docs/api/stream.html).
-
-If you want to guarantee a stable streams base, regardless of what version of
-Node you, or the users of your libraries are using, use **readable-stream** *only* and avoid the *"stream"* module in Node-core, for background see [this blogpost](http://r.va.gg/2014/06/why-i-dont-use-nodes-core-stream-module.html).
-
-As of version 2.0.0 **readable-stream** uses semantic versioning.
-
-# Streams Working Group
-
-`readable-stream` is maintained by the Streams Working Group, which
-oversees the development and maintenance of the Streams API within
-Node.js. The responsibilities of the Streams Working Group include:
-
-* Addressing stream issues on the Node.js issue tracker.
-* Authoring and editing stream documentation within the Node.js project.
-* Reviewing changes to stream subclasses within the Node.js project.
-* Redirecting changes to streams from the Node.js project to this
-  project.
-* Assisting in the implementation of stream providers within Node.js.
-* Recommending versions of `readable-stream` to be included in Node.js.
-* Messaging about the future of streams to give the community advance
-  notice of changes.

-## Agenda
-
-Extracted from https://github.com/iojs/readable-stream/labels/wg-agenda prior to meeting.
-
-* adopt a charter [#105](https://github.com/iojs/readable-stream/issues/105)
-* release and versioning strategy [#101](https://github.com/iojs/readable-stream/issues/101)
-* simpler stream creation [#102](https://github.com/iojs/readable-stream/issues/102)
-* proposal: deprecate implicit flowing of streams [#99](https://github.com/iojs/readable-stream/issues/99)
-
-## Minutes
-
-### adopt a charter
-
-* group: +1's all around
-
-### What versioning scheme should be adopted?
-* group: +1’s 3.0.0
-* domenic+group: pulling in patches from other sources where appropriate
-* mikeal: version independently, suggesting versions for io.js
-* mikeal+domenic: work with TC to notify in advance of changes
-simpler stream creation
-
-### streamline creation of streams
-* sam: streamline creation of streams
-* domenic: nice simple solution posted
-  but, we lose the opportunity to change the model
-  may not be backwards incompatible (double check keys)
-
-  **action item:** domenic will check
-
-### remove implicit flowing of streams on(‘data’)
-* add isFlowing / isPaused
-* mikeal: worrying that we’re documenting polyfill methods – confuses users
-* domenic: more reflective API is probably good, with warning labels for users
-* new section for mad scientists (reflective stream access)
-* calvin: name the “third state”
-* mikeal: maybe borrow the name from whatwg?
-* domenic: we’re missing the “third state”
-* consensus: kind of difficult to name the third state
-* mikeal: figure out differences in states / compat
-* mathias: always flow on data – eliminates third state
-  * explore what it breaks
-
-**action items:**
-* ask isaac for ability to list packages by what public io.js APIs they use (esp. Stream)
-* ask rod/build for infrastructure
-* **chris**: explore the “flow on data” approach
-* add isPaused/isFlowing
-* add new docs section
-* move isPaused to that section
-

-// necessarily symmetric or synchronous transformation.  For example,
-// a zlib stream might take multiple plain-text writes(), and then
-// emit a single compressed chunk some time in the future.
-//
-// Here's how this works:
-//
-// The Transform stream has all the aspects of the readable and writable
-// stream classes.  When you write(chunk), that calls _write(chunk,cb)
-// internally, and returns false if there's a lot of pending writes
-// buffered up.  When you call read(), that calls _read(n) until
-// there's enough pending readable data buffered up.
-//
-// In a transform stream, the written data is placed in a buffer.  When
-// _read(n) is called, it transforms the queued up data, calling the
-// buffered _write cb's as it consumes chunks.  If consuming a single
-// written chunk would result in multiple output chunks, then the first
-// outputted bit calls the readcb, and subsequent chunks just go into
-// the read buffer, and will cause it to emit 'readable' if necessary.
-//
-// This way, back-pressure is actually determined by the reading side,
-// since _read has to be called to start processing a new chunk.  However,
-// a pathological inflate type of transform can cause excessive buffering
-// here.  For example, imagine a stream where every byte of input is
-// interpreted as an integer from 0-255, and then results in that many
-// bytes of output.  Writing the 4 bytes {ff,ff,ff,ff} would result in
-// 1kb of data being output.  In this case, you could write a very small
-// amount of input, and end up with a very large amount of output.  In
-// such a pathological inflating mechanism, there'd be no way to tell
-// the system to stop doing the transform.  A single 4MB write could
-// cause the system to run out of memory.
-//
-// However, even in such a pathological case, only a single written chunk
-// would be consumed, and then the rest would wait (un-transformed) until
-// the results of the previous transformed chunk were consumed.

-***Node-core v8.9.4 string_decoder for userland***
-
-
-[![NPM](https://nodei.co/npm/string_decoder.png?downloads=true&downloadRank=true)](https://nodei.co/npm/string_decoder/)
-[![NPM](https://nodei.co/npm-dl/string_decoder.png?&months=6&height=3)](https://nodei.co/npm/string_decoder/)
-
-
-```bash
-npm install --save string_decoder
-```
-
-***Node-core string_decoder for userland***
-
-This package is a mirror of the string_decoder implementation in Node-core.
-
-Full documentation may be found on the [Node.js website](https://nodejs.org/dist/v8.9.4/docs/api/).
-
-As of version 1.0.0 **string_decoder** uses semantic versioning.
-
-## Previous versions
-
-Previous version numbers match the versions found in Node core, e.g. 0.10.24 matches Node 0.10.24, likewise 0.11.10 matches Node 0.11.10.
-
-## Update
-
-The *build/* directory contains a build script that will scrape the source from the [nodejs/node](https://github.com/nodejs/node) repo given a specific Node version.
-
-## Streams Working Group
-
-`string_decoder` is maintained by the Streams Working Group, which
-oversees the development and maintenance of the Streams API within
-Node.js. The responsibilities of the Streams Working Group include:
-
-* Addressing stream issues on the Node.js issue tracker.
-* Authoring and editing stream documentation within the Node.js project.
-* Reviewing changes to stream subclasses within the Node.js project.
-* Redirecting changes to streams from the Node.js project to this
-  project.
-* Assisting in the implementation of stream providers within Node.js.
-* Recommending versions of `readable-stream` to be included in Node.js.
-* Messaging about the future of streams to give the community advance
-  notice of changes.
-
-See [readable-stream](https://github.com/nodejs/readable-stream) for
-more details.

-node-asn1 is a library for encoding and decoding ASN.1 datatypes in pure JS.
-Currently BER encoding is supported; at some point I'll likely have to do DER.
-
-## Usage
-
-Mostly, if you're *actually* needing to read and write ASN.1, you probably don't
-need this readme to explain what and why.  If you have no idea what ASN.1 is,
-see this: ftp://ftp.rsa.com/pub/pkcs/ascii/layman.asc
-
-The source is pretty much self-explanatory, and has read/write methods for the
-common types out there.
-
-### Decoding
-
-The following reads an ASN.1 sequence with a boolean.
-
-    var Ber = require('asn1').Ber;
-
-    var reader = new Ber.Reader(Buffer.from([0x30, 0x03, 0x01, 0x01, 0xff]));
-
-    reader.readSequence();
-    console.log('Sequence len: ' + reader.length);
-    if (reader.peek() === Ber.Boolean)
-      console.log(reader.readBoolean());
-
-### Encoding
-
-The following generates the same payload as above.
-
-    var Ber = require('asn1').Ber;
-
-    var writer = new Ber.Writer();
-
-    writer.startSequence();
-    writer.writeBoolean(true);
-    writer.endSequence();
-
-    console.log(writer.buffer);
-
-## Installation
-
-    npm install asn1
-
-## License
-
-MIT.
-
-## Bugs
-
-See <https://github.com/joyent/node-asn1/issues>.

-
-## 1.0.0
-
-- *BREAKING* assert.number (and derivatives) now accept Infinity as valid input
-- Add assert.finite check.  Previous assert.number callers should use this if
-  they expect Infinity inputs to throw.
-
-## 0.2.0
-
-- Fix `assert.object(null)` so it throws
-- Fix optional/arrayOf exports for non-type-of asserts
-- Add optiona/arrayOf exports for Stream/Date/Regex/uuid
-- Add basic unit test coverage

-# assert-plus
-
-This library is a super small wrapper over node's assert module that has two
-things: (1) the ability to disable assertions with the environment variable
-NODE\_NDEBUG, and (2) some API wrappers for argument testing.  Like
-`assert.string(myArg, 'myArg')`.  As a simple example, most of my code looks
-like this:
-
-```javascript
-    var assert = require('assert-plus');
-
-    function fooAccount(options, callback) {
-        assert.object(options, 'options');
-        assert.number(options.id, 'options.id');
-        assert.bool(options.isManager, 'options.isManager');
-        assert.string(options.name, 'options.name');
-        assert.arrayOfString(options.email, 'options.email');
-        assert.func(callback, 'callback');
-
-        // Do stuff
-        callback(null, {});
-    }
-```
-
-# API
-
-All methods that *aren't* part of node's core assert API are simply assumed to
-take an argument, and then a string 'name' that's not a message; `AssertionError`
-will be thrown if the assertion fails with a message like:
-
-    AssertionError: foo (string) is required
-    at test (/home/mark/work/foo/foo.js:3:9)
-    at Object.<anonymous> (/home/mark/work/foo/foo.js:15:1)
-    at Module._compile (module.js:446:26)
-    at Object..js (module.js:464:10)
-    at Module.load (module.js:353:31)
-    at Function._load (module.js:311:12)
-    at Array.0 (module.js:484:10)
-    at EventEmitter._tickCallback (node.js:190:38)
-
-from:
-
-```javascript
-    function test(foo) {
-        assert.string(foo, 'foo');
-    }
-```
-
-There you go.  You can check that arrays are of a homogeneous type with `Arrayof$Type`:
-
-```javascript
-    function test(foo) {
-        assert.arrayOfString(foo, 'foo');
-    }
-```
-
-You can assert IFF an argument is not `undefined` (i.e., an optional arg):
-
-```javascript
-    assert.optionalString(foo, 'foo');
-```
-
-Lastly, you can opt-out of assertion checking altogether by setting the
-environment variable `NODE_NDEBUG=1`.  This is pseudo-useful if you have
-lots of assertions, and don't want to pay `typeof ()` taxes to v8 in
-production.  Be advised:  The standard functions re-exported from `assert` are
-also disabled in assert-plus if NDEBUG is specified.  Using them directly from
-the `assert` module avoids this behavior.
-
-The complete list of APIs is:
-
-* assert.array
-* assert.bool
-* assert.buffer
-* assert.func
-* assert.number
-* assert.finite
-* assert.object
-* assert.string
-* assert.stream

-* assert.regexp
-* assert.uuid
-* assert.arrayOfArray
-* assert.arrayOfBool
-* assert.arrayOfBuffer
-* assert.arrayOfFunc
-* assert.arrayOfNumber
-* assert.arrayOfFinite
-* assert.arrayOfObject
-* assert.arrayOfString
-* assert.arrayOfStream
-* assert.arrayOfDate
-* assert.arrayOfRegexp
-* assert.arrayOfUuid
-* assert.optionalArray
-* assert.optionalBool
-* assert.optionalBuffer
-* assert.optionalFunc
-* assert.optionalNumber
-* assert.optionalFinite
-* assert.optionalObject
-* assert.optionalString
-* assert.optionalStream
-* assert.optionalDate
-* assert.optionalRegexp

-# JavaScript Sync/Async forEach
-
-An optionally-asynchronous forEach with an interesting interface.
-
-## Getting Started
-
-This code should work just fine in Node.js:
-
-First, install the module with: `npm install async-foreach`
-
-```javascript
-var forEach = require('async-foreach').forEach;
-forEach(["a", "b", "c"], function(item, index, arr) {
-  console.log("each", item, index, arr);
-});
-// logs:
-// each a 0 ["a", "b", "c"]
-// each b 1 ["a", "b", "c"]
-// each c 2 ["a", "b", "c"]
-```
-
-Or in the browser:
-
-```html
-<script src="dist/ba-foreach.min.js"></script>
-<script>
-forEach(["a", "b", "c"], function(item, index, arr) {
-  console.log("each", item, index, arr);
-});
-// logs:
-// each a 0 ["a", "b", "c"]
-// each b 1 ["a", "b", "c"]
-// each c 2 ["a", "b", "c"]
-</script>
-```
-
-In the browser, you can attach the forEach method to any object.
-
-```html
-<script>
-this.exports = Bocoup.utils;
-</script>
-<script src="dist/ba-foreach.min.js"></script>
-<script>
-Bocoup.utils.forEach(["a", "b", "c"], function(item, index, arr) {
-  console.log("each", item, index, arr);
-});
-// logs:
-// each a 0 ["a", "b", "c"]
-// each b 1 ["a", "b", "c"]
-// each c 2 ["a", "b", "c"]
-</script>
-```
-
-## The General Idea (Why I thought this was worth sharing)
-
-The idea is to allow the callback to decide _at runtime_ whether the loop will be synchronous or asynchronous. By using `this` in a creative way (in situations where that value isn't already spoken for), an entire control API can be offered without over-complicating function signatures.
-
-```javascript
-forEach(arr, function(item, index) {
-  // Synchronous.
-});
-
-forEach(arr, function(item, index) {
-  // Only when `this.async` is called does iteration becomes asynchronous. The
-  // loop won't be continued until the `done` function is executed.
-  var done = this.async();
-  // Continue in one second.
-  setTimeout(done, 1000);
-});
-
-forEach(arr, function(item, index) {
-  // Break out of synchronous iteration early by returning false.
-  return index !== 1;
-});
-
-forEach(arr, function(item, index) {
-  // Break out of asynchronous iteration early...
-  var done = this.async();
-  // ...by passing false to the done function.
-  setTimeout(function() {
-    done(index !== 1);
-  });
-});
-```
-
-## Examples
-See the unit tests for more examples.
-
-```javascript
-// Generic "done" callback.
-function allDone(notAborted, arr) {
-  console.log("done", notAborted, arr);
-}
-
-// Synchronous.
-forEach(["a", "b", "c"], function(item, index, arr) {
-  console.log("each", item, index, arr);
-}, allDone);
-// logs:
-// each a 0 ["a", "b", "c"]
-// each b 1 ["a", "b", "c"]
-// each c 2 ["a", "b", "c"]
-// done true ["a", "b", "c"]
-
-// Synchronous with early abort.
-forEach(["a", "b", "c"], function(item, index, arr) {
-  console.log("each", item, index, arr);
-  if (item === "b") { return false; }
-}, allDone);
-// logs:
-// each a 0 ["a", "b", "c"]
-// each b 1 ["a", "b", "c"]
-// done false ["a", "b", "c"]
-
-// Asynchronous.
-forEach(["a", "b", "c"], function(item, index, arr) {
-  console.log("each", item, index, arr);
-  var done = this.async();
-  setTimeout(function() {
-    done();
-  }, 500);
-}, allDone);
-// logs:
-// each a 0 ["a", "b", "c"]
-// each b 1 ["a", "b", "c"]
-// each c 2 ["a", "b", "c"]
-// done true ["a", "b", "c"]
-
-// Asynchronous with early abort.
-forEach(["a", "b", "c"], function(item, index, arr) {
-  console.log("each", item, index, arr);
-  var done = this.async();
-  setTimeout(function() {
-    done(item !== "b");
-  }, 500);
-}, allDone);
-// logs:
-// each a 0 ["a", "b", "c"]
-// each b 1 ["a", "b", "c"]
-// done false ["a", "b", "c"]
-
-// Not actually asynchronous.
-forEach(["a", "b", "c"], function(item, index, arr) {
-  console.log("each", item, index, arr);
-  var done = this.async()
-  done();
-}, allDone);
-// logs:
-// each a 0 ["a", "b", "c"]
-// each b 1 ["a", "b", "c"]
-// each c 2 ["a", "b", "c"]
-// done true ["a", "b", "c"]
-
-// Not actually asynchronous with early abort.
-forEach(["a", "b", "c"], function(item, index, arr) {
-  console.log("each", item, index, arr);
-  var done = this.async();
-  done(item !== "b");
-}, allDone);
-// logs:
-// each a 0 ["a", "b", "c"]
-// each b 1 ["a", "b", "c"]
-// done false ["a", "b", "c"]
-```
-
-## Contributing
-In lieu of a formal styleguide, take care to maintain the existing coding style. Add unit tests for any new or changed functionality. Lint and test your code using [grunt](https://github.com/cowboy/grunt).
-
-_Also, please don't edit files in the "dist" subdirectory as they are generated via grunt. You'll find source code in the "lib" subdirectory!_

-  "readme": "# JavaScript Sync/Async forEach\n\nAn optionally-asynchronous forEach with an interesting interface.\n\n## Getting Started\n\nThis code should work just fine in Node.js:\n\nFirst, install the module with: `npm install async-foreach`\n\n```javascript\nvar forEach = require('async-foreach').forEach;\nforEach([\"a\", \"b\", \"c\"], function(item, index, arr) {\n  console.log(\"each\", item, index, arr);\n});\n// logs:\n// each a 0 [\"a\", \"b\", \"c\"]\n// each b 1 [\"a\", \"b\", \"c\"]\n// each c 2 [\"a\", \"b\", \"c\"]\n```\n\nOr in the browser:\n\n```html\n<script src=\"dist/ba-foreach.min.js\"></script>\n<script>\nforEach([\"a\", \"b\", \"c\"], function(item, index, arr) {\n  console.log(\"each\", item, index, arr);\n});\n// logs:\n// each a 0 [\"a\", \"b\", \"c\"]\n// each b 1 [\"a\", \"b\", \"c\"]\n// each c 2 [\"a\", \"b\", \"c\"]\n</script>\n```\n\nIn the browser, you can attach the forEach method to any object.\n\n```html\n<script>\nthis.exports = Bocoup.utils;\n</script>\n<script src=\"dist/ba-foreach.min.js\"></script>\n<script>\nBocoup.utils.forEach([\"a\", \"b\", \"c\"], function(item, index, arr) {\n  console.log(\"each\", item, index, arr);\n});\n// logs:\n// each a 0 [\"a\", \"b\", \"c\"]\n// each b 1 [\"a\", \"b\", \"c\"]\n// each c 2 [\"a\", \"b\", \"c\"]\n</script>\n```\n\n## The General Idea (Why I thought this was worth sharing)\n\nThe idea is to allow the callback to decide _at runtime_ whether the loop will be synchronous or asynchronous. By using `this` in a creative way (in situations where that value isn't already spoken for), an entire control API can be offered without over-complicating function signatures.\n\n```javascript\nforEach(arr, function(item, index) {\n  // Synchronous.\n});\n\nforEach(arr, function(item, index) {\n  // Only when `this.async` is called does iteration becomes asynchronous. The\n  // loop won't be continued until the `done` function is executed.\n  var done = this.async();\n  // Continue in one second.\n  setTimeout(done, 1000);\n});\n\nforEach(arr, function(item, index) {\n  // Break out of synchronous iteration early by returning false.\n  return index !== 1;\n});\n\nforEach(arr, function(item, index) {\n  // Break out of asynchronous iteration early...\n  var done = this.async();\n  // ...by passing false to the done function.\n  setTimeout(function() {\n    done(index !== 1);\n  });\n});\n```\n\n## Examples\nSee the unit tests for more examples.\n\n```javascript\n// Generic \"done\" callback.\nfunction allDone(notAborted, arr) {\n  console.log(\"done\", notAborted, arr);\n}\n\n// Synchronous.\nforEach([\"a\", \"b\", \"c\"], function(item, index, arr) {\n  console.log(\"each\", item, index, arr);\n}, allDone);\n// logs:\n// each a 0 [\"a\", \"b\", \"c\"]\n// each b 1 [\"a\", \"b\", \"c\"]\n// each c 2 [\"a\", \"b\", \"c\"]\n// done true [\"a\", \"b\", \"c\"]\n\n// Synchronous with early abort.\nforEach([\"a\", \"b\", \"c\"], function(item, index, arr) {\n  console.log(\"each\", item, index, arr);\n  if (item === \"b\") { return false; }\n}, allDone);\n// logs:\n// each a 0 [\"a\", \"b\", \"c\"]\n// each b 1 [\"a\", \"b\", \"c\"]\n// done false [\"a\", \"b\", \"c\"]\n\n// Asynchronous.\nforEach([\"a\", \"b\", \"c\"], function(item, index, arr) {\n  console.log(\"each\", item, index, arr);\n  var done = this.async();\n  setTimeout(function() {\n    done();\n  }, 500);\n}, allDone);\n// logs:\n// each a 0 [\"a\", \"b\", \"c\"]\n// each b 1 [\"a\", \"b\", \"c\"]\n// each c 2 [\"a\", \"b\", \"c\"]\n// done true [\"a\", \"b\", \"c\"]\n\n// Asynchronous with early abort.\nforEach([\"a\", \"b\", \"c\"], function(item, index, arr) {\n  console.log(\"each\", item, index, arr);\n  var done = this.async();\n  setTimeout(function() {\n    done(item !== \"b\");\n  }, 500);\n}, allDone);\n// logs:\n// each a 0 [\"a\", \"b\", \"c\"]\n// each b 1 [\"a\", \"b\", \"c\"]\n// done false [\"a\", \"b\", \"c\"]\n\n// Not actually asynchronous.\nforEach([\"a\", \"b\", \"c\"], function(item, index, arr) {\n  console.log(\"each\", item, index, arr);\n  var done = this.async()\n  done();\n}, allDone);\n// logs:\n// each a 0 [\"a\", \"b\", \"c\"]\n// each b 1 [\"a\", \"b\", \"c\"]\n// each c 2 [\"a\", \"b\", \"c\"]\n// done true [\"a\", \"b\", \"c\"]\n\n// Not actually asynchronous with early abort.\nforEach([\"a\", \"b\", \"c\"], function(item, index, arr) {\n  console.log(\"each\", item, index, arr);\n  var done = this.async();\n  done(item !== \"b\");\n}, allDone);\n// logs:\n// each a 0 [\"a\", \"b\", \"c\"]\n// each b 1 [\"a\", \"b\", \"c\"]\n// done false [\"a\", \"b\", \"c\"]\n```\n\n## Contributing\nIn lieu of a formal styleguide, take care to maintain the existing coding style. Add unit tests for any new or changed functionality. Lint and test your code using [grunt](https://github.com/cowboy/grunt).\n\n_Also, please don't edit files in the \"dist\" subdirectory as they are generated via grunt. You'll find source code in the \"lib\" subdirectory!_\n\n## Release History\n\n04/29/2013\nv0.1.3\nRemoved hard Node.js version dependency.\n\n11/17/2011\nv0.1.2\nAdding sparse array support.\nInvalid length properties are now sanitized.\nThis closes issue #1 (like a boss).\n\n11/11/2011\nv0.1.1\nRefactored code to be much simpler. Yay for unit tests!\n\n11/11/2011\nv0.1.0\nInitial Release.\n\n## License\nCopyright (c) 2012 \"Cowboy\" Ben Alman  \nLicensed under the MIT license.  \n<http://benalman.com/about/license/>\n",

-AsyncKit provides harness for `parallel` and `serial` iterators over list of items represented by arrays or objects.
-Optionally it accepts abort function (should be synchronously return by iterator for each item), and terminates left over jobs upon an error event. For specific iteration order built-in (`ascending` and `descending`) and custom sort helpers also supported, via `asynckit.serialOrdered` method.
-
-It ensures async operations to keep behavior more stable and prevent `Maximum call stack size exceeded` errors, from sync iterators.

-## Install
-
-```sh
-$ npm install --save asynckit
-```
-
-## Examples
-
-### Parallel Jobs
-
-Runs iterator over provided array in parallel. Stores output in the `result` array,
-on the matching positions. In unlikely event of an error from one of the jobs,
-will terminate rest of the active jobs (if abort function is provided)
-and return error along with salvaged data to the main callback function.
-
-#### Input Array
-
-```javascript
-var parallel = require('asynckit').parallel
-  , assert   = require('assert')
-  ;
-
-var source         = [ 1, 1, 4, 16, 64, 32, 8, 2 ]
-  , expectedResult = [ 2, 2, 8, 32, 128, 64, 16, 4 ]
-  , expectedTarget = [ 1, 1, 2, 4, 8, 16, 32, 64 ]
-  , target         = []
-  ;
-
-parallel(source, asyncJob, function(err, result)
-{
-  assert.deepEqual(result, expectedResult);
-  assert.deepEqual(target, expectedTarget);
-});
-
-// async job accepts one element from the array
-// and a callback function
-function asyncJob(item, cb)
-{
-  // different delays (in ms) per item
-  var delay = item * 25;
-
-  // pretend different jobs take different time to finish
-  // and not in consequential order
-  var timeoutId = setTimeout(function() {
-    target.push(item);
-    cb(null, item * 2);
-  }, delay);
-
-  // allow to cancel "leftover" jobs upon error
-  // return function, invoking of which will abort this job
-  return clearTimeout.bind(null, timeoutId);
-}
-```
-
-More examples could be found in [test/test-parallel-array.js](test/test-parallel-array.js).
-
-#### Input Object
-
-Also it supports named jobs, listed via object.
-
-```javascript
-var parallel = require('asynckit/parallel')
-  , assert   = require('assert')
-  ;
-
-var source         = { first: 1, one: 1, four: 4, sixteen: 16, sixtyFour: 64, thirtyTwo: 32, eight: 8, two: 2 }
-  , expectedResult = { first: 2, one: 2, four: 8, sixteen: 32, sixtyFour: 128, thirtyTwo: 64, eight: 16, two: 4 }
-  , expectedTarget = [ 1, 1, 2, 4, 8, 16, 32, 64 ]
-  , expectedKeys   = [ 'first', 'one', 'two', 'four', 'eight', 'sixteen', 'thirtyTwo', 'sixtyFour' ]
-  , target         = []
-  , keys           = []
-  ;
-
-parallel(source, asyncJob, function(err, result)
-{
-  assert.deepEqual(result, expectedResult);
-  assert.deepEqual(target, expectedTarget);
-  assert.deepEqual(keys, expectedKeys);
-});
-
-// supports full value, key, callback (shortcut) interface
-function asyncJob(item, key, cb)
-{
-  // different delays (in ms) per item
-  var delay = item * 25;
-
-  // pretend different jobs take different time to finish
-  // and not in consequential order
-  var timeoutId = setTimeout(function() {
-    keys.push(key);
-    target.push(item);
-    cb(null, item * 2);
-  }, delay);
-
-  // allow to cancel "leftover" jobs upon error
-  // return function, invoking of which will abort this job
-  return clearTimeout.bind(null, timeoutId);
-}
-```
-
-More examples could be found in [test/test-parallel-object.js](test/test-parallel-object.js).
-
-### Serial Jobs
-
-Runs iterator over provided array sequentially. Stores output in the `result` array,
-on the matching positions. In unlikely event of an error from one of the jobs,
-will not proceed to the rest of the items in the list
-and return error along with salvaged data to the main callback function.
-
-#### Input Array
-
-```javascript
-var serial = require('asynckit/serial')
-  , assert = require('assert')
-  ;
-
-var source         = [ 1, 1, 4, 16, 64, 32, 8, 2 ]
-  , expectedResult = [ 2, 2, 8, 32, 128, 64, 16, 4 ]
-  , expectedTarget = [ 0, 1, 2, 3, 4, 5, 6, 7 ]
-  , target         = []
-  ;
-
-serial(source, asyncJob, function(err, result)
-{
-  assert.deepEqual(result, expectedResult);
-  assert.deepEqual(target, expectedTarget);
-});
-
-// extended interface (item, key, callback)
-// also supported for arrays
-function asyncJob(item, key, cb)
-{
-  target.push(key);
-
-  // it will be automatically made async
-  // even it iterator "returns" in the same event loop
-  cb(null, item * 2);
-}
-```
-
-More examples could be found in [test/test-serial-array.js](test/test-serial-array.js).
-
-#### Input Object
-
-Also it supports named jobs, listed via object.
-
-```javascript

-  , assert = require('assert')

-
-var source         = [ 1, 1, 4, 16, 64, 32, 8, 2 ]

-  , expectedResult = { first: 2, one: 2, four: 8, sixteen: 32, sixtyFour: 128, thirtyTwo: 64, eight: 16, two: 4 }
-  , expectedTarget = [ 1, 1, 4, 16, 64, 32, 8, 2 ]
-  , target         = []
-  ;
-
-
-serial(source, asyncJob, function(err, result)
-{
-  assert.deepEqual(result, expectedResult);
-  assert.deepEqual(target, expectedTarget);
-});
-
-// shortcut interface (item, callback)
-// works for object as well as for the arrays
-function asyncJob(item, cb)
-{
-  target.push(item);
-
-  // it will be automatically made async
-  // even it iterator "returns" in the same event loop
-  cb(null, item * 2);
-}
-```
-
-More examples could be found in [test/test-serial-object.js](test/test-serial-object.js).
-
-_Note: Since _object_ is an _unordered_ collection of properties,
-it may produce unexpected results with sequential iterations.
-Whenever order of the jobs' execution is important please use `serialOrdered` method._
-
-### Ordered Serial Iterations
-
-TBD
-
-For example [compare-property](compare-property) package.
-
-### Streaming interface
-
-TBD

-[![Build Status](https://secure.travis-ci.org/mhart/aws4.png?branch=master)](http://travis-ci.org/mhart/aws4)
-
-A small utility to sign vanilla Node.js http(s) request options using Amazon's
-[AWS Signature Version 4](http://docs.amazonwebservices.com/general/latest/gr/signature-version-4.html).
-
-If you want to sign and send AWS requests in a modern browser, or an environment like [Cloudflare Workers](https://developers.cloudflare.com/workers/), then check out [aws4fetch](https://github.com/mhart/aws4fetch) – otherwise you can also bundle this library for use [in the browser](./browser).

-
-Indeed, the only AWS services that *don't* support v4 as of 2014-12-30 are
-[Import/Export](http://docs.aws.amazon.com/AWSImportExport/latest/DG/api-reference.html) and
-[SimpleDB](http://docs.aws.amazon.com/AmazonSimpleDB/latest/DeveloperGuide/SDB_API.html)
-(they only support [AWS Signature Version 2](https://github.com/mhart/aws2)).
-
-It also provides defaults for a number of core AWS headers and
-request parameters, making it very easy to query AWS services, or
-build out a fully-featured AWS library.
-
-Example
--------
-
-```javascript
-var http  = require('http'),
-    https = require('https'),
-    aws4  = require('aws4')
-
-// given an options object you could pass to http.request
-var opts = {host: 'sqs.us-east-1.amazonaws.com', path: '/?Action=ListQueues'}
-
-// alternatively (as aws4 can infer the host):
-opts = {service: 'sqs', region: 'us-east-1', path: '/?Action=ListQueues'}
-
-// alternatively (as us-east-1 is default):
-opts = {service: 'sqs', path: '/?Action=ListQueues'}
-
-aws4.sign(opts) // assumes AWS credentials are available in process.env
-
-console.log(opts)
-/*
-{
-  host: 'sqs.us-east-1.amazonaws.com',
-  path: '/?Action=ListQueues',
-  headers: {
-    Host: 'sqs.us-east-1.amazonaws.com',
-    'X-Amz-Date': '20121226T061030Z',
-    Authorization: 'AWS4-HMAC-SHA256 Credential=ABCDEF/20121226/us-east-1/sqs/aws4_request, ...'
-  }
-}
-*/
-
-// we can now use this to query AWS using the standard node.js http API
-http.request(opts, function(res) { res.pipe(process.stdout) }).end()
-/*
-<?xml version="1.0"?>
-<ListQueuesResponse xmlns="http://queue.amazonaws.com/doc/2012-11-05/">
-...
-*/
-```
-
-More options
-------------
-
-```javascript
-// you can also pass AWS credentials in explicitly (otherwise taken from process.env)
-aws4.sign(opts, {accessKeyId: '', secretAccessKey: ''})
-
-// can also add the signature to query strings
-aws4.sign({service: 's3', path: '/my-bucket?X-Amz-Expires=12345', signQuery: true})
-
-// create a utility function to pipe to stdout (with https this time)
-function request(o) { https.request(o, function(res) { res.pipe(process.stdout) }).end(o.body || '') }
-
-// aws4 can infer the HTTP method if a body is passed in
-// method will be POST and Content-Type: 'application/x-www-form-urlencoded; charset=utf-8'
-request(aws4.sign({service: 'iam', body: 'Action=ListGroups&Version=2010-05-08'}))
-/*
-<ListGroupsResponse xmlns="https://iam.amazonaws.com/doc/2010-05-08/">
-...
-*/
-
-// can specify any custom option or header as per usual
-request(aws4.sign({
-  service: 'dynamodb',
-  region: 'ap-southeast-2',
-  method: 'POST',
-  path: '/',
-  headers: {
-    'Content-Type': 'application/x-amz-json-1.0',
-    'X-Amz-Target': 'DynamoDB_20120810.ListTables'
-  },
-  body: '{}'
-}))
-/*
-{"TableNames":[]}
-...
-*/
-

-API
----
-
-### aws4.sign(requestOptions, [credentials])
-
-This calculates and populates the `Authorization` header of
-`requestOptions`, and any other necessary AWS headers and/or request
-options. Returns `requestOptions` as a convenience for chaining.
-
-`requestOptions` is an object holding the same options that the node.js
-[http.request](http://nodejs.org/docs/latest/api/http.html#http_http_request_options_callback)
-function takes.
-
-The following properties of `requestOptions` are used in the signing or
-populated if they don't already exist:
-
-- `hostname` or `host` (will be determined from `service` and `region` if not given)
-- `method` (will use `'GET'` if not given or `'POST'` if there is a `body`)
-- `path` (will use `'/'` if not given)
-- `body` (will use `''` if not given)
-- `service` (will be calculated from `hostname` or `host` if not given)
-- `region` (will be calculated from `hostname` or `host` or use `'us-east-1'` if not given)
-- `headers['Host']` (will use `hostname` or `host` or be calculated if not given)
-- `headers['Content-Type']` (will use `'application/x-www-form-urlencoded; charset=utf-8'`
-  if not given and there is a `body`)
-- `headers['Date']` (used to calculate the signature date if given, otherwise `new Date` is used)
-
-Your AWS credentials (which can be found in your
-[AWS console](https://portal.aws.amazon.com/gp/aws/securityCredentials))
-can be specified in one of two ways:
-
-- As the second argument, like this:
-
-```javascript
-aws4.sign(requestOptions, {
-  secretAccessKey: "<your-secret-access-key>",
-  accessKeyId: "<your-access-key-id>",
-  sessionToken: "<your-session-token>"
-})
-```
-
-- From `process.env`, such as this:
-
-```
-export AWS_SECRET_ACCESS_KEY="<your-secret-access-key>"
-export AWS_ACCESS_KEY_ID="<your-access-key-id>"
-export AWS_SESSION_TOKEN="<your-session-token>"
-```
-
-(will also use `AWS_ACCESS_KEY` and `AWS_SECRET_KEY` if available)
-
-The `sessionToken` property and `AWS_SESSION_TOKEN` environment variable are optional for signing
-with [IAM STS temporary credentials](http://docs.aws.amazon.com/STS/latest/UsingSTS/using-temp-creds.html).
-
-Installation
-------------
-
-With [npm](http://npmjs.org/) do:
-
-```
-npm install aws4
-```
-
-Can also be used [in the browser](./browser).
-
-Thanks
-------
-
-Thanks to [@jed](https://github.com/jed) for his
-[dynamo-client](https://github.com/jed/dynamo-client) lib where I first
-committed and subsequently extracted this code.
-
-Also thanks to the
-[official node.js AWS SDK](https://github.com/aws/aws-sdk-js) for giving
-me a start on implementing the v4 signature.

-Port of the OpenBSD `bcrypt_pbkdf` function to pure Javascript. `npm`-ified
-version of [Devi Mandiri's port](https://github.com/devi/tmp/blob/master/js/bcrypt_pbkdf.js),
-with some minor performance improvements. The code is copied verbatim (and
-un-styled) from Devi's work.
-
-This product includes software developed by Niels Provos.
-
-## API
-
-### `bcrypt_pbkdf.pbkdf(pass, passlen, salt, saltlen, key, keylen, rounds)`
-
-Derive a cryptographic key of arbitrary length from a given password and salt,
-using the OpenBSD `bcrypt_pbkdf` function. This is a combination of Blowfish and
-SHA-512.
-
-See [this article](http://www.tedunangst.com/flak/post/bcrypt-pbkdf) for
-further information.
-
-Parameters:
-
- * `pass`, a Uint8Array of length `passlen`
- * `passlen`, an integer Number
- * `salt`, a Uint8Array of length `saltlen`
- * `saltlen`, an integer Number
- * `key`, a Uint8Array of length `keylen`, will be filled with output
- * `keylen`, an integer Number
- * `rounds`, an integer Number, number of rounds of the PBKDF to run
-
-### `bcrypt_pbkdf.hash(sha2pass, sha2salt, out)`
-
-Calculate a Blowfish hash, given SHA2-512 output of a password and salt. Used as
-part of the inner round function in the PBKDF.
-
-Parameters:
-
- * `sha2pass`, a Uint8Array of length 64
- * `sha2salt`, a Uint8Array of length 64
- * `out`, a Uint8Array of length 32, will be filled with output
-
-## License
-
-This source form is a 1:1 port from the OpenBSD `blowfish.c` and `bcrypt_pbkdf.c`.
-As a result, it retains the original copyright and license. The two files are
-under slightly different (but compatible) licenses, and are here combined in
-one file. For each of the full license texts see `LICENSE`.

-# block-stream
-
-A stream of blocks.
-
-Write data into it, and it'll output data in buffer blocks the size you
-specify, padding with zeroes if necessary.
-
-```javascript
-var block = new BlockStream(512)
-fs.createReadStream("some-file").pipe(block)
-block.pipe(fs.createWriteStream("block-file"))
-```
-
-When `.end()` or `.flush()` is called, it'll pad the block with zeroes.

-## Caseless -- wrap an object to set and get property with caseless semantics but also preserve caseing.
-
-This library is incredibly useful when working with HTTP headers. It allows you to get/set/check for headers in a caseless manner while also preserving the caseing of headers the first time they are set.
-
-## Usage
-
-```javascript
-var headers = {}
-  , c = caseless(headers)
-  ;
-c.set('a-Header', 'asdf')
-c.get('a-header') === 'asdf'
-```
-
-## has(key)
-
-Has takes a name and if it finds a matching header will return that header name with the preserved caseing it was set with.
-
-```javascript
-c.has('a-header') === 'a-Header'
-```
-
-## set(key, value[, clobber=true])
-
-Set is fairly straight forward except that if the header exists and clobber is disabled it will add `','+value` to the existing header.
-
-```javascript
-c.set('a-Header', 'fdas')
-c.set('a-HEADER', 'more', false)
-c.get('a-header') === 'fdsa,more'
-```
-
-## swap(key)
-
-Swaps the casing of a header with the new one that is passed in.
-
-```javascript
-var headers = {}
-  , c = caseless(headers)
-  ;
-c.set('a-Header', 'fdas')
-c.swap('a-HEADER')
-c.has('a-header') === 'a-HEADER'
-headers === {'a-HEADER': 'fdas'}
-```

-> Terminal string styling done right
-
-[![Build Status](https://travis-ci.org/chalk/chalk.svg?branch=master)](https://travis-ci.org/chalk/chalk)
-[![Coverage Status](https://coveralls.io/repos/chalk/chalk/badge.svg?branch=master)](https://coveralls.io/r/chalk/chalk?branch=master)
-[![](http://img.shields.io/badge/unicorn-approved-ff69b4.svg)](https://www.youtube.com/watch?v=9auOCbH5Ns4)
-
-
-[colors.js](https://github.com/Marak/colors.js) used to be the most popular string styling module, but it has serious deficiencies like extending `String.prototype` which causes all kinds of [problems](https://github.com/yeoman/yo/issues/68). Although there are other ones, they either do too much or not enough.
-
-**Chalk is a clean and focused alternative.**
-
-![](https://github.com/chalk/ansi-styles/raw/master/screenshot.png)
-
-
-## Why
-
-- Highly performant
-- Doesn't extend `String.prototype`
-- Expressive API
-- Ability to nest styles
-- Clean and focused
-- Auto-detects color support
-- Actively maintained
-- [Used by ~4500 modules](https://www.npmjs.com/browse/depended/chalk) as of July 15, 2015
-
-
-## Install
-
-```
-$ npm install --save chalk
-```
-
-
-## Usage
-
-Chalk comes with an easy to use composable API where you just chain and nest the styles you want.
-
-```js
-var chalk = require('chalk');
-
-// style a string
-chalk.blue('Hello world!');
-
-// combine styled and normal strings
-chalk.blue('Hello') + 'World' + chalk.red('!');
-
-// compose multiple styles using the chainable API
-chalk.blue.bgRed.bold('Hello world!');
-
-// pass in multiple arguments
-chalk.blue('Hello', 'World!', 'Foo', 'bar', 'biz', 'baz');
-
-// nest styles
-chalk.red('Hello', chalk.underline.bgBlue('world') + '!');
-
-// nest styles of the same type even (color, underline, background)
-chalk.green(
-	'I am a green line ' +
-	chalk.blue.underline.bold('with a blue substring') +
-	' that becomes green again!'
-);
-```
-
-Easily define your own themes.
-
-```js
-var chalk = require('chalk');
-var error = chalk.bold.red;
-console.log(error('Error!'));
-```
-
-Take advantage of console.log [string substitution](http://nodejs.org/docs/latest/api/console.html#console_console_log_data).
-
-```js
-var name = 'Sindre';
-console.log(chalk.green('Hello %s'), name);
-//=> Hello Sindre
-```
-
-
-## API
-
-### chalk.`<style>[.<style>...](string, [string...])`
-
-Example: `chalk.red.bold.underline('Hello', 'world');`
-
-Chain [styles](#styles) and call the last one as a method with a string argument. Order doesn't matter, and later styles take precedent in case of a conflict. This simply means that `Chalk.red.yellow.green` is equivalent to `Chalk.green`.
-
-Multiple arguments will be separated by space.
-
-### chalk.enabled
-
-Color support is automatically detected, but you can override it by setting the `enabled` property. You should however only do this in your own code as it applies globally to all chalk consumers.
-
-If you need to change this in a reusable module create a new instance:
-
-```js
-var ctx = new chalk.constructor({enabled: false});
-```
-
-### chalk.supportsColor
-
-Detect whether the terminal [supports color](https://github.com/chalk/supports-color). Used internally and handled for you, but exposed for convenience.
-
-Can be overridden by the user with the flags `--color` and `--no-color`. For situations where using `--color` is not possible, add an environment variable `FORCE_COLOR` with any value to force color. Trumps `--no-color`.
-
-### chalk.styles
-
-Exposes the styles as [ANSI escape codes](https://github.com/chalk/ansi-styles).
-
-Generally not useful, but you might need just the `.open` or `.close` escape code if you're mixing externally styled strings with your own.
-
-```js
-var chalk = require('chalk');
-
-console.log(chalk.styles.red);
-//=> {open: '\u001b[31m', close: '\u001b[39m'}
-
-console.log(chalk.styles.red.open + 'Hello' + chalk.styles.red.close);
-```
-
-### chalk.hasColor(string)
-
-Check whether a string [has color](https://github.com/chalk/has-ansi).
-
-### chalk.stripColor(string)
-
-[Strip color](https://github.com/chalk/strip-ansi) from a string.
-
-Can be useful in combination with `.supportsColor` to strip color on externally styled text when it's not supported.
-
-Example:
-
-```js
-var chalk = require('chalk');
-var styledString = getText();
-
-if (!chalk.supportsColor) {
-	styledString = chalk.stripColor(styledString);
-}
-```
-
-
-## Styles
-
-### Modifiers
-
-- `reset`
-- `bold`
-- `dim`
-- `italic` *(not widely supported)*
-- `underline`
-- `inverse`
-- `hidden`
-- `strikethrough` *(not widely supported)*
-
-### Colors
-
-- `black`
-- `red`
-- `green`
-- `yellow`
-- `blue` *(on Windows the bright version is used as normal blue is illegible)*
-- `magenta`
-- `cyan`
-- `white`
-- `gray`
-
-### Background colors
-
-- `bgBlack`
-- `bgRed`
-- `bgGreen`
-- `bgYellow`
-- `bgBlue`
-- `bgMagenta`
-- `bgCyan`
-- `bgWhite`
-
-
-## 256-colors
-
-Chalk does not support anything other than the base eight colors, which guarantees it will work on all terminals and systems. Some terminals, specifically `xterm` compliant ones, will support the full range of 8-bit colors. For this the lower level [ansi-256-colors](https://github.com/jbnicolai/ansi-256-colors) package can be used.
-
-
-## Windows
-
-If you're on Windows, do yourself a favor and use [`cmder`](http://bliker.github.io/cmder/) instead of `cmd.exe`.

-# color-convert
-
-[![Build Status](https://travis-ci.org/Qix-/color-convert.svg?branch=master)](https://travis-ci.org/Qix-/color-convert)
-
-Color-convert is a color conversion library for JavaScript and node.
-It converts all ways between `rgb`, `hsl`, `hsv`, `hwb`, `cmyk`, `ansi`, `ansi16`, `hex` strings, and CSS `keyword`s (will round to closest):
-
-```js
-var convert = require('color-convert');
-
-convert.rgb.hsl(140, 200, 100);             // [96, 48, 59]
-convert.keyword.rgb('blue');                // [0, 0, 255]
-
-var rgbChannels = convert.rgb.channels;     // 3
-var cmykChannels = convert.cmyk.channels;   // 4
-var ansiChannels = convert.ansi16.channels; // 1
-```
-
-# Install
-
-```console
-$ npm install color-convert
-```
-
-# API
-
-Simply get the property of the _from_ and _to_ conversion that you're looking for.
-
-All functions have a rounded and unrounded variant. By default, return values are rounded. To get the unrounded (raw) results, simply tack on `.raw` to the function.
-
-All 'from' functions have a hidden property called `.channels` that indicates the number of channels the function expects (not including alpha).
-
-```js
-var convert = require('color-convert');
-
-// Hex to LAB
-convert.hex.lab('DEADBF');         // [ 76, 21, -2 ]
-convert.hex.lab.raw('DEADBF');     // [ 75.56213190997677, 20.653827952644754, -2.290532499330533 ]

-### Arrays
-All functions that accept multiple arguments also support passing an array.
-
-Note that this does **not** apply to functions that convert from a color that only requires one value (e.g. `keyword`, `ansi256`, `hex`, etc.)
-
-```js
-var convert = require('color-convert');
-
-convert.rgb.hex(123, 45, 67);      // '7B2D43'
-convert.rgb.hex([123, 45, 67]);    // '7B2D43'
-```
-
-## Routing
-
-Conversions that don't have an _explicitly_ defined conversion (in [conversions.js](conversions.js)), but can be converted by means of sub-conversions (e.g. XYZ -> **RGB** -> CMYK), are automatically routed together. This allows just about any color model supported by `color-convert` to be converted to any other model, so long as a sub-conversion path exists. This is also true for conversions requiring more than one step in between (e.g. LCH -> **LAB** -> **XYZ** -> **RGB** -> Hex).
-
-Keep in mind that extensive conversions _may_ result in a loss of precision, and exist only to be complete. For a list of "direct" (single-step) conversions, see [conversions.js](conversions.js).

-# combined-stream
-
-A stream that emits multiple other streams one after another.
-
-**NB** Currently `combined-stream` works with streams version 1 only. There is ongoing effort to switch this library to streams version 2. Any help is welcome. :) Meanwhile you can explore other libraries that provide streams2 support with more or less compatibility with `combined-stream`.
-
-- [combined-stream2](https://www.npmjs.com/package/combined-stream2): A drop-in streams2-compatible replacement for the combined-stream module.
-
-- [multistream](https://www.npmjs.com/package/multistream): A stream that emits multiple other streams one after another.
-
-## Installation
-
-``` bash
-npm install combined-stream
-```
-
-## Usage
-
-Here is a simple example that shows how you can use combined-stream to combine
-two files into one:
-
-``` javascript
-var CombinedStream = require('combined-stream');
-var fs = require('fs');
-
-var combinedStream = CombinedStream.create();
-combinedStream.append(fs.createReadStream('file1.txt'));
-combinedStream.append(fs.createReadStream('file2.txt'));
-
-combinedStream.pipe(fs.createWriteStream('combined.txt'));
-```
-
-While the example above works great, it will pause all source streams until
-they are needed. If you don't want that to happen, you can set `pauseStreams`
-to `false`:
-
-``` javascript
-var CombinedStream = require('combined-stream');
-var fs = require('fs');
-
-var combinedStream = CombinedStream.create({pauseStreams: false});
-combinedStream.append(fs.createReadStream('file1.txt'));
-combinedStream.append(fs.createReadStream('file2.txt'));
-
-combinedStream.pipe(fs.createWriteStream('combined.txt'));
-```
-
-However, what if you don't have all the source streams yet, or you don't want
-to allocate the resources (file descriptors, memory, etc.) for them right away?
-Well, in that case you can simply provide a callback that supplies the stream
-by calling a `next()` function:
-
-``` javascript
-var CombinedStream = require('combined-stream');
-var fs = require('fs');
-
-var combinedStream = CombinedStream.create();
-combinedStream.append(function(next) {
-  next(fs.createReadStream('file1.txt'));
-});
-combinedStream.append(function(next) {
-  next(fs.createReadStream('file2.txt'));
-});
-
-combinedStream.pipe(fs.createWriteStream('combined.txt'));
-```
-
-## API
-
-### CombinedStream.create([options])
-
-Returns a new combined stream object. Available options are:
-
-* `maxDataSize`
-* `pauseStreams`
-
-The effect of those options is described below.
-
-### combinedStream.pauseStreams = `true`
-
-Whether to apply back pressure to the underlaying streams. If set to `false`,
-the underlaying streams will never be paused. If set to `true`, the
-underlaying streams will be paused right after being appended, as well as when
-`delayedStream.pipe()` wants to throttle.
-
-### combinedStream.maxDataSize = `2 * 1024 * 1024`
-
-The maximum amount of bytes (or characters) to buffer for all source streams.
-If this value is exceeded, `combinedStream` emits an `'error'` event.
-
-### combinedStream.dataSize = `0`
-
-The amount of bytes (or characters) currently buffered by `combinedStream`.
-
-### combinedStream.append(stream)
-
-Appends the given `stream` to the combinedStream object. If `pauseStreams` is
-set to `true, this stream will also be paused right away.
-
-`streams` can also be a function that takes one parameter called `next`. `next`
-is a function that must be invoked in order to provide the `next` stream, see
-example above.
-
-Regardless of how the `stream` is appended, combined-stream always attaches an
-`'error'` listener to it, so you don't have to do that manually.
-
-Special case: `stream` can also be a String or Buffer.
-
-### combinedStream.write(data)
-
-You should not call this, `combinedStream` takes care of piping the appended
-streams into itself for you.
-
-### combinedStream.resume()
-
-Causes `combinedStream` to start drain the streams it manages. The function is
-idempotent, and also emits a `'resume'` event each time which usually goes to
-the stream that is currently being drained.
-
-### combinedStream.pause();
-
-If `combinedStream.pauseStreams` is set to `false`, this does nothing.
-Otherwise a `'pause'` event is emitted, this goes to the stream that is
-currently being drained, so you can use it to apply back pressure.
-
-### combinedStream.end();
-
-Sets `combinedStream.writable` to false, emits an `'end'` event, and removes
-all streams from the queue.
-
-### combinedStream.destroy();
-
-Same as `combinedStream.end()`, except it emits a `'close'` event instead of
-`'end'`.

-# Console Control Strings
-
-A library of cross-platform tested terminal/console command strings for
-doing things like color and cursor positioning.  This is a subset of both
-ansi and vt100.  All control codes included work on both Windows & Unix-like
-OSes, except where noted.
-
-## Usage
-
-```js
-var consoleControl = require('console-control-strings')
-
-console.log(consoleControl.color('blue','bgRed', 'bold') + 'hi there' + consoleControl.color('reset'))
-process.stdout.write(consoleControl.goto(75, 10))
-```
-
-## Why Another?
-
-There are tons of libraries similar to this one.  I wanted one that was:
-
-1. Very clear about compatibility goals.
-2. Could emit, for instance, a start color code without an end one.
-3. Returned strings w/o writing to streams.
-4. Was not weighed down with other unrelated baggage.
-
-## Functions
-
-### var code = consoleControl.up(_num = 1_)
-
-Returns the escape sequence to move _num_ lines up.
-
-### var code = consoleControl.down(_num = 1_)
-
-Returns the escape sequence to move _num_ lines down.
-
-### var code = consoleControl.forward(_num = 1_)
-
-Returns the escape sequence to move _num_ lines righ.
-
-### var code = consoleControl.back(_num = 1_)
-
-Returns the escape sequence to move _num_ lines left.
-
-### var code = consoleControl.nextLine(_num = 1_)
-
-Returns the escape sequence to move _num_ lines down and to the beginning of
-the line.
-
-### var code = consoleControl.previousLine(_num = 1_)
-
-Returns the escape sequence to move _num_ lines up and to the beginning of
-the line.
-
-### var code = consoleControl.eraseData()
-
-Returns the escape sequence to erase everything from the current cursor
-position to the bottom right of the screen.  This is line based, so it
-erases the remainder of the current line and all following lines.
-
-### var code = consoleControl.eraseLine()
-
-Returns the escape sequence to erase to the end of the current line.
-
-### var code = consoleControl.goto(_x_, _y_)
-
-Returns the escape sequence to move the cursor to the designated position. 
-Note that the origin is _1, 1_ not _0, 0_.
-
-### var code = consoleControl.gotoSOL()
-
-Returns the escape sequence to move the cursor to the beginning of the
-current line. (That is, it returns a carriage return, `\r`.)
-
-### var code = consoleControl.beep()
-
-Returns the escape sequence to cause the termianl to beep.  (That is, it
-returns unicode character `\x0007`, a Control-G.)
-
-### var code = consoleControl.hideCursor()
-
-Returns the escape sequence to hide the cursor.
-
-### var code = consoleControl.showCursor()
-
-Returns the escape sequence to show the cursor.
-
-### var code = consoleControl.color(_colors = []_)
-
-### var code = consoleControl.color(_color1_, _color2_, _…_, _colorn_)
-
-Returns the escape sequence to set the current terminal display attributes
-(mostly colors).  Arguments can either be a list of attributes or an array
-of attributes.  The difference between passing in an array or list of colors
-and calling `.color` separately for each one, is that in the former case a
-single escape sequence will be produced where as in the latter each change
-will have its own distinct escape sequence.  Each attribute can be one of:
-
-* Reset:
-  * **reset** – Reset all attributes to the terminal default.
-* Styles:
-  * **bold** – Display text as bold.  In some terminals this means using a
-    bold font, in others this means changing the color.  In some it means
-    both.
-  * **italic** – Display text as italic. This is not available in most Windows terminals.
-  * **underline** – Underline text. This is not available in most Windows Terminals.
-  * **inverse** – Invert the foreground and background colors.
-  * **stopBold** – Do not display text as bold.
-  * **stopItalic** – Do not display text as italic.
-  * **stopUnderline** – Do not underline text.
-  * **stopInverse** – Do not invert foreground and background.
-* Colors:
-  * **white**
-  * **black**
-  * **blue**
-  * **cyan**
-  * **green**
-  * **magenta**
-  * **red**
-  * **yellow**
-  * **grey** / **brightBlack**
-  * **brightRed**
-  * **brightGreen**
-  * **brightYellow**
-  * **brightBlue**
-  * **brightMagenta**
-  * **brightCyan**
-  * **brightWhite**
-* Background Colors:
-  * **bgWhite**
-  * **bgBlack**
-  * **bgBlue**
-  * **bgCyan**
-  * **bgGreen**
-  * **bgMagenta**
-  * **bgRed**
-  * **bgYellow**
-  * **bgGrey** / **bgBrightBlack**
-  * **bgBrightRed**
-  * **bgBrightGreen**
-  * **bgBrightYellow**
-  * **bgBrightBlue**
-  * **bgBrightMagenta**
-  * **bgBrightCyan**
-  * **bgBrightWhite**

-
-A cross platform solution to node's spawn and spawnSync.
-
-
-## Installation
-
-`$ npm install cross-spawn`
-
-If you are using `spawnSync` on node 0.10 or older, you will also need to install `spawn-sync`:
-
-`$ npm install spawn-sync`
-
-
-## Why
-
-Node has issues when using spawn on Windows:
-
-- It ignores [PATHEXT](https://github.com/joyent/node/issues/2318)
-- It does not support [shebangs](http://pt.wikipedia.org/wiki/Shebang)
-- It does not allow you to run `del` or `dir`
-- It does not properly escape arguments with spaces or special characters
-
-All these issues are handled correctly by `cross-spawn`.
-There are some known modules, such as [win-spawn](https://github.com/ForbesLindesay/win-spawn), that try to solve this but they are either broken or provide faulty escaping of shell arguments.
-
-
-## Usage
-
-Exactly the same way as node's [`spawn`](https://nodejs.org/api/child_process.html#child_process_child_process_spawn_command_args_options) or [`spawnSync`](https://nodejs.org/api/child_process.html#child_process_child_process_spawnsync_command_args_options), so it's a drop in replacement.
-
-```javascript
-var spawn = require('cross-spawn');
-
-// Spawn NPM asynchronously
-var child = spawn('npm', ['list', '-g', '-depth', '0'], { stdio: 'inherit' });
-
-// Spawn NPM synchronously
-var results = spawn.sync('npm', ['list', '-g', '-depth', '0'], { stdio: 'inherit' });
-```
-
-
-## Tests
-
-`$ npm test`
-

-# lru cache
-
-A cache object that deletes the least-recently-used items.
-
-[![Build Status](https://travis-ci.org/isaacs/node-lru-cache.svg?branch=master)](https://travis-ci.org/isaacs/node-lru-cache) [![Coverage Status](https://coveralls.io/repos/isaacs/node-lru-cache/badge.svg?service=github)](https://coveralls.io/github/isaacs/node-lru-cache)
-
-## Installation:
-
-```javascript
-npm install lru-cache --save
-```
-
-## Usage:
-
-```javascript
-var LRU = require("lru-cache")
-  , options = { max: 500
-              , length: function (n, key) { return n * 2 + key.length }
-              , dispose: function (key, n) { n.close() }
-              , maxAge: 1000 * 60 * 60 }
-  , cache = LRU(options)
-  , otherCache = LRU(50) // sets just the max size
-
-cache.set("key", "value")
-cache.get("key") // "value"
-
-// non-string keys ARE fully supported
-// but note that it must be THE SAME object, not
-// just a JSON-equivalent object.
-var someObject = { a: 1 }
-cache.set(someObject, 'a value')
-// Object keys are not toString()-ed
-cache.set('[object Object]', 'a different value')
-assert.equal(cache.get(someObject), 'a value')
-// A similar object with same keys/values won't work,
-// because it's a different object identity
-assert.equal(cache.get({ a: 1 }), undefined)
-
-cache.reset()    // empty the cache
-```
-
-If you put more stuff in it, then items will fall out.
-
-If you try to put an oversized thing in it, then it'll fall out right
-away.
-
-## Options
-
-* `max` The maximum size of the cache, checked by applying the length
-  function to all values in the cache.  Not setting this is kind of
-  silly, since that's the whole purpose of this lib, but it defaults
-  to `Infinity`.
-* `maxAge` Maximum age in ms.  Items are not pro-actively pruned out
-  as they age, but if you try to get an item that is too old, it'll
-  drop it and return undefined instead of giving it to you.
-* `length` Function that is used to calculate the length of stored
-  items.  If you're storing strings or buffers, then you probably want
-  to do something like `function(n, key){return n.length}`.  The default is
-  `function(){return 1}`, which is fine if you want to store `max`
-  like-sized things.  The item is passed as the first argument, and
-  the key is passed as the second argumnet.
-* `dispose` Function that is called on items when they are dropped
-  from the cache.  This can be handy if you want to close file
-  descriptors or do other cleanup tasks when items are no longer
-  accessible.  Called with `key, value`.  It's called *before*
-  actually removing the item from the internal cache, so if you want
-  to immediately put it back in, you'll have to do that in a
-  `nextTick` or `setTimeout` callback or it won't do anything.
-* `stale` By default, if you set a `maxAge`, it'll only actually pull
-  stale items out of the cache when you `get(key)`.  (That is, it's
-  not pre-emptively doing a `setTimeout` or anything.)  If you set
-  `stale:true`, it'll return the stale value before deleting it.  If
-  you don't set this, then it'll return `undefined` when you try to
-  get a stale entry, as if it had already been deleted.
-* `noDisposeOnSet` By default, if you set a `dispose()` method, then
-  it'll be called whenever a `set()` operation overwrites an existing
-  key.  If you set this option, `dispose()` will only be called when a
-  key falls out of the cache, not when it is overwritten.
-
-## API
-
-* `set(key, value, maxAge)`
-* `get(key) => value`
-
-    Both of these will update the "recently used"-ness of the key.
-    They do what you think. `maxAge` is optional and overrides the
-    cache `maxAge` option if provided.
-
-    If the key is not found, `get()` will return `undefined`.
-
-    The key and val can be any value.
-
-* `peek(key)`
-
-    Returns the key value (or `undefined` if not found) without
-    updating the "recently used"-ness of the key.
-
-    (If you find yourself using this a lot, you *might* be using the
-    wrong sort of data structure, but there are some use cases where
-    it's handy.)
-
-* `del(key)`
-
-    Deletes a key out of the cache.
-
-* `reset()`
-
-    Clear the cache entirely, throwing away all values.
-
-* `has(key)`
-
-    Check if a key is in the cache, without updating the recent-ness
-    or deleting it for being stale.
-
-* `forEach(function(value,key,cache), [thisp])`
-
-    Just like `Array.prototype.forEach`.  Iterates over all the keys
-    in the cache, in order of recent-ness.  (Ie, more recently used
-    items are iterated over first.)
-
-* `rforEach(function(value,key,cache), [thisp])`
-
-    The same as `cache.forEach(...)` but items are iterated over in
-    reverse order.  (ie, less recently used items are iterated over
-    first.)
-
-* `keys()`
-
-    Return an array of the keys in the cache.
-
-* `values()`
-
-    Return an array of the values in the cache.
-
-* `length`
-
-    Return total length of objects in cache taking into account
-    `length` options function.
-
-* `itemCount`
-
-    Return total quantity of objects currently in cache. Note, that
-    `stale` (see options) items are returned as part of this item
-    count.
-
-* `dump()`
-
-    Return an array of the cache entries ready for serialization and usage
-    with 'destinationCache.load(arr)`.
-
-* `load(cacheEntriesArray)`
-
-    Loads another cache entries array, obtained with `sourceCache.dump()`,
-    into the cache. The destination cache is reset before loading new entries
-
-* `prune()`
-
-    Manually iterates over the entire cache proactively pruning old entries

-
-> Track the list of currently unhandled promise rejections.
-
-
-## Install
-
-```
-$ npm install --save currently-unhandled
-```
-
-
-## Usage
-
-```js
-const currentlyUnhandled = require('currently-unhandled')(); // <- note the invocation
-
-var fooError = new Error('foo');
-var p = Promise.reject(new Error('foo'));
-
-// on the next tick - unhandled rejected promise is added to the list:
-currentlyUnhandled();
-//=> [{promise: p, reason: fooError}]'
-
-p.catch(() => {});
-
-// on the next tick - handled promise is now removed from the list:
-currentlyUnhandled();
-//=> [];
-```
-
-## API
-
-### currentlyUnhandled()
-
-Returns an array of objects with `promise` and `reason` properties representing the rejected promises that currently do not have a rejection handler. The list grows and shrinks as unhandledRejections are published, and later handled.
-
-## Browser Support
-
-This module can be bundled with `browserify`. At time of writing, it will work with native Promises in the Chrome browser only. For best cross-browser support, use `bluebird` instead of native Promise support in browsers.

-# node-dashdash changelog

-## not yet released
-
-(nothing yet)
-
-## 1.14.1
-
-- [issue #30] Change the output used by dashdash's Bash completion support to
-  indicate "there are no completions for this argument" to cope with different
-  sorting rules on different Bash/platforms. For example:
-
-        $ triton -v -p test2 package get <TAB>          # before
-        ##-no -tritonpackage- completions-##
-
-        $ triton -v -p test2 package get <TAB>          # after
-        ##-no-completion- -results-##
-
-## 1.14.0
-
-- New `synopsisFromOpt(<option spec>)` function. This will be used by
-  [node-cmdln](https://github.com/trentm/node-cmdln) to put together a synopsis
-  of options for a command. Some examples:
-
-        > synopsisFromOpt({names: ['help', 'h'], type: 'bool'});
-        '[ --help | -h ]'
-        > synopsisFromOpt({name: 'file', type: 'string', helpArg: 'FILE'});
-        '[ --file=FILE ]'
-
-
-## 1.13.1
-
-- [issue #20] `bashCompletionSpecFromOptions` breaks on an options array with
-  an empty-string group.
-
-
-## 1.13.0
-
-- Update assert-plus dep to 1.x to get recent fixes (particularly for
-  `assert.optional*`).
-
-- Drop testing (and official support in packages.json#engines) for node 0.8.x.
-  Add testing against node 5.x and 4.x with `make testall`.
-
-- [pull #16] Change the `positiveInteger` type to NOT accept zero (0).
-  For those who might need the old behaviour, see
-  "examples/custom-option-intGteZero.js".  (By Dave Pacheco.)
-
-
-## 1.12.2
-
-- Bash completion: Add `argtypes` to specify the types of positional args.
-  E.g. this would allow you to have an `ssh` command with `argtypes = ['host',
-  'cmd']` for bash completion. You then have to provide Bash functions to
-  handle completing those types via the `specExtra` arg. See
-  "[examples/ddcompletion.js](examples/ddcompletion.js)" for an example.
-
-- Bash completion: Tweak so that options or only offered as completions when
-  there is a leading '-'. E.g. `mytool <TAB>` does NOT offer options, `mytool
-  -<TAB>` *does*. Without this, a tool with options would never be able to
-  fallback to Bash's "default" completion. For example `ls <TAB>` wouldn't
-  result in filename completion. Now it will.
-
-- Bash completion: A workaround for not being able to explicitly have *no*
-  completion results. Because dashdash's completion uses `complete -o default`,
-  we fallback to Bash's "default" completion (typically for filename
-  completion). Before this change, an attempt to explicitly say "there are
-  no completions that match" would unintentionally trigger filename completion.
-  Instead as a workaround we return:
-
-        $ ddcompletion --none <TAB>         # the 'none' argtype
-        ##-no           completions-##
-
-        $ ddcompletion                      # a custom 'fruit' argtype
-        apple   banana  orange
-        $ ddcompletion z
-        ##-no           -fruit-         completions-##
-
-  This is a bit of a hack, but IMO a better experience than the surprise
-  of matching a local filename beginning with 'z', which isn't, in this
-  case, a "fruit".
-
-## 1.12.1
-
-- Bash completion: Document `<option spec>.completionType`. Add `includeHidden`
-  option to `bashCompletionSpecFromOptions()`. Add support for dealing with
-  hidden subcmds.
-
-
-## 1.12.0
-
-- Support for generating Bash completion files. See the "Bash completion"
-  section of the README.md and "examples/ddcompletion.js" for an example.
-
-
-## 1.11.0
-
-- Add the `arrayFlatten` boolean option to `dashdash.addOptionType` used for
-  custom option types. This allows one to create an `arrayOf...` option type
-  where each usage of the option can return multiple results. For example:
-
-        node mytool.js --foo a,b --foo c
-
-  We could define an option type for `--foo` such that
-  `opts.foo = ['a', 'b', 'c']`. See
-  "[examples/custom-option-arrayOfCommaSepString.js](examples/custom-option-arrayOfCommaSepString.js)"
-  for an example.
-
-
-## 1.10.1
-
-- Trim the published package to the minimal bits. Before: 24K tarball, 144K unpacked.
-  After: 12K tarball, 48K unpacked. `npm` won't let me drop the README.md. :)
-
-
-## 1.10.0
-
-- [issue #9] Support `includeDefault` in help config (similar to `includeEnv`) to have a
-  note of an option's default value, if any, in help output.
-- [issue #11] Fix option group breakage introduced in v1.9.0.
-
-
-## 1.9.0
-
-- [issue #10] Custom option types added with `addOptionType` can specify a
-  "default" value. See "examples/custom-option-fruit.js".
-
-
-## 1.8.0
-
-- Support `hidden: true` in an option spec to have help output exclude this
-  option.
-
-
-## 1.7.3
-
-- [issue #8] Fix parsing of a short option group when one of the
-  option takes an argument. For example, consider `tail` with
-  a `-f` boolean option and a `-n` option that takes a number
-  argument. This should parse:
-
-        tail -fn5
-
-  Before this change, that would not parse correctly.
-  It is suspected that this was introduced in version 1.4.0
-  (with commit 656fa8bc71c372ebddad0a7026bd71611e2ec99a).
-
-
-## 1.7.2
-
-- Known issues: #8
-
-- Exclude 'tools/' dir in packages published to npm.
-
-
-## 1.7.1
-
-- Known issues: #8
-
-- Support an option group *empty string* value:
-
-        ...
-        { group: '' },
-        ...
-
-  to render as a blank line in option help. This can help separate loosely
-  related sets of options without resorting to a title for option groups.
-
-
-## 1.7.0
-
-- Known issues: #8
-
-- [pull #7] Support for `<parser>.help({helpWrap: false, ...})` option to be able
-  to fully control the formatting for option help (by Patrick Mooney) `helpWrap:
-  false` can also be set on individual options in the option objects, e.g.:
-
-        var options = [
-            {
-              names: ['foo'],
-              type: 'string',
-              helpWrap: false,
-              help: 'long help with\n  newlines' +
-                '\n  spaces\n  and such\nwill render correctly'
-            },
-            ...
-        ];
-
-
-## 1.6.0
-
-- Known issues: #8
-
-- [pull #6] Support headings between groups of options (by Joshua M. Clulow)
-  so that this code:
-
-        var options = [
-            { group: 'Armament Options' },
-            { names: [ 'weapon', 'w' ], type: 'string' },
-            { group: 'General Options' },
-            { names: [ 'help', 'h' ], type: 'bool' }
-        ];
-        ...
-
-  will give you this help output:
-
-        ...
-          Armament Options:
-            -w, --weapon
-
-          General Options:
-            -h, --help
-        ...
-
-
-## 1.5.0
-
-- Known issues: #8
-
-- Add support for adding custom option types. "examples/custom-option-duration.js"
-  shows an example adding a "duration" option type.
-
-        $ node custom-option-duration.js -t 1h
-        duration: 3600000 ms
-        $ node custom-option-duration.js -t 1s
-        duration: 1000 ms
-        $ node custom-option-duration.js -t 5d
-        duration: 432000000 ms
-        $ node custom-option-duration.js -t bogus
-        custom-option-duration.js: error: arg for "-t" is not a valid duration: "bogus"
-
-  A custom option type is added via:
-
-        var dashdash = require('dashdash');
-        dashdash.addOptionType({
-            name: '...',
-            takesArg: true,
-            helpArg: '...',
-            parseArg: function (option, optstr, arg) {
-                ...
-            }
-        });

-- [issue #4] Add `date` and `arrayOfDate` option types. They accept these date
-  formats: epoch second times (e.g. 1396031701) and ISO 8601 format:
-  `YYYY-MM-DD[THH:MM:SS[.sss][Z]]` (e.g. "2014-03-28",
-  "2014-03-28T18:35:01.489Z"). See "examples/date.js" for an example usage.
-
-        $ node examples/date.js -s 2014-01-01 -e $(date +%s)
-        start at 2014-01-01T00:00:00.000Z
-        end at 2014-03-29T04:26:18.000Z

-## 1.4.0
-
-- Known issues: #8
-
-- [pull #2, pull #3] Add a `allowUnknown: true` option on `createParser` to
-  allow unknown options to be passed through as `opts._args` instead of parsing
-  throwing an exception (by https://github.com/isaacs).
-
-  See 'allowUnknown' in the README for a subtle caveat.
-
-
-## 1.3.2
-
-- Fix a subtlety where a *bool* option using both `env` and `default` didn't
-  work exactly correctly. If `default: false` then all was fine (by luck).
-  However, if you had an option like this:
-
-        options: [ {
-            names: ['verbose', 'v'],
-            env: 'FOO_VERBOSE',
-            'default': true,    // <--- this
-            type: 'bool'
-        } ],
-
-  wanted `FOO_VERBOSE=0` to make the option false, then you need the fix
-  in this version of dashdash.
-
-
-## 1.3.1
-
-- [issue #1] Fix an envvar not winning over an option 'default'. Previously
-  an option with both `default` and `env` would never take a value from the
-  environment variable. E.g. `FOO_FILE` would never work here:
-
-        options: [ {
-            names: ['file', 'f'],
-            env: 'FOO_FILE',
-            'default': 'default.file',
-            type: 'string'
-        } ],
-
-
-## 1.3.0
-
-- [Backward incompatible change for boolean envvars] Change the
-  interpretation of environment variables for boolean options to consider '0'
-  to be false. Previous to this *any* value to the envvar was considered
-  true -- which was quite misleading. Example:
-
-        $ FOO_VERBOSE=0 node examples/foo.js
-        # opts: { verbose: [ false ],
-          _order: [ { key: 'verbose', value: false, from: 'env' } ],
-          _args: [] }
-        # args: []
-
-
-## 1.2.1
-
-- Fix for `parse.help({includeEnv: true, ...})` handling to ensure that an
-  option with an `env` **but no `help`** still has the "Environment: ..."
-  output. E.g.:
-
-        { names: ['foo'], type: 'string', env: 'FOO' }
-
-        ...
-
-        --foo=ARG      Environment: FOO=ARG
-
-
-## 1.2.0
-
-- Transform the option key on the `opts` object returned from
-  `<parser>.parse()` for convenience. Currently this is just
-  `s/-/_/g`, e.g. '--dry-run' -> `opts.dry_run`. This allow one to use hyphen
-  in option names (common) but not have to do silly things like
-  `opt["dry-run"]` to access the parsed results.
-
-
-## 1.1.0
-
-- Environment variable integration. Envvars can be associated with an option,
-  then option processing will fallback to using that envvar if defined and
-  if the option isn't specified in argv. See the "Environment variable
-  integration" section in the README.
-
-- Change the `<parser>.parse()` signature to take a single object with keys
-  for arguments. The old signature is still supported.
-
-- `dashdash.createParser(CONFIG)` alternative to `new dashdash.Parser(CONFIG)`
-  a la many node-land APIs.
-
-
-## 1.0.2
-
-- Add "positiveInteger" and "arrayOfPositiveInteger" option types that only
-  accept positive integers.
-
-- Add "integer" and "arrayOfInteger" option types that accepts only integers.
-  Note that, for better or worse, these do NOT accept: "0x42" (hex), "1e2"
-  (with exponent) or "1.", "3.0" (floats).
-
-
-## 1.0.1
-
-- Fix not modifying the given option spec objects (which breaks creating
-  a Parser with them more than once).
-
-
-## 1.0.0
-
-First release.

-A light, featureful and explicit option parsing library for node.js.
-
-[Why another one? See below](#why). tl;dr: The others I've tried are one of
-too loosey goosey (not explicit), too big/too many deps, or ill specified.
-YMMV.
-
-Follow <a href="https://twitter.com/intent/user?screen_name=trentmick" target="_blank">@trentmick</a>
-for updates to node-dashdash.
-
-# Install
-
-    npm install dashdash
-
-
-# Usage
-
-```javascript
-var dashdash = require('dashdash');
-
-// Specify the options. Minimally `name` (or `names`) and `type`
-// must be given for each.
-var options = [
-    {
-        // `names` or a single `name`. First element is the `opts.KEY`.
-        names: ['help', 'h'],
-        // See "Option specs" below for types.
-        type: 'bool',
-        help: 'Print this help and exit.'
-    }
-];
-
-// Shortcut form. As called it infers `process.argv`. See below for
-// the longer form to use methods like `.help()` on the Parser object.
-var opts = dashdash.parse({options: options});
-
-console.log("opts:", opts);
-console.log("args:", opts._args);
-```
-
-
-# Longer Example
-
-A more realistic [starter script "foo.js"](./examples/foo.js) is as follows.
-This also shows using `parser.help()` for formatted option help.
-
-```javascript
-var dashdash = require('./lib/dashdash');
-
-var options = [
-    {
-        name: 'version',
-        type: 'bool',
-        help: 'Print tool version and exit.'
-    },
-    {
-        names: ['help', 'h'],
-        type: 'bool',
-        help: 'Print this help and exit.'
-    },
-    {
-        names: ['verbose', 'v'],
-        type: 'arrayOfBool',
-        help: 'Verbose output. Use multiple times for more verbose.'
-    },
-    {
-        names: ['file', 'f'],
-        type: 'string',
-        help: 'File to process',
-        helpArg: 'FILE'
-    }
-];
-
-var parser = dashdash.createParser({options: options});
-try {
-    var opts = parser.parse(process.argv);
-} catch (e) {
-    console.error('foo: error: %s', e.message);
-    process.exit(1);
-}
-
-console.log("# opts:", opts);
-console.log("# args:", opts._args);
-
-// Use `parser.help()` for formatted options help.
-if (opts.help) {
-    var help = parser.help({includeEnv: true}).trimRight();
-    console.log('usage: node foo.js [OPTIONS]\n'
-                + 'options:\n'
-                + help);
-    process.exit(0);
-}
-
-// ...
-```
-
-
-Some example output from this script (foo.js):
-
-```
-$ node foo.js -h
-# opts: { help: true,
-  _order: [ { name: 'help', value: true, from: 'argv' } ],
-  _args: [] }
-# args: []
-usage: node foo.js [OPTIONS]
-options:
-    --version             Print tool version and exit.
-    -h, --help            Print this help and exit.
-    -v, --verbose         Verbose output. Use multiple times for more verbose.
-    -f FILE, --file=FILE  File to process
-
-$ node foo.js -v
-# opts: { verbose: [ true ],
-  _order: [ { name: 'verbose', value: true, from: 'argv' } ],
-  _args: [] }
-# args: []
-
-$ node foo.js --version arg1
-# opts: { version: true,
-  _order: [ { name: 'version', value: true, from: 'argv' } ],
-  _args: [ 'arg1' ] }
-# args: [ 'arg1' ]
-
-$ node foo.js -f bar.txt
-# opts: { file: 'bar.txt',
-  _order: [ { name: 'file', value: 'bar.txt', from: 'argv' } ],
-  _args: [] }
-# args: []
-
-$ node foo.js -vvv --file=blah
-# opts: { verbose: [ true, true, true ],
-  file: 'blah',
-  _order:
-   [ { name: 'verbose', value: true, from: 'argv' },
-     { name: 'verbose', value: true, from: 'argv' },
-     { name: 'verbose', value: true, from: 'argv' },
-     { name: 'file', value: 'blah', from: 'argv' } ],
-  _args: [] }
-# args: []
-```
-
-
-See the ["examples"](examples/) dir for a number of starter examples using
-some of dashdash's features.
-
-
-# Environment variable integration
-
-If you want to allow environment variables to specify options to your tool,
-dashdash makes this easy. We can change the 'verbose' option in the example
-above to include an 'env' field:
-
-```javascript
-    {
-        names: ['verbose', 'v'],
-        type: 'arrayOfBool',
-        env: 'FOO_VERBOSE',         // <--- add this line
-        help: 'Verbose output. Use multiple times for more verbose.'
-    },
-```
-
-then the **"FOO_VERBOSE" environment variable** can be used to set this
-option:
-
-```shell
-$ FOO_VERBOSE=1 node foo.js
-# opts: { verbose: [ true ],
-  _order: [ { name: 'verbose', value: true, from: 'env' } ],
-  _args: [] }
-# args: []
-```
-
-Boolean options will interpret the empty string as unset, '0' as false
-and anything else as true.
-
-```shell
-$ FOO_VERBOSE= node examples/foo.js                 # not set
-# opts: { _order: [], _args: [] }
-# args: []
-
-$ FOO_VERBOSE=0 node examples/foo.js                # '0' is false
-# opts: { verbose: [ false ],
-  _order: [ { key: 'verbose', value: false, from: 'env' } ],
-  _args: [] }
-# args: []
-
-$ FOO_VERBOSE=1 node examples/foo.js                # true
-# opts: { verbose: [ true ],
-  _order: [ { key: 'verbose', value: true, from: 'env' } ],
-  _args: [] }
-# args: []
-
-$ FOO_VERBOSE=boogabooga node examples/foo.js       # true
-# opts: { verbose: [ true ],
-  _order: [ { key: 'verbose', value: true, from: 'env' } ],
-  _args: [] }
-# args: []
-```
-
-Non-booleans can be used as well. Strings:
-
-```shell
-$ FOO_FILE=data.txt node examples/foo.js
-# opts: { file: 'data.txt',
-  _order: [ { key: 'file', value: 'data.txt', from: 'env' } ],
-  _args: [] }
-# args: []
-```
-
-Numbers:
-
-```shell
-$ FOO_TIMEOUT=5000 node examples/foo.js
-# opts: { timeout: 5000,
-  _order: [ { key: 'timeout', value: 5000, from: 'env' } ],
-  _args: [] }
-# args: []
-
-$ FOO_TIMEOUT=blarg node examples/foo.js
-foo: error: arg for "FOO_TIMEOUT" is not a positive integer: "blarg"
-```
-
-With the `includeEnv: true` config to `parser.help()` the environment
-variable can also be included in **help output**:
-
-    usage: node foo.js [OPTIONS]
-    options:
-        --version             Print tool version and exit.
-        -h, --help            Print this help and exit.
-        -v, --verbose         Verbose output. Use multiple times for more verbose.
-                              Environment: FOO_VERBOSE=1
-        -f FILE, --file=FILE  File to process
-
-
-# Bash completion
-
-Dashdash provides a simple way to create a Bash completion file that you
-can place in your "bash_completion.d" directory -- sometimes that is
-"/usr/local/etc/bash_completion.d/"). Features:
-
-- Support for short and long opts
-- Support for knowing which options take arguments
-- Support for subcommands (e.g. 'git log <TAB>' to show just options for the
-  log subcommand). See
-  [node-cmdln](https://github.com/trentm/node-cmdln#bash-completion) for
-  how to integrate that.
-- Does the right thing with "--" to stop options.
-- Custom optarg and arg types for custom completions.
-
-Dashdash will return bash completion file content given a parser instance:
-
-    var parser = dashdash.createParser({options: options});
-    console.log( parser.bashCompletion({name: 'mycli'}) );
-
-or directly from a `options` array of options specs:
-
-    var code = dashdash.bashCompletionFromOptions({
-        name: 'mycli',
-        options: OPTIONS
-    });
-
-Write that content to "/usr/local/etc/bash_completion.d/mycli" and you will
-have Bash completions for `mycli`. Alternatively you can write it to
-any file (e.g. "~/.bashrc") and source it.
-
-You could add a `--completion` hidden option to your tool that emits the
-completion content and document for your users to call that to install
-Bash completions.
-
-See [examples/ddcompletion.js](examples/ddcompletion.js) for a complete
-example, including how one can define bash functions for completion of custom
-option types. Also see [node-cmdln](https://github.com/trentm/node-cmdln) for
-how it uses this for Bash completion for full multi-subcommand tools.

-
-# Parser config
-
-Parser construction (i.e. `dashdash.createParser(CONFIG)`) takes the
-following fields:
-
-- `options` (Array of option specs). Required. See the
-  [Option specs](#option-specs) section below.
-
-- `interspersed` (Boolean). Optional. Default is true. If true this allows
-  interspersed arguments and options. I.e.:
-
-        node ./tool.js -v arg1 arg2 -h   # '-h' is after interspersed args
-
-  Set it to false to have '-h' **not** get parsed as an option in the above
-  example.
-
-- `allowUnknown` (Boolean).  Optional.  Default is false.  If false, this causes
-  unknown arguments to throw an error.  I.e.:
-
-        node ./tool.js -v arg1 --afe8asefksjefhas
-
-  Set it to true to treat the unknown option as a positional
-  argument.
-
-  **Caveat**: When a shortopt group, such as `-xaz` contains a mix of
-  known and unknown options, the *entire* group is passed through
-  unmolested as a positional argument.
-
-  Consider if you have a known short option `-a`, and parse the
-  following command line:
-
-        node ./tool.js -xaz
-
-  where `-x` and `-z` are unknown.  There are multiple ways to
-  interpret this:
-
-    1. `-x` takes a value: `{x: 'az'}`
-    2. `-x` and `-z` are both booleans: `{x:true,a:true,z:true}`
-
-  Since dashdash does not know what `-x` and `-z` are, it can't know
-  if you'd prefer to receive `{a:true,_args:['-x','-z']}` or
-  `{x:'az'}`, or `{_args:['-xaz']}`. Leaving the positional arg unprocessed
-  is the easiest mistake for the user to recover from.
-
-
-# Option specs
-
-Example using all fields (required fields are noted):
-
-```javascript
-{
-    names: ['file', 'f'],       // Required (one of `names` or `name`).
-    type: 'string',             // Required.
-    completionType: 'filename',
-    env: 'MYTOOL_FILE',
-    help: 'Config file to load before running "mytool"',
-    helpArg: 'PATH',
-    helpWrap: false,
-    default: path.resolve(process.env.HOME, '.mytoolrc')
-}
-```
-
-Each option spec in the `options` array must/can have the following fields:
-
-- `name` (String) or `names` (Array). Required. These give the option name
-  and aliases. The first name (if more than one given) is the key for the
-  parsed `opts` object.
-
-- `type` (String). Required. One of:
-
-    - bool
-    - string
-    - number
-    - integer
-    - positiveInteger
-    - date (epoch seconds, e.g. 1396031701, or ISO 8601 format
-      `YYYY-MM-DD[THH:MM:SS[.sss][Z]]`, e.g. "2014-03-28T18:35:01.489Z")
-    - arrayOfBool
-    - arrayOfString
-    - arrayOfNumber
-    - arrayOfInteger
-    - arrayOfPositiveInteger
-    - arrayOfDate
-
-  FWIW, these names attempt to match with asserts on
-  [assert-plus](https://github.com/mcavage/node-assert-plus).
-  You can add your own custom option types with `dashdash.addOptionType`.
-  See below.
-
-- `completionType` (String). Optional. This is used for [Bash
-  completion](#bash-completion) for an option argument. If not specified,
-  then the value of `type` is used. Any string may be specified, but only the
-  following values have meaning:
-
-    - `none`: Provide no completions.
-    - `file`: Bash's default completion (i.e. `complete -o default`), which
-      includes filenames.
-    - *Any string FOO for which a `function complete_FOO` Bash function is
-      defined.* This is for custom completions for a given tool. Typically
-      these custom functions are provided in the `specExtra` argument to
-      `dashdash.bashCompletionFromOptions()`. See
-      ["examples/ddcompletion.js"](examples/ddcompletion.js) for an example.
-
-- `env` (String or Array of String). Optional. An environment variable name
-  (or names) that can be used as a fallback for this option. For example,
-  given a "foo.js" like this:
-
-        var options = [{names: ['dry-run', 'n'], env: 'FOO_DRY_RUN'}];
-        var opts = dashdash.parse({options: options});
-
-  Both `node foo.js --dry-run` and `FOO_DRY_RUN=1 node foo.js` would result
-  in `opts.dry_run = true`.
-
-  An environment variable is only used as a fallback, i.e. it is ignored if
-  the associated option is given in `argv`.
-
-- `help` (String). Optional. Used for `parser.help()` output.
-
-- `helpArg` (String). Optional. Used in help output as the placeholder for
-  the option argument, e.g. the "PATH" in:
-
-        ...
-        -f PATH, --file=PATH    File to process
-        ...
-
-- `helpWrap` (Boolean). Optional, default true. Set this to `false` to have
-  that option's `help` *not* be text wrapped in `<parser>.help()` output.
-
-- `default`. Optional. A default value used for this option, if the
-  option isn't specified in argv.
-
-- `hidden` (Boolean). Optional, default false. If true, help output will not
-  include this option. See also the `includeHidden` option to
-  `bashCompletionFromOptions()` for [Bash completion](#bash-completion).
-
-
-# Option group headings
-
-You can add headings between option specs in the `options` array.  To do so,
-simply add an object with only a `group` property -- the string to print as
-the heading for the subsequent options in the array.  For example:
-
-```javascript
-var options = [
-    {
-        group: 'Armament Options'
-    },
-    {
-        names: [ 'weapon', 'w' ],
-        type: 'string'
-    },
-    {
-        group: 'General Options'
-    },
-    {
-        names: [ 'help', 'h' ],
-        type: 'bool'
-    }
-];
-...
-```
-
-Note: You can use an empty string, `{group: ''}`, to get a blank line in help
-output between groups of options.
-
-
-# Help config
-
-The `parser.help(...)` function is configurable as follows:
-
-        Options:
-          Armament Options:
-        ^^  -w WEAPON, --weapon=WEAPON  Weapon with which to crush. One of: |
-       /                                sword, spear, maul                  |
-      /   General Options:                                                  |
-     /      -h, --help                  Print this help and exit.           |
-    /   ^^^^                            ^                                   |
-    \       `-- indent                   `-- helpCol              maxCol ---'
-     `-- headingIndent
-
-- `indent` (Number or String). Default 4. Set to a number (for that many
-  spaces) or a string for the literal indent.
-- `headingIndent` (Number or String). Default half length of `indent`. Set to
-  a number (for that many spaces) or a string for the literal indent. This
-  indent applies to group heading lines, between normal option lines.
-- `nameSort` (String). Default is 'length'. By default the names are
-  sorted to put the short opts first (i.e. '-h, --help' preferred
-  to '--help, -h'). Set to 'none' to not do this sorting.
-- `maxCol` (Number). Default 80. Note that reflow is just done on whitespace
-  so a long token in the option help can overflow maxCol.
-- `helpCol` (Number). If not set a reasonable value will be determined
-  between `minHelpCol` and `maxHelpCol`.
-- `minHelpCol` (Number). Default 20.
-- `maxHelpCol` (Number). Default 40.
-- `helpWrap` (Boolean). Default true. Set to `false` to have option `help`
-  strings *not* be textwrapped to the helpCol..maxCol range.
-- `includeEnv` (Boolean). Default false. If the option has associated
-  environment variables (via the `env` option spec attribute), then
-  append mentioned of those envvars to the help string.
-- `includeDefault` (Boolean). Default false. If the option has a default value
-  (via the `default` option spec attribute, or a default on the option's type),
-  then a "Default: VALUE" string will be appended to the help string.

-# Custom option types
-
-Dashdash includes a good starter set of option types that it will parse for
-you. However, you can add your own via:
-
-    var dashdash = require('dashdash');
-    dashdash.addOptionType({
-        name: '...',
-        takesArg: true,
-        helpArg: '...',
-        parseArg: function (option, optstr, arg) {
-            ...
-        },
-        array: false,  // optional
-        arrayFlatten: false,  // optional
-        default: ...,   // optional
-        completionType: ...  // optional
-    });
-
-For example, a simple option type that accepts 'yes', 'y', 'no' or 'n' as
-a boolean argument would look like:
-
-    var dashdash = require('dashdash');
-
-    function parseYesNo(option, optstr, arg) {
-        var argLower = arg.toLowerCase()
-        if (~['yes', 'y'].indexOf(argLower)) {
-            return true;
-        } else if (~['no', 'n'].indexOf(argLower)) {
-            return false;
-        } else {
-            throw new Error(format(
-                'arg for "%s" is not "yes" or "no": "%s"',
-                optstr, arg));
-        }
-    }
-
-    dashdash.addOptionType({
-        name: 'yesno'
-        takesArg: true,
-        helpArg: '<yes|no>',
-        parseArg: parseYesNo
-    });
-
-    var options = {
-        {names: ['answer', 'a'], type: 'yesno'}
-    };
-    var opts = dashdash.parse({options: options});

-# Why
-
-Why another node.js option parsing lib?
-
-- `nopt` really is just for "tools like npm". Implicit opts (e.g. '--no-foo'
-  works for every '--foo'). Can't disable abbreviated opts. Can't do multiple
-  usages of same opt, e.g. '-vvv' (I think). Can't do grouped short opts.
-
-- `optimist` has surprise interpretation of options (at least to me).
-  Implicit opts mean ambiguities and poor error handling for fat-fingering.
-  `process.exit` calls makes it hard to use as a libary.
-
-- `optparse` Incomplete docs. Is this an attempted clone of Python's `optparse`.
-  Not clear. Some divergence. `parser.on("name", ...)` API is weird.
-
-- `argparse` Dep on underscore. No thanks just for option processing.
-  `find lib | wc -l` -> `26`. Overkill.
-  Argparse is a bit different anyway. Not sure I want that.
-
-- `posix-getopt` No type validation. Though that isn't a killer. AFAIK can't
-  have a long opt without a short alias. I.e. no `getopt_long` semantics.
-  Also, no whizbang features like generated help output.
-
-- ["commander.js"](https://github.com/visionmedia/commander.js): I wrote
-  [a critique](http://trentm.com/2014/01/a-critique-of-commander-for-nodejs.html)
-  a while back. It seems fine, but last I checked had
-  [an outstanding bug](https://github.com/visionmedia/commander.js/pull/121)
-  that would prevent me from using it.

-#
-# A generic Bash completion driver script.
-#
-# This is meant to provide a re-usable chunk of Bash to use for
-# "etc/bash_completion.d/" files for individual tools. Only the "Configuration"
-# section with tool-specific info need differ. Features:
-#
-# - support for short and long opts
-# - support for knowing which options take arguments
-# - support for subcommands (e.g. 'git log <TAB>' to show just options for the
-#   log subcommand)
-# - does the right thing with "--" to stop options
-# - custom optarg and arg types for custom completions
-# - (TODO) support for shells other than Bash (tcsh, zsh, fish?, etc.)
-#
-#
-# Examples/design:
-#
-# 1. Bash "default" completion. By default Bash's 'complete -o default' is
-#    enabled. That means when there are no completions (e.g. if no opts match
-#    the current word), then you'll get Bash's default completion. Most notably
-#    that means you get filename completion. E.g.:
-#       $ tool ./<TAB>
-#       $ tool READ<TAB>
-#
-# 2. all opts and subcmds:
-#       $ tool <TAB>
-#       $ tool -v <TAB>     # assuming '-v' doesn't take an arg
-#       $ tool -<TAB>       # matching opts
-#       $ git lo<TAB>       # matching subcmds
-#
-#    Long opt completions are given *without* the '=', i.e. we prefer space
-#    separated because that's easier for good completions.
-#
-# 3. long opt arg with '='
-#       $ tool --file=<TAB>
-#       $ tool --file=./d<TAB>
-#    We maintain the "--file=" prefix. Limitation: With the attached prefix
-#    the 'complete -o filenames' doesn't know to do dirname '/' suffixing. Meh.
-#
-# 4. envvars:
-#       $ tool $<TAB>
-#       $ tool $P<TAB>
-#    Limitation: Currently only getting exported vars, so we miss "PS1" and
-#    others.
-#
-# 5. Defer to other completion in a subshell:
-#       $ tool --file $(cat ./<TAB>
-#    We get this from 'complete -o default ...'.
-#
-# 6. Custom completion types from a provided bash function.
-#       $ tool --profile <TAB>        # complete available "profiles"

- *
- * @param config {Object} Config for controlling the option help output.
- *      - indent {Number|String} Default 4. An indent/prefix to use for

- *      - minHelpCol {Number} Default 20.

-# delayed-stream
-
-Buffers events from a stream until you are ready to handle them.
-
-## Installation
-
-``` bash
-npm install delayed-stream
-```
-
-## Usage
-
-The following example shows how to write a http echo server that delays its
-response by 1000 ms.
-
-``` javascript
-var DelayedStream = require('delayed-stream');
-var http = require('http');
-
-http.createServer(function(req, res) {
-  var delayed = DelayedStream.create(req);
-
-  setTimeout(function() {
-    res.writeHead(200);
-    delayed.pipe(res);
-  }, 1000);
-});
-```
-
-If you are not using `Stream#pipe`, you can also manually release the buffered
-events by calling `delayedStream.resume()`:
-
-``` javascript
-var delayed = DelayedStream.create(req);
-
-setTimeout(function() {
-  // Emit all buffered events and resume underlaying source
-  delayed.resume();
-}, 1000);
-```
-
-## Implementation
-
-In order to use this meta stream properly, here are a few things you should
-know about the implementation.
-
-### Event Buffering / Proxying
-
-All events of the `source` stream are hijacked by overwriting the `source.emit`
-method. Until node implements a catch-all event listener, this is the only way.
-
-However, delayed-stream still continues to emit all events it captures on the
-`source`, regardless of whether you have released the delayed stream yet or
-not.
-
-Upon creation, delayed-stream captures all `source` events and stores them in
-an internal event buffer. Once `delayedStream.release()` is called, all
-buffered events are emitted on the `delayedStream`, and the event buffer is
-cleared. After that, delayed-stream merely acts as a proxy for the underlaying
-source.
-
-### Error handling
-
-Error events on `source` are buffered / proxied just like any other events.
-However, `delayedStream.create` attaches a no-op `'error'` listener to the
-`source`. This way you only have to handle errors on the `delayedStream`
-object, rather than in two places.
-
-### Buffer limits
-
-delayed-stream provides a `maxDataSize` property that can be used to limit
-the amount of data being buffered. In order to protect you from bad `source`
-streams that don't react to `source.pause()`, this feature is enabled by
-default.
-
-## API
-
-### DelayedStream.create(source, [options])
-
-Returns a new `delayedStream`. Available options are:
-
-* `pauseStream`
-* `maxDataSize`
-
-The description for those properties can be found below.
-
-### delayedStream.source
-
-The `source` stream managed by this object. This is useful if you are
-passing your `delayedStream` around, and you still want to access properties
-on the `source` object.
-
-### delayedStream.pauseStream = true
-
-Whether to pause the underlaying `source` when calling
-`DelayedStream.create()`. Modifying this property afterwards has no effect.
-
-### delayedStream.maxDataSize = 1024 * 1024
-
-The amount of data to buffer before emitting an `error`.
-
-If the underlaying source is emitting `Buffer` objects, the `maxDataSize`
-refers to bytes.
-
-If the underlaying source is emitting JavaScript strings, the size refers to
-characters.
-
-If you know what you are doing, you can set this property to `Infinity` to
-disable this feature. You can also modify this property during runtime.
-
-### delayedStream.dataSize = 0
-
-The amount of data buffered so far.
-
-### delayedStream.readable
-
-An ECMA5 getter that returns the value of `source.readable`.
-
-### delayedStream.resume()
-
-If the `delayedStream` has not been released so far, `delayedStream.release()`
-is called.
-
-In either case, `source.resume()` is called.
-
-### delayedStream.pause()
-
-Calls `source.pause()`.
-
-### delayedStream.pipe(dest)
-
-Calls `delayedStream.resume()` and then proxies the arguments to `source.pipe`.
-
-### delayedStream.release()
-
-Emits and clears all events that have been buffered up so far. This does not
-resume the underlaying source, use `delayedStream.resume()` instead.

-# delegates
-
-  Node method and accessor delegation utilty.
-
-## Installation
-
-```
-$ npm install delegates
-```
-
-## Example
-
-```js
-var delegate = require('delegates');
-
-...
-
-delegate(proto, 'request')
-  .method('acceptsLanguages')
-  .method('acceptsEncodings')
-  .method('acceptsCharsets')
-  .method('accepts')
-  .method('is')
-  .access('querystring')
-  .access('idempotent')
-  .access('socket')
-  .access('length')
-  .access('query')
-  .access('search')
-  .access('status')
-  .access('method')
-  .access('path')
-  .access('body')
-  .access('host')
-  .access('url')
-  .getter('subdomains')
-  .getter('protocol')
-  .getter('header')
-  .getter('stale')
-  .getter('fresh')
-  .getter('secure')
-  .getter('ips')
-  .getter('ip')
-```
-
-# API
-
-## Delegate(proto, prop)
-
-Creates a delegator instance used to configure using the `prop` on the given
-`proto` object. (which is usually a prototype)
-
-## Delegate#method(name)
-
-Allows the given method `name` to be accessed on the host.
-
-## Delegate#getter(name)
-
-Creates a "getter" for the property with the given `name` on the delegated
-object.
-
-## Delegate#setter(name)
-
-Creates a "setter" for the property with the given `name` on the delegated
-object.
-
-## Delegate#access(name)
-
-Creates an "accessor" (ie: both getter *and* setter) for the property with the
-given `name` on the delegated object.
-
-## Delegate#fluent(name)
-
-A unique type of "accessor" that works for a "fluent" API. When called as a
-getter, the method returns the expected value. However, if the method is called
-with a value, it will return itself so it can be chained. For example:
-
-```js
-delegate(proto, 'request')
-  .fluent('query')
-
-// getter
-var q = request.query();
-
-// setter (chainable)
-request
-  .query({ a: 1 })
-  .query({ b: 2 });
-```

-========
-
-ECC package based on [jsbn](https://github.com/andyperlitch/jsbn) from [Tom Wu](http://www-cs-students.stanford.edu/~tjw/).
-
-This is a subset of the same interface as the [node compiled module](https://github.com/quartzjer/ecc), but works in the browser too.
-
-Also uses point compression now from [https://github.com/kaielvin](https://github.com/kaielvin/jsbn-ec-point-compression).

-# Makefile.targ: common targets.
-#
-# NOTE: This makefile comes from the "eng" repo. It's designed to be dropped
-# into other repos as-is without requiring any modifications. If you find
-# yourself changing this file, you should instead update the original copy in
-# eng.git and then update your repo to use the new version.
-#
-# This Makefile defines several useful targets and rules. You can use it by
-# including it from a Makefile that specifies some of the variables below.
-#
-# Targets defined in this Makefile:
-#
-#	check	Checks JavaScript files for lint and style
-#		Checks bash scripts for syntax
-#		Checks SMF manifests for validity against the SMF DTD
-#
-#	clean	Removes built files
-#
-#	docs	Builds restdown documentation in docs/
-#
-#	prepush	Depends on "check" and "test"
-#
-#	test	Does nothing (you should override this)
-#
-#	xref	Generates cscope (source cross-reference index)
-#
-# For details on what these targets are supposed to do, see the Joyent
-# Engineering Guide.
-#
-# To make use of these targets, you'll need to set some of these variables. Any
-# variables left unset will simply not be used.
-#
-#	BASH_FILES	Bash scripts to check for syntax
-#			(paths relative to top-level Makefile)
-#
-#	CLEAN_FILES	Files to remove as part of the "clean" target.  Note
-#			that files generated by targets in this Makefile are
-#			automatically included in CLEAN_FILES.  These include
-#			restdown-generated HTML and JSON files.
-#
-#	DOC_FILES	Restdown (documentation source) files. These are
-#			assumed to be contained in "docs/", and must NOT
-#			contain the "docs/" prefix.
-#
-#	JSL_CONF_NODE	Specify JavaScriptLint configuration files
-#	JSL_CONF_WEB	(paths relative to top-level Makefile)
-#
-#			Node.js and Web configuration files are separate
-#			because you'll usually want different global variable
-#			configurations.  If no file is specified, none is given
-#			to jsl, which causes it to use a default configuration,
-#			which probably isn't what you want.
-#
-#	JSL_FILES_NODE	JavaScript files to check with Node config file.
-#	JSL_FILES_WEB	JavaScript files to check with Web config file.
-#
-# You can also override these variables:
-#
-#	BASH		Path to bash (default: bash)
-#
-#	CSCOPE_DIRS	Directories to search for source files for the cscope
-#			index. (default: ".")
-#
-#	JSL		Path to JavaScriptLint (default: "jsl")
-#
-#	JSL_FLAGS_NODE	Additional flags to pass through to JSL
-#	JSL_FLAGS_WEB
-#	JSL_FLAGS
-#
-#	JSSTYLE		Path to jsstyle (default: jsstyle)
-#
-#	JSSTYLE_FLAGS	Additional flags to pass through to jsstyle
-#

-#
-# Defaults for the various tools we use.

-# Targets. For descriptions on what these are supposed to do, see the
-# Joyent Engineering Guide.
-#
-
-#
-# Instruct make to keep around temporary files. We have rules below that
-# automatically update git submodules as needed, but they employ a deps/*/.git
-# temporary file. Without this directive, make tries to remove these .git
-# directories after the build has completed.
-#
-.SECONDARY: $($(wildcard deps/*):%=%/.git)
-
-#
-# This rule enables other rules that use files from a git submodule to have
-# those files depend on deps/module/.git and have "make" automatically check
-# out the submodule as needed.
-#
-deps/%/.git:
-	git submodule update --init deps/$*
-
-#
-# These recipes make heavy use of dynamically-created phony targets. The parent
-# Makefile defines a list of input files like BASH_FILES. We then say that each
-# of these files depends on a fake target called filename.bashchk, and then we
-# define a pattern rule for those targets that runs bash in check-syntax-only
-# mode. This mechanism has the nice properties that if you specify zero files,
-# the rule becomes a noop (unlike a single rule to check all bash files, which
-# would invoke bash with zero files), and you can check individual files from
-# the command line with "make filename.bashchk".

-#        including files that will override same-named files provided by
-#        restdown.

-# extsprintf: extended POSIX-style sprintf
-
-Stripped down version of s[n]printf(3c).  We make a best effort to throw an
-exception when given a format string we don't understand, rather than ignoring
-it, so that we won't break existing programs if/when we go implement the rest
-of this.
-
-This implementation currently supports specifying
-
-* field alignment ('-' flag),
-* zero-pad ('0' flag)
-* always show numeric sign ('+' flag),
-* field width
-* conversions for strings, decimal integers, and floats (numbers).
-* argument size specifiers.  These are all accepted but ignored, since
-  Javascript has no notion of the physical size of an argument.
-
-Everything else is currently unsupported, most notably: precision, unsigned
-numbers, non-decimal numbers, and characters.
-
-Besides the usual POSIX conversions, this implementation supports:
-
-* `%j`: pretty-print a JSON object (using node's "inspect")
-* `%r`: pretty-print an Error object
-
-# Example
-
-First, install it:
-
-    # npm install extsprintf
-
-Now, use it:
-
-    var mod_extsprintf = require('extsprintf');
-    console.log(mod_extsprintf.sprintf('hello %25s', 'world'));
-
-outputs:
-
-    hello                     world
-
-# Also supported
-
-**printf**: same args as sprintf, but prints the result to stdout
-
-**fprintf**: same args as sprintf, preceded by a Node stream.  Prints the result
-to the given stream.

-### Output format
-# Customize the format of the error message.
-#    __FILE__ indicates current file path
-#    __FILENAME__ indicates current file name
-#    __LINE__ indicates current line
-#    __COL__ indicates current column
-#    __ERROR__ indicates error message (__ERROR_PREFIX__: __ERROR_MSG__)
-#    __ERROR_NAME__ indicates error name (used in configuration file)
-#    __ERROR_PREFIX__ indicates error prefix
-#    __ERROR_MSG__ indicates error message
-#
-# For machine-friendly output, the output format can be prefixed with
-# "encode:". If specified, all items will be encoded with C-slashes.
-#
-# Visual Studio syntax (default):
-+output-format __FILE__(__LINE__): __ERROR__
-# Alternative syntax:
-#+output-format __FILE__:__LINE__: __ERROR__
-
-
-### Context
-# Show the in-line position of the error.
-# Use "+context" to display or "-context" to suppress.
-#
-+context
-
-
-### Control Comments
-# Both JavaScript Lint and the JScript interpreter confuse each other with the syntax for
-# the /*@keyword@*/ control comments and JScript conditional comments. (The latter is
-# enabled in JScript with @cc_on@). The /*jsl:keyword*/ syntax is preferred for this reason,
-# although legacy control comments are enabled by default for backward compatibility.
-#
--legacy_control_comments
-
-
-### Defining identifiers
-# By default, "option explicit" is enabled on a per-file basis.
-# To enable this for all files, use "+always_use_option_explicit"
--always_use_option_explicit
-
-# Define certain identifiers of which the lint is not aware.
-# (Use this in conjunction with the "undeclared identifier" warning.)
-#
-# Common uses for webpages might be:
-+define __dirname
-+define clearInterval
-+define clearTimeout
-+define console
-+define exports
-+define global
-+define process
-+define require
-+define setInterval
-+define setTimeout
-+define Buffer
-+define JSON
-+define Math
-
-### JavaScript Version
-# To change the default JavaScript version:
-#+default-type text/javascript;version=1.5
-#+default-type text/javascript;e4x=1
-
-### Files
-# Specify which files to lint
-# Use "+recurse" to enable recursion (disabled by default).
-# To add a set of files, use "+process FileName", "+process Folder\Path\*.js",
-# or "+process Folder\Path\*.htm".

-# fast-deep-equal
-The fastest deep equal with ES6 Map, Set and Typed arrays support.
-
-[![Build Status](https://travis-ci.org/epoberezkin/fast-deep-equal.svg?branch=master)](https://travis-ci.org/epoberezkin/fast-deep-equal)
-[![npm](https://img.shields.io/npm/v/fast-deep-equal.svg)](https://www.npmjs.com/package/fast-deep-equal)
-[![Coverage Status](https://coveralls.io/repos/github/epoberezkin/fast-deep-equal/badge.svg?branch=master)](https://coveralls.io/github/epoberezkin/fast-deep-equal?branch=master)
-
-
-## Install
-
-```bash
-npm install fast-deep-equal
-```
-
-
-## Features
-
-- ES5 compatible
-- works in node.js (8+) and browsers (IE9+)
-- checks equality of Date and RegExp objects by value.
-
-ES6 equal (`require('fast-deep-equal/es6')`) also supports:
-- Maps
-- Sets
-- Typed arrays
-
-
-## Usage
-
-```javascript
-var equal = require('fast-deep-equal');
-console.log(equal({foo: 'bar'}, {foo: 'bar'})); // true
-```
-
-To support ES6 Maps, Sets and Typed arrays equality use:
-
-```javascript
-var equal = require('fast-deep-equal/es6');
-console.log(equal(Int16Array([1, 2]), Int16Array([1, 2]))); // true
-```
-
-To use with React (avoiding the traversal of React elements' _owner
-property that contains circular references and is not needed when
-comparing the elements - borrowed from [react-fast-compare](https://github.com/FormidableLabs/react-fast-compare)):
-
-```javascript
-var equal = require('fast-deep-equal/react');
-var equal = require('fast-deep-equal/es6/react');
-```
-
-
-## Performance benchmark
-
-Node.js v12.6.0:
-
-```
-fast-deep-equal x 261,950 ops/sec ±0.52% (89 runs sampled)
-fast-deep-equal/es6 x 212,991 ops/sec ±0.34% (92 runs sampled)
-fast-equals x 230,957 ops/sec ±0.83% (85 runs sampled)
-nano-equal x 187,995 ops/sec ±0.53% (88 runs sampled)
-shallow-equal-fuzzy x 138,302 ops/sec ±0.49% (90 runs sampled)
-underscore.isEqual x 74,423 ops/sec ±0.38% (89 runs sampled)
-lodash.isEqual x 36,637 ops/sec ±0.72% (90 runs sampled)
-deep-equal x 2,310 ops/sec ±0.37% (90 runs sampled)
-deep-eql x 35,312 ops/sec ±0.67% (91 runs sampled)
-ramda.equals x 12,054 ops/sec ±0.40% (91 runs sampled)
-util.isDeepStrictEqual x 46,440 ops/sec ±0.43% (90 runs sampled)
-assert.deepStrictEqual x 456 ops/sec ±0.71% (88 runs sampled)
-
-The fastest is fast-deep-equal
-```
-
-To run benchmark (requires node.js 6+):
-
-```bash
-npm run benchmark
-```
-
-__Please note__: this benchmark runs against the available test cases. To choose the most performant library for your application, it is recommended to benchmark against your data and to NOT expect this benchmark to reflect the performance difference in your application.

-# fast-json-stable-stringify
-
-Deterministic `JSON.stringify()` - a faster version of [@substack](https://github.com/substack)'s json-stable-strigify without [jsonify](https://github.com/substack/jsonify).
-
-You can also pass in a custom comparison function.
-
-[![Build Status](https://travis-ci.org/epoberezkin/fast-json-stable-stringify.svg?branch=master)](https://travis-ci.org/epoberezkin/fast-json-stable-stringify)
-[![Coverage Status](https://coveralls.io/repos/github/epoberezkin/fast-json-stable-stringify/badge.svg?branch=master)](https://coveralls.io/github/epoberezkin/fast-json-stable-stringify?branch=master)
-
-# example
-
-``` js
-var stringify = require('fast-json-stable-stringify');
-var obj = { c: 8, b: [{z:6,y:5,x:4},7], a: 3 };
-console.log(stringify(obj));
-```
-
-output:
-
-```
-{"a":3,"b":[{"x":4,"y":5,"z":6},7],"c":8}
-```
-
-
-# methods
-
-``` js
-var stringify = require('fast-json-stable-stringify')
-```
-
-## var str = stringify(obj, opts)
-
-Return a deterministic stringified string `str` from the object `obj`.
-
-
-## options
-
-### cmp
-
-If `opts` is given, you can supply an `opts.cmp` to have a custom comparison
-function for object keys. Your function `opts.cmp` is called with these
-parameters:
-
-``` js
-opts.cmp({ key: akey, value: avalue }, { key: bkey, value: bvalue })
-```
-
-For example, to sort on the object key names in reverse order you could write:
-
-``` js
-var stringify = require('fast-json-stable-stringify');
-
-var obj = { c: 8, b: [{z:6,y:5,x:4},7], a: 3 };
-var s = stringify(obj, function (a, b) {
-    return a.key < b.key ? 1 : -1;
-});
-console.log(s);
-```
-
-which results in the output string:
-
-```
-{"c":8,"b":[{"z":6,"y":5,"x":4},7],"a":3}
-```
-
-Or if you wanted to sort on the object values in reverse order, you could write:
-
-```
-var stringify = require('fast-json-stable-stringify');
-
-var obj = { d: 6, c: 5, b: [{z:3,y:2,x:1},9], a: 10 };
-var s = stringify(obj, function (a, b) {
-    return a.value < b.value ? 1 : -1;
-});
-console.log(s);
-```
-
-which outputs:
-
-```
-{"d":6,"c":5,"b":[{"z":3,"y":2,"x":1},9],"a":10}
-```
-
-### cycles
-
-Pass `true` in `opts.cycles` to stringify circular property as `__cycle__` - the result will not be a valid JSON string in this case.
-
-TypeError will be thrown in case of circular object without this option.
-
-
-# install
-
-With [npm](https://npmjs.org) do:
-
-```
-npm install fast-json-stable-stringify
-```
-
-
-# benchmark
-
-To run benchmark (requires Node.js 6+):
-```
-node benchmark
-```
-
-Results:
-```
-fast-json-stable-stringify x 17,189 ops/sec ±1.43% (83 runs sampled)
-json-stable-stringify x 13,634 ops/sec ±1.39% (85 runs sampled)
-fast-stable-stringify x 20,212 ops/sec ±1.20% (84 runs sampled)
-faster-stable-stringify x 15,549 ops/sec ±1.12% (84 runs sampled)
-The fastest is fast-stable-stringify
-```

-## Install
-
-```
-npm install --save form-data
-```
-
-## Usage
-
-In this example we are constructing a form with 3 fields that contain a string,
-a buffer and a file stream.
-
-``` javascript
-var FormData = require('form-data');
-var fs = require('fs');
-
-var form = new FormData();
-form.append('my_field', 'my value');
-form.append('my_buffer', new Buffer(10));
-form.append('my_file', fs.createReadStream('/foo/bar.jpg'));
-```
-
-Also you can use http-response stream:
-
-``` javascript
-var FormData = require('form-data');
-var http = require('http');
-
-var form = new FormData();
-
-http.request('http://nodejs.org/images/logo.png', function(response) {
-  form.append('my_field', 'my value');
-  form.append('my_buffer', new Buffer(10));
-  form.append('my_logo', response);
-});
-```
-
-Or @mikeal's [request](https://github.com/request/request) stream:
-
-``` javascript
-var FormData = require('form-data');
-var request = require('request');
-
-var form = new FormData();
-
-form.append('my_field', 'my value');
-form.append('my_buffer', new Buffer(10));
-form.append('my_logo', request('http://nodejs.org/images/logo.png'));
-```
-
-In order to submit this form to a web application, call ```submit(url, [callback])``` method:
-
-``` javascript
-form.submit('http://example.org/', function(err, res) {
-  // res – response object (http.IncomingMessage)  //
-  res.resume();
-});
-
-```
-
-For more advanced request manipulations ```submit()``` method returns ```http.ClientRequest``` object, or you can choose from one of the alternative submission methods.
-
-### Custom options
-
-You can provide custom options, such as `maxDataSize`:
-
-``` javascript
-var FormData = require('form-data');
-
-var form = new FormData({ maxDataSize: 20971520 });
-form.append('my_field', 'my value');
-form.append('my_buffer', /* something big */);
-```
-
-List of available options could be found in [combined-stream](https://github.com/felixge/node-combined-stream/blob/master/lib/combined_stream.js#L7-L15)
-
-### Alternative submission methods
-
-You can use node's http client interface:
-
-``` javascript
-var http = require('http');
-
-var request = http.request({
-  method: 'post',
-  host: 'example.org',
-  path: '/upload',
-  headers: form.getHeaders()
-});
-
-form.pipe(request);
-
-request.on('response', function(res) {
-  console.log(res.statusCode);
-});
-```
-
-Or if you would prefer the `'Content-Length'` header to be set for you:
-
-``` javascript
-form.submit('example.org/upload', function(err, res) {
-  console.log(res.statusCode);
-});
-```
-
-To use custom headers and pre-known length in parts:
-
-``` javascript
-var CRLF = '\r\n';
-var form = new FormData();
-
-var options = {
-  header: CRLF + '--' + form.getBoundary() + CRLF + 'X-Custom-Header: 123' + CRLF + CRLF,
-  knownLength: 1
-};
-
-form.append('my_buffer', buffer, options);
-
-form.submit('http://example.com/', function(err, res) {
-  if (err) throw err;
-  console.log('Done');
-});
-```
-
-Form-Data can recognize and fetch all the required information from common types of streams (```fs.readStream```, ```http.response``` and ```mikeal's request```), for some other types of streams you'd need to provide "file"-related information manually:
-
-``` javascript
-someModule.stream(function(err, stdout, stderr) {
-  if (err) throw err;
-
-  var form = new FormData();
-
-  form.append('file', stdout, {
-    filename: 'unicycle.jpg', // ... or:
-    filepath: 'photos/toys/unicycle.jpg',
-    contentType: 'image/jpeg',
-    knownLength: 19806
-  });
-
-  form.submit('http://example.com/', function(err, res) {
-    if (err) throw err;
-    console.log('Done');
-  });
-});
-```
-
-The `filepath` property overrides `filename` and may contain a relative path. This is typically used when uploading [multiple files from a directory](https://wicg.github.io/entries-api/#dom-htmlinputelement-webkitdirectory).
-
-For edge cases, like POST request to URL with query string or to pass HTTP auth credentials, object can be passed to `form.submit()` as first parameter:
-
-``` javascript
-form.submit({
-  host: 'example.com',
-  path: '/probably.php?extra=params',
-  auth: 'username:password'
-}, function(err, res) {
-  console.log(res.statusCode);
-});
-```
-
-In case you need to also send custom HTTP headers with the POST request, you can use the `headers` key in first parameter of `form.submit()`:
-
-``` javascript
-form.submit({
-  host: 'example.com',
-  path: '/surelynot.php',
-  headers: {'x-test-header': 'test-header-value'}
-}, function(err, res) {
-  console.log(res.statusCode);
-});
-```
-
-### Integration with other libraries
-
-#### Request
-
-Form submission using  [request](https://github.com/request/request):
-
-```javascript
-var formData = {
-  my_field: 'my_value',
-  my_file: fs.createReadStream(__dirname + '/unicycle.jpg'),
-};
-
-request.post({url:'http://service.com/upload', formData: formData}, function(err, httpResponse, body) {
-  if (err) {
-    return console.error('upload failed:', err);
-  }
-  console.log('Upload successful!  Server responded with:', body);
-});
-```
-
-For more details see [request readme](https://github.com/request/request#multipartform-data-multipart-form-uploads).
-
-#### node-fetch
-
-You can also submit a form using [node-fetch](https://github.com/bitinn/node-fetch):
-
-```javascript
-var form = new FormData();
-
-form.append('a', 1);
-
-fetch('http://example.com', { method: 'POST', body: form })
-    .then(function(res) {
-        return res.json();
-    }).then(function(json) {
-        console.log(json);
-    });
-```
-
-## Notes
-
-- ```getLengthSync()``` method DOESN'T calculate length for streams, use ```knownLength``` options as workaround.
-- Starting version `2.x` FormData has dropped support for `node@0.10.x`.

-Like FS streams, but with stat on them, and supporting directories and
-symbolic links, as well as normal files.  Also, you can use this to set
-the stats on a file, even if you don't change its contents, or to create
-a symlink, etc.
-
-So, for example, you can "write" a directory, and it'll call `mkdir`.  You
-can specify a uid and gid, and it'll call `chown`.  You can specify a
-`mtime` and `atime`, and it'll call `utimes`.  You can call it a symlink
-and provide a `linkpath` and it'll call `symlink`.
-
-Note that it won't automatically resolve symbolic links.  So, if you
-call `fstream.Reader('/some/symlink')` then you'll get an object
-that stats and then ends immediately (since it has no data).  To follow
-symbolic links, do this: `fstream.Reader({path:'/some/symlink', follow:
-true })`.
-
-There are various checks to make sure that the bytes emitted are the
-same as the intended size, if the size is set.
-
-## Examples
-
-```javascript
-fstream
-  .Writer({ path: "path/to/file"
-          , mode: 0755
-          , size: 6
-          })
-  .write("hello\n")
-  .end()
-```
-
-This will create the directories if they're missing, and then write
-`hello\n` into the file, chmod it to 0755, and assert that 6 bytes have
-been written when it's done.
-
-```javascript
-fstream
-  .Writer({ path: "path/to/file"
-          , mode: 0755
-          , size: 6
-          , flags: "a"
-          })
-  .write("hello\n")
-  .end()
-```
-
-You can pass flags in, if you want to append to a file.
-
-```javascript
-fstream
-  .Writer({ path: "path/to/symlink"
-          , linkpath: "./file"
-          , SymbolicLink: true
-          , mode: "0755" // octal strings supported
-          })
-  .end()
-```
-
-If isSymbolicLink is a function, it'll be called, and if it returns
-true, then it'll treat it as a symlink.  If it's not a function, then
-any truish value will make a symlink, or you can set `type:
-'SymbolicLink'`, which does the same thing.
-
-Note that the linkpath is relative to the symbolic link location, not
-the parent dir or cwd.
-
-```javascript
-fstream
-  .Reader("path/to/dir")
-  .pipe(fstream.Writer("path/to/other/dir"))
-```
-
-This will do like `cp -Rp path/to/dir path/to/other/dir`.  If the other
-dir exists and isn't a directory, then it'll emit an error.  It'll also
-set the uid, gid, mode, etc. to be identical.  In this way, it's more
-like `rsync -a` than simply a copy.

-# graceful-fs
-
-graceful-fs functions as a drop-in replacement for the fs module,
-making various improvements.
-
-The improvements are meant to normalize behavior across different
-platforms and environments, and to make filesystem access more
-resilient to errors.
-
-## Improvements over [fs module](https://nodejs.org/api/fs.html)
-
-* Queues up `open` and `readdir` calls, and retries them once
-  something closes if there is an EMFILE error from too many file
-  descriptors.
-* fixes `lchmod` for Node versions prior to 0.6.2.
-* implements `fs.lutimes` if possible. Otherwise it becomes a noop.
-* ignores `EINVAL` and `EPERM` errors in `chown`, `fchown` or
-  `lchown` if the user isn't root.
-* makes `lchmod` and `lchown` become noops, if not available.
-* retries reading a file if `read` results in EAGAIN error.
-
-On Windows, it retries renaming a file for up to one second if `EACCESS`
-or `EPERM` error occurs, likely because antivirus software has locked
-the directory.
-
-## USAGE
-
-```javascript
-// use just like fs
-var fs = require('graceful-fs')
-
-// now go and do stuff with it...
-fs.readFileSync('some-file-or-whatever')
-```
-
-## Global Patching
-
-If you want to patch the global fs module (or any other fs-like
-module) you can do this:
-
-```javascript
-// Make sure to read the caveat below.
-var realFs = require('fs')
-var gracefulFs = require('graceful-fs')
-gracefulFs.gracefulify(realFs)
-```
-
-This should only ever be done at the top-level application layer, in
-order to delay on EMFILE errors from any fs-using dependencies.  You
-should **not** do this in a library, because it can cause unexpected
-delays in other parts of the program.
-
-## Changes
-
-This module is fairly stable at this point, and used by a lot of
-things.  That being said, because it implements a subtle behavior
-change in a core part of the node API, even modest changes can be
-extremely breaking, and the versioning is thus biased towards
-bumping the major when in doubt.
-
-The main change between major versions has been switching between
-providing a fully-patched `fs` module vs monkey-patching the node core
-builtin, and the approach by which a non-monkey-patched `fs` was
-created.
-
-The goal is to trade `EMFILE` errors for slower fs operations.  So, if
-you try to open a zillion files, rather than crashing, `open`
-operations will be queued up and wait for something else to `close`.
-
-There are advantages to each approach.  Monkey-patching the fs means
-that no `EMFILE` errors can possibly occur anywhere in your
-application, because everything is using the same core `fs` module,
-which is patched.  However, it can also obviously cause undesirable
-side-effects, especially if the module is loaded multiple times.
-
-Implementing a separate-but-identical patched `fs` module is more
-surgical (and doesn't run the risk of patching multiple times), but
-also imposes the challenge of keeping in sync with the core module.
-
-The current approach loads the `fs` module, and then creates a
-lookalike object that has all the same methods, except a few that are
-patched.  It is safe to use in all versions of Node from 0.8 through
-7.0.
-
-### v4
-
-* Do not monkey-patch the fs module.  This module may now be used as a
-  drop-in dep, and users can opt into monkey-patching the fs builtin
-  if their app requires it.
-
-### v3
-
-* Monkey-patch fs, because the eval approach no longer works on recent
-  node.
-* fixed possible type-error throw if rename fails on windows
-* verify that we *never* get EMFILE errors
-* Ignore ENOSYS from chmod/chown
-* clarify that graceful-fs must be used as a drop-in
-
-### v2.1.0
-
-* Use eval rather than monkey-patching fs.
-* readdir: Always sort the results
-* win32: requeue a file if error has an OK status
-
-### v2.0
-
-* A return to monkey patching
-* wrap process.cwd
-
-### v1.1
-
-* wrap readFile
-* Wrap fs.writeFile.
-* readdir protection
-* Don't clobber the fs builtin
-* Handle fs.read EAGAIN errors by trying again
-* Expose the curOpen counter
-* No-op lchown/lchmod if not implemented
-* fs.rename patch only for win32
-* Patch fs.rename to handle AV software on Windows
-* Close #4 Chown should not fail on einval or eperm if non-root
-* Fix isaacs/fstream#1 Only wrap fs one time
-* Fix #3 Start at 1024 max files, then back off on EMFILE
-* lutimes that doens't blow up on Linux
-* A full on-rewrite using a queue instead of just swallowing the EMFILE error
-* Wrap Read/Write streams as well
-
-### 1.0
-
-* Update engines for node 0.6
-* Be lstat-graceful on Windows
-* first

-### v2.7.4
-
-* Reset colors prior to ending a line, to eliminate flicker when a line
-  is trucated between start and end color sequences.
-
-### v2.7.3
-
-* Only create our onExit handler when we're enabled and remove it when we're
-  disabled.  This stops us from creating multiple onExit handlers when
-  multiple gauge objects are being used.
-* Fix bug where if a theme name were given instead of a theme object, it
-  would crash.
-* Remove supports-color because it's not actually used.  Uhm.  Yes, I just
-  updated it.  >.>
-
-### v2.7.2
-
-* Use supports-color instead of has-color (as the module has been renamed)
-
-### v2.7.1
-
-* Bug fix: Calls to show/pulse while the progress bar is disabled should still
-  update our internal representation of what would be shown should it be enabled.
-
-### v2.7.0
-
-* New feature: Add new `isEnabled` method to allow introspection of the gauge's
-  "enabledness" as controlled by `.enable()` and `.disable()`.
-
-### v2.6.0
-
-* Bug fix: Don't run the code associated with `enable`/`disable` if the gauge
-  is already enabled or disabled respectively.  This prevents leaking event
-  listeners, amongst other weirdness.
-* New feature: Template items can have default values that will be used if no
-  value was otherwise passed in.
-
-### v2.5.3
-
-* Default to `enabled` only if we have a tty.  Users can always override
-  this by passing in the `enabled` option explicitly or by calling calling
-  `gauge.enable()`.
-
-### v2.5.2
-
-* Externalized `./console-strings.js` into `console-control-strings`.
-
-### v2.5.1
-
-* Update to `signal-exit@3.0.0`, which fixes a compatibility bug with the
-  node profiler.
-* [#39](https://github.com/iarna/gauge/pull/39) Fix tests on 0.10 and add
-  a missing devDependency. ([@helloyou2012](https://github.com/helloyou2012))
-
-### v2.5.0
-
-* Add way to programmatically fetch a list of theme names in a themeset
-  (`Themeset.getThemeNames`).
-
-### v2.4.0
-
-* Add support for setting themesets on existing gauge objects.
-* Add post-IO callback to `gauge.hide()` as it is somtetimes necessary when
-  your terminal is interleaving output from multiple filehandles (ie, stdout
-  & stderr).
-
-### v2.3.1
-
-* Fix a refactor bug in setTheme where it wasn't accepting the various types
-  of args it should.
-
-### v2.3.0
-
-#### FEATURES
-
-* Add setTemplate & setTheme back in.
-* Add support for named themes, you can now ask for things like 'colorASCII'
-  and 'brailleSpinner'.  Of course, you can still pass in theme objects.
-  Additionally you can now pass in an object with `hasUnicode`, `hasColor` and
-  `platform` keys in order to override our guesses as to those values when
-  selecting a default theme from the themeset.
-* Make the output stream optional (it defaults to `process.stderr` now).
-* Add `setWriteTo(stream[, tty])` to change the output stream and,
-  optionally, tty.
-
-#### BUG FIXES & REFACTORING
-
-* Abort the display phase early if we're supposed to be hidden and we are.
-* Stop printing a bunch of spaces at the end of lines, since we're already
-  using an erase-to-end-of-line code anyway.
-* The unicode themes were missing the subsection separator.
-
-### v2.2.1
-
-* Fix image in readme
-
-### v2.2.0
-
-* All new themes API– reference themes by name and pass in custom themes and
-  themesets (themesets get platform support autodetection done on them to
-  select the best theme).  Theme mixins let you add features to all existing
-  themes.
-* Much, much improved test coverage.
-
-### v2.1.0
-
-* Got rid of ░ in the default platform, noUnicode, hasColor theme.  Thanks
-  to @yongtw123 for pointing out this had snuck in.
-* Fiddled with the demo output to make it easier to see the spinner spin. Also
-  added prints before each platforms test output.
-* I forgot to include `signal-exit` in our deps.  <.< Thank you @KenanY for
-  finding this. Then I was lazy and made a new commit instead of using his
-  PR. Again, thank you for your patience @KenenY.
-* Drastically speed up travis testing.
-* Add a small javascript demo (demo.js) for showing off the various themes
-  (and testing them on diff platforms).
-* Change: The subsection separator from ⁄ and / (different chars) to >.
-* Fix crasher: A show or pulse without a label would cause the template renderer
-  to complain about a missing value.
-* New feature: Add the ability to disable the clean-up-on-exit behavior.
-  Not something I expect to be widely desirable, but important if you have
-  multiple distinct gauge instances in your app.
-* Use our own color support detection.
-  The `has-color` module proved too magic for my needs, making assumptions
-  as to which stream we write to and reading command line arguments.
-
-### v2.0.0
-
-This is a major rewrite of the internals.  Externally there are fewer
-changes:
-
-* On node>0.8 gauge object now prints updates at a fixed rate.  This means
-  that when you call `show` it may wate up to `updateInterval` ms before it
-  actually prints an update.  You override this behavior with the
-  `fixedFramerate` option.
-* The gauge object now keeps the cursor hidden as long as it's enabled and
-  shown.
-* The constructor's arguments have changed, now it takes a mandatory output
-  stream and an optional options object.  The stream no longer needs to be
-  an `ansi`ified stream, although it can be if you want (but we won't make
-  use of its special features).
-* Previously the gauge was disabled by default if `process.stdout` wasn't a
-  tty.  Now it always defaults to enabled.  If you want the previous
-  behavior set the `enabled` option to `process.stdout.isTTY`.
-* The constructor's options have changed– see the docs for details.
-* Themes are entirely different.  If you were using a custom theme, or
-  referring to one directly (eg via `Gauge.unicode` or `Gauge.ascii`) then
-  you'll need to change your code.  You can get the equivalent of the latter
-  with:
-  ```
-  var themes = require('gauge/themes')
-  var unicodeTheme = themes(true, true) // returns the color unicode theme for your platform
-  ```
-  The default themes no longer use any ambiguous width characters, so even
-  if you choose to display those as wide your progress bar should still
-  display correctly.
-* Templates are entirely different and if you were using a custom one, you
-  should consult the documentation to learn how to recreate it.  If you were
-  using the default, be aware that it has changed and the result looks quite
-  a bit different.

-### CHANGES FROM 1.x
-
-Gauge 2.x is breaking release, please see the [changelog] for details on
-what's changed if you were previously a user of this module.
-
-[changelog]: CHANGELOG.md
-
-### THE GAUGE CLASS
-
-This is the typical interface to the module– it provides a pretty
-fire-and-forget interface to displaying your status information.
-
-```
-var Gauge = require("gauge")
-
-var gauge = new Gauge([stream], [options])
-```
-
-* **stream** – *(optional, default STDERR)* A stream that progress bar
-  updates are to be written to.  Gauge honors backpressure and will pause
-  most writing if it is indicated.
-* **options** – *(optional)* An option object.
-
-Constructs a new gauge. Gauges are drawn on a single line, and are not drawn
-if **stream** isn't a tty and a tty isn't explicitly provided.
-
-If **stream** is a terminal or if you pass in **tty** to **options** then we
-will detect terminal resizes and redraw to fit.  We do this by watching for
-`resize` events on the tty.  (To work around a bug in verisons of Node prior
-to 2.5.0, we watch for them on stdout if the tty is stderr.) Resizes to
-larger window sizes will be clean, but shrinking the window will always
-result in some cruft.
-
-**IMPORTANT:** If you prevously were passing in a non-tty stream but you still
-want output (for example, a stream wrapped by the `ansi` module) then you
-need to pass in the **tty** option below, as `gauge` needs access to
-the underlying tty in order to do things like terminal resizes and terminal
-width detection.
-
-The **options** object can have the following properties, all of which are
-optional:
-
-* **updateInterval**: How often gauge updates should be drawn, in miliseconds.
-* **fixedFramerate**: Defaults to false on node 0.8, true on everything
-  else.  When this is true a timer is created to trigger once every
-  `updateInterval` ms, when false, updates are printed as soon as they come
-  in but updates more often than `updateInterval` are ignored.  The reason
-  0.8 doesn't have this set to true is that it can't `unref` its timer and
-  so it would stop your program from exiting– if you want to use this
-  feature with 0.8 just make sure you call `gauge.disable()` before you
-  expect your program to exit.
-* **themes**: A themeset to use when selecting the theme to use. Defaults
-  to `gauge/themes`, see the [themes] documentation for details.
-* **theme**: Select a theme for use, it can be a:
-  * Theme object, in which case the **themes** is not used.
-  * The name of a theme, which will be looked up in the current *themes*
-    object.
-  * A configuration object with any of `hasUnicode`, `hasColor` or
-    `platform` keys, which if wlll be used to override our guesses when making
-    a default theme selection.
-
-  If no theme is selected then a default is picked using a combination of our
-  best guesses at your OS, color support and unicode support.
-* **template**: Describes what you want your gauge to look like.  The
-  default is what npm uses.  Detailed [documentation] is later in this
-  document.
-* **hideCursor**: Defaults to true.  If true, then the cursor will be hidden
-  while the gauge is displayed.
-* **tty**: The tty that you're ultimately writing to.  Defaults to the same
-  as **stream**.  This is used for detecting the width of the terminal and
-  resizes. The width used is `tty.columns - 1`. If no tty is available then
-  a width of `79` is assumed.
-* **enabled**: Defaults to true if `tty` is a TTY, false otherwise.  If true
-  the gauge starts enabled.  If disabled then all update commands are
-  ignored and no gauge will be printed until you call `.enable()`.
-* **Plumbing**: The class to use to actually generate the gauge for
-  printing.  This defaults to `require('gauge/plumbing')` and ordinarly you
-  shouldn't need to override this.
-* **cleanupOnExit**: Defaults to true. Ordinarily we register an exit
-  handler to make sure your cursor is turned back on and the progress bar
-  erased when your process exits, even if you Ctrl-C out or otherwise exit
-  unexpectedly. You can disable this and it won't register the exit handler.

-[themes]: #themes
-[documentation]: #templates
-
-#### `gauge.show(section | status, [completed])`
-
-The first argument is either the section, the name of the current thing
-contributing to progress, or an object with keys like **section**,
-**subsection** & **completed** (or any others you have types for in a custom
-template).  If you don't want to update or set any of these you can pass
-`null` and it will be ignored.
-
-The second argument is the percent completed as a value between 0 and 1.
-Without it, completion is just not updated. You'll also note that completion
-can be passed in as part of a status object as the first argument. If both
-it and the completed argument are passed in, the completed argument wins.
-
-#### `gauge.hide([cb])`
-
-Removes the gauge from the terminal.  Optionally, callback `cb` after IO has
-had an opportunity to happen (currently this just means after `setImmediate`
-has called back.)
-
-It turns out this is important when you're pausing the progress bar on one
-filehandle and printing to another– otherwise (with a big enough print) node
-can end up printing the "end progress bar" bits to the progress bar filehandle
-while other stuff is printing to another filehandle. These getting interleaved
-can cause corruption in some terminals.
-
-#### `gauge.pulse([subsection])`
-
-* **subsection** – *(optional)* The specific thing that triggered this pulse
-
-Spins the spinner in the gauge to show output.  If **subsection** is
-included then it will be combined with the last name passed to `gauge.show`.
-
-#### `gauge.disable()`
-
-Hides the gauge and ignores further calls to `show` or `pulse`.
-
-#### `gauge.enable()`
-
-Shows the gauge and resumes updating when `show` or `pulse` is called.
-
-#### `gauge.isEnabled()`
-
-Returns true if the gauge is enabled.
-
-#### `gauge.setThemeset(themes)`
-
-Change the themeset to select a theme from. The same as the `themes` option
-used in the constructor. The theme will be reselected from this themeset.
-
-#### `gauge.setTheme(theme)`
-
-Change the active theme, will be displayed with the next show or pulse. This can be:
-
-* Theme object, in which case the **themes** is not used.
-* The name of a theme, which will be looked up in the current *themes*
-  object.
-* A configuration object with any of `hasUnicode`, `hasColor` or
-  `platform` keys, which if wlll be used to override our guesses when making
-  a default theme selection.
-
-If no theme is selected then a default is picked using a combination of our
-best guesses at your OS, color support and unicode support.
-
-#### `gauge.setTemplate(template)`
-
-Change the active template, will be displayed with the next show or pulse
-
-### Tracking Completion
-
-If you have more than one thing going on that you want to track completion
-of, you may find the related [are-we-there-yet] helpful.  It's `change`
-event can be wired up to the `show` method to get a more traditional
-progress bar interface.

-
-### THEMES
-
-```
-var themes = require('gauge/themes')
-
-// fetch the default color unicode theme for this platform
-var ourTheme = themes({hasUnicode: true, hasColor: true})
-
-// fetch the default non-color unicode theme for osx
-var ourTheme = themes({hasUnicode: true, hasColor: false, platform: 'darwin'})
-
-// create a new theme based on the color ascii theme for this platform
-// that brackets the progress bar with arrows
-var ourTheme = themes.newTheme(theme(hasUnicode: false, hasColor: true}), {
-  preProgressbar: '→',
-  postProgressbar: '←'
-})
-```
-
-The object returned by `gauge/themes` is an instance of the `ThemeSet` class.
-
-```
-var ThemeSet = require('gauge/theme-set')
-var themes = new ThemeSet()
-// or
-var themes = require('gauge/themes')
-var mythemes = themes.newThemeset() // creates a new themeset based on the default themes
-```
-
-#### themes(opts)
-#### themes.getDefault(opts)
-
-Theme objects are a function that fetches the default theme based on
-platform, unicode and color support.
-
-Options is an object with the following properties:
-
-* **hasUnicode** - If true, fetch a unicode theme, if no unicode theme is
-  available then a non-unicode theme will be used.
-* **hasColor** - If true, fetch a color theme, if no color theme is
-  available a non-color theme will be used.
-* **platform** (optional) - Defaults to `process.platform`.  If no
-  platform match is available then `fallback` is used instead.
-
-If no compatible theme can be found then an error will be thrown with a
-`code` of `EMISSINGTHEME`.
-
-#### themes.addTheme(themeName, themeObj)
-#### themes.addTheme(themeName, [parentTheme], newTheme)
-
-Adds a named theme to the themeset.  You can pass in either a theme object,
-as returned by `themes.newTheme` or the arguments you'd pass to
-`themes.newTheme`.
-
-#### themes.getThemeNames()
-
-Return a list of all of the names of the themes in this themeset. Suitable
-for use in `themes.getTheme(…)`.
-
-#### themes.getTheme(name)
-
-Returns the theme object from this theme set named `name`.
-
-If `name` does not exist in this themeset an error will be thrown with
-a `code` of `EMISSINGTHEME`.
-
-#### themes.setDefault([opts], themeName)
-
-`opts` is an object with the following properties.
-
-* **platform** - Defaults to `'fallback'`.  If your theme is platform
-  specific, specify that here with the platform from `process.platform`, eg,
-  `win32`, `darwin`, etc.
-* **hasUnicode** - Defaults to `false`. If your theme uses unicode you
-  should set this to true.
-* **hasColor** - Defaults to `false`.  If your theme uses color you should
-  set this to true.
-
-`themeName` is the name of the theme (as given to `addTheme`) to use for
-this set of `opts`.
-
-#### themes.newTheme([parentTheme,] newTheme)
-
-Create a new theme object based on `parentTheme`.  If no `parentTheme` is
-provided then a minimal parentTheme that defines functions for rendering the
-activity indicator (spinner) and progress bar will be defined. (This
-fallback parent is defined in `gauge/base-theme`.)
-
-newTheme should be a bare object– we'll start by discussing the properties
-defined by the default themes:
-
-* **preProgressbar** - displayed prior to the progress bar, if the progress
-  bar is displayed.
-* **postProgressbar** - displayed after the progress bar, if the progress bar
-  is displayed.
-* **progressBarTheme** - The subtheme passed through to the progress bar
-  renderer, it's an object with `complete` and `remaining` properties
-  that are the strings you want repeated for those sections of the progress
-  bar.
-* **activityIndicatorTheme** - The theme for the activity indicator (spinner),
-  this can either be a string, in which each character is a different step, or
-  an array of strings.
-* **preSubsection** - Displayed as a separator between the `section` and
-  `subsection` when the latter is printed.
-
-More generally, themes can have any value that would be a valid value when rendering
-templates. The properties in the theme are used when their name matches a type in
-the template. Their values can be:
-
-* **strings & numbers** - They'll be included as is
-* **function (values, theme, width)** - Should return what you want in your output.
-  *values* is an object with values provided via `gauge.show`,
-  *theme* is the theme specific to this item (see below) or this theme object,
-  and *width* is the number of characters wide your result should be.
-
-There are a couple of special prefixes:
-
-* **pre** - Is shown prior to the property, if its displayed.
-* **post** - Is shown after the property, if its displayed.
-
-And one special suffix:
-
-* **Theme** - Its value is passed to a function-type item as the theme.
-
-#### themes.addToAllThemes(theme)
-
-This *mixes-in* `theme` into all themes currently defined. It also adds it
-to the default parent theme for this themeset, so future themes added to
-this themeset will get the values from `theme` by default.
-
-#### themes.newThemeset()
-
-Copy the current themeset into a new one.  This allows you to easily inherit
-one themeset from another.
-
-### TEMPLATES
-
-A template is an array of objects and strings that, after being evaluated,
-will be turned into the gauge line.  The default template is:
-
-```javascript
-[
-    {type: 'progressbar', length: 20},
-    {type: 'activityIndicator', kerning: 1, length: 1},
-    {type: 'section', kerning: 1, default: ''},
-    {type: 'subsection', kerning: 1, default: ''}
-]
-```
-
-The various template elements can either be **plain strings**, in which case they will
-be be included verbatum in the output, or objects with the following properties:
-
-* *type* can be any of the following plus any keys you pass into `gauge.show` plus
-  any keys you have on a custom theme.
-  * `section` – What big thing you're working on now.
-  * `subsection` – What component of that thing is currently working.
-  * `activityIndicator` – Shows a spinner using the `activityIndicatorTheme`
-    from your active theme.
-  * `progressbar` – A progress bar representing your current `completed`
-    using the `progressbarTheme` from your active theme.
-* *kerning* – Number of spaces that must be between this item and other
-  items, if this item is displayed at all.
-* *maxLength* – The maximum length for this element. If its value is longer it
-  will be truncated.
-* *minLength* – The minimum length for this element. If its value is shorter it
-  will be padded according to the *align* value.
-* *align* – (Default: left) Possible values "left", "right" and "center". Works
-  as you'd expect from word processors.
-* *length* – Provides a single value for both *minLength* and *maxLength*. If both
-  *length* and *minLength or *maxLength* are specifed then the latter take precedence.
-* *value* – A literal value to use for this template item.
-* *default* – A default value to use for this template item if a value
-  wasn't otherwise passed in.
-
-### PLUMBING
-
-This is the super simple, assume nothing, do no magic internals used by gauge to
-implement its ordinary interface.
-
-```
-var Plumbing = require('gauge/plumbing')
-var gauge = new Plumbing(theme, template, width)
-```
-
-* **theme**: The theme to use.
-* **template**: The template to use.
-* **width**: How wide your gauge should be
-
-#### `gauge.setTheme(theme)`
-
-Change the active theme.
-
-#### `gauge.setTemplate(template)`
-
-Change the active template.
-
-#### `gauge.setWidth(width)`
-
-Change the width to render at.
-
-#### `gauge.hide()`
-
-Return the string necessary to hide the progress bar
-
-#### `gauge.hideCursor()`
-
-Return a string to hide the cursor.
-
-#### `gauge.showCursor()`
-
-Return a string to show the cursor.
-
-#### `gauge.show(status)`
-
-Using `status` for values, render the provided template with the theme and return
-a string that is suitable for printing to update the gauge.

-# object-assign [![Build Status](https://travis-ci.org/sindresorhus/object-assign.svg?branch=master)](https://travis-ci.org/sindresorhus/object-assign)
-
-> ES2015 [`Object.assign()`](http://www.2ality.com/2014/01/object-assign.html) [ponyfill](https://ponyfill.com)
-
-
-## Use the built-in
-
-Node.js 4 and up, as well as every evergreen browser (Chrome, Edge, Firefox, Opera, Safari),
-support `Object.assign()` :tada:. If you target only those environments, then by all
-means, use `Object.assign()` instead of this package.
-
-
-## Install
-
-```
-$ npm install --save object-assign
-```
-
-
-## Usage
-
-```js
-const objectAssign = require('object-assign');
-
-objectAssign({foo: 0}, {bar: 1});
-//=> {foo: 0, bar: 1}
-
-// multiple sources
-objectAssign({foo: 0}, {bar: 1}, {baz: 2});
-//=> {foo: 0, bar: 1, baz: 2}
-
-// overwrites equal keys
-objectAssign({foo: 0}, {foo: 1}, {foo: 2});
-//=> {foo: 2}
-
-// ignores null and undefined sources
-objectAssign({foo: 0}, null, {bar: 1}, undefined);
-//=> {foo: 0, bar: 1}
-```
-
-
-## API
-
-### objectAssign(target, [source, ...])
-
-Assigns enumerable own properties of `source` objects to the `target` object and returns the `target` object. Additional `source` objects will overwrite previous ones.

-## getpass
-
-Get a password from the terminal. Sounds simple? Sounds like the `readline`
-module should be able to do it? NOPE.
-
-## Install and use it
-
-```bash
-npm install --save getpass
-```
-
-```javascript
-const mod_getpass = require('getpass');
-```
-
-## API
-
-### `mod_getpass.getPass([options, ]callback)`
-
-Gets a password from the terminal. If available, this uses `/dev/tty` to avoid
-interfering with any data being piped in or out of stdio.
-
-This function prints a prompt (by default `Password:`) and then accepts input
-without echoing.
-
-Parameters:
-
- * `options`, an Object, with properties:
-   * `prompt`, an optional String
- * `callback`, a `Func(error, password)`, with arguments:
-   * `error`, either `null` (no error) or an `Error` instance
-   * `password`, a String

-# Contributing to Gulp Sass
-
-Gulp Sass is a very light-weight [Gulp](https://github.com/gulpjs/gulp) wrapper for [`node-sass`](https://github.com/sass/node-sass), which in turn is a Node binding for [`libsass`](https://github.com/sass/libsass), which in turn is a port of [`Sass`](https://github.com/sass/sass).

-* Before creating a new issue, perform a [cursory search](https://github.com/issues?utf8=%E2%9C%93&q=repo%3Adlmanning%2Fgulp-sass+repo%3Asass%2Fnode-sass+repo%3Asass%2Flibsass+repo%3Asass%2Fsass+repo%3Asass-eyeglass%2Feyeglass) in the Gulp Sass, Node Sass, Libsass, and main Sass repos to see if a similar issue has already been submitted. Please also refer to our [Common Issues and Their Fixes](https://github.com/dlmanning/gulp-sass/wiki/Common-Issues-and-Their-Fixes) page for some basic troubleshooting.
-* You can create an issue [here](https://github.com/dlmanning/gulp-sass/issues). Please include as many details as possible in your report.
-* Issue titles should be descriptive, explaining at the high level what it is about.
-* Please include the version of `gulp-sass`, Node, and NPM you are using, as well as what operating system you are having a problem on.
-* _Do not open a [pull request](#pull-requests) to resolve an issue without first receiving feedback from a `collaborator` or `owner` and having them agree on a solution forward_.
-* Include screenshots and animated GIFs whenever possible; they are immensely helpful.
-* Issues that have a number of sub-items that need to be complete should use [task lists](https://github.com/blog/1375%0A-task-lists-in-gfm-issues-pulls-comments) to track the sub-items in the main issue comment.
-
-
-## Pull Requests
-
-* **DO NOT ISSUE A PULL REQUEST WITHOUT FIRST [SUBMITTING AN ISSUE](#submitting-issues)**
-* Pull requests should reference their related issues. If the pull request closes an issue, [please reference its closing in your commit messages](https://help.github.com/articles/closing-issues-via-commit-messages/). Pull requests not referencing any issues will be closed.
-* Pull request titles should be descriptive, explaining at the high level what it is doing, and should be written in the same style as [Git commit messages](#git-commit-messages).
-* Update the `CHANGELOG` with the changes made by your pull request, making sure to use the proper [Emoji](#emoji-cheatsheet).
-* Follow our JavaScript styleguides. Tests will fail if you do not.
-* Ensure that you have [EditorConfig](http://editorconfig.org/) installed in your editor of choice and that it is functioning properly.
-* Do not squash or rebase your commits when submitting a Pull Request. It makes it much harder to follow your work and make incremental changes.
-* Update the [CHANGELOG](#maintaining-thechangelog) with your changes.
-* Branches should be made off of the most current `master` branch from `git@github.com:dlmanning/gulp-sass.git`
-* Pull requests should be made into our [master](https://github.com/dlmanning/gulp-sass/tree/master) branch.
-
-### Git Commit Messages
-
-* Use the present tense (`"Add feature"` not `"Added Feature"`)
-* Use the imperative mood (`"Move cursor to…"` not `"Moves cursor to…"`)
-* Limit the first line to 72 characters or less
-* Consider including relevant Emoji from our [Emoji cheatsheet](#emoji-cheatsheet)
-
-## Creating a New Version
-
-Versioning is done through [SEMVER](http://semver.org/). When creating a new version, create new release branch off of `master` with the version's name, and create a new tag with `v` prefixed with the version's name from that branch. 
-
-For instance, if you are creating version `1.1.0`, you would create a branch `release/1.1.0` from `master` and create a tag `v1.1.0` from branch `release/1.1.0`.
-
-### Maintaining the Changelog
-
-The Changelog should have a list of changes made for each version. They should be organized so additions come first, changes come second, and deletions come third. Version numbers should be 2nd level headers with the `v` in front (like a tag) and the date of the version's most recent update should be underneath in italics.
-
-Changelog messages do not need to cover each individual commit made, but rather should have individual summaries of the changes made. Changelog messages should be written in the same style as [Git commit messages](#git-commit-messages).
-
-## Emoji Cheatsheet
-
-When creating creating commits or updating the CHANGELOG, please **start** the commit message or update with one of the following applicable Emoji. Emoji should not be used at the start of issue or pull request titles.

-# Support
+**Migrating your existing project to version 5? Please read our (short!) [migration guide](#migrating-to-version-5).**
 
-Only [Active LTS and Current releases][1] are supported.
+## Support
 
-[1]: https://github.com/nodejs/Release#release-schedule
+Only [Active LTS and Current releases](https://github.com/nodejs/Release#release-schedule) are supported.
 
-# Install
+## Installation
 
+To use `gulp-sass`, you must install both `gulp-sass` itself *and* a Sass compiler. `gulp-sass` supports both [Dart Sass][] and [Node Sass][], although Node Sass is [deprecated](https://sass-lang.com/blog/libsass-is-deprecated). We recommend that you use Dart Sass for new projects, and migrate Node Sass projects to Dart Sass when possible.
+
+Whichever compiler you choose, it's best to install these as dev dependencies:
+
+```sh
+npm install sass gulp-sass --save-dev
+```
+
+### Importing it into your project
+
+`gulp-sass` must be imported into your gulpfile, where you provide it the compiler of your choice. To use `gulp-sass` in a CommonJS module (which is most Node.js environments), do something like this:
+
+```js
+const sass = require('gulp-sass')(require('sass'));
 ```
-npm install node-sass gulp-sass --save-dev
+
+To use `gulp-sass` in an ECMAScript module (which is supported in newer Node.js 14 and later), do something like this:
+
+```js
+import dartSass from 'sass';
+import gulpSass from 'gulp-sass';
+const sass = gulpSass(dartSass);
 ```
 
-# Basic Usage
+## Usage
 
-Something like this will compile your Sass files:
+**Note:** These examples are written for CommonJS modules and assume you're using Gulp 4. For examples that work with Gulp 3, [check the docs for an earlier version of `gulp-sass`](https://github.com/dlmanning/gulp-sass/tree/v4.1.1).
 
-```javascript
-'use strict';
+`gulp-sass` must be used in a Gulp task. Your task can call `sass()` (to asynchronously render your CSS), or `sass.sync()` (to synchronously render your CSS). Then, export your task with the `export` keyword. We'll show some examples of how to do that.
 
-var gulp = require('gulp');
-var sass = require('gulp-sass');
+**⚠️ Note:** When using Dart Sass, **synchronous rendering is twice as fast as asynchronous rendering**. The Sass team is exploring ways to improve asynchronous rendering with Dart Sass, but for now, you will get the best performance from `sass.sync()`. If performance is critical, you can use `node-sass` instead, but bear in mind that `node-sass` may not support modern Sass features you rely on.
 
-sass.compiler = require('node-sass');
+### Render your CSS
+
+To render your CSS with a build task, then watch your files for changes, you might write something like this:
+
+```js
+'use strict';
 
-gulp.task('sass', function () {
+const gulp = require('gulp');
+const sass = require('gulp-sass')(require('sass'));
+
+function buildStyles() {
   return gulp.src('./sass/**/*.scss')
     .pipe(sass().on('error', sass.logError))
     .pipe(gulp.dest('./css'));
-});
+};
 
-gulp.task('sass:watch', function () {
+exports.buildStyles = buildStyles;
+exports.watch = function () {
   gulp.watch('./sass/**/*.scss', ['sass']);
-});
+};
 ```
 
-You can also compile synchronously, doing something like this:
+With synchronous rendering, that Gulp task looks like this:
 
-```javascript
-'use strict';
+```js
+function buildStyles() {
+  return gulp.src('./sass/**/*.scss')
+    .pipe(sass.sync().on('error', sass.logError))
+    .pipe(gulp.dest('./css'));
+};
+```
 
-var gulp = require('gulp');
-var sass = require('gulp-sass');
+### Render with options
 
-sass.compiler = require('node-sass');
+To change the final output of your CSS, you can pass an options object to your renderer. `gulp-sass` supports [Node Sass's render options](https://github.com/sass/node-sass#options), with two unsupported exceptions:
 
-gulp.task('sass', function () {
+- The `data` option, which is used by `gulp-sass` internally.
+- The `file` option, which has undefined behavior that may change without notice.
+
+For example, to compress your CSS, you can call `sass({outputStyle: 'compressed'}`. In the context of a Gulp task, that looks like this:
+
+```js
+function buildStyles() {
   return gulp.src('./sass/**/*.scss')
-    .pipe(sass.sync().on('error', sass.logError))
+    .pipe(sass({outputStyle: 'compressed'}).on('error', sass.logError))
     .pipe(gulp.dest('./css'));
-});
+};
 
-gulp.task('sass:watch', function () {
-  gulp.watch('./sass/**/*.scss', ['sass']);
-});
+exports.buildStyles = buildStyles;
 ```
 
-You can choose whether to use [Dart Sass][] or [Node Sass][] by setting the `sass.compiler` property. Node Sass will be used by default, but it's strongly recommended that you set it explicitly for forwards-compatibility in case the default ever changes.
+Or this for synchronous rendering:
 
-[Dart Sass]: http://sass-lang.com/dart-sass
-[Node Sass]: https://github.com/sass/node-sass
+```js
+function buildStyles() {
+  return gulp.src('./sass/**/*.scss')
+    .pipe(sass.sync({outputStyle: 'compressed'}).on('error', sass.logError))
+    .pipe(gulp.dest('./css'));
+};
 
-Note that when using Dart Sass, **synchronous compilation is twice as fast as asynchronous compilation** by default, due to the overhead of asynchronous callbacks. To avoid this overhead, you can use the [`fibers`](https://www.npmjs.com/package/fibers) package to call asynchronous importers from the synchronous code path. To enable this, pass the `Fiber` class to the `fiber` option:
+exports.buildStyles = buildStyles;
+```
 
-```javascript
-'use strict';
+### Include a source map
 
-var Fiber = require('fibers');
-var gulp = require('gulp');
-var sass = require('gulp-sass');
+`gulp-sass` can be used in tandem with [`gulp-sourcemaps`](https://github.com/gulp-sourcemaps/gulp-sourcemaps) to generate source maps for the Sass-to-CSS compilation. You will need to initialize `gulp-sourcemaps` _before_ running `gulp-sass`, and write the source maps after.
 
-sass.compiler = require('sass');
+```js
+const sourcemaps = require('gulp-sourcemaps');
 
-gulp.task('sass', function () {
+function buildStyles() {
   return gulp.src('./sass/**/*.scss')
-    .pipe(sass({fiber: Fiber}).on('error', sass.logError))
+    .pipe(sourcemaps.init())
+    .pipe(sass().on('error', sass.logError))
+    .pipe(sourcemaps.write())
     .pipe(gulp.dest('./css'));
-});
+}
 
-gulp.task('sass:watch', function () {
-  gulp.watch('./sass/**/*.scss', ['sass']);
-});
+exports.buildStyles = buildStyles;
 ```
 
-## Options
+By default, `gulp-sourcemaps` writes the source maps inline, in the compiled CSS files. To write them to a separate file, specify a path relative to the `gulp.dest()` destination in the `sourcemaps.write()` function.
 
-Pass in options just like you would for [Node Sass](https://github.com/sass/node-sass#options); they will be passed along just as if you were using Node Sass. Except for the `data` option which is used by gulp-sass internally. Using the `file` option is also unsupported and results in undefined behaviour that may change without notice.
+```js
+const sourcemaps = require('gulp-sourcemaps');
 
-For example:
+function buildStyles() {
+  return gulp.src('./sass/**/*.scss')
+    .pipe(sourcemaps.init())
+    .pipe(sass().on('error', sass.logError))
+    .pipe(sourcemaps.write('./maps'))
+    .pipe(gulp.dest('./css'));
+};
 
-```javascript
-gulp.task('sass', function () {
- return gulp.src('./sass/**/*.scss')
-   .pipe(sass({outputStyle: 'compressed'}).on('error', sass.logError))
-   .pipe(gulp.dest('./css'));
-});
+exports.buildStyles = buildStyles;
 ```
 
-Or this for synchronous code:
+<h2 id="migrating-to-version-5">Migrating to version 5</h2>
 
-```javascript
-gulp.task('sass', function () {
- return gulp.src('./sass/**/*.scss')
-   .pipe(sass.sync({outputStyle: 'compressed'}).on('error', sass.logError))
-   .pipe(gulp.dest('./css'));
-});
-```
+`gulp-sass` version 5 requires Node.js 12 or later, and introduces some breaking changes. Additionally, changes in Node.js itself mean that Node fibers can no longer be used to speed up Dart Sass in Node.js 16.
+
+### Setting a Sass compiler
 
-## Source Maps
+As of version 5, `gulp-sass` _does not include a default Sass compiler_, so you must install one (either `node-sass` or `sass`) along with `gulp-sass`.
 
-`gulp-sass` can be used in tandem with [gulp-sourcemaps](https://github.com/floridoo/gulp-sourcemaps) to generate source maps for the Sass to CSS compilation. You will need to initialize [gulp-sourcemaps](https://github.com/floridoo/gulp-sourcemaps) prior to running `gulp-sass` and write the source maps after.
+```sh
+npm install sass gulp-sass --save-dev
+```
+
+Then, you must explicitly set that compiler in your gulpfille. Instead of setting a `compiler` prop on the `gulp-sass` instance, you pass the compiler into a function call when instantiating `gulp-sass`.
 
-```javascript
-var sourcemaps = require('gulp-sourcemaps');
+These changes look something like this:
 
-gulp.task('sass', function () {
- return gulp.src('./sass/**/*.scss')
-  .pipe(sourcemaps.init())
-  .pipe(sass().on('error', sass.logError))
-  .pipe(sourcemaps.write())
-  .pipe(gulp.dest('./css'));
-});
+```diff
+- const sass = require('gulp-sass'));
+- const compiler = require('sass');
+- sass.compiler = compiler;
++ const sass = require('gulp-sass')(require('sass'));
 ```
 
-By default, [gulp-sourcemaps](https://github.com/floridoo/gulp-sourcemaps) writes the source maps inline in the compiled CSS files. To write them to a separate file, specify a path relative to the `gulp.dest()` destination in the `sourcemaps.write()` function.
-
-```javascript
-var sourcemaps = require('gulp-sourcemaps');
-gulp.task('sass', function () {
- return gulp.src('./sass/**/*.scss')
-  .pipe(sourcemaps.init())
-  .pipe(sass().on('error', sass.logError))
-  .pipe(sourcemaps.write('./maps'))
-  .pipe(gulp.dest('./css'));
-});
+If you're migrating an ECMAScript module, that'll look something like this:
+
+```diff
+import dartSass from 'sass';
+- import sass from 'gulp-sass';
+- sass.compiler = dartSass;
+
+import dartSass from 'sass';
++ import gulpSass from 'gulp-sass';
++ const sass = gulpSass(dartSass);
 ```
 
-# Issues
+### What about fibers?
 
-`gulp-sass` is a very light-weight wrapper around either [Dart Sass][] or [Node Sass][] (which in turn is a Node binding for [LibSass][]). Because of this, the issue you're having likely isn't a `gulp-sass` issue, but an issue with one those projects or with [Sass][] as a whole.
+We used to recommend Node fibers as a way to speed up asynchronous rendering with Dart Sass. Unfortunately, [Node fibers are discontinued](https://sass-lang.com/blog/node-fibers-discontinued) and will not work in Node.js 16. The Sass team is exploring its options for future performance improvements, but for now, you will get the best performance from `sass.sync()`.

-# ansi-styles [![Build Status](https://travis-ci.org/chalk/ansi-styles.svg?branch=master)](https://travis-ci.org/chalk/ansi-styles)
-
-> [ANSI escape codes](http://en.wikipedia.org/wiki/ANSI_escape_code#Colors_and_Styles) for styling strings in the terminal
-
-You probably want the higher-level [chalk](https://github.com/chalk/chalk) module for styling your strings.
-
-<img src="https://cdn.rawgit.com/chalk/ansi-styles/8261697c95bf34b6c7767e2cbe9941a851d59385/screenshot.svg" width="900">
-
-
-## Install
-
-```
-$ npm install ansi-styles
-```
-
-
-## Usage
-
-```js
-const style = require('ansi-styles');
-
-console.log(`${style.green.open}Hello world!${style.green.close}`);
-
-
-// Color conversion between 16/256/truecolor
-// NOTE: If conversion goes to 16 colors or 256 colors, the original color
-//       may be degraded to fit that color palette. This means terminals
-//       that do not support 16 million colors will best-match the
-//       original color.
-console.log(style.bgColor.ansi.hsl(120, 80, 72) + 'Hello world!' + style.bgColor.close);
-console.log(style.color.ansi256.rgb(199, 20, 250) + 'Hello world!' + style.color.close);
-console.log(style.color.ansi16m.hex('#ABCDEF') + 'Hello world!' + style.color.close);
-```
-
-## API
-
-Each style has an `open` and `close` property.
-
-
-## Styles
-
-### Modifiers
-
-- `reset`
-- `bold`
-- `dim`
-- `italic` *(Not widely supported)*
-- `underline`
-- `inverse`
-- `hidden`
-- `strikethrough` *(Not widely supported)*
-
-### Colors
-
-- `black`
-- `red`
-- `green`
-- `yellow`
-- `blue`
-- `magenta`
-- `cyan`
-- `white`
-- `gray` ("bright black")
-- `redBright`
-- `greenBright`
-- `yellowBright`
-- `blueBright`
-- `magentaBright`
-- `cyanBright`
-- `whiteBright`
-
-### Background colors
-
-- `bgBlack`
-- `bgRed`
-- `bgGreen`
-- `bgYellow`
-- `bgBlue`
-- `bgMagenta`
-- `bgCyan`
-- `bgWhite`
-- `bgBlackBright`
-- `bgRedBright`
-- `bgGreenBright`
-- `bgYellowBright`
-- `bgBlueBright`
-- `bgMagentaBright`
-- `bgCyanBright`
-- `bgWhiteBright`
-
-
-## Advanced usage
-
-By default, you get a map of styles, but the styles are also available as groups. They are non-enumerable so they don't show up unless you access them explicitly. This makes it easier to expose only a subset in a higher-level module.
-
-- `style.modifier`
-- `style.color`
-- `style.bgColor`
-
-###### Example
-
-```js
-console.log(style.color.green.open);
-```
-
-Raw escape codes (i.e. without the CSI escape prefix `\u001B[` and render mode postfix `m`) are available under `style.codes`, which returns a `Map` with the open codes as keys and close codes as values.
-
-###### Example
-
-```js
-console.log(style.codes.get(36));
-//=> 39
-```
-
-
-## [256 / 16 million (TrueColor) support](https://gist.github.com/XVilka/8346728)
-
-`ansi-styles` uses the [`color-convert`](https://github.com/Qix-/color-convert) package to allow for converting between various colors and ANSI escapes, with support for 256 and 16 million colors.
-
-To use these, call the associated conversion function with the intended output, for example:
-
-```js
-style.color.ansi.rgb(100, 200, 15); // RGB to 16 color ansi foreground code
-style.bgColor.ansi.rgb(100, 200, 15); // RGB to 16 color ansi background code
-
-style.color.ansi256.hsl(120, 100, 60); // HSL to 256 color ansi foreground code
-style.bgColor.ansi256.hsl(120, 100, 60); // HSL to 256 color ansi foreground code
-
-style.color.ansi16m.hex('#C0FFEE'); // Hex (RGB) to 16 million color foreground code
-style.bgColor.ansi16m.hex('#C0FFEE'); // Hex (RGB) to 16 million color background code
-```

-
-## Usage
-
-```js
-const chalk = require('chalk');
-
-console.log(chalk.blue('Hello world!'));
-```
-
-Chalk comes with an easy to use composable API where you just chain and nest the styles you want.
-
-```js
-const chalk = require('chalk');
-const log = console.log;
-
-// Combine styled and normal strings
-log(chalk.blue('Hello') + ' World' + chalk.red('!'));
-
-// Compose multiple styles using the chainable API
-log(chalk.blue.bgRed.bold('Hello world!'));
-
-// Pass in multiple arguments
-log(chalk.blue('Hello', 'World!', 'Foo', 'bar', 'biz', 'baz'));
-
-// Nest styles
-log(chalk.red('Hello', chalk.underline.bgBlue('world') + '!'));
-
-// Nest styles of the same type even (color, underline, background)
-log(chalk.green(
-	'I am a green line ' +
-	chalk.blue.underline.bold('with a blue substring') +
-	' that becomes green again!'
-));
-
-// ES2015 template literal
-log(`
-CPU: ${chalk.red('90%')}
-RAM: ${chalk.green('40%')}
-DISK: ${chalk.yellow('70%')}
-`);
-
-// ES2015 tagged template literal
-log(chalk`
-CPU: {red ${cpu.totalPercent}%}
-RAM: {green ${ram.used / ram.total * 100}%}
-DISK: {rgb(255,131,0) ${disk.used / disk.total * 100}%}
-`);
-
-// Use RGB colors in terminal emulators that support it.
-log(chalk.keyword('orange')('Yay for orange colored text!'));
-log(chalk.rgb(123, 45, 67).underline('Underlined reddish color'));
-log(chalk.hex('#DEADED').bold('Bold gray!'));
-```
-
-Easily define your own themes:
-
-```js
-const chalk = require('chalk');
-
-const error = chalk.bold.red;
-const warning = chalk.keyword('orange');
-
-console.log(error('Error!'));
-console.log(warning('Warning!'));
-```
-
-Take advantage of console.log [string substitution](https://nodejs.org/docs/latest/api/console.html#console_console_log_data_args):
-
-```js
-const name = 'Sindre';
-console.log(chalk.green('Hello %s'), name);
-//=> 'Hello Sindre'
-```
-
-
-## API
-
-### chalk.`<style>[.<style>...](string, [string...])`
-
-Example: `chalk.red.bold.underline('Hello', 'world');`
-
-Chain [styles](#styles) and call the last one as a method with a string argument. Order doesn't matter, and later styles take precedent in case of a conflict. This simply means that `chalk.red.yellow.green` is equivalent to `chalk.green`.
-
-Multiple arguments will be separated by space.
-
-### chalk.enabled
-
-Color support is automatically detected, as is the level (see `chalk.level`). However, if you'd like to simply enable/disable Chalk, you can do so via the `.enabled` property.
-
-Chalk is enabled by default unless explicitly disabled via the constructor or `chalk.level` is `0`.
-
-If you need to change this in a reusable module, create a new instance:
-
-```js
-const ctx = new chalk.constructor({enabled: false});
-```
-
-### chalk.level
-
-Color support is automatically detected, but you can override it by setting the `level` property. You should however only do this in your own code as it applies globally to all Chalk consumers.
-
-If you need to change this in a reusable module, create a new instance:
-
-```js
-const ctx = new chalk.constructor({level: 0});
-```
-
-Levels are as follows:
-
-0. All colors disabled
-1. Basic color support (16 colors)
-2. 256 color support
-3. Truecolor support (16 million colors)
-
-### chalk.supportsColor
-
-Detect whether the terminal [supports color](https://github.com/chalk/supports-color). Used internally and handled for you, but exposed for convenience.
-
-Can be overridden by the user with the flags `--color` and `--no-color`. For situations where using `--color` is not possible, add the environment variable `FORCE_COLOR=1` to forcefully enable color or `FORCE_COLOR=0` to forcefully disable. The use of `FORCE_COLOR` overrides all other color support checks.
-
-Explicit 256/Truecolor mode can be enabled using the `--color=256` and `--color=16m` flags, respectively.

-
-## Tagged template literal
-
-Chalk can be used as a [tagged template literal](http://exploringjs.com/es6/ch_template-literals.html#_tagged-template-literals).
-
-```js
-const chalk = require('chalk');
-
-const miles = 18;
-const calculateFeet = miles => miles * 5280;
-
-console.log(chalk`
-  There are {bold 5280 feet} in a mile.
-  In {bold ${miles} miles}, there are {green.bold ${calculateFeet(miles)} feet}.
-`);
-```
-
-Blocks are delimited by an opening curly brace (`{`), a style, some content, and a closing curly brace (`}`).
-
-Template styles are chained exactly like normal Chalk styles. The following two statements are equivalent:
-
-```js
-console.log(chalk.bold.rgb(10, 100, 200)('Hello!'));
-console.log(chalk`{bold.rgb(10,100,200) Hello!}`);
-```
-
-Note that function styles (`rgb()`, `hsl()`, `keyword()`, etc.) may not contain spaces between parameters.
-
-All interpolated values (`` chalk`${foo}` ``) are converted to strings via the `.toString()` method. All curly braces (`{` and `}`) in interpolated value strings are escaped.
-
-
-## 256 and Truecolor color support
-
-Chalk supports 256 colors and [Truecolor](https://gist.github.com/XVilka/8346728) (16 million colors) on supported terminal apps.
-
-Colors are downsampled from 16 million RGB values to an ANSI color format that is supported by the terminal emulator (or by specifying `{level: n}` as a Chalk option). For example, Chalk configured to run at level 1 (basic color support) will downsample an RGB value of #FF0000 (red) to 31 (ANSI escape for red).
-
-Examples:
-
-- `chalk.hex('#DEADED').underline('Hello, world!')`
-- `chalk.keyword('orange')('Some orange text')`
-- `chalk.rgb(15, 100, 204).inverse('Hello!')`
-
-Background versions of these models are prefixed with `bg` and the first level of the module capitalized (e.g. `keyword` for foreground colors and `bgKeyword` for background colors).
-
-- `chalk.bgHex('#DEADED').underline('Hello, world!')`
-- `chalk.bgKeyword('orange')('Some orange text')`
-- `chalk.bgRgb(15, 100, 204).inverse('Hello!')`
-
-The following color models can be used:
-
-- [`rgb`](https://en.wikipedia.org/wiki/RGB_color_model) - Example: `chalk.rgb(255, 136, 0).bold('Orange!')`
-- [`hex`](https://en.wikipedia.org/wiki/Web_colors#Hex_triplet) - Example: `chalk.hex('#FF8800').bold('Orange!')`
-- [`keyword`](https://www.w3.org/wiki/CSS/Properties/color/keywords) (CSS keywords) - Example: `chalk.keyword('orange').bold('Orange!')`
-- [`hsl`](https://en.wikipedia.org/wiki/HSL_and_HSV) - Example: `chalk.hsl(32, 100, 50).bold('Orange!')`
-- [`hsv`](https://en.wikipedia.org/wiki/HSL_and_HSV) - Example: `chalk.hsv(32, 100, 100).bold('Orange!')`
-- [`hwb`](https://en.wikipedia.org/wiki/HWB_color_model)  - Example: `chalk.hwb(32, 0, 50).bold('Orange!')`
-- `ansi16`
-- `ansi256`
-
-
-## Windows
-
-If you're on Windows, do yourself a favor and use [`cmder`](http://cmder.net/) instead of `cmd.exe`.
-
-
-## Origin story
-
-[colors.js](https://github.com/Marak/colors.js) used to be the most popular string styling module, but it has serious deficiencies like extending `String.prototype` which causes all kinds of [problems](https://github.com/yeoman/yo/issues/68) and the package is unmaintained. Although there are other packages, they either do too much or not enough. Chalk is a clean and focused alternative.

-# supports-color [![Build Status](https://travis-ci.org/chalk/supports-color.svg?branch=master)](https://travis-ci.org/chalk/supports-color)
-
-> Detect whether a terminal supports color
-
-
-## Install
-
-```
-$ npm install supports-color
-```
-
-
-## Usage
-
-```js
-const supportsColor = require('supports-color');
-
-if (supportsColor.stdout) {
-	console.log('Terminal stdout supports color');
-}
-
-if (supportsColor.stdout.has256) {
-	console.log('Terminal stdout supports 256 colors');
-}
-
-if (supportsColor.stderr.has16m) {
-	console.log('Terminal stderr supports 16 million colors (truecolor)');
-}
-```
-
-
-## API
-
-Returns an `Object` with a `stdout` and `stderr` property for testing either streams. Each property is an `Object`, or `false` if color is not supported.
-
-The `stdout`/`stderr` objects specifies a level of support for color through a `.level` property and a corresponding flag:
-
-- `.level = 1` and `.hasBasic = true`: Basic color support (16 colors)
-- `.level = 2` and `.has256 = true`: 256 color support
-- `.level = 3` and `.has16m = true`: Truecolor support (16 million colors)
-
-
-## Info
-
-It obeys the `--color` and `--no-color` CLI flags.
-
-Can be overridden by the user with the flags `--color` and `--no-color`. For situations where using `--color` is not possible, add the environment variable `FORCE_COLOR=1` to forcefully enable color or `FORCE_COLOR=0` to forcefully disable. The use of `FORCE_COLOR` overrides all other color support checks.
-
-Explicit 256/Truecolor mode can be enabled using the `--color=256` and `--color=16m` flags, respectively.

-has-unicode
-===========
-
-Try to guess if your terminal supports unicode
-
-```javascript
-var hasUnicode = require("has-unicode")
-
-if (hasUnicode()) {
-  // the terminal probably has unicode support
-}
-```
-```javascript
-var hasUnicode = require("has-unicode").tryHarder
-hasUnicode(function(unicodeSupported) {
-  if (unicodeSupported) {
-    // the terminal probably has unicode support
-  }
-})
-```
-
-## Detecting Unicode
-
-What we actually detect is UTF-8 support, as that's what Node itself supports.
-If you have a UTF-16 locale then you won't be detected as unicode capable.
-
-### Windows
-
-Since at least Windows 7, `cmd` and `powershell` have been unicode capable,
-but unfortunately even then it's not guaranteed. In many localizations it
-still uses legacy code pages and there's no facility short of running
-programs or linking C++ that will let us detect this. As such, we
-report any Windows installation as NOT unicode capable, and recommend
-that you encourage your users to override this via config.
-
-### Unix Like Operating Systems
-
-We look at the environment variables `LC_ALL`, `LC_CTYPE`, and `LANG` in
-that order.  For `LC_ALL` and `LANG`, it looks for `.UTF-8` in the value. 
-For `LC_CTYPE` it looks to see if the value is `UTF-8`.  This is sufficient
-for most POSIX systems.  While locale data can be put in `/etc/locale.conf`
-as well, AFAIK it's always copied into the environment.

-# node-http-signature
-
-node-http-signature is a node.js library that has client and server components
-for Joyent's [HTTP Signature Scheme](http_signing.md).
-
-## Usage
-
-Note the example below signs a request with the same key/cert used to start an
-HTTP server. This is almost certainly not what you actually want, but is just
-used to illustrate the API calls; you will need to provide your own key
-management in addition to this library.
-
-### Client
-
-```js
-var fs = require('fs');
-var https = require('https');
-var httpSignature = require('http-signature');
-
-var key = fs.readFileSync('./key.pem', 'ascii');
-
-var options = {
-  host: 'localhost',
-  port: 8443,
-  path: '/',
-  method: 'GET',
-  headers: {}
-};
-
-// Adds a 'Date' header in, signs it, and adds the
-// 'Authorization' header in.
-var req = https.request(options, function(res) {
-  console.log(res.statusCode);
-});
-
-
-httpSignature.sign(req, {
-  key: key,
-  keyId: './cert.pem'
-});
-
-req.end();
-```
-
-### Server
-
-```js
-var fs = require('fs');
-var https = require('https');
-var httpSignature = require('http-signature');
-
-var options = {
-  key: fs.readFileSync('./key.pem'),
-  cert: fs.readFileSync('./cert.pem')
-};
-
-https.createServer(options, function (req, res) {
-  var rc = 200;
-  var parsed = httpSignature.parseRequest(req);
-  var pub = fs.readFileSync(parsed.keyId, 'ascii');
-  if (!httpSignature.verifySignature(parsed, pub))
-    rc = 401;
-
-  res.writeHead(rc);
-  res.end();
-}).listen(8443);
-```
-
-## Installation
-
-    npm install http-signature
-
-## License
-
-MIT.

-# Abstract
-
-This document describes a way to add origin authentication, message integrity,
-and replay resistance to HTTP REST requests.  It is intended to be used over
-the HTTPS protocol.
-
-# Copyright Notice

-Copyright (c) 2011 Joyent, Inc. and the persons identified as document authors.

-
-# Introduction
-
-This protocol is intended to provide a standard way for clients to sign HTTP
-requests.  RFC2617 (HTTP Authentication) defines Basic and Digest authentication
-mechanisms, and RFC5246 (TLS 1.2) defines client-auth, both of which are widely
-employed on the Internet today.  However, it is common place that the burdens of
-PKI prevent web service operators from deploying that methodology, and so many
-fall back to Basic authentication, which has poor security characteristics.
-
-Additionally, OAuth provides a fully-specified alternative for authorization
-of web service requests, but is not (always) ideal for machine to machine
-communication, as the key acquisition steps (generally) imply a fixed
-infrastructure that may not make sense to a service provider (e.g., symmetric
-keys).
-
-Several web service providers have invented their own schemes for signing
-HTTP requests, but to date, none have been placed in the public domain as a
-standard.  This document serves that purpose.  There are no techniques in this
-proposal that are novel beyond previous art, however, this aims to be a simple
-mechanism for signing these requests.
-
-# Signature Authentication Scheme
-
-The "signature" authentication scheme is based on the model that the client must
-authenticate itself with a digital signature produced by either a private
-asymmetric key (e.g., RSA) or a shared symmetric key (e.g., HMAC).  The scheme
-is parameterized enough such that it is not bound to any particular key type or
-signing algorithm.  However, it does explicitly assume that clients can send an
-HTTP `Date` header.
-
-## Authorization Header
-
-The client is expected to send an Authorization header (as defined in RFC 2617)
-with the following parameterization:
-
-    credentials := "Signature" params
-    params := 1#(keyId | algorithm | [headers] | [ext] | signature)
-    digitalSignature := plain-string
-
-    keyId := "keyId" "=" <"> plain-string <">
-    algorithm := "algorithm" "=" <"> plain-string <">
-    headers := "headers" "=" <"> 1#headers-value <">
-    ext := "ext" "=" <"> plain-string <">
-    signature := "signature" "=" <"> plain-string <">
-
-    headers-value := plain-string
-    plain-string   = 1*( %x20-21 / %x23-5B / %x5D-7E )
-
-### Signature Parameters
-
-#### keyId
-
-REQUIRED.  The `keyId` field is an opaque string that the server can use to look
-up the component they need to validate the signature.  It could be an SSH key
-fingerprint, an LDAP DN, etc.  Management of keys and assignment of `keyId` is
-out of scope for this document.
-
-#### algorithm
-
-REQUIRED. The `algorithm` parameter is used if the client and server agree on a
-non-standard digital signature algorithm.  The full list of supported signature
-mechanisms is listed below.
-
-#### headers
-
-OPTIONAL.  The `headers` parameter is used to specify the list of HTTP headers
-used to sign the request.  If specified, it should be a quoted list of HTTP
-header names, separated by a single space character.  By default, only one
-HTTP header is signed, which is the `Date` header.  Note that the list MUST be
-specified in the order the values are concatenated together during signing. To
-include the HTTP request line in the signature calculation, use the special
-`request-line` value.  While this is overloading the definition of `headers` in
-HTTP linguism, the request-line is defined in RFC 2616, and as the outlier from
-headers in useful signature calculation, it is deemed simpler to simply use
-`request-line` than to add a separate parameter for it.
-
-#### extensions
-
-OPTIONAL.  The `extensions` parameter is used to include additional information
-which is covered by the request.  The content and format of the string is out of
-scope for this document, and expected to be specified by implementors.
-
-#### signature
-
-REQUIRED.  The `signature` parameter is a `Base64` encoded digital signature
-generated by the client. The client uses the `algorithm` and `headers` request
-parameters to form a canonicalized `signing string`.  This `signing string` is
-then signed with the key associated with `keyId` and the algorithm
-corresponding to `algorithm`.  The `signature` parameter is then set to the
-`Base64` encoding of the signature.
-
-### Signing String Composition
-
-In order to generate the string that is signed with a key, the client MUST take
-the values of each HTTP header specified by `headers` in the order they appear.
-
-1. If the header name is not `request-line` then append the lowercased header
-   name followed with an ASCII colon `:` and an ASCII space ` `.
-2. If the header name is `request-line` then append the HTTP request line,
-   otherwise append the header value.
-3. If value is not the last value then append an ASCII newline `\n`. The string
-   MUST NOT include a trailing ASCII newline.
-
-# Example Requests
-
-All requests refer to the following request (body omitted):
-
-    POST /foo HTTP/1.1
-    Host: example.org
-    Date: Tue, 07 Jun 2014 20:51:35 GMT
-    Content-Type: application/json
-    Digest: SHA-256=X48E9qOokqqrvdts8nOJRJN3OWDUoyWxBf7kbu9DBPE=
-    Content-Length: 18
-
-The "rsa-key-1" keyId refers to a private key known to the client and a public
-key known to the server. The "hmac-key-1" keyId refers to key known to the
-client and server.
-
-## Default parameterization
-
-The authorization header and signature would be generated as:
-
-    Authorization: Signature keyId="rsa-key-1",algorithm="rsa-sha256",signature="Base64(RSA-SHA256(signing string))"
-
-The client would compose the signing string as:
-
-    date: Tue, 07 Jun 2014 20:51:35 GMT
-
-## Header List
-
-The authorization header and signature would be generated as:
-
-    Authorization: Signature keyId="rsa-key-1",algorithm="rsa-sha256",headers="(request-target) date content-type digest",signature="Base64(RSA-SHA256(signing string))"
-
-The client would compose the signing string as (`+ "\n"` inserted for
-readability):
-
-    (request-target) post /foo + "\n"
-    date: Tue, 07 Jun 2011 20:51:35 GMT + "\n"
-    content-type: application/json + "\n"
-    digest: SHA-256=Base64(SHA256(Body))
-
-## Algorithm
-
-The authorization header and signature would be generated as:
-
-    Authorization: Signature keyId="hmac-key-1",algorithm="hmac-sha1",signature="Base64(HMAC-SHA1(signing string))"
-
-The client would compose the signing string as:
-
-    date: Tue, 07 Jun 2011 20:51:35 GMT
-
-# Signing Algorithms
-
-Currently supported algorithm names are:
-
-* rsa-sha1
-* rsa-sha256
-* rsa-sha512
-* dsa-sha1
-* hmac-sha1
-* hmac-sha256
-* hmac-sha512
-
-# Security Considerations
-
-## Default Parameters
-
-Note the default parameterization of the `Signature` scheme is only safe if all
-requests are carried over a secure transport (i.e., TLS).  Sending the default
-scheme over a non-secure transport will leave the request vulnerable to
-spoofing, tampering, replay/repudiation, and integrity violations (if using the
-STRIDE threat-modeling methodology).
-
-## Insecure Transports
-
-If sending the request over plain HTTP, service providers SHOULD require clients
-to sign ALL HTTP headers, and the `request-line`.  Additionally, service
-providers SHOULD require `Content-MD5` calculations to be performed to ensure
-against any tampering from clients.
-
-## Nonces
-
-Nonces are out of scope for this document simply because many service providers
-fail to implement them correctly, or do not adopt security specifications
-because of the infrastructure complexity.  Given the `header` parameterization,
-a service provider is fully enabled to add nonce semantics into this scheme by
-using something like an `x-request-nonce` header, and ensuring it is signed
-with the `Date` header.
-
-## Clock Skew
-
-As the default scheme is to sign the `Date` header, service providers SHOULD
-protect against logged replay attacks by enforcing a clock skew.  The server
-SHOULD be synchronized with NTP, and the recommendation in this specification
-is to allow 300s of clock skew (in either direction).
-
-## Required Headers to Sign
-
-It is out of scope for this document to dictate what headers a service provider
-will want to enforce, but service providers SHOULD at minimum include the
-`Date` header.

-## Generating and verifying signatures using `openssl`
-
-The `openssl` commandline tool can be used to generate or verify the signatures listed above.
-
-Compose the signing string as usual, and pipe it into the the `openssl dgst` command, then into `openssl enc -base64`, as follows:
-
-    $ printf 'date: Thu, 05 Jan 2014 21:31:40 GMT' | \
-      openssl dgst -binary -sign /path/to/private.pem -sha256 | \
-      openssl enc -base64
-    jKyvPcxB4JbmYY4mByyBY7cZfNl4OW9Hp...
-    $
-
-The `-sha256` option is necessary to produce an `rsa-sha256` signature. You can select other hash algorithms such as `sha1` by changing this argument.
-
-To verify a signature, first save the signature data, Base64-decoded, into a file, then use `openssl dgst` again with the `-verify` option:
-
-    $ echo 'jKyvPcxB4JbmYY4mByy...' | openssl enc -A -d -base64 > signature
-    $ printf 'date: Thu, 05 Jan 2014 21:31:40 GMT' | \
-      openssl dgst -sha256 -verify /path/to/public.pem -signature ./signature
-    Verified OK
-    $
-
-## Generating and verifying signatures using `sshpk-sign`
-
-You can also generate and check signatures using the `sshpk-sign` tool which is
-included with the `sshpk` package in `npm`.
-
-Compose the signing string as above, and pipe it into `sshpk-sign` as follows:
-
-    $ printf 'date: Thu, 05 Jan 2014 21:31:40 GMT' | \
-      sshpk-sign -i /path/to/private.pem
-    jKyvPcxB4JbmYY4mByyBY7cZfNl4OW9Hp...
-    $
-
-This will produce an `rsa-sha256` signature by default, as you can see using
-the `-v` option:
-
-    sshpk-sign: using rsa-sha256 with a 1024 bit key
-
-You can also use `sshpk-verify` in a similar manner:
-
-    $ printf 'date: Thu, 05 Jan 2014 21:31:40 GMT' | \
-      sshpk-verify -i ./public.pem -s 'jKyvPcxB4JbmYY...'
-    OK

+## Introduction
+
+[Immutable][] data cannot be changed once created, leading to much simpler
+application development, no defensive copying, and enabling advanced memoization
+and change detection techniques with simple logic. [Persistent][] data presents
+a mutative API which does not update the data in-place, but instead always
+yields new updated data.
+
+Immutable.js provides many Persistent Immutable data structures including:
+`List`, `Stack`, `Map`, `OrderedMap`, `Set`, `OrderedSet` and `Record`.
+
+These data structures are highly efficient on modern JavaScript VMs by using
+structural sharing via [hash maps tries][] and [vector tries][] as popularized
+by Clojure and Scala, minimizing the need to copy or cache data.
+
+Immutable.js also provides a lazy `Seq`, allowing efficient
+chaining of collection methods like `map` and `filter` without creating
+intermediate representations. Create some `Seq` with `Range` and `Repeat`.

+
+## Getting started
+
+Install `immutable` using npm.
+
+```shell
+npm install immutable
+```
+
+Or install using yarn.
+
+```shell
+yarn add immutable
+```
+
+Then require it into any module.
+
+<!-- runkit:activate -->
+
+```js
+const { Map } = require('immutable');
+const map1 = Map({ a: 1, b: 2, c: 3 });
+const map2 = map1.set('b', 50);
+map1.get('b') + ' vs. ' + map2.get('b'); // 2 vs. 50
+```
+
+### Browser
+
+Immutable.js has no dependencies, which makes it predictable to include in a Browser.
+
+It's highly recommended to use a module bundler like [webpack](https://webpack.github.io/),
+[rollup](https://rollupjs.org/), or
+[browserify](https://browserify.org/). The `immutable` npm module works
+without any additional consideration. All examples throughout the documentation
+will assume use of this kind of tool.
+
+Alternatively, Immutable.js may be directly included as a script tag. Download
+or link to a CDN such as [CDNJS](https://cdnjs.com/libraries/immutable)
+or [jsDelivr](https://www.jsdelivr.com/package/npm/immutable).
+
+Use a script tag to directly add `Immutable` to the global scope:
+
+```html
+<script src="immutable.min.js"></script>
+<script>
+  var map1 = Immutable.Map({ a: 1, b: 2, c: 3 });
+  var map2 = map1.set('b', 50);
+  map1.get('b'); // 2
+  map2.get('b'); // 50
+</script>
+```
+
+Or use an AMD-style loader (such as [RequireJS](https://requirejs.org/)):
+
+```js
+require(['./immutable.min.js'], function (Immutable) {
+  var map1 = Immutable.Map({ a: 1, b: 2, c: 3 });
+  var map2 = map1.set('b', 50);
+  map1.get('b'); // 2
+  map2.get('b'); // 50
+});
+```
+
+### Flow & TypeScript
+
+Use these Immutable collections and sequences as you would use native
+collections in your [Flowtype](https://flowtype.org/) or [TypeScript](https://typescriptlang.org) programs while still taking
+advantage of type generics, error detection, and auto-complete in your IDE.
+
+Installing `immutable` via npm brings with it type definitions for Flow (v0.55.0 or higher)
+and TypeScript (v2.1.0 or higher), so you shouldn't need to do anything at all!
+
+#### Using TypeScript with Immutable.js v4
+
+Immutable.js type definitions embrace ES2015. While Immutable.js itself supports
+legacy browsers and environments, its type definitions require TypeScript's 2015
+lib. Include either `"target": "es2015"` or `"lib": "es2015"` in your
+`tsconfig.json`, or provide `--target es2015` or `--lib es2015` to the
+`tsc` command.
+
+<!-- runkit:activate -->
+
+```js
+const { Map } = require('immutable');
+const map1 = Map({ a: 1, b: 2, c: 3 });
+const map2 = map1.set('b', 50);
+map1.get('b') + ' vs. ' + map2.get('b'); // 2 vs. 50
+```
+
+#### Using TypeScript with Immutable.js v3 and earlier:
+
+Previous versions of Immutable.js include a reference file which you can include
+via relative path to the type definitions at the top of your file.
+
+```js
+///<reference path='./node_modules/immutable/dist/immutable.d.ts'/>
+import Immutable from 'immutable';
+var map1: Immutable.Map<string, number>;
+map1 = Immutable.Map({ a: 1, b: 2, c: 3 });
+var map2 = map1.set('b', 50);
+map1.get('b'); // 2
+map2.get('b'); // 50
+```
+
+## The case for Immutability
+
+Much of what makes application development difficult is tracking mutation and
+maintaining state. Developing with immutable data encourages you to think
+differently about how data flows through your application.
+
+Subscribing to data events throughout your application creates a huge overhead of
+book-keeping which can hurt performance, sometimes dramatically, and creates
+opportunities for areas of your application to get out of sync with each other
+due to easy to make programmer error. Since immutable data never changes,
+subscribing to changes throughout the model is a dead-end and new data can only
+ever be passed from above.
+
+This model of data flow aligns well with the architecture of [React][]
+and especially well with an application designed using the ideas of [Flux][].
+
+When data is passed from above rather than being subscribed to, and you're only
+interested in doing work when something has changed, you can use equality.
+
+Immutable collections should be treated as _values_ rather than _objects_. While
+objects represent some thing which could change over time, a value represents
+the state of that thing at a particular instance of time. This principle is most
+important to understanding the appropriate use of immutable data. In order to
+treat Immutable.js collections as values, it's important to use the
+`Immutable.is()` function or `.equals()` method to determine _value equality_
+instead of the `===` operator which determines object _reference identity_.
+
+<!-- runkit:activate -->
+
+```js
+const { Map } = require('immutable');
+const map1 = Map({ a: 1, b: 2, c: 3 });
+const map2 = Map({ a: 1, b: 2, c: 3 });
+map1.equals(map2); // true
+map1 === map2; // false
+```
+
+Note: As a performance optimization Immutable.js attempts to return the existing
+collection when an operation would result in an identical collection, allowing
+for using `===` reference equality to determine if something definitely has not
+changed. This can be extremely useful when used within a memoization function
+which would prefer to re-run the function if a deeper equality check could
+potentially be more costly. The `===` equality check is also used internally by
+`Immutable.is` and `.equals()` as a performance optimization.
+
+<!-- runkit:activate -->
+
+```js
+const { Map } = require('immutable');
+const map1 = Map({ a: 1, b: 2, c: 3 });
+const map2 = map1.set('b', 2); // Set to same value
+map1 === map2; // true
+```
+
+If an object is immutable, it can be "copied" simply by making another reference
+to it instead of copying the entire object. Because a reference is much smaller
+than the object itself, this results in memory savings and a potential boost in
+execution speed for programs which rely on copies (such as an undo-stack).
+
+<!-- runkit:activate -->
+
+```js
+const { Map } = require('immutable');
+const map = Map({ a: 1, b: 2, c: 3 });
+const mapCopy = map; // Look, "copies" are free!
+```

+
+
+## JavaScript-first API
+
+While Immutable.js is inspired by Clojure, Scala, Haskell and other functional
+programming environments, it's designed to bring these powerful concepts to
+JavaScript, and therefore has an Object-Oriented API that closely mirrors that
+of [ES2015][] [Array][], [Map][], and [Set][].
+
+[es2015]: https://developer.mozilla.org/en-US/docs/Web/JavaScript/New_in_JavaScript/ECMAScript_6_support_in_Mozilla
+[array]: https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Array
+[map]: https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Map
+[set]: https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Set
+
+The difference for the immutable collections is that methods which would mutate
+the collection, like `push`, `set`, `unshift` or `splice`, instead return a new
+immutable collection. Methods which return new arrays, like `slice` or `concat`,
+instead return new immutable collections.
+
+<!-- runkit:activate -->
+
+```js
+const { List } = require('immutable');
+const list1 = List([1, 2]);
+const list2 = list1.push(3, 4, 5);
+const list3 = list2.unshift(0);
+const list4 = list1.concat(list2, list3);
+assert.equal(list1.size, 2);
+assert.equal(list2.size, 5);
+assert.equal(list3.size, 6);
+assert.equal(list4.size, 13);
+assert.equal(list4.get(0), 1);
+```
+
+Almost all of the methods on [Array][] will be found in similar form on
+`Immutable.List`, those of [Map][] found on `Immutable.Map`, and those of [Set][]
+found on `Immutable.Set`, including collection operations like `forEach()`
+and `map()`.
+
+<!-- runkit:activate -->
+
+```js
+const { Map } = require('immutable');
+const alpha = Map({ a: 1, b: 2, c: 3, d: 4 });
+alpha.map((v, k) => k.toUpperCase()).join();
+// 'A,B,C,D'
+```
+
+### Convert from raw JavaScript objects and arrays.
+
+Designed to inter-operate with your existing JavaScript, Immutable.js
+accepts plain JavaScript Arrays and Objects anywhere a method expects a
+`Collection`.
+
+<!-- runkit:activate -->
+
+```js
+const { Map, List } = require('immutable');
+const map1 = Map({ a: 1, b: 2, c: 3, d: 4 });
+const map2 = Map({ c: 10, a: 20, t: 30 });
+const obj = { d: 100, o: 200, g: 300 };
+const map3 = map1.merge(map2, obj);
+// Map { a: 20, b: 2, c: 10, d: 100, t: 30, o: 200, g: 300 }
+const list1 = List([1, 2, 3]);
+const list2 = List([4, 5, 6]);
+const array = [7, 8, 9];
+const list3 = list1.concat(list2, array);
+// List [ 1, 2, 3, 4, 5, 6, 7, 8, 9 ]
+```
+
+This is possible because Immutable.js can treat any JavaScript Array or Object
+as a Collection. You can take advantage of this in order to get sophisticated
+collection methods on JavaScript Objects, which otherwise have a very sparse
+native API. Because Seq evaluates lazily and does not cache intermediate
+results, these operations can be extremely efficient.
+
+<!-- runkit:activate -->
+
+```js
+const { Seq } = require('immutable');
+const myObject = { a: 1, b: 2, c: 3 };
+Seq(myObject)
+  .map(x => x * x)
+  .toObject();
+// { a: 1, b: 4, c: 9 }
+```
+
+Keep in mind, when using JS objects to construct Immutable Maps, that
+JavaScript Object properties are always strings, even if written in a quote-less
+shorthand, while Immutable Maps accept keys of any type.
+
+<!-- runkit:activate -->
+
+```js
+const { fromJS } = require('immutable');
+
+const obj = { 1: 'one' };
+console.log(Object.keys(obj)); // [ "1" ]
+console.log(obj['1'], obj[1]); // "one", "one"
+
+const map = fromJS(obj);
+console.log(map.get('1'), map.get(1)); // "one", undefined
+```
+
+Property access for JavaScript Objects first converts the key to a string, but
+since Immutable Map keys can be of any type the argument to `get()` is
+not altered.
+
+### Converts back to raw JavaScript objects.
+
+All Immutable.js Collections can be converted to plain JavaScript Arrays and
+Objects shallowly with `toArray()` and `toObject()` or deeply with `toJS()`.
+All Immutable Collections also implement `toJSON()` allowing them to be passed
+to `JSON.stringify` directly. They also respect the custom `toJSON()` methods of
+nested objects.
+
+<!-- runkit:activate -->
+
+```js
+const { Map, List } = require('immutable');
+const deep = Map({ a: 1, b: 2, c: List([3, 4, 5]) });
+console.log(deep.toObject()); // { a: 1, b: 2, c: List [ 3, 4, 5 ] }
+console.log(deep.toArray()); // [ 1, 2, List [ 3, 4, 5 ] ]
+console.log(deep.toJS()); // { a: 1, b: 2, c: [ 3, 4, 5 ] }
+JSON.stringify(deep); // '{"a":1,"b":2,"c":[3,4,5]}'
+```
+
+### Embraces ES2015
+
+Immutable.js supports all JavaScript environments, including legacy
+browsers (even IE11). However it also takes advantage of features added to
+JavaScript in [ES2015][], the latest standard version of JavaScript, including
+[Iterators][], [Arrow Functions][], [Classes][], and [Modules][]. It's inspired
+by the native [Map][] and [Set][] collections added to ES2015.
+
+All examples in the Documentation are presented in ES2015. To run in all
+browsers, they need to be translated to ES5.
+
+```js
+// ES2015
+const mapped = foo.map(x => x * x);
+// ES5
+var mapped = foo.map(function (x) {
+  return x * x;
+});
+```
+
+All Immutable.js collections are [Iterable][iterators], which allows them to be
+used anywhere an Iterable is expected, such as when spreading into an Array.
+
+<!-- runkit:activate -->
+
+```js
+const { List } = require('immutable');
+const aList = List([1, 2, 3]);
+const anArray = [0, ...aList, 4, 5]; // [ 0, 1, 2, 3, 4, 5 ]
+```
+
+Note: A Collection is always iterated in the same order, however that order may
+not always be well defined, as is the case for the `Map` and `Set`.
+
+[Iterators]: https://developer.mozilla.org/en-US/docs/Web/JavaScript/Guide/The_Iterator_protocol
+[Arrow Functions]: https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Functions/Arrow_functions
+[Classes]: https://wiki.ecmascript.org/doku.php?id=strawman:maximally_minimal_classes
+[Modules]: https://www.2ality.com/2014/09/es6-modules-final.html
+
+
+## Nested Structures
+
+The collections in Immutable.js are intended to be nested, allowing for deep
+trees of data, similar to JSON.
+
+<!-- runkit:activate -->
+
+```js
+const { fromJS } = require('immutable');
+const nested = fromJS({ a: { b: { c: [3, 4, 5] } } });
+// Map { a: Map { b: Map { c: List [ 3, 4, 5 ] } } }
+```
+
+A few power-tools allow for reading and operating on nested data. The
+most useful are `mergeDeep`, `getIn`, `setIn`, and `updateIn`, found on `List`,
+`Map` and `OrderedMap`.
+
+<!-- runkit:activate -->
+
+```js
+const { fromJS } = require('immutable');
+const nested = fromJS({ a: { b: { c: [3, 4, 5] } } });
+
+const nested2 = nested.mergeDeep({ a: { b: { d: 6 } } });
+// Map { a: Map { b: Map { c: List [ 3, 4, 5 ], d: 6 } } }
+
+console.log(nested2.getIn(['a', 'b', 'd'])); // 6
+
+const nested3 = nested2.updateIn(['a', 'b', 'd'], value => value + 1);
+console.log(nested3);
+// Map { a: Map { b: Map { c: List [ 3, 4, 5 ], d: 7 } } }
+
+const nested4 = nested3.updateIn(['a', 'b', 'c'], list => list.push(6));
+// Map { a: Map { b: Map { c: List [ 3, 4, 5, 6 ], d: 7 } } }
+```
+
+## Equality treats Collections as Values
+
+Immutable.js collections are treated as pure data _values_. Two immutable
+collections are considered _value equal_ (via `.equals()` or `is()`) if they
+represent the same collection of values. This differs from JavaScript's typical
+_reference equal_ (via `===` or `==`) for Objects and Arrays which only
+determines if two variables represent references to the same object instance.
+
+Consider the example below where two identical `Map` instances are not
+_reference equal_ but are _value equal_.
+
+<!-- runkit:activate -->
+
+```js
+// First consider:
+const obj1 = { a: 1, b: 2, c: 3 };
+const obj2 = { a: 1, b: 2, c: 3 };
+obj1 !== obj2; // two different instances are always not equal with ===
+
+const { Map, is } = require('immutable');
+const map1 = Map({ a: 1, b: 2, c: 3 });
+const map2 = Map({ a: 1, b: 2, c: 3 });
+map1 !== map2; // two different instances are not reference-equal
+map1.equals(map2); // but are value-equal if they have the same values
+is(map1, map2); // alternatively can use the is() function
+```
+
+Value equality allows Immutable.js collections to be used as keys in Maps or
+values in Sets, and retrieved with different but equivalent collections:
+
+<!-- runkit:activate -->
+
+```js
+const { Map, Set } = require('immutable');
+const map1 = Map({ a: 1, b: 2, c: 3 });
+const map2 = Map({ a: 1, b: 2, c: 3 });
+const set = Set().add(map1);
+set.has(map2); // true because these are value-equal
+```
+
+Note: `is()` uses the same measure of equality as [Object.is][] for scalar
+strings and numbers, but uses value equality for Immutable collections,
+determining if both are immutable and all keys and values are equal
+using the same measure of equality.
+
+[object.is]: https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Object/is
+
+#### Performance tradeoffs
+
+While value equality is useful in many circumstances, it has different
+performance characteristics than reference equality. Understanding these
+tradeoffs may help you decide which to use in each case, especially when used
+to memoize some operation.
+
+When comparing two collections, value equality may require considering every
+item in each collection, on an `O(N)` time complexity. For large collections of
+values, this could become a costly operation. Though if the two are not equal
+and hardly similar, the inequality is determined very quickly. In contrast, when
+comparing two collections with reference equality, only the initial references
+to memory need to be compared which is not based on the size of the collections,
+which has an `O(1)` time complexity. Checking reference equality is always very
+fast, however just because two collections are not reference-equal does not rule
+out the possibility that they may be value-equal.
+
+#### Return self on no-op optimization
+
+When possible, Immutable.js avoids creating new objects for updates where no
+change in _value_ occurred, to allow for efficient _reference equality_ checking
+to quickly determine if no change occurred.
+
+<!-- runkit:activate -->
+
+```js
+const { Map } = require('immutable');
+const originalMap = Map({ a: 1, b: 2, c: 3 });
+const updatedMap = originalMap.set('b', 2);
+updatedMap === originalMap; // No-op .set() returned the original reference.
+```
+
+However updates which do result in a change will return a new reference. Each
+of these operations occur independently, so two similar updates will not return
+the same reference:
+
+<!-- runkit:activate -->
+
+```js
+const { Map } = require('immutable');
+const originalMap = Map({ a: 1, b: 2, c: 3 });
+const updatedMap = originalMap.set('b', 1000);
+// New instance, leaving the original immutable.
+updatedMap !== originalMap;
+const anotherUpdatedMap = originalMap.set('b', 1000);
+// Despite both the results of the same operation, each created a new reference.
+anotherUpdatedMap !== updatedMap;
+// However the two are value equal.
+anotherUpdatedMap.equals(updatedMap);
+```
+
+## Batching Mutations
+
+> If a tree falls in the woods, does it make a sound?
+>
+> If a pure function mutates some local data in order to produce an immutable
+> return value, is that ok?
+>
+> — Rich Hickey, Clojure
+
+Applying a mutation to create a new immutable object results in some overhead,
+which can add up to a minor performance penalty. If you need to apply a series
+of mutations locally before returning, Immutable.js gives you the ability to
+create a temporary mutable (transient) copy of a collection and apply a batch of
+mutations in a performant manner by using `withMutations`. In fact, this is
+exactly how Immutable.js applies complex mutations itself.
+
+As an example, building `list2` results in the creation of 1, not 3, new
+immutable Lists.
+
+<!-- runkit:activate -->
+
+```js
+const { List } = require('immutable');
+const list1 = List([1, 2, 3]);
+const list2 = list1.withMutations(function (list) {
+  list.push(4).push(5).push(6);
+});
+assert.equal(list1.size, 3);
+assert.equal(list2.size, 6);
+```
+
+Note: Immutable.js also provides `asMutable` and `asImmutable`, but only
+encourages their use when `withMutations` will not suffice. Use caution to not
+return a mutable copy, which could result in undesired behavior.
+
+_Important!_: Only a select few methods can be used in `withMutations` including
+`set`, `push` and `pop`. These methods can be applied directly against a
+persistent data-structure where other methods like `map`, `filter`, `sort`,
+and `splice` will always return new immutable data-structures and never mutate
+a mutable collection.
+
+## Lazy Seq
+
+`Seq` describes a lazy operation, allowing them to efficiently chain
+use of all the higher-order collection methods (such as `map` and `filter`)
+by not creating intermediate collections.
+
+**Seq is immutable** — Once a Seq is created, it cannot be
+changed, appended to, rearranged or otherwise modified. Instead, any mutative
+method called on a `Seq` will return a new `Seq`.
+
+**Seq is lazy** — `Seq` does as little work as necessary to respond to any
+method call. Values are often created during iteration, including implicit
+iteration when reducing or converting to a concrete data structure such as
+a `List` or JavaScript `Array`.
+
+For example, the following performs no work, because the resulting
+`Seq`'s values are never iterated:
+
+```js
+const { Seq } = require('immutable');
+const oddSquares = Seq([1, 2, 3, 4, 5, 6, 7, 8])
+  .filter(x => x % 2 !== 0)
+  .map(x => x * x);
+```
+
+Once the `Seq` is used, it performs only the work necessary. In this
+example, no intermediate arrays are ever created, filter is called three
+times, and map is only called once:
+
+```js
+oddSquares.get(1); // 9
+```
+
+Any collection can be converted to a lazy Seq with `Seq()`.
+
+<!-- runkit:activate -->
+
+```js
+const { Map, Seq } = require('immutable');
+const map = Map({ a: 1, b: 2, c: 3 });
+const lazySeq = Seq(map);
+```
+
+`Seq` allows for the efficient chaining of operations, allowing for the
+expression of logic that can otherwise be very tedious:
+
+```js
+lazySeq
+  .flip()
+  .map(key => key.toUpperCase())
+  .flip();
+// Seq { A: 1, B: 2, C: 3 }
+```
+
+As well as expressing logic that would otherwise seem memory or time
+limited, for example `Range` is a special kind of Lazy sequence.
+
+<!-- runkit:activate -->
+
+```js
+const { Range } = require('immutable');
+Range(1, Infinity)
+  .skip(1000)
+  .map(n => -n)
+  .filter(n => n % 2 === 0)
+  .take(2)
+  .reduce((r, n) => r * n, 1);
+// 1006008
+```
+
+## Comparison of filter(), groupBy(), and partition()
+
+The `filter()`, `groupBy()`, and `partition()` methods are similar in that they
+all divide a collection into parts based on applying a function to each element.
+All three call the predicate or grouping function once for each item in the
+input collection.  All three return zero or more collections of the same type as
+their input.  The returned collections are always distinct from the input
+(according to `===`), even if the contents are identical.
+
+Of these methods, `filter()` is the only one that is lazy and the only one which
+discards items from the input collection. It is the simplest to use, and the
+fact that it returns exactly one collection makes it easy to combine with other
+methods to form a pipeline of operations.
+
+The `partition()` method is similar to an eager version of `filter()`, but it
+returns two collections; the first contains the items that would have been
+discarded by `filter()`, and the second contains the items that would have been
+kept.  It always returns an array of exactly two collections, which can make it
+easier to use than `groupBy()`.  Compared to making two separate calls to
+`filter()`, `partition()` makes half as many calls it the predicate passed to
+it.
+
+The `groupBy()` method is a more generalized version of `partition()` that can
+group by an arbitrary function rather than just a predicate.  It returns a map
+with zero or more entries, where the keys are the values returned by the
+grouping function, and the values are nonempty collections of the corresponding
+arguments.  Although `groupBy()` is more powerful than `partition()`, it can be
+harder to use because it is not always possible predict in advance how many
+entries the returned map will have and what their keys will be.

+/**
+ * Immutable data encourages pure functions (data-in, data-out) and lends itself
+ * to much simpler application development and enabling techniques from
+ * functional programming such as lazy evaluation.
+ *
+ * While designed to bring these powerful functional concepts to JavaScript, it
+ * presents an Object-Oriented API familiar to Javascript engineers and closely
+ * mirroring that of Array, Map, and Set. It is easy and efficient to convert to
+ * and from plain Javascript types.
+ *
+ * ## How to read these docs
+ *
+ * In order to better explain what kinds of values the Immutable.js API expects
+ * and produces, this documentation is presented in a statically typed dialect of
+ * JavaScript (like [Flow][] or [TypeScript][]). You *don't need* to use these
+ * type checking tools in order to use Immutable.js, however becoming familiar
+ * with their syntax will help you get a deeper understanding of this API.
+ *
+ * **A few examples and how to read them.**
+ *
+ * All methods describe the kinds of data they accept and the kinds of data
+ * they return. For example a function which accepts two numbers and returns
+ * a number would look like this:
+ *
+ * ```js
+ * sum(first: number, second: number): number
+ * ```
+ *
+ * Sometimes, methods can accept different kinds of data or return different
+ * kinds of data, and this is described with a *type variable*, which is
+ * typically in all-caps. For example, a function which always returns the same
+ * kind of data it was provided would look like this:
+ *
+ * ```js
+ * identity<T>(value: T): T
+ * ```
+ *
+ * Type variables are defined with classes and referred to in methods. For
+ * example, a class that holds onto a value for you might look like this:
+ *
+ * ```js
+ * class Box<T> {
+ *   constructor(value: T)
+ *   getValue(): T
+ * }
+ * ```
+ *
+ * In order to manipulate Immutable data, methods that we're used to affecting
+ * a Collection instead return a new Collection of the same type. The type
+ * `this` refers to the same kind of class. For example, a List which returns
+ * new Lists when you `push` a value onto it might look like:
+ *
+ * ```js
+ * class List<T> {
+ *   push(value: T): this
+ * }
+ * ```
+ *
+ * Many methods in Immutable.js accept values which implement the JavaScript
+ * [Iterable][] protocol, and might appear like `Iterable<string>` for something
+ * which represents sequence of strings. Typically in JavaScript we use plain
+ * Arrays (`[]`) when an Iterable is expected, but also all of the Immutable.js
+ * collections are iterable themselves!
+ *
+ * For example, to get a value deep within a structure of data, we might use
+ * `getIn` which expects an `Iterable` path:
+ *
+ * ```
+ * getIn(path: Iterable<string | number>): unknown
+ * ```
+ *
+ * To use this method, we could pass an array: `data.getIn([ "key", 2 ])`.
+ *
+ *
+ * Note: All examples are presented in the modern [ES2015][] version of
+ * JavaScript. Use tools like Babel to support older browsers.
+ *
+ * For example:
+ *
+ * ```js
+ * // ES2015
+ * const mappedFoo = foo.map(x => x * x);
+ * // ES5
+ * var mappedFoo = foo.map(function (x) { return x * x; });
+ * ```
+ *

+ * [Flow]: https://flowtype.org/

+   * A record is similar to a JS object, but enforces a specific set of allowed
+   * string keys, and has default values.
+   *
+   * The `Record()` function produces new Record Factories, which when called
+   * create Record instances.
+   *
+   * ```js
+   * const { Record } = require('immutable')
+   * const ABRecord = Record({ a: 1, b: 2 })
+   * const myRecord = ABRecord({ b: 3 })
+   * ```
+   *
+   * Records always have a value for the keys they define. `remove`ing a key
+   * from a record simply resets it to the default value for that key.
+   *
+   * ```js
+   * myRecord.get('a') // 1
+   * myRecord.get('b') // 3
+   * const myRecordWithoutB = myRecord.remove('b')
+   * myRecordWithoutB.get('b') // 2
+   * ```
+   *
+   * Values provided to the constructor not found in the Record type will
+   * be ignored. For example, in this case, ABRecord is provided a key "x" even
+   * though only "a" and "b" have been defined. The value for "x" will be
+   * ignored for this record.
+   *
+   * ```js
+   * const myRecord = ABRecord({ b: 3, x: 10 })
+   * myRecord.get('x') // undefined
+   * ```
+   *
+   * Because Records have a known set of string keys, property get access works
+   * as expected, however property sets will throw an Error.
+   *
+   * Note: IE8 does not support property access. Only use `get()` when
+   * supporting IE8.
+   *
+   * ```js
+   * myRecord.b // 3
+   * myRecord.b = 5 // throws Error
+   * ```
+   *
+   * Record Types can be extended as well, allowing for custom methods on your
+   * Record. This is not a common pattern in functional environments, but is in
+   * many JS programs.
+   *
+   * However Record Types are more restricted than typical JavaScript classes.
+   * They do not use a class constructor, which also means they cannot use
+   * class properties (since those are technically part of a constructor).
+   *
+   * While Record Types can be syntactically created with the JavaScript `class`
+   * form, the resulting Record function is actually a factory function, not a
+   * class constructor. Even though Record Types are not classes, JavaScript
+   * currently requires the use of `new` when creating new Record instances if
+   * they are defined as a `class`.
+   *
+   * ```
+   * class ABRecord extends Record({ a: 1, b: 2 }) {
+   *   getAB() {
+   *     return this.a + this.b;
+   *   }
+   * }
+   *
+   * var myRecord = new ABRecord({b: 3})
+   * myRecord.getAB() // 4
+   * ```
+   *
+   *
+   * **Flow Typing Records:**
+   *
+   * Immutable.js exports two Flow types designed to make it easier to use
+   * Records with flow typed code, `RecordOf<TProps>` and `RecordFactory<TProps>`.
+   *
+   * When defining a new kind of Record factory function, use a flow type that
+   * describes the values the record contains along with `RecordFactory<TProps>`.
+   * To type instances of the Record (which the factory function returns),
+   * use `RecordOf<TProps>`.
+   *
+   * Typically, new Record definitions will export both the Record factory
+   * function as well as the Record instance type for use in other code.
+   *
+   * ```js
+   * import type { RecordFactory, RecordOf } from 'immutable';
+   *
+   * // Use RecordFactory<TProps> for defining new Record factory functions.
+   * type Point3DProps = { x: number, y: number, z: number };
+   * const defaultValues: Point3DProps = { x: 0, y: 0, z: 0 };
+   * const makePoint3D: RecordFactory<Point3DProps> = Record(defaultValues);
+   * export makePoint3D;
+   *
+   * // Use RecordOf<T> for defining new instances of that Record.
+   * export type Point3D = RecordOf<Point3DProps>;
+   * const some3DPoint: Point3D = makePoint3D({ x: 10, y: 20, z: 30 });
+   * ```
+   *
+   * **Flow Typing Record Subclasses:**
+   *
+   * Records can be subclassed as a means to add additional methods to Record
+   * instances. This is generally discouraged in favor of a more functional API,
+   * since Subclasses have some minor overhead. However the ability to create
+   * a rich API on Record types can be quite valuable.
+   *
+   * When using Flow to type Subclasses, do not use `RecordFactory<TProps>`,
+   * instead apply the props type when subclassing:
+   *
+   * ```js
+   * type PersonProps = {name: string, age: number};
+   * const defaultValues: PersonProps = {name: 'Aristotle', age: 2400};
+   * const PersonRecord = Record(defaultValues);
+   * class Person extends PersonRecord<PersonProps> {
+   *   getName(): string {
+   *     return this.get('name')
+   *   }
+   *
+   *   setName(name: string): this {
+   *     return this.set('name', name);
+   *   }
+   * }
+   * ```
+   *
+   * **Choosing Records vs plain JavaScript objects**
+   *
+   * Records offer a persistently immutable alternative to plain JavaScript
+   * objects, however they're not required to be used within Immutable.js
+   * collections. In fact, the deep-access and deep-updating functions
+   * like `getIn()` and `setIn()` work with plain JavaScript Objects as well.
+   *
+   * Deciding to use Records or Objects in your application should be informed
+   * by the tradeoffs and relative benefits of each:
+   *
+   * - *Runtime immutability*: plain JS objects may be carefully treated as
+   *   immutable, however Record instances will *throw* if attempted to be
+   *   mutated directly. Records provide this additional guarantee, however at
+   *   some marginal runtime cost. While JS objects are mutable by nature, the
+   *   use of type-checking tools like [Flow](https://medium.com/@gcanti/immutability-with-flow-faa050a1aef4)
+   *   can help gain confidence in code written to favor immutability.
+   *
+   * - *Value equality*: Records use value equality when compared with `is()`
+   *   or `record.equals()`. That is, two Records with the same keys and values
+   *   are equal. Plain objects use *reference equality*. Two objects with the
+   *   same keys and values are not equal since they are different objects.
+   *   This is important to consider when using objects as keys in a `Map` or
+   *   values in a `Set`, which use equality when retrieving values.
+   *
+   * - *API methods*: Records have a full featured API, with methods like
+   *   `.getIn()`, and `.equals()`. These can make working with these values
+   *   easier, but comes at the cost of not allowing keys with those names.
+   *
+   * - *Default values*: Records provide default values for every key, which
+   *   can be useful when constructing Records with often unchanging values.
+   *   However default values can make using Flow and TypeScript more laborious.
+   *
+   * - *Serialization*: Records use a custom internal representation to
+   *   efficiently store and update their values. Converting to and from this
+   *   form isn't free. If converting Records to plain objects is common,
+   *   consider sticking with plain objects to begin with.

+   * `Seq` describes a lazy operation, allowing them to efficiently chain
+   * use of all the higher-order collection methods (such as `map` and `filter`)
+   * by not creating intermediate collections.
+   *
+   * **Seq is immutable** — Once a Seq is created, it cannot be
+   * changed, appended to, rearranged or otherwise modified. Instead, any
+   * mutative method called on a `Seq` will return a new `Seq`.
+   *
+   * **Seq is lazy** — `Seq` does as little work as necessary to respond to any
+   * method call. Values are often created during iteration, including implicit
+   * iteration when reducing or converting to a concrete data structure such as
+   * a `List` or JavaScript `Array`.
+   *
+   * For example, the following performs no work, because the resulting
+   * `Seq`'s values are never iterated:
+   *
+   * ```js
+   * const { Seq } = require('immutable')
+   * const oddSquares = Seq([ 1, 2, 3, 4, 5, 6, 7, 8 ])
+   *   .filter(x => x % 2 !== 0)
+   *   .map(x => x * x)
+   * ```
+   *
+   * Once the `Seq` is used, it performs only the work necessary. In this
+   * example, no intermediate arrays are ever created, filter is called three
+   * times, and map is only called once:
+   *
+   * ```js
+   * oddSquares.get(1); // 9
+   * ```
+   *
+   * Any collection can be converted to a lazy Seq with `Seq()`.
+   *
+   * <!-- runkit:activate -->
+   * ```js
+   * const { Map } = require('immutable')
+   * const map = Map({ a: 1, b: 2, c: 3 })
+   * const lazySeq = Seq(map)
+   * ```
+   *
+   * `Seq` allows for the efficient chaining of operations, allowing for the
+   * expression of logic that can otherwise be very tedious:
+   *
+   * ```js
+   * lazySeq
+   *   .flip()
+   *   .map(key => key.toUpperCase())
+   *   .flip()
+   * // Seq { A: 1, B: 1, C: 1 }
+   * ```
+   *
+   * As well as expressing logic that would otherwise seem memory or time
+   * limited, for example `Range` is a special kind of Lazy sequence.
+   *
+   * <!-- runkit:activate -->
+   * ```js
+   * const { Range } = require('immutable')
+   * Range(1, Infinity)
+   *   .skip(1000)
+   *   .map(n => -n)
+   *   .filter(n => n % 2 === 0)
+   *   .take(2)
+   *   .reduce((r, n) => r * n, 1)
+   * // 1006008
+   * ```
+   *
+   * Seq is often used to provide a rich collection API to JavaScript Object.
+   *
+   * ```js
+   * Seq({ x: 0, y: 1, z: 2 }).map(v => v * 2).toObject();
+   * // { x: 0, y: 2, z: 4 }

+   *
+   * <!-- runkit:activate -->

+   * > "", {a: {b: [10, 20, 30]}, c: 40}, []
+   * ```
+   *
+   * Keep in mind, when using JS objects to construct Immutable Maps, that
+   * JavaScript Object properties are always strings, even if written in a
+   * quote-less shorthand, while Immutable Maps accept keys of any type.
+   *
+   * <!-- runkit:activate -->

+ * An extension of the "same-value" algorithm as [described for use by ES6 Map
+ * and Set](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Map#Key_equality)
+ *
+ * NaN is considered the same as NaN, however -0 and 0 are considered the same
+ * value, which is different from the algorithm described by
+ * [`Object.is`](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Object/is).
+ *
+ * This is extended further to allow Objects to describe the values they
+ * represent, by way of `valueOf` or `equals` (and `hashCode`).
+ *
+ * Note: because of this extension, the key equality of Immutable.Map and the
+ * value equality of Immutable.Set will differ from ES6 Map and Set.
+ *
+ * ### Defining custom values
+ *
+ * The easiest way to describe the value an object represents is by implementing
+ * `valueOf`. For example, `Date` represents a value by returning a unix
+ * timestamp for `valueOf`:
+ *
+ *     var date1 = new Date(1234567890000); // Fri Feb 13 2009 ...
+ *     var date2 = new Date(1234567890000);
+ *     date1.valueOf(); // 1234567890000
+ *     assert( date1 !== date2 );
+ *     assert( Immutable.is( date1, date2 ) );
+ *
+ * Note: overriding `valueOf` may have other implications if you use this object
+ * where JavaScript expects a primitive, such as implicit string coercion.
+ *
+ * For more complex types, especially collections, implementing `valueOf` may
+ * not be performant. An alternative is to implement `equals` and `hashCode`.
+ *
+ * `equals` takes another object, presumably of similar type, and returns true
+ * if it is equal. Equality is symmetrical, so the same result should be
+ * returned if this and the argument are flipped.
+ *
+ *     assert( a.equals(b) === b.equals(a) );
+ *
+ * `hashCode` returns a 32bit integer number representing the object which will
+ * be used to determine how to store the value object in a Map or Set. You must
+ * provide both or neither methods, one must not exist without the other.
+ *
+ * Also, an important relationship between these methods must be upheld: if two
+ * values are equal, they *must* return the same hashCode. If the values are not
+ * equal, they might have the same hashCode; this is called a hash collision,
+ * and while undesirable for performance reasons, it is acceptable.
+ *
+ *     if (a.equals(b)) {
+ *       assert( a.hashCode() === b.hashCode() );
+ *     }
+ *
+ * All Immutable collections are Value Objects: they implement `equals()`
+ * and `hashCode()`.

+   * An extension of the "same-value" algorithm as [described for use by ES6 Map
+   * and Set](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Map#Key_equality)
+   *
+   * NaN is considered the same as NaN, however -0 and 0 are considered the same
+   * value, which is different from the algorithm described by
+   * [`Object.is`](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Object/is).
+   *
+   * This is extended further to allow Objects to describe the values they
+   * represent, by way of `valueOf` or `equals` (and `hashCode`).
+   *
+   * Note: because of this extension, the key equality of Immutable.Map and the
+   * value equality of Immutable.Set will differ from ES6 Map and Set.
+   *
+   * ### Defining custom values
+   *
+   * The easiest way to describe the value an object represents is by implementing
+   * `valueOf`. For example, `Date` represents a value by returning a unix
+   * timestamp for `valueOf`:
+   *
+   *     var date1 = new Date(1234567890000); // Fri Feb 13 2009 ...
+   *     var date2 = new Date(1234567890000);
+   *     date1.valueOf(); // 1234567890000
+   *     assert( date1 !== date2 );
+   *     assert( Immutable.is( date1, date2 ) );
+   *
+   * Note: overriding `valueOf` may have other implications if you use this object
+   * where JavaScript expects a primitive, such as implicit string coercion.
+   *
+   * For more complex types, especially collections, implementing `valueOf` may
+   * not be performant. An alternative is to implement `equals` and `hashCode`.
+   *
+   * `equals` takes another object, presumably of similar type, and returns true
+   * if it is equal. Equality is symmetrical, so the same result should be
+   * returned if this and the argument are flipped.
+   *
+   *     assert( a.equals(b) === b.equals(a) );
+   *
+   * `hashCode` returns a 32bit integer number representing the object which will
+   * be used to determine how to store the value object in a Map or Set. You must
+   * provide both or neither methods, one must not exist without the other.
+   *
+   * Also, an important relationship between these methods must be upheld: if two
+   * values are equal, they *must* return the same hashCode. If the values are not
+   * equal, they might have the same hashCode; this is called a hash collision,
+   * and while undesirable for performance reasons, it is acceptable.
+   *
+   *     if (a.equals(b)) {
+   *       assert( a.hashCode() === b.hashCode() );
+   *     }
+   *
+   * All Immutable collections are Value Objects: they implement `equals()`
+   * and `hashCode()`.

+/**
+ * This file provides type definitions for use with the Flow type checker.
+ *
+ * An important caveat when using these definitions is that the types for
+ * `Collection.Keyed`, `Collection.Indexed`, `Seq.Keyed`, and so on are stubs.
+ * When referring to those types, you can get the proper definitions by
+ * importing the types `KeyedCollection`, `IndexedCollection`, `KeyedSeq`, etc.
+ * For example,
+ *
+ *     import { Seq } from 'immutable'
+ *     import type { IndexedCollection, IndexedSeq } from 'immutable'
+ *
+ *     const someSeq: IndexedSeq<number> = Seq.Indexed.of(1, 2, 3)
+ *
+ *     function takesASeq<T, TS: IndexedCollection<T>>(iter: TS): TS {
+ *       return iter.butLast()
+ *     }
+ *
+ *     takesASeq(someSeq)
+ *

-==========

-Detect if we were run as a result of `npm publish`. This is intended to allow you to
-easily have prepublish lifecycle scripts that don't run when you run `npm install`.
-
-```
-$ npm install --save in-publish
-in-publish@1.0.0 node_modules/in-publish
-```
-
-Then edit your package.json to have:
-
-```json
-  "scripts": {
-    "prepublish": "in-publish && thing-I-dont-want-on-dev-install || not-in-publish"
-  }
-```
-
-Now when you run:
-
-```
-$ npm install
-```
-Then `thing-I-dont-want-on-dev-install` won't be run, but...
-
-```
-$ npm publish
-```
-And `thing-I-dont-want-on-dev-install` will be run.
-
-It's worth noting that the `prepublish` lifecycle is _ALSO_ called when you build a tarball, so:
-
-```
-$ npm pack
-```
-
-Will call your `prepublish` lifecycle, but with the examplea above,
-`thing-I-dont-want-on-dev-install` won't be run.
-
-If you want this, you can use another helper included here:
-
-```json
-  "scripts": {
-    "prepublish": "not-in-install && thing-I-dont-want-on-dev-install || in-install"
-  }
-```
-
-The above will run your `thing-I-dont-want-on-dev-install` on `publish` and
-on `pack` but not on `install`.

-Caveat Emptor
-=============
-
-This detects that its running as a part of publish command in a terrible,
-terrible way.  NPM dumps out its config object blindly into the environment
-prior to running commands.  This includes the command line it was invoked
-with.  This module determines if its being run as a result of publish by
-looking at that env var.  This is not a part of the documented npm interface
-and so it is not guarenteed to be stable.

-# isStream
-
-[![Build Status](https://secure.travis-ci.org/rvagg/isstream.png)](http://travis-ci.org/rvagg/isstream)
-
-**Test if an object is a `Stream`**
-
-[![NPM](https://nodei.co/npm/isstream.svg)](https://nodei.co/npm/isstream/)
-
-The missing `Stream.isStream(obj)`: determine if an object is standard Node.js `Stream`. Works for Node-core `Stream` objects (for 0.8, 0.10, 0.11, and in theory, older and newer versions) and all versions of **[readable-stream](https://github.com/isaacs/readable-stream)**.
-
-## Usage:
-
-```js
-var isStream = require('isstream')
-var Stream = require('stream')
-
-isStream(new Stream()) // true
-
-isStream({}) // false
-
-isStream(new Stream.Readable())    // true
-isStream(new Stream.Writable())    // true
-isStream(new Stream.Duplex())      // true
-isStream(new Stream.Transform())   // true
-isStream(new Stream.PassThrough()) // true
-```
-
-## But wait! There's more!
-
-You can also test for `isReadable(obj)`, `isWritable(obj)` and `isDuplex(obj)` to test for implementations of Streams2 (and Streams3) base classes.
-
-```js
-var isReadable = require('isstream').isReadable
-var isWritable = require('isstream').isWritable
-var isDuplex = require('isstream').isDuplex
-var Stream = require('stream')
-
-isReadable(new Stream()) // false
-isWritable(new Stream()) // false
-isDuplex(new Stream())   // false
-
-isReadable(new Stream.Readable())    // true
-isReadable(new Stream.Writable())    // false
-isReadable(new Stream.Duplex())      // true
-isReadable(new Stream.Transform())   // true
-isReadable(new Stream.PassThrough()) // true
-
-isWritable(new Stream.Readable())    // false
-isWritable(new Stream.Writable())    // true
-isWritable(new Stream.Duplex())      // true
-isWritable(new Stream.Transform())   // true
-isWritable(new Stream.PassThrough()) // true
-
-isDuplex(new Stream.Readable())    // false
-isDuplex(new Stream.Writable())    // false
-isDuplex(new Stream.Duplex())      // true
-isDuplex(new Stream.Transform())   // true
-isDuplex(new Stream.PassThrough()) // true
-```
-
-*Reminder: when implementing your own streams, please [use **readable-stream** rather than core streams](http://r.va.gg/2014/06/why-i-dont-use-nodes-core-stream-module.html).*

-# base64.js
-
-Yet another Base64 transcoder
-
-## Install
-
-```javascript
-$ npm install --save js-base64
-```
-
-If you are using it on ES6 transpilers, you may also need:
-
-```javascript
-$ npm install --save babel-preset-env
-```
-
-Note `js-base64` itself is stand-alone so its `package.json` has no `dependencies`.  However, it is also tested on ES6 environment so `"babel-preset-env": "^1.7.0"` is on `devDependencies`.
-
-
-## Usage
-
-### In Browser
-
-```html
-<script src="base64.js"></script>
-```
-
-### node.js
-
-```javascript
-var Base64 = require('js-base64').Base64;
-```
-
-## es6+
-
-```javascript
-import { Base64 } from 'js-base64';
-```
-
-## SYNOPSIS
-
-```javascript
-Base64.encode('dankogai');  // ZGFua29nYWk=
-Base64.encode('小飼弾');    // 5bCP6aO85by+
-Base64.encodeURI('小飼弾'); // 5bCP6aO85by-
-
-Base64.decode('ZGFua29nYWk=');  // dankogai
-Base64.decode('5bCP6aO85by+');  // 小飼弾
-// note .decodeURI() is unnecessary since it accepts both flavors
-Base64.decode('5bCP6aO85by-');  // 小飼弾
-```
-
-### String Extension for ES5
-
-```javascript
-if (Base64.extendString) {
-    // you have to explicitly extend String.prototype
-    Base64.extendString();
-    // once extended, you can do the following
-    'dankogai'.toBase64();       // ZGFua29nYWk=
-    '小飼弾'.toBase64();         // 5bCP6aO85by+
-    '小飼弾'.toBase64(true);     // 5bCP6aO85by-
-    '小飼弾'.toBase64URI();      // 5bCP6aO85by-
-    'ZGFua29nYWk='.fromBase64(); // dankogai
-    '5bCP6aO85by+'.fromBase64(); // 小飼弾
-    '5bCP6aO85by-'.fromBase64(); // 小飼弾
-}
-```
-
-### TypeScript
-
-TypeScript 2.0 type definition was added to the [DefinitelyTyped repository](https://github.com/DefinitelyTyped/DefinitelyTyped).
-
-```bash
-$ npm install --save @types/js-base64
-```
-
-## `.decode()` vs `.atob` (and `.encode()` vs `btoa()`)
-
-Suppose you have:
-
-```
-var pngBase64 = 
-  "iVBORw0KGgoAAAANSUhEUgAAAAEAAAABCAQAAAC1HAwCAAAAC0lEQVR42mNkYAAAAAYAAjCB0C8AAAAASUVORK5CYII=";
-```
-
-Which is a Base64-encoded 1x1 transparent PNG, **DO NOT USE** `Base64.decode(pngBase64)`.  Use `Base64.atob(pngBase64)` instead.  `Base64.decode()` decodes to UTF-8 string while `Base64.atob()` decodes to bytes, which is compatible to browser built-in `atob()` (Which is absent in node.js).  The same rule applies to the opposite direction.

-# jsbn: javascript big number
-
-[Tom Wu's Original Website](http://www-cs-students.stanford.edu/~tjw/jsbn/)
-
-I felt compelled to put this on github and publish to npm. I haven't tested every other big integer library out there, but the few that I have tested in comparison to this one have not even come close in performance. I am aware of the `bi` module on npm, however it has been modified and I wanted to publish the original without modifications. This is jsbn and jsbn2 from Tom Wu's original website above, with the modular pattern applied to prevent global leaks and to allow for use with node.js on the server side.
-
-## usage
-
-    var BigInteger = require('jsbn');
-    
-    var a = new BigInteger('91823918239182398123');
-    alert(a.bitLength()); // 67
-
-
-## API
-
-### bi.toString()
-
-returns the base-10 number as a string
-
-### bi.negate()
-
-returns a new BigInteger equal to the negation of `bi`

-# json-schema-traverse
-Traverse JSON Schema passing each schema object to callback
-
-[![Build Status](https://travis-ci.org/epoberezkin/json-schema-traverse.svg?branch=master)](https://travis-ci.org/epoberezkin/json-schema-traverse)
-[![npm version](https://badge.fury.io/js/json-schema-traverse.svg)](https://www.npmjs.com/package/json-schema-traverse)
-[![Coverage Status](https://coveralls.io/repos/github/epoberezkin/json-schema-traverse/badge.svg?branch=master)](https://coveralls.io/github/epoberezkin/json-schema-traverse?branch=master)
-
-
-## Install
-
-```
-npm install json-schema-traverse
-```
-
-
-## Usage
-
-```javascript
-const traverse = require('json-schema-traverse');
-const schema = {
-  properties: {
-    foo: {type: 'string'},
-    bar: {type: 'integer'}
-  }
-};
-
-traverse(schema, {cb});
-// cb is called 3 times with:
-// 1. root schema
-// 2. {type: 'string'}
-// 3. {type: 'integer'}
-
-// Or:
-
-traverse(schema, {cb: {pre, post}});
-// pre is called 3 times with:
-// 1. root schema
-// 2. {type: 'string'}
-// 3. {type: 'integer'}
-//
-// post is called 3 times with:
-// 1. {type: 'string'}
-// 2. {type: 'integer'}
-// 3. root schema
-
-```
-
-Callback function `cb` is called for each schema object (not including draft-06 boolean schemas), including the root schema, in pre-order traversal. Schema references ($ref) are not resolved, they are passed as is.  Alternatively, you can pass a `{pre, post}` object as `cb`, and then `pre` will be called before traversing child elements, and `post` will be called after all child elements have been traversed.
-
-Callback is passed these parameters:
-
-- _schema_: the current schema object
-- _JSON pointer_: from the root schema to the current schema object
-- _root schema_: the schema passed to `traverse` object
-- _parent JSON pointer_: from the root schema to the parent schema object (see below)
-- _parent keyword_: the keyword inside which this schema appears (e.g. `properties`, `anyOf`, etc.)
-- _parent schema_: not necessarily parent object/array; in the example above the parent schema for `{type: 'string'}` is the root schema
-- _index/property_: index or property name in the array/object containing multiple schemas; in the example above for `{type: 'string'}` the property name is `'foo'`
-
-
-## Traverse objects in all unknown keywords
-
-```javascript
-const traverse = require('json-schema-traverse');
-const schema = {
-  mySchema: {
-    minimum: 1,
-    maximum: 2
-  }
-};
-
-traverse(schema, {allKeys: true, cb});
-// cb is called 2 times with:
-// 1. root schema
-// 2. mySchema
-```
-
-Without option `allKeys: true` callback will be called only with root schema.

-			<t>
-				JSON Schema defines the media type "application/schema+json" for 
-				describing the structure of other
-				JSON documents. JSON Schema is JSON-based and includes facilities 
-				for describing the structure of JSON documents in terms of
-				allowable values, descriptions, and interpreting relations with other resources.
-			</t>
-			<t>
-				JSON Schema format is organized into several separate definitions. The first 
-				definition is the core schema specification. This definition is primary 
-				concerned with describing a JSON structure and specifying valid elements
-				in the structure. The second definition is the Hyper Schema specification
-				which is intended define elements in a structure that can be interpreted as
-				hyperlinks.
-				Hyper Schema builds on JSON Schema to describe the hyperlink structure of 
-				other JSON documents and elements of interaction. This allows user agents to be able to successfully navigate
-				JSON documents based on their schemas.
-			</t>
-			<t>
-				Cumulatively JSON Schema acts as a meta-document that can be used to define the required type and constraints on
-				property values, as well as define the meaning of the property values
-				for the purpose of describing a resource and determining hyperlinks
-				within the representation.

-					This schema defines the properties of the instance JSON documents, 
-					the required properties (id, name, and price), as well as an optional
-					property (tags). This also defines the link relations of the instance
-					JSON documents.
-				</postamble>
-			</figure>
-			
-			<section title="Terminology">
-				<t>
-					For this specification, <spanx style="strong">schema</spanx> will be used to denote a JSON Schema 
-					definition, and an <spanx style="strong">instance</spanx> refers to a JSON value that the schema 
-					will be describing and validating.
-				</t>
-			</section>
-			
-			<section title="Design Considerations">
-				<t>
-					The JSON Schema media type does not attempt to dictate the structure of JSON
-					representations that contain data, but rather provides a separate format
-					for flexibly communicating how a JSON representation should be
-					interpreted and validated, such that user agents can properly understand
-					acceptable structures and extrapolate hyperlink information
-					with the JSON document. It is acknowledged that JSON documents come
-					in a variety of structures, and JSON is unique in that the structure
-					of stored data structures often prescribes a non-ambiguous definite
-					JSON representation. Attempting to force a specific structure is generally
-					not viable, and therefore JSON Schema allows for a great flexibility
-					in the structure of the JSON data that it describes.
-				</t>
-				<t>
-					This specification is protocol agnostic.
-					The underlying protocol (such as HTTP) should sufficiently define the
-					semantics of the client-server interface, the retrieval of resource
-					representations linked to by JSON representations, and modification of 
-					those resources. The goal of this
-					format is to sufficiently describe JSON structures such that one can
-					utilize existing information available in existing JSON
-					representations from a large variety of services that leverage a representational state transfer
-					architecture using existing protocols.
-				</t>
-			</section>
-		</section>
-		
-		<section title="Schema/Instance Association">
-			<t>
-				JSON Schema instances are correlated to their schema by the "describedby"
-				relation, where the schema is defined to be the target of the relation.
-				Instance representations may be of the "application/json" media type or
-				any other subtype. Consequently, dictating how an instance
-				representation should specify the relation to the schema is beyond the normative scope
-				of this document (since this document specifically defines the JSON
-				Schema media type, and no other), but it is recommended that instances
-				specify their schema so that user agents can interpret the instance
-				representation and messages may retain the self-descriptive
-				characteristic, avoiding the need for out-of-band information about
-				instance data. Two approaches are recommended for declaring the
-				relation to the schema that describes the meaning of a JSON instance's (or collection 
-				of instances) structure. A MIME type parameter named
-				"profile" or a relation of "describedby" (which could be defined by a Link header) may be used:
-				
-				<figure>
-					<artwork>
-<![CDATA[	
-Content-Type: application/my-media-type+json;
-              profile=http://json.com/my-hyper-schema
-]]>
-					</artwork>
-				</figure>
-				
-				or if the content is being transferred by a protocol (such as HTTP) that
-				provides headers, a Link header can be used:
-				
-				<figure>
-					<artwork>
-<![CDATA[
-Link: <http://json.com/my-hyper-schema>; rel="describedby"
-]]>
-					</artwork>
-				</figure>
-				
-				Instances MAY specify multiple schemas, to indicate all the schemas that 
-				are applicable to the data, and the data SHOULD be valid by all the schemas. 
-				The instance data MAY have multiple schemas 
-				that it is defined by (the instance data SHOULD be valid for those schemas). 
-				Or if the document is a collection of instances, the collection MAY contain 
-				instances from different schemas. When collections contain heterogeneous 
-				instances, the "pathStart" attribute MAY be specified in the 
-				schema to disambiguate which schema should be applied for each item in the 
-				collection. However, ultimately, the mechanism for referencing a schema is up to the
-				media type of the instance documents (if they choose to specify that schemas
-				can be referenced).
-			</t>
-			
-			<section title="Self-Descriptive Schema">
-				<t>
-					JSON Schemas can themselves be described using JSON Schemas. 
-					A self-describing JSON Schema for the core JSON Schema can
-					be found at <eref target="http://json-schema.org/schema">http://json-schema.org/schema</eref> for the latest version or 
-					<eref target="http://json-schema.org/draft-03/schema">http://json-schema.org/draft-03/schema</eref> for the draft-03 version. The hyper schema 
-					self-description can be found at <eref target="http://json-schema.org/hyper-schema">http://json-schema.org/hyper-schema</eref> 
-					or <eref target="http://json-schema.org/draft-03/hyper-schema">http://json-schema.org/draft-03/hyper-schema</eref>. All schemas
-					used within a protocol with media type definitions
-					SHOULD include a MIME parameter that refers to the self-descriptive
-					hyper schema or another schema that extends this hyper schema:

-					<t>
-						A link description object is used to describe link relations. In 
-						the context of a schema, it defines the link relations of the 
-						instances of the schema, and can be parameterized by the instance
-						values. The link description format can be used on its own in
-						regular (non-schema documents), and use of this format can
-						be declared by referencing the normative link description
-						schema as the the schema for the data structure that uses the 
-						links. The URI of the normative link description schema is: 
-						<eref target="http://json-schema.org/links">http://json-schema.org/links</eref> (latest version) or
-						<eref target="http://json-schema.org/draft-03/links">http://json-schema.org/draft-03/links</eref> (draft-03 version).
-					</t>
-					
-					<section title="href">
-						<t>
-							The value of the "href" link description property
-							indicates the target URI of the related resource. The value
-							of the instance property SHOULD be resolved as a URI-Reference per <xref target="RFC3986">RFC 3986</xref>
-							and MAY be a relative URI. The base URI to be used for relative resolution
-							SHOULD be the URI used to retrieve the instance object (not the schema)
-							when used within a schema. Also, when links are used within a schema, the URI 
-							SHOULD be parametrized by the property values of the instance 
-							object, if property values exist for the corresponding variables
-							in the template (otherwise they MAY be provided from alternate sources, like user input).
-						</t>
-						
-						<t>
-							Instance property values SHOULD be substituted into the URIs where
-							matching braces ('{', '}') are found surrounding zero or more characters,
-							creating an expanded URI. Instance property value substitutions are resolved
-							by using the text between the braces to denote the property name
-							from the instance to get the value to substitute. 
-							
-							<figure>

-							
-							If matching braces are found with the string "@" (no quotes) between the braces, then the

-							boolean, or number), and not for objects or arrays.
-						</t>
-					</section>
-					
-					<section title="rel">
-						<t>
-							The value of the "rel" property indicates the name of the 
-							relation to the target resource. The relation to the target SHOULD be interpreted as specifically from the instance object that the schema (or sub-schema) applies to, not just the top level resource that contains the object within its hierarchy. If a resource JSON representation contains a sub object with a property interpreted as a link, that sub-object holds the relation with the target. A relation to target from the top level resource MUST be indicated with the schema describing the top level JSON representation.
-						</t>
-						
-						<t>
-							Relationship definitions SHOULD NOT be media type dependent, and users are encouraged to utilize existing accepted relation definitions, including those in existing relation registries (see <xref target="RFC4287">RFC 4287</xref>). However, we define these relations here for clarity of normative interpretation within the context of JSON hyper schema defined relations:

-						is a series of unreserved or escaped URI characters. Each property
-						reference token SHOULD be interpreted, starting from the beginning of
-						the fragment identifier, as a path reference in the target JSON
-						structure. The final target value of the fragment can be determined by
-						starting with the root of the JSON structure from the representation of
-						the resource identified by the pre-fragment URI. If the target is a JSON
-						object, then the new target is the value of the property with the name
-						identified by the next property reference token in the fragment. If the
-						target is a JSON array, then the target is determined by finding the

-			<t>
-				JSON Schema defines the media type "application/schema+json" for 
-				describing the structure of JSON text. JSON Schemas are also written in JSON and includes facilities 
-				for describing the structure of JSON in terms of
-				allowable values, descriptions, and interpreting relations with other resources.
-			</t>
-			<t>
-				This document is organized into several separate definitions. The first 
-				definition is the core schema specification. This definition is primary 
-				concerned with describing a JSON structure and specifying valid elements
-				in the structure. The second definition is the Hyper Schema specification
-				which is intended to define elements in a structure that can be interpreted as
-				hyperlinks.
-				Hyper Schema builds on JSON Schema to describe the hyperlink structure of 
-				JSON values. This allows user agents to be able to successfully navigate
-				documents containing JSON based on their schemas.
-			</t>
-			<t>
-				Cumulatively JSON Schema acts as meta-JSON that can be used to define the 
-				required type and constraints on JSON values, as well as define the meaning
-				of the JSON values for the purpose of describing a resource and determining
-				hyperlinks within the representation. 
-			</t>

-				<preamble>An example JSON Schema that describes products might look like:</preamble>
-				<artwork>
-<![CDATA[	
-{
-	"title": "Product",
-	"properties": {
-		"id": {
-			"title": "Product Identifier",
-			"type": "number"
-		},

-			"title": "Product Name",
-			"type": "string"
-		},

-				<postamble>
-					This schema defines the properties of the instance, 
-					the required properties (id, name, and price), as well as an optional
-					property (tags). This also defines the link relations of the instance.
-				</postamble>
-			</figure>
-			
-			<section title="Design Considerations">
-				<t>
-					The JSON Schema media type does not attempt to dictate the structure of JSON
-					values that contain data, but rather provides a separate format
-					for flexibly communicating how a JSON value should be
-					interpreted and validated, such that user agents can properly understand
-					acceptable structures and extrapolate hyperlink information
-					from the JSON. It is acknowledged that JSON values come
-					in a variety of structures, and JSON is unique in that the structure
-					of stored data structures often prescribes a non-ambiguous definite
-					JSON representation. Attempting to force a specific structure is generally
-					not viable, and therefore JSON Schema allows for a great flexibility
-					in the structure of the JSON data that it describes.
-				</t>
-				<t>
-					This specification is protocol agnostic.
-					The underlying protocol (such as HTTP) should sufficiently define the
-					semantics of the client-server interface, the retrieval of resource
-					representations linked to by JSON representations, and modification of 
-					those resources. The goal of this
-					format is to sufficiently describe JSON structures such that one can
-					utilize existing information available in existing JSON
-					representations from a large variety of services that leverage a representational state transfer
-					architecture using existing protocols.
-				</t>
-			</section>
-		</section>

-		<section title="Schema/Instance Association">
-			<t>
-				JSON values are correlated to their schema by the "describedby"
-				relation, where the schema is the target of the relation.
-				JSON values MUST be of the "application/json" media type or
-				any other subtype. Consequently, dictating how a JSON value should 
-				specify the relation to the schema is beyond the normative scope
-				of this document since this document specifically defines the JSON
-				Schema media type, and no other. It is RECOMMNENDED that JSON values
-				specify their schema so that user agents can interpret the instance
-				and retain the self-descriptive	characteristics. This avoides the need for out-of-band information about
-				instance data. Two approaches are recommended for declaring the
-				relation to the schema that describes the meaning of a JSON instance's (or collection 
-				of instances) structure. A MIME type parameter named
-				"profile" or a relation of "describedby" (which could be specified by a Link header) may be used:
-				
-				<figure>
-					<artwork>
-<![CDATA[	
-Content-Type: application/my-media-type+json;
-              profile=http://example.com/my-hyper-schema
-]]>
-					</artwork>
-				</figure>
-				
-				or if the content is being transferred by a protocol (such as HTTP) that
-				provides headers, a Link header can be used:
-				
-				<figure>
-					<artwork>
-<![CDATA[
-Link: <http://example.com/my-hyper-schema>; rel="describedby"
-]]>
-					</artwork>
-				</figure>
-				
-				Instances MAY specify multiple schemas, to indicate all the schemas that 
-				are applicable to the data, and the data SHOULD be valid by all the schemas. 
-				The instance data MAY have multiple schemas 
-				that it is described by (the instance data SHOULD be valid for those schemas). 
-				Or if the document is a collection of instances, the collection MAY contain 
-				instances from different schemas. The mechanism for referencing a schema is 
-				determined by the media type of the instance (if it provides a method for 
-				referencing schemas).
-			</t>
-			
-			<section title="Self-Descriptive Schema">
-				<t>
-					JSON Schemas can themselves be described using JSON Schemas. 
-					A self-describing JSON Schema for the core JSON Schema can
-					be found at <eref target="http://json-schema.org/schema">http://json-schema.org/schema</eref> for the latest version or 
-					<eref target="http://json-schema.org/draft-04/schema">http://json-schema.org/draft-04/schema</eref> for the draft-04 version. The hyper schema 
-					self-description can be found at <eref target="http://json-schema.org/hyper-schema">http://json-schema.org/hyper-schema</eref> 
-					or <eref target="http://json-schema.org/draft-04/hyper-schema">http://json-schema.org/draft-04/hyper-schema</eref>. All schemas
-					used within a protocol with a media type specified SHOULD include a MIME parameter that refers to the self-descriptive
-					hyper schema or another schema that extends this hyper schema:

-				
-				<section title="Link Description Object">
-					<t>
-						A link description object is used to describe link relations. In 
-						the context of a schema, it defines the link relations of the 
-						instances of the schema, and can be parameterized by the instance
-						values. The link description format can be used without JSON Schema, 
-						and use of this format can
-						be declared by referencing the normative link description
-						schema as the the schema for the data structure that uses the 
-						links. The URI of the normative link description schema is: 
-						<eref target="http://json-schema.org/links">http://json-schema.org/links</eref> (latest version) or
-						<eref target="http://json-schema.org/draft-04/links">http://json-schema.org/draft-04/links</eref> (draft-04 version).
-					</t>
-					
-					<section title="href" anchor="href">
-						<t>
-							The value of the "href" link description property
-							indicates the target URI of the related resource. The value
-							of the instance property SHOULD be resolved as a URI-Reference per <xref target="RFC3986">RFC 3986</xref>
-							and MAY be a relative URI. The base URI to be used for relative resolution
-							SHOULD be the URI used to retrieve the instance object (not the schema)
-							when used within a schema. Also, when links are used within a schema, the URI 
-							SHOULD be parametrized by the property values of the instance 
-							object, if property values exist for the corresponding variables
-							in the template (otherwise they MAY be provided from alternate sources, like user input).
-						</t>
-						
-						<t>
-							Instance property values SHOULD be substituted into the URIs where
-							matching braces ('{', '}') are found surrounding zero or more characters,
-							creating an expanded URI. Instance property value substitutions are resolved
-							by using the text between the braces to denote the property name
-							from the instance to get the value to substitute. 
-							
-							<figure>
-								<preamble>For example, if an href value is defined:</preamble>
-								<artwork>
-<![CDATA[
-http://somesite.com/{id}
-]]>
-								</artwork>
-								<postamble>Then it would be resolved by replace the value of the "id" property value from the instance object.</postamble>
-							</figure>
-							
-							<figure>
-								<preamble>If the value of the "id" property was "45", the expanded URI would be:</preamble>
-								<artwork>
-<![CDATA[
-http://somesite.com/45
-]]>
-								</artwork>
-							</figure>
-							
-							If matching braces are found with the string "@" (no quotes) between the braces, then the 
-							actual instance value SHOULD be used to replace the braces, rather than a property value.
-							This should only be used in situations where the instance is a scalar (string, 
-							boolean, or number), and not for objects or arrays.
-						</t>
-					</section>
-					
-					<section title="rel">
-						<t>
-							The value of the "rel" property indicates the name of the 
-							relation to the target resource. The relation to the target SHOULD be interpreted as specifically from the instance object that the schema (or sub-schema) applies to, not just the top level resource that contains the object within its hierarchy. If a resource JSON representation contains a sub object with a property interpreted as a link, that sub-object holds the relation with the target. A relation to target from the top level resource MUST be indicated with the schema describing the top level JSON representation.
-						</t>
-						
-						<t>
-							Relationship definitions SHOULD NOT be media type dependent, and users are encouraged to utilize existing accepted relation definitions, including those in existing relation registries (see <xref target="RFC4287">RFC 4287</xref>). However, we define these relations here for clarity of normative interpretation within the context of JSON hyper schema defined relations:
-							
-							<list style="hanging">
-								<t hangText="self">
-									If the relation value is "self", when this property is encountered in
-									the instance object, the object represents a resource and the instance object is
-									treated as a full representation of the target resource identified by
-									the specified URI.
-								</t>
-								
-								<t hangText="full">
-									This indicates that the target of the link is the full representation for the instance object. The object that contains this link possibly may not be the full representation.
-								</t>
-								
-								<t hangText="describedby">
-									This indicates the target of the link is the schema for the instance object. This MAY be used to specifically denote the schemas of objects within a JSON object hierarchy, facilitating polymorphic type data structures.
-								</t>
-								
-								<t hangText="root">
-									This relation indicates that the target of the link
-									SHOULD be treated as the root or the body of the representation for the
-									purposes of user agent interaction or fragment resolution. All other
-									properties of the instance objects can be regarded as meta-data
-									descriptions for the data.
-								</t>
-							</list>
-						</t>
-						
-						<t>
-							The following relations are applicable for schemas (the schema as the "from" resource in the relation):
-
-							<list style="hanging">
-								<t hangText="instances">This indicates the target resource that represents collection of instances of a schema.</t>
-								<t hangText="create">This indicates a target to use for creating new instances of a schema. This link definition SHOULD be a submission link with a non-safe method (like POST).</t>

-				SHOULD NOT consider the representation to be the authoritative representation
-				of the resource denoted by the target URI if the target URI is not
-				equivalent to or a sub-path of the the URI used to request the resource 
-				representation which contains the target URI with the "self" link.

-## Unreleased
-- Fixes stringify to only take ancestors into account when checking
-  circularity.  
-  It previously assumed every visited object was circular which led to [false
-  positives][issue9].  
-  Uses the tiny serializer I wrote for [Must.js][must] a year and a half ago.
-- Fixes calling the `replacer` function in the proper context (`thisArg`).
-- Fixes calling the `cycleReplacer` function in the proper context (`thisArg`).
-- Speeds serializing by a factor of
-  Big-O(h-my-god-it-linearly-searched-every-object) it had ever seen. Searching
-  only the ancestors for a circular references speeds up things considerably.

-# json-stringify-safe
-
-Like JSON.stringify, but doesn't throw on circular references.
-
-## Usage
-
-Takes the same arguments as `JSON.stringify`.
-
-```javascript
-var stringify = require('json-stringify-safe');
-var circularObj = {};
-circularObj.circularRef = circularObj;
-circularObj.list = [ circularObj, circularObj ];
-console.log(stringify(circularObj, null, 2));
-```
-
-Output:
-
-```json
-{
-  "circularRef": "[Circular]",
-  "list": [
-    "[Circular]",
-    "[Circular]"
-  ]
-}
-```
-
-## Details
-
-```
-stringify(obj, serializer, indent, decycler)
-```
-
-The first three arguments are the same as to JSON.stringify.  The last
-is an argument that's only used when the object has been seen already.
-
-The default `decycler` function returns the string `'[Circular]'`.
-If, for example, you pass in `function(k,v){}` (return nothing) then it
-will prune cycles.  If you pass in `function(k,v){ return {foo: 'bar'}}`,
-then cyclical objects will always be represented as `{"foo":"bar"}` in
-the result.
-
-```
-stringify.getSerialize(serializer, decycler)
-```
-
-Returns a serializer that can be used elsewhere.  This is the actual
-function that's passed to JSON.stringify.
-
-**Note** that the function returned from `getSerialize` is stateful for now, so
-do **not** use it more than once.

-# jsprim: utilities for primitive JavaScript types
-
-This module provides miscellaneous facilities for working with strings,
-numbers, dates, and objects and arrays of these basic types.
-
-
-### deepCopy(obj)
-
-Creates a deep copy of a primitive type, object, or array of primitive types.
-
-
-### deepEqual(obj1, obj2)
-
-Returns whether two objects are equal.
-
-
-### isEmpty(obj)
-
-Returns true if the given object has no properties and false otherwise.  This
-is O(1) (unlike `Object.keys(obj).length === 0`, which is O(N)).
-
-### hasKey(obj, key)
-
-Returns true if the given object has an enumerable, non-inherited property
-called `key`.  [For information on enumerability and ownership of properties, see
-the MDN
-documentation.](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Enumerability_and_ownership_of_properties)
-
-### forEachKey(obj, callback)
-
-Like Array.forEach, but iterates enumerable, owned properties of an object
-rather than elements of an array.  Equivalent to:
-
-    for (var key in obj) {
-            if (Object.prototype.hasOwnProperty.call(obj, key)) {
-                    callback(key, obj[key]);
-            }
-    }
-
-
-### flattenObject(obj, depth)
-
-Flattens an object up to a given level of nesting, returning an array of arrays
-of length "depth + 1", where the first "depth" elements correspond to flattened
-columns and the last element contains the remaining object .  For example:
-
-    flattenObject({
-        'I': {
-            'A': {
-                'i': {
-                    'datum1': [ 1, 2 ],
-                    'datum2': [ 3, 4 ]
-                },
-                'ii': {

-
-This function is strict: "depth" must be a non-negative integer and "obj" must
-be a non-null object with at least "depth" levels of nesting under all keys.
-
-
-### flattenIter(obj, depth, func)
-
-This is similar to `flattenObject` except that instead of returning an array,
-this function invokes `func(entry)` for each `entry` in the array that
-`flattenObject` would return.  `flattenIter(obj, depth, func)` is logically
-equivalent to `flattenObject(obj, depth).forEach(func)`.  Importantly, this
-version never constructs the full array.  Its memory usage is O(depth) rather
-than O(n) (where `n` is the number of flattened elements).
-
-There's another difference between `flattenObject` and `flattenIter` that's
-related to the special case where `depth === 0`.  In this case, `flattenObject`
-omits the array wrapping `obj` (which is regrettable).
-
-
-### pluck(obj, key)
-
-Fetch nested property "key" from object "obj", traversing objects as needed.
-For example, `pluck(obj, "foo.bar.baz")` is roughly equivalent to
-`obj.foo.bar.baz`, except that:
-
-1. If traversal fails, the resulting value is undefined, and no error is
-   thrown.  For example, `pluck({}, "foo.bar")` is just undefined.
-2. If "obj" has property "key" directly (without traversing), the
-   corresponding property is returned.  For example,
-   `pluck({ 'foo.bar': 1 }, 'foo.bar')` is 1, not undefined.  This is also
-   true recursively, so `pluck({ 'a': { 'foo.bar': 1 } }, 'a.foo.bar')` is
-   also 1, not undefined.
-
-
-### randElt(array)
-
-Returns an element from "array" selected uniformly at random.  If "array" is
-empty, throws an Error.
-
-
-### startsWith(str, prefix)
-
-Returns true if the given string starts with the given prefix and false
-otherwise.
-
-
-### endsWith(str, suffix)
-
-Returns true if the given string ends with the given suffix and false
-otherwise.
-
-
-### parseInteger(str, options)
-
-Parses the contents of `str` (a string) as an integer. On success, the integer
-value is returned (as a number). On failure, an error is **returned** describing
-why parsing failed.
-
-By default, leading and trailing whitespace characters are not allowed, nor are
-trailing characters that are not part of the numeric representation. This
-behaviour can be toggled by using the options below. The empty string (`''`) is
-not considered valid input. If the return value cannot be precisely represented
-as a number (i.e., is smaller than `Number.MIN_SAFE_INTEGER` or larger than
-`Number.MAX_SAFE_INTEGER`), an error is returned. Additionally, the string
-`'-0'` will be parsed as the integer `0`, instead of as the IEEE floating point
-value `-0`.
-
-This function accepts both upper and lowercase characters for digits, similar to
-`parseInt()`, `Number()`, and [strtol(3C)](https://illumos.org/man/3C/strtol).
-
-The following may be specified in `options`:
-
-Option             | Type    | Default | Meaning
------------------- | ------- | ------- | ---------------------------
-base               | number  | 10      | numeric base (radix) to use, in the range 2 to 36
-allowSign          | boolean | true    | whether to interpret any leading `+` (positive) and `-` (negative) characters
-allowImprecise     | boolean | false   | whether to accept values that may have lost precision (past `MAX_SAFE_INTEGER` or below `MIN_SAFE_INTEGER`)
-allowPrefix        | boolean | false   | whether to interpret the prefixes `0b` (base 2), `0o` (base 8), `0t` (base 10), or `0x` (base 16)
-allowTrailing      | boolean | false   | whether to ignore trailing characters
-trimWhitespace     | boolean | false   | whether to trim any leading or trailing whitespace/line terminators
-leadingZeroIsOctal | boolean | false   | whether a leading zero indicates octal
-
-Note that if `base` is unspecified, and `allowPrefix` or `leadingZeroIsOctal`
-are, then the leading characters can change the default base from 10. If `base`
-is explicitly specified and `allowPrefix` is true, then the prefix will only be
-accepted if it matches the specified base. `base` and `leadingZeroIsOctal`
-cannot be used together.
-
-**Context:** It's tricky to parse integers with JavaScript's built-in facilities
-for several reasons:
-
-- `parseInt()` and `Number()` by default allow the base to be specified in the
-  input string by a prefix (e.g., `0x` for hex).
-- `parseInt()` allows trailing nonnumeric characters.
-- `Number(str)` returns 0 when `str` is the empty string (`''`).
-- Both functions return incorrect values when the input string represents a
-  valid integer outside the range of integers that can be represented precisely.
-  Specifically, `parseInt('9007199254740993')` returns 9007199254740992.
-- Both functions always accept `-` and `+` signs before the digit.
-- Some older JavaScript engines always interpret a leading 0 as indicating
-  octal, which can be surprising when parsing input from users who expect a
-  leading zero to be insignificant.
-
-While each of these may be desirable in some contexts, there are also times when
-none of them are wanted. `parseInteger()` grants greater control over what
-input's permissible.
-
-### iso8601(date)
-
-Converts a Date object to an ISO8601 date string of the form
-"YYYY-MM-DDTHH:MM:SS.sssZ".  This format is not customizable.
-
-
-### parseDateTime(str)
-
-Parses a date expressed as a string, as either a number of milliseconds since
-the epoch or any string format that Date accepts, giving preference to the
-former where these two sets overlap (e.g., strings containing small numbers).
-
-
-### hrtimeDiff(timeA, timeB)
-
-Given two hrtime readings (as from Node's `process.hrtime()`), where timeA is
-later than timeB, compute the difference and return that as an hrtime.  It is
-illegal to invoke this for a pair of times where timeB is newer than timeA.
-
-### hrtimeAdd(timeA, timeB)
-
-Add two hrtime intervals (as from Node's `process.hrtime()`), returning a new
-hrtime interval array.  This function does not modify either input argument.
-
-
-### hrtimeAccum(timeA, timeB)
-
-Add two hrtime intervals (as from Node's `process.hrtime()`), storing the
-result in `timeA`.  This function overwrites (and returns) the first argument
-passed in.
-
-
-### hrtimeNanosec(timeA), hrtimeMicrosec(timeA), hrtimeMillisec(timeA)
-
-This suite of functions converts a hrtime interval (as from Node's
-`process.hrtime()`) into a scalar number of nanoseconds, microseconds or
-milliseconds.  Results are truncated, as with `Math.floor()`.
-
-
-### validateJsonObject(schema, object)
-
-Uses JSON validation (via JSV) to validate the given object against the given
-schema.  On success, returns null.  On failure, *returns* (does not throw) a
-useful Error object.
-
-
-### extraProperties(object, allowed)
-
-Check an object for unexpected properties.  Accepts the object to check, and an
-array of allowed property name strings.  If extra properties are detected, an
-array of extra property names is returned.  If no properties other than those
-in the allowed list are present on the object, the returned array will be of
-zero length.
-
-### mergeObjects(provided, overrides, defaults)
-
-Merge properties from objects "provided", "overrides", and "defaults".  The
-intended use case is for functions that accept named arguments in an "args"
-object, but want to provide some default values and override other values.  In
-that case, "provided" is what the caller specified, "overrides" are what the
-function wants to override, and "defaults" contains default values.
-
-The function starts with the values in "defaults", overrides them with the
-values in "provided", and then overrides those with the values in "overrides".
-For convenience, any of these objects may be falsey, in which case they will be
-ignored.  The input objects are never modified, but properties in the returned
-object are not deep-copied.
-
-For example:
-
-    mergeObjects(undefined, { 'objectMode': true }, { 'highWaterMark': 0 })
-
-returns:
-
-    { 'objectMode': true, 'highWaterMark': 0 }
-
-For another example:
-
-    mergeObjects(
-        { 'highWaterMark': 16, 'objectMode': 7 }, /* from caller */
-        { 'objectMode': true },                   /* overrides */
-        { 'highWaterMark': 0 });                  /* default */
-
-returns:
-
-    { 'objectMode': true, 'highWaterMark': 16 }

-
-> Make unhandled promise rejections fail loudly instead of the default [silent fail](https://gist.github.com/benjamingr/0237932cee84712951a2)
-
-By default, promises fail silently if you don't attach a `.catch()` handler to them.
-
-Use this in top-level things like tests, CLI tools, apps, etc, **but not in reusable modules.**<br>
-Not needed in the browser as unhandled promises are shown in the console.
-
-
-## Install
-
-```
-$ npm install --save loud-rejection
-```
-
-
-## Usage
-
-```js
-const loudRejection = require('loud-rejection');
-const promiseFn = require('promise-fn');
-
-// Install the unhandledRejection listeners
-loudRejection();
-
-promiseFn();
-```
-
-Without this module it's more verbose and you might even miss some that will fail silently:
-
-```js
-const promiseFn = require('promise-fn');
-
-function error(err) {
-	console.error(err.stack);
-	process.exit(1);
-}
-
-promiseFn().catch(error);
-```
-
-### Register script
-
-Alternatively to the above, you may simply require `loud-rejection/register` and the unhandledRejection listener will be automagically installed for you.
-
-This is handy for ES2015 imports:
-
-```js
-import 'loud-rejection/register';
-```
-
-
-## API
-
-### loudRejection([log])
-
-#### log
-
-Type: `Function`<br>
-Default: `console.error`
-
-Custom logging function to print the rejected promise. Receives the error stack.

-# object-assign [![Build Status](https://travis-ci.org/sindresorhus/object-assign.svg?branch=master)](https://travis-ci.org/sindresorhus/object-assign)
-
-> ES2015 [`Object.assign()`](http://www.2ality.com/2014/01/object-assign.html) [ponyfill](https://ponyfill.com)
-
-
-## Use the built-in
-
-Node.js 4 and up, as well as every evergreen browser (Chrome, Edge, Firefox, Opera, Safari),
-support `Object.assign()` :tada:. If you target only those environments, then by all
-means, use `Object.assign()` instead of this package.
-
-
-## Install
-
-```
-$ npm install --save object-assign
-```
-
-
-## Usage
-
-```js
-const objectAssign = require('object-assign');
-
-objectAssign({foo: 0}, {bar: 1});
-//=> {foo: 0, bar: 1}
-
-// multiple sources
-objectAssign({foo: 0}, {bar: 1}, {baz: 2});
-//=> {foo: 0, bar: 1, baz: 2}
-
-// overwrites equal keys
-objectAssign({foo: 0}, {foo: 1}, {foo: 2});
-//=> {foo: 2}
-
-// ignores null and undefined sources
-objectAssign({foo: 0}, null, {bar: 1}, undefined);
-//=> {foo: 0, bar: 1}
-```
-
-
-## API
-
-### objectAssign(target, [source, ...])
-
-Assigns enumerable own properties of `source` objects to the `target` object and returns the `target` object. Additional `source` objects will overwrite previous ones.

-# meow [![Build Status](https://travis-ci.org/sindresorhus/meow.svg?branch=master)](https://travis-ci.org/sindresorhus/meow)
-
-> CLI app helper
-
-![](meow.gif)
-
-
-## Features
-
-- Parses arguments using [minimist](https://github.com/substack/minimist)
-- Converts flags to [camelCase](https://github.com/sindresorhus/camelcase)
-- Outputs version when `--version`
-- Outputs description and supplied help text when `--help`
-- Makes unhandled rejected promises [fail loudly](https://github.com/sindresorhus/loud-rejection) instead of the default silent fail
-- Sets the process title to the binary name defined in package.json
-
-
-## Install
-
-```
-$ npm install --save meow
-```
-
-
-## Usage
-
-```
-$ ./foo-app.js unicorns --rainbow-cake
-```
-
-```js
-#!/usr/bin/env node
-'use strict';
-const meow = require('meow');
-const foo = require('./');
-
-const cli = meow(`
-	Usage
-	  $ foo <input>
-
-	Options
-	  -r, --rainbow  Include a rainbow
-
-	Examples
-	  $ foo unicorns --rainbow
-	  🌈 unicorns 🌈
-`, {
-	alias: {
-		r: 'rainbow'
-	}
-});
-/*
-{
-	input: ['unicorns'],
-	flags: {rainbow: true},
-	...
-}
-*/
-
-foo(cli.input[0], cli.flags);
-```
-
-
-## API
-
-### meow(options, [minimistOptions])
-
-Returns an object with:
-
-- `input` *(array)* - Non-flag arguments
-- `flags` *(object)* - Flags converted to camelCase
-- `pkg` *(object)* - The `package.json` object
-- `help` *(object)* - The help text used with `--help`
-- `showHelp([code=0])` *(function)* - Show the help text and exit with `code`
-
-#### options
-
-Type: `object`, `array`, `string`
-
-Can either be a string/array that is the `help` or an options object.
-
-##### description
-
-Type: `string`, `boolean`
-Default: The package.json `"description"` property
-
-A description to show above the help text.
-
-Set it to `false` to disable it altogether.
-
-##### help
-
-Type: `string`, `boolean`
-
-The help text you want shown.
-
-The input is reindented and starting/ending newlines are trimmed which means you can use a [template literal](https://developer.mozilla.org/en/docs/Web/JavaScript/Reference/template_strings) without having to care about using the correct amount of indent.
-
-<del>If it's an array each item will be a line.</del>  
-*(Still supported, but you should use a template literal instead.)*
-
-The description will be shown above your help text automatically.
-
-Set it to `false` to disable it altogether.
-
-##### version
-
-Type: `string`, `boolean`  
-Default: The package.json `"version"` property
-
-Set a custom version output.
-
-Set it to `false` to disable it altogether.
-
-##### pkg
-
-Type: `string`, `object`  
-Default: Closest package.json upwards
-
-Relative path to package.json or as an object.
-
-##### argv
-
-Type: `array`  
-Default: `process.argv.slice(2)`
-
-Custom arguments object.
-
-#### minimistOptions
-
-Type: `object`  
-Default: `{}`
-
-Minimist [options](https://github.com/substack/minimist#var-argv--parseargsargs-opts).
-
-Keys passed to the minimist `default` option are [decamelized](https://github.com/sindresorhus/decamelize), so you can for example pass in `fooBar: 'baz'` and have it be the default for the `--foo-bar` flag.
-
-
-## Promises
-
-Meow will make unhandled rejected promises [fail loudly](https://github.com/sindresorhus/loud-rejection) instead of the default silent fail. Meaning you don't have to manually `.catch()` promises used in your CLI.
-
-
-## Tips
-
-See [`chalk`](https://github.com/chalk/chalk) if you want to colorize the terminal output.
-
-See [`get-stdin`](https://github.com/sindresorhus/get-stdin) if you want to accept input from stdin.
-
-See [`update-notifier`](https://github.com/yeoman/update-notifier) if you want update notifications.
-
-See [`configstore`](https://github.com/yeoman/configstore) if you need to persist some data.

-This is a database of all mime types.
-It consists of a single, public JSON file and does not include any logic,
-allowing it to remain as un-opinionated as possible with an API.
-It aggregates data from the following sources:
-
-- http://www.iana.org/assignments/media-types/media-types.xhtml
-- http://svn.apache.org/repos/asf/httpd/httpd/trunk/docs/conf/mime.types
-- http://hg.nginx.org/nginx/raw-file/default/conf/mime.types
-
-## Installation
-
-```bash
-npm install mime-db
-```
-
-### Database Download
-
-If you're crazy enough to use this in the browser, you can just grab the
-JSON file using [jsDelivr](https://www.jsdelivr.com/). It is recommended to
-replace `master` with [a release tag](https://github.com/jshttp/mime-db/tags)
-as the JSON format may change in the future.
-
-```
-https://cdn.jsdelivr.net/gh/jshttp/mime-db@master/db.json
-```
-
-## Usage
-
-```js
-var db = require('mime-db');
-
-// grab data on .js files
-var data = db['application/javascript'];
-```
-
-## Data Structure
-
-The JSON file is a map lookup for lowercased mime types.
-Each mime type has the following properties:
-
-- `.source` - where the mime type is defined.
-    If not set, it's probably a custom media type.
-    - `apache` - [Apache common media types](http://svn.apache.org/repos/asf/httpd/httpd/trunk/docs/conf/mime.types)
-    - `iana` - [IANA-defined media types](http://www.iana.org/assignments/media-types/media-types.xhtml)
-    - `nginx` - [nginx media types](http://hg.nginx.org/nginx/raw-file/default/conf/mime.types)
-- `.extensions[]` - known extensions associated with this mime type.
-- `.compressible` - whether a file of this type can be gzipped.
-- `.charset` - the default charset associated with this type, if any.
-
-If unknown, every property could be `undefined`.
-
-## Contributing
-
-To edit the database, only make PRs against `src/custom.json` or
-`src/custom-suffix.json`.
-
-The `src/custom.json` file is a JSON object with the MIME type as the keys
-and the values being an object with the following keys:
-
-- `compressible` - leave out if you don't know, otherwise `true`/`false` to
-  indicate whether the data represented by the type is typically compressible.
-- `extensions` - include an array of file extensions that are associated with
-  the type.
-- `notes` - human-readable notes about the type, typically what the type is.
-- `sources` - include an array of URLs of where the MIME type and the associated
-  extensions are sourced from. This needs to be a [primary source](https://en.wikipedia.org/wiki/Primary_source);
-  links to type aggregating sites and Wikipedia are _not acceptable_.
-
-To update the build, run `npm run build`.
-
-### Adding Custom Media Types
-
-The best way to get new media types included in this library is to register
-them with the IANA. The community registration procedure is outlined in
-[RFC 6838 section 5](http://tools.ietf.org/html/rfc6838#section-5). Types
-registered with the IANA are automatically pulled into this library.
-
-If that is not possible / feasible, they can be added directly here as a
-"custom" type. To do this, it is required to have a primary source that
-definitively lists the media type. If an extension is going to be listed as
-associateed with this media type, the source must definitively link the
-media type and extension as well.

-
-The ultimate javascript content-type utility.
-
-Similar to [the `mime@1.x` module](https://www.npmjs.com/package/mime), except:
-
-- __No fallbacks.__ Instead of naively returning the first available type,
-  `mime-types` simply returns `false`, so do
-  `var type = mime.lookup('unrecognized') || 'application/octet-stream'`.
-- No `new Mime()` business, so you could do `var lookup = require('mime-types').lookup`.
-- No `.define()` functionality
-- Bug fixes for `.lookup(path)`
-
-Otherwise, the API is compatible with `mime` 1.x.
-
-## Install
-
-This is a [Node.js](https://nodejs.org/en/) module available through the
-[npm registry](https://www.npmjs.com/). Installation is done using the
-[`npm install` command](https://docs.npmjs.com/getting-started/installing-npm-packages-locally):
-
-```sh
-$ npm install mime-types
-```
-
-## Adding Types
-
-All mime types are based on [mime-db](https://www.npmjs.com/package/mime-db),
-so open a PR there if you'd like to add mime types.
-
-## API
-
-```js
-var mime = require('mime-types')
-```
-
-All functions return `false` if input is invalid or not found.
-
-### mime.lookup(path)
-
-Lookup the content-type associated with a file.

-```js
-mime.lookup('json')             // 'application/json'

-
-### mime.contentType(type)
-
-Create a full content-type header given a content-type or extension.
-When given an extension, `mime.lookup` is used to get the matching
-content-type, otherwise the given content-type is used. Then if the
-content-type does not already have a `charset` parameter, `mime.charset`
-is used to get the default charset and add to the returned content-type.
-
-```js
-mime.contentType('markdown')  // 'text/x-markdown; charset=utf-8'
-mime.contentType('file.json') // 'application/json; charset=utf-8'
-mime.contentType('text/html') // 'text/html; charset=utf-8'
-mime.contentType('text/html; charset=iso-8859-1') // 'text/html; charset=iso-8859-1'
-
-// from a full path
-mime.contentType(path.extname('/path/to/file.json')) // 'application/json; charset=utf-8'
-```
-
-### mime.extension(type)
-
-Get the default extension for a content-type.
-
-```js
-mime.extension('application/octet-stream') // 'bin'
-```
-
-### mime.charset(type)
-
-Lookup the implied default charset of a content-type.
-
-```js
-mime.charset('text/markdown') // 'UTF-8'
-```
-
-### var type = mime.types[extension]
-
-A map of content-types by extension.
-
-### [extensions...] = mime.extensions[type]
-
-A map of extensions by content-type.

-# minimist
-
-parse argument options
-
-This module is the guts of optimist's argument parser without all the
-fanciful decoration.
-
-[![browser support](https://ci.testling.com/substack/minimist.png)](http://ci.testling.com/substack/minimist)
-
-[![build status](https://secure.travis-ci.org/substack/minimist.png)](http://travis-ci.org/substack/minimist)
-
-# example
-
-``` js
-var argv = require('minimist')(process.argv.slice(2));
-console.dir(argv);
-```
-
-```
-$ node example/parse.js -a beep -b boop
-{ _: [], a: 'beep', b: 'boop' }
-```
-
-```
-$ node example/parse.js -x 3 -y 4 -n5 -abc --beep=boop foo bar baz
-{ _: [ 'foo', 'bar', 'baz' ],
-  x: 3,
-  y: 4,
-  n: 5,
-  a: true,
-  b: true,
-  c: true,
-  beep: 'boop' }
-```
-
-# methods
-
-``` js
-var parseArgs = require('minimist')
-```
-
-## var argv = parseArgs(args, opts={})
-
-Return an argument object `argv` populated with the array arguments from `args`.
-
-`argv._` contains all the arguments that didn't have an option associated with
-them.
-
-Numeric-looking arguments will be returned as numbers unless `opts.string` or
-`opts.boolean` is set for that argument name.
-
-Any arguments after `'--'` will not be parsed and will end up in `argv._`.
-
-options can be:
-
-* `opts.string` - a string or array of strings argument names to always treat as
-strings
-* `opts.boolean` - a boolean, string or array of strings to always treat as
-booleans. if `true` will treat all double hyphenated arguments without equal signs
-as boolean (e.g. affects `--foo`, not `-f` or `--foo=bar`)
-* `opts.alias` - an object mapping string names to strings or arrays of string
-argument names to use as aliases
-* `opts.default` - an object mapping string argument names to default values
-* `opts.stopEarly` - when true, populate `argv._` with everything after the
-first non-option
-* `opts['--']` - when true, populate `argv._` with everything before the `--`
-and `argv['--']` with everything after the `--`. Here's an example:
-* `opts.unknown` - a function which is invoked with a command line parameter not
-defined in the `opts` configuration object. If the function returns `false`, the
-unknown option is not added to `argv`.
-
-```
-> require('./')('one two three -- four five --six'.split(' '), { '--': true })
-{ _: [ 'one', 'two', 'three' ],
-  '--': [ 'four', 'five', '--six' ] }
-```
-
-Note that with `opts['--']` set, parsing for arguments still stops after the
-`--`.
-

-With [npm](https://npmjs.org) do:

-npm install minimist

-
-parse argument options
-
-This module is the guts of optimist's argument parser without all the
-fanciful decoration.
-
-[![browser support](https://ci.testling.com/substack/minimist.png)](http://ci.testling.com/substack/minimist)
-
-[![build status](https://secure.travis-ci.org/substack/minimist.png)](http://travis-ci.org/substack/minimist)
-
-# example
-
-``` js
-var argv = require('minimist')(process.argv.slice(2));
-console.dir(argv);
-```
-
-```
-$ node example/parse.js -a beep -b boop
-{ _: [], a: 'beep', b: 'boop' }
-```
-
-```
-$ node example/parse.js -x 3 -y 4 -n5 -abc --beep=boop foo bar baz
-{ _: [ 'foo', 'bar', 'baz' ],
-  x: 3,
-  y: 4,
-  n: 5,
-  a: true,
-  b: true,

-  beep: 'boop' }
-```
-
-# methods
-
-``` js
-var parseArgs = require('minimist')
-```
-
-## var argv = parseArgs(args, opts={})
-
-Return an argument object `argv` populated with the array arguments from `args`.
-
-`argv._` contains all the arguments that didn't have an option associated with
-them.
-
-Numeric-looking arguments will be returned as numbers unless `opts.string` or
-`opts.boolean` is set for that argument name.
-
-Any arguments after `'--'` will not be parsed and will end up in `argv._`.
-
-options can be:
-
-* `opts.string` - a string or array of strings argument names to always treat as
-strings
-* `opts.boolean` - a string or array of strings to always treat as booleans
-* `opts.alias` - an object mapping string names to strings or arrays of string
-argument names to use as aliases
-* `opts.default` - an object mapping string argument names to default values

-# mkdirp
-
-Like `mkdir -p`, but in node.js!
-
-[![build status](https://secure.travis-ci.org/substack/node-mkdirp.png)](http://travis-ci.org/substack/node-mkdirp)
-
-# example
-
-## pow.js
-
-```js
-var mkdirp = require('mkdirp');
-    
-mkdirp('/tmp/foo/bar/baz', function (err) {
-    if (err) console.error(err)
-    else console.log('pow!')
-});
-```
-
-Output
-
-```
-pow!
-```
-
-And now /tmp/foo/bar/baz exists, huzzah!
-
-# methods
-
-```js
-var mkdirp = require('mkdirp');
-```
-
-## mkdirp(dir, opts, cb)
-
-Create a new directory and any necessary subdirectories at `dir` with octal
-permission string `opts.mode`. If `opts` is a non-object, it will be treated as
-the `opts.mode`.
-
-If `opts.mode` isn't specified, it defaults to `0777 & (~process.umask())`.
-
-`cb(err, made)` fires with the error or the first directory `made`
-that had to be created, if any.
-
-You can optionally pass in an alternate `fs` implementation by passing in
-`opts.fs`. Your implementation should have `opts.fs.mkdir(path, mode, cb)` and
-`opts.fs.stat(path, cb)`.
-
-## mkdirp.sync(dir, opts)
-
-Synchronously create a new directory and any necessary subdirectories at `dir`
-with octal permission string `opts.mode`. If `opts` is a non-object, it will be
-treated as the `opts.mode`.
-
-If `opts.mode` isn't specified, it defaults to `0777 & (~process.umask())`.
-
-Returns the first directory that had to be created, if any.
-
-You can optionally pass in an alternate `fs` implementation by passing in
-`opts.fs`. Your implementation should have `opts.fs.mkdirSync(path, mode)` and
-`opts.fs.statSync(path)`.
-
-# usage
-
-This package also ships with a `mkdirp` command.
-
-```
-usage: mkdirp [DIR1,DIR2..] {OPTIONS}
-
-  Create each supplied directory including any necessary parent directories that
-  don't yet exist.
-  
-  If the directory already exists, do nothing.
-
-OPTIONS are:
-
-  -m, --mode   If a directory needs to be created, set the mode as an octal
-               permission string.
-
-```
-
-# install
-
-With [npm](http://npmjs.org) do:
-
-```
-npm install mkdirp
-```
-
-to get the library, or
-
-```
-npm install -g mkdirp
-```
-
-to get the command.

-node-gyp
-=========
-## Node.js native addon build tool
-
-`node-gyp` is a cross-platform command-line tool written in Node.js for compiling
-native addon modules for Node.js.  It bundles the [gyp](https://gyp.gsrc.io)
-project used by the Chromium team and takes away the pain of dealing with the
-various differences in build platforms. It is the replacement to the `node-waf`
-program which is removed for node `v0.8`. If you have a native addon for node that
-still has a `wscript` file, then you should definitely add a `binding.gyp` file
-to support the latest versions of node.
-
-Multiple target versions of node are supported (i.e. `0.8`, ..., `4`, `5`, `6`,
-etc.), regardless of what version of node is actually installed on your system
-(`node-gyp` downloads the necessary development files or headers for the target version).
-
-## Features
-
- * Easy to use, consistent interface
- * Same commands to build your module on every platform
- * Supports multiple target versions of Node
-
-
-Installation
-------------
-
-You can install with `npm`:
-
-``` bash
-$ npm install -g node-gyp
-```
-
-You will also need to install:
-
-### On Unix
-
-   * `python` (`v2.7` recommended, `v3.x.x` is __*not*__ supported)
-   * `make`
-   * A proper C/C++ compiler toolchain, like [GCC](https://gcc.gnu.org)
-
-### On macOS
-
-   * `python` (`v2.7` recommended, `v3.x.x` is __*not*__ supported) (already installed on macOS)
-   * [Xcode](https://developer.apple.com/xcode/download/)
-     * You also need to install the `Command Line Tools` via Xcode. You can find this under the menu `Xcode -> Preferences -> Locations` (or by running `xcode-select --install` in your Terminal)
-       * This step will install `gcc` and the related toolchain containing `make`
-
-### On Windows
-
-#### Option 1
-
-Install all the required tools and configurations using Microsoft's [windows-build-tools](https://github.com/felixrieseberg/windows-build-tools) using `npm install --global --production windows-build-tools` from an elevated PowerShell or CMD.exe (run as Administrator).
-
-#### Option 2
-
-Install tools and configuration manually:
-   * Install Visual C++ Build Environment: [Visual Studio Build Tools](https://visualstudio.microsoft.com/thank-you-downloading-visual-studio/?sku=BuildTools)
-   (using "Visual C++ build tools" workload) or [Visual Studio 2017 Community](https://visualstudio.microsoft.com/pl/thank-you-downloading-visual-studio/?sku=Community)
-   (using the "Desktop development with C++" workload)
-   * Install [Python 2.7](https://www.python.org/downloads/) (`v3.x.x` is not supported), and run `npm config set python python2.7` (or see below for further instructions on specifying the proper Python version and path.)
-   * Launch cmd, `npm config set msvs_version 2017`
-
-   If the above steps didn't work for you, please visit [Microsoft's Node.js Guidelines for Windows](https://github.com/Microsoft/nodejs-guidelines/blob/master/windows-environment.md#compiling-native-addon-modules) for additional tips.
-
-If you have multiple Python versions installed, you can identify which Python
-version `node-gyp` uses by setting the '--python' variable:
-
-``` bash
-$ node-gyp --python /path/to/python2.7
-```
-
-If `node-gyp` is called by way of `npm` *and* you have multiple versions of
-Python installed, then you can set `npm`'s 'python' config key to the appropriate
-value:
-
-``` bash
-$ npm config set python /path/to/executable/python2.7
-```
-
-How to Use
-----------
-
-To compile your native addon, first go to its root directory:
-
-``` bash
-$ cd my_node_addon
-```
-
-The next step is to generate the appropriate project build files for the current
-platform. Use `configure` for that:
-
-``` bash
-$ node-gyp configure
-```
-
-Auto-detection fails for Visual C++ Build Tools 2015, so `--msvs_version=2015`
-needs to be added (not needed when run by npm as configured above):
-``` bash
-$ node-gyp configure --msvs_version=2015
-```
-
-__Note__: The `configure` step looks for the `binding.gyp` file in the current
-directory to process. See below for instructions on creating the `binding.gyp` file.
-
-Now you will have either a `Makefile` (on Unix platforms) or a `vcxproj` file
-(on Windows) in the `build/` directory. Next invoke the `build` command:
-
-``` bash
-$ node-gyp build
-```
-
-Now you have your compiled `.node` bindings file! The compiled bindings end up
-in `build/Debug/` or `build/Release/`, depending on the build mode. At this point
-you can require the `.node` file with Node and run your tests!
-
-__Note:__ To create a _Debug_ build of the bindings file, pass the `--debug` (or
-`-d`) switch when running either the `configure`, `build` or `rebuild` command.
-
-
-The "binding.gyp" file
-----------------------
-
-Previously when node had `node-waf` you had to write a `wscript` file. The
-replacement for that is the `binding.gyp` file, which describes the configuration
-to build your module in a JSON-like format. This file gets placed in the root of
-your package, alongside the `package.json` file.
-
-A barebones `gyp` file appropriate for building a node addon looks like:
-
-``` python
-{
-  "targets": [
-    {
-      "target_name": "binding",
-      "sources": [ "src/binding.cc" ]
-    }
-  ]
-}
-```
-
-Some additional resources for addons and writing `gyp` files:
-
- * ["Going Native" a nodeschool.io tutorial](http://nodeschool.io/#goingnative)
- * ["Hello World" node addon example](https://github.com/nodejs/node/tree/master/test/addons/hello-world)
- * [gyp user documentation](https://gyp.gsrc.io/docs/UserDocumentation.md)
- * [gyp input format reference](https://gyp.gsrc.io/docs/InputFormatReference.md)
- * [*"binding.gyp" files out in the wild* wiki page](https://github.com/nodejs/node-gyp/wiki/%22binding.gyp%22-files-out-in-the-wild)

-Commands
---------
-
-`node-gyp` responds to the following commands:
-
-| **Command**   | **Description**
-|:--------------|:---------------------------------------------------------------
-| `help`        | Shows the help dialog
-| `build`       | Invokes `make`/`msbuild.exe` and builds the native addon
-| `clean`       | Removes the `build` directory if it exists
-| `configure`   | Generates project build files for the current platform
-| `rebuild`     | Runs `clean`, `configure` and `build` all in a row
-| `install`     | Installs node header files for the given version
-| `list`        | Lists the currently installed node header versions
-| `remove`      | Removes the node header files for the given version
-
-
-Command Options

-
-Configuration
---------
-
-__`node-gyp` responds to environment variables or `npm` configuration__
-1. Environment variables take the form `npm_config_OPTION_NAME` for any of the 
- options listed above (dashes in option names should be replaced by underscores).
- These work also when `node-gyp` is invoked directly:  
- `$ export npm_config_devdir=/tmp/.gyp`  
- or on Windows  
- `> set npm_config_devdir=c:\temp\.gyp`  
-2. As `npm` configuration, variables take the form `OPTION_NAME`.
- This way only works when `node-gyp` is executed by `npm`:  
- `$ npm config set [--global] devdir /tmp/.gyp`  
- `$ npm i buffertools`

-This script is intended for use as a GYP_GENERATOR. It takes as input (by way of
-the generator flag config_path) the path of a json file that dictates the files
-and targets to search for. The following keys are supported:
-files: list of paths (relative) of the files to search for.
-test_targets: unqualified target names to search for. Any target in this list
-that depends upon a file in |files| is output regardless of the type of target
-or chain of dependencies.
-additional_compile_targets: Unqualified targets to search for in addition to
-test_targets. Targets in the combined list that depend upon a file in |files|
-are not necessarily output. For example, if the target is of type none then the
-target is not output (but one of the descendants of the target will be).
-
-The following is output:
-error: only supplied if there is an error.
-compile_targets: minimal set of targets that directly or indirectly (for
-  targets of type none) depend on the files in |files| and is one of the
-  supplied targets or a target that one of the supplied targets depends on.
-  The expectation is this set of targets is passed into a build step. This list
-  always contains the output of test_targets as well.
-test_targets: set of targets from the supplied |test_targets| that either
-  directly or indirectly depend upon a file in |files|. This list if useful
-  if additional processing needs to be done for certain targets after the
-  build, such as running tests.
-status: outputs one of three values: none of the supplied files were found,
-  one of the include files changed so that it should be assumed everything
-  changed (in this case test_targets and compile_targets are not output) or at
-  least one file was found.
-invalid_targets: list of supplied targets that were not found.
-
-Example:
-Consider a graph like the following:
-  A     D
- / \
-B   C
-A depends upon both B and C, A is of type none and B and C are executables.
-D is an executable, has no dependencies and nothing depends on it.
-If |additional_compile_targets| = ["A"], |test_targets| = ["B", "C"] and
-files = ["b.cc", "d.cc"] (B depends upon b.cc and D depends upon d.cc), then
-the following is output:
-|compile_targets| = ["B"] B must built as it depends upon the changed file b.cc
-and the supplied target A depends upon it. A is not output as a build_target
-as it is of type none with no rules and actions.
-|test_targets| = ["B"] B directly depends upon the change file b.cc.
-
-Even though the file d.cc, which D depends upon, has changed D is not output
-as it was not supplied by way of |additional_compile_targets| or |test_targets|.
-
-If the generator flag analyzer_output_path is specified, output is written
-there. Otherwise output is written to stdout.
-
-In Gyp the "all" target is shorthand for the root targets in the files passed
-to gyp. For example, if file "a.gyp" contains targets "a1" and
-"a2", and file "b.gyp" contains targets "b1" and "b2" and "a2" has a dependency
-on "b2" and gyp is supplied "a.gyp" then "all" consists of "a1" and "a2".
-Notice that "b1" and "b2" are not in the "all" target as "b.gyp" was not
-directly supplied to gyp. OTOH if both "a.gyp" and "b.gyp" are supplied to gyp
-then the "all" target includes "b1" and "b2".

-"""cmake output module
-
-This module is under development and should be considered experimental.
-
-This module produces cmake (2.8.8+) input as its output. One CMakeLists.txt is
-created for each configuration.
-
-This module's original purpose was to support editing in IDEs like KDevelop
-which use CMake for project management. It is also possible to use CMake to
-generate projects for other IDEs such as eclipse cdt and code::blocks. QtCreator
-will convert the CMakeLists.txt to a code::blocks cbp for the editor to read,
-but build using CMake. As a result QtCreator editor is unaware of compiler
-defines. The generated CMakeLists.txt can also be used to build on Linux. There
-is currently no support for building on platforms other than Linux.
-
-The generated CMakeLists.txt should properly compile all projects. However,
-there is a mismatch between gyp and cmake with regard to linking. All attempts
-are made to work around this, but CMake sometimes sees -Wl,--start-group as a
-library and incorrectly repeats it. As a result the output of this generator
-should not be relied on for building.
-
-When using with kdevelop, use version 4.4+. Previous versions of kdevelop will
-not be able to find the header file directories described in the generated
-CMakeLists.txt file.

-This backend DOES NOT generate Eclipse CDT projects. Instead, it generates XML

-list of include paths and symbols (i.e. defines).
-
-Because a full .cproject definition is not created by this generator, it's not
-possible to properly define the include dirs and symbols for each file
-individually.  Instead, one set of includes/symbols is generated for the entire
-project.  This works fairly well (and is a vast improvement in general), but may
-still result in a few indexer issues here and there.

-"""gypd output module
-
-This module produces gyp input as its output.  Output files are given the
-.gypd extension to avoid overwriting the .gyp files that they are generated
-from.  Internal references to .gyp files (such as those found in
-"dependencies" sections) are not adjusted to point to .gypd files instead;
-unlike other paths, which are relative to the .gyp or .gypd file, such paths
-are relative to the directory from which gyp was run to create the .gypd file.
-
-This generator module is intended to be a sample and a debugging aid, hence
-the "d" for "debug" in .gypd.  It is useful to inspect the results of the
-various merges, expansions, and conditional evaluations performed by gyp
-and to see a representation of what would be fed to a generator module.
-
-It's not advisable to rename .gypd files produced by this module to .gyp,
-because they will have all merges, expansions, and evaluations already
-performed and the relevant constructs not present in the output; paths to
-dependencies may be wrong; and various sections that do not belong in .gyp
-files such as such as "included_files" and "*_excluded" will be present.
-Output will also be stripped of comments.  This is not intended to be a
-general-purpose gyp pretty-printer; for that, you probably just want to
-run "pprint.pprint(eval(open('source.gyp').read()))", which will still strip
-comments but won't do all of the other things done to this module's output.
-
-The specific formatting of the output generated by this module is subject
-to change.

-"""Xcode project file generator.
-
-This module is both an Xcode project file generator and a documentation of the
-Xcode project file format.  Knowledge of the project file format was gained
-based on extensive experience with Xcode, and by making changes to projects in
-Xcode.app and observing the resultant changes in the associated project files.
-
-XCODE PROJECT FILES
-
-The generator targets the file format as written by Xcode 3.2 (specifically,
-3.2.6), but past experience has taught that the format has not changed
-significantly in the past several years, and future versions of Xcode are able
-to read older project files.
-
-Xcode project files are "bundled": the project "file" from an end-user's
-perspective is actually a directory with an ".xcodeproj" extension.  The
-project file from this module's perspective is actually a file inside this
-directory, always named "project.pbxproj".  This file contains a complete
-description of the project and is all that is needed to use the xcodeproj.
-Other files contained in the xcodeproj directory are simply used to store
-per-user settings, such as the state of various UI elements in the Xcode
-application.
-
-The project.pbxproj file is a property list, stored in a format almost
-identical to the NeXTstep property list format.  The file is able to carry
-Unicode data, and is encoded in UTF-8.  The root element in the property list
-is a dictionary that contains several properties of minimal interest, and two
-properties of immense interest.  The most important property is a dictionary
-named "objects".  The entire structure of the project is represented by the
-children of this property.  The objects dictionary is keyed by unique 96-bit
-values represented by 24 uppercase hexadecimal characters.  Each value in the
-objects dictionary is itself a dictionary, describing an individual object.
-
-Each object in the dictionary is a member of a class, which is identified by
-the "isa" property of each object.  A variety of classes are represented in a
-project file.  Objects can refer to other objects by ID, using the 24-character
-hexadecimal object key.  A project's objects form a tree, with a root object
-of class PBXProject at the root.  As an example, the PBXProject object serves
-as parent to an XCConfigurationList object defining the build configurations
-used in the project, a PBXGroup object serving as a container for all files
-referenced in the project, and a list of target objects, each of which defines
-a target in the project.  There are several different types of target object,
-such as PBXNativeTarget and PBXAggregateTarget.  In this module, this
-relationship is expressed by having each target type derive from an abstract
-base named XCTarget.
-
-The project.pbxproj file's root dictionary also contains a property, sibling to
-the "objects" dictionary, named "rootObject".  The value of rootObject is a
-24-character object key referring to the root PBXProject object in the
-objects dictionary.
-
-In Xcode, every file used as input to a target or produced as a final product
-of a target must appear somewhere in the hierarchy rooted at the PBXGroup
-object referenced by the PBXProject's mainGroup property.  A PBXGroup is
-generally represented as a folder in the Xcode application.  PBXGroups can
-contain other PBXGroups as well as PBXFileReferences, which are pointers to
-actual files.
-
-Each XCTarget contains a list of build phases, represented in this module by
-the abstract base XCBuildPhase.  Examples of concrete XCBuildPhase derivations
-are PBXSourcesBuildPhase and PBXFrameworksBuildPhase, which correspond to the
-"Compile Sources" and "Link Binary With Libraries" phases displayed in the
-Xcode application.  Files used as input to these phases (for example, source
-files in the former case and libraries and frameworks in the latter) are
-represented by PBXBuildFile objects, referenced by elements of "files" lists
-in XCTarget objects.  Each PBXBuildFile object refers to a PBXBuildFile
-object as a "weak" reference: it does not "own" the PBXBuildFile, which is
-owned by the root object's mainGroup or a descendant group.  In most cases, the
-layer of indirection between an XCBuildPhase and a PBXFileReference via a
-PBXBuildFile appears extraneous, but there's actually one reason for this:
-file-specific compiler flags are added to the PBXBuildFile object so as to
-allow a single file to be a member of multiple targets while having distinct
-compiler flags for each.  These flags can be modified in the Xcode applciation
-in the "Build" tab of a File Info window.
-
-When a project is open in the Xcode application, Xcode will rewrite it.  As
-such, this module is careful to adhere to the formatting used by Xcode, to
-avoid insignificant changes appearing in the file when it is used in the
-Xcode application.  This will keep version control repositories happy, and
-makes it possible to compare a project file used in Xcode to one generated by
-this module to determine if any significant changes were made in the
-application.
-
-Xcode has its own way of assigning 24-character identifiers to each object,
-which is not duplicated here.  Because the identifier only is only generated
-once, when an object is created, and is then left unchanged, there is no need
-to attempt to duplicate Xcode's behavior in this area.  The generator is free
-to select any identifier, even at random, to refer to the objects it creates,
-and Xcode will retain those identifiers and use them when subsequently
-rewriting the project file.  However, the generator would choose new random
-identifiers each time the project files are generated, leading to difficulties
-comparing "used" project files to "pristine" ones produced by this module,
-and causing the appearance of changes as every object identifier is changed
-when updated projects are checked in to a version control repository.  To
-mitigate this problem, this module chooses identifiers in a more deterministic
-way, by hashing a description of each object as well as its parent and ancestor
-objects.  This strategy should result in minimal "shift" in IDs as successive
-generations of project files are produced.
-
-THIS MODULE
-
-This module introduces several classes, all derived from the XCObject class.
-Nearly all of the "brains" are built into the XCObject class, which understands
-how to create and modify objects, maintain the proper tree structure, compute
-identifiers, and print objects.  For the most part, classes derived from
-XCObject need only provide a _schema class object, a dictionary that
-expresses what properties objects of the class may contain.
-
-Given this structure, it's possible to build a minimal project file by creating
-objects of the appropriate types and making the proper connections:
-
-  config_list = XCConfigurationList()
-  group = PBXGroup()
-  project = PBXProject({'buildConfigurationList': config_list,
-                        'mainGroup': group})
-
-With the project object set up, it can be added to an XCProjectFile object.
-XCProjectFile is a pseudo-class in the sense that it is a concrete XCObject
-subclass that does not actually correspond to a class type found in a project
-file.  Rather, it is used to represent the project file's root dictionary.
-Printing an XCProjectFile will print the entire project file, including the
-full "objects" dictionary.
-
-  project_file = XCProjectFile({'rootObject': project})
-  project_file.ComputeIDs()
-  project_file.Print()
-
-Xcode project files are always encoded in UTF-8.  This module will accept
-strings of either the str class or the unicode class.  Strings of class str
-are assumed to already be encoded in UTF-8.  Obviously, if you're just using
-ASCII, you won't encounter difficulties because ASCII is a UTF-8 subset.
-Strings of class unicode are handled properly and encoded in UTF-8 when
-a project file is output.

-
-  Class variables:
-    _schema: A dictionary defining the properties of this class.  The keys to
-             _schema are string property keys as used in project files.  Values
-             are a list of four or five elements:
-             [ is_list, property_type, is_strong, is_required, default ]
-             is_list: True if the property described is a list, as opposed
-                      to a single element.
-             property_type: The type to use as the value of the property,
-                            or if is_list is True, the type to use for each
-                            element of the value's list.  property_type must
-                            be an XCObject subclass, or one of the built-in
-                            types str, int, or dict.
-             is_strong: If property_type is an XCObject subclass, is_strong
-                        is True to assert that this class "owns," or serves
-                        as parent, to the property value (or, if is_list is
-                        True, values).  is_strong must be False if
-                        property_type is not an XCObject subclass.
-             is_required: True if the property is required for the class.
-                          Note that is_required being True does not preclude
-                          an empty string ("", in the case of property_type
-                          str) or list ([], in the case of is_list True) from
-                          being set for the property.
-             default: Optional.  If is_requried is True, default may be set
-                      to provide a default value for objects that do not supply
-                      their own value.  If is_required is True and default
-                      is not provided, users of the class must supply their own
-                      value for the property.
-             Note that although the values of the array are expressed in
-             boolean terms, subclasses provide values as integers to conserve
-             horizontal space.
-    _should_print_single_line: False in XCObject.  Subclasses whose objects
-                               should be written to the project file in the
-                               alternate single-line format, such as
-                               PBXFileReference and PBXBuildFile, should
-                               set this to True.
-    _encode_transforms: Used by _EncodeString to encode unprintable characters.
-                        The index into this list is the ordinal of the
-                        character to transform; each value is a string
-                        used to represent the character in the output.  XCObject
-                        provides an _encode_transforms list suitable for most
-                        XCObject subclasses.
-    _alternate_encode_transforms: Provided for subclasses that wish to use
-                                  the alternate encoding rules.  Xcode seems
-                                  to use these rules when printing objects in
-                                  single-line format.  Subclasses that desire
-                                  this behavior should set _encode_transforms
-                                  to _alternate_encode_transforms.
-    _hashables: A list of XCObject subclasses that can be hashed by ComputeIDs
-                to construct this object's ID.  Most classes that need custom
-                hashing behavior should do it by overriding Hashables,
-                but in some cases an object's parent may wish to push a
-                hashable value into its child, and it can do so by appending
-                to _hashables.
-  Attributes:
-    id: The object's identifier, a 24-character uppercase hexadecimal string.
-        Usually, objects being created should not set id until the entire
-        project file structure is built.  At that point, UpdateIDs() should
-        be called on the root object to assign deterministic values for id to
-        each object in the tree.
-    parent: The object's parent.  This is set by a parent XCObject when a child
-            object is added to it.
-    _properties: The object's property dictionary.  An object's properties are
-                 described by its class' _schema variable.

-
-    XCHierarchicalElements are special.  Generally, their hashes shouldn't
-    change if the paths don't change.  The normal XCObject implementation of
-    Hashables adds a hashable for each object, which means that if
-    the hierarchical structure changes (possibly due to changes caused when
-    TakeOverOnlyChild runs and encounters slight changes in the hierarchy),
-    the hashes will change.  For example, if a project file initially contains
-    a/b/f1 and a/b becomes collapsed into a/b, f1 will have a single parent
-    a/b.  If someone later adds a/f2 to the project file, a/b can no longer be
-    collapsed, and f1 winds up with parent b and grandparent a.  That would
-    be sufficient to change f1's hash.
-
-    To counteract this problem, hashables for all XCHierarchicalElements except
-    for the main group (which has neither a name nor a path) are taken to be
-    just the set of path components.  Because hashables are inherited from
-    parents, this provides assurance that a/b/f1 has the same set of hashables
-    whether its parent is b or a/b.
-
-    The main group is a special case.  As it is permitted to have no name or
-    path, it is permitted to use the standard XCObject hash mechanism.  This
-    is not considered a problem because there can be only one main group.

-
-  They key/value pair are used to resolve vsprops name.
-
-  For example, if I want to diff the base.vcproj project:
-
-  pretty_vcproj.py z:\dev\src-chrome\src\base\build\base.vcproj "$(SolutionDir)=z:\dev\src-chrome\src\chrome\\" "$(CHROMIUM_BUILD)=" "$(CHROME_BUILD_TYPE)=" > orignal.txt

-
-  And you can use your favorite diff tool to see the changes.
-
-  Note: In the case of base.vcproj, the original vcproj is one level up the generated one.
-        I suggest you do a search and replace for '"..\' and replace it with '"' in original.txt
-        before you perform the diff.

-Add the following to your ~/.emacs (replace ... with the path to your gyp
-checkout).
-
-(setq load-path (cons ".../tools/emacs" load-path))
-(require 'gyp)
-
-Restart emacs (or eval-region the added lines) and you should be all set.

-
-This is a glob implementation in JavaScript.  It uses the `minimatch`
-library to do its matching.
-
-![](logo/glob.png)
-
-## Usage
-
-Install with npm
-
-```
-npm i glob
-```
-
-```javascript
-var glob = require("glob")
-
-// options is optional
-glob("**/*.js", options, function (er, files) {
-  // files is an array of filenames.
-  // If the `nonull` option is set, and nothing
-  // was found, then files is ["**/*.js"]
-  // er is an error object or null.
-})
-```
-
-## Glob Primer
-
-"Globs" are the patterns you type when you do stuff like `ls *.js` on
-the command line, or put `build/*` in a `.gitignore` file.
-
-Before parsing the path part patterns, braced sections are expanded
-into a set.  Braced sections start with `{` and end with `}`, with any
-number of comma-delimited sections within.  Braced sections may contain
-slash characters, so `a{/b/c,bcd}` would expand into `a/b/c` and `abcd`.
-
-The following characters have special magic meaning when used in a
-path portion:
-
-* `*` Matches 0 or more characters in a single path portion
-* `?` Matches 1 character
-* `[...]` Matches a range of characters, similar to a RegExp range.
-  If the first character of the range is `!` or `^` then it matches
-  any character not in the range.
-* `!(pattern|pattern|pattern)` Matches anything that does not match
-  any of the patterns provided.
-* `?(pattern|pattern|pattern)` Matches zero or one occurrence of the
-  patterns provided.
-* `+(pattern|pattern|pattern)` Matches one or more occurrences of the
-  patterns provided.
-* `*(a|b|c)` Matches zero or more occurrences of the patterns provided
-* `@(pattern|pat*|pat?erN)` Matches exactly one of the patterns
-  provided
-* `**` If a "globstar" is alone in a path portion, then it matches
-  zero or more directories and subdirectories searching for matches.
-  It does not crawl symlinked directories.
-
-### Dots
-
-If a file or directory path portion has a `.` as the first character,
-then it will not match any glob pattern unless that pattern's
-corresponding path part also has a `.` as its first character.
-
-For example, the pattern `a/.*/c` would match the file at `a/.b/c`.
-However the pattern `a/*/c` would not, because `*` does not start with
-a dot character.
-
-You can make glob treat dots as normal characters by setting
-`dot:true` in the options.
-
-### Basename Matching
-
-If you set `matchBase:true` in the options, and the pattern has no
-slashes in it, then it will seek for any file anywhere in the tree
-with a matching basename.  For example, `*.js` would match
-`test/simple/basic.js`.
-
-### Empty Sets
-
-If no matching files are found, then an empty array is returned.  This
-differs from the shell, where the pattern itself is returned.  For
-example:
-
-    $ echo a*s*d*f
-    a*s*d*f
-
-To get the bash-style behavior, set the `nonull:true` in the options.
-
-### See Also:
-
-* `man sh`
-* `man bash` (Search for "Pattern Matching")
-* `man 3 fnmatch`
-* `man 5 gitignore`
-* [minimatch documentation](https://github.com/isaacs/minimatch)
-
-## glob.hasMagic(pattern, [options])
-
-Returns `true` if there are any special characters in the pattern, and
-`false` otherwise.
-
-Note that the options affect the results.  If `noext:true` is set in
-the options object, then `+(a|b)` will not be considered a magic
-pattern.  If the pattern has a brace expansion, like `a/{b/c,x/y}`
-then that is considered magical, unless `nobrace:true` is set in the
-options.
-
-## glob(pattern, [options], cb)
-
-* `pattern` `{String}` Pattern to be matched
-* `options` `{Object}`
-* `cb` `{Function}`
-  * `err` `{Error | null}`
-  * `matches` `{Array<String>}` filenames found matching the pattern
-
-Perform an asynchronous glob search.
-
-## glob.sync(pattern, [options])
-
-* `pattern` `{String}` Pattern to be matched
-* `options` `{Object}`
-* return: `{Array<String>}` filenames found matching the pattern
-
-Perform a synchronous glob search.
-
-## Class: glob.Glob
-
-Create a Glob object by instantiating the `glob.Glob` class.
-
-```javascript
-var Glob = require("glob").Glob
-var mg = new Glob(pattern, options, cb)

-
-It's an EventEmitter, and starts walking the filesystem to find matches
-immediately.
-
-### new glob.Glob(pattern, [options], [cb])
-
-* `pattern` `{String}` pattern to search for
-* `options` `{Object}`
-* `cb` `{Function}` Called when an error occurs, or matches are found
-  * `err` `{Error | null}`
-  * `matches` `{Array<String>}` filenames found matching the pattern
-
-Note that if the `sync` flag is set in the options, then matches will
-be immediately available on the `g.found` member.
-
-### Properties
-
-* `minimatch` The minimatch object that the glob uses.
-* `options` The options object passed in.
-* `aborted` Boolean which is set to true when calling `abort()`.  There
-  is no way at this time to continue a glob search after aborting, but
-  you can re-use the statCache to avoid having to duplicate syscalls.
-* `cache` Convenience object.  Each field has the following possible
-  values:
-  * `false` - Path does not exist
-  * `true` - Path exists
-  * `'FILE'` - Path exists, and is not a directory
-  * `'DIR'` - Path exists, and is a directory
-  * `[file, entries, ...]` - Path exists, is a directory, and the
-    array value is the results of `fs.readdir`
-* `statCache` Cache of `fs.stat` results, to prevent statting the same
-  path multiple times.
-* `symlinks` A record of which paths are symbolic links, which is
-  relevant in resolving `**` patterns.
-* `realpathCache` An optional object which is passed to `fs.realpath`
-  to minimize unnecessary syscalls.  It is stored on the instantiated
-  Glob object, and may be re-used.
-
-### Events
-
-* `end` When the matching is finished, this is emitted with all the
-  matches found.  If the `nonull` option is set, and no match was found,
-  then the `matches` list contains the original pattern.  The matches
-  are sorted, unless the `nosort` flag is set.
-* `match` Every time a match is found, this is emitted with the specific
-  thing that matched. It is not deduplicated or resolved to a realpath.
-* `error` Emitted when an unexpected error is encountered, or whenever
-  any fs error occurs if `options.strict` is set.
-* `abort` When `abort()` is called, this event is raised.
-
-### Methods
-
-* `pause` Temporarily stop the search
-* `resume` Resume the search
-* `abort` Stop the search forever
-
-### Options
-
-All the options that can be passed to Minimatch can also be passed to
-Glob to change pattern matching behavior.  Also, some have been added,
-or have glob-specific ramifications.
-
-All options are false by default, unless otherwise noted.
-
-All options are added to the Glob object, as well.
-
-If you are running many `glob` operations, you can pass a Glob object
-as the `options` argument to a subsequent operation to shortcut some
-`stat` and `readdir` calls.  At the very least, you may pass in shared
-`symlinks`, `statCache`, `realpathCache`, and `cache` options, so that
-parallel glob operations will be sped up by sharing information about
-the filesystem.
-
-* `cwd` The current working directory in which to search.  Defaults
-  to `process.cwd()`.
-* `root` The place where patterns starting with `/` will be mounted
-  onto.  Defaults to `path.resolve(options.cwd, "/")` (`/` on Unix
-  systems, and `C:\` or some such on Windows.)
-* `dot` Include `.dot` files in normal matches and `globstar` matches.
-  Note that an explicit dot in a portion of the pattern will always
-  match dot files.
-* `nomount` By default, a pattern starting with a forward-slash will be
-  "mounted" onto the root setting, so that a valid filesystem path is
-  returned.  Set this flag to disable that behavior.
-* `mark` Add a `/` character to directory matches.  Note that this
-  requires additional stat calls.
-* `nosort` Don't sort the results.
-* `stat` Set to true to stat *all* results.  This reduces performance
-  somewhat, and is completely unnecessary, unless `readdir` is presumed
-  to be an untrustworthy indicator of file existence.
-* `silent` When an unusual error is encountered when attempting to
-  read a directory, a warning will be printed to stderr.  Set the
-  `silent` option to true to suppress these warnings.
-* `strict` When an unusual error is encountered when attempting to
-  read a directory, the process will just continue on in search of
-  other matches.  Set the `strict` option to raise an error in these
-  cases.
-* `cache` See `cache` property above.  Pass in a previously generated
-  cache object to save some fs calls.
-* `statCache` A cache of results of filesystem information, to prevent
-  unnecessary stat calls.  While it should not normally be necessary
-  to set this, you may pass the statCache from one glob() call to the
-  options object of another, if you know that the filesystem will not
-  change between calls.  (See "Race Conditions" below.)
-* `symlinks` A cache of known symbolic links.  You may pass in a
-  previously generated `symlinks` object to save `lstat` calls when
-  resolving `**` matches.
-* `sync` DEPRECATED: use `glob.sync(pattern, opts)` instead.
-* `nounique` In some cases, brace-expanded patterns can result in the
-  same file showing up multiple times in the result set.  By default,
-  this implementation prevents duplicates in the result set.  Set this
-  flag to disable that behavior.
-* `nonull` Set to never return an empty set, instead returning a set
-  containing the pattern itself.  This is the default in glob(3).
-* `debug` Set to enable debug logging in minimatch and glob.
-* `nobrace` Do not expand `{a,b}` and `{1..3}` brace sets.
-* `noglobstar` Do not match `**` against multiple filenames.  (Ie,
-  treat it as a normal `*` instead.)
-* `noext` Do not match `+(a|b)` "extglob" patterns.
-* `nocase` Perform a case-insensitive match.  Note: on
-  case-insensitive filesystems, non-magic patterns will match by
-  default, since `stat` and `readdir` will not raise errors.
-* `matchBase` Perform a basename-only match if the pattern does not
-  contain any slash characters.  That is, `*.js` would be treated as
-  equivalent to `**/*.js`, matching all js files in all directories.
-* `nodir` Do not match directories, only files.  (Note: to match
-  *only* directories, simply put a `/` at the end of the pattern.)
-* `ignore` Add a pattern or an array of glob patterns to exclude matches.
-  Note: `ignore` patterns are *always* in `dot:true` mode, regardless
-  of any other settings.
-* `follow` Follow symlinked directories when expanding `**` patterns.
-  Note that this can result in a lot of duplicate references in the
-  presence of cyclic links.
-* `realpath` Set to true to call `fs.realpath` on all of the results.
-  In the case of a symlink that cannot be resolved, the full absolute
-  path to the matched entry is returned (though it will usually be a
-  broken symlink)
-* `absolute` Set to true to always receive absolute paths for matched
-  files.  Unlike `realpath`, this also affects the values returned in
-  the `match` event.
-
-## Comparisons to other fnmatch/glob implementations
-
-While strict compliance with the existing standards is a worthwhile
-goal, some discrepancies exist between node-glob and other
-implementations, and are intentional.
-
-The double-star character `**` is supported by default, unless the
-`noglobstar` flag is set.  This is supported in the manner of bsdglob
-and bash 4.3, where `**` only has special significance if it is the only
-thing in a path part.  That is, `a/**/b` will match `a/x/y/b`, but
-`a/**b` will not.
-
-Note that symlinked directories are not crawled as part of a `**`,
-though their contents may match against subsequent portions of the
-pattern.  This prevents infinite loops and duplicates and the like.
-
-If an escaped pattern has no matches, and the `nonull` flag is set,
-then glob returns the pattern as-provided, rather than
-interpreting the character escapes.  For example,
-`glob.match([], "\\*a\\?")` will return `"\\*a\\?"` rather than
-`"*a?"`.  This is akin to setting the `nullglob` option in bash, except
-that it does not resolve escaped pattern characters.
-
-If brace expansion is not disabled, then it is performed before any
-other interpretation of the glob pattern.  Thus, a pattern like
-`+(a|{b),c)}`, which would not be valid in bash or zsh, is expanded
-**first** into the set of `+(a|b)` and `+(a|c)`, and those patterns are
-checked for validity.  Since those two are valid, matching proceeds.
-
-### Comments and Negation
-
-Previously, this module let you mark a pattern as a "comment" if it
-started with a `#` character, or a "negated" pattern if it started
-with a `!` character.
-
-These options were deprecated in version 5, and removed in version 6.
-
-To specify things that should not match, use the `ignore` option.
-
-## Windows
-
-**Please only use forward-slashes in glob expressions.**
-
-Though windows uses either `/` or `\` as its path separator, only `/`
-characters are used by this glob implementation.  You must use
-forward-slashes **only** in glob expressions.  Back-slashes will always
-be interpreted as escape characters, not path separators.
-
-Results from absolute patterns such as `/foo/*` are mounted onto the
-root setting using `path.join`.  On windows, this will by default result
-in `/foo/*` matching `C:\foo\bar.txt`.
-
-## Race Conditions
-
-Glob searching, by its very nature, is susceptible to race conditions,
-since it relies on directory walking and such.
-
-As a result, it is possible that a file that exists when glob looks for
-it may have been deleted or modified by the time it returns the result.
-
-As part of its internal implementation, this program caches all stat
-and readdir calls that it makes, in order to cut down on system
-overhead.  However, this also makes it even more susceptible to races,
-especially if the cache or statCache objects are reused between glob
-calls.
-
-Users are thus advised not to use a glob result as a guarantee of
-filesystem state in the face of rapid changes.  For the vast majority
-of operations, this is never a problem.

-# graceful-fs
-
-graceful-fs functions as a drop-in replacement for the fs module,
-making various improvements.
-
-The improvements are meant to normalize behavior across different
-platforms and environments, and to make filesystem access more
-resilient to errors.
-
-## Improvements over [fs module](https://nodejs.org/api/fs.html)
-
-* Queues up `open` and `readdir` calls, and retries them once
-  something closes if there is an EMFILE error from too many file
-  descriptors.
-* fixes `lchmod` for Node versions prior to 0.6.2.
-* implements `fs.lutimes` if possible. Otherwise it becomes a noop.
-* ignores `EINVAL` and `EPERM` errors in `chown`, `fchown` or
-  `lchown` if the user isn't root.
-* makes `lchmod` and `lchown` become noops, if not available.
-* retries reading a file if `read` results in EAGAIN error.
-
-On Windows, it retries renaming a file for up to one second if `EACCESS`
-or `EPERM` error occurs, likely because antivirus software has locked
-the directory.
-
-## USAGE
-
-```javascript
-// use just like fs
-var fs = require('graceful-fs')
-
-// now go and do stuff with it...
-fs.readFileSync('some-file-or-whatever')
-```
-
-## Global Patching
-
-If you want to patch the global fs module (or any other fs-like
-module) you can do this:
-
-```javascript
-// Make sure to read the caveat below.
-var realFs = require('fs')
-var gracefulFs = require('graceful-fs')
-gracefulFs.gracefulify(realFs)
-```
-
-This should only ever be done at the top-level application layer, in
-order to delay on EMFILE errors from any fs-using dependencies.  You
-should **not** do this in a library, because it can cause unexpected
-delays in other parts of the program.
-
-## Changes
-
-This module is fairly stable at this point, and used by a lot of
-things.  That being said, because it implements a subtle behavior
-change in a core part of the node API, even modest changes can be
-extremely breaking, and the versioning is thus biased towards
-bumping the major when in doubt.
-
-The main change between major versions has been switching between
-providing a fully-patched `fs` module vs monkey-patching the node core
-builtin, and the approach by which a non-monkey-patched `fs` was
-created.
-
-The goal is to trade `EMFILE` errors for slower fs operations.  So, if
-you try to open a zillion files, rather than crashing, `open`
-operations will be queued up and wait for something else to `close`.
-
-There are advantages to each approach.  Monkey-patching the fs means
-that no `EMFILE` errors can possibly occur anywhere in your
-application, because everything is using the same core `fs` module,
-which is patched.  However, it can also obviously cause undesirable
-side-effects, especially if the module is loaded multiple times.
-
-Implementing a separate-but-identical patched `fs` module is more
-surgical (and doesn't run the risk of patching multiple times), but
-also imposes the challenge of keeping in sync with the core module.
-
-The current approach loads the `fs` module, and then creates a
-lookalike object that has all the same methods, except a few that are
-patched.  It is safe to use in all versions of Node from 0.8 through
-7.0.
-
-### v4
-
-* Do not monkey-patch the fs module.  This module may now be used as a
-  drop-in dep, and users can opt into monkey-patching the fs builtin
-  if their app requires it.
-
-### v3
-
-* Monkey-patch fs, because the eval approach no longer works on recent
-  node.
-* fixed possible type-error throw if rename fails on windows
-* verify that we *never* get EMFILE errors
-* Ignore ENOSYS from chmod/chown
-* clarify that graceful-fs must be used as a drop-in
-
-### v2.1.0
-
-* Use eval rather than monkey-patching fs.
-* readdir: Always sort the results
-* win32: requeue a file if error has an OK status
-
-### v2.0
-
-* A return to monkey patching
-* wrap process.cwd
-
-### v1.1
-
-* wrap readFile
-* Wrap fs.writeFile.
-* readdir protection
-* Don't clobber the fs builtin
-* Handle fs.read EAGAIN errors by trying again
-* Expose the curOpen counter
-* No-op lchown/lchmod if not implemented
-* fs.rename patch only for win32
-* Patch fs.rename to handle AV software on Windows
-* Close #4 Chown should not fail on einval or eperm if non-root
-* Fix isaacs/fstream#1 Only wrap fs one time
-* Fix #3 Start at 1024 max files, then back off on EMFILE
-* lutimes that doens't blow up on Linux
-* A full on-rewrite using a queue instead of just swallowing the EMFILE error
-* Wrap Read/Write streams as well
-
-### 1.0
-
-* Update engines for node 0.6
-* Be lstat-graceful on Windows
-* first

-# minimatch
-
-A minimal matching utility.
-
-[![Build Status](https://secure.travis-ci.org/isaacs/minimatch.svg)](http://travis-ci.org/isaacs/minimatch)
-
-
-This is the matching library used internally by npm.
-
-It works by converting glob expressions into JavaScript `RegExp`
-objects.
-
-## Usage
-
-```javascript
-var minimatch = require("minimatch")
-
-minimatch("bar.foo", "*.foo") // true!
-minimatch("bar.foo", "*.bar") // false!
-minimatch("bar.foo", "*.+(bar|foo)", { debug: true }) // true, and noisy!
-```
-
-## Features
-
-Supports these glob features:
-
-* Brace Expansion
-* Extended glob matching
-* "Globstar" `**` matching
-
-See:
-
-* `man sh`
-* `man bash`
-* `man 3 fnmatch`
-* `man 5 gitignore`
-
-## Minimatch Class
-
-Create a minimatch object by instantiating the `minimatch.Minimatch` class.
-
-```javascript
-var Minimatch = require("minimatch").Minimatch
-var mm = new Minimatch(pattern, options)
-```
-
-### Properties
-
-* `pattern` The original pattern the minimatch object represents.
-* `options` The options supplied to the constructor.
-* `set` A 2-dimensional array of regexp or string expressions.
-  Each row in the
-  array corresponds to a brace-expanded pattern.  Each item in the row
-  corresponds to a single path-part.  For example, the pattern
-  `{a,b/c}/d` would expand to a set of patterns like:
-
-        [ [ a, d ]
-        , [ b, c, d ] ]
-
-    If a portion of the pattern doesn't have any "magic" in it
-    (that is, it's something like `"foo"` rather than `fo*o?`), then it
-    will be left as a string rather than converted to a regular
-    expression.
-
-* `regexp` Created by the `makeRe` method.  A single regular expression
-  expressing the entire pattern.  This is useful in cases where you wish
-  to use the pattern somewhat like `fnmatch(3)` with `FNM_PATH` enabled.
-* `negate` True if the pattern is negated.
-* `comment` True if the pattern is a comment.
-* `empty` True if the pattern is `""`.
-
-### Methods
-
-* `makeRe` Generate the `regexp` member if necessary, and return it.
-  Will return `false` if the pattern is invalid.
-* `match(fname)` Return true if the filename matches the pattern, or
-  false otherwise.
-* `matchOne(fileArray, patternArray, partial)` Take a `/`-split
-  filename, and match it against a single row in the `regExpSet`.  This
-  method is mainly for internal use, but is exposed so that it can be
-  used by a glob-walker that needs to avoid excessive filesystem calls.
-
-All other methods are internal, and will be called as necessary.
-
-### minimatch(path, pattern, options)
-
-Main export.  Tests a path against the pattern using the options.
-
-```javascript
-var isJS = minimatch(file, "*.js", { matchBase: true })
-```
-
-### minimatch.filter(pattern, options)
-
-Returns a function that tests its
-supplied argument, suitable for use with `Array.filter`.  Example:
-
-```javascript
-var javascripts = fileList.filter(minimatch.filter("*.js", {matchBase: true}))
-```
-
-### minimatch.match(list, pattern, options)
-
-Match against the list of
-files, in the style of fnmatch or glob.  If nothing is matched, and
-options.nonull is set, then return a list containing the pattern itself.
-
-```javascript
-var javascripts = minimatch.match(fileList, "*.js", {matchBase: true}))
-```
-
-### minimatch.makeRe(pattern, options)
-
-Make a regular expression object from the pattern.
-
-## Options
-
-All options are `false` by default.
-
-### debug
-
-Dump a ton of stuff to stderr.
-
-### nobrace
-
-Do not expand `{a,b}` and `{1..3}` brace sets.
-
-### noglobstar
-
-Disable `**` matching against multiple folder names.
-
-### dot
-
-Allow patterns to match filenames starting with a period, even if
-the pattern does not explicitly have a period in that spot.
-
-Note that by default, `a/**/b` will **not** match `a/.d/b`, unless `dot`
-is set.
-
-### noext
-
-Disable "extglob" style patterns like `+(a|b)`.
-
-### nocase
-
-Perform a case-insensitive match.
-
-### nonull
-
-When a match is not found by `minimatch.match`, return a list containing
-the pattern itself if this option is set.  When not set, an empty list
-is returned if there are no matches.
-
-### matchBase
-
-If set, then patterns without slashes will be matched
-against the basename of the path if it contains slashes.  For example,
-`a?b` would match the path `/xyz/123/acb`, but not `/xyz/acb/123`.
-
-### nocomment
-
-Suppress the behavior of treating `#` at the start of a pattern as a
-comment.
-
-### nonegate
-
-Suppress the behavior of treating a leading `!` character as negation.
-
-### flipNegate
-
-Returns from negate expressions the same as if they were not negated.
-(Ie, true on a hit, false on a miss.)
-
-
-## Comparisons to other fnmatch/glob implementations
-
-While strict compliance with the existing standards is a worthwhile
-goal, some discrepancies exist between minimatch and other
-implementations, and are intentional.
-
-If the pattern starts with a `!` character, then it is negated.  Set the
-`nonegate` flag to suppress this behavior, and treat leading `!`
-characters normally.  This is perhaps relevant if you wish to start the
-pattern with a negative extglob pattern like `!(a|B)`.  Multiple `!`
-characters at the start of a pattern will negate the pattern multiple
-times.
-
-If a pattern starts with `#`, then it is treated as a comment, and
-will not match anything.  Use `\#` to match a literal `#` at the
-start of a line, or set the `nocomment` flag to suppress this behavior.
-
-The double-star character `**` is supported by default, unless the
-`noglobstar` flag is set.  This is supported in the manner of bsdglob
-and bash 4.1, where `**` only has special significance if it is the only
-thing in a path part.  That is, `a/**/b` will match `a/x/y/b`, but
-`a/**b` will not.
-
-If an escaped pattern has no matches, and the `nonull` flag is set,
-then minimatch.match returns the pattern as-provided, rather than
-interpreting the character escapes.  For example,
-`minimatch.match([], "\\*a\\?")` will return `"\\*a\\?"` rather than
-`"*a?"`.  This is akin to setting the `nullglob` option in bash, except
-that it does not resolve escaped pattern characters.
-
-If brace expansion is not disabled, then it is performed before any
-other interpretation of the glob pattern.  Thus, a pattern like
-`+(a|{b),c)}`, which would not be valid in bash or zsh, is expanded
-**first** into the set of `+(a|b)` and `+(a|c)`, and those patterns are
-checked for validity.  Since those two are valid, matching proceeds.

-semver(1) -- The semantic versioner for npm
-===========================================
-
-## Usage
-
-    $ npm install semver
-    $ node
-    var semver = require('semver')
-
-    semver.valid('1.2.3') // '1.2.3'
-    semver.valid('a.b.c') // null
-    semver.clean('  =v1.2.3   ') // '1.2.3'
-    semver.satisfies('1.2.3', '1.x || >=2.5.0 || 5.0.0 - 7.2.3') // true
-    semver.gt('1.2.3', '9.8.7') // false
-    semver.lt('1.2.3', '9.8.7') // true
-
-As a command-line utility:
-
-    $ semver -h
-
-    SemVer 5.1.0
-
-    A JavaScript implementation of the http://semver.org/ specification
-    Copyright Isaac Z. Schlueter
-
-    Usage: semver [options] <version> [<version> [...]]
-    Prints valid versions sorted by SemVer precedence
-
-    Options:
-    -r --range <range>
-            Print versions that match the specified range.
-
-    -i --increment [<level>]
-            Increment a version by the specified level.  Level can
-            be one of: major, minor, patch, premajor, preminor,
-            prepatch, or prerelease.  Default level is 'patch'.
-            Only one version may be specified.
-
-    --preid <identifier>
-            Identifier to be used to prefix premajor, preminor,
-            prepatch or prerelease version increments.
-
-    -l --loose
-            Interpret versions and ranges loosely
-
-    Program exits successfully if any valid version satisfies
-    all supplied ranges, and prints all satisfying versions.
-
-    If no satisfying versions are found, then exits failure.
-
-    Versions are printed in ascending order, so supplying
-    multiple versions to the utility will just sort them.
-
-## Versions
-
-A "version" is described by the `v2.0.0` specification found at
-<http://semver.org/>.
-
-A leading `"="` or `"v"` character is stripped off and ignored.
-
-## Ranges
-
-A `version range` is a set of `comparators` which specify versions
-that satisfy the range.
-
-A `comparator` is composed of an `operator` and a `version`.  The set
-of primitive `operators` is:
-
-* `<` Less than
-* `<=` Less than or equal to
-* `>` Greater than
-* `>=` Greater than or equal to
-* `=` Equal.  If no operator is specified, then equality is assumed,
-  so this operator is optional, but MAY be included.
-
-For example, the comparator `>=1.2.7` would match the versions
-`1.2.7`, `1.2.8`, `2.5.3`, and `1.3.9`, but not the versions `1.2.6`
-or `1.1.0`.
-
-Comparators can be joined by whitespace to form a `comparator set`,
-which is satisfied by the **intersection** of all of the comparators
-it includes.
-
-A range is composed of one or more comparator sets, joined by `||`.  A
-version matches a range if and only if every comparator in at least
-one of the `||`-separated comparator sets is satisfied by the version.
-
-For example, the range `>=1.2.7 <1.3.0` would match the versions
-`1.2.7`, `1.2.8`, and `1.2.99`, but not the versions `1.2.6`, `1.3.0`,
-or `1.1.0`.
-
-The range `1.2.7 || >=1.2.9 <2.0.0` would match the versions `1.2.7`,
-`1.2.9`, and `1.4.6`, but not the versions `1.2.8` or `2.0.0`.
-
-### Prerelease Tags
-
-If a version has a prerelease tag (for example, `1.2.3-alpha.3`) then
-it will only be allowed to satisfy comparator sets if at least one
-comparator with the same `[major, minor, patch]` tuple also has a
-prerelease tag.
-
-For example, the range `>1.2.3-alpha.3` would be allowed to match the
-version `1.2.3-alpha.7`, but it would *not* be satisfied by
-`3.4.5-alpha.9`, even though `3.4.5-alpha.9` is technically "greater
-than" `1.2.3-alpha.3` according to the SemVer sort rules.  The version
-range only accepts prerelease tags on the `1.2.3` version.  The
-version `3.4.5` *would* satisfy the range, because it does not have a
-prerelease flag, and `3.4.5` is greater than `1.2.3-alpha.7`.
-
-The purpose for this behavior is twofold.  First, prerelease versions
-frequently are updated very quickly, and contain many breaking changes
-that are (by the author's design) not yet fit for public consumption.
-Therefore, by default, they are excluded from range matching
-semantics.
-
-Second, a user who has opted into using a prerelease version has
-clearly indicated the intent to use *that specific* set of
-alpha/beta/rc versions.  By including a prerelease tag in the range,
-the user is indicating that they are aware of the risk.  However, it
-is still not appropriate to assume that they have opted into taking a
-similar risk on the *next* set of prerelease versions.
-
-#### Prerelease Identifiers
-
-The method `.inc` takes an additional `identifier` string argument that
-will append the value of the string as a prerelease identifier:
-
-```javascript
-> semver.inc('1.2.3', 'prerelease', 'beta')
-'1.2.4-beta.0'
-```
-
-command-line example:
-
-```shell
-$ semver 1.2.3 -i prerelease --preid beta
-1.2.4-beta.0
-```
-
-Which then can be used to increment further:
-
-```shell
-$ semver 1.2.4-beta.0 -i prerelease
-1.2.4-beta.1
-```
-
-### Advanced Range Syntax
-
-Advanced range syntax desugars to primitive comparators in
-deterministic ways.
-
-Advanced ranges may be combined in the same way as primitive
-comparators using white space or `||`.
-
-#### Hyphen Ranges `X.Y.Z - A.B.C`
-
-Specifies an inclusive set.
-
-* `1.2.3 - 2.3.4` := `>=1.2.3 <=2.3.4`
-
-If a partial version is provided as the first version in the inclusive
-range, then the missing pieces are replaced with zeroes.
-
-* `1.2 - 2.3.4` := `>=1.2.0 <=2.3.4`
-
-If a partial version is provided as the second version in the
-inclusive range, then all versions that start with the supplied parts
-of the tuple are accepted, but nothing that would be greater than the
-provided tuple parts.
-
-* `1.2.3 - 2.3` := `>=1.2.3 <2.4.0`
-* `1.2.3 - 2` := `>=1.2.3 <3.0.0`
-
-#### X-Ranges `1.2.x` `1.X` `1.2.*` `*`
-
-Any of `X`, `x`, or `*` may be used to "stand in" for one of the
-numeric values in the `[major, minor, patch]` tuple.
-
-* `*` := `>=0.0.0` (Any version satisfies)
-* `1.x` := `>=1.0.0 <2.0.0` (Matching major version)
-* `1.2.x` := `>=1.2.0 <1.3.0` (Matching major and minor versions)
-
-A partial version range is treated as an X-Range, so the special
-character is in fact optional.
-
-* `""` (empty string) := `*` := `>=0.0.0`
-* `1` := `1.x.x` := `>=1.0.0 <2.0.0`
-* `1.2` := `1.2.x` := `>=1.2.0 <1.3.0`
-
-#### Tilde Ranges `~1.2.3` `~1.2` `~1`
-
-Allows patch-level changes if a minor version is specified on the
-comparator.  Allows minor-level changes if not.
-
-* `~1.2.3` := `>=1.2.3 <1.(2+1).0` := `>=1.2.3 <1.3.0`
-* `~1.2` := `>=1.2.0 <1.(2+1).0` := `>=1.2.0 <1.3.0` (Same as `1.2.x`)
-* `~1` := `>=1.0.0 <(1+1).0.0` := `>=1.0.0 <2.0.0` (Same as `1.x`)
-* `~0.2.3` := `>=0.2.3 <0.(2+1).0` := `>=0.2.3 <0.3.0`
-* `~0.2` := `>=0.2.0 <0.(2+1).0` := `>=0.2.0 <0.3.0` (Same as `0.2.x`)
-* `~0` := `>=0.0.0 <(0+1).0.0` := `>=0.0.0 <1.0.0` (Same as `0.x`)
-* `~1.2.3-beta.2` := `>=1.2.3-beta.2 <1.3.0` Note that prereleases in
-  the `1.2.3` version will be allowed, if they are greater than or
-  equal to `beta.2`.  So, `1.2.3-beta.4` would be allowed, but
-  `1.2.4-beta.2` would not, because it is a prerelease of a
-  different `[major, minor, patch]` tuple.
-
-#### Caret Ranges `^1.2.3` `^0.2.5` `^0.0.4`
-
-Allows changes that do not modify the left-most non-zero digit in the
-`[major, minor, patch]` tuple.  In other words, this allows patch and
-minor updates for versions `1.0.0` and above, patch updates for
-versions `0.X >=0.1.0`, and *no* updates for versions `0.0.X`.
-
-Many authors treat a `0.x` version as if the `x` were the major
-"breaking-change" indicator.
-
-Caret ranges are ideal when an author may make breaking changes
-between `0.2.4` and `0.3.0` releases, which is a common practice.
-However, it presumes that there will *not* be breaking changes between
-`0.2.4` and `0.2.5`.  It allows for changes that are presumed to be
-additive (but non-breaking), according to commonly observed practices.
-
-* `^1.2.3` := `>=1.2.3 <2.0.0`
-* `^0.2.3` := `>=0.2.3 <0.3.0`
-* `^0.0.3` := `>=0.0.3 <0.0.4`
-* `^1.2.3-beta.2` := `>=1.2.3-beta.2 <2.0.0` Note that prereleases in
-  the `1.2.3` version will be allowed, if they are greater than or
-  equal to `beta.2`.  So, `1.2.3-beta.4` would be allowed, but
-  `1.2.4-beta.2` would not, because it is a prerelease of a
-  different `[major, minor, patch]` tuple.
-* `^0.0.3-beta` := `>=0.0.3-beta <0.0.4`  Note that prereleases in the
-  `0.0.3` version *only* will be allowed, if they are greater than or
-  equal to `beta`.  So, `0.0.3-pr.2` would be allowed.
-
-When parsing caret ranges, a missing `patch` value desugars to the
-number `0`, but will allow flexibility within that value, even if the
-major and minor versions are both `0`.
-
-* `^1.2.x` := `>=1.2.0 <2.0.0`
-* `^0.0.x` := `>=0.0.0 <0.1.0`
-* `^0.0` := `>=0.0.0 <0.1.0`
-
-A missing `minor` and `patch` values will desugar to zero, but also
-allow flexibility within those values, even if the major version is
-zero.
-
-* `^1.x` := `>=1.0.0 <2.0.0`
-* `^0.x` := `>=0.0.0 <1.0.0`
-
-### Range Grammar
-
-Putting all this together, here is a Backus-Naur grammar for ranges,
-for the benefit of parser authors:
-
-```bnf
-range-set  ::= range ( logical-or range ) *
-logical-or ::= ( ' ' ) * '||' ( ' ' ) *
-range      ::= hyphen | simple ( ' ' simple ) * | ''
-hyphen     ::= partial ' - ' partial
-simple     ::= primitive | partial | tilde | caret
-primitive  ::= ( '<' | '>' | '>=' | '<=' | '=' | ) partial
-partial    ::= xr ( '.' xr ( '.' xr qualifier ? )? )?
-xr         ::= 'x' | 'X' | '*' | nr
-nr         ::= '0' | ['1'-'9'] ( ['0'-'9'] ) *
-tilde      ::= '~' partial
-caret      ::= '^' partial
-qualifier  ::= ( '-' pre )? ( '+' build )?
-pre        ::= parts
-build      ::= parts
-parts      ::= part ( '.' part ) *
-part       ::= nr | [-0-9A-Za-z]+
-```
-
-## Functions
-
-All methods and classes take a final `loose` boolean argument that, if
-true, will be more forgiving about not-quite-valid semver strings.
-The resulting output will always be 100% strict, of course.
-
-Strict-mode Comparators and Ranges will be strict about the SemVer
-strings that they parse.
-
-* `valid(v)`: Return the parsed version, or null if it's not valid.
-* `inc(v, release)`: Return the version incremented by the release
-  type (`major`,   `premajor`, `minor`, `preminor`, `patch`,
-  `prepatch`, or `prerelease`), or null if it's not valid
-  * `premajor` in one call will bump the version up to the next major
-    version and down to a prerelease of that major version.
-    `preminor`, and `prepatch` work the same way.
-  * If called from a non-prerelease version, the `prerelease` will work the
-    same as `prepatch`. It increments the patch version, then makes a
-    prerelease. If the input version is already a prerelease it simply
-    increments it.
-* `prerelease(v)`: Returns an array of prerelease components, or null
-  if none exist. Example: `prerelease('1.2.3-alpha.1') -> ['alpha', 1]`
-* `major(v)`: Return the major version number.
-* `minor(v)`: Return the minor version number.
-* `patch(v)`: Return the patch version number.
-
-### Comparison
-
-* `gt(v1, v2)`: `v1 > v2`
-* `gte(v1, v2)`: `v1 >= v2`
-* `lt(v1, v2)`: `v1 < v2`
-* `lte(v1, v2)`: `v1 <= v2`
-* `eq(v1, v2)`: `v1 == v2` This is true if they're logically equivalent,
-  even if they're not the exact same string.  You already know how to
-  compare strings.
-* `neq(v1, v2)`: `v1 != v2` The opposite of `eq`.
-* `cmp(v1, comparator, v2)`: Pass in a comparison string, and it'll call
-  the corresponding function above.  `"==="` and `"!=="` do simple
-  string comparison, but are included for completeness.  Throws if an
-  invalid comparison string is provided.
-* `compare(v1, v2)`: Return `0` if `v1 == v2`, or `1` if `v1` is greater, or `-1` if
-  `v2` is greater.  Sorts in ascending order if passed to `Array.sort()`.
-* `rcompare(v1, v2)`: The reverse of compare.  Sorts an array of versions
-  in descending order when passed to `Array.sort()`.
-* `diff(v1, v2)`: Returns difference between two versions by the release type
-  (`major`, `premajor`, `minor`, `preminor`, `patch`, `prepatch`, or `prerelease`),
-  or null if the versions are the same.
-
-
-### Ranges
-
-* `validRange(range)`: Return the valid range or null if it's not valid
-* `satisfies(version, range)`: Return true if the version satisfies the
-  range.
-* `maxSatisfying(versions, range)`: Return the highest version in the list
-  that satisfies the range, or `null` if none of them do.
-* `minSatisfying(versions, range)`: Return the lowest version in the list
-  that satisfies the range, or `null` if none of them do.
-* `gtr(version, range)`: Return `true` if version is greater than all the
-  versions possible in the range.
-* `ltr(version, range)`: Return `true` if version is less than all the
-  versions possible in the range.
-* `outside(version, range, hilo)`: Return true if the version is outside
-  the bounds of the range in either the high or low direction.  The
-  `hilo` argument must be either the string `'>'` or `'<'`.  (This is
-  the function called by `gtr` and `ltr`.)
-
-Note that, since ranges may be non-contiguous, a version might not be
-greater than a range, less than a range, *or* satisfy a range!  For
-example, the range `1.2 <1.2.9 || >2.0.0` would have a hole from `1.2.9`
-until `2.0.0`, so the version `1.2.10` would not be greater than the
-range (because `2.0.1` satisfies, which is higher), nor less than the
-range (since `1.2.8` satisfies, which is lower), and it also does not
-satisfy the range.
-
-If you want to know if a version satisfies or does not satisfy a
-range, use the `satisfies(version, range)` function.

-
-Node-sass is a library that provides binding for Node.js to [LibSass], the C version of the popular stylesheet preprocessor, Sass.
-
-It allows you to natively compile .scss files to css at incredible speed and automatically via a connect middleware.
-
-Find it on npm: <https://www.npmjs.com/package/node-sass>
-
-Follow @nodesass on twitter for release updates: <https://twitter.com/nodesass>
-
-## Install
-
-```shell
-npm install node-sass
-```
-
-Some users have reported issues installing on Ubuntu due to `node` being registered to another package. [Follow the official NodeJS docs](https://github.com/nodesource/distributions/blob/master/README.md#debinstall) to install NodeJS so that `#!/usr/bin/env node` correctly resolves.
-
-Compiling on Windows machines requires the [node-gyp prerequisites](https://github.com/nodejs/node-gyp#on-windows).
-
-Are you seeing the following error? Check out our [Troubleshooting guide](https://github.com/sass/node-sass/blob/master/TROUBLESHOOTING.md#installing-node-sass-4x-with-node--4).**
-
-```
-SyntaxError: Use of const in strict mode.
-```
-
-**Having installation troubles? Check out our [Troubleshooting guide](https://github.com/sass/node-sass/blob/master/TROUBLESHOOTING.md).**
-
-### Install from mirror in China

-```javascript
-var sass = require('node-sass');
-sass.render({
-  file: scss_filename,
-  [, options..]
-}, function(err, result) { /*...*/ });
-// OR
-var result = sass.renderSync({
-  data: scss_content
-  [, options..]
-});
-```
-
-## Options
-
-### file
-
-* Type: `String`
-* Default: `null`
-
-**Special**: `file` or `data` must be specified
-
-Path to a file for [LibSass] to compile.
-
-### data
-
-* Type: `String`
-* Default: `null`
-
-**Special**: `file` or `data` must be specified
-
-A string to pass to [LibSass] to compile. It is recommended that you use `includePaths` in conjunction with this so that [LibSass] can find files when using the `@import` directive.
-
-### importer (>= v2.0.0) - _experimental_
-
-**This is an experimental LibSass feature. Use with caution.**
-
-* Type: `Function | Function[]` signature `function(url, prev, done)`
-* Default: `undefined`
-
-Function Parameters and Information:
-
-* `url (String)` - the path in import **as-is**, which [LibSass] encountered
-* `prev (String)` - the previously resolved path
-* `done (Function)` - a callback function to invoke on async completion, takes an object literal containing
-  * `file (String)` - an alternate path for [LibSass] to use **OR**
-  * `contents (String)` - the imported contents (for example, read from memory or the file system)
-
-Handles when [LibSass] encounters the `@import` directive. A custom importer allows extension of the [LibSass] engine in both a synchronous and asynchronous manner. In both cases, the goal is to either `return` or call `done()` with an object literal. Depending on the value of the object literal, one of two things will happen.
-
-When returning or calling `done()` with `{ file: "String" }`, the new file path will be assumed for the `@import`. It's recommended to be mindful of the value of `prev` in instances where relative path resolution may be required.
-
-When returning or calling `done()` with `{ contents: "String" }`, the string value will be used as if the file was read in through an external source.
-
-Starting from v3.0.0:
-
-* `this` refers to a contextual scope for the immediate run of `sass.render` or `sass.renderSync`
-
-* importers can return error and LibSass will emit that error in response. For instance:
-
-  ```javascript
-  done(new Error('doesn\'t exist!'));
-  // or return synchronously
-  return new Error('nothing to do here');
-  ```
-
-* importer can be an array of functions, which will be called by LibSass in the order of their occurrence in array. This helps user specify special importer for particular kind of path (filesystem, http). If an importer does not want to handle a particular path, it should return `null`. See [functions section](#functions--v300---experimental) for more details on Sass types.
-
-### functions (>= v3.0.0) - _experimental_
-
-**This is an experimental LibSass feature. Use with caution.**
-
-`functions` is an `Object` that holds a collection of custom functions that may be invoked by the sass files being compiled. They may take zero or more input parameters and must return a value either synchronously (`return ...;`) or asynchronously (`done();`). Those parameters will be instances of one of the constructors contained in the `require('node-sass').types` hash. The return value must be of one of these types as well. See the list of available types below:
-
-#### types.Number(value [, unit = ""])
-
-* `getValue()`/ `setValue(value)` : gets / sets the numerical portion of the number
-* `getUnit()` / `setUnit(unit)` : gets / sets the unit portion of the number
-
-#### types.String(value)
-
-* `getValue()` / `setValue(value)` : gets / sets the enclosed string
-
-#### types.Color(r, g, b [, a = 1.0]) or types.Color(argb)
-
-* `getR()` / `setR(value)` : red component (integer from `0` to `255`)
-* `getG()` / `setG(value)` : green component (integer from `0` to `255`)
-* `getB()` / `setB(value)` : blue component (integer from `0` to `255`)
-* `getA()` / `setA(value)` : alpha component (number from `0` to `1.0`)
-
-Example:
-
-```javascript
-var Color = require('node-sass').types.Color,
-  c1 = new Color(255, 0, 0),
-  c2 = new Color(0xff0088cc);
-```
-
-#### types.Boolean(value)
-
-* `getValue()` : gets the enclosed boolean
-* `types.Boolean.TRUE` : Singleton instance of `types.Boolean` that holds "true"
-* `types.Boolean.FALSE` : Singleton instance of `types.Boolean` that holds "false"
-
-#### types.List(length [, commaSeparator = true])
-
-* `getValue(index)` / `setValue(index, value)` : `value` must itself be an instance of one of the constructors in `sass.types`.
-* `getSeparator()` / `setSeparator(isComma)` : whether to use commas as a separator
-* `getLength()`
-
-#### types.Map(length)
-
-* `getKey(index)` / `setKey(index, value)`
-* `getValue(index)` / `setValue(index, value)`
-* `getLength()`
-
-#### types.Null()
-
-* `types.Null.NULL` : Singleton instance of `types.Null`.
-
-#### Example
-
-```javascript
-sass.renderSync({
-  data: '#{headings(2,5)} { color: #08c; }',
-  functions: {
-    'headings($from: 0, $to: 6)': function(from, to) {
-      var i, f = from.getValue(), t = to.getValue(),
-          list = new sass.types.List(t - f + 1);
-
-      for (i = f; i <= t; i++) {
-        list.setValue(i - f, new sass.types.String('h' + i));
-      }
-
-      return list;
-    }
-  }
-});
-```
-
-### includePaths
-
-* Type: `Array<String>`
-* Default: `[]`
-
-An array of paths that [LibSass] can look in to attempt to resolve your `@import` declarations. When using `data`, it is recommended that you use this.
-
-### indentedSyntax
-
-* Type: `Boolean`
-* Default: `false`
-
-`true` values enable [Sass Indented Syntax](https://sass-lang.com/documentation/file.INDENTED_SYNTAX.html) for parsing the data string or file.
-
-__Note:__ node-sass/libsass will compile a mixed library of scss and indented syntax (.sass) files with the Default setting (false) as long as .sass and .scss extensions are used in filenames.
-
-### indentType (>= v3.0.0)
-
-* Type: `String`
-* Default: `space`
-
-Used to determine whether to use space or tab character for indentation.
-
-### indentWidth (>= v3.0.0)
-
-* Type: `Number`
-* Default: `2`
-* Maximum: `10`
-
-Used to determine the number of spaces or tabs to be used for indentation.
-
-### linefeed (>= v3.0.0)
-
-* Type: `String`
-* Default: `lf`
-
-Used to determine whether to use `cr`, `crlf`, `lf` or `lfcr` sequence for line break.
-
-### omitSourceMapUrl
-
-* Type: `Boolean`
-* Default: `false`
-
-**Special:** When using this, you should also specify `outFile` to avoid unexpected behavior.
-
-`true` values disable the inclusion of source map information in the output file.
-
-### outFile
-
-* Type: `String | null`
-* Default: `null`
-
-**Special:** Required when `sourceMap` is a truthy value
-
-Specify the intended location of the output file. Strongly recommended when outputting source maps so that they can properly refer back to their intended files.
-
-**Attention** enabling this option will **not** write the file on disk for you, it's for internal reference purpose only (to generate the map for example).
-
-Example on how to write it on the disk
-
-```javascript
-sass.render({
-    ...
-    outFile: yourPathTotheFile,
-  }, function(error, result) { // node-style callback from v3.0.0 onwards
-    if(!error){
-      // No errors during the compilation, write this result on the disk
-      fs.writeFile(yourPathTotheFile, result.css, function(err){
-        if(!err){
-          //file written on disk
-        }
-      });
-    }
-  });
-});
-```
-
-### outputStyle
-
-* Type: `String`
-* Default: `nested`
-* Values: `nested`, `expanded`, `compact`, `compressed`
-
-Determines the output format of the final CSS style.
-
-### precision
-
-* Type: `Integer`
-* Default: `5`
-
-Used to determine how many digits after the decimal will be allowed. For instance, if you had a decimal number of `1.23456789` and a precision of `5`, the result will be `1.23457` in the final CSS.
-
-### sourceComments
-
-* Type: `Boolean`
-* Default: `false`
-
-`true` Enables the line number and file where a selector is defined to be emitted into the compiled CSS as a comment. Useful for debugging, especially when using imports and mixins.
-
-### sourceMap
-
-* Type: `Boolean | String | undefined`
-* Default: `undefined`
-
-Enables source map generation during `render` and `renderSync`.
-
-When `sourceMap === true`, the value of `outFile` is used as the target output location for the source map with the suffix `.map` appended. If no `outFile` is set, `sourceMap` parameter is ignored.
-
-When `typeof sourceMap === "string"`, the value of `sourceMap` will be used as the writing location for the file.
-
-### sourceMapContents
-
-* Type: `Boolean`
-* Default: `false`
-
-`true` includes the `contents` in the source map information
-
-### sourceMapEmbed
-
-* Type: `Boolean`
-* Default: `false`
-
-`true` embeds the source map as a data URI
-
-### sourceMapRoot
-
-* Type: `String`
-* Default: `undefined`
-
-the value will be emitted as `sourceRoot` in the source map information
-
-## `render` Callback (>= v3.0.0)
-
-node-sass supports standard node style asynchronous callbacks with the signature of `function(err, result)`. In error conditions, the `error` argument is populated with the error object. In success conditions, the `result` object is populated with an object describing the result of the render call.
-
-### Error Object
-
-* `message` (String) - The error message.
-* `line` (Number) - The line number of error.
-* `column` (Number) - The column number of error.
-* `status` (Number) - The status code.
-* `file` (String) - The filename of error. In case `file` option was not set (in favour of `data`), this will reflect the value `stdin`.
-
-### Result Object
-
-* `css` (Buffer) - The compiled CSS. Write this to a file, or serve it out as needed.
-* `map` (Buffer) - The source map
-* `stats` (Object) - An object containing information about the compile. It contains the following keys:
-  * `entry` (String) - The path to the scss file, or `data` if the source was not a file
-  * `start` (Number) - Date.now() before the compilation
-  * `end` (Number) - Date.now() after the compilation
-  * `duration` (Number) - *end* - *start*
-  * `includedFiles` (Array) - Absolute paths to all related scss files in no particular order.
-
-### Examples
-
-```javascript
-var sass = require('node-sass');
-sass.render({
-  file: '/path/to/myFile.scss',
-  data: 'body{background:blue; a{color:black;}}',
-  importer: function(url, prev, done) {
-    // url is the path in import as is, which LibSass encountered.
-    // prev is the previously resolved path.
-    // done is an optional callback, either consume it or return value synchronously.
-    // this.options contains this options hash, this.callback contains the node-style callback
-    someAsyncFunction(url, prev, function(result){
-      done({
-        file: result.path, // only one of them is required, see section Special Behaviours.
-        contents: result.data
-      });
-    });
-    // OR
-    var result = someSyncFunction(url, prev);
-    return {file: result.path, contents: result.data};
-  },
-  includePaths: [ 'lib/', 'mod/' ],
-  outputStyle: 'compressed'
-}, function(error, result) { // node-style callback from v3.0.0 onwards
-  if (error) {
-    console.log(error.status); // used to be "code" in v2x and below
-    console.log(error.column);
-    console.log(error.message);
-    console.log(error.line);
-  }
-  else {
-    console.log(result.css.toString());
-
-    console.log(result.stats);
-
-    console.log(result.map.toString());
-    // or better
-    console.log(JSON.stringify(result.map)); // note, JSON.stringify accepts Buffer too
-  }
-});
-// OR
-var result = sass.renderSync({
-  file: '/path/to/file.scss',
-  data: 'body{background:blue; a{color:black;}}',
-  outputStyle: 'compressed',
-  outFile: '/to/my/output.css',
-  sourceMap: true, // or an absolute or relative (to outFile) path
-  importer: function(url, prev, done) {
-    // url is the path in import as is, which LibSass encountered.
-    // prev is the previously resolved path.
-    // done is an optional callback, either consume it or return value synchronously.
-    // this.options contains this options hash
-    someAsyncFunction(url, prev, function(result){
-      done({
-        file: result.path, // only one of them is required, see section Special Behaviours.
-        contents: result.data
-      });
-    });
-    // OR
-    var result = someSyncFunction(url, prev);
-    return {file: result.path, contents: result.data};
-  }
-});
-
-console.log(result.css);
-console.log(result.map);
-console.log(result.stats);
-```
-
-### Special behaviours
-
-* In the case that both `file` and `data` options are set, node-sass will give precedence to `data` and use `file` to calculate paths in sourcemaps.
-
-### Version information (>= v2.0.0)
-
-Both `node-sass` and `libsass` version info is now exposed via the `info` method:
-
-```javascript
-var sass = require('node-sass');
-
-console.log(sass.info);
-
-/*
-  it will output something like:
-
-  node-sass       2.0.1   (Wrapper)       [JavaScript]
-  libsass         3.1.0   (Sass Compiler) [C/C++]
-*/
-```
-
-Since node-sass >=v3.0.0 LibSass version is determined at run time.
-
-## Integrations
-
-Listing of community uses of node-sass in build tools and frameworks.

-
-## Example App
-
-There is also an example connect app here: <https://github.com/andrew/node-sass-example>
-
-## Rebuilding binaries
-
-Node-sass includes pre-compiled binaries for popular platforms, to add a binary for your platform follow these steps:
-
-Check out the project:
-
-```bash
-git clone --recursive https://github.com/sass/node-sass.git
-cd node-sass
-npm install
-node scripts/build -f  # use -d switch for debug release
-# if succeeded, it will generate and move
-# the binary in vendor directory.
-```
-
-## Command Line Interface
-
-The interface for command-line usage is fairly simplistic at this stage, as seen in the following usage section.
-
-Output will be sent to stdout if the `--output` flag is omitted.
-
-### Usage
-
- `node-sass [options] <input> [output]`
- Or:
- `cat <input> | node-sass > output`
-
-Example:
-
-`node-sass src/style.scss dest/style.css`
-
- **Options:**
-
-```bash
-    -w, --watch                Watch a directory or file
-    -r, --recursive            Recursively watch directories or files
-    -o, --output               Output directory
-    -x, --omit-source-map-url  Omit source map URL comment from output
-    -i, --indented-syntax      Treat data from stdin as sass code (versus scss)
-    -q, --quiet                Suppress log output except on error
-    -v, --version              Prints version info
-    --output-style             CSS output style (nested | expanded | compact | compressed)
-    --indent-type              Indent type for output CSS (space | tab)
-    --indent-width             Indent width; number of spaces or tabs (maximum value: 10)
-    --linefeed                 Linefeed style (cr | crlf | lf | lfcr)
-    --source-comments          Include debug info in output
-    --source-map               Emit source map
-    --source-map-contents      Embed include contents in map
-    --source-map-embed         Embed sourceMappingUrl as data URI
-    --source-map-root          Base path, will be emitted in source-map as is
-    --include-path             Path to look for imported files
-    --follow                   Follow symlinked directories
-    --precision                The amount of precision allowed in decimal numbers
-    --error-bell               Output a bell character on errors
-    --importer                 Path to .js file containing custom importer
-    --functions                Path to .js file containing custom functions
-    --help                     Print usage info
-```
-
-The `input` can be either a single `.scss` or `.sass`, or a directory. If the input is a directory the `--output` flag must also be supplied.
-
-Also, note `--importer` takes the (absolute or relative to pwd) path to a js file, which needs to have a default `module.exports` set to the importer function. See our test [fixtures](https://github.com/sass/node-sass/tree/974f93e76ddd08ea850e3e663cfe64bb6a059dd3/test/fixtures/extras) for example.
-
-The `--source-map` option accepts a boolean value, in which case it replaces destination extension with `.css.map`. It also accepts path to `.map` file and even path to the desired directory.
-When compiling a directory `--source-map` can either be a boolean value or a directory.
-
-## Binary configuration parameters
-
-node-sass supports different configuration parameters to change settings related to the sass binary such as binary name, binary path or alternative download path. Following parameters are supported by node-sass:
-
-Variable name    | .npmrc parameter | Process argument   | Value
------------------|------------------|--------------------|------
-SASS_BINARY_NAME | sass_binary_name | --sass-binary-name | path
-SASS_BINARY_SITE | sass_binary_site | --sass-binary-site | URL
-SASS_BINARY_PATH | sass_binary_path | --sass-binary-path | path
-SASS_BINARY_DIR  | sass_binary_dir  | --sass-binary-dir  | path
-
-These parameters can be used as environment variable:
-
-* E.g. `export SASS_BINARY_SITE=http://example.com/`
-
-As local or global [.npmrc](https://docs.npmjs.com/misc/config) configuration file:
-
-* E.g. `sass_binary_site=http://example.com/`
-
-As a process argument:
-
-* E.g. `npm install node-sass --sass-binary-site=http://example.com/`
-
-## Post-install Build
-
-Install runs only two Mocha tests to see if your machine can use the pre-built [LibSass] which will save some time during install. If any tests fail it will build from source.

-# gaze [![Build Status](http://img.shields.io/travis/shama/gaze.svg)](https://travis-ci.org/shama/gaze) [![Build status](https://ci.appveyor.com/api/projects/status/vtx65w9eg511tgo4)](https://ci.appveyor.com/project/shama/gaze)
-
-A globbing `fs.watch` wrapper built from the best parts of other fine watch libs.  
-Compatible with Node.js >= 4.x, Windows, macOS, and Linux.
-
-![gaze](http://dontkry.com/images/repos/gaze.png)
-
-[![NPM](https://nodei.co/npm/gaze.png?downloads=true)](https://nodei.co/npm/gaze/)
-
-## Usage
-Install the module with: `npm install gaze` or place into your `package.json`
-and run `npm install`.
-
-```javascript
-var gaze = require('gaze');
-
-// Watch all .js files/dirs in process.cwd()
-gaze('**/*.js', function(err, watcher) {
-  // Files have all started watching
-  // watcher === this
-
-  // Get all watched files
-  var watched = this.watched();
-
-  // On file changed
-  this.on('changed', function(filepath) {
-    console.log(filepath + ' was changed');
-  });
-
-  // On file added
-  this.on('added', function(filepath) {
-    console.log(filepath + ' was added');
-  });
-
-  // On file deleted
-  this.on('deleted', function(filepath) {
-    console.log(filepath + ' was deleted');
-  });
-
-  // On changed/added/deleted
-  this.on('all', function(event, filepath) {
-    console.log(filepath + ' was ' + event);
-  });
-
-  // Get watched files with relative paths
-  var files = this.relative();
-});
-
-// Also accepts an array of patterns
-gaze(['stylesheets/*.css', 'images/**/*.png'], function() {
-  // Add more patterns later to be watched
-  this.add(['js/*.js']);
-});
-```
-
-### Alternate Interface
-
-```javascript
-var Gaze = require('gaze').Gaze;
-
-var gaze = new Gaze('**/*');
-
-// Files have all started watching
-gaze.on('ready', function(watcher) { });
-
-// A file has been added/changed/deleted has occurred
-gaze.on('all', function(event, filepath) { });
-```
-
-### Errors
-
-```javascript
-gaze('**/*', function(error, watcher) {
-  if (error) {
-    // Handle error if it occurred while starting up
-  }
-});
-
-// Or with the alternative interface
-var gaze = new Gaze();
-gaze.on('error', function(error) {
-  // Handle error here
-});
-gaze.add('**/*');
-```
-
-### Minimatch / Glob
-
-See [isaacs's `minimatch`](https://github.com/isaacs/minimatch) for more
-information on glob patterns.
-
-## Documentation
-
-### gaze([patterns, options, callback])
-
-* `patterns` {`String`|`Array`} File patterns to be matched
-* `options` {`Object`}
-* `callback` {`Function`}
-  * `err` {`Error` | `null`}
-  * `watcher` {`Object`} Instance of the `Gaze` watcher
-
-### Class: `gaze.Gaze`
-
-Create a `Gaze` object by instancing the `gaze.Gaze` class.
-
-```javascript
-var Gaze = require('gaze').Gaze;
-var gaze = new Gaze(pattern, options, callback);
-```
-
-#### Properties
-
-* `options` The options object passed in.
-  * `interval` {integer} Interval to pass to `fs.watchFile`
-  * `debounceDelay` {integer} Delay for events called in succession for the same
-    file/event in milliseconds
-  * `mode` {string} Force the watch mode. Either `'auto'` (default), `'watch'` (force native events), or `'poll'` (force stat polling).
-  * `cwd` {string} The current working directory to base file patterns from. Default is `process.cwd()`.
-
-#### Events
-
-* `ready(watcher)` When files have been globbed and watching has begun.
-* `all(event, filepath)` When an `added`, `changed`, `renamed`, or `deleted` event occurs.
-* `added(filepath)` When a file has been added to a watch directory.
-* `changed(filepath)` When a file has been changed.
-* `deleted(filepath)` When a file has been deleted.
-* `renamed(newPath, oldPath)` When a file has been renamed.
-* `end()` When the watcher is closed and watches have been removed.
-* `error(err)` When an error occurs.
-* `nomatch` When no files have been matched.
-
-#### Methods
-
-* `emit(event, [...])` Wrapper for `EventEmitter.emit`.
-  `added`|`changed`|`renamed`|`deleted` events will also trigger the `all` event.
-* `close()` Unwatch all files and reset the watch instance.
-* `add(patterns, callback)` Adds file(s) `patterns` to be watched.
-* `remove(filepath)` Removes a file or directory from being watched. Does not
-  recurse directories.
-* `watched()` Returns the currently watched files.
-* `relative([dir, unixify])` Returns the currently watched files with relative paths.
-  * `dir` {string} Only return relative files for this directory.
-  * `unixify` {boolean} Return paths with `/` instead of `\\` if on Windows.

-## Release History
-* 1.1.3 - Fix for Node 10 support (@aredridel). Officially dropping support for Node < 4.
-* 1.1.2 - Prevent more `ENOENT` errors from escaping (@alexgorbatchev).
-* 1.1.1 - Prevent `fs.watch` errors from escaping error handler (@rosen-vladimirov). Fix `_addToWatched` without `path.sep` (@wyicwx).

-* 0.6.4 - Catch and emit `error` from `readdir` (@oconnore). Fix for `0 maxListeners`. Use `graceful-fs` to avoid `EMFILE` errors in other places `fs` is used. Better method to determine if `pathwatcher` was built. Fix keeping process alive too much, only init `pathwatcher` if a file is being watched. Set min required to Windows Vista when building on Windows (@pvolok).
-* 0.6.3 - Add support for Node.js v0.11

-* 0.6.1 - Fix for absolute paths.
-* 0.6.0 - Uses native OS events (fork of `pathwatcher`) but can fall back to stat polling. Everything is async to avoid blocking, including `relative()` and `watched()`. Better error handling. Update to `globule@0.2.0`. No longer watches `cwd` by default. Added `mode` option. Better `EMFILE` message. Avoids `ENOENT` errors with symlinks. All constructor arguments are optional.
-* 0.5.2 - Fix for `ENOENT` error with non-existent symlinks [BACKPORTED].
-* 0.5.1 - Use `setImmediate` (`process.nextTick` for Node.js v0.8) to defer `ready`/`nomatch` events (@amasad).
-* 0.5.0 - Process is now kept alive while watching files. Emits a `nomatch` event when no files are matching.
-* 0.4.3 - Track file additions in newly created folders (@brett-shwom).

-* 0.4.0 - Drop support for Node.js v0.6. Use `globule` for file matching. Avoid Node.js v0.10 `path.resolve`/`join` errors. Register new files when added to non-existent folder. Multiple instances can now poll the same files (@jpommerening).
-* 0.3.4 - Code clean up. Fix “`path must be strings`” errors (@groner). Fix incorrect `added` events (@groner).
-* 0.3.3 - Fix for multiple patterns with negate.
-* 0.3.2 - Emit `end` before `removeAllListeners`.
-* 0.3.1 - Fix `added` events within subfolder patterns.
-* 0.3.0 - Handle safewrite events, `forceWatchMethod` option removed, bug fixes and watch optimizations (@rgaskill).
-* 0.2.2 - Fix issue where subsequent `add` calls dont get watched (@samcday). `removeAllListeners` on `close`.
-* 0.2.1 - Fix issue with invalid `added` events in current working dir.
-* 0.2.0 - Support and mark folders with `path.sep`. Add `forceWatchMethod` option. Support `renamed` events.
-* 0.1.6 - Recognize the `cwd` option properly
-* 0.1.5 - Catch “`too many open file`” errors
-* 0.1.4 - Really fix the race condition with 2 watches

-# Glob
-
-Match files using the patterns the shell uses, like stars and stuff.
-
-[![Build Status](https://travis-ci.org/isaacs/node-glob.svg?branch=master)](https://travis-ci.org/isaacs/node-glob/) [![Build Status](https://ci.appveyor.com/api/projects/status/kd7f3yftf7unxlsx?svg=true)](https://ci.appveyor.com/project/isaacs/node-glob) [![Coverage Status](https://coveralls.io/repos/isaacs/node-glob/badge.svg?branch=master&service=github)](https://coveralls.io/github/isaacs/node-glob?branch=master)
-
-This is a glob implementation in JavaScript.  It uses the `minimatch`
-library to do its matching.
-
-![](logo/glob.png)
-
-## Usage
-
-Install with npm
-
-```
-npm i glob
-```
-
-```javascript
-var glob = require("glob")
-
-// options is optional
-glob("**/*.js", options, function (er, files) {
-  // files is an array of filenames.
-  // If the `nonull` option is set, and nothing
-  // was found, then files is ["**/*.js"]
-  // er is an error object or null.
-})
-```
-
-## Glob Primer
-
-"Globs" are the patterns you type when you do stuff like `ls *.js` on
-the command line, or put `build/*` in a `.gitignore` file.
-
-Before parsing the path part patterns, braced sections are expanded
-into a set.  Braced sections start with `{` and end with `}`, with any
-number of comma-delimited sections within.  Braced sections may contain
-slash characters, so `a{/b/c,bcd}` would expand into `a/b/c` and `abcd`.
-
-The following characters have special magic meaning when used in a
-path portion:
-
-* `*` Matches 0 or more characters in a single path portion
-* `?` Matches 1 character
-* `[...]` Matches a range of characters, similar to a RegExp range.
-  If the first character of the range is `!` or `^` then it matches
-  any character not in the range.
-* `!(pattern|pattern|pattern)` Matches anything that does not match
-  any of the patterns provided.
-* `?(pattern|pattern|pattern)` Matches zero or one occurrence of the
-  patterns provided.
-* `+(pattern|pattern|pattern)` Matches one or more occurrences of the
-  patterns provided.
-* `*(a|b|c)` Matches zero or more occurrences of the patterns provided
-* `@(pattern|pat*|pat?erN)` Matches exactly one of the patterns
-  provided
-* `**` If a "globstar" is alone in a path portion, then it matches
-  zero or more directories and subdirectories searching for matches.
-  It does not crawl symlinked directories.
-
-### Dots
-
-If a file or directory path portion has a `.` as the first character,
-then it will not match any glob pattern unless that pattern's
-corresponding path part also has a `.` as its first character.
-
-For example, the pattern `a/.*/c` would match the file at `a/.b/c`.
-However the pattern `a/*/c` would not, because `*` does not start with
-a dot character.
-
-You can make glob treat dots as normal characters by setting
-`dot:true` in the options.
-
-### Basename Matching
-
-If you set `matchBase:true` in the options, and the pattern has no
-slashes in it, then it will seek for any file anywhere in the tree
-with a matching basename.  For example, `*.js` would match
-`test/simple/basic.js`.
-
-### Empty Sets
-
-If no matching files are found, then an empty array is returned.  This
-differs from the shell, where the pattern itself is returned.  For
-example:
-
-    $ echo a*s*d*f
-    a*s*d*f
-
-To get the bash-style behavior, set the `nonull:true` in the options.
-
-### See Also:
-
-* `man sh`
-* `man bash` (Search for "Pattern Matching")
-* `man 3 fnmatch`
-* `man 5 gitignore`

-
-## glob.hasMagic(pattern, [options])
-
-Returns `true` if there are any special characters in the pattern, and
-`false` otherwise.
-
-Note that the options affect the results.  If `noext:true` is set in
-the options object, then `+(a|b)` will not be considered a magic
-pattern.  If the pattern has a brace expansion, like `a/{b/c,x/y}`
-then that is considered magical, unless `nobrace:true` is set in the
-options.
-
-## glob(pattern, [options], cb)
-
-* `pattern` `{String}` Pattern to be matched
-* `options` `{Object}`
-* `cb` `{Function}`
-  * `err` `{Error | null}`
-  * `matches` `{Array<String>}` filenames found matching the pattern
-
-Perform an asynchronous glob search.
-
-## glob.sync(pattern, [options])
-
-* `pattern` `{String}` Pattern to be matched
-* `options` `{Object}`
-* return: `{Array<String>}` filenames found matching the pattern
-
-Perform a synchronous glob search.
-
-## Class: glob.Glob
-
-Create a Glob object by instantiating the `glob.Glob` class.
-
-```javascript
-var Glob = require("glob").Glob
-var mg = new Glob(pattern, options, cb)
-```
-
-It's an EventEmitter, and starts walking the filesystem to find matches
-immediately.
-
-### new glob.Glob(pattern, [options], [cb])
-
-* `pattern` `{String}` pattern to search for
-* `options` `{Object}`
-* `cb` `{Function}` Called when an error occurs, or matches are found
-  * `err` `{Error | null}`
-  * `matches` `{Array<String>}` filenames found matching the pattern
-
-Note that if the `sync` flag is set in the options, then matches will
-be immediately available on the `g.found` member.
-
-### Properties
-
-* `minimatch` The minimatch object that the glob uses.
-* `options` The options object passed in.
-* `aborted` Boolean which is set to true when calling `abort()`.  There
-  is no way at this time to continue a glob search after aborting, but
-  you can re-use the statCache to avoid having to duplicate syscalls.
-* `cache` Convenience object.  Each field has the following possible
-  values:
-  * `false` - Path does not exist
-  * `true` - Path exists
-  * `'FILE'` - Path exists, and is not a directory
-  * `'DIR'` - Path exists, and is a directory
-  * `[file, entries, ...]` - Path exists, is a directory, and the
-    array value is the results of `fs.readdir`
-* `statCache` Cache of `fs.stat` results, to prevent statting the same
-  path multiple times.
-* `symlinks` A record of which paths are symbolic links, which is
-  relevant in resolving `**` patterns.
-* `realpathCache` An optional object which is passed to `fs.realpath`
-  to minimize unnecessary syscalls.  It is stored on the instantiated
-  Glob object, and may be re-used.
-
-### Events
-
-* `end` When the matching is finished, this is emitted with all the
-  matches found.  If the `nonull` option is set, and no match was found,
-  then the `matches` list contains the original pattern.  The matches
-  are sorted, unless the `nosort` flag is set.
-* `match` Every time a match is found, this is emitted with the specific
-  thing that matched. It is not deduplicated or resolved to a realpath.
-* `error` Emitted when an unexpected error is encountered, or whenever
-  any fs error occurs if `options.strict` is set.
-* `abort` When `abort()` is called, this event is raised.
-
-### Methods
-
-* `pause` Temporarily stop the search
-* `resume` Resume the search
-* `abort` Stop the search forever
-
-### Options
-
-All the options that can be passed to Minimatch can also be passed to
-Glob to change pattern matching behavior.  Also, some have been added,
-or have glob-specific ramifications.
-
-All options are false by default, unless otherwise noted.
-
-All options are added to the Glob object, as well.
-
-If you are running many `glob` operations, you can pass a Glob object
-as the `options` argument to a subsequent operation to shortcut some
-`stat` and `readdir` calls.  At the very least, you may pass in shared
-`symlinks`, `statCache`, `realpathCache`, and `cache` options, so that
-parallel glob operations will be sped up by sharing information about
-the filesystem.
-
-* `cwd` The current working directory in which to search.  Defaults
-  to `process.cwd()`.
-* `root` The place where patterns starting with `/` will be mounted
-  onto.  Defaults to `path.resolve(options.cwd, "/")` (`/` on Unix
-  systems, and `C:\` or some such on Windows.)
-* `dot` Include `.dot` files in normal matches and `globstar` matches.
-  Note that an explicit dot in a portion of the pattern will always
-  match dot files.
-* `nomount` By default, a pattern starting with a forward-slash will be
-  "mounted" onto the root setting, so that a valid filesystem path is
-  returned.  Set this flag to disable that behavior.
-* `mark` Add a `/` character to directory matches.  Note that this
-  requires additional stat calls.
-* `nosort` Don't sort the results.
-* `stat` Set to true to stat *all* results.  This reduces performance
-  somewhat, and is completely unnecessary, unless `readdir` is presumed
-  to be an untrustworthy indicator of file existence.
-* `silent` When an unusual error is encountered when attempting to
-  read a directory, a warning will be printed to stderr.  Set the
-  `silent` option to true to suppress these warnings.
-* `strict` When an unusual error is encountered when attempting to
-  read a directory, the process will just continue on in search of
-  other matches.  Set the `strict` option to raise an error in these
-  cases.
-* `cache` See `cache` property above.  Pass in a previously generated
-  cache object to save some fs calls.
-* `statCache` A cache of results of filesystem information, to prevent
-  unnecessary stat calls.  While it should not normally be necessary
-  to set this, you may pass the statCache from one glob() call to the
-  options object of another, if you know that the filesystem will not
-  change between calls.  (See "Race Conditions" below.)
-* `symlinks` A cache of known symbolic links.  You may pass in a
-  previously generated `symlinks` object to save `lstat` calls when
-  resolving `**` matches.
-* `sync` DEPRECATED: use `glob.sync(pattern, opts)` instead.
-* `nounique` In some cases, brace-expanded patterns can result in the
-  same file showing up multiple times in the result set.  By default,
-  this implementation prevents duplicates in the result set.  Set this
-  flag to disable that behavior.
-* `nonull` Set to never return an empty set, instead returning a set
-  containing the pattern itself.  This is the default in glob(3).
-* `debug` Set to enable debug logging in minimatch and glob.
-* `nobrace` Do not expand `{a,b}` and `{1..3}` brace sets.
-* `noglobstar` Do not match `**` against multiple filenames.  (Ie,
-  treat it as a normal `*` instead.)
-* `noext` Do not match `+(a|b)` "extglob" patterns.
-* `nocase` Perform a case-insensitive match.  Note: on
-  case-insensitive filesystems, non-magic patterns will match by
-  default, since `stat` and `readdir` will not raise errors.
-* `matchBase` Perform a basename-only match if the pattern does not
-  contain any slash characters.  That is, `*.js` would be treated as
-  equivalent to `**/*.js`, matching all js files in all directories.
-* `nodir` Do not match directories, only files.  (Note: to match
-  *only* directories, simply put a `/` at the end of the pattern.)
-* `ignore` Add a pattern or an array of glob patterns to exclude matches.
-  Note: `ignore` patterns are *always* in `dot:true` mode, regardless
-  of any other settings.
-* `follow` Follow symlinked directories when expanding `**` patterns.
-  Note that this can result in a lot of duplicate references in the
-  presence of cyclic links.
-* `realpath` Set to true to call `fs.realpath` on all of the results.
-  In the case of a symlink that cannot be resolved, the full absolute
-  path to the matched entry is returned (though it will usually be a
-  broken symlink)
-* `absolute` Set to true to always receive absolute paths for matched
-  files.  Unlike `realpath`, this also affects the values returned in
-  the `match` event.
-
-## Comparisons to other fnmatch/glob implementations
-
-While strict compliance with the existing standards is a worthwhile
-goal, some discrepancies exist between node-glob and other
-implementations, and are intentional.
-
-The double-star character `**` is supported by default, unless the
-`noglobstar` flag is set.  This is supported in the manner of bsdglob
-and bash 4.3, where `**` only has special significance if it is the only
-thing in a path part.  That is, `a/**/b` will match `a/x/y/b`, but
-`a/**b` will not.
-
-Note that symlinked directories are not crawled as part of a `**`,
-though their contents may match against subsequent portions of the
-pattern.  This prevents infinite loops and duplicates and the like.
-
-If an escaped pattern has no matches, and the `nonull` flag is set,
-then glob returns the pattern as-provided, rather than
-interpreting the character escapes.  For example,
-`glob.match([], "\\*a\\?")` will return `"\\*a\\?"` rather than
-`"*a?"`.  This is akin to setting the `nullglob` option in bash, except
-that it does not resolve escaped pattern characters.
-
-If brace expansion is not disabled, then it is performed before any
-other interpretation of the glob pattern.  Thus, a pattern like
-`+(a|{b),c)}`, which would not be valid in bash or zsh, is expanded
-**first** into the set of `+(a|b)` and `+(a|c)`, and those patterns are
-checked for validity.  Since those two are valid, matching proceeds.
-
-### Comments and Negation
-
-Previously, this module let you mark a pattern as a "comment" if it
-started with a `#` character, or a "negated" pattern if it started
-with a `!` character.
-
-These options were deprecated in version 5, and removed in version 6.
-
-To specify things that should not match, use the `ignore` option.
-
-## Windows
-
-**Please only use forward-slashes in glob expressions.**
-
-Though windows uses either `/` or `\` as its path separator, only `/`
-characters are used by this glob implementation.  You must use
-forward-slashes **only** in glob expressions.  Back-slashes will always
-be interpreted as escape characters, not path separators.
-
-Results from absolute patterns such as `/foo/*` are mounted onto the
-root setting using `path.join`.  On windows, this will by default result
-in `/foo/*` matching `C:\foo\bar.txt`.
-
-## Race Conditions
-
-Glob searching, by its very nature, is susceptible to race conditions,
-since it relies on directory walking and such.
-
-As a result, it is possible that a file that exists when glob looks for
-it may have been deleted or modified by the time it returns the result.
-
-As part of its internal implementation, this program caches all stat
-and readdir calls that it makes, in order to cut down on system
-overhead.  However, this also makes it even more susceptible to races,
-especially if the cache or statCache objects are reused between glob
-calls.
-
-Users are thus advised not to use a glob result as a guarantee of
-filesystem state in the face of rapid changes.  For the vast majority
-of operations, this is never a problem.

-# globule [![Build Status: Linux](https://travis-ci.org/cowboy/node-globule.svg?branch=master)](https://travis-ci.org/cowboy/node-globule) [![Build Status: Windows](https://ci.appveyor.com/api/projects/status/i9fnc38q952r9nc0/branch/master?svg=true)](https://ci.appveyor.com/project/gruntjs/node-globule/branch/master)
-
-An easy-to-use wildcard globbing library.
-
-## Getting Started
-Install the module with: `npm install globule`
-
-```javascript
-var globule = require('globule');
-var filepaths = globule.find('**/*.js');
-```
-
-## Documentation
-
-### globule.find
-Returns a unique array of all file or directory paths that match the given globbing pattern(s). This method accepts either comma separated globbing patterns or an array of globbing patterns. Paths matching patterns that begin with `!` will be excluded from the returned array. Patterns are processed in order, so inclusion and exclusion order is significant. Patterns may be specified as function arguments or as a `src` property of the options object.
-
-```js
-globule.find(patterns [, patterns [, ...]] [, options])
-globule.find({src: patterns, /* other options */})
-```
-
-The `options` object supports all [glob][] library options, along with a few extras. These are the most commonly used:
-
-* `src` This property may be used instead of specifying patterns as function arguments.
-* `filter` Either a valid [fs.Stats method name](http://nodejs.org/docs/latest/api/fs.html#fs_class_fs_stats) or a function that will be passed the matched `src` filepath and `options` object as arguments. This function should return a `Boolean` value.
-* `nonull` Retain globbing patterns in result set even if they fail to match files.
-* `matchBase` Patterns without slashes will match just the basename part. Eg. this makes `*.js` work like `**/*.js`.
-* `srcBase` Patterns will be matched relative to the specified path instead of the current working directory. This is a synonym for `cwd`.
-* `prefixBase` Any specified `srcBase` will be prefixed to all returned filepaths.
-
-[glob]: https://github.com/isaacs/node-glob
-
-### globule.match
-Match one or more globbing patterns against one or more file paths. Returns a uniqued array of all file paths that match any of the specified globbing patterns. Both the `patterns` and `filepaths` arguments can be a single string or array of strings. Paths matching patterns that begin with `!` will be excluded from the returned array. Patterns are processed in order, so inclusion and exclusion order is significant.
-
-```js
-globule.match(patterns, filepaths [, options])
-```
-
-### globule.isMatch
-This method contains the same signature and logic as the `globule.match` method, but returns `true` if any files were matched, otherwise `false`.
-
-```js
-globule.isMatch(patterns, filepaths [, options])
-```
-
-### globule.mapping
-Given a set of source file paths, returns an array of src-dest file mapping objects. Both src and dest paths may be renamed, depending on the options specified. Patterns may be specified as function arguments or as a `src` property of the options object.
-
-```js
-globule.mapping(filepaths [, filepaths [, ...]]  [, options])
-globule.mapping({src: filepaths, /* other options */})
-```
-
-In addition to the options the `globule.find` method supports, the options object also supports these properties:
-
-* `srcBase` The directory from which patterns are matched. Any string specified as `srcBase` is effectively stripped from the beginning of all matched paths.
-* `destBase` The specified path is prefixed to all `dest` filepaths.
-* `ext` Remove anything after (and including) the first `.` in the destination path, then append this value.
-* `extDot` Change the behavior of `ext`, `"first"` and `"last"` will remove anything after the first or last `.` in the destination filename, respectively. Defaults to `"first"`.
-* `flatten` Remove the path component from all matched src files. The src file path is still joined to the specified destBase.
-* `rename` If specified, this function will be responsible for returning the final `dest` filepath. By default, it flattens paths (if specified), changes extensions (if specified) and joins the matched path to the `destBase`.
-
-### globule.findMapping
-This method is a convenience wrapper around the `globule.find` and `globule.mapping` methods.
-
-```js
-globule.findMapping(patterns [, options])
-```
-
-
-## Examples
-
-Given the files `foo/a.js` and `foo/b.js`:
-
-### srcBase and destBase
-
-```js
-globule.find("foo/*.js")
-// ["foo/a.js", "foo/b.js"]
-
-globule.find("*.js", {srcBase: "foo"})
-// ["a.js", "b.js"]
-
-globule.find({src: "*.js", srcBase: "foo", prefixBase: true})
-// ["foo/a.js", "foo/b.js"]
-```
-
-```js
-globule.findMapping("foo/*.js")
-// [{src: ["foo/a.js"], dest: "foo/a.js"}, {src: ["foo/b.js"], dest: "foo/b.js"}]
-
-globule.findMapping("foo/*.js", {destBase: "bar"})
-// [{src: ["foo/a.js"], dest: "bar/foo/a.js"}, {src: ["foo/b.js"], dest: "bar/foo/b.js"}]
-
-globule.findMapping({src: "*.js", srcBase: "foo", destBase: "bar"})
-// [{src: ["foo/a.js"], dest: "bar/a.js"}, {src: ["foo/b.js"], dest: "bar/b.js"}]
-```
-
-```js
-globule.mapping(["foo/a.js", "foo/b.js"])
-// [{src: ["foo/a.js"], dest: "foo/a.js"}, {src: ["foo/b.js"], dest: "foo/b.js"}]
-
-globule.mapping(["foo/a.js", "foo/b.js"], {destBase: "bar"})
-// [{src: ["foo/a.js"], dest: "bar/foo/a.js"}, {src: ["foo/b.js"], dest: "bar/foo/b.js"}]
-
-globule.mapping("foo/a.js", "foo/b.js", {destBase: "bar"})
-// [{src: ["foo/a.js"], dest: "bar/foo/a.js"}, {src: ["foo/b.js"], dest: "bar/foo/b.js"}]
-
-globule.mapping(["a.js", "b.js"], {srcBase: "foo", destBase: "bar"})
-// [{src: ["foo/a.js"], dest: "bar/a.js"}, {src: ["foo/b.js"], dest: "bar/b.js"}]
-
-globule.mapping({src: ["a.js", "b.js"], srcBase: "foo", destBase: "bar"})
-// [{src: ["foo/a.js"], dest: "bar/a.js"}, {src: ["foo/b.js"], dest: "bar/b.js"}]

-   * Creates a `lodash` object which wraps `value` to enable implicit method
-   * chain sequences. Methods that operate on and return arrays, collections,
-   * and functions can be chained together. Methods that retrieve a single value
-   * or may return a primitive value will automatically end the chain sequence
-   * and return the unwrapped value. Otherwise, the value must be unwrapped
-   * with `_#value`.
-   *
-   * Explicit chain sequences, which must be unwrapped with `_#value`, may be

-   *
-   * The execution of chained methods is lazy, that is, it's deferred until
-   * `_#value` is implicitly or explicitly called.
-   *
-   * Lazy evaluation allows several methods to support shortcut fusion.
-   * Shortcut fusion is an optimization to merge iteratee calls; this avoids
-   * the creation of intermediate arrays and can greatly reduce the number of
-   * iteratee executions. Sections of a chain sequence qualify for shortcut
-   * fusion if the section is applied to an array and iteratees accept only
-   * one argument. The heuristic for whether a section qualifies for shortcut
-   * fusion is subject to change.
-   *
-   * Chaining is supported in custom builds as long as the `_#value` method is
-   * directly or indirectly included in the build.
-   *
-   * In addition to lodash methods, wrappers have `Array` and `String` methods.
-   *
-   * The wrapper `Array` methods are:
-   * `concat`, `join`, `pop`, `push`, `shift`, `sort`, `splice`, and `unshift`
-   *
-   * The wrapper `String` methods are:

-   * `tail`, `take`, `takeRight`, `takeRightWhile`, `takeWhile`, and `toArray`
-   *

-/**
- * Creates a debounced function that delays invoking `func` until after `wait`
- * milliseconds have elapsed since the last time the debounced function was
- * invoked. The debounced function comes with a `cancel` method to cancel
- * delayed `func` invocations and a `flush` method to immediately invoke them.
- * Provide `options` to indicate whether `func` should be invoked on the
- * leading and/or trailing edge of the `wait` timeout. The `func` is invoked
- * with the last arguments provided to the debounced function. Subsequent
- * calls to the debounced function return the result of the last `func`
- * invocation.
- *
- * **Note:** If `leading` and `trailing` options are `true`, `func` is
- * invoked on the trailing edge of the timeout only if the debounced function
- * is invoked more than once during the `wait` timeout.
- *
- * If `wait` is `0` and `leading` is `false`, `func` invocation is deferred
- * until to the next tick, similar to `setTimeout` with a timeout of `0`.

-     * Creates a `lodash` object which wraps `value` to enable implicit method
-     * chain sequences. Methods that operate on and return arrays, collections,
-     * and functions can be chained together. Methods that retrieve a single value
-     * or may return a primitive value will automatically end the chain sequence
-     * and return the unwrapped value. Otherwise, the value must be unwrapped
-     * with `_#value`.
-     *
-     * Explicit chain sequences, which must be unwrapped with `_#value`, may be
-     * enabled using `_.chain`.
-     *
-     * The execution of chained methods is lazy, that is, it's deferred until
-     * `_#value` is implicitly or explicitly called.
-     *
-     * Lazy evaluation allows several methods to support shortcut fusion.
-     * Shortcut fusion is an optimization to merge iteratee calls; this avoids
-     * the creation of intermediate arrays and can greatly reduce the number of
-     * iteratee executions. Sections of a chain sequence qualify for shortcut
-     * fusion if the section is applied to an array and iteratees accept only
-     * one argument. The heuristic for whether a section qualifies for shortcut
-     * fusion is subject to change.
-     *
-     * Chaining is supported in custom builds as long as the `_#value` method is
-     * directly or indirectly included in the build.
-     *
-     * In addition to lodash methods, wrappers have `Array` and `String` methods.

-     *
-     * The wrapper `String` methods are:
-     * `replace` and `split`

-     * The wrapper methods that support shortcut fusion are:

-/**
- * Creates a `lodash` object which wraps `value` to enable implicit method
- * chain sequences. Methods that operate on and return arrays, collections,
- * and functions can be chained together. Methods that retrieve a single value
- * or may return a primitive value will automatically end the chain sequence
- * and return the unwrapped value. Otherwise, the value must be unwrapped
- * with `_#value`.
- *
- * Explicit chain sequences, which must be unwrapped with `_#value`, may be
- * enabled using `_.chain`.
- *
- * The execution of chained methods is lazy, that is, it's deferred until
- * `_#value` is implicitly or explicitly called.
- *
- * Lazy evaluation allows several methods to support shortcut fusion.
- * Shortcut fusion is an optimization to merge iteratee calls; this avoids
- * the creation of intermediate arrays and can greatly reduce the number of
- * iteratee executions. Sections of a chain sequence qualify for shortcut
- * fusion if the section is applied to an array and iteratees accept only
- * one argument. The heuristic for whether a section qualifies for shortcut
- * fusion is subject to change.
- *
- * Chaining is supported in custom builds as long as the `_#value` method is
- * directly or indirectly included in the build.
- *
- * In addition to lodash methods, wrappers have `Array` and `String` methods.
- *
- * The wrapper `Array` methods are:
- * `concat`, `join`, `pop`, `push`, `shift`, `sort`, `splice`, and `unshift`
- *
- * The wrapper `String` methods are:
- * `replace` and `split`
- *
- * The wrapper methods that support shortcut fusion are:

- * `findLast`, `head`, `initial`, `last`, `map`, `reject`, `reverse`, `slice`,
- * `tail`, `take`, `takeRight`, `takeRightWhile`, `takeWhile`, and `toArray`
- *
- * The chainable wrapper methods are:

-# minimatch
-
-A minimal matching utility.
-
-[![Build Status](https://secure.travis-ci.org/isaacs/minimatch.svg)](http://travis-ci.org/isaacs/minimatch)
-
-
-This is the matching library used internally by npm.
-
-It works by converting glob expressions into JavaScript `RegExp`
-objects.
-
-## Usage
-
-```javascript
-var minimatch = require("minimatch")
-
-minimatch("bar.foo", "*.foo") // true!
-minimatch("bar.foo", "*.bar") // false!
-minimatch("bar.foo", "*.+(bar|foo)", { debug: true }) // true, and noisy!
-```
-
-## Features
-
-Supports these glob features:
-
-* Brace Expansion
-* Extended glob matching
-* "Globstar" `**` matching
-
-See:
-
-* `man sh`
-* `man bash`
-* `man 3 fnmatch`
-* `man 5 gitignore`
-
-## Minimatch Class
-
-Create a minimatch object by instantiating the `minimatch.Minimatch` class.
-
-```javascript
-var Minimatch = require("minimatch").Minimatch
-var mm = new Minimatch(pattern, options)
-```
-
-### Properties
-
-* `pattern` The original pattern the minimatch object represents.
-* `options` The options supplied to the constructor.
-* `set` A 2-dimensional array of regexp or string expressions.
-  Each row in the
-  array corresponds to a brace-expanded pattern.  Each item in the row
-  corresponds to a single path-part.  For example, the pattern
-  `{a,b/c}/d` would expand to a set of patterns like:
-
-        [ [ a, d ]
-        , [ b, c, d ] ]
-
-    If a portion of the pattern doesn't have any "magic" in it
-    (that is, it's something like `"foo"` rather than `fo*o?`), then it
-    will be left as a string rather than converted to a regular
-    expression.
-
-* `regexp` Created by the `makeRe` method.  A single regular expression
-  expressing the entire pattern.  This is useful in cases where you wish
-  to use the pattern somewhat like `fnmatch(3)` with `FNM_PATH` enabled.
-* `negate` True if the pattern is negated.
-* `comment` True if the pattern is a comment.
-* `empty` True if the pattern is `""`.
-
-### Methods
-
-* `makeRe` Generate the `regexp` member if necessary, and return it.
-  Will return `false` if the pattern is invalid.
-* `match(fname)` Return true if the filename matches the pattern, or
-  false otherwise.
-* `matchOne(fileArray, patternArray, partial)` Take a `/`-split
-  filename, and match it against a single row in the `regExpSet`.  This
-  method is mainly for internal use, but is exposed so that it can be
-  used by a glob-walker that needs to avoid excessive filesystem calls.
-
-All other methods are internal, and will be called as necessary.
-
-### minimatch(path, pattern, options)
-
-Main export.  Tests a path against the pattern using the options.
-
-```javascript
-var isJS = minimatch(file, "*.js", { matchBase: true })
-```
-
-### minimatch.filter(pattern, options)
-
-Returns a function that tests its
-supplied argument, suitable for use with `Array.filter`.  Example:
-
-```javascript
-var javascripts = fileList.filter(minimatch.filter("*.js", {matchBase: true}))
-```
-
-### minimatch.match(list, pattern, options)
-
-Match against the list of
-files, in the style of fnmatch or glob.  If nothing is matched, and
-options.nonull is set, then return a list containing the pattern itself.
-
-```javascript
-var javascripts = minimatch.match(fileList, "*.js", {matchBase: true}))
-```
-
-### minimatch.makeRe(pattern, options)
-
-Make a regular expression object from the pattern.
-
-## Options
-
-All options are `false` by default.
-
-### debug
-
-Dump a ton of stuff to stderr.
-
-### nobrace
-
-Do not expand `{a,b}` and `{1..3}` brace sets.
-
-### noglobstar
-
-Disable `**` matching against multiple folder names.
-
-### dot
-
-Allow patterns to match filenames starting with a period, even if
-the pattern does not explicitly have a period in that spot.
-
-Note that by default, `a/**/b` will **not** match `a/.d/b`, unless `dot`
-is set.
-
-### noext
-
-Disable "extglob" style patterns like `+(a|b)`.
-
-### nocase
-
-Perform a case-insensitive match.
-
-### nonull
-
-When a match is not found by `minimatch.match`, return a list containing
-the pattern itself if this option is set.  When not set, an empty list
-is returned if there are no matches.
-
-### matchBase
-
-If set, then patterns without slashes will be matched
-against the basename of the path if it contains slashes.  For example,
-`a?b` would match the path `/xyz/123/acb`, but not `/xyz/acb/123`.
-
-### nocomment
-
-Suppress the behavior of treating `#` at the start of a pattern as a
-comment.
-
-### nonegate
-
-Suppress the behavior of treating a leading `!` character as negation.
-
-### flipNegate
-
-Returns from negate expressions the same as if they were not negated.
-(Ie, true on a hit, false on a miss.)
-
-
-## Comparisons to other fnmatch/glob implementations
-
-While strict compliance with the existing standards is a worthwhile
-goal, some discrepancies exist between minimatch and other
-implementations, and are intentional.
-
-If the pattern starts with a `!` character, then it is negated.  Set the
-`nonegate` flag to suppress this behavior, and treat leading `!`
-characters normally.  This is perhaps relevant if you wish to start the
-pattern with a negative extglob pattern like `!(a|B)`.  Multiple `!`
-characters at the start of a pattern will negate the pattern multiple
-times.
-
-If a pattern starts with `#`, then it is treated as a comment, and
-will not match anything.  Use `\#` to match a literal `#` at the
-start of a line, or set the `nocomment` flag to suppress this behavior.
-
-The double-star character `**` is supported by default, unless the
-`noglobstar` flag is set.  This is supported in the manner of bsdglob
-and bash 4.1, where `**` only has special significance if it is the only
-thing in a path part.  That is, `a/**/b` will match `a/x/y/b`, but
-`a/**b` will not.
-
-If an escaped pattern has no matches, and the `nonull` flag is set,
-then minimatch.match returns the pattern as-provided, rather than
-interpreting the character escapes.  For example,
-`minimatch.match([], "\\*a\\?")` will return `"\\*a\\?"` rather than
-`"*a?"`.  This is akin to setting the `nullglob` option in bash, except
-that it does not resolve escaped pattern characters.
-
-If brace expansion is not disabled, then it is performed before any
-other interpretation of the glob pattern.  Thus, a pattern like
-`+(a|{b),c)}`, which would not be valid in bash or zsh, is expanded
-**first** into the set of `+(a|b)` and `+(a|c)`, and those patterns are
-checked for validity.  Since those two are valid, matching proceeds.

-# Contributing to LibSass
-
-:+1::tada: First off, thanks for taking the time to contribute! :tada::+1:
-
-The following is a set of guidelines for contributing to LibSass, which is hosted in the [Sass Organization](https://github.com/sass) on GitHub.
-These are just guidelines, not rules, use your best judgment and feel free to propose changes to this document in a pull request.
-
-LibSass is a library that implements a [sass language][8] compiler. As such it does not directly interface with end users (frontend developers).
-For direct contributions to the LibSass code base you will need to have at least a rough idea of C++, we will not lie about that.
-But there are other ways to contribute to the progress of LibSass. All contributions are done via github pull requests.
-
-You can also contribute to the LibSass [documentation][9] or provide additional [spec tests][10] (and we will gladly point you in the
-direction for corners that lack test coverage). Foremost we rely on good and concise bug reports for issues the spec tests do not yet catch.
-
-## Precheck: My Sass isn't compiling
-- [ ] Check if you can reproduce the issue via [SourceMap Inspector][5] (updated regularly).
-- [ ] Validate official ruby sass compiler via [SassMeister][6] produces your expected result.
-- [ ] Search for similar issue in [LibSass][1] and [node-sass][2] (include closed tickets)
-- [ ] Optionally test your code directly with [sass][7] or [sassc][3] ([installer][4])
-
-## Precheck: My build/install fails
-- [ ] Problems with building or installing libsass should be directed to implementors first!
-- [ ] Except for issues directly verified via sassc or LibSass own build (make/autotools9
-
-## Craft a meaningfull error report
-- [ ] Include the version of libsass and the implementor (i.e. node-sass or sassc)
-- [ ] Include information about your operating system and environment (i.e. io.js)
-- [ ] Either create a self contained sample that shows your issue ...
-- [ ] ... or provide it as a fetchable (github preferred) archive/repo
-- [ ] ... and include a step by step list of command to get all dependencies
-- [ ] Make it clear if you use indented or/and scss syntax
-
-## My error is hiding in a big code base
-1. we do not have time to support your code base!
-2. to fix occuring issues we need precise bug reports
-3. the more precise you are, the faster we can help you
-4. lazy reports get overlooked even when exposing serious bugs
-5. it's not hard to do, it only takes time
-- [ ] Make sure you saved the current state (i.e. commit to git)
-- [ ] Start by uncommenting blocks in the initial source file
-- [ ] Check if the problem is still there after each edit
-- [ ] Repeat until the problem goes away
-- [ ] Inline imported files as you go along
-- [ ] Finished once you cannot remove more
-- [ ] The emphasis is on the word "repeat" ...
-
-## What makes a code test case
-
-Important is that someone else can get the test case up and running to reproduce it locally. For this
-we urge you to verify that your sample yields the expected result by testing it via [SassMeister][6]
-or directly via ruby sass or node-sass (or any other libsass implementor) before submitting your bug
-report. Once you verified all of the above, you may use the template below to file your bug report.

-
-
-[LibSass](https://github.com/sass/libsass "LibSass GitHub Project") is just a library!
-If you want to use LibSass to compile Sass, you need an implementer. Some
-implementations are only bindings into other programming languages. But most also
-ship with a command line interface (CLI) you can use directly. There is also
-[SassC](https://github.com/sass/sassc), which is the official lightweight
-CLI tool built by the same people as LibSass.
-
-### Excerpt of "sanctioned" implementations:
-
-- https://github.com/sass/node-sass (Node.js)
-- https://github.com/sass/perl-libsass (Perl)
-- https://github.com/sass/libsass-python (Python)
-- https://github.com/wellington/go-libsass (Go)
-- https://github.com/sass/sassc-ruby (Ruby)
-- https://github.com/sass/libsass-net (C#)
-- https://github.com/medialize/sass.js (JS)
-- https://github.com/bit3/jsass (Java)
-
-This list does not say anything about the quality of either the listed or not listed [implementations](docs/implementations.md)!  
-The authors of the listed projects above are just known to work regularly together with LibSass developers.
-
-About
------
-
-LibSass is a C++ port of the original Ruby Sass CSS compiler with a [C API](docs/api-doc.md).
-We coded LibSass with portability and efficiency in mind. You can expect LibSass to be a lot
-faster than Ruby Sass and on par or faster than the best alternative CSS compilers around.
-
-Developing
-----------
-
-As noted above, the LibSass repository does not contain any binaries or other way to execute
-LibSass. Therefore, you need an implementer to develop LibSass. Easiest is to start with
-the official [SassC](http://github.com/sass/sassc) CLI wrapper. It is *guaranteed* to compile
-with the latest code in LibSass master, since it is also used in the CI process. There is no
-limitation here, as you may use any other LibSass implementer to test your LibSass branch!
-
-Testing
--------
-
-Since LibSass is a pure library, tests are run through the [Sass-Spec](https://github.com/sass/sass-spec)
-project using the [SassC](http://github.com/sass/sassc) CLI wrapper. To run the tests against LibSass while
-developing, you can run `./script/spec`. This will clone SassC and Sass-Spec under the project folder and
-then run the Sass-Spec test suite. You may want to update the clones to ensure you have the latest version.
-Note that the scripts in the `./script` folder are mainly intended for our CI needs.
-
-Building
---------
-
-To build LibSass you need GCC 4.6+ or Clang/LLVM. If your OS is older, you may need to upgrade
-them first (or install clang as an alternative). On Windows, you need MinGW with GCC 4.6+ or VS 2013
-Update 4+. It is also possible to build LibSass with Clang/LLVM on Windows with various build chains
-and/or command line interpreters.
-
-See the [build docs for further instructions](docs/build.md)!
-
-Compatibility
--------------
-
-Current LibSass 3.4 should be compatible with Sass 3.4. Please refer to the [sass compatibility
-page](http://sass-compatibility.github.io/) for a more detailed comparison. But note that there
-are still a few incomplete edges which we are aware of. Otherwise LibSass has reached a good level
-of stability, thanks to our ever growing [Sass-Spec test suite](https://github.com/sass/sass-spec).
-
-About Sass
-----------
-
-Sass is a CSS pre-processor language to add on exciting, new, awesome features to CSS. Sass was
-the first language of its kind and by far the most mature and up to date codebase.
-
-Sass was originally conceived of by the co-creator of this library, Hampton Catlin ([@hcatlin]).
-Most of the language has been the result of years of work by Natalie Weizenbaum ([@nex3]) and
-Chris Eppstein ([@chriseppstein]).
-
-For more information about Sass itself, please visit http://sass-lang.com
-
-Initial development of LibSass by Aaron Leung and Hampton Catlin was supported by [Moovweb](http://www.moovweb.com).
-
-Licensing
----------
-
-Our [MIT license](LICENSE) is designed to be as simple and liberal as possible.

-Welcome to the LibSass documentation!
-
-## First Off
-LibSass is just a library. To run the code locally (i.e. to compile your stylesheets), you need an implementer. SassC (get it?) is an implementer written in C. There are a number of other implementations of LibSass - for example Node. We encourage you to write your own port - the whole point of LibSass is that we want to bring Sass to many other languages, not just Ruby!
-
-We're working hard on moving to full parity with Ruby Sass... learn more at the [The-LibSass-Compatibility-Plan](compatibility-plan.md)!
-
-### Implementing LibSass
-
-If you're interested in implementing LibSass in your own project see the [API Documentation](api-doc.md) which now includes implementing
-your own [Sass functions](api-function.md).  You may wish to [look at other implementations](implementations.md) for your language of choice.
-Or make your own!

-## Introduction
-
-LibSass wouldn't be much good without a way to interface with it. These
-interface documentations describe the various functions and data structures
-available to implementers. They are split up over three major components, which
-have all their own source files (plus some common functionality).
-
-- [Sass Context](api-context.md) - Trigger and handle the main Sass compilation
-- [Sass Value](api-value.md) - Exchange values and its format with LibSass
-- [Sass Function](api-function.md) - Get invoked by LibSass for function statments
-- [Sass Importer](api-importer.md) - Get invoked by LibSass for @import statments
-
-### Basic usage
-
-First you will need to include the header file!
-This will automatically load all other headers too!
-
-```C
-#include "sass/context.h"
-```
-
-## Basic C Example
-
-```C
-#include <stdio.h>
-#include "sass/context.h"
-
-int main() {
-  puts(libsass_version());
-  return 0;
-}
-```
-
-```bash
-gcc -Wall version.c -lsass -o version && ./version
-```
-

-- [Sample code for Sass Function](api-function-example.md)
-- [Sample code for Sass Importer](api-importer-example.md)
-
-## Compiling your code
-
-The most important is your sass file (or string of sass code). With this, you
-will want to start a LibSass compiler. Here is some pseudocode describing the
-process. The compiler has two different modes: direct input as a string with
-`Sass_Data_Context` or LibSass will do file reading for you by using
-`Sass_File_Context`. See the code for a list of options available
-[Sass_Options](https://github.com/sass/libsass/blob/36feef0/include/sass/interface.h#L18)
-
-**Building a file compiler**
-
-    context = sass_make_file_context("file.scss")
-    options = sass_file_context_get_options(context)
-    sass_option_set_precision(options, 1)
-    sass_option_set_source_comments(options, true)
-
-    sass_file_context_set_options(context, options)
-
-    compiler = sass_make_file_compiler(sass_context)
-    sass_compiler_parse(compiler)
-    sass_compiler_execute(compiler)
-
-    output = sass_context_get_output_string(context)
-    // Retrieve errors during compilation
-    error_status = sass_context_get_error_status(context)
-    json_error = sass_context_get_error_json(context)
-    // Release memory dedicated to the C compiler
-    sass_delete_compiler(compiler)
-
-**Building a data compiler**
-
-    context = sass_make_data_context("div { a { color: blue; } }")
-    options = sass_data_context_get_options(context)
-    sass_option_set_precision(options, 1)
-    sass_option_set_source_comments(options, true)
-
-    sass_data_context_set_options(context, options)
-
-    compiler = sass_make_data_compiler(context)
-    sass_compiler_parse(compiler)
-    sass_compiler_execute(compiler)
-
-    output = sass_context_get_output_string(context)
-    // div a { color: blue; }
-    // Retrieve errors during compilation
-    error_status = sass_context_get_error_status(context)
-    json_error = sass_context_get_error_json(context)
-    // Release memory dedicated to the C compiler
-    sass_delete_compiler(compiler)
-
-## Sass Context Internals
-
-Everything is stored in structs:
-
-```C
-struct Sass_Options;
-struct Sass_Context : Sass_Options;
-struct Sass_File_context : Sass_Context;
-struct Sass_Data_context : Sass_Context;
-```
-
-This mirrors very well how `libsass` uses these structures.
-
-- `Sass_Options` holds everything you feed in before the compilation. It also hosts
-`input_path` and `output_path` options, because they are used to generate/calculate
-relative links in source-maps. The `input_path` is shared with `Sass_File_Context`.
-- `Sass_Context` holds all the data returned by the compilation step.
-- `Sass_File_Context` is a specific implementation that requires no additional fields
-- `Sass_Data_Context` is a specific implementation that adds the `input_source` field
-
-Structs can be down-casted to access `context` or `options`!
-

-We keep memory around for as long as the main [context](api-context.md) object
-is not destroyed (`sass_delete_context`). LibSass will create copies of most
-inputs/options beside the main sass code. You need to allocate and fill that
-buffer before passing it to LibSass. You may also overtake memory management
-from libsass for certain return values (i.e. `sass_context_take_output_string`).
-
-```C
-// to allocate buffer to be filled
-void* sass_alloc_memory(size_t size);
-// to allocate a buffer from existing string
-char* sass_copy_c_string(const char* str);
-// to free overtaken memory when done
-void sass_free_memory(void* ptr);
-```
-
-## Miscellaneous API functions
-
-```C
-// Some convenient string helper function
-char* sass_string_unquote (const char* str);
-char* sass_string_quote (const char* str, const char quote_mark);
-
-// Get compiled libsass version
-const char* libsass_version(void);
-
-// Implemented sass language version
-// Hardcoded version 3.4 for time being
-const char* libsass_language_version(void);
-```
-
-## Common Pitfalls
-
-**input_path**
-
-The `input_path` is part of `Sass_Options`, but it also is the main option for
-`Sass_File_Context`. It is also used to generate relative file links in source-
-maps. Therefore it is pretty usefull to pass this information if you have a
-`Sass_Data_Context` and know the original path.
-
-**output_path**
-
-Be aware that `libsass` does not write the output file itself. This option
-merely exists to give `libsass` the proper information to generate links in
-source-maps. The file has to be written to the disk by the
-binding/implementation. If the `output_path` is omitted, `libsass` tries to
-extrapolate one from the `input_path` by replacing (or adding) the file ending
-with `.css`.
-
-## Error Codes
-
-The `error_code` is integer value which indicates the type of error that
-occurred inside the LibSass process. Following is the list of error codes along
-with the short description:
-
-* 1: normal errors like parsing or `eval` errors
-* 2: bad allocation error (memory error)
-* 3: "untranslated" C++ exception (`throw std::exception`)
-* 4: legacy string exceptions ( `throw const char*` or `std::string` )
-* 5: Some other unknown exception
-
-Although for the API consumer, error codes do not offer much value except
-indicating whether *any* error occurred during the compilation, it helps
-debugging the LibSass internal code paths.
-
-## Real-World Implementations
-
-The proof is in the pudding, so we have highlighted a few implementations that
-should be on par with the latest LibSass interface version. Some of them may not
-have all features implemented!
-
-1. [Perl Example](https://github.com/sass/perl-libsass/blob/master/lib/CSS/Sass.xs)
-2. [Go Example](https://godoc.org/github.com/wellington/go-libsass#example-Compiler--Stdin)
-3. [Node Example](https://github.com/sass/node-sass/blob/master/src/binding.cpp)
-
-## ABI forward compatibility
-
-We use a functional API to make dynamic linking more robust and future
-compatible. The API is not yet 100% stable, so we do not yet guarantee
-[ABI](https://gcc.gnu.org/onlinedocs/libstdc++/manual/abi.html) forward
-compatibility.
-
-## Plugins (experimental)
-
-LibSass can load plugins from directories. Just define `plugin_path` on context
-options to load all plugins from the directories. To implement plugins, please
-consult the following example implementations.

-Sass functions are used to define new custom functions callable by Sass code. They are also used to overload debug or error statements. You can also define a fallback function, which is called for every unknown function found in the Sass code. Functions get passed zero or more `Sass_Values` (a `Sass_List` value) and they must also return a `Sass_Value`. Return a `Sass_Error` if you want to signal an error.
-
-## Special signatures
-
-- `*` - Fallback implementation
-- `@warn` - Overload warn statements
-- `@error` - Overload error statements
-- `@debug` - Overload debug statements
-
-Note: The fallback implementation will be given the name of the called function as the first argument, before all the original function arguments. These features are pretty new and should be considered experimental.

-By using custom importers, Sass stylesheets can be implemented in any possible way, such as by being loaded via a remote server. Please note: this feature is experimental and is implemented differently than importers in Ruby Sass. Imports must be relative to the parent import context and therefore we need to pass this information to the importer callback. This is currently done by passing the complete import string/path of the previous import context.
-
-## Return Imports
-
-You actually have to return a list of imports, since some importers may want to import multiple files from one import statement (ie. a glob/star importer).  The memory you pass with source and srcmap is taken over by LibSass and freed automatically when the import is done. You are also allowed to return `0` instead of a list, which will tell LibSass to handle the import by itself (as if no custom importer was in use).
-
-```C
-Sass_Import_Entry* rv = sass_make_import_list(1);
-rv[0] = sass_make_import(rel, abs, source, srcmap);
-```
-
-Every import will then be included in LibSass. You are allowed to only return a file path without any loaded source. This way you can ie. implement rewrite rules for import paths and leave the loading part for LibSass.
-
-Please note that LibSass doesn't use the srcmap parameter yet. It has been added to not deprecate the C-API once support has been implemented. It will be used to re-map the actual sourcemap with the provided ones.

-`Sass_Values` are used to pass values and their types between the implementer
-and LibSass. Sass knows various different value types (including nested arrays
-and hash-maps). If you implement a binding to another programming language, you
-have to find a way to [marshal][1] (convert) `Sass_Values` between the target
-language and C. `Sass_Values` are currently only used by custom functions, but
-it should also be possible to use them without a compiler context.
-
-[1]: https://en.wikipedia.org/wiki/Marshalling_%28computer_science%29
-
-### Basic Usage
-
-```C
-#include "sass/values.h"
-```
-
-```C
-// Type for Sass values
-enum Sass_Tag {
-  SASS_BOOLEAN,
-  SASS_NUMBER,
-  SASS_COLOR,
-  SASS_STRING,
-  SASS_LIST,
-  SASS_MAP,
-  SASS_NULL,
-  SASS_ERROR,
-  SASS_WARNING
-};
-
-// Tags for denoting Sass list separators
-enum Sass_Separator {
-  SASS_COMMA,
-  SASS_SPACE,
-  // only used internally to represent a hash map before evaluation
-  // otherwise we would be too early to check for duplicate keys
-  SASS_HASH
-};
-
-// Value Operators
-enum Sass_OP {
-  AND, OR,                   // logical connectives
-  EQ, NEQ, GT, GTE, LT, LTE, // arithmetic relations
-  ADD, SUB, MUL, DIV, MOD,   // arithmetic functions
-  NUM_OPS                    // so we know how big to make the op table
-};
-```

-We support builds via MingGW and via Visual Studio Community 2013.
-Both should be considered experimental (MinGW was better tested)!
-
-## Building via MingGW (makefiles)
-
-First grab the latest [MinGW for windows][1] installer. Once it is installed, you can click on continue or open the Installation Manager via `bin\mingw-get.exe`.
-
-You need to have the following components installed:
-![Visualization of components installed in the interface](https://cloud.githubusercontent.com/assets/282293/5525466/947bf396-89e6-11e4-841d-4aa916f14de1.png)
-
-Next we need to install [git for windows][2]. You probably want to check the option to add it to the global path, but you do not need to install the unix tools.
-
-If you want to run the spec test-suite you also need [ruby][3] and a few gems available. Grab the [latest installer][3] and make sure to add it the global path. Then install the missing gems:
-
-```bash
-gem install minitest
-```
-
-### Mount the mingw root directory
-
-As mentioned in the [MinGW Getting Started](http://www.mingw.org/wiki/Getting_Started#toc5) guide, you should edit `C:\MinGW\msys\1.0\etc\fstab` to contain the following line:
-
-```
-C:\MinGW   /mingw
-```
-
-### Starting a "MingGW" console
-
-Create a batch file with this content:
-```bat
-@echo off
-set PATH=C:\MinGW\bin;%PATH%
-REM only needed if not already available
-set PATH=%PROGRAMFILES%\git\bin;%PATH%
-REM C:\MinGW\msys\1.0\msys.bat
-cmd
-```
-
-Execute it and make sure these commands can be called: `git`, `mingw32-make`, `rm` and `gcc`! Once this is all set, you should be ready to compile `libsass`!
-
-### Get the sources
-
-```bash
-# using git is preferred
-git clone https://github.com/sass/libsass.git
-# only needed for sassc and/or testsuite
-git clone https://github.com/sass/sassc.git libsass/sassc
-git clone https://github.com/sass/sass-spec.git libsass/sass-spec
-```
-
-### Decide for static or shared library
-
-`libsass` can be built and linked as a `static` or as a `shared` library. The default is `static`. To change it you can set the `BUILD` environment variable:
-
-```bat
-set BUILD="shared"
-```
-
-### Compile the library
-```bash
-mingw32-make -C libsass
-```
-
-### Results can be found in
-```bash
-$ ls libsass/lib
-libsass.a  libsass.dll  libsass.so
-```
-
-### Run the spec test-suite
-```bash
-mingw32-make -C libsass test_build
-```
-
-## Building via MingGW 64bit (makefiles)
-Building libass to dll on window 64bit.
-
-+ downloads  [MinGW64 for windows7 64bit](http://sourceforge.net/projects/mingw-w64/files/Toolchains%20targetting%20Win64/Personal%20Builds/mingw-builds/4.9.2/threads-win32/seh/x86_64-4.9.2-release-win32-seh-rt_v3-rev0.7z/download) , and unzip to "C:\mingw64".
-
-+ Create a batch file with this content:
-
-```bat
-@echo off
-set PATH=C:\mingw64\bin;%PATH%
-set CC=gcc
-REM only needed if not already available
-set PATH=%PROGRAMFILES%\Git\bin;%PATH%
-REM C:\MinGW\msys\1.0\msys.bat
-cmd
-```
-
-+ By default , mingw64 dll will depends on "​m​i​n​g​w​m​1​0​.​d​l​l​、​ ​l​i​b​g​c​c​_​s​_​d​w​2​-​1​.​d​l​l​" , we can modify Makefile to fix this:(add "-static")
-
-``` bash
-lib/libsass.dll: $(COBJECTS) $(OBJECTS) $(RCOBJECTS)
-	$(MKDIR) lib
-	$(CXX) -shared $(LDFLAGS) -o $@ $(COBJECTS) $(OBJECTS) $(RCOBJECTS) $(LDLIBS) -s -static -Wl,--subsystem,windows,--out-implib,lib/libsass.a
-```
-
-+ Compile the library
-
-```bash
-mingw32-make -C libsass
-```
-
-By the way , if you are using java jna , [JNAerator](http://jnaerator.googlecode.com/) is a good tool.
-
-## Building via Visual Studio Community 2013
-
-Open a Visual Studio 2013 command prompt:
-- `VS2013 x86 Native Tools Command Prompt`
-
-Note: When I installed the community edition, I only got the 2012 command prompts. I copied them from the Startmenu to the Desktop and adjusted the paths from `Visual Studio 11.0` to `Visual Studio 12.0`. Since `libsass` uses some `C++11` features, you need at least a MSVC 2013 compiler (v120).
-
-### Get the source
-```bash
-# using git is preferred
-git clone https://github.com/sass/libsass.git
-git clone https://github.com/sass/sassc.git libsass/sassc
-# only needed if you want to run the testsuite
-git clone https://github.com/sass/sass-spec.git libsass/sass-spec
-```
-
-### Compile sassc
-
-Sometimes `msbuild` seems not available from the command prompt. Just search for it and add it to the global path. It seems to be included in the .net folders too.
-
-```bat
-cd libsass
-REM set PATH=%PATH%;%PROGRAMFILES%\MSBuild\12.0\Bin
-msbuild /m:4 /p:Configuration=Release win\libsass.sln
-REM running the spec test-suite manually (needs ruby and minitest gem)
-ruby sass-spec\sass-spec.rb -V 3.5 -c win\bin\sassc.exe -s --impl libsass sass-spec/spec
-cd ..

-This page is mostly intended for people that want to build a system library that gets distributed via RPMs or other means. This is currently in a experimental phase, as we currently do not really guarantee any ABI forward compatibility. The C API was rewritten to make this possible in the future, but we want to wait some more time till we can call this final and stable.
-
-Building via autotools
---
-
-You want to build a system library only via autotools, since it will create the proper `libtool` files to make it loadable on multiple systems. We hope this works correctly, but nobody of the `libsass` core team has much knowledge in this area. Therefore we are open for comments or improvements by people that have more experience in that matter (like package maintainers from various linux distributions).

-git clone https://github.com/sass/sass-spec.git libsass/sass-spec
-```
-
-### Prerequisites
-
-In order to run autotools you need a few tools installed on your system.
-```bash
-yum install automake libtool # RedHat Linux
-emerge -a automake libtool # Gentoo Linux
-pkgin install automake libtool # SmartOS
-```
-
-
-### Create configure script
-```bash
-cd libsass
-autoreconf --force --install
-cd ..
-```
-
-### Create custom makefiles
-```bash
-cd libsass
-./configure \
-  --disable-tests \
-  --disable-shared \
-  --prefix=/usr
-cd ..
-```
-
-### Build the library
-```bash
-make -C libsass -j5
-```
-
-### Install the library
-The library will be installed to the location given as `prefix` to `configure`. This is standard behavior for autotools and not `libsass` specific.
-```bash
-make -C libsass -j5 install
-```
-
-### Configure options
-The `configure` script is created by autotools. To get an overview of available options you can call `./configure --help`. When you execute this script, it will create specific makefiles, which you then use via the regular make command.
-
-There are some `libsass` specific options:
-
-```
-Optional Features:
-  --enable-tests              enable testing the build
-  --enable-coverage           enable coverage report for test suite
-  --enable-shared             build shared libraries [default=yes]
-  --enable-static             build static libraries [default=yes]
-
-Optional Packages:
-  --with-sassc-dir=<dir>      specify directory of sassc sources for
-                              testing (default: sassc)
-  --with-sass-spec-dir=<dir>  specify directory of sass-spec for testing
-                              (default: sass-spec)
-```
-
-### Build sassc and run spec test-suite
-
-```bash
-cd libsass
-autoreconf --force --install
-./configure \
-  --enable-tests \
-  --enable-shared \
-  --prefix=/usr
-make -j5 test_build
-cd ..

-## Building LibSass with MingGW (makefiles)
-
-First grab the latest [MinGW for windows][1] installer. Once it is installed, you can click on continue or open the Installation Manager via `bin\mingw-get.exe`.
-
-You need to have the following components installed:
-![](https://cloud.githubusercontent.com/assets/282293/5525466/947bf396-89e6-11e4-841d-4aa916f14de1.png)
-
-Next we need to install [git for windows][2]. You probably want to check the option to add it to the global path, but you do not need to install the unix tools.
-
-If you want to run the spec test-suite you also need [ruby][3] and a few gems available. Grab the [latest installer][3] and make sure to add it the global path. Then install the missing gems:
-
-```bash
-gem install minitest
-```
-
-### Mount the mingw root directory
-
-As mentioned in the [MinGW Getting Started](http://www.mingw.org/wiki/Getting_Started#toc5) guide, you should edit `C:\MinGW\msys\1.0\etc\fstab` to contain the following line:
-
-```
-C:\MinGW   /mingw
-```
-
-### Starting a "MingGW" console
-
-Create a batch file with this content:
-```bat
-@echo off
-set PATH=C:\MinGW\bin;%PATH%
-REM only needed if not already available
-set PATH=%PROGRAMFILES%\git\bin;%PATH%
-REM C:\MinGW\msys\1.0\msys.bat
-cmd
-```
-
-Execute it and make sure these commands can be called: `git`, `mingw32-make`, `rm` and `gcc`! Once this is all set, you should be ready to compile `libsass`!
-
-### Get the sources
-
-```bash
-# using git is preferred
-git clone https://github.com/sass/libsass.git
-# only needed for sassc and/or testsuite
-git clone https://github.com/sass/sassc.git libsass/sassc
-git clone https://github.com/sass/sass-spec.git libsass/sass-spec
-```
-
-### Decide for static or shared library
-
-`libsass` can be built and linked as a `static` or as a `shared` library. The default is `static`. To change it you can set the `BUILD` environment variable:
-
-```bat
-set BUILD="shared"
-```
-
-### Compile the library
-```bash
-mingw32-make -C libsass
-```
-
-### Results can be found in
-```bash
-$ ls libsass/lib
-libsass.a  libsass.dll  libsass.so
-```
-
-### Run the spec test-suite
-```bash
-mingw32-make -C libsass test_build
-```
-
-## Building via MingGW 64bit (makefiles)
-Building libass to dll on window 64bit.
-
-Download [MinGW64 for windows7 64bit](http://sourceforge.net/projects/mingw-w64/files/Toolchains%20targetting%20Win64/Personal%20Builds/mingw-builds/4.9.2/threads-win32/seh/x86_64-4.9.2-release-win32-seh-rt_v3-rev0.7z/download) and unzip to "C:\mingw64".
-
-Create a batch file with this content:
-
-```bat
-@echo off
-set PATH=C:\mingw64\bin;%PATH%
-set CC=gcc
-REM only needed if not already available
-set PATH=%PROGRAMFILES%\Git\bin;%PATH%
-REM C:\MinGW\msys\1.0\msys.bat
-cmd
-```
-
-By default, mingw64 dll will depends on "​m​i​n​g​w​m​1​0​.​d​l​l​、​ ​l​i​b​g​c​c​_​s​_​d​w​2​-​1​.​d​l​l​", we can modify Makefile to fix this:(add "-static")
-
-``` bash
-lib/libsass.dll: $(COBJECTS) $(OBJECTS) $(RCOBJECTS)
-	$(MKDIR) lib
-	$(CXX) -shared $(LDFLAGS) -o $@ $(COBJECTS) $(OBJECTS) $(RCOBJECTS) $(LDLIBS) -s -static -Wl,--subsystem,windows,--out-implib,lib/libsass.a
-```
-
-Compile the library
-
-```bash
-mingw32-make -C libsass
-```
-
-By the way, if you are using java jna, [JNAerator](http://jnaerator.googlecode.com/) is a good tool.

-## Building LibSass with Visual Studio
-
-### Requirements:
-
-The minimum requirement to build LibSass with Visual Studio is "Visual Studio 2013 Express for Desktop".
-
-Additionally, it is recommended to have `git` installed and available in `PATH`, so to deduce the `libsass` version information. For instance, if GitHub for Windows (https://windows.github.com/) is installed, the `PATH` will have an entry resembling: `X:\Users\<YOUR_NAME>\AppData\Local\GitHub\PortableGit_<SOME_GUID>\cmd\` (where `X` is the drive letter of system drive). If `git` is not available, inquiring the LibSass version will result in `[NA]`.
-
-### Build Steps:
-
-#### From Visual Studio:
-
-On opening the `win\libsass.sln` solution and build (Ctrl+Shift+B) to build `libsass.dll`.
-
-To Build LibSass as a static Library, it is recommended to set an environment variable `LIBSASS_STATIC_LIB` before launching the project:
-
-```cmd
-cd path\to\libsass
-SET LIBSASS_STATIC_LIB=1
-::
-:: or in PowerShell:
-:: $env:LIBSASS_STATIC_LIB=1
-::
-win\libsass.sln
-```
-
-Visual Studio will form the filtered source tree as shown below:
-
-![image](https://cloud.githubusercontent.com/assets/3840695/9298985/aae9e072-44bf-11e5-89eb-e7995c098085.png)
-
-`Header Files` contains the .h and .hpp files, while `Source Files` covers `.c` and `.cpp`. The other used headers/sources will appear under `External Dependencies`.
-
-If there is a LibSass code file appearing under External Dependencies, it can be changed by altering the `win\libsass.vcxproj.filters` file or dragging in Solution Explorer.
-
-#### From Command Prompt:
-
-Notice that in the following commands:
-
-* If the platform is 32-bit Windows, replace `ProgramFiles(x86)` with `ProgramFiles`.
-* To build with Visual Studio 2015, replace `12.0` with `14.0` in the aforementioned command.
-
-Open a command prompt:
-
-To build dynamic/shared library (`libsass.dll`):
-
-```cmd
-:: debug build:
-"%ProgramFiles(x86)%\MSBuild\12.0\Bin\MSBuild" win\libsass.sln
-
-:: release build:
-"%ProgramFiles(x86)%\MSBuild\12.0\Bin\MSBuild" win\libsass.sln ^
-/p:Configuration=Release
-```
-
-To build static library (`libsass.lib`):
-
-```cmd
-:: debug build:
-"%ProgramFiles(x86)%\MSBuild\12.0\Bin\MSBuild" win\libsass.sln ^
-/p:LIBSASS_STATIC_LIB=1
-
-:: release build:
-"%ProgramFiles(x86)%\MSBuild\12.0\Bin\MSBuild" win\libsass.sln ^
-/p:LIBSASS_STATIC_LIB=1 /p:Configuration=Release
-```
-
-#### From PowerShell:
-
-To build dynamic/shared library (`libsass.dll`):
-
-```powershell
-# debug build:
-&"${env:ProgramFiles(x86)}\MSBuild\12.0\Bin\MSBuild" win\libsass.sln
-
-# release build:
-&"${env:ProgramFiles(x86)}\MSBuild\12.0\Bin\MSBuild" win\libsass.sln `
-/p:Configuration=Release
-```
-
-To build static library (`libsass.lib`):
-
-```powershell
-# build:
-&"${env:ProgramFiles(x86)}\MSBuild\12.0\Bin\MSBuild" win\libsass.sln `
-/p:LIBSASS_STATIC_LIB=1
-
-# release build:
-&"${env:ProgramFiles(x86)}\MSBuild\12.0\Bin\MSBuild" win\libsass.sln `

-`libsass` is only a library and does not do much on its own. You need an implementation that you can use from the [command line][6]. Or some [bindings|Implementations][9] to use it within your favorite programming language. You should be able to get [`sassc`][6] running by following the instructions in this guide.
-
-Before starting, see [setup dev environment](setup-environment.md).
-
-Building on different Operating Systems
---
-
-We try to keep the code as OS independent and standard compliant as possible. Reading files from the file-system has some OS depending code, but will ultimately fall back to a posix compatible implementation. We do use some `C++11` features, but are so far only committed to use `unordered_map`. This means you will need a pretty recent compiler on most systems (gcc 4.5 seems to be the minimum).
-
-### Building on Linux (and other *nix flavors)
-
-Linux is the main target for `libsass` and we support two ways to build `libsass` here. The old plain makefiles should still work on most systems (including MinGW), while the autotools build is preferred if you want to create a [system library] (experimental).
-
-- [Building with makefiles][1]
-- [Building with autotools][2]
-
-### Building on Windows (experimental)
-
-Windows build support was added very recently and should be considered experimental. Credits go to @darrenkopp and @am11 for their work on getting `libsass` and `sassc` to compile with visual studio!
-
-- [Building with MinGW][3]
-- [Building with Visual Studio][11]
-
-### Building on Max OS X (untested)
-
-Works the same as on linux, but you can also install LibSass via `homebrew`.
-
-- [Building on Mac OS X][10]
-
-### Building a system library (experimental)
-
-Since `libsass` is a library, it makes sense to install it as a shared library on your system. On linux this means creating a `.so` library via autotools. This should work pretty well already, but we are not yet committed to keep the ABI 100% stable. This should be the case once we increase the version number for the library to 1.0.0 or higher. On Windows you should be able get a `dll` by creating a shared build with MinGW. There is currently no target in the MSVC project files to do this.
-
-- [Building shared system library][4]
-
-Compiling with clang instead of gcc
---
-
-To use clang you just need to set the appropriate environment variables:
-
-```bash
-export CC=/usr/bin/clang
-export CXX=/usr/bin/clang++
-```
-
-Running the spec test-suite
---
-
-We constantly and automatically test `libsass` against the official [spec test-suite][5]. To do this we need to have a test-runner (which is written in ruby) and a command-line tool ([`sassc`][6]) to run the tests. Therefore we need to additionally compile `sassc`. To do this, the build files of all three projects need to work together. This may not have the same quality for all build flavors. You definitely need to have ruby (2.1?) installed (version 1.9 seems to cause problems at least on windows). You also need some gems installed:
-
-```bash
-ruby -v
-gem install minitest
-# should be optional
-gem install minitap
-```
-
-Including the LibSass version
---
-
-There is a function in `libsass` to query the current version. This has to be defined at compile time. We use a C macro for this, which can be defined by calling `g++ -DLIBSASS_VERSION="\"x.y.z.\""`. The two quotes are necessary, since it needs to end up as a valid C string. Normally you do not need to do anything if you use the makefiles or autotools. They will try to fetch the version via git directly. If you only have the sources without the git repo, you can pass the version as an environment variable to `make` or `configure`:
-
-```
-export LIBSASS_VERSION="x.y.z."
-```
-
-Continuous Integration
---
-
-We use two CI services to automatically test all commits against the latest [spec test-suite][5].

-Why not using CMake?
---
-
-There were some efforts to get `libsass` to compile with CMake, which should make it easier to create build files for linux and windows. Unfortunately this was not completed. But we are certainly open for PRs!

-This document is to serve as a living, changing plan for getting LibSass caught up with Ruby Sass.
-
-_Note: an "s" preceeding a version number is specifying a Ruby Sass version. Without an s, it's a version of LibSass._
-
-# Goal
-**Our goal is to reach full s3.4 compatibility as soon as possible. LibSass version 3.4 will behave just like Ruby Sass 3.4**
-
-I highlight the goal, because there are some things that are *not* currently priorities. To be clear, they WILL be priorities, but they are not at the moment:
-
-* Performance Improvements
-* Extensibility
-
-The overriding goal is correctness.
-
-## Verifying Correctness
-LibSass uses the spec for its testing. The spec was originally based off s3.2 tests. Many things have changed in Ruby Sass since then and some of the tests need to be updated and changed in order to get them to match both LibSass and Ruby Sass.
-
-Until this project is complete, the spec will be primarily a place to test LibSass. By the time LibSass reaches 3.4, it is our goal that sass-spec will be fully usable as an official testing source for ALL implementations of Sass.
-
-## Version Naming
-Until LibSass reaches parity with Ruby Sass, we will be aggressively bumping versions, and LibSass 3.4 will be the peer to Ruby Sass 3.4 in every way.
-
-# Release Plan
-
-## 3.0
-The goal of 3.0 is to introduce some of the most demanded features for LibSass. That is, we are focusing on issues and features that have kept adoption down. This is a mongrel release wrt which version of Sass it's targeting. It's often a mixture of 3.2 / 3.3 / 3.4 behaviours. This is not ideal, but it's favourable to not existing. Targeting 3.4 strictly during this release would mean we never actually release.
-
-# 3.1
-The goal of 3.1 is to update all the passing specs to agree with 3.4. This will not be a complete representation of s3.4 (aka, there will me missing features), but the goal is to change existing features and implemented features to match 3.4 behaviour.
-
-By the end of this, the sass-spec must pass against 3.4.
-
-Major issues:
-* Variable Scoping
-* Color Handling
-* Precision
-
-# 3.2
-This version will focus on edge case fixes. There are a LOT of edge cases in the _todo_ tests and this is the release where we hunt those down like dogs (not that we want to hurt dogs, it's just a figure of speech in English).
-
-# 3.3
-Dress rehearsal. When we are 99% sure that we've fixed the main issues keeping us from saying we are compliant in s3.4 behaviour.
-
-# 3.4
-Compass Compatibility. We need to be able to work with Compass and all the other libraries out there. At this point, we are calling LibSass "mature"
-
-# Beyond 3.4
-Obviously, there is matching Sass 3.5 behaviour. But, beyond that, we'll want to focus on performance, stability, and error handling. These can always be improved upon and are the life's work of an open source project. We'll have to work closely with Sass in the future.

-First of all, welcome! Thanks for even reading this page. If you're here, you're probably wondering what you can do to help make the LibSass project even more awesome. And, even having that feeling means you are awesome!
-
-## I'm a programmer
-
-Awesome! We need your help. The best thing to do is go find issues that are tagged with both "bug" and "test written". We do spec driven development here and these issues have a test that's written already in the sass-spec project. Go find the test by going to sass-spec/spec/LibSass-todo-issues/issue_XXX/ where XXX is the issue number. Write the code, and compile, and then issue a pull request referencing the issue. We'll quickly verify it and get it merged in!
-
-To get your dev environment setup, check out our article on [Setup-Dev-Environment](setup-environment.md).
-
-## I'm not a backend programmer
-
-COOL! We also need your help. Doing [Issue-Triage](triage.md) is a big deal and something we need constant help with. That means helping to verify issues, write tests for them, and make sure they are getting fixed. It's being part of the smiling face of the project.
-
-Also, we need help with the Sass-Spec project itself. Just people to organize, refactor, and understand the tests in there.
-
-## I don't know what a computer is?

-# Developer Documentation
-
-Custom functions are internally represented by `struct Sass_C_Function_Descriptor`.
-
-## Sass_C_Function_Descriptor
-
-```C
-struct Sass_C_Function_Descriptor {
-  const char*      signature;
-  Sass_C_Function  function;
-  void*            cookie;
-};
-```
-
-- `signature`: The function declaration, like `foo($bar, $baz:1)`
-- `function`:  Reference to the C function callback
-- `cookie`:    any pointer you want to attach
-
-### signature
-
-The signature defines how the function can be invoked. It also declares which arguments are required and which are optional.  Required arguments will be enforced by LibSass and a Sass error is thrown in the event a call as missing an argument. Optional arguments only need to be present when you want to overwrite the default value.
-
-    foo($bar, $baz: 2)
-
-In this example, `$bar` is required and will error if not passed. `$baz` is optional and the default value of it is 2. A call like `foo(10)` is therefore equal to `foo(10, 2)`, while `foo()` will produce an error.
-
-### function
-
-The callback function needs to be of the following form:
-
-```C
-union Sass_Value* call_sass_function(
-    const union Sass_Value* s_args,
-    void*                   cookie
-) {
-  return sass_clone_value(s_args);
-}
-```
-
-### cookie
-
-The cookie can hold any pointer you want. In the `perl-libsass` implementation it holds the structure with the reference of the actual registered callback into the perl interpreter. Before that call `perl-libsass` will convert all `Sass_Values` to corresponding perl data types (so they can be used natively inside the perl interpretor). The callback can also return a `Sass_Value`. In `perl-libsass` the actual function returns a perl value, which has to be converted before `libsass` can work with it again!
-
-## Sass_Values
-
-```C
-// allocate memory (copies passed strings)
-union Sass_Value* sass_make_null    (void);
-union Sass_Value* sass_make_boolean (bool val);
-union Sass_Value* sass_make_string  (const char* val);
-union Sass_Value* sass_make_qstring (const char* val);
-union Sass_Value* sass_make_number  (double val, const char* unit);
-union Sass_Value* sass_make_color   (double r, double g, double b, double a);
-union Sass_Value* sass_make_list    (size_t len, enum Sass_Separator sep, bool is_bracketed);
-union Sass_Value* sass_make_map     (size_t len);
-union Sass_Value* sass_make_error   (const char* msg);
-union Sass_Value* sass_make_warning (const char* msg);
-
-// Make a deep cloned copy of the given sass value
-union Sass_Value* sass_clone_value (const union Sass_Value* val);
-
-// deallocate memory (incl. all copied memory)
-void sass_delete_value (const union Sass_Value* val);
-```
-
-## Example main.c
-
-```C
-#include <stdio.h>
-#include <stdint.h>
-#include "sass/context.h"
-
-union Sass_Value* call_fn_foo(const union Sass_Value* s_args, void* cookie)
-{
-  // we actually abuse the void* to store an "int"
-  return sass_make_number((size_t)cookie, "px");
-}
-

-{
-
-  // get the input file from first argument or use default
-  const char* input = argc > 1 ? argv[1] : "styles.scss";
-
-  // create the file context and get all related structs
-  struct Sass_File_Context* file_ctx = sass_make_file_context(input);
-  struct Sass_Context* ctx = sass_file_context_get_context(file_ctx);
-  struct Sass_Options* ctx_opt = sass_context_get_options(ctx);

-
-  // create list of all custom functions

-  sass_function_set_list_entry(fn_list, 0, fn_foo);
-  sass_option_set_c_functions(ctx_opt, fn_list);
-

-  int status = sass_compile_file_context(file_ctx);
-

-  else puts(sass_context_get_error_message(ctx));
-
-  // release allocated memory
-  sass_delete_file_context(file_ctx);
-
-  // exit status
-  return status;
-

-echo "foo { margin: foo(); }" > foo.scss
-./sample foo.scss => "foo { margin: 42px }"

-# LibSass smart pointer implementation
-
-LibSass uses smart pointers very similar to `shared_ptr` known
-by Boost or C++11. Implementation is a bit less modular since
-it was not needed. Various compile time debug options are
-available if you need to debug memory life-cycles.
-
-
-## Memory Classes
-
-### SharedObj
-
-Base class for the actual node implementations. This ensures
-that every object has a reference counter and other values.
-
-```c++
-class AST_Node : public SharedObj { ... };
-```
-
-### SharedPtr (base class for SharedImpl)
-
-Base class that holds on to the pointer. The reference counter
-is stored inside the pointer object directly (`SharedObj`).
-
-### SharedImpl (inherits from SharedPtr)
-
-This is the main base class for objects you use in your code. It
-will make sure that the memory it points at will be deleted once
-all copies to the same object/memory go out of scope.

-```c++
-Class* pointer = new Class(...);
-SharedImpl<Class> obj(pointer);
-```
-
-To spare the developer of typing the templated class every time,
-we created typedefs for each available AST Node specialization.
-
-```c++
-typedef SharedImpl<Number> Number_Obj;
-Number_Obj number = SASS_MEMORY_NEW(...);
-```

-## Memory life-cycles
-
-### Pointer pickups
-
-I often use the terminology of "pickup". This means the moment when
-a raw pointer not under any control is assigned to a reference counted
-object (`XYZ_Obj = XYZ_Ptr`). From that point on memory will be
-automatically released once the object goes out of scope (but only
-if the reference counter reaches zero). Main point beeing, you don't
-have to worry about memory management yourself.
-
-### Object detach
-
-Sometimes we can't return reference counted objects directly (see
-invalid covariant return types problems below). But we often still
-need to use reference objects inside a function to avoid leaks when
-something throws. For this you can use `detach`, which basically
-detaches the pointer memory from the reference counted object. So
-when the reference counted object goes out of scope, it will not
-free the attached memory. You are now again in charge of freeing
-the memory (just assign it to a reference counted object again).
-
-
-## Circular references
-
-Reference counted memory implementations are prone to circular references.
-This can be addressed by using a multi generation garbage collector. But
-for our use-case that seems overkill. There is no way so far for users
-(sass code) to create circular references. Therefore we can code around
-this possible issue. But developers should be aware of this limitation.
-
-There are AFAIR two places where circular references could happen. One is
-the `sources` member on every `Selector`. The other one can happen in the
-extend code (Node handling). The easy way to avoid this is to only assign
-complete object clones to these members. If you know the objects lifetime
-is longer than the reference you create, you can also just store the raw
-pointer. Once needed this could be solved with weak pointers.
-
-
-## Addressing the invalid covariant return types problems
-
-If you are not familiar with the mentioned problem, you may want
-to read up on covariant return types and virtual functions, i.e.

-- http://stackoverflow.com/questions/2687790/how-to-accomplish-covariant-return-types-when-returning-a-shared-ptr
-
-We hit this issue at least with the CRTP visitor pattern (eval, expand,
-listize and so forth). This means we cannot return reference counted
-objects directly. We are forced to return raw pointers or we would need
-to have a lot of explicit and expensive upcasts by callers/consumers.
-
-### Simple functions that allocate new AST Nodes
-
-In the parser step we often create new objects and can just return a
-unique pointer (meaning ownership clearly shifts back to the caller).
-The caller/consumer is responsible that the memory is freed.
-
-```c++
-typedef Number* Number_Ptr;
-int parse_integer() {
-  ... // do the parsing
-  return 42;
-}
-Number_Ptr parse_number() {
-  Number_Ptr p_nr = SASS_MEMORY_NEW(...);
-  p_nr->value(parse_integer());
-  return p_nr;
-}
-Number_Obj nr = parse_number();
-```
-
-The above would be the encouraged pattern for such simple cases.
-
-### Allocate new AST Nodes in functions that can throw
-
-There is a major caveat with the previous example, considering this
-more real-life implementation that throws an error. The throw may
-happen deep down in another function. Holding raw pointers that
-we need to free would leak in this case.
-
-```c++
-int parse_integer() {
-  ... // do the parsing
-  if (error) throw(error);
-  return 42;
-}
-```
-
-With this `parse_integer` function the previous example would leak memory.
-I guess it is pretty obvious, as the allocated memory will not be freed,
-as it was never assigned to a SharedObj value. Therefore the above code
-would better be written as:
-
-```c++
-typedef Number* Number_Ptr;
-int parse_integer() {
-  ... // do the parsing
-  if (error) throw(error);
-  return 42;
-}
-// this leaks due to pointer return
-// should return Number_Obj instead
-// though not possible for virtuals!
-Number_Ptr parse_number() {
-  Number_Obj nr = SASS_MEMORY_NEW(...);
-  nr->value(parse_integer()); // throws
-  return &nr; // Ptr from Obj
-}
-Number_Obj nr = parse_number();
-// will now be freed automatically
-```
-
-The example above unfortunately will not work as is, since we return a
-`Number_Ptr` from that function. Therefore the object allocated inside
-the function is already gone when it is picked up again by the caller.
-The easy fix for the given simplified use case would be to change the
-return type of `parse_number` to `Number_Obj`. Indeed we do it exactly
-this way in the parser. But as stated above, this will not work for
-virtual functions due to invalid covariant return types!
-
-### Return managed objects from virtual functions
-
-The easy fix would be to just create a new copy on the heap and return
-that. But this seems like a very inelegant solution to this problem. I
-mean why can't we just tell the object to treat it like a newly allocated
-object? And indeed we can. I've added a `detach` method that will tell
-the object to survive deallocation until the next pickup. This means
-that it will leak if it is not picked up by consumer.
-
-```c++
-typedef Number* Number_Ptr;
-int parse_integer() {
-  ... // do the parsing
-  if (error) throw(error);
-  return 42;
-}
-Number_Ptr parse_number() {
-  Number_Obj nr = SASS_MEMORY_NEW(...);
-  nr->value(parse_integer()); // throws
-  return nr.detach();
-}
-Number_Obj nr = parse_number();
-// will now be freed automatically
-```
-
-
-## Compile time debug options
-
-To enable memory debugging you need to define `DEBUG_SHARED_PTR`.
-This can i.e. be done in `include/sass/base.h`
-
-```c++
-define DEBUG_SHARED_PTR
-```
-
-This will print lost memory on exit to stderr. You can also use
-`setDbg(true)` on sepecific variables to emit reference counter
-increase, decrease and other events.
-
-
-## Why reinvent the wheel when there is `shared_ptr` from C++11
-
-First, implementing a smart pointer class is not really that hard. It
-was indeed also a learning experience for myself. But there are more
-profound advantages:
-
-- Better GCC 4.4 compatibility (which most code still has OOTB)
-- Not thread safe (give us some free performance on some compiler)
-- Beeing able to track memory allocations for debugging purposes
-- Adding additional features if needed (as seen in `detach`)
-- Optional: optimized weak pointer implementation possible
-
-### Thread Safety
-
-As said above, this is not thread safe currently. But we don't need
-this ATM anyway. And I guess we probably never will share AST Nodes
-across different threads.

-Plugins are shared object files (.so on *nix and .dll on win) that can be loaded by LibSass on runtime. Currently we only provide a way to load internal/custom functions from plugins. In the future we probably will also add a way to provide custom importers via plugins (needs more refactoring to [support multiple importers with some kind of priority system](https://github.com/sass/libsass/issues/962)).
-
-## plugin.cpp
-
-```C++
-#include <cstring>
-#include <iostream>
-#include <stdint.h>
-#include "sass_values.h"
-
-union Sass_Value* ADDCALL call_fn_foo(const union Sass_Value* s_args, void* cookie)

-  // put the only function in this plugin to the list
-  sass_function_set_list_entry(fn_list, 0, fn_foo);
-  // return the list
-  return fn_list;
-}
-```
-
-To compile the plugin you need to have LibSass already built as a shared library (to link against it). The commands below expect the shared library in the `lib` sub-directory (`-Llib`). The plugin and the main LibSass process should "consume" the same shared LibSass library on runtime. It will propably also work if they use different LibSass versions. In this case we check if the major versions are compatible (i.e. 3.1.3 and 3.1.1 would be considered compatible).

-## Requirements
-In order to install and setup your local development environment, there are some prerequisites:
-
-* git
-* gcc/clang/llvm (Linux: build tools, Mac OS X: XCode w/ Command Line Tools)
-* ruby w/ bundler
-
-OS X:
-First you'll need to install XCode which you can now get from the AppStore installed on your mac. After you download that and run it, then run this on the command line:
-
-````
-xcode-select --install
-````
-
-## Cloning the Projects
-
-First, clone the project and then add a line to your `~/.bash_profile` that will let other programs know where the LibSass dev files are.
-
-````
-git clone git@github.com:sass/libsass.git
-cd libsass
-echo "export SASS_LIBSASS_PATH=$(pwd)" >> ~/.bash_profile
-
-````
-
-Then, if you run the "bootstrap" script, it should clone all the other required projects.
-
-````
-./script/bootstrap
-````
-
-You should now have a `sass-spec` and `sassc` folder within the libsass folder. Both of these are clones of their respective git projects. If you want to do a pull request, remember to work in those folders. For instance, if you want to add a test (see other documentation for how to do that), make sure to commit it to your *fork* of the sass-spec github project. Also, whenever you are running tests, make sure to `pull` from the origin! We want to make sure we are testing against the newest libsass, sassc, and sass-spec!
-
-Now, try and see if you can build the project. We do that with the `make` command.
-
-````
-make
-````
-
-At this point, if you get an error, something is most likely wrong with your compiler installation. Yikes. It's hard to cover how to fix this in an article. Feel free to open an issue and we'll try and help! But, remember, before you do that, googling the error message is your friend! Many problems are solved quickly that way.
-
-## Running The Spec Against LibSass
-
-Then, to run the spec against LibSass, just run:
-
-````
-./script/spec
-````
-
-If you get an error about `SASS_LIBSASS_PATH`, you may still need to set a variable pointing to the libsass folder, like this:
-
-````
-export SASS_LIBSASS_PATH=/Users/you/path/libsass
-````
-
-...where the latter part is to the `libsass` directory you've cloned. You can get this path by typing `pwd` in the Terminal
-
-## Running the Spec Against Ruby Sass
-
-Go into the sass-spec folder that should have been cloned earlier with the "bootstrap" command. Run the following.
-
-````
-bundle install
-./sass-spec.rb
-````
-
-Voila! Now you are testing against Sass too!

-
-# Documenting some of the source map internals
-
-Since source maps are somewhat a black box to all LibSass maintainers, [I](@mgreter) will try to document my findings with source maps in LibSass, as I come across them. This document will also brievely explain how LibSass parses the source and how it outputs the result.
-
-The main storage for SourceMap mappings is the `mappings` vector:
-
-```
-# in source_map.hpp
-vector<Mapping> mappings
-# in mappings.hpp
-struct Mapping ...
-  Position original_position;
-  Position generated_position;
-```
-
-## Every parsed token has its source associated
-
-LibSass uses a lexical parser. Whenever LibSass finds a token of interest, it creates a specific `AST_Node`, which will hold a reference to the input source with line/column information. `AST_Node` is the base class for all parsed items. They are declared in `ast.hpp` and are used in `parser.hpp`. Here a simple example:
-
-```
-if (lex< custom_property_name >()) {
-  Sass::String* prop = new (ctx.mem) String_Constant(path, source_position, lexed);
-  return new (ctx.mem) Declaration(path, prop->position(), prop, ...);
-}
-```
-
-## How is the `source_position` calculated
-
-This is automatically done with `lex` in `parser.hpp`. Whenever something is lexed, the `source_position` is updated. But be aware that `source_position` points to the begining of the parsed text. If you need a mapping for the position where the parsing ended, you need to add another call to `lex` (to match nothing)!
-
-```
-lex< exactly < empty_str > >();
-end = new (ctx.mem) String_Constant(path, source_position, lexed);
-```
-
-## How are mappings for the output created
-
-So far we have collected all needed data for all tokens in the input stream. We can now use this information to create mappings when we put things into the output stream. Mappings are created via the `add_mappings` method:
-
-```
-# in source_map.hpp
-void add_mapping(AST_Node* node);
-```
-
-This method is called in two places:
-- `Inspect::append_to_buffer`
-- `Output_[Nested|Compressed]::append_to_buffer`
-
-Mappings can only be created for things that have been parsed into a `AST_Node`. Otherwise we do not have the information to create the mappings, which is the reason why LibSass currently only maps the most important tokens in source maps.

-LibSass currently expects all input to be utf8 encoded (and outputs only utf8), if you actually have any unicode characters at all. We do not support conversion between encodings, even if you declare it with a `@charset` rule. The text below was originally posted as an [issue](https://github.com/sass/libsass/issues/381) on the LibSass tracker. Since then the status is outdated as LibSass now expects your
-input to be utf8/ascii compatible, as it has been proven that reading ANSI (e.g. single byte encodings) as utf8 can lead to unexpected
-behavior, which can in the worst case lead to buffer overruns/segfaults. Therefore LibSass now checks your input to be valid utf8 encoded!
-
-### [Declaring character encodings in CSS](http://www.w3.org/International/questions/qa-css-charset.en)
-
-This [explains](http://www.w3.org/International/questions/qa-css-charset.en) how the character encoding of a css file is determined. Since we are only dealing with local files, we never have a HTTP header. So the precedence should be 'charset' rule, byte-order mark (BOM) or auto-detection (finally falling back to system default/UTF-8). This may not sound too hard to implement, but what about import rules? The CSS specs do not forbid the mixing of different encodings! I [solved that](https://github.com/mgreter/webmerge/) by converting all files to UTF-8 internally. On writing there is an option to tell the tool what encoding it should be (UTF-8 by default). One can also define if it should write a BOM or not and if it should add the charset declaration.
-
-Since my [tool]((https://github.com/mgreter/webmerge/)) is written in perl, I have a lot of utilities at hand to deal with different unicode charsets. I'm pretty sure that most OSS uses [ICU](http://site.icu-project.org/) or [libiconv](https://www.gnu.org/software/libiconv/) to convert between different encodings. But I have now idea how easy/hard this would be to integrate platform independent (it seems doable). ANSII (single byte encoding) to utf8 is basically just a conversion table (for every supported code-page).
-
-### Current status on LibSass unicode support
-
-LibSass should/is fully UTF (and therefore plain ASCII) compatible. 
-
-~~Currently LibSass seems to handle the common UTF-8 case pretty well. I believe it should correctly support all ASCII compatible encodings (like UTF-8 or Latin-1). If all includes use the same encoding, the output should be correct (in the same encoding). It should also handle unicode chars in [selectors, variable names and other identifiers](https://github.com/hcatlin/libsass/issues/244#issuecomment-34681227). This is true for all ASCII compatible encodings. So the main incompatible encodings (I'm aware of) are UTF-16/UTF-32 (which could be converted to UTF-8 with libiconv).~~
-
-LibSass 3.5 will enforce that your input is either plain ASCII (chars below 127) or utf8. It does not handle anything else, but therefore ensures that the output is in a valid form. Before version 3.5 you were able to mix different code-pages, which yielded unexpected behavior.
-
-### Current encoding auto detection
-
-LibSass currently reads all kind of BOMs and will error out if it finds something it doesn't know how to handle! It seems that it throws away the optional UTF-8 BOM (if any is found). IMO it would be nice if users could configure that (also if a charset rule should be added to the output). But it does not really take any `@charset` into account, it always assumes your input is utf8 and ignores any given `@charset`!
-
-### What is currently not supported
-
-- Using non ASCII compatible encodings (like UTF-16, Latin-1 etc.)
-- Using non ASCII characters in different encodings in different includes
-
-### What is missing to support the above cases
-
-- A way to convert between encodings (like libiconv/ICU)
-- Sniffing the charset inside the file (source is available)
-- Handling the conversion on import (and export)
-- Optional: Make output encoding configurable
-- Optional: Add optional/mandatory BOM (configurable)
-
-### Low priority feature
-
-I guess the current implementation should handle more than 99% of all real world use cases.
-A) Unicode characters are still seldomly seen (as they can be written escaped)
-~~B) It will still work if it's UTF-8 or in any of the most common known western ISO codepages.
-Although I'm not sure how this applies to asian and other "exotic" codepages!~~
-
-I guess the biggest Problem is to have libiconv/ICU (or some other) library as a dependency. Since it contains a lot of rules for the conversions, I see it as the only way to handle this correctly. Once that is sorted out it should be pretty much straight forward to implement the missing pieces (in parser.cpp - Parser::parse should return encoding and add Parser::sniff_charset, then convert the source byte stream to UTF-8).

-#
-# SYNOPSIS
-#
-#   AX_CXX_COMPILE_STDCXX_11([ext|noext],[mandatory|optional])
-#
-# DESCRIPTION
-#
-#   Check for baseline language coverage in the compiler for the C++11
-#   standard; if necessary, add switches to CXXFLAGS to enable support.
-#
-#   The first argument, if specified, indicates whether you insist on an
-#   extended mode (e.g. -std=gnu++11) or a strict conformance mode (e.g.
-#   -std=c++11).  If neither is specified, you get whatever works, with
-#   preference for an extended mode.
-#
-#   The second argument, if specified 'mandatory' or if left unspecified,
-#   indicates that baseline C++11 support is required and that the macro
-#   should error out if no mode with that support is found.  If specified
-#   'optional', then configuration proceeds regardless, after defining
-#   HAVE_CXX11 if and only if a supporting mode is found.

- NOTES:
-
- - The print* functions print to cerr. This allows our testing frameworks (like sass-spec) to ignore the output, which
-   is very helpful when debugging. The format of the output is mainly to wrap things in square brackets to match what
-   ruby already outputs (to make comparisons easier).
-
- - For the direct porting effort, we're trying to port method-for-method until we get all the tests passing.
-   Where applicable, I've tried to include the ruby code above the function for reference until all our tests pass.
-   The ruby code isn't always directly portable, so I've tried to include any modified ruby code that was actually
-   used for the porting.
-
- - DO NOT try to optimize yet. We get a tremendous benefit out of comparing the output of each stage of the extend to the ruby
-   output at the same stage. This makes it much easier to determine where problems are. Try to keep as close to
-   the ruby code as you can until we have all the sass-spec tests passing. Then, we should optimize. However, if you see
-   something that could probably be optimized, let's not forget it. Add a // TODO: or // IMPROVEMENT: comment.
-
- - Coding conventions in this file (these may need to be changed before merging back into master)
-   - Very basic hungarian notation:
-     p prefix for pointers (pSelector)
-     no prefix for value types and references (selector)
-   - Use STL iterators where possible
-   - prefer verbose naming over terse naming
-   - use typedefs for STL container types for make maintenance easier
-
- - You may see a lot of comments that say "// TODO: is this the correct combinator?". See the comment referring to combinators
-   in extendCompoundSelector for a more extensive explanation of my confusion. I think our divergence in data model from ruby
-   sass causes this to be necessary.
-
-
- GLOBAL TODOS:
-
- - wrap the contents of the print functions in DEBUG preprocesser conditionals so they will be optimized away in non-debug mode.
-
- - consider making the extend* functions member functions to avoid passing around ctx and subset_map map around. This has the
-   drawback that the implementation details of the operator are then exposed to the outside world, which is not ideal and
-   can cause additional compile time dependencies.
-
- - mark the helper methods in this file static to given them compilation unit linkage.
-
- - implement parent directive matching
-
- - fix compilation warnings for unused Extend members if we really don't need those references anymore.

-   There are a lot of stumbling blocks when trying to port the ruby extend code to C++. The biggest is the choice of
-   data type. The ruby code will pretty seamlessly switch types between an Array<SimpleSequence or Op> (libsass'
-   equivalent is the Complex_Selector) to a Sequence, which contains more metadata about the sequence than just the
-   selector info. They also have the ability to have arbitrary nestings of arrays like [1, [2]], which is hard to
-   implement using Array equivalents in C++ (like the deque or vector). They also have the ability to include nil
-   in the arrays, like [1, nil, 3], which has potential semantic differences than an empty array [1, [], 3]. To be
-   able to represent all of these as unique cases, we need to create a tree of variant objects. The tree nature allows
-   the inconsistent nesting levels. The variant nature (while making some of the C++ code uglier) allows the code to
-   more closely match the ruby code, which is a huge benefit when attempting to implement an complex algorithm like
-   the Extend operator.
-
-   Note that the current libsass data model also pairs the combinator with the Complex_Selector that follows it, but
-   ruby sass has no such restriction, so we attempt to create a data structure that can handle them split apart.

-// Notes about delayed: some ast nodes can have delayed evaluation so
-// they can preserve their original semantics if needed. This is most
-// prominently exhibited by the division operation, since it is not
-// only a valid operation, but also a valid css statement (i.e. for
-// fonts, as in `16px/24px`). When parsing lists and expression we
-// unwrap single items from lists and other operations. A nested list
-// must not be delayed, only the items of the first level sometimes
-// are delayed (as with argument lists). To achieve this we need to
-// pass status to the list parser, so this can be set correctly.
-// Another case with delayed values are colors. In compressed mode
-// only processed values get compressed (other are left as written).

-If you want to write an option parser, and have it be good, there are
-two ways to do it.  The Right Way, and the Wrong Way.
-
-The Wrong Way is to sit down and write an option parser.  We've all done
-that.
-
-The Right Way is to write some complex configurable program with so many
-options that you hit the limit of your frustration just trying to
-manage them all, and defer it with duct-tape solutions until you see
-exactly to the core of the problem, and finally snap and write an
-awesome option parser.
-
-If you want to write an option parser, don't write an option parser.
-Write a package manager, or a source control system, or a service
-restarter, or an operating system.  You probably won't end up with a
-good one of those, but if you don't give up, and you are relentless and
-diligent enough in your procrastination, you may just end up with a very
-nice option parser.
-
-## USAGE
-
-    // my-program.js
-    var nopt = require("nopt")
-      , Stream = require("stream").Stream
-      , path = require("path")
-      , knownOpts = { "foo" : [String, null]
-                    , "bar" : [Stream, Number]
-                    , "baz" : path
-                    , "bloo" : [ "big", "medium", "small" ]
-                    , "flag" : Boolean
-                    , "pick" : Boolean
-                    , "many1" : [String, Array]
-                    , "many2" : [path]
-                    }
-      , shortHands = { "foofoo" : ["--foo", "Mr. Foo"]

-                 // everything is optional.
-                 // knownOpts and shorthands default to {}
-                 // arg list defaults to process.argv
-                 // slice defaults to 2
-      , parsed = nopt(knownOpts, shortHands, process.argv, 2)
-    console.log(parsed)
-
-This would give you support for any of the following:
-
-```bash
-$ node my-program.js --foo "blerp" --no-flag
-{ "foo" : "blerp", "flag" : false }
-
-$ node my-program.js ---bar 7 --foo "Mr. Hand" --flag
-{ bar: 7, foo: "Mr. Hand", flag: true }
-
-$ node my-program.js --foo "blerp" -f -----p
-{ foo: "blerp", flag: true, pick: true }
-
-$ node my-program.js -fp --foofoo
-{ foo: "Mr. Foo", flag: true, pick: true }
-
-$ node my-program.js --foofoo -- -fp  # -- stops the flag parsing.
-{ foo: "Mr. Foo", argv: { remain: ["-fp"] } }
-
-$ node my-program.js --blatzk -fp # unknown opts are ok.
-{ blatzk: true, flag: true, pick: true }
-
-$ node my-program.js --blatzk=1000 -fp # but you need to use = if they have a value
-{ blatzk: 1000, flag: true, pick: true }
-
-$ node my-program.js --no-blatzk -fp # unless they start with "no-"
-{ blatzk: false, flag: true, pick: true }
-
-$ node my-program.js --baz b/a/z # known paths are resolved.
-{ baz: "/Users/isaacs/b/a/z" }
-
-# if Array is one of the types, then it can take many
-# values, and will always be an array.  The other types provided
-# specify what types are allowed in the list.
-
-$ node my-program.js --many1 5 --many1 null --many1 foo
-{ many1: ["5", "null", "foo"] }
-
-$ node my-program.js --many2 foo --many2 bar
-{ many2: ["/path/to/foo", "path/to/bar"] }
-```
-
-Read the tests at the bottom of `lib/nopt.js` for more examples of
-what this puppy can do.
-
-## Types
-
-The following types are supported, and defined on `nopt.typeDefs`
-
-* String: A normal string.  No parsing is done.
-* path: A file system path.  Gets resolved against cwd if not absolute.
-* url: A url.  If it doesn't parse, it isn't accepted.
-* Number: Must be numeric.
-* Date: Must parse as a date. If it does, and `Date` is one of the options,
-  then it will return a Date object, not a string.
-* Boolean: Must be either `true` or `false`.  If an option is a boolean,
-  then it does not need a value, and its presence will imply `true` as
-  the value.  To negate boolean flags, do `--no-whatever` or `--whatever
-  false`
-* NaN: Means that the option is strictly not allowed.  Any value will
-  fail.
-* Stream: An object matching the "Stream" class in node.  Valuable
-  for use when validating programmatically.  (npm uses this to let you
-  supply any WriteStream on the `outfd` and `logfd` config options.)
-* Array: If `Array` is specified as one of the types, then the value
-  will be parsed as a list of options.  This means that multiple values
-  can be specified, and that the value will always be an array.
-
-If a type is an array of values not on this list, then those are
-considered valid values.  For instance, in the example above, the
-`--bloo` option can only be one of `"big"`, `"medium"`, or `"small"`,
-and any other value will be rejected.
-
-When parsing unknown fields, `"true"`, `"false"`, and `"null"` will be
-interpreted as their JavaScript equivalents.
-
-You can also mix types and values, or multiple types, in a list.  For
-instance `{ blah: [Number, null] }` would allow a value to be set to
-either a Number or null.  When types are ordered, this implies a
-preference, and the first type that can be used to properly interpret
-the value will be used.
-
-To define a new type, add it to `nopt.typeDefs`.  Each item in that
-hash is an object with a `type` member and a `validate` method.  The
-`type` member is an object that matches what goes in the type list.  The
-`validate` method is a function that gets called with `validate(data,
-key, val)`.  Validate methods should assign `data[key]` to the valid
-value of `val` if it can be handled properly, or return boolean
-`false` if it cannot.
-
-You can also call `nopt.clean(data, types, typeDefs)` to clean up a
-config object and remove its invalid properties.
-
-## Error Handling
-
-By default, nopt outputs a warning to standard error when invalid values for
-known options are found.  You can change this behavior by assigning a method
-to `nopt.invalidHandler`.  This method will be called with
-the offending `nopt.invalidHandler(key, val, types)`.
-
-If no `nopt.invalidHandler` is assigned, then it will console.error
-its whining.  If it is assigned to boolean `false` then the warning is
-suppressed.
-
-## Abbreviations
-
-Yes, they are supported.  If you define options like this:
-
-```javascript
-{ "foolhardyelephants" : Boolean
-, "pileofmonkeys" : Boolean }
-```
-
-Then this will work:
-
-```bash
-node program.js --foolhar --pil
-node program.js --no-f --pileofmon
-# etc.
-```
-
-## Shorthands
-
-Shorthands are a hash of shorter option names to a snippet of args that
-they expand to.
-
-If multiple one-character shorthands are all combined, and the
-combination does not unambiguously match any other option or shorthand,
-then they will be broken up into their constituent parts.  For example:
-
-```json
-{ "s" : ["--loglevel", "silent"]

-
-## The Rest of the args
-
-The config object returned by nopt is given a special member called
-`argv`, which is an object with the following fields:
-
-* `remain`: The remaining args after all the parsing has occurred.
-* `original`: The args as they originally appeared.
-* `cooked`: The args after flags and shorthands are expanded.
-
-## Slicing
-
-Node programs are called with more or less the exact argv as it appears
-in C land, after the v8 and node-specific options have been plucked off.
-As such, `argv[0]` is always `node` and `argv[1]` is always the
-JavaScript program being run.
-
-That's usually not very useful to you.  So they're sliced off by
-default.  If you want them, then you can pass in `0` as the last
-argument, or any other number that you'd like to slice off the start of
-the list.

-### v4.0.2
-
-* Added installation instructions.
-
-### v4.0.1
-
-* Fix bugs where `log.progressEnabled` got out of sync with how `gauge` kept
-  track of these things resulting in a progressbar that couldn't be disabled.
-
-### v4.0.0
-
-* Allow creating log levels that are an empty string or 0.
-
-### v3.1.2
-
-* Update to `gauge@1.6.0` adding support for default values for template
-  items.
-
-### v3.1.1
-
-* Update to `gauge@1.5.3` to fix to `1.x` compatibility when it comes to
-  when a progress bar is enabled.  In `1.x` if you didn't have a TTY the
-  progress bar was never shown.  In `2.x` it merely defaults to disabled,
-  but you can enable it explicitly if you still want progress updates.
-
-### v3.1.0
-
-* Update to `gauge@2.5.2`:
-  * Updates the `signal-exit` dependency which fixes an incompatibility with
-    the node profiler.
-  * Uses externalizes its ansi code generation in `console-control-strings`
-* Make the default progress bar include the last line printed, colored as it
-  would be when printing to a tty.
-
-### v3.0.0
-
-* Switch to `gauge@2.0.0`, for better performance, better look.
-* Set stderr/stdout blocking if they're tty's, so that we can hide a
-  progress bar going to stderr and then safely print to stdout.  Without
-  this the two can end up overlapping producing confusing and sometimes
-  corrupted output.
-
-### v2.0.0
-
-* Make the `error` event non-fatal so that folks can use it as a prefix.
-
-### v1.0.0
-
-* Add progress bar with `gauge@1.1.0`

-# npmlog
-
-The logger util that npm uses.
-
-This logger is very basic.  It does the logging for npm.  It supports
-custom levels and colored output.
-
-By default, logs are written to stderr.  If you want to send log messages
-to outputs other than streams, then you can change the `log.stream`
-member, or you can just listen to the events that it emits, and do
-whatever you want with them.
-
-# Installation
-
-```console
-npm install npmlog --save
-```
-
-# Basic Usage
-
-```javascript
-var log = require('npmlog')
-
-// additional stuff ---------------------------+
-// message ----------+                         |
-// prefix ----+      |                         |
-// level -+   |      |                         |
-//        v   v      v                         v
-    log.info('fyi', 'I have a kitty cat: %j', myKittyCat)
-```
-
-## log.level
-
-* {String}
-
-The level to display logs at.  Any logs at or above this level will be
-displayed.  The special level `silent` will prevent anything from being
-displayed ever.
-
-## log.record
-
-* {Array}
-
-An array of all the log messages that have been entered.
-
-## log.maxRecordSize
-
-* {Number}
-
-The maximum number of records to keep.  If log.record gets bigger than
-10% over this value, then it is sliced down to 90% of this value.
-
-The reason for the 10% window is so that it doesn't have to resize a
-large array on every log entry.
-
-## log.prefixStyle
-
-* {Object}
-
-A style object that specifies how prefixes are styled.  (See below)
-
-## log.headingStyle
-
-* {Object}
-
-A style object that specifies how the heading is styled.  (See below)
-
-## log.heading
-
-* {String} Default: ""
-
-If set, a heading that is printed at the start of every line.
-
-## log.stream
-
-* {Stream} Default: `process.stderr`
-
-The stream where output is written.
-
-## log.enableColor()
-
-Force colors to be used on all messages, regardless of the output
-stream.
-
-## log.disableColor()
-
-Disable colors on all messages.
-
-## log.enableProgress()
-
-Enable the display of log activity spinner and progress bar
-
-## log.disableProgress()
-
-Disable the display of a progress bar
-
-## log.enableUnicode()
-
-Force the unicode theme to be used for the progress bar.
-
-## log.disableUnicode()
-
-Disable the use of unicode in the progress bar.
-
-## log.setGaugeTemplate(template)
-
-Set a template for outputting the progress bar. See the [gauge documentation] for details.
-
-[gauge documentation]: https://npmjs.com/package/gauge
-
-## log.setGaugeThemeset(themes)
-
-Select a themeset to pick themes from for the progress bar. See the [gauge documentation] for details.
-
-## log.pause()
-
-Stop emitting messages to the stream, but do not drop them.
-
-## log.resume()
-
-Emit all buffered messages that were written while paused.
-
-## log.log(level, prefix, message, ...)
-
-* `level` {String} The level to emit the message at
-* `prefix` {String} A string prefix.  Set to "" to skip.
-* `message...` Arguments to `util.format`
-
-Emit a log message at the specified level.
-
-## log\[level](prefix, message, ...)
-
-For example,
-
-* log.silly(prefix, message, ...)
-* log.verbose(prefix, message, ...)
-* log.info(prefix, message, ...)
-* log.http(prefix, message, ...)
-* log.warn(prefix, message, ...)
-* log.error(prefix, message, ...)
-
-Like `log.log(level, prefix, message, ...)`.  In this way, each level is
-given a shorthand, so you can do `log.info(prefix, message)`.
-
-## log.addLevel(level, n, style, disp)
-
-* `level` {String} Level indicator
-* `n` {Number} The numeric level
-* `style` {Object} Object with fg, bg, inverse, etc.
-* `disp` {String} Optional replacement for `level` in the output.
-
-Sets up a new level with a shorthand function and so forth.
-
-Note that if the number is `Infinity`, then setting the level to that
-will cause all log messages to be suppressed.  If the number is
-`-Infinity`, then the only way to show it is to enable all log messages.
-
-## log.newItem(name, todo, weight)
-
-* `name` {String} Optional; progress item name.
-* `todo` {Number} Optional; total amount of work to be done. Default 0.
-* `weight` {Number} Optional; the weight of this item relative to others. Default 1.
-
-This adds a new `are-we-there-yet` item tracker to the progress tracker. The
-object returned has the `log[level]` methods but is otherwise an
-`are-we-there-yet` `Tracker` object.
-
-## log.newStream(name, todo, weight)
-
-This adds a new `are-we-there-yet` stream tracker to the progress tracker. The
-object returned has the `log[level]` methods but is otherwise an
-`are-we-there-yet` `TrackerStream` object.
-
-## log.newGroup(name, weight)
-
-This adds a new `are-we-there-yet` tracker group to the progress tracker. The
-object returned has the `log[level]` methods but is otherwise an
-`are-we-there-yet` `TrackerGroup` object.
-
-# Events
-
-Events are all emitted with the message object.
-
-* `log` Emitted for all messages
-* `log.<level>` Emitted for all messages with the `<level>` level.
-* `<prefix>` Messages with prefixes also emit their prefix as an event.
-
-# Style Objects
-
-Style objects can have the following fields:
-
-* `fg` {String} Color for the foreground text
-* `bg` {String} Color for the background
-* `bold`, `inverse`, `underline` {Boolean} Set the associated property
-* `bell` {Boolean} Make a noise (This is pretty annoying, probably.)
-
-# Message Objects
-
-Every log event is emitted with a message object, and the `log.record`
-list contains all of them that have been created.  They have the
-following fields:
-
-* `id` {Number}
-* `level` {String}
-* `prefix` {String}
-* `message` {String} Result of `util.format()`
-* `messageRaw` {Array} Arguments to `util.format()`
-
-# Blocking TTYs
-
-We use [`set-blocking`](https://npmjs.com/package/set-blocking) to set
-stderr and stdout blocking if they are tty's and have the setBlocking call.
-This is a work around for an issue in early versions of Node.js 6.x, which
-made stderr and stdout non-blocking on OSX. (They are always blocking
-Windows and were never blocking on Linux.) `npmlog` needs them to be blocking
-so that it can allow output to stdout and stderr to be interlaced.

-# osenv
-
-Look up environment settings specific to different operating systems.
-
-## Usage
-
-```javascript
-var osenv = require('osenv')
-var path = osenv.path()
-var user = osenv.user()
-// etc.
-
-// Some things are not reliably in the env, and have a fallback command:
-var h = osenv.hostname(function (er, hostname) {
-  h = hostname
-})
-// This will still cause it to be memoized, so calling osenv.hostname()
-// is now an immediate operation.
-
-// You can always send a cb, which will get called in the nextTick
-// if it's been memoized, or wait for the fallback data if it wasn't
-// found in the environment.
-osenv.hostname(function (er, hostname) {
-  if (er) console.error('error looking up hostname')
-  else console.log('this machine calls itself %s', hostname)
-})
-```
-
-## osenv.hostname()
-
-The machine name.  Calls `hostname` if not found.
-
-## osenv.user()
-
-The currently logged-in user.  Calls `whoami` if not found.
-
-## osenv.prompt()
-
-Either PS1 on unix, or PROMPT on Windows.
-
-## osenv.tmpdir()
-
-The place where temporary files should be created.
-
-## osenv.home()
-
-No place like it.
-
-## osenv.path()
-
-An array of the places that the operating system will search for
-executables.
-
-## osenv.editor() 
-
-Return the executable name of the editor program.  This uses the EDITOR
-and VISUAL environment variables, and falls back to `vi` on Unix, or
-`notepad.exe` on Windows.
-
-## osenv.shell()
-
-The SHELL on Unix, which Windows calls the ComSpec.  Defaults to 'bash'
-or 'cmd'.

-# performance-now [![Build Status](https://travis-ci.org/braveg1rl/performance-now.png?branch=master)](https://travis-ci.org/braveg1rl/performance-now) [![Dependency Status](https://david-dm.org/braveg1rl/performance-now.png)](https://david-dm.org/braveg1rl/performance-now)
-
-Implements a function similar to `performance.now` (based on `process.hrtime`).
-
-Modern browsers have a `window.performance` object with - among others - a `now` method which gives time in milliseconds, but with sub-millisecond precision. This module offers the same function based on the Node.js native `process.hrtime` function.
-
-Using `process.hrtime` means that the reported time will be monotonically increasing, and not subject to clock-drift.
-
-According to the [High Resolution Time specification](http://www.w3.org/TR/hr-time/), the number of milliseconds reported by `performance.now` should be relative to the value of `performance.timing.navigationStart`.
-
-In the current version of the module (2.0) the reported time is relative to the time the current Node process has started (inferred from `process.uptime()`).
-
-Version 1.0 reported a different time. The reported time was relative to the time the module was loaded (i.e. the time it was first `require`d). If you need this functionality, version 1.0 is still available on NPM.
-
-## Example usage
-
-```javascript
-var now = require("performance-now")
-var start = now()
-var end = now()
-console.log(start.toFixed(3)) // the number of milliseconds the current node process is running
-console.log((start-end).toFixed(3)) // ~ 0.002 on my system
-```
-
-Running the now function two times right after each other yields a time difference of a few microseconds. Given this overhead, I think it's best to assume that the precision of intervals computed with this method is not higher than 10 microseconds, if you don't know the exact overhead on your own system.

+
+## 2.2.1 (2020-01-04)
+
+* Fixes [#49](https://github.com/micromatch/picomatch/issues/49), so that braces with no sets or ranges are now propertly treated as literals.
+
+## 2.2.0 (2020-01-04)
+
+* Disable fastpaths mode for the parse method ([5b8d33f](https://github.com/micromatch/picomatch/commit/5b8d33f))
+* Add `tokens`, `slashes`, and `parts` to the object returned by `picomatch.scan()`.

+<strong>Blazing fast and accurate glob matcher written in JavaScript.</strong></br>
+<em>No dependencies and full support for standard and extended Bash glob features, including braces, extglobs, POSIX brackets, and regular expressions.</em>
+</p>
+
+<br>
+<br>
+
+## Why picomatch?
+
+* **Lightweight** - No dependencies
+* **Minimal** - Tiny API surface. Main export is a function that takes a glob pattern and returns a matcher function.
+* **Fast** - Loads in about 2ms (that's several times faster than a [single frame of a HD movie](http://www.endmemo.com/sconvert/framespersecondframespermillisecond.php) at 60fps)
+* **Performant** - Use the returned matcher function to speed up repeat matching (like when watching files)
+* **Accurate matching** - Using wildcards (`*` and `?`), globstars (`**`) for nested directories, [advanced globbing](#advanced-globbing) with extglobs, braces, and POSIX brackets, and support for escaping special characters with `\` or quotes.
+* **Well tested** - Thousands of unit tests

+
+## Usage
+
+The main export is a function that takes a glob pattern and an options object and returns a function for matching strings.
+
+```js
+const pm = require('picomatch');
+const isMatch = pm('*.js');
+
+console.log(isMatch('abcd')); //=> false
+console.log(isMatch('a.js')); //=> true
+console.log(isMatch('a.md')); //=> false

+
+## API
+
+### [picomatch](lib/picomatch.js#L32)
+
+Creates a matcher function from one or more glob patterns. The returned function takes a string to match as its first argument, and returns true if the string is a match.

+
+## Options
+
+### Picomatch options
+
+The following options may be used with the main `picomatch()` function or any of the methods on the picomatch API.
+
+| **Option** | **Type** | **Default value** | **Description** |
+| --- | --- | --- | --- |
+| `basename`            | `boolean`      | `false`     | If set, then patterns without slashes will be matched against the basename of the path if it contains slashes.  For example, `a?b` would match the path `/xyz/123/acb`, but not `/xyz/acb/123`. |
+| `bash`                | `boolean`      | `false`     | Follow bash matching rules more strictly - disallows backslashes as escape characters, and treats single stars as globstars (`**`). |
+| `capture`             | `boolean`      | `undefined` | Return regex matches in supporting methods. |
+| `contains`            | `boolean`      | `undefined` | Allows glob to match any part of the given string(s). |
+| `cwd`                 | `string`       | `process.cwd()` | Current working directory. Used by `picomatch.split()` |
+| `debug`               | `boolean`      | `undefined` | Debug regular expressions when an error is thrown. |
+| `dot`                 | `boolean`      | `false`     | Enable dotfile matching. By default, dotfiles are ignored unless a `.` is explicitly defined in the pattern, or `options.dot` is true |
+| `expandRange`         | `function`     | `undefined` | Custom function for expanding ranges in brace patterns, such as `{a..z}`. The function receives the range values as two arguments, and it must return a string to be used in the generated regex. It's recommended that returned strings be wrapped in parentheses. |
+| `failglob`            | `boolean`      | `false`     | Throws an error if no matches are found. Based on the bash option of the same name. |
+| `fastpaths`           | `boolean`      | `true`      | To speed up processing, full parsing is skipped for a handful common glob patterns. Disable this behavior by setting this option to `false`. |
+| `flags`               | `string`      | `undefined` | Regex flags to use in the generated regex. If defined, the `nocase` option will be overridden. |
+| [format](#optionsformat) | `function` | `undefined` | Custom function for formatting the returned string. This is useful for removing leading slashes, converting Windows paths to Posix paths, etc. |
+| `ignore`              | `array\|string` | `undefined` | One or more glob patterns for excluding strings that should not be matched from the result. |
+| `keepQuotes`          | `boolean`      | `false`     | Retain quotes in the generated regex, since quotes may also be used as an alternative to backslashes.  |
+| `literalBrackets`     | `boolean`      | `undefined` | When `true`, brackets in the glob pattern will be escaped so that only literal brackets will be matched. |
+| `matchBase`           | `boolean`      | `false`     | Alias for `basename` |
+| `maxLength`           | `boolean`      | `65536`     | Limit the max length of the input string. An error is thrown if the input string is longer than this value. |
+| `nobrace`             | `boolean`      | `false`     | Disable brace matching, so that `{a,b}` and `{1..3}` would be treated as literal characters. |
+| `nobracket`           | `boolean`      | `undefined` | Disable matching with regex brackets. |
+| `nocase`              | `boolean`      | `false`     | Make matching case-insensitive. Equivalent to the regex `i` flag. Note that this option is overridden by the `flags` option. |
+| `nodupes`             | `boolean`      | `true`      | Deprecated, use `nounique` instead. This option will be removed in a future major release. By default duplicates are removed. Disable uniquification by setting this option to false. |
+| `noext`               | `boolean`      | `false`     | Alias for `noextglob` |
+| `noextglob`           | `boolean`      | `false`     | Disable support for matching with extglobs (like `+(a\|b)`) |
+| `noglobstar`          | `boolean`      | `false`     | Disable support for matching nested directories with globstars (`**`) |
+| `nonegate`            | `boolean`      | `false`     | Disable support for negating with leading `!` |
+| `noquantifiers`       | `boolean`      | `false`     | Disable support for regex quantifiers (like `a{1,2}`) and treat them as brace patterns to be expanded. |
+| [onIgnore](#optionsonIgnore) | `function` | `undefined` | Function to be called on ignored items. |
+| [onMatch](#optionsonMatch) | `function` | `undefined` | Function to be called on matched items. |
+| [onResult](#optionsonResult) | `function` | `undefined` | Function to be called on all items, regardless of whether or not they are matched or ignored. |
+| `posix`               | `boolean`      | `false`     | Support POSIX character classes ("posix brackets"). |
+| `posixSlashes`        | `boolean`      | `undefined` | Convert all slashes in file paths to forward slashes. This does not convert slashes in the glob pattern itself |
+| `prepend`             | `boolean`      | `undefined` | String to prepend to the generated regex used for matching. |
+| `regex`               | `boolean`      | `false`     | Use regular expression rules for `+` (instead of matching literal `+`), and for stars that follow closing parentheses or brackets (as in `)*` and `]*`). |
+| `strictBrackets`      | `boolean`      | `undefined` | Throw an error if brackets, braces, or parens are imbalanced. |
+| `strictSlashes`       | `boolean`      | `undefined` | When true, picomatch won't match trailing slashes with single stars. |
+| `unescape`            | `boolean`      | `undefined` | Remove backslashes preceding escaped characters in the glob pattern. By default, backslashes are retained. |
+| `unixify`             | `boolean`      | `undefined` | Alias for `posixSlashes`, for backwards compatibility. |
+
+picomatch has automatic detection for regex positive and negative lookbehinds. If the pattern contains a negative lookbehind, you must be using Node.js >= 8.10 or else picomatch will throw an error.
+
+### Scan Options
+
+In addition to the main [picomatch options](#picomatch-options), the following options may also be used with the [.scan](#scan) method.
+
+| **Option** | **Type** | **Default value** | **Description** |
+| --- | --- | --- | --- |
+| `tokens` | `boolean` | `false` | When `true`, the returned object will include an array of tokens (objects), representing each path "segment" in the scanned glob pattern |
+| `parts` | `boolean` | `false` | When `true`, the returned object will include an array of strings representing each path "segment" in the scanned glob pattern. This is automatically enabled when `options.tokens` is true |
+
+**Example**
+
+```js
+const picomatch = require('picomatch');
+const result = picomatch.scan('!./foo/*.js', { tokens: true });
+console.log(result);
+// {
+//   prefix: '!./',
+//   input: '!./foo/*.js',
+//   start: 3,
+//   base: 'foo',
+//   glob: '*.js',
+//   isBrace: false,
+//   isBracket: false,
+//   isGlob: true,
+//   isExtglob: false,
+//   isGlobstar: false,
+//   negated: true,
+//   maxDepth: 2,
+//   tokens: [
+//     { value: '!./', depth: 0, isGlob: false, negated: true, isPrefix: true },
+//     { value: 'foo', depth: 1, isGlob: false },
+//     { value: '*.js', depth: 1, isGlob: true }
+//   ],
+//   slashes: [ 2, 6 ],
+//   parts: [ 'foo', '*.js' ]
+// }
+```
+
+<br>
+
+### Options Examples
+
+#### options.expandRange
+
+**Type**: `function`
+
+**Default**: `undefined`
+
+Custom function for expanding ranges in brace patterns. The [fill-range](https://github.com/jonschlinkert/fill-range) library is ideal for this purpose, or you can use custom code to do whatever you need.
+
+**Example**
+
+The following example shows how to create a glob that matches a folder
+
+```js
+const fill = require('fill-range');
+const regex = pm.makeRe('foo/{01..25}/bar', {
+  expandRange(a, b) {
+    return `(${fill(a, b, { toRegex: true })})`;
+  }
+});
+
+console.log(regex);
+//=> /^(?:foo\/((?:0[1-9]|1[0-9]|2[0-5]))\/bar)$/
+
+console.log(regex.test('foo/00/bar'))  // false
+console.log(regex.test('foo/01/bar'))  // true
+console.log(regex.test('foo/10/bar')) // true
+console.log(regex.test('foo/22/bar')) // true
+console.log(regex.test('foo/25/bar')) // true
+console.log(regex.test('foo/26/bar')) // false
+```
+
+#### options.format
+
+**Type**: `function`
+
+**Default**: `undefined`
+
+Custom function for formatting strings before they're matched.
+
+**Example**
+
+```js
+// strip leading './' from strings
+const format = str => str.replace(/^\.\//, '');
+const isMatch = picomatch('foo/*.js', { format });
+console.log(isMatch('./foo/bar.js')); //=> true
+```
+
+#### options.onMatch
+
+```js
+const onMatch = ({ glob, regex, input, output }) => {
+  console.log({ glob, regex, input, output });
+};
+
+const isMatch = picomatch('*', { onMatch });
+isMatch('foo');
+isMatch('bar');
+isMatch('baz');
+```
+
+#### options.onIgnore
+
+```js
+const onIgnore = ({ glob, regex, input, output }) => {
+  console.log({ glob, regex, input, output });
+};
+
+const isMatch = picomatch('*', { onIgnore, ignore: 'f*' });
+isMatch('foo');
+isMatch('bar');
+isMatch('baz');
+```
+
+#### options.onResult
+
+```js
+const onResult = ({ glob, regex, input, output }) => {
+  console.log({ glob, regex, input, output });
+};
+
+const isMatch = picomatch('*', { onResult, ignore: 'f*' });
+isMatch('foo');
+isMatch('bar');
+isMatch('baz');
+```

+## Globbing features
+
+* [Basic globbing](#basic-globbing) (Wildcard matching)
+* [Advanced globbing](#advanced-globbing) (extglobs, posix brackets, brace matching)
+
+### Basic globbing
+
+| **Character** | **Description** |
+| --- | --- |
+| `*` | Matches any character zero or more times, excluding path separators. Does _not match_ path separators or hidden files or directories ("dotfiles"), unless explicitly enabled by setting the `dot` option to `true`. |
+| `**` | Matches any character zero or more times, including path separators. Note that `**` will only match path separators (`/`, and `\\` on Windows) when they are the only characters in a path segment. Thus, `foo**/bar` is equivalent to `foo*/bar`, and `foo/a**b/bar` is equivalent to `foo/a*b/bar`, and _more than two_ consecutive stars in a glob path segment are regarded as _a single star_. Thus, `foo/***/bar` is equivalent to `foo/*/bar`. |
+| `?` | Matches any character excluding path separators one time. Does _not match_ path separators or leading dots.  |
+| `[abc]` | Matches any characters inside the brackets. For example, `[abc]` would match the characters `a`, `b` or `c`, and nothing else. |
+
+#### Matching behavior vs. Bash
+
+Picomatch's matching features and expected results in unit tests are based on Bash's unit tests and the Bash 4.3 specification, with the following exceptions:
+
+* Bash will match `foo/bar/baz` with `*`. Picomatch only matches nested directories with `**`.
+* Bash greedily matches with negated extglobs. For example, Bash 4.3 says that `!(foo)*` should match `foo` and `foobar`, since the trailing `*` bracktracks to match the preceding pattern. This is very memory-inefficient, and IMHO, also incorrect. Picomatch would return `false` for both `foo` and `foobar`.
+
+<br>
+
+### Advanced globbing
+
+* [extglobs](#extglobs)
+* [POSIX brackets](#posix-brackets)
+* [Braces](#brace-expansion)
+
+#### Extglobs
+
+| **Pattern** | **Description** |
+| --- | --- |
+| `@(pattern)` | Match _only one_ consecutive occurrence of `pattern` |
+| `*(pattern)` | Match _zero or more_ consecutive occurrences of `pattern` |
+| `+(pattern)` | Match _one or more_ consecutive occurrences of `pattern` |
+| `?(pattern)` | Match _zero or **one**_ consecutive occurrences of `pattern` |
+| `!(pattern)` | Match _anything but_ `pattern` |
+
+**Examples**
+
+```js
+const pm = require('picomatch');
+
+// *(pattern) matches ZERO or more of "pattern"
+console.log(pm.isMatch('a', 'a*(z)')); // true
+console.log(pm.isMatch('az', 'a*(z)')); // true
+console.log(pm.isMatch('azzz', 'a*(z)')); // true
+
+// +(pattern) matches ONE or more of "pattern"
+console.log(pm.isMatch('a', 'a*(z)')); // true
+console.log(pm.isMatch('az', 'a*(z)')); // true
+console.log(pm.isMatch('azzz', 'a*(z)')); // true
+
+// supports multiple extglobs
+console.log(pm.isMatch('foo.bar', '!(foo).!(bar)')); // false
+
+// supports nested extglobs
+console.log(pm.isMatch('foo.bar', '!(!(foo)).!(!(bar))')); // true
+```
+
+#### POSIX brackets
+
+POSIX classes are disabled by default. Enable this feature by setting the `posix` option to true.
+
+**Enable POSIX bracket support**
+
+```js
+console.log(pm.makeRe('[[:word:]]+', { posix: true }));
+//=> /^(?:(?=.)[A-Za-z0-9_]+\/?)$/
+```
+
+**Supported POSIX classes**
+
+The following named POSIX bracket expressions are supported:
+
+* `[:alnum:]` - Alphanumeric characters, equ `[a-zA-Z0-9]`
+* `[:alpha:]` - Alphabetical characters, equivalent to `[a-zA-Z]`.
+* `[:ascii:]` - ASCII characters, equivalent to `[\\x00-\\x7F]`.
+* `[:blank:]` - Space and tab characters, equivalent to `[ \\t]`.
+* `[:cntrl:]` - Control characters, equivalent to `[\\x00-\\x1F\\x7F]`.
+* `[:digit:]` - Numerical digits, equivalent to `[0-9]`.
+* `[:graph:]` - Graph characters, equivalent to `[\\x21-\\x7E]`.
+* `[:lower:]` - Lowercase letters, equivalent to `[a-z]`.
+* `[:print:]` - Print characters, equivalent to `[\\x20-\\x7E ]`.
+* `[:punct:]` - Punctuation and symbols, equivalent to `[\\-!"#$%&\'()\\*+,./:;<=>?@[\\]^_`{|}~]`.
+* `[:space:]` - Extended space characters, equivalent to `[ \\t\\r\\n\\v\\f]`.
+* `[:upper:]` - Uppercase letters, equivalent to `[A-Z]`.
+* `[:word:]` -  Word characters (letters, numbers and underscores), equivalent to `[A-Za-z0-9_]`.
+* `[:xdigit:]` - Hexadecimal digits, equivalent to `[A-Fa-f0-9]`.
+
+See the [Bash Reference Manual](https://www.gnu.org/software/bash/manual/html_node/Pattern-Matching.html) for more information.
+
+### Braces
+
+Picomatch does not do brace expansion. For [brace expansion](https://www.gnu.org/software/bash/manual/html_node/Brace-Expansion.html) and advanced matching with braces, use [micromatch](https://github.com/micromatch/micromatch) instead. Picomatch has very basic support for braces.
+
+### Matching special characters as literals
+
+If you wish to match the following special characters in a filepath, and you want to use these characters in your glob pattern, they must be escaped with backslashes or quotes:
+
+**Special Characters**
+
+Some characters that are used for matching in regular expressions are also regarded as valid file path characters on some platforms.
+
+To match any of the following characters as literals: `$^*+?()[]
+
+Examples:
+
+```js
+console.log(pm.makeRe('foo/bar \\(1\\)'));
+console.log(pm.makeRe('foo/bar \\(1\\)'));
+```

+
+## Philosophies
+
+The goal of this library is to be blazing fast, without compromising on accuracy.
+
+**Accuracy**
+
+The number one of goal of this library is accuracy. However, it's not unusual for different glob implementations to have different rules for matching behavior, even with simple wildcard matching. It gets increasingly more complicated when combinations of different features are combined, like when extglobs are combined with globstars, braces, slashes, and so on: `!(**/{a,b,*/c})`.
+
+Thus, given that there is no canonical glob specification to use as a single source of truth when differences of opinion arise regarding behavior, sometimes we have to implement our best judgement and rely on feedback from users to make improvements.
+
+**Performance**
+
+Although this library performs well in benchmarks, and in most cases it's faster than other popular libraries we benchmarked against, we will always choose accuracy over performance. It's not helpful to anyone if our library is faster at returning the wrong answer.

-# pseudomap
-
-A thing that is a lot like ES6 `Map`, but without iterators, for use
-in environments where `for..of` syntax and `Map` are not available.
-
-If you need iterators, or just in general a more faithful polyfill to
-ES6 Maps, check out [es6-map](http://npm.im/es6-map).
-
-If you are in an environment where `Map` is supported, then that will
-be returned instead, unless `process.env.TEST_PSEUDOMAP` is set.
-
-You can use any value as keys, and any value as data.  Setting again
-with the identical key will overwrite the previous value.
-
-Internally, data is stored on an `Object.create(null)` style object.
-The key is coerced to a string to generate the key on the internal
-data-bag object.  The original key used is stored along with the data.
-
-In the event of a stringified-key collision, a new key is generated by
-appending an increasing number to the stringified-key until finding
-either the intended key or an empty spot.
-
-Note that because object traversal order of plain objects is not
-guaranteed to be identical to insertion order, the insertion order
-guarantee of `Map.prototype.forEach` is not guaranteed in this
-implementation.  However, in all versions of Node.js and V8 where this
-module works, `forEach` does traverse data in insertion order.
-
-## API
-
-Most of the [Map
-API](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Map),
-with the following exceptions:
-
-1. A `Map` object is not an iterator.
-2. `values`, `keys`, and `entries` methods are not implemented,
-   because they return iterators.
-3. The argument to the constructor can be an Array of `[key, value]`
-   pairs, or a `Map` or `PseudoMap` object.  But, since iterators
-   aren't used, passing any plain-old iterator won't initialize the
-   map properly.
-
-## USAGE
-
-Use just like a regular ES6 Map.
-
-```javascript
-var PseudoMap = require('pseudomap')
-
-// optionally provide a pseudomap, or an array of [key,value] pairs
-// as the argument to initialize the map with
-var myMap = new PseudoMap()
-
-myMap.set(1, 'number 1')
-myMap.set('1', 'string 1')
-var akey = {}
-var bkey = {}
-myMap.set(akey, { some: 'data' })
-myMap.set(bkey, { some: 'other data' })
-```

-# psl (Public Suffix List)
-
-[![NPM](https://nodei.co/npm/psl.png?downloads=true&downloadRank=true)](https://nodei.co/npm/psl/)
-
-[![Greenkeeper badge](https://badges.greenkeeper.io/lupomontero/psl.svg)](https://greenkeeper.io/)
-[![Build Status](https://travis-ci.org/lupomontero/psl.svg?branch=master)](https://travis-ci.org/lupomontero/psl)
-[![devDependency Status](https://david-dm.org/lupomontero/psl/dev-status.png)](https://david-dm.org/lupomontero/psl#info=devDependencies)
-
-`psl` is a `JavaScript` domain name parser based on the
-[Public Suffix List](https://publicsuffix.org/).
-
-This implementation is tested against the
-[test data hosted by Mozilla](http://mxr.mozilla.org/mozilla-central/source/netwerk/test/unit/data/test_psl.txt?raw=1)
-and kindly provided by [Comodo](https://www.comodo.com/).
-
-Cross browser testing provided by
-[<img alt="BrowserStack" width="160" src="./browserstack-logo.svg" />](https://www.browserstack.com/)
-
-## What is the Public Suffix List?
-
-The Public Suffix List is a cross-vendor initiative to provide an accurate list
-of domain name suffixes.
-
-The Public Suffix List is an initiative of the Mozilla Project, but is
-maintained as a community resource. It is available for use in any software,
-but was originally created to meet the needs of browser manufacturers.
-
-A "public suffix" is one under which Internet users can directly register names.
-Some examples of public suffixes are ".com", ".co.uk" and "pvt.k12.wy.us". The
-Public Suffix List is a list of all known public suffixes.
-
-Source: http://publicsuffix.org
-
-
-## Installation
-
-### Node.js
-
-```sh
-npm install --save psl
-```
-
-### Browser
-
-Download [psl.min.js](https://raw.githubusercontent.com/lupomontero/psl/master/dist/psl.min.js)
-and include it in a script tag.
-
-```html
-<script src="psl.min.js"></script>
-```
-
-This script is browserified and wrapped in a [umd](https://github.com/umdjs/umd)
-wrapper so you should be able to use it standalone or together with a module
-loader.
-
-## API
-
-### `psl.parse(domain)`
-
-Parse domain based on Public Suffix List. Returns an `Object` with the following
-properties:
-
-* `tld`: Top level domain (this is the _public suffix_).
-* `sld`: Second level domain (the first private part of the domain name).
-* `domain`: The domain name is the `sld` + `tld`.
-* `subdomain`: Optional parts left of the domain.
-
-#### Example:
-
-```js
-var psl = require('psl');
-
-// Parse domain without subdomain
-var parsed = psl.parse('google.com');
-console.log(parsed.tld); // 'com'
-console.log(parsed.sld); // 'google'
-console.log(parsed.domain); // 'google.com'
-console.log(parsed.subdomain); // null
-
-// Parse domain with subdomain
-var parsed = psl.parse('www.google.com');
-console.log(parsed.tld); // 'com'
-console.log(parsed.sld); // 'google'
-console.log(parsed.domain); // 'google.com'
-console.log(parsed.subdomain); // 'www'
-
-// Parse domain with nested subdomains
-var parsed = psl.parse('a.b.c.d.foo.com');
-console.log(parsed.tld); // 'com'
-console.log(parsed.sld); // 'foo'
-console.log(parsed.domain); // 'foo.com'
-console.log(parsed.subdomain); // 'a.b.c.d'
-```
-
-### `psl.get(domain)`
-
-Get domain name, `sld` + `tld`. Returns `null` if not valid.
-
-#### Example:
-
-```js
-var psl = require('psl');
-
-// null input.
-psl.get(null); // null
-
-// Mixed case.
-psl.get('COM'); // null
-psl.get('example.COM'); // 'example.com'
-psl.get('WwW.example.COM'); // 'example.com'
-
-// Unlisted TLD.
-psl.get('example'); // null
-psl.get('example.example'); // 'example.example'
-psl.get('b.example.example'); // 'example.example'
-psl.get('a.b.example.example'); // 'example.example'
-
-// TLD with only 1 rule.
-psl.get('biz'); // null
-psl.get('domain.biz'); // 'domain.biz'
-psl.get('b.domain.biz'); // 'domain.biz'
-psl.get('a.b.domain.biz'); // 'domain.biz'
-
-// TLD with some 2-level rules.
-psl.get('uk.com'); // null);
-psl.get('example.uk.com'); // 'example.uk.com');
-psl.get('b.example.uk.com'); // 'example.uk.com');
-
-// More complex TLD.
-psl.get('c.kobe.jp'); // null
-psl.get('b.c.kobe.jp'); // 'b.c.kobe.jp'
-psl.get('a.b.c.kobe.jp'); // 'b.c.kobe.jp'
-psl.get('city.kobe.jp'); // 'city.kobe.jp'
-psl.get('www.city.kobe.jp'); // 'city.kobe.jp'
-
-// IDN labels.
-psl.get('食狮.com.cn'); // '食狮.com.cn'
-psl.get('食狮.公司.cn'); // '食狮.公司.cn'
-psl.get('www.食狮.公司.cn'); // '食狮.公司.cn'
-
-// Same as above, but punycoded.
-psl.get('xn--85x722f.com.cn'); // 'xn--85x722f.com.cn'
-psl.get('xn--85x722f.xn--55qx5d.cn'); // 'xn--85x722f.xn--55qx5d.cn'
-psl.get('www.xn--85x722f.xn--55qx5d.cn'); // 'xn--85x722f.xn--55qx5d.cn'
-```
-
-### `psl.isValid(domain)`
-
-Check whether a domain has a valid Public Suffix. Returns a `Boolean` indicating
-whether the domain has a valid Public Suffix.
-
-#### Example
-
-```js
-var psl = require('psl');
-
-psl.isValid('google.com'); // true
-psl.isValid('www.google.com'); // true
-psl.isValid('x.yz'); // false
-```
-
-
-## Testing and Building
-
-Test are written using [`mocha`](https://mochajs.org/) and can be
-run in two different environments: `node` and `phantomjs`.
-
-```sh
-# This will run `eslint`, `mocha` and `karma`.
-npm test
-
-# Individual test environments
-# Run tests in node only.
-./node_modules/.bin/mocha test
-# Run tests in phantomjs only.
-./node_modules/.bin/karma start ./karma.conf.js --single-run
-
-# Build data (parse raw list) and create dist files
-npm run build
-```
-
-Feel free to fork if you see possible improvements!

-# Punycode.js [![Build status](https://travis-ci.org/bestiejs/punycode.js.svg?branch=master)](https://travis-ci.org/bestiejs/punycode.js) [![Code coverage status](http://img.shields.io/codecov/c/github/bestiejs/punycode.js.svg)](https://codecov.io/gh/bestiejs/punycode.js) [![Dependency status](https://gemnasium.com/bestiejs/punycode.js.svg)](https://gemnasium.com/bestiejs/punycode.js)
-
-Punycode.js is a robust Punycode converter that fully complies to [RFC 3492](https://tools.ietf.org/html/rfc3492) and [RFC 5891](https://tools.ietf.org/html/rfc5891).
-
-This JavaScript library is the result of comparing, optimizing and documenting different open-source implementations of the Punycode algorithm:
-
-* [The C example code from RFC 3492](https://tools.ietf.org/html/rfc3492#appendix-C)
-* [`punycode.c` by _Markus W. Scherer_ (IBM)](http://opensource.apple.com/source/ICU/ICU-400.42/icuSources/common/punycode.c)
-* [`punycode.c` by _Ben Noordhuis_](https://github.com/bnoordhuis/punycode/blob/master/punycode.c)
-* [JavaScript implementation by _some_](http://stackoverflow.com/questions/183485/can-anyone-recommend-a-good-free-javascript-for-punycode-to-unicode-conversion/301287#301287)
-* [`punycode.js` by _Ben Noordhuis_](https://github.com/joyent/node/blob/426298c8c1c0d5b5224ac3658c41e7c2a3fe9377/lib/punycode.js) (note: [not fully compliant](https://github.com/joyent/node/issues/2072))
-
-This project was [bundled](https://github.com/joyent/node/blob/master/lib/punycode.js) with Node.js from [v0.6.2+](https://github.com/joyent/node/compare/975f1930b1...61e796decc) until [v7](https://github.com/nodejs/node/pull/7941) (soft-deprecated).
-
-The current version supports recent versions of Node.js only. It provides a CommonJS module and an ES6 module. For the old version that offers the same functionality with broader support, including Rhino, Ringo, Narwhal, and web browsers, see [v1.4.1](https://github.com/bestiejs/punycode.js/releases/tag/v1.4.1).
-
-## Installation
-
-Via [npm](https://www.npmjs.com/):
-
-```bash
-npm install punycode --save
-```
-
-In [Node.js](https://nodejs.org/):
-
-```js
-const punycode = require('punycode');
-```
-
-## API
-
-### `punycode.decode(string)`
-
-Converts a Punycode string of ASCII symbols to a string of Unicode symbols.
-
-```js
-// decode domain name parts
-punycode.decode('maana-pta'); // 'mañana'
-punycode.decode('--dqo34k'); // '☃-⌘'
-```
-
-### `punycode.encode(string)`
-
-Converts a string of Unicode symbols to a Punycode string of ASCII symbols.
-
-```js
-// encode domain name parts
-punycode.encode('mañana'); // 'maana-pta'
-punycode.encode('☃-⌘'); // '--dqo34k'
-```
-
-### `punycode.toUnicode(input)`
-
-Converts a Punycode string representing a domain name or an email address to Unicode. Only the Punycoded parts of the input will be converted, i.e. it doesn’t matter if you call it on a string that has already been converted to Unicode.
-
-```js
-// decode domain names
-punycode.toUnicode('xn--maana-pta.com');
-// → 'mañana.com'
-punycode.toUnicode('xn----dqo34k.com');
-// → '☃-⌘.com'

-// decode email addresses
-punycode.toUnicode('джумла@xn--p-8sbkgc5ag7bhce.xn--ba-lmcq');
-// → 'джумла@джpумлатест.bрфa'
-```
-
-### `punycode.toASCII(input)`
-
-Converts a lowercased Unicode string representing a domain name or an email address to Punycode. Only the non-ASCII parts of the input will be converted, i.e. it doesn’t matter if you call it with a domain that’s already in ASCII.
-
-```js
-// encode domain names
-punycode.toASCII('mañana.com');
-// → 'xn--maana-pta.com'
-punycode.toASCII('☃-⌘.com');
-// → 'xn----dqo34k.com'
-
-// encode email addresses
-punycode.toASCII('джумла@джpумлатест.bрфa');
-// → 'джумла@xn--p-8sbkgc5ag7bhce.xn--ba-lmcq'
-```
-
-### `punycode.ucs2`
-
-#### `punycode.ucs2.decode(string)`
-
-Creates an array containing the numeric code point values of each Unicode symbol in the string. While [JavaScript uses UCS-2 internally](https://mathiasbynens.be/notes/javascript-encoding), this function will convert a pair of surrogate halves (each of which UCS-2 exposes as separate characters) into a single code point, matching UTF-16.
-
-```js
-punycode.ucs2.decode('abc');
-// → [0x61, 0x62, 0x63]
-// surrogate pair for U+1D306 TETRAGRAM FOR CENTRE:
-punycode.ucs2.decode('\uD834\uDF06');
-// → [0x1D306]
-```
-
-#### `punycode.ucs2.encode(codePoints)`
-
-Creates a string based on an array of numeric code point values.
-
-```js
-punycode.ucs2.encode([0x61, 0x62, 0x63]);
-// → 'abc'
-punycode.ucs2.encode([0x1D306]);
-// → '\uD834\uDF06'
-```
-
-### `punycode.version`
-
-A string representing the current Punycode.js version number.

-
-A querystring parsing and stringifying library with some added security.
-
-Lead Maintainer: [Jordan Harband](https://github.com/ljharb)
-
-The **qs** module was originally created and maintained by [TJ Holowaychuk](https://github.com/visionmedia/node-querystring).
-
-## Usage
-
-```javascript
-var qs = require('qs');
-var assert = require('assert');
-
-var obj = qs.parse('a=c');
-assert.deepEqual(obj, { a: 'c' });
-
-var str = qs.stringify(obj);
-assert.equal(str, 'a=c');
-```
-
-### Parsing Objects
-
-[](#preventEval)
-```javascript
-qs.parse(string, [options]);
-```
-
-**qs** allows you to create nested objects within your query strings, by surrounding the name of sub-keys with square brackets `[]`.
-For example, the string `'foo[bar]=baz'` converts to:
-
-```javascript
-assert.deepEqual(qs.parse('foo[bar]=baz'), {
-    foo: {
-        bar: 'baz'
-    }
-});
-```
-
-When using the `plainObjects` option the parsed value is returned as a null object, created via `Object.create(null)` and as such you should be aware that prototype methods will not exist on it and a user may set those names to whatever value they like:
-
-```javascript
-var nullObject = qs.parse('a[hasOwnProperty]=b', { plainObjects: true });
-assert.deepEqual(nullObject, { a: { hasOwnProperty: 'b' } });
-```
-
-By default parameters that would overwrite properties on the object prototype are ignored, if you wish to keep the data from those fields either use `plainObjects` as mentioned above, or set `allowPrototypes` to `true` which will allow user input to overwrite those properties. *WARNING* It is generally a bad idea to enable this option as it can cause problems when attempting to use the properties that have been overwritten. Always be careful with this option.
-
-```javascript
-var protoObject = qs.parse('a[hasOwnProperty]=b', { allowPrototypes: true });
-assert.deepEqual(protoObject, { a: { hasOwnProperty: 'b' } });
-```
-
-URI encoded strings work too:
-
-```javascript
-assert.deepEqual(qs.parse('a%5Bb%5D=c'), {
-    a: { b: 'c' }
-});
-```
-
-You can also nest your objects, like `'foo[bar][baz]=foobarbaz'`:
-
-```javascript
-assert.deepEqual(qs.parse('foo[bar][baz]=foobarbaz'), {
-    foo: {
-        bar: {
-            baz: 'foobarbaz'
-        }
-    }
-});
-```
-
-By default, when nesting objects **qs** will only parse up to 5 children deep. This means if you attempt to parse a string like
-`'a[b][c][d][e][f][g][h][i]=j'` your resulting object will be:
-
-```javascript
-var expected = {
-    a: {
-        b: {
-            c: {
-                d: {
-                    e: {
-                        f: {
-                            '[g][h][i]': 'j'
-                        }
-                    }
-                }
-            }
-        }
-    }
-};
-var string = 'a[b][c][d][e][f][g][h][i]=j';
-assert.deepEqual(qs.parse(string), expected);
-```
-
-This depth can be overridden by passing a `depth` option to `qs.parse(string, [options])`:
-
-```javascript
-var deep = qs.parse('a[b][c][d][e][f][g][h][i]=j', { depth: 1 });
-assert.deepEqual(deep, { a: { b: { '[c][d][e][f][g][h][i]': 'j' } } });
-```
-
-The depth limit helps mitigate abuse when **qs** is used to parse user input, and it is recommended to keep it a reasonably small number.
-
-For similar reasons, by default **qs** will only parse up to 1000 parameters. This can be overridden by passing a `parameterLimit` option:
-
-```javascript
-var limited = qs.parse('a=b&c=d', { parameterLimit: 1 });
-assert.deepEqual(limited, { a: 'b' });
-```
-
-To bypass the leading question mark, use `ignoreQueryPrefix`:
-
-```javascript
-var prefixed = qs.parse('?a=b&c=d', { ignoreQueryPrefix: true });
-assert.deepEqual(prefixed, { a: 'b', c: 'd' });
-```
-
-An optional delimiter can also be passed:
-
-```javascript
-var delimited = qs.parse('a=b;c=d', { delimiter: ';' });
-assert.deepEqual(delimited, { a: 'b', c: 'd' });
-```
-
-Delimiters can be a regular expression too:
-
-```javascript
-var regexed = qs.parse('a=b;c=d,e=f', { delimiter: /[;,]/ });
-assert.deepEqual(regexed, { a: 'b', c: 'd', e: 'f' });
-```
-
-Option `allowDots` can be used to enable dot notation:
-
-```javascript
-var withDots = qs.parse('a.b=c', { allowDots: true });
-assert.deepEqual(withDots, { a: { b: 'c' } });
-```
-
-### Parsing Arrays
-
-**qs** can also parse arrays using a similar `[]` notation:
-
-```javascript
-var withArray = qs.parse('a[]=b&a[]=c');
-assert.deepEqual(withArray, { a: ['b', 'c'] });
-```
-
-You may specify an index as well:
-
-```javascript
-var withIndexes = qs.parse('a[1]=c&a[0]=b');
-assert.deepEqual(withIndexes, { a: ['b', 'c'] });
-```
-
-Note that the only difference between an index in an array and a key in an object is that the value between the brackets must be a number
-to create an array. When creating arrays with specific indices, **qs** will compact a sparse array to only the existing values preserving
-their order:
-
-```javascript
-var noSparse = qs.parse('a[1]=b&a[15]=c');
-assert.deepEqual(noSparse, { a: ['b', 'c'] });
-```
-
-Note that an empty string is also a value, and will be preserved:
-
-```javascript
-var withEmptyString = qs.parse('a[]=&a[]=b');
-assert.deepEqual(withEmptyString, { a: ['', 'b'] });
-
-var withIndexedEmptyString = qs.parse('a[0]=b&a[1]=&a[2]=c');
-assert.deepEqual(withIndexedEmptyString, { a: ['b', '', 'c'] });
-```
-
-**qs** will also limit specifying indices in an array to a maximum index of `20`. Any array members with an index of greater than `20` will
-instead be converted to an object with the index as the key:
-
-```javascript
-var withMaxIndex = qs.parse('a[100]=b');
-assert.deepEqual(withMaxIndex, { a: { '100': 'b' } });
-```
-
-This limit can be overridden by passing an `arrayLimit` option:
-
-```javascript
-var withArrayLimit = qs.parse('a[1]=b', { arrayLimit: 0 });
-assert.deepEqual(withArrayLimit, { a: { '1': 'b' } });
-```
-
-To disable array parsing entirely, set `parseArrays` to `false`.
-
-```javascript
-var noParsingArrays = qs.parse('a[]=b', { parseArrays: false });
-assert.deepEqual(noParsingArrays, { a: { '0': 'b' } });
-```
-
-If you mix notations, **qs** will merge the two items into an object:
-
-```javascript
-var mixedNotation = qs.parse('a[0]=b&a[b]=c');
-assert.deepEqual(mixedNotation, { a: { '0': 'b', b: 'c' } });
-```
-
-You can also create arrays of objects:
-
-```javascript
-var arraysOfObjects = qs.parse('a[][b]=c');
-assert.deepEqual(arraysOfObjects, { a: [{ b: 'c' }] });
-```
-
-### Stringifying
-
-[](#preventEval)
-```javascript
-qs.stringify(object, [options]);
-```
-
-When stringifying, **qs** by default URI encodes output. Objects are stringified as you would expect:
-
-```javascript
-assert.equal(qs.stringify({ a: 'b' }), 'a=b');
-assert.equal(qs.stringify({ a: { b: 'c' } }), 'a%5Bb%5D=c');
-```
-
-This encoding can be disabled by setting the `encode` option to `false`:
-
-```javascript
-var unencoded = qs.stringify({ a: { b: 'c' } }, { encode: false });
-assert.equal(unencoded, 'a[b]=c');
-```
-
-Encoding can be disabled for keys by setting the `encodeValuesOnly` option to `true`:
-```javascript
-var encodedValues = qs.stringify(
-    { a: 'b', c: ['d', 'e=f'], f: [['g'], ['h']] },
-    { encodeValuesOnly: true }
-);
-assert.equal(encodedValues,'a=b&c[0]=d&c[1]=e%3Df&f[0][0]=g&f[1][0]=h');
-```
-
-This encoding can also be replaced by a custom encoding method set as `encoder` option:
-
-```javascript
-var encoded = qs.stringify({ a: { b: 'c' } }, { encoder: function (str) {
-    // Passed in values `a`, `b`, `c`
-    return // Return encoded string
-}})
-```
-
-_(Note: the `encoder` option does not apply if `encode` is `false`)_
-
-Analogue to the `encoder` there is a `decoder` option for `parse` to override decoding of properties and values:
-
-```javascript
-var decoded = qs.parse('x=z', { decoder: function (str) {
-    // Passed in values `x`, `z`
-    return // Return decoded string
-}})
-```
-
-Examples beyond this point will be shown as though the output is not URI encoded for clarity. Please note that the return values in these cases *will* be URI encoded during real usage.
-
-When arrays are stringified, by default they are given explicit indices:
-
-```javascript
-qs.stringify({ a: ['b', 'c', 'd'] });
-// 'a[0]=b&a[1]=c&a[2]=d'
-```
-
-You may override this by setting the `indices` option to `false`:
-
-```javascript
-qs.stringify({ a: ['b', 'c', 'd'] }, { indices: false });
-// 'a=b&a=c&a=d'
-```
-
-You may use the `arrayFormat` option to specify the format of the output array:
-
-```javascript
-qs.stringify({ a: ['b', 'c'] }, { arrayFormat: 'indices' })
-// 'a[0]=b&a[1]=c'
-qs.stringify({ a: ['b', 'c'] }, { arrayFormat: 'brackets' })
-// 'a[]=b&a[]=c'
-qs.stringify({ a: ['b', 'c'] }, { arrayFormat: 'repeat' })
-// 'a=b&a=c'
-```
-
-When objects are stringified, by default they use bracket notation:
-
-```javascript
-qs.stringify({ a: { b: { c: 'd', e: 'f' } } });
-// 'a[b][c]=d&a[b][e]=f'
-```
-
-You may override this to use dot notation by setting the `allowDots` option to `true`:
-
-```javascript
-qs.stringify({ a: { b: { c: 'd', e: 'f' } } }, { allowDots: true });
-// 'a.b.c=d&a.b.e=f'
-```
-
-Empty strings and null values will omit the value, but the equals sign (=) remains in place:
-
-```javascript
-assert.equal(qs.stringify({ a: '' }), 'a=');
-```
-
-Key with no values (such as an empty object or array) will return nothing:
-
-```javascript
-assert.equal(qs.stringify({ a: [] }), '');
-assert.equal(qs.stringify({ a: {} }), '');
-assert.equal(qs.stringify({ a: [{}] }), '');
-assert.equal(qs.stringify({ a: { b: []} }), '');
-assert.equal(qs.stringify({ a: { b: {}} }), '');
-```
-
-Properties that are set to `undefined` will be omitted entirely:
-
-```javascript
-assert.equal(qs.stringify({ a: null, b: undefined }), 'a=');
-```
-
-The query string may optionally be prepended with a question mark:
-
-```javascript
-assert.equal(qs.stringify({ a: 'b', c: 'd' }, { addQueryPrefix: true }), '?a=b&c=d');
-```
-
-The delimiter may be overridden with stringify as well:
-
-```javascript
-assert.equal(qs.stringify({ a: 'b', c: 'd' }, { delimiter: ';' }), 'a=b;c=d');
-```
-
-If you only want to override the serialization of `Date` objects, you can provide a `serializeDate` option:
-
-```javascript
-var date = new Date(7);
-assert.equal(qs.stringify({ a: date }), 'a=1970-01-01T00:00:00.007Z'.replace(/:/g, '%3A'));
-assert.equal(
-    qs.stringify({ a: date }, { serializeDate: function (d) { return d.getTime(); } }),
-    'a=7'
-);
-```
-
-You may use the `sort` option to affect the order of parameter keys:
-
-```javascript
-function alphabeticalSort(a, b) {
-    return a.localeCompare(b);
-}
-assert.equal(qs.stringify({ a: 'c', z: 'y', b : 'f' }, { sort: alphabeticalSort }), 'a=c&b=f&z=y');
-```
-
-Finally, you can use the `filter` option to restrict which keys will be included in the stringified output.
-If you pass a function, it will be called for each key to obtain the replacement value. Otherwise, if you
-pass an array, it will be used to select properties and array indices for stringification:
-
-```javascript
-function filterFunc(prefix, value) {
-    if (prefix == 'b') {
-        // Return an `undefined` value to omit a property.
-        return;
-    }
-    if (prefix == 'e[f]') {
-        return value.getTime();
-    }
-    if (prefix == 'e[g][0]') {
-        return value * 2;
-    }
-    return value;
-}
-qs.stringify({ a: 'b', c: 'd', e: { f: new Date(123), g: [2] } }, { filter: filterFunc });
-// 'a=b&c=d&e[f]=123&e[g][0]=4'
-qs.stringify({ a: 'b', c: 'd', e: 'f' }, { filter: ['a', 'e'] });
-// 'a=b&e=f'
-qs.stringify({ a: ['b', 'c', 'd'], e: 'f' }, { filter: ['a', 0, 2] });
-// 'a[0]=b&a[2]=d'
-```
-
-### Handling of `null` values
-
-By default, `null` values are treated like empty strings:
-
-```javascript
-var withNull = qs.stringify({ a: null, b: '' });
-assert.equal(withNull, 'a=&b=');
-```
-
-Parsing does not distinguish between parameters with and without equal signs. Both are converted to empty strings.
-
-```javascript
-var equalsInsensitive = qs.parse('a&b=');
-assert.deepEqual(equalsInsensitive, { a: '', b: '' });
-```
-
-To distinguish between `null` values and empty strings use the `strictNullHandling` flag. In the result string the `null`
-values have no `=` sign:
-
-```javascript
-var strictNull = qs.stringify({ a: null, b: '' }, { strictNullHandling: true });
-assert.equal(strictNull, 'a&b=');
-```
-
-To parse values without `=` back to `null` use the `strictNullHandling` flag:
-
-```javascript
-var parsedStrictNull = qs.parse('a&b=', { strictNullHandling: true });
-assert.deepEqual(parsedStrictNull, { a: null, b: '' });
-```
-
-To completely skip rendering keys with `null` values, use the `skipNulls` flag:
-
-```javascript
-var nullsSkipped = qs.stringify({ a: 'b', c: null}, { skipNulls: true });
-assert.equal(nullsSkipped, 'a=b');
-```
-
-### Dealing with special character sets
-
-By default the encoding and decoding of characters is done in `utf-8`. If you
-wish to encode querystrings to a different character set (i.e.
-[Shift JIS](https://en.wikipedia.org/wiki/Shift_JIS)) you can use the
-[`qs-iconv`](https://github.com/martinheidegger/qs-iconv) library:
-
-```javascript
-var encoder = require('qs-iconv/encoder')('shift_jis');
-var shiftJISEncoded = qs.stringify({ a: 'こんにちは！' }, { encoder: encoder });
-assert.equal(shiftJISEncoded, 'a=%82%B1%82%F1%82%C9%82%BF%82%CD%81I');
-```
-
-This also works for decoding of query strings:
-
-```javascript
-var decoder = require('qs-iconv/decoder')('shift_jis');
-var obj = qs.parse('a=%82%B1%82%F1%82%C9%82%BF%82%CD%81I', { decoder: decoder });
-assert.deepEqual(obj, { a: 'こんにちは！' });
-```
-
-### RFC 3986 and RFC 1738 space encoding
-
-RFC3986 used as default option and encodes ' ' to *%20* which is backward compatible.
-In the same time, output can be stringified as per RFC1738 with ' ' equal to '+'.
-

-## Super simple to use
-
-Request is designed to be the simplest way possible to make http calls. It supports HTTPS and follows redirects by default.
-
-```js
-var request = require('request');
-request('http://www.google.com', function (error, response, body) {
-  console.log('error:', error); // Print the error if one occurred
-  console.log('statusCode:', response && response.statusCode); // Print the response status code if a response was received
-  console.log('body:', body); // Print the HTML for the Google homepage.
-});
-```

-`request.defaults` and `request.post`, and there are
-lots of [usage examples](#examples) and several
-[debugging techniques](#debugging).
-
-
----
-
-
-## Streaming
-
-You can stream any response to a file stream.
-
-```js
-request('http://google.com/doodle.png').pipe(fs.createWriteStream('doodle.png'))
-```
-
-You can also stream a file to a PUT or POST request. This method will also check the file extension against a mapping of file extensions to content-types (in this case `application/json`) and use the proper `content-type` in the PUT request (if the headers don’t already provide one).
-
-```js
-fs.createReadStream('file.json').pipe(request.put('http://mysite.com/obj.json'))
-```
-
-Request can also `pipe` to itself. When doing so, `content-type` and `content-length` are preserved in the PUT headers.
-
-```js
-request.get('http://google.com/img.png').pipe(request.put('http://mysite.com/img.png'))
-```
-
-Request emits a "response" event when a response is received. The `response` argument will be an instance of [http.IncomingMessage](https://nodejs.org/api/http.html#http_class_http_incomingmessage).
-
-```js
-request
-  .get('http://google.com/img.png')
-  .on('response', function(response) {
-    console.log(response.statusCode) // 200
-    console.log(response.headers['content-type']) // 'image/png'
-  })
-  .pipe(request.put('http://mysite.com/img.png'))
-```
-
-To easily handle errors when streaming requests, listen to the `error` event before piping:
-
-```js
-request
-  .get('http://mysite.com/doodle.png')
-  .on('error', function(err) {
-    console.log(err)
-  })
-  .pipe(fs.createWriteStream('doodle.png'))
-```
-
-Now let’s get fancy.
-
-```js
-http.createServer(function (req, resp) {
-  if (req.url === '/doodle.png') {
-    if (req.method === 'PUT') {
-      req.pipe(request.put('http://mysite.com/doodle.png'))
-    } else if (req.method === 'GET' || req.method === 'HEAD') {
-      request.get('http://mysite.com/doodle.png').pipe(resp)
-    }
-  }
-})
-```
-
-You can also `pipe()` from `http.ServerRequest` instances, as well as to `http.ServerResponse` instances. The HTTP method, headers, and entity-body data will be sent. Which means that, if you don't really care about security, you can do:
-
-```js
-http.createServer(function (req, resp) {
-  if (req.url === '/doodle.png') {
-    var x = request('http://mysite.com/doodle.png')
-    req.pipe(x)
-    x.pipe(resp)
-  }
-})
-```
-
-And since `pipe()` returns the destination stream in ≥ Node 0.5.x you can do one line proxying. :)
-
-```js
-req.pipe(request('http://mysite.com/doodle.png')).pipe(resp)
-```
-
-Also, none of this new functionality conflicts with requests previous features, it just expands them.
-
-```js
-var r = request.defaults({'proxy':'http://localproxy.com'})
-
-http.createServer(function (req, resp) {
-  if (req.url === '/doodle.png') {
-    r.get('http://google.com/doodle.png').pipe(resp)
-  }
-})
-```
-
-You can still use intermediate proxies, the requests will still follow HTTP forwards, etc.

-
-
-## Promises & Async/Await
-
-`request` supports both streaming and callback interfaces natively. If you'd like `request` to return a Promise instead, you can use an alternative interface wrapper for `request`. These wrappers can be useful if you prefer to work with Promises, or if you'd like to use `async`/`await` in ES2017.
-
-Several alternative interfaces are provided by the request team, including:
-- [`request-promise`](https://github.com/request/request-promise) (uses [Bluebird](https://github.com/petkaantonov/bluebird) Promises)
-- [`request-promise-native`](https://github.com/request/request-promise-native) (uses native Promises)
-- [`request-promise-any`](https://github.com/request/request-promise-any) (uses [any-promise](https://www.npmjs.com/package/any-promise) Promises)
-

-
-
-## Forms
-
-`request` supports `application/x-www-form-urlencoded` and `multipart/form-data` form uploads. For `multipart/related` refer to the `multipart` API.
-
-
-#### application/x-www-form-urlencoded (URL-Encoded Forms)
-
-URL-encoded forms are simple.
-
-```js
-request.post('http://service.com/upload', {form:{key:'value'}})
-// or
-request.post('http://service.com/upload').form({key:'value'})
-// or
-request.post({url:'http://service.com/upload', form: {key:'value'}}, function(err,httpResponse,body){ /* ... */ })
-```

-
-#### multipart/form-data (Multipart Form Uploads)
-
-For `multipart/form-data` we use the [form-data](https://github.com/form-data/form-data) library by [@felixge](https://github.com/felixge). For the most cases, you can pass your upload form data via the `formData` option.
-
-
-```js
-var formData = {
-  // Pass a simple key-value pair
-  my_field: 'my_value',
-  // Pass data via Buffers
-  my_buffer: Buffer.from([1, 2, 3]),
-  // Pass data via Streams
-  my_file: fs.createReadStream(__dirname + '/unicycle.jpg'),
-  // Pass multiple values /w an Array
-  attachments: [
-    fs.createReadStream(__dirname + '/attachment1.jpg'),
-    fs.createReadStream(__dirname + '/attachment2.jpg')
-  ],
-  // Pass optional meta-data with an 'options' object with style: {value: DATA, options: OPTIONS}
-  // Use case: for some types of streams, you'll need to provide "file"-related information manually.
-  // See the `form-data` README for more information about options: https://github.com/form-data/form-data
-  custom_file: {
-    value:  fs.createReadStream('/dev/urandom'),
-    options: {
-      filename: 'topsecret.jpg',
-      contentType: 'image/jpeg'
-    }
-  }
-};
-request.post({url:'http://service.com/upload', formData: formData}, function optionalCallback(err, httpResponse, body) {
-  if (err) {
-    return console.error('upload failed:', err);
-  }
-  console.log('Upload successful!  Server responded with:', body);
-});
-```
-
-For advanced cases, you can access the form-data object itself via `r.form()`. This can be modified until the request is fired on the next cycle of the event-loop. (Note that this calling `form()` will clear the currently set form data for that request.)
-
-```js
-// NOTE: Advanced use-case, for normal use see 'formData' usage above
-var r = request.post('http://service.com/upload', function optionalCallback(err, httpResponse, body) {...})
-var form = r.form();
-form.append('my_field', 'my_value');
-form.append('my_buffer', Buffer.from([1, 2, 3]));
-form.append('custom_file', fs.createReadStream(__dirname + '/unicycle.jpg'), {filename: 'unicycle.jpg'});
-```
-See the [form-data README](https://github.com/form-data/form-data) for more information & examples.
-
-
-#### multipart/related
-
-Some variations in different HTTP implementations require a newline/CRLF before, after, or both before and after the boundary of a `multipart/related` request (using the multipart option). This has been observed in the .NET WebAPI version 4.0. You can turn on a boundary preambleCRLF or postamble by passing them as `true` to your request options.
-
-```js
-  request({
-    method: 'PUT',
-    preambleCRLF: true,
-    postambleCRLF: true,
-    uri: 'http://service.com/upload',
-    multipart: [
-      {
-        'content-type': 'application/json',
-        body: JSON.stringify({foo: 'bar', _attachments: {'message.txt': {follows: true, length: 18, 'content_type': 'text/plain' }}})
-      },
-      { body: 'I am an attachment' },
-      { body: fs.createReadStream('image.png') }
-    ],
-    // alternatively pass an object containing additional options
-    multipart: {
-      chunked: false,
-      data: [
-        {
-          'content-type': 'application/json',
-          body: JSON.stringify({foo: 'bar', _attachments: {'message.txt': {follows: true, length: 18, 'content_type': 'text/plain' }}})
-        },
-        { body: 'I am an attachment' }
-      ]
-    }
-  },
-  function (error, response, body) {
-    if (error) {
-      return console.error('upload failed:', error);
-    }
-    console.log('Upload successful!  Server responded with:', body);
-  })

-## HTTP Authentication
-
-```js
-request.get('http://some.server.com/').auth('username', 'password', false);
-// or
-request.get('http://some.server.com/', {
-  'auth': {
-    'user': 'username',
-    'pass': 'password',
-    'sendImmediately': false
-  }
-});
-// or
-request.get('http://some.server.com/').auth(null, null, true, 'bearerToken');
-// or
-request.get('http://some.server.com/', {
-  'auth': {
-    'bearer': 'bearerToken'
-  }
-});
-```
-
-If passed as an option, `auth` should be a hash containing values:
-
-- `user` || `username`
-- `pass` || `password`
-- `sendImmediately` (optional)
-- `bearer` (optional)
-
-The method form takes parameters
-`auth(username, password, sendImmediately, bearer)`.
-
-`sendImmediately` defaults to `true`, which causes a basic or bearer
-authentication header to be sent. If `sendImmediately` is `false`, then
-`request` will retry with a proper authentication header after receiving a
-`401` response from the server (which must contain a `WWW-Authenticate` header
-indicating the required authentication method).
-
-Note that you can also specify basic authentication using the URL itself, as
-detailed in [RFC 1738](http://www.ietf.org/rfc/rfc1738.txt). Simply pass the
-`user:password` before the host with an `@` sign:
-
-```js
-var username = 'username',
-    password = 'password',
-    url = 'http://' + username + ':' + password + '@some.server.com';
-
-request({url: url}, function (error, response, body) {
-   // Do more stuff with 'body' here
-});
-```
-
-Digest authentication is supported, but it only works with `sendImmediately`
-set to `false`; otherwise `request` will send basic authentication on the
-initial request, which will probably cause the request to fail.
-
-Bearer authentication is supported, and is activated when the `bearer` value is
-available. The value may be either a `String` or a `Function` returning a
-`String`. Using a function to supply the bearer token is particularly useful if
-used in conjunction with `defaults` to allow a single function to supply the
-last known token at the time of sending a request, or to compute one on the fly.

-## Custom HTTP Headers
-
-HTTP Headers, such as `User-Agent`, can be set in the `options` object.
-In the example below, we call the github API to find out the number
-of stars and forks for the request repository. This requires a
-custom `User-Agent` header as well as https.
-
-```js
-var request = require('request');
-
-var options = {
-  url: 'https://api.github.com/repos/request/request',
-  headers: {
-    'User-Agent': 'request'
-  }
-};
-
-function callback(error, response, body) {
-  if (!error && response.statusCode == 200) {
-    var info = JSON.parse(body);
-    console.log(info.stargazers_count + " Stars");
-    console.log(info.forks_count + " Forks");
-  }
-}

-request(options, callback);

-## OAuth Signing
-
-[OAuth version 1.0](https://tools.ietf.org/html/rfc5849) is supported. The
-default signing algorithm is
-[HMAC-SHA1](https://tools.ietf.org/html/rfc5849#section-3.4.2):
-
-```js
-// OAuth1.0 - 3-legged server side flow (Twitter example)
-// step 1
-var qs = require('querystring')
-  , oauth =
-    { callback: 'http://mysite.com/callback/'
-    , consumer_key: CONSUMER_KEY
-    , consumer_secret: CONSUMER_SECRET
-    }
-  , url = 'https://api.twitter.com/oauth/request_token'
-  ;
-request.post({url:url, oauth:oauth}, function (e, r, body) {
-  // Ideally, you would take the body in the response
-  // and construct a URL that a user clicks on (like a sign in button).
-  // The verifier is only available in the response after a user has
-  // verified with twitter that they are authorizing your app.
-
-  // step 2
-  var req_data = qs.parse(body)
-  var uri = 'https://api.twitter.com/oauth/authenticate'
-    + '?' + qs.stringify({oauth_token: req_data.oauth_token})
-  // redirect the user to the authorize uri
-
-  // step 3
-  // after the user is redirected back to your server
-  var auth_data = qs.parse(body)
-    , oauth =
-      { consumer_key: CONSUMER_KEY
-      , consumer_secret: CONSUMER_SECRET
-      , token: auth_data.oauth_token
-      , token_secret: req_data.oauth_token_secret
-      , verifier: auth_data.oauth_verifier
-      }
-    , url = 'https://api.twitter.com/oauth/access_token'
-    ;
-  request.post({url:url, oauth:oauth}, function (e, r, body) {
-    // ready to make signed requests on behalf of the user
-    var perm_data = qs.parse(body)
-      , oauth =
-        { consumer_key: CONSUMER_KEY
-        , consumer_secret: CONSUMER_SECRET
-        , token: perm_data.oauth_token
-        , token_secret: perm_data.oauth_token_secret
-        }
-      , url = 'https://api.twitter.com/1.1/users/show.json'
-      , qs =
-        { screen_name: perm_data.screen_name
-        , user_id: perm_data.user_id
-        }
-      ;
-    request.get({url:url, oauth:oauth, qs:qs, json:true}, function (e, r, user) {
-      console.log(user)
-    })
-  })
-})
-```
-
-For [RSA-SHA1 signing](https://tools.ietf.org/html/rfc5849#section-3.4.3), make
-the following changes to the OAuth options object:
-* Pass `signature_method : 'RSA-SHA1'`
-* Instead of `consumer_secret`, specify a `private_key` string in
-  [PEM format](http://how2ssl.com/articles/working_with_pem_files/)
-
-For [PLAINTEXT signing](http://oauth.net/core/1.0/#anchor22), make
-the following changes to the OAuth options object:
-* Pass `signature_method : 'PLAINTEXT'`
-
-To send OAuth parameters via query params or in a post body as described in The
-[Consumer Request Parameters](http://oauth.net/core/1.0/#consumer_req_param)
-section of the oauth1 spec:
-* Pass `transport_method : 'query'` or `transport_method : 'body'` in the OAuth
-  options object.
-* `transport_method` defaults to `'header'`
-
-To use [Request Body Hash](https://oauth.googlecode.com/svn/spec/ext/body_hash/1.0/oauth-bodyhash.html) you can either
-* Manually generate the body hash and pass it as a string `body_hash: '...'`
-* Automatically generate the body hash by passing `body_hash: true`

-## Proxies
-
-If you specify a `proxy` option, then the request (and any subsequent
-redirects) will be sent via a connection to the proxy server.
-
-If your endpoint is an `https` url, and you are using a proxy, then
-request will send a `CONNECT` request to the proxy server *first*, and
-then use the supplied connection to connect to the endpoint.
-
-That is, first it will make a request like:
-
-```
-HTTP/1.1 CONNECT endpoint-server.com:80
-Host: proxy-server.com
-User-Agent: whatever user agent you specify
-```
-
-and then the proxy server make a TCP connection to `endpoint-server`
-on port `80`, and return a response that looks like:
-
-```
-HTTP/1.1 200 OK
-```
-
-At this point, the connection is left open, and the client is
-communicating directly with the `endpoint-server.com` machine.
-
-See [the wikipedia page on HTTP Tunneling](https://en.wikipedia.org/wiki/HTTP_tunnel)
-for more information.
-
-By default, when proxying `http` traffic, request will simply make a
-standard proxied `http` request. This is done by making the `url`
-section of the initial line of the request a fully qualified url to
-the endpoint.
-
-For example, it will make a single request that looks like:
-
-```
-HTTP/1.1 GET http://endpoint-server.com/some-url
-Host: proxy-server.com
-Other-Headers: all go here
-
-request body or whatever
-```
-
-Because a pure "http over http" tunnel offers no additional security
-or other features, it is generally simpler to go with a
-straightforward HTTP proxy in this case. However, if you would like
-to force a tunneling proxy, you may set the `tunnel` option to `true`.
-
-You can also make a standard proxied `http` request by explicitly setting
-`tunnel : false`, but **note that this will allow the proxy to see the traffic
-to/from the destination server**.
-
-If you are using a tunneling proxy, you may set the
-`proxyHeaderWhiteList` to share certain headers with the proxy.
-
-You can also set the `proxyHeaderExclusiveList` to share certain
-headers only with the proxy and not with destination host.
-
-By default, this set is:
-
-```
-accept
-accept-charset
-accept-encoding
-accept-language
-accept-ranges
-cache-control
-content-encoding
-content-language
-content-length
-content-location
-content-md5
-content-range
-content-type
-connection
-date
-expect
-max-forwards
-pragma
-proxy-authorization
-referer
-te
-transfer-encoding
-user-agent
-via
-```
-
-Note that, when using a tunneling proxy, the `proxy-authorization`
-header and any headers from custom `proxyHeaderExclusiveList` are
-*never* sent to the endpoint server, but only to the proxy server.
-
-
-### Controlling proxy behaviour using environment variables
-
-The following environment variables are respected by `request`:
-
- * `HTTP_PROXY` / `http_proxy`
- * `HTTPS_PROXY` / `https_proxy`
- * `NO_PROXY` / `no_proxy`
-
-When `HTTP_PROXY` / `http_proxy` are set, they will be used to proxy non-SSL requests that do not have an explicit `proxy` configuration option present. Similarly, `HTTPS_PROXY` / `https_proxy` will be respected for SSL requests that do not have an explicit `proxy` configuration option. It is valid to define a proxy in one of the environment variables, but then override it for a specific request, using the `proxy` configuration option. Furthermore, the `proxy` configuration option can be explicitly set to false / null to opt out of proxying altogether for that request.
-
-`request` is also aware of the `NO_PROXY`/`no_proxy` environment variables. These variables provide a granular way to opt out of proxying, on a per-host basis. It should contain a comma separated list of hosts to opt out of proxying. It is also possible to opt of proxying when a particular destination port is used. Finally, the variable may be set to `*` to opt out of the implicit proxy configuration of the other environment variables.
-
-Here's some examples of valid `no_proxy` values:
-
- * `google.com` - don't proxy HTTP/HTTPS requests to Google.
- * `google.com:443` - don't proxy HTTPS requests to Google, but *do* proxy HTTP requests to Google.
- * `google.com:443, yahoo.com:80` - don't proxy HTTPS requests to Google, and don't proxy HTTP requests to Yahoo!
- * `*` - ignore `https_proxy`/`http_proxy` environment variables altogether.

-## UNIX Domain Sockets
-
-`request` supports making requests to [UNIX Domain Sockets](https://en.wikipedia.org/wiki/Unix_domain_socket). To make one, use the following URL scheme:
-
-```js
-/* Pattern */ 'http://unix:SOCKET:PATH'
-/* Example */ request.get('http://unix:/absolute/path/to/unix.socket:/request/path')
-```
-
-Note: The `SOCKET` path is assumed to be absolute to the root of the host file system.

-
-## TLS/SSL Protocol
-
-TLS/SSL Protocol options, such as `cert`, `key` and `passphrase`, can be
-set directly in `options` object, in the `agentOptions` property of the `options` object, or even in `https.globalAgent.options`. Keep in mind that, although `agentOptions` allows for a slightly wider range of configurations, the recommended way is via `options` object directly, as using `agentOptions` or `https.globalAgent.options` would not be applied in the same way in proxied environments (as data travels through a TLS connection instead of an http/https agent).
-
-```js
-var fs = require('fs')
-    , path = require('path')
-    , certFile = path.resolve(__dirname, 'ssl/client.crt')
-    , keyFile = path.resolve(__dirname, 'ssl/client.key')
-    , caFile = path.resolve(__dirname, 'ssl/ca.cert.pem')
-    , request = require('request');
-
-var options = {
-    url: 'https://api.some-server.com/',
-    cert: fs.readFileSync(certFile),
-    key: fs.readFileSync(keyFile),
-    passphrase: 'password',
-    ca: fs.readFileSync(caFile)
-};
-
-request.get(options);
-```
-
-### Using `options.agentOptions`
-
-In the example below, we call an API that requires client side SSL certificate
-(in PEM format) with passphrase protected private key (in PEM format) and disable the SSLv3 protocol:
-
-```js
-var fs = require('fs')
-    , path = require('path')
-    , certFile = path.resolve(__dirname, 'ssl/client.crt')
-    , keyFile = path.resolve(__dirname, 'ssl/client.key')
-    , request = require('request');
-
-var options = {
-    url: 'https://api.some-server.com/',
-    agentOptions: {
-        cert: fs.readFileSync(certFile),
-        key: fs.readFileSync(keyFile),
-        // Or use `pfx` property replacing `cert` and `key` when using private key, certificate and CA certs in PFX or PKCS12 format:
-        // pfx: fs.readFileSync(pfxFilePath),
-        passphrase: 'password',
-        securityOptions: 'SSL_OP_NO_SSLv3'
-    }
-};
-
-request.get(options);
-```
-
-It is able to force using SSLv3 only by specifying `secureProtocol`:
-
-```js
-request.get({
-    url: 'https://api.some-server.com/',
-    agentOptions: {
-        secureProtocol: 'SSLv3_method'
-    }
-});
-```
-
-It is possible to accept other certificates than those signed by generally allowed Certificate Authorities (CAs).
-This can be useful, for example,  when using self-signed certificates.
-To require a different root certificate, you can specify the signing CA by adding the contents of the CA's certificate file to the `agentOptions`.
-The certificate the domain presents must be signed by the root certificate specified:
-
-```js
-request.get({
-    url: 'https://api.some-server.com/',
-    agentOptions: {
-        ca: fs.readFileSync('ca.cert.pem')
-    }
-});

-## Support for HAR 1.2
-
-The `options.har` property will override the values: `url`, `method`, `qs`, `headers`, `form`, `formData`, `body`, `json`, as well as construct multipart data and read files from disk when `request.postData.params[].fileName` is present without a matching `value`.
-
-A validation step will check if the HAR Request format matches the latest spec (v1.2) and will skip parsing if not matching.
-
-```js
-  var request = require('request')
-  request({
-    // will be ignored
-    method: 'GET',
-    uri: 'http://www.google.com',

-## request(options, callback)
-
-The first argument can be either a `url` or an `options` object. The only required option is `uri`; all others are optional.
-
-- `uri` || `url` - fully qualified uri or a parsed url object from `url.parse()`
-- `baseUrl` - fully qualified uri string used as the base url. Most useful with `request.defaults`, for example when you want to do many requests to the same domain. If `baseUrl` is `https://example.com/api/`, then requesting `/end/point?test=true` will fetch `https://example.com/api/end/point?test=true`. When `baseUrl` is given, `uri` must also be a string.
-- `method` - http method (default: `"GET"`)
-- `headers` - http headers (default: `{}`)
-
----
-
-- `qs` - object containing querystring values to be appended to the `uri`
-- `qsParseOptions` - object containing options to pass to the [qs.parse](https://github.com/hapijs/qs#parsing-objects) method. Alternatively pass options to the [querystring.parse](https://nodejs.org/docs/v0.12.0/api/querystring.html#querystring_querystring_parse_str_sep_eq_options) method using this format `{sep:';', eq:':', options:{}}`
-- `qsStringifyOptions` - object containing options to pass to the [qs.stringify](https://github.com/hapijs/qs#stringifying) method. Alternatively pass options to the  [querystring.stringify](https://nodejs.org/docs/v0.12.0/api/querystring.html#querystring_querystring_stringify_obj_sep_eq_options) method using this format `{sep:';', eq:':', options:{}}`. For example, to change the way arrays are converted to query strings using the `qs` module pass the `arrayFormat` option with one of `indices|brackets|repeat`
-- `useQuerystring` - if true, use `querystring` to stringify and parse
-  querystrings, otherwise use `qs` (default: `false`). Set this option to
-  `true` if you need arrays to be serialized as `foo=bar&foo=baz` instead of the
-  default `foo[0]=bar&foo[1]=baz`.
-
----
-
-- `body` - entity body for PATCH, POST and PUT requests. Must be a `Buffer`, `String` or `ReadStream`. If `json` is `true`, then `body` must be a JSON-serializable object.
-- `form` - when passed an object or a querystring, this sets `body` to a querystring representation of value, and adds `Content-type: application/x-www-form-urlencoded` header. When passed no options, a `FormData` instance is returned (and is piped to request). See "Forms" section above.
-- `formData` - data to pass for a `multipart/form-data` request. See
-  [Forms](#forms) section above.
-- `multipart` - array of objects which contain their own headers and `body`
-  attributes. Sends a `multipart/related` request. See [Forms](#forms) section
-  above.
-  - Alternatively you can pass in an object `{chunked: false, data: []}` where
-    `chunked` is used to specify whether the request is sent in
-    [chunked transfer encoding](https://en.wikipedia.org/wiki/Chunked_transfer_encoding)
-    In non-chunked requests, data items with body streams are not allowed.
-- `preambleCRLF` - append a newline/CRLF before the boundary of your `multipart/form-data` request.
-- `postambleCRLF` - append a newline/CRLF at the end of the boundary of your `multipart/form-data` request.
-- `json` - sets `body` to JSON representation of value and adds `Content-type: application/json` header. Additionally, parses the response body as JSON.
-- `jsonReviver` - a [reviver function](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/JSON/parse) that will be passed to `JSON.parse()` when parsing a JSON response body.
-- `jsonReplacer` - a [replacer function](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/JSON/stringify) that will be passed to `JSON.stringify()` when stringifying a JSON request body.
-
----
-
-- `auth` - a hash containing values `user` || `username`, `pass` || `password`, and `sendImmediately` (optional). See documentation above.
-- `oauth` - options for OAuth HMAC-SHA1 signing. See documentation above.
-- `hawk` - options for [Hawk signing](https://github.com/hueniverse/hawk). The `credentials` key must contain the necessary signing info, [see hawk docs for details](https://github.com/hueniverse/hawk#usage-example).
-- `aws` - `object` containing AWS signing information. Should have the properties `key`, `secret`, and optionally `session` (note that this only works for services that require session as part of the canonical string). Also requires the property `bucket`, unless you’re specifying your `bucket` as part of the path, or the request doesn’t use a bucket (i.e. GET Services). If you want to use AWS sign version 4 use the parameter `sign_version` with value `4` otherwise the default is version 2. If you are using SigV4, you can also include a `service` property that specifies the service name. **Note:** you need to `npm install aws4` first.
-- `httpSignature` - options for the [HTTP Signature Scheme](https://github.com/joyent/node-http-signature/blob/master/http_signing.md) using [Joyent's library](https://github.com/joyent/node-http-signature). The `keyId` and `key` properties must be specified. See the docs for other options.
-
----
-
-- `followRedirect` - follow HTTP 3xx responses as redirects (default: `true`). This property can also be implemented as function which gets `response` object as a single argument and should return `true` if redirects should continue or `false` otherwise.
-- `followAllRedirects` - follow non-GET HTTP 3xx responses as redirects (default: `false`)
-- `followOriginalHttpMethod` - by default we redirect to HTTP method GET. you can enable this property to redirect to the original HTTP method (default: `false`)
-- `maxRedirects` - the maximum number of redirects to follow (default: `10`)
-- `removeRefererHeader` - removes the referer header when a redirect happens (default: `false`). **Note:** if true, referer header set in the initial request is preserved during redirect chain.
-
----
-
-- `encoding` - encoding to be used on `setEncoding` of response data. If `null`, the `body` is returned as a `Buffer`. Anything else **(including the default value of `undefined`)** will be passed as the [encoding](http://nodejs.org/api/buffer.html#buffer_buffer) parameter to `toString()` (meaning this is effectively `utf8` by default). (**Note:** if you expect binary data, you should set `encoding: null`.)
-- `gzip` - if `true`, add an `Accept-Encoding` header to request compressed content encodings from the server (if not already present) and decode supported content encodings in the response. **Note:** Automatic decoding of the response content is performed on the body data returned through `request` (both through the `request` stream and passed to the callback function) but is not performed on the `response` stream (available from the `response` event) which is the unmodified `http.IncomingMessage` object which may contain compressed data. See example below.
-- `jar` - if `true`, remember cookies for future use (or define your custom cookie jar; see examples section)
-
----
-
-- `agent` - `http(s).Agent` instance to use
-- `agentClass` - alternatively specify your agent's class name
-- `agentOptions` - and pass its options. **Note:** for HTTPS see [tls API doc for TLS/SSL options](http://nodejs.org/api/tls.html#tls_tls_connect_options_callback) and the [documentation above](#using-optionsagentoptions).
-- `forever` - set to `true` to use the [forever-agent](https://github.com/request/forever-agent) **Note:** Defaults to `http(s).Agent({keepAlive:true})` in node 0.12+
-- `pool` - an object describing which agents to use for the request. If this option is omitted the request will use the global agent (as long as your options allow for it). Otherwise, request will search the pool for your custom agent. If no custom agent is found, a new agent will be created and added to the pool. **Note:** `pool` is used only when the `agent` option is not specified.
-  - A `maxSockets` property can also be provided on the `pool` object to set the max number of sockets for all agents created (ex: `pool: {maxSockets: Infinity}`).
-  - Note that if you are sending multiple requests in a loop and creating
-    multiple new `pool` objects, `maxSockets` will not work as intended. To
-    work around this, either use [`request.defaults`](#requestdefaultsoptions)
-    with your pool options or create the pool object with the `maxSockets`
-    property outside of the loop.
-- `timeout` - integer containing the number of milliseconds to wait for a
-server to send response headers (and start the response body) before aborting
-the request. Note that if the underlying TCP connection cannot be established,
-the OS-wide TCP connection timeout will overrule the `timeout` option ([the
-default in Linux can be anywhere from 20-120 seconds][linux-timeout]).
-
-[linux-timeout]: http://www.sekuda.com/overriding_the_default_linux_kernel_20_second_tcp_socket_connect_timeout
-
----
-
-- `localAddress` - local interface to bind for network connections.
-- `proxy` - an HTTP proxy to be used. Supports proxy Auth with Basic Auth, identical to support for the `url` parameter (by embedding the auth info in the `uri`)
-- `strictSSL` - if `true`, requires SSL certificates be valid. **Note:** to use your own certificate authority, you need to specify an agent that was created with that CA as an option.
-- `tunnel` - controls the behavior of
-  [HTTP `CONNECT` tunneling](https://en.wikipedia.org/wiki/HTTP_tunnel#HTTP_CONNECT_tunneling)
-  as follows:
-   - `undefined` (default) - `true` if the destination is `https`, `false` otherwise
-   - `true` - always tunnel to the destination by making a `CONNECT` request to
-     the proxy
-   - `false` - request the destination as a `GET` request.
-- `proxyHeaderWhiteList` - a whitelist of headers to send to a
-  tunneling proxy.
-- `proxyHeaderExclusiveList` - a whitelist of headers to send
-  exclusively to a tunneling proxy and not to destination.
-
----
-
-- `time` - if `true`, the request-response cycle (including all redirects) is timed at millisecond resolution. When set, the following properties are added to the response object:
-  - `elapsedTime` Duration of the entire request/response in milliseconds (*deprecated*).
-  - `responseStartTime` Timestamp when the response began (in Unix Epoch milliseconds) (*deprecated*).
-  - `timingStart` Timestamp of the start of the request (in Unix Epoch milliseconds).
-  - `timings` Contains event timestamps in millisecond resolution relative to `timingStart`. If there were redirects, the properties reflect the timings of the final request in the redirect chain:
-    - `socket` Relative timestamp when the [`http`](https://nodejs.org/api/http.html#http_event_socket) module's `socket` event fires. This happens when the socket is assigned to the request.
-    - `lookup` Relative timestamp when the [`net`](https://nodejs.org/api/net.html#net_event_lookup) module's `lookup` event fires. This happens when the DNS has been resolved.
-    - `connect`: Relative timestamp when the [`net`](https://nodejs.org/api/net.html#net_event_connect) module's `connect` event fires. This happens when the server acknowledges the TCP connection.
-    - `response`: Relative timestamp when the [`http`](https://nodejs.org/api/http.html#http_event_response) module's `response` event fires. This happens when the first bytes are received from the server.
-    - `end`: Relative timestamp when the last bytes of the response are received.
-  - `timingPhases` Contains the durations of each request phase. If there were redirects, the properties reflect the timings of the final request in the redirect chain:
-    - `wait`: Duration of socket initialization (`timings.socket`)
-    - `dns`: Duration of DNS lookup (`timings.lookup` - `timings.socket`)
-    - `tcp`: Duration of TCP connection (`timings.connect` - `timings.socket`)
-    - `firstByte`: Duration of HTTP server response (`timings.response` - `timings.connect`)
-    - `download`: Duration of HTTP download (`timings.end` - `timings.response`)
-    - `total`: Duration entire HTTP round-trip (`timings.end`)
-
-- `har` - a [HAR 1.2 Request Object](http://www.softwareishard.com/blog/har-12-spec/#request), will be processed from HAR format into options overwriting matching values *(see the [HAR 1.2 section](#support-for-har-1.2) for details)*
-- `callback` - alternatively pass the request's callback in the options object
-
-The callback argument gets 3 arguments:
-
-1. An `error` when applicable (usually from [`http.ClientRequest`](http://nodejs.org/api/http.html#http_class_http_clientrequest) object)
-2. An [`http.IncomingMessage`](https://nodejs.org/api/http.html#http_class_http_incomingmessage) object (Response object)
-3. The third is the `response` body (`String` or `Buffer`, or JSON object if the `json` option is supplied)

-## Convenience methods
-
-There are also shorthand methods for different HTTP METHODs and some other conveniences.
-
-
-### request.defaults(options)
-
-This method **returns a wrapper** around the normal request API that defaults
-to whatever options you pass to it.
-
-**Note:** `request.defaults()` **does not** modify the global request API;
-instead, it **returns a wrapper** that has your default settings applied to it.
-
-**Note:** You can call `.defaults()` on the wrapper that is returned from
-`request.defaults` to add/override defaults that were previously defaulted.
-
-For example:
-```js
-//requests using baseRequest() will set the 'x-token' header
-var baseRequest = request.defaults({
-  headers: {'x-token': 'my-token'}
-})
-
-//requests using specialRequest() will include the 'x-token' header set in
-//baseRequest and will also include the 'special' header
-var specialRequest = baseRequest.defaults({
-  headers: {special: 'special value'}
-})
-```
-
-### request.METHOD()
-
-These HTTP method convenience functions act just like `request()` but with a default method already set for you:
-
-- *request.get()*: Defaults to `method: "GET"`.
-- *request.post()*: Defaults to `method: "POST"`.
-- *request.put()*: Defaults to `method: "PUT"`.
-- *request.patch()*: Defaults to `method: "PATCH"`.
-- *request.del() / request.delete()*: Defaults to `method: "DELETE"`.
-- *request.head()*: Defaults to `method: "HEAD"`.
-- *request.options()*: Defaults to `method: "OPTIONS"`.
-
-### request.cookie()
-
-Function that creates a new cookie.
-
-```js
-request.cookie('key1=value1')
-```
-### request.jar()
-
-Function that creates a new cookie jar.
-
-```js
-request.jar()
-```
-
-[back to top](#table-of-contents)

-
-
-## Debugging
-
-There are at least three ways to debug the operation of `request`:
-
-1. Launch the node process like `NODE_DEBUG=request node script.js`
-   (`lib,request,otherlib` works too).
-
-2. Set `require('request').debug = true` at any time (this does the same thing
-   as #1).
-
-3. Use the [request-debug module](https://github.com/request/request-debug) to
-   view request and response headers and bodies.
-

-
-## Timeouts
-
-Most requests to external servers should have a timeout attached, in case the
-server is not responding in a timely manner. Without a timeout, your code may
-have a socket open/consume resources for minutes or more.
-
-There are two main types of timeouts: **connection timeouts** and **read
-timeouts**. A connect timeout occurs if the timeout is hit while your client is
-attempting to establish a connection to a remote machine (corresponding to the
-[connect() call][connect] on the socket). A read timeout occurs any time the
-server is too slow to send back a part of the response.
-
-These two situations have widely different implications for what went wrong
-with the request, so it's useful to be able to distinguish them. You can detect
-timeout errors by checking `err.code` for an 'ETIMEDOUT' value. Further, you
-can detect whether the timeout was a connection timeout by checking if the
-`err.connect` property is set to `true`.
-
-```js
-request.get('http://10.255.255.1', {timeout: 1500}, function(err) {
-    console.log(err.code === 'ETIMEDOUT');
-    // Set to `true` if the timeout was a connection timeout, `false` or
-    // `undefined` otherwise.
-    console.log(err.connect === true);
-    process.exit(0);
-});
-```
-
-[connect]: http://linux.die.net/man/2/connect
-
-## Examples:
-
-```js
-  var request = require('request')
-    , rand = Math.floor(Math.random()*100000000).toString()
-    ;
-  request(
-    { method: 'PUT'
-    , uri: 'http://mikeal.iriscouch.com/testjs/' + rand
-    , multipart:
-      [ { 'content-type': 'application/json'
-        ,  body: JSON.stringify({foo: 'bar', _attachments: {'message.txt': {follows: true, length: 18, 'content_type': 'text/plain' }}})
-        }
-      , { body: 'I am an attachment' }
-      ]
-    }
-  , function (error, response, body) {
-      if(response.statusCode == 201){
-        console.log('document saved as: http://mikeal.iriscouch.com/testjs/'+ rand)
-      } else {
-        console.log('error: '+ response.statusCode)
-        console.log(body)
-      }
-    }
-  )
-```
-
-For backwards-compatibility, response compression is not supported by default.
-To accept gzip-compressed responses, set the `gzip` option to `true`. Note
-that the body data passed through `request` is automatically decompressed
-while the response object is unmodified and will contain compressed data if
-the server sent a compressed response.
-
-```js
-  var request = require('request')
-  request(
-    { method: 'GET'
-    , uri: 'http://www.google.com'
-    , gzip: true
-    }
-  , function (error, response, body) {
-      // body is the decompressed response body
-      console.log('server encoded the data as: ' + (response.headers['content-encoding'] || 'identity'))
-      console.log('the decoded data is: ' + body)
-    }
-  )
-  .on('data', function(data) {
-    // decompressed data as it is received
-    console.log('decoded chunk: ' + data)
-  })
-  .on('response', function(response) {
-    // unmodified http.IncomingMessage object
-    response.on('data', function(data) {
-      // compressed data as it is received
-      console.log('received ' + data.length + ' bytes of compressed data')
-    })
-  })
-```
-
-Cookies are disabled by default (else, they would be used in subsequent requests). To enable cookies, set `jar` to `true` (either in `defaults` or `options`).
-
-```js
-var request = request.defaults({jar: true})
-request('http://www.google.com', function () {
-  request('http://images.google.com')
-})
-```
-
-To use a custom cookie jar (instead of `request`’s global cookie jar), set `jar` to an instance of `request.jar()` (either in `defaults` or `options`)
-
-```js
-var j = request.jar()
-var request = request.defaults({jar:j})
-request('http://www.google.com', function () {
-  request('http://images.google.com')
-})
-```
-
-OR
-
-```js
-var j = request.jar();
-var cookie = request.cookie('key1=value1');
-var url = 'http://www.google.com';
-j.setCookie(cookie, url);
-request({url: url, jar: j}, function () {
-  request('http://images.google.com')
-})
-```
-
-To use a custom cookie store (such as a
-[`FileCookieStore`](https://github.com/mitsuru/tough-cookie-filestore)
-which supports saving to and restoring from JSON files), pass it as a parameter
-to `request.jar()`:
-
-```js
-var FileCookieStore = require('tough-cookie-filestore');
-// NOTE - currently the 'cookies.json' file must already exist!
-var j = request.jar(new FileCookieStore('cookies.json'));
-request = request.defaults({ jar : j })
-request('http://www.google.com', function() {
-  request('http://images.google.com')
-})
-```
-
-The cookie store must be a
-[`tough-cookie`](https://github.com/SalesforceEng/tough-cookie)
-store and it must support synchronous operations; see the
-[`CookieStore` API docs](https://github.com/SalesforceEng/tough-cookie#cookiestore-api)
-for details.
-
-To inspect your cookie jar after a request:
-
-```js
-var j = request.jar()
-request({url: 'http://www.google.com', jar: j}, function () {
-  var cookie_string = j.getCookieString(url); // "key1=value1; key2=value2; ..."
-  var cookies = j.getCookies(url);
-  // [{key: 'key1', value: 'value1', domain: "www.google.com", ...}, ...]
-})
-```

-#### Safer Node.js Buffer API
-
-**Use the new Node.js Buffer APIs (`Buffer.from`, `Buffer.alloc`,
-`Buffer.allocUnsafe`, `Buffer.allocUnsafeSlow`) in all versions of Node.js.**
-
-**Uses the built-in implementation when available.**
-
-## install
-
-```
-npm install safe-buffer
-```
-
-[Get supported safe-buffer with the Tidelift Subscription](https://tidelift.com/subscription/pkg/npm-safe-buffer?utm_source=npm-safe-buffer&utm_medium=referral&utm_campaign=readme)
-
-## usage
-
-The goal of this package is to provide a safe replacement for the node.js `Buffer`.
-
-It's a drop-in replacement for `Buffer`. You can use it by adding one `require` line to
-the top of your node.js modules:
-
-```js
-var Buffer = require('safe-buffer').Buffer
-
-// Existing buffer code will continue to work without issues:
-
-new Buffer('hey', 'utf8')
-new Buffer([1, 2, 3], 'utf8')
-new Buffer(obj)
-new Buffer(16) // create an uninitialized buffer (potentially unsafe)
-
-// But you can use these new explicit APIs to make clear what you want:
-
-Buffer.from('hey', 'utf8') // convert from many types to a Buffer
-Buffer.alloc(16) // create a zero-filled buffer (safe)
-Buffer.allocUnsafe(16) // create an uninitialized buffer (potentially unsafe)
-```
-
-## api
-
-### Class Method: Buffer.from(array)
-<!-- YAML
-added: v3.0.0
--->
-
-* `array` {Array}
-
-Allocates a new `Buffer` using an `array` of octets.
-
-```js
-const buf = Buffer.from([0x62,0x75,0x66,0x66,0x65,0x72]);
-  // creates a new Buffer containing ASCII bytes
-  // ['b','u','f','f','e','r']
-```
-
-A `TypeError` will be thrown if `array` is not an `Array`.
-
-### Class Method: Buffer.from(arrayBuffer[, byteOffset[, length]])
-<!-- YAML
-added: v5.10.0
--->
-
-* `arrayBuffer` {ArrayBuffer} The `.buffer` property of a `TypedArray` or
-  a `new ArrayBuffer()`
-* `byteOffset` {Number} Default: `0`
-* `length` {Number} Default: `arrayBuffer.length - byteOffset`
-
-When passed a reference to the `.buffer` property of a `TypedArray` instance,
-the newly created `Buffer` will share the same allocated memory as the
-TypedArray.
-
-```js
-const arr = new Uint16Array(2);
-arr[0] = 5000;
-arr[1] = 4000;
-
-const buf = Buffer.from(arr.buffer); // shares the memory with arr;
-
-console.log(buf);
-  // Prints: <Buffer 88 13 a0 0f>
-
-// changing the TypedArray changes the Buffer also
-arr[1] = 6000;
-
-console.log(buf);
-  // Prints: <Buffer 88 13 70 17>
-```
-
-The optional `byteOffset` and `length` arguments specify a memory range within
-the `arrayBuffer` that will be shared by the `Buffer`.
-
-```js
-const ab = new ArrayBuffer(10);
-const buf = Buffer.from(ab, 0, 2);
-console.log(buf.length);
-  // Prints: 2
-```
-
-A `TypeError` will be thrown if `arrayBuffer` is not an `ArrayBuffer`.
-
-### Class Method: Buffer.from(buffer)
-<!-- YAML
-added: v3.0.0
--->
-
-* `buffer` {Buffer}
-
-Copies the passed `buffer` data onto a new `Buffer` instance.
-
-```js
-const buf1 = Buffer.from('buffer');
-const buf2 = Buffer.from(buf1);
-
-buf1[0] = 0x61;
-console.log(buf1.toString());
-  // 'auffer'
-console.log(buf2.toString());
-  // 'buffer' (copy is not changed)
-```
-
-A `TypeError` will be thrown if `buffer` is not a `Buffer`.
-
-### Class Method: Buffer.from(str[, encoding])
-<!-- YAML
-added: v5.10.0
--->
-
-* `str` {String} String to encode.
-* `encoding` {String} Encoding to use, Default: `'utf8'`
-
-Creates a new `Buffer` containing the given JavaScript string `str`. If
-provided, the `encoding` parameter identifies the character encoding.
-If not provided, `encoding` defaults to `'utf8'`.
-
-```js
-const buf1 = Buffer.from('this is a tést');
-console.log(buf1.toString());
-  // prints: this is a tést
-console.log(buf1.toString('ascii'));
-  // prints: this is a tC)st

-### Class Method: Buffer.alloc(size[, fill[, encoding]])
-<!-- YAML
-added: v5.10.0
--->
-
-* `size` {Number}
-* `fill` {Value} Default: `undefined`
-* `encoding` {String} Default: `utf8`
-
-Allocates a new `Buffer` of `size` bytes. If `fill` is `undefined`, the
-`Buffer` will be *zero-filled*.
-
-```js
-const buf = Buffer.alloc(5);
-console.log(buf);
-  // <Buffer 00 00 00 00 00>
-```
-
-The `size` must be less than or equal to the value of
-`require('buffer').kMaxLength` (on 64-bit architectures, `kMaxLength` is
-`(2^31)-1`). Otherwise, a [`RangeError`][] is thrown. A zero-length Buffer will
-be created if a `size` less than or equal to 0 is specified.
-
-If `fill` is specified, the allocated `Buffer` will be initialized by calling
-`buf.fill(fill)`. See [`buf.fill()`][] for more information.
-
-```js
-const buf = Buffer.alloc(5, 'a');
-console.log(buf);
-  // <Buffer 61 61 61 61 61>
-```
-
-If both `fill` and `encoding` are specified, the allocated `Buffer` will be
-initialized by calling `buf.fill(fill, encoding)`. For example:
-
-```js
-const buf = Buffer.alloc(11, 'aGVsbG8gd29ybGQ=', 'base64');
-console.log(buf);
-  // <Buffer 68 65 6c 6c 6f 20 77 6f 72 6c 64>
-```
-
-Calling `Buffer.alloc(size)` can be significantly slower than the alternative
-`Buffer.allocUnsafe(size)` but ensures that the newly created `Buffer` instance
-contents will *never contain sensitive data*.
-
-A `TypeError` will be thrown if `size` is not a number.
-
-### Class Method: Buffer.allocUnsafe(size)
-<!-- YAML
-added: v5.10.0
--->
-
-* `size` {Number}
-
-Allocates a new *non-zero-filled* `Buffer` of `size` bytes.  The `size` must
-be less than or equal to the value of `require('buffer').kMaxLength` (on 64-bit
-architectures, `kMaxLength` is `(2^31)-1`). Otherwise, a [`RangeError`][] is
-thrown. A zero-length Buffer will be created if a `size` less than or equal to
-0 is specified.
-
-The underlying memory for `Buffer` instances created in this way is *not
-initialized*. The contents of the newly created `Buffer` are unknown and
-*may contain sensitive data*. Use [`buf.fill(0)`][] to initialize such
-`Buffer` instances to zeroes.
-
-```js
-const buf = Buffer.allocUnsafe(5);
-console.log(buf);
-  // <Buffer 78 e0 82 02 01>
-  // (octets will be different, every time)
-buf.fill(0);
-console.log(buf);
-  // <Buffer 00 00 00 00 00>
-```
-
-A `TypeError` will be thrown if `size` is not a number.
-
-Note that the `Buffer` module pre-allocates an internal `Buffer` instance of
-size `Buffer.poolSize` that is used as a pool for the fast allocation of new
-`Buffer` instances created using `Buffer.allocUnsafe(size)` (and the deprecated
-`new Buffer(size)` constructor) only when `size` is less than or equal to
-`Buffer.poolSize >> 1` (floor of `Buffer.poolSize` divided by two). The default
-value of `Buffer.poolSize` is `8192` but can be modified.
-
-Use of this pre-allocated internal memory pool is a key difference between
-calling `Buffer.alloc(size, fill)` vs. `Buffer.allocUnsafe(size).fill(fill)`.
-Specifically, `Buffer.alloc(size, fill)` will *never* use the internal Buffer
-pool, while `Buffer.allocUnsafe(size).fill(fill)` *will* use the internal
-Buffer pool if `size` is less than or equal to half `Buffer.poolSize`. The
-difference is subtle but can be important when an application requires the
-additional performance that `Buffer.allocUnsafe(size)` provides.
-
-### Class Method: Buffer.allocUnsafeSlow(size)
-<!-- YAML
-added: v5.10.0
--->
-
-* `size` {Number}
-
-Allocates a new *non-zero-filled* and non-pooled `Buffer` of `size` bytes.  The
-`size` must be less than or equal to the value of
-`require('buffer').kMaxLength` (on 64-bit architectures, `kMaxLength` is
-`(2^31)-1`). Otherwise, a [`RangeError`][] is thrown. A zero-length Buffer will
-be created if a `size` less than or equal to 0 is specified.
-
-The underlying memory for `Buffer` instances created in this way is *not
-initialized*. The contents of the newly created `Buffer` are unknown and
-*may contain sensitive data*. Use [`buf.fill(0)`][] to initialize such
-`Buffer` instances to zeroes.
-
-When using `Buffer.allocUnsafe()` to allocate new `Buffer` instances,
-allocations under 4KB are, by default, sliced from a single pre-allocated
-`Buffer`. This allows applications to avoid the garbage collection overhead of
-creating many individually allocated Buffers. This approach improves both
-performance and memory usage by eliminating the need to track and cleanup as
-many `Persistent` objects.
-
-However, in the case where a developer may need to retain a small chunk of
-memory from a pool for an indeterminate amount of time, it may be appropriate
-to create an un-pooled Buffer instance using `Buffer.allocUnsafeSlow()` then
-copy out the relevant bits.
-
-```js
-// need to keep around a few small chunks of memory
-const store = [];
-
-socket.on('readable', () => {
-  const data = socket.read();
-  // allocate for retained data
-  const sb = Buffer.allocUnsafeSlow(10);
-  // copy the data into the new allocation
-  data.copy(sb, 0, 0, 10);
-  store.push(sb);
-});
-```
-
-Use of `Buffer.allocUnsafeSlow()` should be used only as a last resort *after*
-a developer has observed undue memory retention in their applications.
-
-A `TypeError` will be thrown if `size` is not a number.
-
-### All the Rest
-
-The rest of the `Buffer` API is exactly the same as in node.js.
-[See the docs](https://nodejs.org/api/buffer.html).

-- [Node.js Enhancement Proposal: Buffer.from/Buffer.alloc/Buffer.zalloc/Buffer() soft-deprecate](https://github.com/nodejs/node-eps/pull/4)
-
-## Why is `Buffer` unsafe?
-
-Today, the node.js `Buffer` constructor is overloaded to handle many different argument
-types like `String`, `Array`, `Object`, `TypedArrayView` (`Uint8Array`, etc.),
-`ArrayBuffer`, and also `Number`.
-
-The API is optimized for convenience: you can throw any type at it, and it will try to do
-what you want.
-
-Because the Buffer constructor is so powerful, you often see code like this:
-
-```js
-// Convert UTF-8 strings to hex
-function toHex (str) {
-  return new Buffer(str).toString('hex')
-}
-```
-
-***But what happens if `toHex` is called with a `Number` argument?***
-
-### Remote Memory Disclosure
-
-If an attacker can make your program call the `Buffer` constructor with a `Number`
-argument, then they can make it allocate uninitialized memory from the node.js process.
-This could potentially disclose TLS private keys, user data, or database passwords.
-
-When the `Buffer` constructor is passed a `Number` argument, it returns an
-**UNINITIALIZED** block of memory of the specified `size`. When you create a `Buffer` like
-this, you **MUST** overwrite the contents before returning it to the user.
-
-From the [node.js docs](https://nodejs.org/api/buffer.html#buffer_new_buffer_size):
-
-> `new Buffer(size)`
->
-> - `size` Number
->
-> The underlying memory for `Buffer` instances created in this way is not initialized.
-> **The contents of a newly created `Buffer` are unknown and could contain sensitive
-> data.** Use `buf.fill(0)` to initialize a Buffer to zeroes.
-
-(Emphasis our own.)
-
-Whenever the programmer intended to create an uninitialized `Buffer` you often see code
-like this:
-
-```js
-var buf = new Buffer(16)
-
-// Immediately overwrite the uninitialized buffer with data from another buffer
-for (var i = 0; i < buf.length; i++) {
-  buf[i] = otherBuf[i]
-}
-```
-
-
-### Would this ever be a problem in real code?
-
-Yes. It's surprisingly common to forget to check the type of your variables in a
-dynamically-typed language like JavaScript.
-
-Usually the consequences of assuming the wrong type is that your program crashes with an
-uncaught exception. But the failure mode for forgetting to check the type of arguments to
-the `Buffer` constructor is more catastrophic.
-
-Here's an example of a vulnerable service that takes a JSON payload and converts it to
-hex:
-
-```js
-// Take a JSON payload {str: "some string"} and convert it to hex
-var server = http.createServer(function (req, res) {
-  var data = ''
-  req.setEncoding('utf8')
-  req.on('data', function (chunk) {
-    data += chunk
-  })
-  req.on('end', function () {
-    var body = JSON.parse(data)
-    res.end(new Buffer(body.str).toString('hex'))
-  })
-})
-
-server.listen(8080)
-```
-
-In this example, an http client just has to send:
-
-```json
-{
-  "str": 1000
-}
-```
-
-and it will get back 1,000 bytes of uninitialized memory from the server.
-
-This is a very serious bug. It's similar in severity to the
-[the Heartbleed bug](http://heartbleed.com/) that allowed disclosure of OpenSSL process
-memory by remote attackers.
-
-
-### Which real-world packages were vulnerable?
-
-#### [`bittorrent-dht`](https://www.npmjs.com/package/bittorrent-dht)
-
-[Mathias Buus](https://github.com/mafintosh) and I
-([Feross Aboukhadijeh](http://feross.org/)) found this issue in one of our own packages,
-[`bittorrent-dht`](https://www.npmjs.com/package/bittorrent-dht). The bug would allow
-anyone on the internet to send a series of messages to a user of `bittorrent-dht` and get
-them to reveal 20 bytes at a time of uninitialized memory from the node.js process.
-
-Here's
-[the commit](https://github.com/feross/bittorrent-dht/commit/6c7da04025d5633699800a99ec3fbadf70ad35b8)
-that fixed it. We released a new fixed version, created a
-[Node Security Project disclosure](https://nodesecurity.io/advisories/68), and deprecated all
-vulnerable versions on npm so users will get a warning to upgrade to a newer version.
-
-#### [`ws`](https://www.npmjs.com/package/ws)
-
-That got us wondering if there were other vulnerable packages. Sure enough, within a short
-period of time, we found the same issue in [`ws`](https://www.npmjs.com/package/ws), the
-most popular WebSocket implementation in node.js.
-
-If certain APIs were called with `Number` parameters instead of `String` or `Buffer` as
-expected, then uninitialized server memory would be disclosed to the remote peer.
-
-These were the vulnerable methods:
-
-```js
-socket.send(number)
-socket.ping(number)
-socket.pong(number)
-```
-
-Here's a vulnerable socket server with some echo functionality:
-
-```js
-server.on('connection', function (socket) {
-  socket.on('message', function (message) {
-    message = JSON.parse(message)
-    if (message.type === 'echo') {
-      socket.send(message.data) // send back the user's message
-    }
-  })
-})
-```
-
-`socket.send(number)` called on the server, will disclose server memory.
-
-Here's [the release](https://github.com/websockets/ws/releases/tag/1.0.1) where the issue
-was fixed, with a more detailed explanation. Props to
-[Arnout Kazemier](https://github.com/3rd-Eden) for the quick fix. Here's the
-[Node Security Project disclosure](https://nodesecurity.io/advisories/67).
-
-
-### What's the solution?
-
-It's important that node.js offers a fast way to get memory otherwise performance-critical
-applications would needlessly get a lot slower.
-
-But we need a better way to *signal our intent* as programmers. **When we want
-uninitialized memory, we should request it explicitly.**
-
-Sensitive functionality should not be packed into a developer-friendly API that loosely
-accepts many different types. This type of API encourages the lazy practice of passing
-variables in without checking the type very carefully.
-
-#### A new API: `Buffer.allocUnsafe(number)`
-
-The functionality of creating buffers with uninitialized memory should be part of another
-API. We propose `Buffer.allocUnsafe(number)`. This way, it's not part of an API that
-frequently gets user input of all sorts of different types passed into it.
-
-```js
-var buf = Buffer.allocUnsafe(16) // careful, uninitialized memory!
-
-// Immediately overwrite the uninitialized buffer with data from another buffer
-for (var i = 0; i < buf.length; i++) {
-  buf[i] = otherBuf[i]
-}
-```
-
-
-### How do we fix node.js core?
-
-We sent [a PR to node.js core](https://github.com/nodejs/node/pull/4514) (merged as
-`semver-major`) which defends against one case:
-
-```js
-var str = 16
-new Buffer(str, 'utf8')
-```
-
-In this situation, it's implied that the programmer intended the first argument to be a
-string, since they passed an encoding as a second argument. Today, node.js will allocate
-uninitialized memory in the case of `new Buffer(number, encoding)`, which is probably not
-what the programmer intended.
-
-But this is only a partial solution, since if the programmer does `new Buffer(variable)`
-(without an `encoding` parameter) there's no way to know what they intended. If `variable`
-is sometimes a number, then uninitialized memory will sometimes be returned.
-
-### What's the real long-term fix?
-
-We could deprecate and remove `new Buffer(number)` and use `Buffer.allocUnsafe(number)` when
-we need uninitialized memory. But that would break 1000s of packages.
-
-~~We believe the best solution is to:~~
-
-~~1. Change `new Buffer(number)` to return safe, zeroed-out memory~~
-
-~~2. Create a new API for creating uninitialized Buffers. We propose: `Buffer.allocUnsafe(number)`~~
-
-#### Update
-
-We now support adding three new APIs:
-
-- `Buffer.from(value)` - convert from any type to a buffer
-- `Buffer.alloc(size)` - create a zero-filled buffer
-- `Buffer.allocUnsafe(size)` - create an uninitialized buffer with given size
-
-This solves the core problem that affected `ws` and `bittorrent-dht` which is
-`Buffer(variable)` getting tricked into taking a number argument.
-
-This way, existing code continues working and the impact on the npm ecosystem will be
-minimal. Over time, npm maintainers can migrate performance-critical code to use
-`Buffer.allocUnsafe(number)` instead of `new Buffer(number)`.
-
-
-### Conclusion
-
-We think there's a serious design issue with the `Buffer` API as it exists today. It
-promotes insecure software by putting high-risk functionality into a convenient API
-with friendly "developer ergonomics".
-
-This wasn't merely a theoretical exercise because we found the issue in some of the
-most popular npm packages.
-
-Fortunately, there's an easy fix that can be applied today. Use `safe-buffer` in place of
-`buffer`.
-
-```js
-var Buffer = require('safe-buffer').Buffer
-```
-
-Eventually, we hope that node.js core can switch to this new, safer behavior. We believe
-the impact on the ecosystem would be minimal since it's not a breaking change.
-Well-maintained, popular packages would be updated to use `Buffer.alloc` quickly, while
-older, insecure packages would magically become safe from this attack vector.

-The [UNIX command](http://en.wikipedia.org/wiki/Rm_(Unix)) `rm -rf` for node.
-
-Install with `npm install rimraf`, or just drop rimraf.js somewhere.
-
-## API
-
-`rimraf(f, [opts], callback)`
-
-The first parameter will be interpreted as a globbing pattern for files. If you
-want to disable globbing you can do so with `opts.disableGlob` (defaults to
-`false`). This might be handy, for instance, if you have filenames that contain
-globbing wildcard characters.
-
-The callback will be called with an error if there is one.  Certain
-errors are handled for you:
-
-* Windows: `EBUSY` and `ENOTEMPTY` - rimraf will back off a maximum of
-  `opts.maxBusyTries` times before giving up, adding 100ms of wait
-  between each attempt.  The default `maxBusyTries` is 3.
-* `ENOENT` - If the file doesn't exist, rimraf will return
-  successfully, since your desired outcome is already the case.
-* `EMFILE` - Since `readdir` requires opening a file descriptor, it's
-  possible to hit `EMFILE` if too many file descriptors are in use.
-  In the sync case, there's nothing to be done for this.  But in the
-  async case, rimraf will gradually back off with timeouts up to
-  `opts.emfileWait` ms, which defaults to 1000.
-
-## options
-
-* unlink, chmod, stat, lstat, rmdir, readdir,
-  unlinkSync, chmodSync, statSync, lstatSync, rmdirSync, readdirSync
-
-    In order to use a custom file system library, you can override
-    specific fs functions on the options object.
-
-    If any of these functions are present on the options object, then
-    the supplied function will be used instead of the default fs
-    method.
-
-    Sync methods are only relevant for `rimraf.sync()`, of course.
-
-    For example:
-
-    ```javascript
-    var myCustomFS = require('some-custom-fs')
-
-    rimraf('some-thing', myCustomFS, callback)
-    ```
-
-* maxBusyTries
-
-    If an `EBUSY`, `ENOTEMPTY`, or `EPERM` error code is encountered
-    on Windows systems, then rimraf will retry with a linear backoff
-    wait of 100ms longer on each try.  The default maxBusyTries is 3.
-
-    Only relevant for async usage.
-
-* emfileWait
-
-    If an `EMFILE` error is encountered, then rimraf will retry
-    repeatedly with a linear backoff of 1ms longer on each try, until
-    the timeout counter hits this max.  The default limit is 1000.
-
-    If you repeatedly encounter `EMFILE` errors, then consider using
-    [graceful-fs](http://npm.im/graceful-fs) in your program.
-
-    Only relevant for async usage.
-
-* glob
-
-    Set to `false` to disable [glob](http://npm.im/glob) pattern
-    matching.
-
-    Set to an object to pass options to the glob module.  The default
-    glob options are `{ nosort: true, silent: true }`.
-
-    Glob version 6 is used in this module.
-
-    Relevant for both sync and async usage.
-
-* disableGlob
-
-    Set to any non-falsey value to disable globbing entirely.
-    (Equivalent to setting `glob: false`.)
-
-## rimraf.sync
-
-It can remove stuff synchronously, too.  But that's not so good.  Use
-the async API.  It's better.
-
-## CLI
-
-If installed with `npm install rimraf -g` it can be used as a global
-command `rimraf <path> [<path> ...]` which is useful for cross platform support.
-
-## mkdirp
-
-If you need to create a directory recursively, check out
-[mkdirp](https://github.com/substack/node-mkdirp).

-# Glob
-
-Match files using the patterns the shell uses, like stars and stuff.
-
-[![Build Status](https://travis-ci.org/isaacs/node-glob.svg?branch=master)](https://travis-ci.org/isaacs/node-glob/) [![Build Status](https://ci.appveyor.com/api/projects/status/kd7f3yftf7unxlsx?svg=true)](https://ci.appveyor.com/project/isaacs/node-glob) [![Coverage Status](https://coveralls.io/repos/isaacs/node-glob/badge.svg?branch=master&service=github)](https://coveralls.io/github/isaacs/node-glob?branch=master)
-
-This is a glob implementation in JavaScript.  It uses the `minimatch`
-library to do its matching.
-
-![](logo/glob.png)
-
-## Usage
-
-Install with npm
-
-```
-npm i glob
-```
-
-```javascript
-var glob = require("glob")
-
-// options is optional
-glob("**/*.js", options, function (er, files) {
-  // files is an array of filenames.
-  // If the `nonull` option is set, and nothing
-  // was found, then files is ["**/*.js"]
-  // er is an error object or null.
-})
-```
-
-## Glob Primer
-
-"Globs" are the patterns you type when you do stuff like `ls *.js` on
-the command line, or put `build/*` in a `.gitignore` file.
-
-Before parsing the path part patterns, braced sections are expanded
-into a set.  Braced sections start with `{` and end with `}`, with any
-number of comma-delimited sections within.  Braced sections may contain
-slash characters, so `a{/b/c,bcd}` would expand into `a/b/c` and `abcd`.
-
-The following characters have special magic meaning when used in a
-path portion:
-
-* `*` Matches 0 or more characters in a single path portion
-* `?` Matches 1 character
-* `[...]` Matches a range of characters, similar to a RegExp range.
-  If the first character of the range is `!` or `^` then it matches
-  any character not in the range.
-* `!(pattern|pattern|pattern)` Matches anything that does not match
-  any of the patterns provided.
-* `?(pattern|pattern|pattern)` Matches zero or one occurrence of the
-  patterns provided.
-* `+(pattern|pattern|pattern)` Matches one or more occurrences of the
-  patterns provided.
-* `*(a|b|c)` Matches zero or more occurrences of the patterns provided
-* `@(pattern|pat*|pat?erN)` Matches exactly one of the patterns
-  provided
-* `**` If a "globstar" is alone in a path portion, then it matches
-  zero or more directories and subdirectories searching for matches.
-  It does not crawl symlinked directories.
-
-### Dots
-
-If a file or directory path portion has a `.` as the first character,
-then it will not match any glob pattern unless that pattern's
-corresponding path part also has a `.` as its first character.
-
-For example, the pattern `a/.*/c` would match the file at `a/.b/c`.
-However the pattern `a/*/c` would not, because `*` does not start with
-a dot character.
-
-You can make glob treat dots as normal characters by setting
-`dot:true` in the options.
-
-### Basename Matching
-
-If you set `matchBase:true` in the options, and the pattern has no
-slashes in it, then it will seek for any file anywhere in the tree
-with a matching basename.  For example, `*.js` would match
-`test/simple/basic.js`.
-
-### Empty Sets
-
-If no matching files are found, then an empty array is returned.  This
-differs from the shell, where the pattern itself is returned.  For
-example:
-
-    $ echo a*s*d*f
-    a*s*d*f
-
-To get the bash-style behavior, set the `nonull:true` in the options.
-
-### See Also:
-
-* `man sh`
-* `man bash` (Search for "Pattern Matching")
-* `man 3 fnmatch`
-* `man 5 gitignore`
-* [minimatch documentation](https://github.com/isaacs/minimatch)
-
-## glob.hasMagic(pattern, [options])
-
-Returns `true` if there are any special characters in the pattern, and
-`false` otherwise.
-
-Note that the options affect the results.  If `noext:true` is set in
-the options object, then `+(a|b)` will not be considered a magic
-pattern.  If the pattern has a brace expansion, like `a/{b/c,x/y}`
-then that is considered magical, unless `nobrace:true` is set in the
-options.
-
-## glob(pattern, [options], cb)
-
-* `pattern` `{String}` Pattern to be matched
-* `options` `{Object}`
-* `cb` `{Function}`
-  * `err` `{Error | null}`
-  * `matches` `{Array<String>}` filenames found matching the pattern
-
-Perform an asynchronous glob search.
-
-## glob.sync(pattern, [options])
-
-* `pattern` `{String}` Pattern to be matched
-* `options` `{Object}`
-* return: `{Array<String>}` filenames found matching the pattern
-
-Perform a synchronous glob search.
-
-## Class: glob.Glob
-
-Create a Glob object by instantiating the `glob.Glob` class.
-
-```javascript
-var Glob = require("glob").Glob
-var mg = new Glob(pattern, options, cb)
-```
-
-It's an EventEmitter, and starts walking the filesystem to find matches
-immediately.
-
-### new glob.Glob(pattern, [options], [cb])
-
-* `pattern` `{String}` pattern to search for
-* `options` `{Object}`
-* `cb` `{Function}` Called when an error occurs, or matches are found
-  * `err` `{Error | null}`
-  * `matches` `{Array<String>}` filenames found matching the pattern
-
-Note that if the `sync` flag is set in the options, then matches will
-be immediately available on the `g.found` member.
-
-### Properties
-
-* `minimatch` The minimatch object that the glob uses.
-* `options` The options object passed in.
-* `aborted` Boolean which is set to true when calling `abort()`.  There
-  is no way at this time to continue a glob search after aborting, but
-  you can re-use the statCache to avoid having to duplicate syscalls.
-* `cache` Convenience object.  Each field has the following possible
-  values:
-  * `false` - Path does not exist
-  * `true` - Path exists
-  * `'FILE'` - Path exists, and is not a directory
-  * `'DIR'` - Path exists, and is a directory
-  * `[file, entries, ...]` - Path exists, is a directory, and the
-    array value is the results of `fs.readdir`
-* `statCache` Cache of `fs.stat` results, to prevent statting the same
-  path multiple times.
-* `symlinks` A record of which paths are symbolic links, which is
-  relevant in resolving `**` patterns.
-* `realpathCache` An optional object which is passed to `fs.realpath`
-  to minimize unnecessary syscalls.  It is stored on the instantiated
-  Glob object, and may be re-used.
-
-### Events
-
-* `end` When the matching is finished, this is emitted with all the
-  matches found.  If the `nonull` option is set, and no match was found,
-  then the `matches` list contains the original pattern.  The matches
-  are sorted, unless the `nosort` flag is set.
-* `match` Every time a match is found, this is emitted with the specific
-  thing that matched. It is not deduplicated or resolved to a realpath.
-* `error` Emitted when an unexpected error is encountered, or whenever
-  any fs error occurs if `options.strict` is set.
-* `abort` When `abort()` is called, this event is raised.
-
-### Methods
-
-* `pause` Temporarily stop the search
-* `resume` Resume the search
-* `abort` Stop the search forever
-
-### Options
-
-All the options that can be passed to Minimatch can also be passed to
-Glob to change pattern matching behavior.  Also, some have been added,
-or have glob-specific ramifications.
-
-All options are false by default, unless otherwise noted.
-
-All options are added to the Glob object, as well.
-
-If you are running many `glob` operations, you can pass a Glob object
-as the `options` argument to a subsequent operation to shortcut some
-`stat` and `readdir` calls.  At the very least, you may pass in shared
-`symlinks`, `statCache`, `realpathCache`, and `cache` options, so that
-parallel glob operations will be sped up by sharing information about
-the filesystem.
-
-* `cwd` The current working directory in which to search.  Defaults
-  to `process.cwd()`.
-* `root` The place where patterns starting with `/` will be mounted
-  onto.  Defaults to `path.resolve(options.cwd, "/")` (`/` on Unix
-  systems, and `C:\` or some such on Windows.)
-* `dot` Include `.dot` files in normal matches and `globstar` matches.
-  Note that an explicit dot in a portion of the pattern will always
-  match dot files.
-* `nomount` By default, a pattern starting with a forward-slash will be
-  "mounted" onto the root setting, so that a valid filesystem path is
-  returned.  Set this flag to disable that behavior.
-* `mark` Add a `/` character to directory matches.  Note that this
-  requires additional stat calls.
-* `nosort` Don't sort the results.
-* `stat` Set to true to stat *all* results.  This reduces performance
-  somewhat, and is completely unnecessary, unless `readdir` is presumed
-  to be an untrustworthy indicator of file existence.
-* `silent` When an unusual error is encountered when attempting to
-  read a directory, a warning will be printed to stderr.  Set the
-  `silent` option to true to suppress these warnings.
-* `strict` When an unusual error is encountered when attempting to
-  read a directory, the process will just continue on in search of
-  other matches.  Set the `strict` option to raise an error in these
-  cases.
-* `cache` See `cache` property above.  Pass in a previously generated
-  cache object to save some fs calls.
-* `statCache` A cache of results of filesystem information, to prevent
-  unnecessary stat calls.  While it should not normally be necessary
-  to set this, you may pass the statCache from one glob() call to the
-  options object of another, if you know that the filesystem will not
-  change between calls.  (See "Race Conditions" below.)
-* `symlinks` A cache of known symbolic links.  You may pass in a
-  previously generated `symlinks` object to save `lstat` calls when
-  resolving `**` matches.
-* `sync` DEPRECATED: use `glob.sync(pattern, opts)` instead.
-* `nounique` In some cases, brace-expanded patterns can result in the
-  same file showing up multiple times in the result set.  By default,
-  this implementation prevents duplicates in the result set.  Set this
-  flag to disable that behavior.
-* `nonull` Set to never return an empty set, instead returning a set
-  containing the pattern itself.  This is the default in glob(3).
-* `debug` Set to enable debug logging in minimatch and glob.
-* `nobrace` Do not expand `{a,b}` and `{1..3}` brace sets.
-* `noglobstar` Do not match `**` against multiple filenames.  (Ie,
-  treat it as a normal `*` instead.)
-* `noext` Do not match `+(a|b)` "extglob" patterns.
-* `nocase` Perform a case-insensitive match.  Note: on
-  case-insensitive filesystems, non-magic patterns will match by
-  default, since `stat` and `readdir` will not raise errors.
-* `matchBase` Perform a basename-only match if the pattern does not
-  contain any slash characters.  That is, `*.js` would be treated as
-  equivalent to `**/*.js`, matching all js files in all directories.
-* `nodir` Do not match directories, only files.  (Note: to match
-  *only* directories, simply put a `/` at the end of the pattern.)
-* `ignore` Add a pattern or an array of glob patterns to exclude matches.
-  Note: `ignore` patterns are *always* in `dot:true` mode, regardless
-  of any other settings.
-* `follow` Follow symlinked directories when expanding `**` patterns.
-  Note that this can result in a lot of duplicate references in the
-  presence of cyclic links.
-* `realpath` Set to true to call `fs.realpath` on all of the results.
-  In the case of a symlink that cannot be resolved, the full absolute
-  path to the matched entry is returned (though it will usually be a
-  broken symlink)
-* `absolute` Set to true to always receive absolute paths for matched
-  files.  Unlike `realpath`, this also affects the values returned in
-  the `match` event.
-
-## Comparisons to other fnmatch/glob implementations
-
-While strict compliance with the existing standards is a worthwhile
-goal, some discrepancies exist between node-glob and other
-implementations, and are intentional.
-
-The double-star character `**` is supported by default, unless the
-`noglobstar` flag is set.  This is supported in the manner of bsdglob
-and bash 4.3, where `**` only has special significance if it is the only
-thing in a path part.  That is, `a/**/b` will match `a/x/y/b`, but
-`a/**b` will not.
-
-Note that symlinked directories are not crawled as part of a `**`,
-though their contents may match against subsequent portions of the
-pattern.  This prevents infinite loops and duplicates and the like.
-
-If an escaped pattern has no matches, and the `nonull` flag is set,
-then glob returns the pattern as-provided, rather than
-interpreting the character escapes.  For example,
-`glob.match([], "\\*a\\?")` will return `"\\*a\\?"` rather than
-`"*a?"`.  This is akin to setting the `nullglob` option in bash, except
-that it does not resolve escaped pattern characters.
-
-If brace expansion is not disabled, then it is performed before any
-other interpretation of the glob pattern.  Thus, a pattern like
-`+(a|{b),c)}`, which would not be valid in bash or zsh, is expanded
-**first** into the set of `+(a|b)` and `+(a|c)`, and those patterns are
-checked for validity.  Since those two are valid, matching proceeds.
-
-### Comments and Negation
-
-Previously, this module let you mark a pattern as a "comment" if it
-started with a `#` character, or a "negated" pattern if it started
-with a `!` character.
-
-These options were deprecated in version 5, and removed in version 6.
-
-To specify things that should not match, use the `ignore` option.
-
-## Windows
-
-**Please only use forward-slashes in glob expressions.**
-
-Though windows uses either `/` or `\` as its path separator, only `/`
-characters are used by this glob implementation.  You must use
-forward-slashes **only** in glob expressions.  Back-slashes will always
-be interpreted as escape characters, not path separators.
-
-Results from absolute patterns such as `/foo/*` are mounted onto the
-root setting using `path.join`.  On windows, this will by default result
-in `/foo/*` matching `C:\foo\bar.txt`.
-
-## Race Conditions
-
-Glob searching, by its very nature, is susceptible to race conditions,
-since it relies on directory walking and such.
-
-As a result, it is possible that a file that exists when glob looks for
-it may have been deleted or modified by the time it returns the result.
-
-As part of its internal implementation, this program caches all stat
-and readdir calls that it makes, in order to cut down on system
-overhead.  However, this also makes it even more susceptible to races,
-especially if the cache or statCache objects are reused between glob
-calls.
-
-Users are thus advised not to use a glob result as a guarantee of
-filesystem state in the face of rapid changes.  For the vast majority
-of operations, this is never a problem.

-# minimatch
-
-A minimal matching utility.
-
-[![Build Status](https://secure.travis-ci.org/isaacs/minimatch.svg)](http://travis-ci.org/isaacs/minimatch)
-
-
-This is the matching library used internally by npm.
-
-It works by converting glob expressions into JavaScript `RegExp`
-objects.
-
-## Usage
-
-```javascript
-var minimatch = require("minimatch")
-
-minimatch("bar.foo", "*.foo") // true!
-minimatch("bar.foo", "*.bar") // false!
-minimatch("bar.foo", "*.+(bar|foo)", { debug: true }) // true, and noisy!
-```
-
-## Features
-
-Supports these glob features:
-
-* Brace Expansion
-* Extended glob matching
-* "Globstar" `**` matching
-
-See:
-
-* `man sh`
-* `man bash`
-* `man 3 fnmatch`
-* `man 5 gitignore`
-
-## Minimatch Class
-
-Create a minimatch object by instantiating the `minimatch.Minimatch` class.
-
-```javascript
-var Minimatch = require("minimatch").Minimatch
-var mm = new Minimatch(pattern, options)
-```
-
-### Properties
-
-* `pattern` The original pattern the minimatch object represents.
-* `options` The options supplied to the constructor.
-* `set` A 2-dimensional array of regexp or string expressions.
-  Each row in the
-  array corresponds to a brace-expanded pattern.  Each item in the row
-  corresponds to a single path-part.  For example, the pattern
-  `{a,b/c}/d` would expand to a set of patterns like:
-
-        [ [ a, d ]
-        , [ b, c, d ] ]
-
-    If a portion of the pattern doesn't have any "magic" in it
-    (that is, it's something like `"foo"` rather than `fo*o?`), then it
-    will be left as a string rather than converted to a regular
-    expression.
-
-* `regexp` Created by the `makeRe` method.  A single regular expression
-  expressing the entire pattern.  This is useful in cases where you wish
-  to use the pattern somewhat like `fnmatch(3)` with `FNM_PATH` enabled.
-* `negate` True if the pattern is negated.
-* `comment` True if the pattern is a comment.
-* `empty` True if the pattern is `""`.
-
-### Methods
-
-* `makeRe` Generate the `regexp` member if necessary, and return it.
-  Will return `false` if the pattern is invalid.
-* `match(fname)` Return true if the filename matches the pattern, or
-  false otherwise.
-* `matchOne(fileArray, patternArray, partial)` Take a `/`-split
-  filename, and match it against a single row in the `regExpSet`.  This
-  method is mainly for internal use, but is exposed so that it can be
-  used by a glob-walker that needs to avoid excessive filesystem calls.
-
-All other methods are internal, and will be called as necessary.
-
-### minimatch(path, pattern, options)
-
-Main export.  Tests a path against the pattern using the options.
-
-```javascript
-var isJS = minimatch(file, "*.js", { matchBase: true })
-```
-
-### minimatch.filter(pattern, options)
-
-Returns a function that tests its
-supplied argument, suitable for use with `Array.filter`.  Example:
-
-```javascript
-var javascripts = fileList.filter(minimatch.filter("*.js", {matchBase: true}))
-```
-
-### minimatch.match(list, pattern, options)
-
-Match against the list of
-files, in the style of fnmatch or glob.  If nothing is matched, and
-options.nonull is set, then return a list containing the pattern itself.
-
-```javascript
-var javascripts = minimatch.match(fileList, "*.js", {matchBase: true}))
-```
-
-### minimatch.makeRe(pattern, options)
-
-Make a regular expression object from the pattern.
-
-## Options
-
-All options are `false` by default.
-
-### debug
-
-Dump a ton of stuff to stderr.
-
-### nobrace
-
-Do not expand `{a,b}` and `{1..3}` brace sets.
-
-### noglobstar
-
-Disable `**` matching against multiple folder names.
-
-### dot
-
-Allow patterns to match filenames starting with a period, even if
-the pattern does not explicitly have a period in that spot.
-
-Note that by default, `a/**/b` will **not** match `a/.d/b`, unless `dot`
-is set.
-
-### noext
-
-Disable "extglob" style patterns like `+(a|b)`.
-
-### nocase
-
-Perform a case-insensitive match.
-
-### nonull
-
-When a match is not found by `minimatch.match`, return a list containing
-the pattern itself if this option is set.  When not set, an empty list
-is returned if there are no matches.
-
-### matchBase
-
-If set, then patterns without slashes will be matched
-against the basename of the path if it contains slashes.  For example,
-`a?b` would match the path `/xyz/123/acb`, but not `/xyz/acb/123`.
-
-### nocomment
-
-Suppress the behavior of treating `#` at the start of a pattern as a
-comment.
-
-### nonegate
-
-Suppress the behavior of treating a leading `!` character as negation.
-
-### flipNegate
-
-Returns from negate expressions the same as if they were not negated.
-(Ie, true on a hit, false on a miss.)
-
-
-## Comparisons to other fnmatch/glob implementations
-
-While strict compliance with the existing standards is a worthwhile
-goal, some discrepancies exist between minimatch and other
-implementations, and are intentional.
-
-If the pattern starts with a `!` character, then it is negated.  Set the
-`nonegate` flag to suppress this behavior, and treat leading `!`
-characters normally.  This is perhaps relevant if you wish to start the
-pattern with a negative extglob pattern like `!(a|B)`.  Multiple `!`
-characters at the start of a pattern will negate the pattern multiple
-times.
-
-If a pattern starts with `#`, then it is treated as a comment, and
-will not match anything.  Use `\#` to match a literal `#` at the
-start of a line, or set the `nocomment` flag to suppress this behavior.
-
-The double-star character `**` is supported by default, unless the
-`noglobstar` flag is set.  This is supported in the manner of bsdglob
-and bash 4.1, where `**` only has special significance if it is the only
-thing in a path part.  That is, `a/**/b` will match `a/x/y/b`, but
-`a/**b` will not.
-
-If an escaped pattern has no matches, and the `nonull` flag is set,
-then minimatch.match returns the pattern as-provided, rather than
-interpreting the character escapes.  For example,
-`minimatch.match([], "\\*a\\?")` will return `"\\*a\\?"` rather than
-`"*a?"`.  This is akin to setting the `nullglob` option in bash, except
-that it does not resolve escaped pattern characters.
-
-If brace expansion is not disabled, then it is performed before any
-other interpretation of the glob pattern.  Thus, a pattern like
-`+(a|{b),c)}`, which would not be valid in bash or zsh, is expanded
-**first** into the set of `+(a|b)` and `+(a|c)`, and those patterns are
-checked for validity.  Since those two are valid, matching proceeds.

-
-### Finding problematic bits of code using grep
-
-Just run `grep -nrE '[^a-zA-Z](Slow)?Buffer\s*\(' --exclude-dir node_modules`.
-
-It will find all the potentially unsafe places in your own code (with some considerably unlikely
-exceptions).
-
-### Finding problematic bits of code using Node.js 8
-
-If you’re using Node.js ≥ 8.0.0 (which is recommended), Node.js exposes multiple options that help with finding the relevant pieces of code:
-
-- `--trace-warnings` will make Node.js show a stack trace for this warning and other warnings that are printed by Node.js.
-- `--trace-deprecation` does the same thing, but only for deprecation warnings.
-- `--pending-deprecation` will show more types of deprecation warnings. In particular, it will show the `Buffer()` deprecation warning, even on Node.js 8.
-
-You can set these flags using an environment variable:
-
-```console
-$ export NODE_OPTIONS='--trace-warnings --pending-deprecation'
-$ cat example.js
-'use strict';
-const foo = new Buffer('foo');
-$ node example.js
-(node:7147) [DEP0005] DeprecationWarning: The Buffer() and new Buffer() constructors are not recommended for use due to security and usability concerns. Please use the new Buffer.alloc(), Buffer.allocUnsafe(), or Buffer.from() construction methods instead.
-    at showFlaggedDeprecation (buffer.js:127:13)
-    at new Buffer (buffer.js:148:3)
-    at Object.<anonymous> (/path/to/example.js:2:13)
-    [... more stack trace lines ...]
-```
-
-### Finding problematic bits of code using linters
-
-Eslint rules [no-buffer-constructor](https://eslint.org/docs/rules/no-buffer-constructor)
-or
-[node/no-deprecated-api](https://github.com/mysticatea/eslint-plugin-node/blob/master/docs/rules/no-deprecated-api.md)
-also find calls to deprecated `Buffer()` API. Those rules are included in some pre-sets.
-
-There is a drawback, though, that it doesn't always
-[work correctly](https://github.com/chalker/safer-buffer#why-not-safe-buffer) when `Buffer` is
-overriden e.g. with a polyfill, so recommended is a combination of this and some other method
-described above.
-
-<a id="variant-1"></a>
-## Variant 1: Drop support for Node.js ≤ 4.4.x and 5.0.0 — 5.9.x.
-
-This is the recommended solution nowadays that would imply only minimal overhead.
-
-The Node.js 5.x release line has been unsupported since July 2016, and the Node.js 4.x release line reaches its End of Life in April 2018 (→ [Schedule](https://github.com/nodejs/Release#release-schedule)). This means that these versions of Node.js will *not* receive any updates, even in case of security issues, so using these release lines should be avoided, if at all possible.
-
-What you would do in this case is to convert all `new Buffer()` or `Buffer()` calls to use `Buffer.alloc()` or `Buffer.from()`, in the following way:
-
-- For `new Buffer(number)`, replace it with `Buffer.alloc(number)`.
-- For `new Buffer(string)` (or `new Buffer(string, encoding)`), replace it with `Buffer.from(string)` (or `Buffer.from(string, encoding)`).
-- For all other combinations of arguments (these are much rarer), also replace `new Buffer(...arguments)` with `Buffer.from(...arguments)`.
-
-Note that `Buffer.alloc()` is also _faster_ on the current Node.js versions than
-`new Buffer(size).fill(0)`, which is what you would otherwise need to ensure zero-filling.
-
-Enabling eslint rule [no-buffer-constructor](https://eslint.org/docs/rules/no-buffer-constructor)
-or
-[node/no-deprecated-api](https://github.com/mysticatea/eslint-plugin-node/blob/master/docs/rules/no-deprecated-api.md)
-is recommended to avoid accidential unsafe Buffer API usage.
-
-There is also a [JSCodeshift codemod](https://github.com/joyeecheung/node-dep-codemod#dep005)
-for automatically migrating Buffer constructors to `Buffer.alloc()` or `Buffer.from()`.
-Note that it currently only works with cases where the arguments are literals or where the
-constructor is invoked with two arguments.
-
-_If you currently support those older Node.js versions and dropping them would be a semver-major change
-for you, or if you support older branches of your packages, consider using [Variant 2](#variant-2)
-or [Variant 3](#variant-3) on older branches, so people using those older branches will also receive
-the fix. That way, you will eradicate potential issues caused by unguarded Buffer API usage and
-your users will not observe a runtime deprecation warning when running your code on Node.js 10._
-
-<a id="variant-2"></a>
-## Variant 2: Use a polyfill
-
-Utilize [safer-buffer](https://www.npmjs.com/package/safer-buffer) as a polyfill to support older
-Node.js versions.
-
-You would take exacly the same steps as in [Variant 1](#variant-1), but with a polyfill
-`const Buffer = require('safer-buffer').Buffer` in all files where you use the new `Buffer` api.
-
-Make sure that you do not use old `new Buffer` API — in any files where the line above is added,
-using old `new Buffer()` API will _throw_. It will be easy to notice that in CI, though.
-
-Alternatively, you could use [buffer-from](https://www.npmjs.com/package/buffer-from) and/or
-[buffer-alloc](https://www.npmjs.com/package/buffer-alloc) [ponyfills](https://ponyfill.com/) —
-those are great, the only downsides being 4 deps in the tree and slightly more code changes to
-migrate off them (as you would be using e.g. `Buffer.from` under a different name). If you need only
-`Buffer.from` polyfilled — `buffer-from` alone which comes with no extra dependencies.
-
-_Alternatively, you could use [safe-buffer](https://www.npmjs.com/package/safe-buffer) — it also
-provides a polyfill, but takes a different approach which has
-[it's drawbacks](https://github.com/chalker/safer-buffer#why-not-safe-buffer). It will allow you
-to also use the older `new Buffer()` API in your code, though — but that's arguably a benefit, as
-it is problematic, can cause issues in your code, and will start emitting runtime deprecation
-warnings starting with Node.js 10._
-
-Note that in either case, it is important that you also remove all calls to the old Buffer
-API manually — just throwing in `safe-buffer` doesn't fix the problem by itself, it just provides
-a polyfill for the new API. I have seen people doing that mistake.
-
-Enabling eslint rule [no-buffer-constructor](https://eslint.org/docs/rules/no-buffer-constructor)
-or
-[node/no-deprecated-api](https://github.com/mysticatea/eslint-plugin-node/blob/master/docs/rules/no-deprecated-api.md)
-is recommended.
-
-_Don't forget to drop the polyfill usage once you drop support for Node.js < 4.5.0._
-
-<a id="variant-3"></a>
-## Variant 3 — manual detection, with safeguards
-
-This is useful if you create Buffer instances in only a few places (e.g. one), or you have your own
-wrapper around them.
-
-### Buffer(0)
-
-This special case for creating empty buffers can be safely replaced with `Buffer.concat([])`, which
-returns the same result all the way down to Node.js 0.8.x.
-
-### Buffer(notNumber)
-
-Before:
-
-```js
-var buf = new Buffer(notNumber, encoding);
-```
-
-After:
-
-```js
-var buf;
-if (Buffer.from && Buffer.from !== Uint8Array.from) {
-  buf = Buffer.from(notNumber, encoding);
-} else {
-  if (typeof notNumber === 'number')
-    throw new Error('The "size" argument must be of type number.');
-  buf = new Buffer(notNumber, encoding);
-}
-```
-
-`encoding` is optional.
-
-Note that the `typeof notNumber` before `new Buffer` is required (for cases when `notNumber` argument is not
-hard-coded) and _is not caused by the deprecation of Buffer constructor_ — it's exactly _why_ the
-Buffer constructor is deprecated. Ecosystem packages lacking this type-check caused numereous
-security issues — situations when unsanitized user input could end up in the `Buffer(arg)` create
-problems ranging from DoS to leaking sensitive information to the attacker from the process memory.
-
-When `notNumber` argument is hardcoded (e.g. literal `"abc"` or `[0,1,2]`), the `typeof` check can
-be omitted.
-
-Also note that using TypeScript does not fix this problem for you — when libs written in
-`TypeScript` are used from JS, or when user input ends up there — it behaves exactly as pure JS, as
-all type checks are translation-time only and are not present in the actual JS code which TS
-compiles to.
-
-### Buffer(number)
-
-For Node.js 0.10.x (and below) support:
-
-```js
-var buf;
-if (Buffer.alloc) {
-  buf = Buffer.alloc(number);
-} else {
-  buf = new Buffer(number);
-  buf.fill(0);
-}
-```
-
-Otherwise (Node.js ≥ 0.12.x):
-
-```js
-const buf = Buffer.alloc ? Buffer.alloc(number) : new Buffer(number).fill(0);
-```
-
-## Regarding Buffer.allocUnsafe
-
-Be extra cautious when using `Buffer.allocUnsafe`:
- * Don't use it if you don't have a good reason to
-   * e.g. you probably won't ever see a performance difference for small buffers, in fact, those
-     might be even faster with `Buffer.alloc()`,
-   * if your code is not in the hot code path — you also probably won't notice a difference,
-   * keep in mind that zero-filling minimizes the potential risks.
- * If you use it, make sure that you never return the buffer in a partially-filled state,
-   * if you are writing to it sequentially — always truncate it to the actuall written length
-
-Errors in handling buffers allocated with `Buffer.allocUnsafe` could result in various issues,
-ranged from undefined behaviour of your code to sensitive data (user input, passwords, certs)
-leaking to the remote attacker.
-
-_Note that the same applies to `new Buffer` usage without zero-filling, depending on the Node.js
-version (and lacking type checks also adds DoS to the list of potential problems)._

-## FAQ
-
-<a id="design-flaws"></a>
-### What is wrong with the `Buffer` constructor?
-
-The `Buffer` constructor could be used to create a buffer in many different ways:
-
-- `new Buffer(42)` creates a `Buffer` of 42 bytes. Before Node.js 8, this buffer contained
-  *arbitrary memory* for performance reasons, which could include anything ranging from
-  program source code to passwords and encryption keys.
-- `new Buffer('abc')` creates a `Buffer` that contains the UTF-8-encoded version of
-  the string `'abc'`. A second argument could specify another encoding: For example,
-  `new Buffer(string, 'base64')` could be used to convert a Base64 string into the original
-  sequence of bytes that it represents.
-- There are several other combinations of arguments.
-
-This meant that, in code like `var buffer = new Buffer(foo);`, *it is not possible to tell
-what exactly the contents of the generated buffer are* without knowing the type of `foo`.
-
-Sometimes, the value of `foo` comes from an external source. For example, this function
-could be exposed as a service on a web server, converting a UTF-8 string into its Base64 form:
-
-```
-function stringToBase64(req, res) {
-  // The request body should have the format of `{ string: 'foobar' }`
-  const rawBytes = new Buffer(req.body.string)
-  const encoded = rawBytes.toString('base64')
-  res.end({ encoded: encoded })
-}
-```
-
-Note that this code does *not* validate the type of `req.body.string`:
-
-- `req.body.string` is expected to be a string. If this is the case, all goes well.
-- `req.body.string` is controlled by the client that sends the request.
-- If `req.body.string` is the *number* `50`, the `rawBytes` would be 50 bytes:
-  - Before Node.js 8, the content would be uninitialized
-  - After Node.js 8, the content would be `50` bytes with the value `0`
-
-Because of the missing type check, an attacker could intentionally send a number
-as part of the request. Using this, they can either:
-
-- Read uninitialized memory. This **will** leak passwords, encryption keys and other
-  kinds of sensitive information. (Information leak)
-- Force the program to allocate a large amount of memory. For example, when specifying
-  `500000000` as the input value, each request will allocate 500MB of memory.
-  This can be used to either exhaust the memory available of a program completely
-  and make it crash, or slow it down significantly. (Denial of Service)
-
-Both of these scenarios are considered serious security issues in a real-world
-web server context.
-
-when using `Buffer.from(req.body.string)` instead, passing a number will always
-throw an exception instead, giving a controlled behaviour that can always be
-handled by the program.
-
-<a id="ecosystem-usage"></a>
-### The `Buffer()` constructor has been deprecated for a while. Is this really an issue?
-
-Surveys of code in the `npm` ecosystem have shown that the `Buffer()` constructor is still
-widely used. This includes new code, and overall usage of such code has actually been
-*increasing*.

-Modern Buffer API polyfill without footguns, working on Node.js from 0.8 to current.
-
-## How to use?
-
-First, port all `Buffer()` and `new Buffer()` calls to `Buffer.alloc()` and `Buffer.from()` API.
-
-Then, to achieve compatibility with outdated Node.js versions (`<4.5.0` and 5.x `<5.9.0`), use
-`const Buffer = require('safer-buffer').Buffer` in all files where you make calls to the new
-Buffer API. _Use `var` instead of `const` if you need that for your Node.js version range support._
-
-Also, see the
-[porting Buffer](https://github.com/ChALkeR/safer-buffer/blob/master/Porting-Buffer.md) guide.
-
-## Do I need it?
-
-Hopefully, not — dropping support for outdated Node.js versions should be fine nowdays, and that
-is the recommended path forward. You _do_ need to port to the `Buffer.alloc()` and `Buffer.from()`
-though.
-
-See the [porting guide](https://github.com/ChALkeR/safer-buffer/blob/master/Porting-Buffer.md)
-for a better description.
-
-## Why not [safe-buffer](https://npmjs.com/safe-buffer)?
-
-_In short: while `safe-buffer` serves as a polyfill for the new API, it allows old API usage and
-itself contains footguns._
-
-`safe-buffer` could be used safely to get the new API while still keeping support for older
-Node.js versions (like this module), but while analyzing ecosystem usage of the old Buffer API
-I found out that `safe-buffer` is itself causing problems in some cases.
-
-For example, consider the following snippet:
-
-```console
-$ cat example.unsafe.js
-console.log(Buffer(20))
-$ ./node-v6.13.0-linux-x64/bin/node example.unsafe.js
-<Buffer 0a 00 00 00 00 00 00 00 28 13 de 02 00 00 00 00 05 00 00 00>
-$ standard example.unsafe.js
-standard: Use JavaScript Standard Style (https://standardjs.com)
-  /home/chalker/repo/safer-buffer/example.unsafe.js:2:13: 'Buffer()' was deprecated since v6. Use 'Buffer.alloc()' or 'Buffer.from()' (use 'https://www.npmjs.com/package/safe-buffer' for '<4.5.0') instead.
-```
-
-This is allocates and writes to console an uninitialized chunk of memory.
-[standard](https://www.npmjs.com/package/standard) linter (among others) catch that and warn people
-to avoid using unsafe API.
-
-Let's now throw in `safe-buffer`!
-
-```console
-$ cat example.safe-buffer.js
-const Buffer = require('safe-buffer').Buffer
-console.log(Buffer(20))
-$ standard example.safe-buffer.js
-$ ./node-v6.13.0-linux-x64/bin/node example.safe-buffer.js
-<Buffer 08 00 00 00 00 00 00 00 28 58 01 82 fe 7f 00 00 00 00 00 00>
-```
-
-See the problem? Adding in `safe-buffer` _magically removes the lint warning_, but the behavior
-remains identiсal to what we had before, and when launched on Node.js 6.x LTS — this dumps out
-chunks of uninitialized memory.
-_And this code will still emit runtime warnings on Node.js 10.x and above._
-
-That was done by design. I first considered changing `safe-buffer`, prohibiting old API usage or
-emitting warnings on it, but that significantly diverges from `safe-buffer` design. After some
-discussion, it was decided to move my approach into a separate package, and _this is that separate
-package_.
-
-This footgun is not imaginary — I observed top-downloaded packages doing that kind of thing,
-«fixing» the lint warning by blindly including `safe-buffer` without any actual changes.
-
-Also in some cases, even if the API _was_ migrated to use of safe Buffer API — a random pull request
-can bring unsafe Buffer API usage back to the codebase by adding new calls — and that could go
-unnoticed even if you have a linter prohibiting that (becase of the reason stated above), and even
-pass CI. _I also observed that being done in popular packages._
-
-Some examples:
- * [webdriverio](https://github.com/webdriverio/webdriverio/commit/05cbd3167c12e4930f09ef7cf93b127ba4effae4#diff-124380949022817b90b622871837d56cR31)
-   (a module with 548 759 downloads/month),
- * [websocket-stream](https://github.com/maxogden/websocket-stream/commit/c9312bd24d08271687d76da0fe3c83493871cf61)
-   (218 288 d/m, fix in [maxogden/websocket-stream#142](https://github.com/maxogden/websocket-stream/pull/142)),
- * [node-serialport](https://github.com/node-serialport/node-serialport/commit/e8d9d2b16c664224920ce1c895199b1ce2def48c)
-   (113 138 d/m, fix in [node-serialport/node-serialport#1510](https://github.com/node-serialport/node-serialport/pull/1510)),
- * [karma](https://github.com/karma-runner/karma/commit/3d94b8cf18c695104ca195334dc75ff054c74eec)
-   (3 973 193 d/m, fix in [karma-runner/karma#2947](https://github.com/karma-runner/karma/pull/2947)),
- * [spdy-transport](https://github.com/spdy-http2/spdy-transport/commit/5375ac33f4a62a4f65bcfc2827447d42a5dbe8b1)
-   (5 970 727 d/m, fix in [spdy-http2/spdy-transport#53](https://github.com/spdy-http2/spdy-transport/pull/53)).
- * And there are a lot more over the ecosystem.
-
-I filed a PR at
-[mysticatea/eslint-plugin-node#110](https://github.com/mysticatea/eslint-plugin-node/pull/110) to
-partially fix that (for cases when that lint rule is used), but it is a semver-major change for
-linter rules and presets, so it would take significant time for that to reach actual setups.
-_It also hasn't been released yet (2018-03-20)._
-
-Also, `safer-buffer` discourages the usage of `.allocUnsafe()`, which is often done by a mistake.
-It still supports it with an explicit concern barier, by placing it under
-`require('safer-buffer/dangereous')`.
-
-## But isn't throwing bad?
-
-Not really. It's an error that could be noticed and fixed early, instead of causing havoc later like
-unguarded `new Buffer()` calls that end up receiving user input can do.
-
-This package affects only the files where `var Buffer = require('safer-buffer').Buffer` was done, so
-it is really simple to keep track of things and make sure that you don't mix old API usage with that.
-Also, CI should hint anything that you might have missed.
-
-New commits, if tested, won't land new usage of unsafe Buffer API this way.
-_Node.js 10.x also deals with that by printing a runtime depecation warning._
-
-### Would it affect third-party modules?
-
-No, unless you explicitly do an awful thing like monkey-patching or overriding the built-in `Buffer`.
-Don't do that.
-
-### But I don't want throwing…
-
-That is also fine!
-
-Also, it could be better in some cases when you don't comprehensive enough test coverage.
-
-In that case — just don't override `Buffer` and use
-`var SaferBuffer = require('safer-buffer').Buffer` instead.
-
-That way, everything using `Buffer` natively would still work, but there would be two drawbacks:
-
-* `Buffer.from`/`Buffer.alloc` won't be polyfilled — use `SaferBuffer.from` and
-  `SaferBuffer.alloc` instead.
-* You are still open to accidentally using the insecure deprecated API — use a linter to catch that.
-
-Note that using a linter to catch accidential `Buffer` constructor usage in this case is strongly
-recommended. `Buffer` is not overriden in this usecase, so linters won't get confused.
-
-## «Without footguns»?
-
-Well, it is still possible to do _some_ things with `Buffer` API, e.g. accessing `.buffer` property
-on older versions and duping things from there. You shouldn't do that in your code, probabably.
-
-The intention is to remove the most significant footguns that affect lots of packages in the
-ecosystem, and to do it in the proper way.
-
-Also, this package doesn't protect against security issues affecting some Node.js versions, so for
-usage in your own production code, it is still recommended to update to a Node.js version
-[supported by upstream](https://github.com/nodejs/release#release-schedule).

-# Glob
-
-Match files using the patterns the shell uses, like stars and stuff.
-
-[![Build Status](https://travis-ci.org/isaacs/node-glob.svg?branch=master)](https://travis-ci.org/isaacs/node-glob/) [![Build Status](https://ci.appveyor.com/api/projects/status/kd7f3yftf7unxlsx?svg=true)](https://ci.appveyor.com/project/isaacs/node-glob) [![Coverage Status](https://coveralls.io/repos/isaacs/node-glob/badge.svg?branch=master&service=github)](https://coveralls.io/github/isaacs/node-glob?branch=master)
-
-This is a glob implementation in JavaScript.  It uses the `minimatch`
-library to do its matching.
-
-![](logo/glob.png)
-
-## Usage
-
-Install with npm
-
-```
-npm i glob
-```
-
-```javascript
-var glob = require("glob")
-
-// options is optional
-glob("**/*.js", options, function (er, files) {
-  // files is an array of filenames.
-  // If the `nonull` option is set, and nothing
-  // was found, then files is ["**/*.js"]
-  // er is an error object or null.
-})
-```
-
-## Glob Primer
-
-"Globs" are the patterns you type when you do stuff like `ls *.js` on
-the command line, or put `build/*` in a `.gitignore` file.
-
-Before parsing the path part patterns, braced sections are expanded
-into a set.  Braced sections start with `{` and end with `}`, with any
-number of comma-delimited sections within.  Braced sections may contain
-slash characters, so `a{/b/c,bcd}` would expand into `a/b/c` and `abcd`.
-
-The following characters have special magic meaning when used in a
-path portion:
-
-* `*` Matches 0 or more characters in a single path portion
-* `?` Matches 1 character
-* `[...]` Matches a range of characters, similar to a RegExp range.
-  If the first character of the range is `!` or `^` then it matches
-  any character not in the range.
-* `!(pattern|pattern|pattern)` Matches anything that does not match
-  any of the patterns provided.
-* `?(pattern|pattern|pattern)` Matches zero or one occurrence of the
-  patterns provided.
-* `+(pattern|pattern|pattern)` Matches one or more occurrences of the
-  patterns provided.
-* `*(a|b|c)` Matches zero or more occurrences of the patterns provided
-* `@(pattern|pat*|pat?erN)` Matches exactly one of the patterns
-  provided
-* `**` If a "globstar" is alone in a path portion, then it matches
-  zero or more directories and subdirectories searching for matches.
-  It does not crawl symlinked directories.
-
-### Dots
-
-If a file or directory path portion has a `.` as the first character,
-then it will not match any glob pattern unless that pattern's
-corresponding path part also has a `.` as its first character.
-
-For example, the pattern `a/.*/c` would match the file at `a/.b/c`.
-However the pattern `a/*/c` would not, because `*` does not start with
-a dot character.
-
-You can make glob treat dots as normal characters by setting
-`dot:true` in the options.
-
-### Basename Matching
-
-If you set `matchBase:true` in the options, and the pattern has no
-slashes in it, then it will seek for any file anywhere in the tree
-with a matching basename.  For example, `*.js` would match
-`test/simple/basic.js`.
-
-### Empty Sets
-
-If no matching files are found, then an empty array is returned.  This
-differs from the shell, where the pattern itself is returned.  For
-example:
-
-    $ echo a*s*d*f
-    a*s*d*f
-
-To get the bash-style behavior, set the `nonull:true` in the options.
-
-### See Also:
-
-* `man sh`
-* `man bash` (Search for "Pattern Matching")
-* `man 3 fnmatch`
-* `man 5 gitignore`
-* [minimatch documentation](https://github.com/isaacs/minimatch)
-
-## glob.hasMagic(pattern, [options])
-
-Returns `true` if there are any special characters in the pattern, and
-`false` otherwise.
-
-Note that the options affect the results.  If `noext:true` is set in
-the options object, then `+(a|b)` will not be considered a magic
-pattern.  If the pattern has a brace expansion, like `a/{b/c,x/y}`
-then that is considered magical, unless `nobrace:true` is set in the
-options.
-
-## glob(pattern, [options], cb)
-
-* `pattern` `{String}` Pattern to be matched
-* `options` `{Object}`
-* `cb` `{Function}`
-  * `err` `{Error | null}`
-  * `matches` `{Array<String>}` filenames found matching the pattern
-
-Perform an asynchronous glob search.
-
-## glob.sync(pattern, [options])
-
-* `pattern` `{String}` Pattern to be matched
-* `options` `{Object}`
-* return: `{Array<String>}` filenames found matching the pattern
-
-Perform a synchronous glob search.
-
-## Class: glob.Glob
-
-Create a Glob object by instantiating the `glob.Glob` class.
-
-```javascript
-var Glob = require("glob").Glob
-var mg = new Glob(pattern, options, cb)
-```
-
-It's an EventEmitter, and starts walking the filesystem to find matches
-immediately.
-
-### new glob.Glob(pattern, [options], [cb])
-
-* `pattern` `{String}` pattern to search for
-* `options` `{Object}`
-* `cb` `{Function}` Called when an error occurs, or matches are found
-  * `err` `{Error | null}`
-  * `matches` `{Array<String>}` filenames found matching the pattern
-
-Note that if the `sync` flag is set in the options, then matches will
-be immediately available on the `g.found` member.
-
-### Properties
-
-* `minimatch` The minimatch object that the glob uses.
-* `options` The options object passed in.
-* `aborted` Boolean which is set to true when calling `abort()`.  There
-  is no way at this time to continue a glob search after aborting, but
-  you can re-use the statCache to avoid having to duplicate syscalls.
-* `cache` Convenience object.  Each field has the following possible
-  values:
-  * `false` - Path does not exist
-  * `true` - Path exists
-  * `'FILE'` - Path exists, and is not a directory
-  * `'DIR'` - Path exists, and is a directory
-  * `[file, entries, ...]` - Path exists, is a directory, and the
-    array value is the results of `fs.readdir`
-* `statCache` Cache of `fs.stat` results, to prevent statting the same
-  path multiple times.
-* `symlinks` A record of which paths are symbolic links, which is
-  relevant in resolving `**` patterns.
-* `realpathCache` An optional object which is passed to `fs.realpath`
-  to minimize unnecessary syscalls.  It is stored on the instantiated
-  Glob object, and may be re-used.
-
-### Events
-
-* `end` When the matching is finished, this is emitted with all the
-  matches found.  If the `nonull` option is set, and no match was found,
-  then the `matches` list contains the original pattern.  The matches
-  are sorted, unless the `nosort` flag is set.
-* `match` Every time a match is found, this is emitted with the specific
-  thing that matched. It is not deduplicated or resolved to a realpath.
-* `error` Emitted when an unexpected error is encountered, or whenever
-  any fs error occurs if `options.strict` is set.
-* `abort` When `abort()` is called, this event is raised.
-
-### Methods
-
-* `pause` Temporarily stop the search
-* `resume` Resume the search
-* `abort` Stop the search forever
-
-### Options
-
-All the options that can be passed to Minimatch can also be passed to
-Glob to change pattern matching behavior.  Also, some have been added,
-or have glob-specific ramifications.
-
-All options are false by default, unless otherwise noted.
-
-All options are added to the Glob object, as well.
-
-If you are running many `glob` operations, you can pass a Glob object
-as the `options` argument to a subsequent operation to shortcut some
-`stat` and `readdir` calls.  At the very least, you may pass in shared
-`symlinks`, `statCache`, `realpathCache`, and `cache` options, so that
-parallel glob operations will be sped up by sharing information about
-the filesystem.
-
-* `cwd` The current working directory in which to search.  Defaults
-  to `process.cwd()`.
-* `root` The place where patterns starting with `/` will be mounted
-  onto.  Defaults to `path.resolve(options.cwd, "/")` (`/` on Unix
-  systems, and `C:\` or some such on Windows.)
-* `dot` Include `.dot` files in normal matches and `globstar` matches.
-  Note that an explicit dot in a portion of the pattern will always
-  match dot files.
-* `nomount` By default, a pattern starting with a forward-slash will be
-  "mounted" onto the root setting, so that a valid filesystem path is
-  returned.  Set this flag to disable that behavior.
-* `mark` Add a `/` character to directory matches.  Note that this
-  requires additional stat calls.
-* `nosort` Don't sort the results.
-* `stat` Set to true to stat *all* results.  This reduces performance
-  somewhat, and is completely unnecessary, unless `readdir` is presumed
-  to be an untrustworthy indicator of file existence.
-* `silent` When an unusual error is encountered when attempting to
-  read a directory, a warning will be printed to stderr.  Set the
-  `silent` option to true to suppress these warnings.
-* `strict` When an unusual error is encountered when attempting to
-  read a directory, the process will just continue on in search of
-  other matches.  Set the `strict` option to raise an error in these
-  cases.
-* `cache` See `cache` property above.  Pass in a previously generated
-  cache object to save some fs calls.
-* `statCache` A cache of results of filesystem information, to prevent
-  unnecessary stat calls.  While it should not normally be necessary
-  to set this, you may pass the statCache from one glob() call to the
-  options object of another, if you know that the filesystem will not
-  change between calls.  (See "Race Conditions" below.)
-* `symlinks` A cache of known symbolic links.  You may pass in a
-  previously generated `symlinks` object to save `lstat` calls when
-  resolving `**` matches.
-* `sync` DEPRECATED: use `glob.sync(pattern, opts)` instead.
-* `nounique` In some cases, brace-expanded patterns can result in the
-  same file showing up multiple times in the result set.  By default,
-  this implementation prevents duplicates in the result set.  Set this
-  flag to disable that behavior.
-* `nonull` Set to never return an empty set, instead returning a set
-  containing the pattern itself.  This is the default in glob(3).
-* `debug` Set to enable debug logging in minimatch and glob.
-* `nobrace` Do not expand `{a,b}` and `{1..3}` brace sets.
-* `noglobstar` Do not match `**` against multiple filenames.  (Ie,
-  treat it as a normal `*` instead.)
-* `noext` Do not match `+(a|b)` "extglob" patterns.
-* `nocase` Perform a case-insensitive match.  Note: on
-  case-insensitive filesystems, non-magic patterns will match by
-  default, since `stat` and `readdir` will not raise errors.
-* `matchBase` Perform a basename-only match if the pattern does not
-  contain any slash characters.  That is, `*.js` would be treated as
-  equivalent to `**/*.js`, matching all js files in all directories.
-* `nodir` Do not match directories, only files.  (Note: to match
-  *only* directories, simply put a `/` at the end of the pattern.)
-* `ignore` Add a pattern or an array of glob patterns to exclude matches.
-  Note: `ignore` patterns are *always* in `dot:true` mode, regardless
-  of any other settings.
-* `follow` Follow symlinked directories when expanding `**` patterns.
-  Note that this can result in a lot of duplicate references in the
-  presence of cyclic links.
-* `realpath` Set to true to call `fs.realpath` on all of the results.
-  In the case of a symlink that cannot be resolved, the full absolute
-  path to the matched entry is returned (though it will usually be a
-  broken symlink)
-* `absolute` Set to true to always receive absolute paths for matched
-  files.  Unlike `realpath`, this also affects the values returned in
-  the `match` event.
-
-## Comparisons to other fnmatch/glob implementations
-
-While strict compliance with the existing standards is a worthwhile
-goal, some discrepancies exist between node-glob and other
-implementations, and are intentional.
-
-The double-star character `**` is supported by default, unless the
-`noglobstar` flag is set.  This is supported in the manner of bsdglob
-and bash 4.3, where `**` only has special significance if it is the only
-thing in a path part.  That is, `a/**/b` will match `a/x/y/b`, but
-`a/**b` will not.
-
-Note that symlinked directories are not crawled as part of a `**`,
-though their contents may match against subsequent portions of the
-pattern.  This prevents infinite loops and duplicates and the like.
-
-If an escaped pattern has no matches, and the `nonull` flag is set,
-then glob returns the pattern as-provided, rather than
-interpreting the character escapes.  For example,
-`glob.match([], "\\*a\\?")` will return `"\\*a\\?"` rather than
-`"*a?"`.  This is akin to setting the `nullglob` option in bash, except
-that it does not resolve escaped pattern characters.
-
-If brace expansion is not disabled, then it is performed before any
-other interpretation of the glob pattern.  Thus, a pattern like
-`+(a|{b),c)}`, which would not be valid in bash or zsh, is expanded
-**first** into the set of `+(a|b)` and `+(a|c)`, and those patterns are
-checked for validity.  Since those two are valid, matching proceeds.
-

-Previously, this module let you mark a pattern as a "comment" if it
-started with a `#` character, or a "negated" pattern if it started
-with a `!` character.
-
-These options were deprecated in version 5, and removed in version 6.
-
-To specify things that should not match, use the `ignore` option.
-
-## Windows
-
-**Please only use forward-slashes in glob expressions.**
-
-Though windows uses either `/` or `\` as its path separator, only `/`
-characters are used by this glob implementation.  You must use
-forward-slashes **only** in glob expressions.  Back-slashes will always
-be interpreted as escape characters, not path separators.
-
-Results from absolute patterns such as `/foo/*` are mounted onto the
-root setting using `path.join`.  On windows, this will by default result
-in `/foo/*` matching `C:\foo\bar.txt`.
-
-## Race Conditions
-
-Glob searching, by its very nature, is susceptible to race conditions,
-since it relies on directory walking and such.
-
-As a result, it is possible that a file that exists when glob looks for
-it may have been deleted or modified by the time it returns the result.
-
-As part of its internal implementation, this program caches all stat
-and readdir calls that it makes, in order to cut down on system
-overhead.  However, this also makes it even more susceptible to races,
-especially if the cache or statCache objects are reused between glob
-calls.
-
-Users are thus advised not to use a glob result as a guarantee of
-filesystem state in the face of rapid changes.  For the vast majority
-of operations, this is never a problem.

-   * Creates a `lodash` object which wraps `value` to enable implicit method
-   * chain sequences. Methods that operate on and return arrays, collections,
-   * and functions can be chained together. Methods that retrieve a single value
-   * or may return a primitive value will automatically end the chain sequence
-   * and return the unwrapped value. Otherwise, the value must be unwrapped
-   * with `_#value`.
-   *
-   * Explicit chain sequences, which must be unwrapped with `_#value`, may be
-   * enabled using `_.chain`.
-   *
-   * The execution of chained methods is lazy, that is, it's deferred until
-   * `_#value` is implicitly or explicitly called.
-   *
-   * Lazy evaluation allows several methods to support shortcut fusion.
-   * Shortcut fusion is an optimization to merge iteratee calls; this avoids
-   * the creation of intermediate arrays and can greatly reduce the number of
-   * iteratee executions. Sections of a chain sequence qualify for shortcut
-   * fusion if the section is applied to an array and iteratees accept only
-   * one argument. The heuristic for whether a section qualifies for shortcut
-   * fusion is subject to change.
-   *
-   * Chaining is supported in custom builds as long as the `_#value` method is
-   * directly or indirectly included in the build.
-   *
-   * In addition to lodash methods, wrappers have `Array` and `String` methods.
-   *
-   * The wrapper `Array` methods are:
-   * `concat`, `join`, `pop`, `push`, `shift`, `sort`, `splice`, and `unshift`
-   *
-   * The wrapper `String` methods are:
-   * `replace` and `split`
-   *
-   * The wrapper methods that support shortcut fusion are:
-   * `at`, `compact`, `drop`, `dropRight`, `dropWhile`, `filter`, `find`,
-   * `findLast`, `head`, `initial`, `last`, `map`, `reject`, `reverse`, `slice`,
-   * `tail`, `take`, `takeRight`, `takeRightWhile`, `takeWhile`, and `toArray`
-   *
-   * The chainable wrapper methods are:
-   * `after`, `ary`, `assign`, `assignIn`, `assignInWith`, `assignWith`, `at`,
-   * `before`, `bind`, `bindAll`, `bindKey`, `castArray`, `chain`, `chunk`,
-   * `commit`, `compact`, `concat`, `conforms`, `constant`, `countBy`, `create`,
-   * `curry`, `debounce`, `defaults`, `defaultsDeep`, `defer`, `delay`,
-   * `difference`, `differenceBy`, `differenceWith`, `drop`, `dropRight`,
-   * `dropRightWhile`, `dropWhile`, `extend`, `extendWith`, `fill`, `filter`,
-   * `flatMap`, `flatMapDeep`, `flatMapDepth`, `flatten`, `flattenDeep`,

-   * `nthArg`, `omit`, `omitBy`, `once`, `orderBy`, `over`, `overArgs`,
-   * `overEvery`, `overSome`, `partial`, `partialRight`, `partition`, `pick`,
-   * `pickBy`, `plant`, `property`, `propertyOf`, `pull`, `pullAll`, `pullAllBy`,
-   * `pullAllWith`, `pullAt`, `push`, `range`, `rangeRight`, `rearg`, `reject`,

- * Creates a debounced function that delays invoking `func` until after `wait`

- * delayed `func` invocations and a `flush` method to immediately invoke them.
- * Provide `options` to indicate whether `func` should be invoked on the
- * leading and/or trailing edge of the `wait` timeout. The `func` is invoked

- *
- * **Note:** If `leading` and `trailing` options are `true`, `func` is
- * invoked on the trailing edge of the timeout only if the debounced function
- * is invoked more than once during the `wait` timeout.
- *
- * If `wait` is `0` and `leading` is `false`, `func` invocation is deferred

-     * Creates a `lodash` object which wraps `value` to enable implicit method
-     * chain sequences. Methods that operate on and return arrays, collections,
-     * and functions can be chained together. Methods that retrieve a single value
-     * or may return a primitive value will automatically end the chain sequence
-     * and return the unwrapped value. Otherwise, the value must be unwrapped
-     * with `_#value`.
-     *
-     * Explicit chain sequences, which must be unwrapped with `_#value`, may be
-     * enabled using `_.chain`.
-     *
-     * The execution of chained methods is lazy, that is, it's deferred until
-     * `_#value` is implicitly or explicitly called.
-     *
-     * Lazy evaluation allows several methods to support shortcut fusion.
-     * Shortcut fusion is an optimization to merge iteratee calls; this avoids
-     * the creation of intermediate arrays and can greatly reduce the number of
-     * iteratee executions. Sections of a chain sequence qualify for shortcut
-     * fusion if the section is applied to an array and iteratees accept only
-     * one argument. The heuristic for whether a section qualifies for shortcut
-     * fusion is subject to change.
-     *
-     * Chaining is supported in custom builds as long as the `_#value` method is
-     * directly or indirectly included in the build.
-     *
-     * In addition to lodash methods, wrappers have `Array` and `String` methods.
-     *
-     * The wrapper `Array` methods are:
-     * `concat`, `join`, `pop`, `push`, `shift`, `sort`, `splice`, and `unshift`
-     *
-     * The wrapper `String` methods are:
-     * `replace` and `split`
-     *
-     * The wrapper methods that support shortcut fusion are:
-     * `at`, `compact`, `drop`, `dropRight`, `dropWhile`, `filter`, `find`,
-     * `findLast`, `head`, `initial`, `last`, `map`, `reject`, `reverse`, `slice`,
-     * `tail`, `take`, `takeRight`, `takeRightWhile`, `takeWhile`, and `toArray`
-     *
-     * The chainable wrapper methods are:
-     * `after`, `ary`, `assign`, `assignIn`, `assignInWith`, `assignWith`, `at`,
-     * `before`, `bind`, `bindAll`, `bindKey`, `castArray`, `chain`, `chunk`,

- * Creates a `lodash` object which wraps `value` to enable implicit method

- * or may return a primitive value will automatically end the chain sequence
- * and return the unwrapped value. Otherwise, the value must be unwrapped
- * with `_#value`.
- *
- * Explicit chain sequences, which must be unwrapped with `_#value`, may be

- * The execution of chained methods is lazy, that is, it's deferred until
- * `_#value` is implicitly or explicitly called.
- *
- * Lazy evaluation allows several methods to support shortcut fusion.
- * Shortcut fusion is an optimization to merge iteratee calls; this avoids
- * the creation of intermediate arrays and can greatly reduce the number of
- * iteratee executions. Sections of a chain sequence qualify for shortcut
- * fusion if the section is applied to an array and iteratees accept only
- * one argument. The heuristic for whether a section qualifies for shortcut
- * fusion is subject to change.
- *
- * Chaining is supported in custom builds as long as the `_#value` method is
- * directly or indirectly included in the build.
- *
- * In addition to lodash methods, wrappers have `Array` and `String` methods.

- * The wrapper `Array` methods are:
- * `concat`, `join`, `pop`, `push`, `shift`, `sort`, `splice`, and `unshift`

-# minimatch
-
-A minimal matching utility.
-
-[![Build Status](https://secure.travis-ci.org/isaacs/minimatch.svg)](http://travis-ci.org/isaacs/minimatch)
-
-
-This is the matching library used internally by npm.
-
-It works by converting glob expressions into JavaScript `RegExp`
-objects.
-
-## Usage
-
-```javascript
-var minimatch = require("minimatch")
-
-minimatch("bar.foo", "*.foo") // true!
-minimatch("bar.foo", "*.bar") // false!
-minimatch("bar.foo", "*.+(bar|foo)", { debug: true }) // true, and noisy!
-```
-
-## Features
-
-Supports these glob features:
-
-* Brace Expansion
-* Extended glob matching
-* "Globstar" `**` matching
-
-See:
-
-* `man sh`
-* `man bash`
-* `man 3 fnmatch`
-* `man 5 gitignore`
-
-## Minimatch Class
-
-Create a minimatch object by instantiating the `minimatch.Minimatch` class.
-
-```javascript
-var Minimatch = require("minimatch").Minimatch
-var mm = new Minimatch(pattern, options)
-```
-
-### Properties
-
-* `pattern` The original pattern the minimatch object represents.
-* `options` The options supplied to the constructor.
-* `set` A 2-dimensional array of regexp or string expressions.
-  Each row in the
-  array corresponds to a brace-expanded pattern.  Each item in the row
-  corresponds to a single path-part.  For example, the pattern
-  `{a,b/c}/d` would expand to a set of patterns like:
-
-        [ [ a, d ]
-        , [ b, c, d ] ]
-
-    If a portion of the pattern doesn't have any "magic" in it
-    (that is, it's something like `"foo"` rather than `fo*o?`), then it
-    will be left as a string rather than converted to a regular
-    expression.
-
-* `regexp` Created by the `makeRe` method.  A single regular expression
-  expressing the entire pattern.  This is useful in cases where you wish
-  to use the pattern somewhat like `fnmatch(3)` with `FNM_PATH` enabled.
-* `negate` True if the pattern is negated.
-* `comment` True if the pattern is a comment.
-* `empty` True if the pattern is `""`.
-
-### Methods
-
-* `makeRe` Generate the `regexp` member if necessary, and return it.
-  Will return `false` if the pattern is invalid.
-* `match(fname)` Return true if the filename matches the pattern, or
-  false otherwise.
-* `matchOne(fileArray, patternArray, partial)` Take a `/`-split
-  filename, and match it against a single row in the `regExpSet`.  This
-  method is mainly for internal use, but is exposed so that it can be
-  used by a glob-walker that needs to avoid excessive filesystem calls.
-
-All other methods are internal, and will be called as necessary.
-
-### minimatch(path, pattern, options)
-
-Main export.  Tests a path against the pattern using the options.
-
-```javascript
-var isJS = minimatch(file, "*.js", { matchBase: true })
-```
-
-### minimatch.filter(pattern, options)
-
-Returns a function that tests its
-supplied argument, suitable for use with `Array.filter`.  Example:
-
-```javascript
-var javascripts = fileList.filter(minimatch.filter("*.js", {matchBase: true}))
-```
-
-### minimatch.match(list, pattern, options)
-
-Match against the list of
-files, in the style of fnmatch or glob.  If nothing is matched, and
-options.nonull is set, then return a list containing the pattern itself.
-
-```javascript
-var javascripts = minimatch.match(fileList, "*.js", {matchBase: true}))
-```
-
-### minimatch.makeRe(pattern, options)
-
-Make a regular expression object from the pattern.
-
-## Options
-
-All options are `false` by default.
-
-### debug
-
-Dump a ton of stuff to stderr.
-
-### nobrace
-
-Do not expand `{a,b}` and `{1..3}` brace sets.
-
-### noglobstar
-
-Disable `**` matching against multiple folder names.
-
-### dot
-
-Allow patterns to match filenames starting with a period, even if
-the pattern does not explicitly have a period in that spot.
-
-Note that by default, `a/**/b` will **not** match `a/.d/b`, unless `dot`
-is set.
-
-### noext
-
-Disable "extglob" style patterns like `+(a|b)`.
-
-### nocase
-
-Perform a case-insensitive match.
-
-### nonull
-
-When a match is not found by `minimatch.match`, return a list containing
-the pattern itself if this option is set.  When not set, an empty list
-is returned if there are no matches.
-
-### matchBase
-
-If set, then patterns without slashes will be matched
-against the basename of the path if it contains slashes.  For example,
-`a?b` would match the path `/xyz/123/acb`, but not `/xyz/acb/123`.
-
-### nocomment
-
-Suppress the behavior of treating `#` at the start of a pattern as a
-comment.
-
-### nonegate
-
-Suppress the behavior of treating a leading `!` character as negation.
-
-### flipNegate
-
-Returns from negate expressions the same as if they were not negated.
-(Ie, true on a hit, false on a miss.)
-
-
-## Comparisons to other fnmatch/glob implementations
-
-While strict compliance with the existing standards is a worthwhile
-goal, some discrepancies exist between minimatch and other
-implementations, and are intentional.
-
-If the pattern starts with a `!` character, then it is negated.  Set the
-`nonegate` flag to suppress this behavior, and treat leading `!`
-characters normally.  This is perhaps relevant if you wish to start the
-pattern with a negative extglob pattern like `!(a|B)`.  Multiple `!`
-characters at the start of a pattern will negate the pattern multiple
-times.
-
-If a pattern starts with `#`, then it is treated as a comment, and
-will not match anything.  Use `\#` to match a literal `#` at the
-start of a line, or set the `nocomment` flag to suppress this behavior.
-
-The double-star character `**` is supported by default, unless the
-`noglobstar` flag is set.  This is supported in the manner of bsdglob
-and bash 4.1, where `**` only has special significance if it is the only
-thing in a path part.  That is, `a/**/b` will match `a/x/y/b`, but
-`a/**b` will not.
-
-If an escaped pattern has no matches, and the `nonull` flag is set,
-then minimatch.match returns the pattern as-provided, rather than
-interpreting the character escapes.  For example,
-`minimatch.match([], "\\*a\\?")` will return `"\\*a\\?"` rather than
-`"*a?"`.  This is akin to setting the `nullglob` option in bash, except
-that it does not resolve escaped pattern characters.
-
-If brace expansion is not disabled, then it is performed before any
-other interpretation of the glob pattern.  Thus, a pattern like
-`+(a|{b),c)}`, which would not be valid in bash or zsh, is expanded
-**first** into the set of `+(a|b)` and `+(a|c)`, and those patterns are
-checked for validity.  Since those two are valid, matching proceeds.

-[![devDependency Status](https://david-dm.org/xzyfer/sass-graph/dev-status.svg?theme=shields.io)](https://david-dm.org/xzyfer/sass-graph#info=devDependencies)
-
-## Install
-
-Install with [npm](https://npmjs.org/package/sass-graph)
-
-```
-npm install --save-dev sass-graph
-```
-
-## Usage
-
-Usage as a Node library:
-
-```js
-var sassGraph = require('./sass-graph');
-```
-
-Usage as a command line tool:
-
-The command line tool will parse a graph and then either display ancestors, descendents or both.
-
-```
-$ ./bin/sassgraph --help
-Usage: bin/sassgraph <command> [options] <dir> [file]
-
-Commands:
-  ancestors    Output the ancestors
-  descendents  Output the descendents
-
-Options:
-  -I, --load-path   Add directories to the sass load path
-  -e, --extensions  File extensions to include in the graph
-  -j, --json        Output the index in json
-  -h, --help        Show help
-  -v, --version     Show version number
-
-Examples:
-  ./bin/sassgraph descendents test/fixtures test/fixtures/a.scss
-  /path/to/test/fixtures/b.scss
-  /path/to/test/fixtures/_c.scss
-```
-
-## API
-
-#### parseDir
-
-Parses a directory and builds a dependency graph of all requested file extensions.
-
-#### parseFile
-
-Parses a file and builds its dependency graph.
-
-## Options
-
-#### loadPaths
-
-Type: `Array`
-Default: `[process.cwd]`
-
-Directories to use when resolved `@import` directives.
-
-#### extensions
-
-Type: `Array`
-Default: `['scss', 'css', 'sass']`
-
-File types to be parsed.

-
-## Example
-
-```js
-var sassGraph = require('./sass-graph');
-console.log(sassGraph.parseDir('test/fixtures'));
-
-//{ index: {,
-//    '/path/to/test/fixtures/a.scss': {
-//        imports: ['b.scss'],
-//        importedBy: [],
-//    },
-//    '/path/to/test/fixtures/b.scss': {
-//        imports: ['_c.scss'],
-//        importedBy: ['a.scss'],
-//    },
-//    '/path/to/test/fixtures/_c.scss': {
-//        imports: [],
-//        importedBy: ['b/scss'],
-//    },
-//}}
-```

+
+      "Derivative Works" shall mean any work, whether in Source or Object
+      form, that is based on (or derived from) the Work and for which the
+      editorial revisions, annotations, elaborations, or other modifications
+      represent, as a whole, an original work of authorship. For the purposes
+      of this License, Derivative Works shall not include works that remain

+
+      (d) If the Work includes a "NOTICE" text file as part of its
+          distribution, then any Derivative Works that You distribute must
+          include a readable copy of the attribution notices contained
+          within such NOTICE file, excluding those notices that do not
+          pertain to any part of the Derivative Works, in at least one
+          of the following places: within a NOTICE text file distributed
+          as part of the Derivative Works; within the Source form or
+          documentation, if provided along with the Derivative Works; or,
+          within a display generated by the Derivative Works, if and
+          wherever such third-party notices normally appear. The contents
+          of the NOTICE file are for informational purposes only and
+          do not modify the License. You may add Your own attribution
+          notices within Derivative Works that You distribute, alongside
+          or as an addendum to the NOTICE text from the Work, provided
+          that such additional attribution notices cannot be construed
+          as modifying the License.
+
+      You may add Your own copyright statement to Your modifications and
+      may provide additional or different license terms and conditions
+      for use, reproduction, or distribution of Your modifications, or
+      for any such Derivative Works as a whole, provided Your use,
+      reproduction, and distribution of the Work otherwise complies with
+      the conditions stated in this License.
+
+   5. Submission of Contributions. Unless You explicitly state otherwise,
+      any Contribution intentionally submitted for inclusion in the Work
+      by You to the Licensor shall be under the terms and conditions of
+      this License, without any additional terms or conditions.
+      Notwithstanding the above, nothing herein shall supersede or modify
+      the terms of any separate license agreement you may have executed
+      with Licensor regarding such Contributions.
+
+   6. Trademarks. This License does not grant permission to use the trade
+      names, trademarks, service marks, or product names of the Licensor,
+      except as required for reasonable and customary use in describing the
+      origin of the Work and reproducing the content of the NOTICE file.
+
+   7. Disclaimer of Warranty. Unless required by applicable law or
+      agreed to in writing, Licensor provides the Work (and each
+      Contributor provides its Contributions) on an "AS IS" BASIS,
+      WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or
+      implied, including, without limitation, any warranties or conditions
+      of TITLE, NON-INFRINGEMENT, MERCHANTABILITY, or FITNESS FOR A
+      PARTICULAR PURPOSE. You are solely responsible for determining the
+      appropriateness of using or redistributing the Work and assume any
+      risks associated with Your exercise of permissions under this License.
+
+   8. Limitation of Liability. In no event and under no legal theory,
+      whether in tort (including negligence), contract, or otherwise,
+      unless required by applicable law (such as deliberate and grossly
+      negligent acts) or agreed to in writing, shall any Contributor be
+      liable to You for damages, including any direct, indirect, special,
+      incidental, or consequential damages of any character arising as a
+      result of this License or out of the use or inability to use the
+      Work (including but not limited to damages for loss of goodwill,
+      work stoppage, computer failure or malfunction, or any and all
+      other commercial damages or losses), even if such Contributor
+      has been advised of the possibility of such damages.
+
+   9. Accepting Warranty or Additional Liability. While redistributing
+      the Work or Derivative Works thereof, You may choose to offer,
+      and charge a fee for, acceptance of support, warranty, indemnity,
+      or other liability obligations and/or rights consistent with this
+      License. However, in accepting such obligations, You may act only
+      on Your own behalf and on Your sole responsibility, not on behalf
+      of any other Contributor, and only if You agree to indemnify,
+      defend, and hold each Contributor harmless for any liability
+      incurred by, or claims asserted against, such Contributor by reason
+      of your accepting any such warranty or additional liability.
+

+
+   TERMS AND CONDITIONS FOR USE, REPRODUCTION, AND DISTRIBUTION
+
+   1. Definitions.
+
+      "License" shall mean the terms and conditions for use, reproduction,
+      and distribution as defined by Sections 1 through 9 of this document.
+
+      "Licensor" shall mean the copyright owner or entity authorized by
+      the copyright owner that is granting the License.
+
+      "Legal Entity" shall mean the union of the acting entity and all
+      other entities that control, are controlled by, or are under common
+      control with that entity. For the purposes of this definition,
+      "control" means (i) the power, direct or indirect, to cause the
+      direction or management of such entity, whether by contract or
+      otherwise, or (ii) ownership of fifty percent (50%) or more of the
+      outstanding shares, or (iii) beneficial ownership of such entity.
+
+      "You" (or "Your") shall mean an individual or Legal Entity
+      exercising permissions granted by this License.
+
+      "Source" form shall mean the preferred form for making modifications,
+      including but not limited to software source code, documentation
+      source, and configuration files.
+
+      "Object" form shall mean any form resulting from mechanical
+      transformation or translation of a Source form, including but
+      not limited to compiled object code, generated documentation,
+      and conversions to other media types.
+
+      "Work" shall mean the work of authorship, whether in Source or
+      Object form, made available under the License, as indicated by a
+      copyright notice that is included in or attached to the work
+      (an example is provided in the Appendix below).
+
+      "Derivative Works" shall mean any work, whether in Source or Object
+      form, that is based on (or derived from) the Work and for which the
+      editorial revisions, annotations, elaborations, or other modifications
+      represent, as a whole, an original work of authorship. For the purposes
+      of this License, Derivative Works shall not include works that remain
+      separable from, or merely link (or bind by name) to the interfaces of,
+      the Work and Derivative Works thereof.
+
+      "Contribution" shall mean any work of authorship, including
+      the original version of the Work and any modifications or additions
+      to that Work or Derivative Works thereof, that is intentionally
+      submitted to Licensor for inclusion in the Work by the copyright owner
+      or by an individual or Legal Entity authorized to submit on behalf of
+      the copyright owner. For the purposes of this definition, "submitted"
+      means any form of electronic, verbal, or written communication sent
+      to the Licensor or its representatives, including but not limited to
+      communication on electronic mailing lists, source code control systems,
+      and issue tracking systems that are managed by, or on behalf of, the
+      Licensor for the purpose of discussing and improving the Work, but
+      excluding communication that is conspicuously marked or otherwise
+      designated in writing by the copyright owner as "Not a Contribution."
+
+      "Contributor" shall mean Licensor and any individual or Legal Entity
+      on behalf of whom a Contribution has been received by Licensor and
+      subsequently incorporated within the Work.
+
+   2. Grant of Copyright License. Subject to the terms and conditions of
+      this License, each Contributor hereby grants to You a perpetual,
+      worldwide, non-exclusive, no-charge, royalty-free, irrevocable
+      copyright license to reproduce, prepare Derivative Works of,
+      publicly display, publicly perform, sublicense, and distribute the
+      Work and such Derivative Works in Source or Object form.
+
+   3. Grant of Patent License. Subject to the terms and conditions of
+      this License, each Contributor hereby grants to You a perpetual,
+      worldwide, non-exclusive, no-charge, royalty-free, irrevocable
+      (except as stated in this section) patent license to make, have made,
+      use, offer to sell, sell, import, and otherwise transfer the Work,
+      where such license applies only to those patent claims licensable
+      by such Contributor that are necessarily infringed by their
+      Contribution(s) alone or by combination of their Contribution(s)
+      with the Work to which such Contribution(s) was submitted. If You
+      institute patent litigation against any entity (including a
+      cross-claim or counterclaim in a lawsuit) alleging that the Work
+      or a Contribution incorporated within the Work constitutes direct
+      or contributory patent infringement, then any patent licenses
+      granted to You under this License for that Work shall terminate
+      as of the date such litigation is filed.
+
+   4. Redistribution. You may reproduce and distribute copies of the
+      Work or Derivative Works thereof in any medium, with or without
+      modifications, and in Source or Object form, provided that You
+      meet the following conditions:
+
+      (a) You must give any other recipients of the Work or
+          Derivative Works a copy of this License; and
+
+      (b) You must cause any modified files to carry prominent notices
+          stating that You changed the files; and
+
+      (c) You must retain, in the Source form of any Derivative Works
+          that You distribute, all copyright, patent, trademark, and
+          attribution notices from the Source form of the Work,
+          excluding those notices that do not pertain to any part of
+          the Derivative Works; and
+
+      (d) If the Work includes a "NOTICE" text file as part of its
+          distribution, then any Derivative Works that You distribute must
+          include a readable copy of the attribution notices contained
+          within such NOTICE file, excluding those notices that do not
+          pertain to any part of the Derivative Works, in at least one
+          of the following places: within a NOTICE text file distributed
+          as part of the Derivative Works; within the Source form or
+          documentation, if provided along with the Derivative Works; or,
+          within a display generated by the Derivative Works, if and
+          wherever such third-party notices normally appear. The contents
+          of the NOTICE file are for informational purposes only and
+          do not modify the License. You may add Your own attribution
+          notices within Derivative Works that You distribute, alongside
+          or as an addendum to the NOTICE text from the Work, provided
+          that such additional attribution notices cannot be construed
+          as modifying the License.
+
+      You may add Your own copyright statement to Your modifications and
+      may provide additional or different license terms and conditions
+      for use, reproduction, or distribution of Your modifications, or
+      for any such Derivative Works as a whole, provided Your use,
+      reproduction, and distribution of the Work otherwise complies with
+      the conditions stated in this License.
+
+   5. Submission of Contributions. Unless You explicitly state otherwise,
+      any Contribution intentionally submitted for inclusion in the Work
+      by You to the Licensor shall be under the terms and conditions of
+      this License, without any additional terms or conditions.
+      Notwithstanding the above, nothing herein shall supersede or modify
+      the terms of any separate license agreement you may have executed
+      with Licensor regarding such Contributions.
+
+   6. Trademarks. This License does not grant permission to use the trade
+      names, trademarks, service marks, or product names of the Licensor,
+      except as required for reasonable and customary use in describing the
+      origin of the Work and reproducing the content of the NOTICE file.
+
+   7. Disclaimer of Warranty. Unless required by applicable law or
+      agreed to in writing, Licensor provides the Work (and each
+      Contributor provides its Contributions) on an "AS IS" BASIS,
+      WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or
+      implied, including, without limitation, any warranties or conditions
+      of TITLE, NON-INFRINGEMENT, MERCHANTABILITY, or FITNESS FOR A
+      PARTICULAR PURPOSE. You are solely responsible for determining the
+      appropriateness of using or redistributing the Work and assume any
+      risks associated with Your exercise of permissions under this License.
+
+   8. Limitation of Liability. In no event and under no legal theory,
+      whether in tort (including negligence), contract, or otherwise,
+      unless required by applicable law (such as deliberate and grossly
+      negligent acts) or agreed to in writing, shall any Contributor be
+      liable to You for damages, including any direct, indirect, special,
+      incidental, or consequential damages of any character arising as a
+      result of this License or out of the use or inability to use the
+      Work (including but not limited to damages for loss of goodwill,
+      work stoppage, computer failure or malfunction, or any and all
+      other commercial damages or losses), even if such Contributor
+      has been advised of the possibility of such damages.
+
+   9. Accepting Warranty or Additional Liability. While redistributing
+      the Work or Derivative Works thereof, You may choose to offer,
+      and charge a fee for, acceptance of support, warranty, indemnity,
+      or other liability obligations and/or rights consistent with this
+      License. However, in accepting such obligations, You may act only
+      on Your own behalf and on Your sole responsibility, not on behalf
+      of any other Contributor, and only if You agree to indemnify,
+      defend, and hold each Contributor harmless for any liability
+      incurred by, or claims asserted against, such Contributor by reason
+      of your accepting any such warranty or additional liability.
+
+   END OF TERMS AND CONDITIONS
+
+   APPENDIX: How to apply the Apache License to your work.

+[sass]: https://sass-lang.com/
+
+This package is a distribution of [Dart Sass][], compiled to pure JavaScript
+with no native code or external dependencies. It provides a command-line `sass`
+executable and a Node.js API.
+
+[Dart Sass]: https://github.com/sass/dart-sass
+
+* [Usage](#usage)
+* [See Also](#see-also)
+* [Behavioral Differences from Ruby Sass](#behavioral-differences-from-ruby-sass)
+
+## Usage
+
+You can install Sass globally using `npm install -g sass` which will provide
+access to the `sass` executable. You can also add it to your project using
+`npm install --save-dev sass`. This provides the executable as well as a
+library:
+
+[npm]: https://www.npmjs.com/package/sass
+
+```js
+const sass = require('sass');
+
+const result = sass.compile(scssFilename);
+
+// OR
+
+// Note that `compileAsync()` is substantially slower than `compile()`.
+const result = await sass.compileAsync(scssFilename);
+```
+
+See [the Sass website][js api] for full API documentation.
+
+[js api]: https://sass-lang.com/documentation/js-api
+
+### Legacy API
+
+Dart Sass also supports an older JavaScript API that's fully compatible with
+[Node Sass] (with a few exceptions listed below), with support for both the
+[`render()`] and [`renderSync()`] functions. This API is considered deprecated
+and will be removed in Dart Sass 2.0.0, so it should be avoided in new projects.
+
+[Node Sass]: https://github.com/sass/node-sass
+[`render()`]: https://sass-lang.com/documentation/js-api/modules#render
+[`renderSync()`]: https://sass-lang.com/documentation/js-api/modules#renderSync
+
+Sass's support for the legacy JavaScript API has the following limitations:
+
+* Only the `"expanded"` and `"compressed"` values of [`outputStyle`] are
+  supported.
+
+* Dart Sass doesn't support the [`precision`] option. Dart Sass defaults to a
+  sufficiently high precision for all existing browsers, and making this
+  customizable would make the code substantially less efficient.
+
+* Dart Sass doesn't support the [`sourceComments`] option. Source maps are the
+  recommended way of locating the origin of generated selectors.
+
+[`outputStyle`]: https://sass-lang.com/documentation/js-api/interfaces/LegacySharedOptions#outputStyle
+[`precision`]: https://github.com/sass/node-sass#precision
+[`sourceComments`]: https://github.com/sass/node-sass#sourcecomments
+
+## See Also
+
+* [Dart Sass][], from which this package is compiled, can be used either as a
+  stand-alone executable or as a Dart library. Running Dart Sass on the Dart VM
+  is substantially faster than running the pure JavaScript version, so this may
+  be appropriate for performance-sensitive applications. The Dart API is also
+  (currently) more user-friendly than the JavaScript API. See
+  [the Dart Sass README][Using Dart Sass] for details on how to use it.
+
+* [Node Sass][], which is a wrapper around [LibSass][], the C++ implementation
+  of Sass. Node Sass supports the same API as this package and is also faster
+  (although it's usually a little slower than Dart Sass). However, it requires a
+  native library which may be difficult to install, and it's generally slower to
+  add features and fix bugs.
+

+
+## Behavioral Differences from Ruby Sass
+
+There are a few intentional behavioral differences between Dart Sass and Ruby
+Sass. These are generally places where Ruby Sass has an undesired behavior, and
+it's substantially easier to implement the correct behavior than it would be to
+implement compatible behavior. These should all have tracking bugs against Ruby
+Sass to update the reference behavior.
+
+1. `@extend` only accepts simple selectors, as does the second argument of
+   `selector-extend()`. See [issue 1599][].
+
+2. Subject selectors are not supported. See [issue 1126][].
+
+3. Pseudo selector arguments are parsed as `<declaration-value>`s rather than
+   having a more limited custom parsing. See [issue 2120][].
+
+4. The numeric precision is set to 10. See [issue 1122][].
+
+5. The indented syntax parser is more flexible: it doesn't require consistent
+   indentation across the whole document. See [issue 2176][].
+
+6. Colors do not support channel-by-channel arithmetic. See [issue 2144][].
+
+7. Unitless numbers aren't `==` to unit numbers with the same value. In
+   addition, map keys follow the same logic as `==`-equality. See
+   [issue 1496][].
+
+8. `rgba()` and `hsla()` alpha values with percentage units are interpreted as
+   percentages. Other units are forbidden. See [issue 1525][].
+
+9. Too many variable arguments passed to a function is an error. See
+   [issue 1408][].
+
+10. Allow `@extend` to reach outside a media query if there's an identical
+    `@extend` defined outside that query. This isn't tracked explicitly, because
+    it'll be irrelevant when [issue 1050][] is fixed.
+
+11. Some selector pseudos containing placeholder selectors will be compiled
+    where they wouldn't be in Ruby Sass. This better matches the semantics of
+    the selectors in question, and is more efficient. See [issue 2228][].
+
+12. The old-style `:property value` syntax is not supported in the indented
+    syntax. See [issue 2245][].
+
+13. The reference combinator is not supported. See [issue 303][].
+
+14. Universal selector unification is symmetrical. See [issue 2247][].
+
+15. `@extend` doesn't produce an error if it matches but fails to unify. See
+    [issue 2250][].
+
+16. Dart Sass currently only supports UTF-8 documents. We'd like to support
+    more, but Dart currently doesn't support them. See [dart-lang/sdk#11744][],
+    for example.

+anymatch [![Build Status](https://travis-ci.org/micromatch/anymatch.svg?branch=master)](https://travis-ci.org/micromatch/anymatch) [![Coverage Status](https://img.shields.io/coveralls/micromatch/anymatch.svg?branch=master)](https://coveralls.io/r/micromatch/anymatch?branch=master)
+======
+Javascript module to match a string against a regular expression, glob, string,
+or function that takes the string as an argument and returns a truthy or falsy
+value. The matcher can also be an array of any or all of these. Useful for
+allowing a very flexible user-defined config to define things like file paths.
+
+__Note: This module has Bash-parity, please be aware that Windows-style backslashes are not supported as separators. See https://github.com/micromatch/micromatch#backslashes for more information.__
+
+
+Usage
+-----
+```sh
+npm install anymatch
+```
+
+#### anymatch(matchers, testString, [returnIndex], [options])
+* __matchers__: (_Array|String|RegExp|Function_)
+String to be directly matched, string with glob patterns, regular expression
+test, function that takes the testString as an argument and returns a truthy
+value if it should be matched, or an array of any number and mix of these types.
+* __testString__: (_String|Array_) The string to test against the matchers. If
+passed as an array, the first element of the array will be used as the
+`testString` for non-function matchers, while the entire array will be applied
+as the arguments for function matchers.
+* __options__: (_Object_ [optional]_) Any of the [picomatch](https://github.com/micromatch/picomatch#options) options.
+    * __returnIndex__: (_Boolean [optional]_) If true, return the array index of
+the first matcher that that testString matched, or -1 if no match, instead of a
+boolean result.
+
+```js
+const anymatch = require('anymatch');
+
+const matchers = [ 'path/to/file.js', 'path/anyjs/**/*.js', /foo.js$/, string => string.includes('bar') && string.length > 10 ] ;
+
+anymatch(matchers, 'path/to/file.js'); // true
+anymatch(matchers, 'path/anyjs/baz.js'); // true
+anymatch(matchers, 'path/to/foo.js'); // true
+anymatch(matchers, 'path/to/bar.js'); // true
+anymatch(matchers, 'bar.js'); // false
+
+// returnIndex = true
+anymatch(matchers, 'foo.js', {returnIndex: true}); // 2
+anymatch(matchers, 'path/anyjs/foo.js', {returnIndex: true}); // 1
+
+// any picomatc
+
+// using globs to match directories and their children
+anymatch('node_modules', 'node_modules'); // true
+anymatch('node_modules', 'node_modules/somelib/index.js'); // false
+anymatch('node_modules/**', 'node_modules/somelib/index.js'); // true
+anymatch('node_modules/**', '/absolute/path/to/node_modules/somelib/index.js'); // false
+anymatch('**/node_modules/**', '/absolute/path/to/node_modules/somelib/index.js'); // true
+
+const matcher = anymatch(matchers);
+['foo.js', 'bar.js'].filter(matcher);  // [ 'foo.js' ]
+anymatch master* ❯
+
+```
+
+#### anymatch(matchers)
+You can also pass in only your matcher(s) to get a curried function that has
+already been bound to the provided matching criteria. This can be used as an
+`Array#filter` callback.
+
+```js
+var matcher = anymatch(matchers);
+
+matcher('path/to/file.js'); // true
+matcher('path/anyjs/baz.js', true); // 1
+
+['foo.js', 'bar.js'].filter(matcher); // ['foo.js']
+```
+
+Changelog
+----------
+[See release notes page on GitHub](https://github.com/micromatch/anymatch/releases)
+
+- **v3.0:** Removed `startIndex` and `endIndex` arguments. Node 8.x-only.
+- **v2.0:** [micromatch](https://github.com/jonschlinkert/micromatch) moves away from minimatch-parity and inline with Bash. This includes handling backslashes differently (see https://github.com/micromatch/micromatch#backslashes for more information).
+- **v1.2:** anymatch uses [micromatch](https://github.com/jonschlinkert/micromatch)
+for glob pattern matching. Issues with glob pattern matching should be
+reported directly to the [micromatch issue tracker](https://github.com/jonschlinkert/micromatch/issues).

+
+> Bash-like brace expansion, implemented in JavaScript. Safer than other brace expansion libs, with complete support for the Bash 4.3 braces specification, without sacrificing speed.
+
+Please consider following this project's author, [Jon Schlinkert](https://github.com/jonschlinkert), and consider starring the project to show your :heart: and support.
+
+## Install
+
+Install with [npm](https://www.npmjs.com/):
+
+```sh
+$ npm install --save braces
+```
+
+## v3.0.0 Released!!
+
+See the [changelog](CHANGELOG.md) for details.
+
+## Why use braces?
+
+Brace patterns make globs more powerful by adding the ability to match specific ranges and sequences of characters.
+
+* **Accurate** - complete support for the [Bash 4.3 Brace Expansion](www.gnu.org/software/bash/) specification (passes all of the Bash braces tests)
+* **[fast and performant](#benchmarks)** - Starts fast, runs fast and [scales well](#performance) as patterns increase in complexity.
+* **Organized code base** - The parser and compiler are easy to maintain and update when edge cases crop up.
+* **Well-tested** - Thousands of test assertions, and passes all of the Bash, minimatch, and [brace-expansion](https://github.com/juliangruber/brace-expansion) unit tests (as of the date this was written).
+* **Safer** - You shouldn't have to worry about users defining aggressive or malicious brace patterns that can break your application. Braces takes measures to prevent malicious regex that can be used for DDoS attacks (see [catastrophic backtracking](https://www.regular-expressions.info/catastrophic.html)).
+* [Supports lists](#lists) - (aka "sets") `a/{b,c}/d` => `['a/b/d', 'a/c/d']`
+* [Supports sequences](#sequences) - (aka "ranges") `{01..03}` => `['01', '02', '03']`
+* [Supports steps](#steps) - (aka "increments") `{2..10..2}` => `['2', '4', '6', '8', '10']`
+* [Supports escaping](#escaping) - To prevent evaluation of special characters.
+
+## Usage
+
+The main export is a function that takes one or more brace `patterns` and `options`.
+
+```js
+const braces = require('braces');
+// braces(patterns[, options]);
+
+console.log(braces(['{01..05}', '{a..e}']));
+//=> ['(0[1-5])', '([a-e])']
+
+console.log(braces(['{01..05}', '{a..e}'], { expand: true }));
+//=> ['01', '02', '03', '04', '05', 'a', 'b', 'c', 'd', 'e']
+```
+
+### Brace Expansion vs. Compilation
+
+By default, brace patterns are compiled into strings that are optimized for creating regular expressions and matching.
+
+**Compiled**
+
+```js
+console.log(braces('a/{x,y,z}/b')); 
+//=> ['a/(x|y|z)/b']
+console.log(braces(['a/{01..20}/b', 'a/{1..5}/b'])); 
+//=> [ 'a/(0[1-9]|1[0-9]|20)/b', 'a/([1-5])/b' ]
+```
+
+**Expanded**
+
+Enable brace expansion by setting the `expand` option to true, or by using [braces.expand()](#expand) (returns an array similar to what you'd expect from Bash, or `echo {1..5}`, or [minimatch](https://github.com/isaacs/minimatch)):
+
+```js
+console.log(braces('a/{x,y,z}/b', { expand: true }));
+//=> ['a/x/b', 'a/y/b', 'a/z/b']
+
+console.log(braces.expand('{01..10}'));
+//=> ['01','02','03','04','05','06','07','08','09','10']
+```
+
+### Lists
+
+Expand lists (like Bash "sets"):
+
+```js
+console.log(braces('a/{foo,bar,baz}/*.js'));
+//=> ['a/(foo|bar|baz)/*.js']
+
+console.log(braces.expand('a/{foo,bar,baz}/*.js'));
+//=> ['a/foo/*.js', 'a/bar/*.js', 'a/baz/*.js']
+```
+
+### Sequences
+
+Expand ranges of characters (like Bash "sequences"):
+
+```js
+console.log(braces.expand('{1..3}'));                // ['1', '2', '3']
+console.log(braces.expand('a/{1..3}/b'));            // ['a/1/b', 'a/2/b', 'a/3/b']
+console.log(braces('{a..c}', { expand: true }));     // ['a', 'b', 'c']
+console.log(braces('foo/{a..c}', { expand: true })); // ['foo/a', 'foo/b', 'foo/c']
+
+// supports zero-padded ranges
+console.log(braces('a/{01..03}/b'));   //=> ['a/(0[1-3])/b']
+console.log(braces('a/{001..300}/b')); //=> ['a/(0{2}[1-9]|0[1-9][0-9]|[12][0-9]{2}|300)/b']
+```
+
+See [fill-range](https://github.com/jonschlinkert/fill-range) for all available range-expansion options.
+
+### Steppped ranges
+
+Steps, or increments, may be used with ranges:
+
+```js
+console.log(braces.expand('{2..10..2}'));
+//=> ['2', '4', '6', '8', '10']
+
+console.log(braces('{2..10..2}'));
+//=> ['(2|4|6|8|10)']
+```
+
+When the [.optimize](#optimize) method is used, or [options.optimize](#optionsoptimize) is set to true, sequences are passed to [to-regex-range](https://github.com/jonschlinkert/to-regex-range) for expansion.
+
+### Nesting
+
+Brace patterns may be nested. The results of each expanded string are not sorted, and left to right order is preserved.
+
+**"Expanded" braces**
+
+```js
+console.log(braces.expand('a{b,c,/{x,y}}/e'));
+//=> ['ab/e', 'ac/e', 'a/x/e', 'a/y/e']
+
+console.log(braces.expand('a/{x,{1..5},y}/c'));
+//=> ['a/x/c', 'a/1/c', 'a/2/c', 'a/3/c', 'a/4/c', 'a/5/c', 'a/y/c']
+```
+
+**"Optimized" braces**
+
+```js
+console.log(braces('a{b,c,/{x,y}}/e'));
+//=> ['a(b|c|/(x|y))/e']
+
+console.log(braces('a/{x,{1..5},y}/c'));
+//=> ['a/(x|([1-5])|y)/c']
+```
+
+### Escaping
+
+**Escaping braces**
+
+A brace pattern will not be expanded or evaluted if _either the opening or closing brace is escaped_:
+
+```js
+console.log(braces.expand('a\\{d,c,b}e'));
+//=> ['a{d,c,b}e']
+
+console.log(braces.expand('a{d,c,b\\}e'));
+//=> ['a{d,c,b}e']
+```
+
+**Escaping commas**
+
+Commas inside braces may also be escaped:
+
+```js
+console.log(braces.expand('a{b\\,c}d'));
+//=> ['a{b,c}d']
+
+console.log(braces.expand('a{d\\,c,b}e'));
+//=> ['ad,ce', 'abe']
+```
+
+**Single items**
+
+Following bash conventions, a brace pattern is also not expanded when it contains a single character:
+
+```js
+console.log(braces.expand('a{b}c'));
+//=> ['a{b}c']
+```
+
+## Options
+
+### options.maxLength
+
+**Type**: `Number`
+
+**Default**: `65,536`
+
+**Description**: Limit the length of the input string. Useful when the input string is generated or your application allows users to pass a string, et cetera.
+
+```js
+console.log(braces('a/{b,c}/d', { maxLength: 3 }));  //=> throws an error
+```
+
+### options.expand
+
+**Type**: `Boolean`
+
+**Default**: `undefined`
+
+**Description**: Generate an "expanded" brace pattern (alternatively you can use the `braces.expand()` method, which does the same thing).
+
+```js
+console.log(braces('a/{b,c}/d', { expand: true }));
+//=> [ 'a/b/d', 'a/c/d' ]
+```
+
+### options.nodupes
+
+**Type**: `Boolean`
+
+**Default**: `undefined`
+
+**Description**: Remove duplicates from the returned array.
+
+### options.rangeLimit
+
+**Type**: `Number`
+
+**Default**: `1000`
+
+**Description**: To prevent malicious patterns from being passed by users, an error is thrown when `braces.expand()` is used or `options.expand` is true and the generated range will exceed the `rangeLimit`.
+
+You can customize `options.rangeLimit` or set it to `Inifinity` to disable this altogether.
+
+**Examples**
+
+```js
+// pattern exceeds the "rangeLimit", so it's optimized automatically
+console.log(braces.expand('{1..1000}'));
+//=> ['([1-9]|[1-9][0-9]{1,2}|1000)']
+
+// pattern does not exceed "rangeLimit", so it's NOT optimized
+console.log(braces.expand('{1..100}'));
+//=> ['1', '2', '3', '4', '5', '6', '7', '8', '9', '10', '11', '12', '13', '14', '15', '16', '17', '18', '19', '20', '21', '22', '23', '24', '25', '26', '27', '28', '29', '30', '31', '32', '33', '34', '35', '36', '37', '38', '39', '40', '41', '42', '43', '44', '45', '46', '47', '48', '49', '50', '51', '52', '53', '54', '55', '56', '57', '58', '59', '60', '61', '62', '63', '64', '65', '66', '67', '68', '69', '70', '71', '72', '73', '74', '75', '76', '77', '78', '79', '80', '81', '82', '83', '84', '85', '86', '87', '88', '89', '90', '91', '92', '93', '94', '95', '96', '97', '98', '99', '100']
+```
+
+### options.transform
+
+**Type**: `Function`
+
+**Default**: `undefined`
+
+**Description**: Customize range expansion.
+
+**Example: Transforming non-numeric values**
+
+```js
+const alpha = braces.expand('x/{a..e}/y', {
+  transform(value, index) {
+    // When non-numeric values are passed, "value" is a character code.
+    return 'foo/' + String.fromCharCode(value) + '-' + index;
+  }
+});
+console.log(alpha);
+//=> [ 'x/foo/a-0/y', 'x/foo/b-1/y', 'x/foo/c-2/y', 'x/foo/d-3/y', 'x/foo/e-4/y' ]
+```
+
+**Example: Transforming numeric values**
+
+```js
+const numeric = braces.expand('{1..5}', {
+  transform(value) {
+    // when numeric values are passed, "value" is a number
+    return 'foo/' + value * 2;
+  }
+});
+console.log(numeric); 
+//=> [ 'foo/2', 'foo/4', 'foo/6', 'foo/8', 'foo/10' ]
+```
+
+### options.quantifiers
+
+**Type**: `Boolean`
+
+**Default**: `undefined`
+
+**Description**: In regular expressions, quanitifiers can be used to specify how many times a token can be repeated. For example, `a{1,3}` will match the letter `a` one to three times.
+
+Unfortunately, regex quantifiers happen to share the same syntax as [Bash lists](#lists)
+
+The `quantifiers` option tells braces to detect when [regex quantifiers](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/RegExp#quantifiers) are defined in the given pattern, and not to try to expand them as lists.
+
+**Examples**
+
+```js
+const braces = require('braces');
+console.log(braces('a/b{1,3}/{x,y,z}'));
+//=> [ 'a/b(1|3)/(x|y|z)' ]
+console.log(braces('a/b{1,3}/{x,y,z}', {quantifiers: true}));
+//=> [ 'a/b{1,3}/(x|y|z)' ]
+console.log(braces('a/b{1,3}/{x,y,z}', {quantifiers: true, expand: true}));
+//=> [ 'a/b{1,3}/x', 'a/b{1,3}/y', 'a/b{1,3}/z' ]
+```
+
+### options.unescape
+
+**Type**: `Boolean`
+
+**Default**: `undefined`
+
+**Description**: Strip backslashes that were used for escaping from the result.
+
+## What is "brace expansion"?
+
+Brace expansion is a type of parameter expansion that was made popular by unix shells for generating lists of strings, as well as regex-like matching when used alongside wildcards (globs).
+
+In addition to "expansion", braces are also used for matching. In other words:
+
+* [brace expansion](#brace-expansion) is for generating new lists
+* [brace matching](#brace-matching) is for filtering existing lists
+
+<details>
+<summary><strong>More about brace expansion</strong> (click to expand)</summary>
+
+There are two main types of brace expansion:
+
+1. **lists**: which are defined using comma-separated values inside curly braces: `{a,b,c}`
+2. **sequences**: which are defined using a starting value and an ending value, separated by two dots: `a{1..3}b`. Optionally, a third argument may be passed to define a "step" or increment to use: `a{1..100..10}b`. These are also sometimes referred to as "ranges".
+
+Here are some example brace patterns to illustrate how they work:
+
+**Sets**
+
+```
+{a,b,c}       => a b c
+{a,b,c}{1,2}  => a1 a2 b1 b2 c1 c2
+```
+
+**Sequences**
+
+```
+{1..9}        => 1 2 3 4 5 6 7 8 9
+{4..-4}       => 4 3 2 1 0 -1 -2 -3 -4
+{1..20..3}    => 1 4 7 10 13 16 19
+{a..j}        => a b c d e f g h i j
+{j..a}        => j i h g f e d c b a
+{a..z..3}     => a d g j m p s v y
+```
+
+**Combination**
+
+Sets and sequences can be mixed together or used along with any other strings.
+
+```
+{a,b,c}{1..3}   => a1 a2 a3 b1 b2 b3 c1 c2 c3
+foo/{a,b,c}/bar => foo/a/bar foo/b/bar foo/c/bar
+```
+
+The fact that braces can be "expanded" from relatively simple patterns makes them ideal for quickly generating test fixtures, file paths, and similar use cases.
+
+## Brace matching
+
+In addition to _expansion_, brace patterns are also useful for performing regular-expression-like matching.
+
+For example, the pattern `foo/{1..3}/bar` would match any of following strings:
+
+```
+foo/1/bar
+foo/2/bar
+foo/3/bar
+```
+
+But not:
+
+```
+baz/1/qux
+baz/2/qux
+baz/3/qux
+```
+
+Braces can also be combined with [glob patterns](https://github.com/jonschlinkert/micromatch) to perform more advanced wildcard matching. For example, the pattern `*/{1..3}/*` would match any of following strings:
+
+```
+foo/1/bar
+foo/2/bar
+foo/3/bar
+baz/1/qux
+baz/2/qux
+baz/3/qux
+```
+
+## Brace matching pitfalls
+
+Although brace patterns offer a user-friendly way of matching ranges or sets of strings, there are also some major disadvantages and potential risks you should be aware of.
+
+### tldr
+
+**"brace bombs"**
+
+* brace expansion can eat up a huge amount of processing resources
+* as brace patterns increase _linearly in size_, the system resources required to expand the pattern increase exponentially
+* users can accidentally (or intentially) exhaust your system's resources resulting in the equivalent of a DoS attack (bonus: no programming knowledge is required!)
+
+For a more detailed explanation with examples, see the [geometric complexity](#geometric-complexity) section.
+
+### The solution
+
+Jump to the [performance section](#performance) to see how Braces solves this problem in comparison to other libraries.
+
+### Geometric complexity
+
+At minimum, brace patterns with sets limited to two elements have quadradic or `O(n^2)` complexity. But the complexity of the algorithm increases exponentially as the number of sets, _and elements per set_, increases, which is `O(n^c)`.
+
+For example, the following sets demonstrate quadratic (`O(n^2)`) complexity:
+
+```
+{1,2}{3,4}      => (2X2)    => 13 14 23 24
+{1,2}{3,4}{5,6} => (2X2X2)  => 135 136 145 146 235 236 245 246
+```
+
+But add an element to a set, and we get a n-fold Cartesian product with `O(n^c)` complexity:
+
+```
+{1,2,3}{4,5,6}{7,8,9} => (3X3X3) => 147 148 149 157 158 159 167 168 169 247 248 
+                                    249 257 258 259 267 268 269 347 348 349 357 
+                                    358 359 367 368 369
+```
+
+Now, imagine how this complexity grows given that each element is a n-tuple:
+
+```
+{1..100}{1..100}         => (100X100)     => 10,000 elements (38.4 kB)
+{1..100}{1..100}{1..100} => (100X100X100) => 1,000,000 elements (5.76 MB)
+```
+
+Although these examples are clearly contrived, they demonstrate how brace patterns can quickly grow out of control.

+## Performance
+
+Braces is not only screaming fast, it's also more accurate the other brace expansion libraries.
+
+### Better algorithms
+
+Fortunately there is a solution to the ["brace bomb" problem](#brace-matching-pitfalls): _don't expand brace patterns into an array when they're used for matching_.
+
+Instead, convert the pattern into an optimized regular expression. This is easier said than done, and braces is the only library that does this currently.
+
+**The proof is in the numbers**
+
+Minimatch gets exponentially slower as patterns increase in complexity, braces does not. The following results were generated using `braces()` and `minimatch.braceExpand()`, respectively.

+
+> Minimal and efficient cross-platform file watching library
+
+[![NPM](https://nodei.co/npm/chokidar.png)](https://www.npmjs.com/package/chokidar)
+
+## Why?
+
+Node.js `fs.watch`:
+
+* Doesn't report filenames on MacOS.
+* Doesn't report events at all when using editors like Sublime on MacOS.
+* Often reports events twice.
+* Emits most changes as `rename`.
+* Does not provide an easy way to recursively watch file trees.
+* Does not support recursive watching on Linux.
+
+Node.js `fs.watchFile`:
+
+* Almost as bad at event handling.
+* Also does not provide any recursive watching.
+* Results in high CPU utilization.
+
+Chokidar resolves these problems.
+
+Initially made for **[Brunch](https://brunch.io/)** (an ultra-swift web app build tool), it is now used in
+[Microsoft's Visual Studio Code](https://github.com/microsoft/vscode),
+[gulp](https://github.com/gulpjs/gulp/),
+[karma](https://karma-runner.github.io/),
+[PM2](https://github.com/Unitech/PM2),
+[browserify](http://browserify.org/),
+[webpack](https://webpack.github.io/),
+[BrowserSync](https://www.browsersync.io/),
+and [many others](https://www.npmjs.com/browse/depended/chokidar).
+It has proven itself in production environments.
+
+Version 3 is out! Check out our blog post about it: [Chokidar 3: How to save 32TB of traffic every week](https://paulmillr.com/posts/chokidar-3-save-32tb-of-traffic/)
+
+## How?
+
+Chokidar does still rely on the Node.js core `fs` module, but when using
+`fs.watch` and `fs.watchFile` for watching, it normalizes the events it
+receives, often checking for truth by getting file stats and/or dir contents.
+
+On MacOS, chokidar by default uses a native extension exposing the Darwin
+`FSEvents` API. This provides very efficient recursive watching compared with
+implementations like `kqueue` available on most \*nix platforms. Chokidar still
+does have to do some work to normalize the events received that way as well.
+
+On most other platforms, the `fs.watch`-based implementation is the default, which
+avoids polling and keeps CPU usage down. Be advised that chokidar will initiate
+watchers recursively for everything within scope of the paths that have been
+specified, so be judicious about not wasting system resources by watching much
+more than needed.
+
+## Getting started
+
+Install with npm:
+
+```sh
+npm install chokidar
+```
+
+Then `require` and use it in your code:
+
+```javascript
+const chokidar = require('chokidar');
+
+// One-liner for current directory
+chokidar.watch('.').on('all', (event, path) => {
+  console.log(event, path);
+});
+```
+
+## API
+
+```javascript
+// Example of a more typical implementation structure
+
+// Initialize watcher.
+const watcher = chokidar.watch('file, dir, glob, or array', {
+  ignored: /(^|[\/\\])\../, // ignore dotfiles
+  persistent: true
+});
+
+// Something to use when events are received.
+const log = console.log.bind(console);
+// Add event listeners.
+watcher
+  .on('add', path => log(`File ${path} has been added`))
+  .on('change', path => log(`File ${path} has been changed`))
+  .on('unlink', path => log(`File ${path} has been removed`));
+
+// More possible events.
+watcher
+  .on('addDir', path => log(`Directory ${path} has been added`))
+  .on('unlinkDir', path => log(`Directory ${path} has been removed`))
+  .on('error', error => log(`Watcher error: ${error}`))
+  .on('ready', () => log('Initial scan complete. Ready for changes'))
+  .on('raw', (event, path, details) => { // internal
+    log('Raw event info:', event, path, details);
+  });
+
+// 'add', 'addDir' and 'change' events also receive stat() results as second
+// argument when available: https://nodejs.org/api/fs.html#fs_class_fs_stats
+watcher.on('change', (path, stats) => {
+  if (stats) console.log(`File ${path} changed size to ${stats.size}`);
+});
+
+// Watch new files.
+watcher.add('new-file');
+watcher.add(['new-file-2', 'new-file-3', '**/other-file*']);
+
+// Get list of actual paths being watched on the filesystem
+var watchedPaths = watcher.getWatched();
+
+// Un-watch some files.
+await watcher.unwatch('new-file*');
+
+// Stop watching.
+// The method is async!
+watcher.close().then(() => console.log('closed'));
+
+// Full list of options. See below for descriptions.
+// Do not use this example!
+chokidar.watch('file', {
+  persistent: true,
+
+  ignored: '*.txt',
+  ignoreInitial: false,
+  followSymlinks: true,
+  cwd: '.',
+  disableGlobbing: false,
+
+  usePolling: false,
+  interval: 100,
+  binaryInterval: 300,
+  alwaysStat: false,
+  depth: 99,
+  awaitWriteFinish: {
+    stabilityThreshold: 2000,
+    pollInterval: 100
+  },
+
+  ignorePermissionErrors: false,
+  atomic: true // or a custom 'atomicity delay', in milliseconds (default 100)
+});
+
+```
+
+`chokidar.watch(paths, [options])`
+
+* `paths` (string or array of strings). Paths to files, dirs to be watched
+recursively, or glob patterns.
+    - Note: globs must not contain windows separators (`\`),
+    because that's how they work by the standard —
+    you'll need to replace them with forward slashes (`/`).
+    - Note 2: for additional glob documentation, check out low-level
+    library: [picomatch](https://github.com/micromatch/picomatch).
+* `options` (object) Options object as defined below:
+
+#### Persistence
+
+* `persistent` (default: `true`). Indicates whether the process
+should continue to run as long as files are being watched. If set to
+`false` when using `fsevents` to watch, no more events will be emitted
+after `ready`, even if the process continues to run.
+
+#### Path filtering
+
+* `ignored` ([anymatch](https://github.com/es128/anymatch)-compatible definition)
+Defines files/paths to be ignored. The whole relative or absolute path is
+tested, not just filename. If a function with two arguments is provided, it
+gets called twice per path - once with a single argument (the path), second
+time with two arguments (the path and the
+[`fs.Stats`](https://nodejs.org/api/fs.html#fs_class_fs_stats)
+object of that path).
+* `ignoreInitial` (default: `false`). If set to `false` then `add`/`addDir` events are also emitted for matching paths while
+instantiating the watching as chokidar discovers these file paths (before the `ready` event).
+* `followSymlinks` (default: `true`). When `false`, only the
+symlinks themselves will be watched for changes instead of following
+the link references and bubbling events through the link's path.
+* `cwd` (no default). The base directory from which watch `paths` are to be
+derived. Paths emitted with events will be relative to this.
+* `disableGlobbing` (default: `false`). If set to `true` then the strings passed to `.watch()` and `.add()` are treated as
+literal path names, even if they look like globs.
+
+#### Performance
+
+* `usePolling` (default: `false`).
+Whether to use fs.watchFile (backed by polling), or fs.watch. If polling
+leads to high CPU utilization, consider setting this to `false`. It is
+typically necessary to **set this to `true` to successfully watch files over
+a network**, and it may be necessary to successfully watch files in other
+non-standard situations. Setting to `true` explicitly on MacOS overrides the
+`useFsEvents` default. You may also set the CHOKIDAR_USEPOLLING env variable
+to true (1) or false (0) in order to override this option.
+* _Polling-specific settings_ (effective when `usePolling: true`)
+  * `interval` (default: `100`). Interval of file system polling, in milliseconds. You may also
+    set the CHOKIDAR_INTERVAL env variable to override this option.
+  * `binaryInterval` (default: `300`). Interval of file system
+  polling for binary files.
+  ([see list of binary extensions](https://github.com/sindresorhus/binary-extensions/blob/master/binary-extensions.json))
+* `useFsEvents` (default: `true` on MacOS). Whether to use the
+`fsevents` watching interface if available. When set to `true` explicitly
+and `fsevents` is available this supercedes the `usePolling` setting. When
+set to `false` on MacOS, `usePolling: true` becomes the default.
+* `alwaysStat` (default: `false`). If relying upon the
+[`fs.Stats`](https://nodejs.org/api/fs.html#fs_class_fs_stats)
+object that may get passed with `add`, `addDir`, and `change` events, set
+this to `true` to ensure it is provided even in cases where it wasn't
+already available from the underlying watch events.
+* `depth` (default: `undefined`). If set, limits how many levels of
+subdirectories will be traversed.
+* `awaitWriteFinish` (default: `false`).
+By default, the `add` event will fire when a file first appears on disk, before
+the entire file has been written. Furthermore, in some cases some `change`
+events will be emitted while the file is being written. In some cases,
+especially when watching for large files there will be a need to wait for the
+write operation to finish before responding to a file creation or modification.
+Setting `awaitWriteFinish` to `true` (or a truthy value) will poll file size,
+holding its `add` and `change` events until the size does not change for a
+configurable amount of time. The appropriate duration setting is heavily
+dependent on the OS and hardware. For accurate detection this parameter should
+be relatively high, making file watching much less responsive.
+Use with caution.
+  * *`options.awaitWriteFinish` can be set to an object in order to adjust
+  timing params:*
+  * `awaitWriteFinish.stabilityThreshold` (default: 2000). Amount of time in
+  milliseconds for a file size to remain constant before emitting its event.
+  * `awaitWriteFinish.pollInterval` (default: 100). File size polling interval, in milliseconds.
+
+#### Errors
+
+* `ignorePermissionErrors` (default: `false`). Indicates whether to watch files
+that don't have read permissions if possible. If watching fails due to `EPERM`
+or `EACCES` with this set to `true`, the errors will be suppressed silently.
+* `atomic` (default: `true` if `useFsEvents` and `usePolling` are `false`).
+Automatically filters out artifacts that occur when using editors that use
+"atomic writes" instead of writing directly to the source file. If a file is
+re-added within 100 ms of being deleted, Chokidar emits a `change` event
+rather than `unlink` then `add`. If the default of 100 ms does not work well
+for you, you can override it by setting `atomic` to a custom value, in
+milliseconds.
+
+### Methods & Events
+
+`chokidar.watch()` produces an instance of `FSWatcher`. Methods of `FSWatcher`:
+
+* `.add(path / paths)`: Add files, directories, or glob patterns for tracking.
+Takes an array of strings or just one string.
+* `.on(event, callback)`: Listen for an FS event.
+Available events: `add`, `addDir`, `change`, `unlink`, `unlinkDir`, `ready`,
+`raw`, `error`.
+Additionally `all` is available which gets emitted with the underlying event
+name and path for every event other than `ready`, `raw`, and `error`.  `raw` is internal, use it carefully.
+* `.unwatch(path / paths)`: Stop watching files, directories, or glob patterns.
+Takes an array of strings or just one string.
+* `.close()`: **async** Removes all listeners from watched files. Asynchronous, returns Promise. Use with `await` to ensure bugs don't happen.
+* `.getWatched()`: Returns an object representing all the paths on the file
+system being watched by this `FSWatcher` instance. The object's keys are all the
+directories (using absolute paths unless the `cwd` option was used), and the
+values are arrays of the names of the items contained in each directory.
+
+## CLI
+
+If you need a CLI interface for your file watching, check out
+[chokidar-cli](https://github.com/open-cli-tools/chokidar-cli), allowing you to
+execute a command on each change, or get a stdio stream of change events.
+
+## Install Troubleshooting
+
+* `npm WARN optional dep failed, continuing fsevents@n.n.n`
+  * This message is normal part of how `npm` handles optional dependencies and is
+    not indicative of a problem. Even if accompanied by other related error messages,
+    Chokidar should function properly.
+
+* `TypeError: fsevents is not a constructor`
+  * Update chokidar by doing `rm -rf node_modules package-lock.json yarn.lock && npm install`, or update your dependency that uses chokidar.
+
+* Chokidar is producing `ENOSP` error on Linux, like this:
+  * `bash: cannot set terminal process group (-1): Inappropriate ioctl for device bash: no job control in this shell`
+  `Error: watch /home/ ENOSPC`
+  * This means Chokidar ran out of file handles and you'll need to increase their count by executing the following command in Terminal:
+  `echo fs.inotify.max_user_watches=524288 | sudo tee -a /etc/sysctl.conf && sudo sysctl -p`

+
+> Fill in a range of numbers or letters, optionally passing an increment or `step` to use, or create a regex-compatible range with `options.toRegex`
+
+Please consider following this project's author, [Jon Schlinkert](https://github.com/jonschlinkert), and consider starring the project to show your :heart: and support.
+
+## Install
+
+Install with [npm](https://www.npmjs.com/):
+
+```sh
+$ npm install --save fill-range
+```
+
+## Usage
+
+Expands numbers and letters, optionally using a `step` as the last argument. _(Numbers may be defined as JavaScript numbers or strings)_.
+
+```js
+const fill = require('fill-range');
+// fill(from, to[, step, options]);
+
+console.log(fill('1', '10')); //=> ['1', '2', '3', '4', '5', '6', '7', '8', '9', '10']
+console.log(fill('1', '10', { toRegex: true })); //=> [1-9]|10
+```
+
+**Params**
+
+* `from`: **{String|Number}** the number or letter to start with
+* `to`: **{String|Number}** the number or letter to end with
+* `step`: **{String|Number|Object|Function}** Optionally pass a [step](#optionsstep) to use.
+* `options`: **{Object|Function}**: See all available [options](#options)
+
+## Examples
+
+By default, an array of values is returned.
+
+**Alphabetical ranges**
+
+```js
+console.log(fill('a', 'e')); //=> ['a', 'b', 'c', 'd', 'e']
+console.log(fill('A', 'E')); //=> [ 'A', 'B', 'C', 'D', 'E' ]
+```
+
+**Numerical ranges**
+
+Numbers can be defined as actual numbers or strings.
+
+```js
+console.log(fill(1, 5));     //=> [ 1, 2, 3, 4, 5 ]
+console.log(fill('1', '5')); //=> [ 1, 2, 3, 4, 5 ]
+```
+
+**Negative ranges**
+
+Numbers can be defined as actual numbers or strings.
+
+```js
+console.log(fill('-5', '-1')); //=> [ '-5', '-4', '-3', '-2', '-1' ]
+console.log(fill('-5', '5')); //=> [ '-5', '-4', '-3', '-2', '-1', '0', '1', '2', '3', '4', '5' ]
+```
+
+**Steps (increments)**
+
+```js
+// numerical ranges with increments
+console.log(fill('0', '25', 4)); //=> [ '0', '4', '8', '12', '16', '20', '24' ]
+console.log(fill('0', '25', 5)); //=> [ '0', '5', '10', '15', '20', '25' ]
+console.log(fill('0', '25', 6)); //=> [ '0', '6', '12', '18', '24' ]
+
+// alphabetical ranges with increments
+console.log(fill('a', 'z', 4)); //=> [ 'a', 'e', 'i', 'm', 'q', 'u', 'y' ]
+console.log(fill('a', 'z', 5)); //=> [ 'a', 'f', 'k', 'p', 'u', 'z' ]
+console.log(fill('a', 'z', 6)); //=> [ 'a', 'g', 'm', 's', 'y' ]
+```
+
+## Options
+
+### options.step
+
+**Type**: `number` (formatted as a string or number)
+
+**Default**: `undefined`
+
+**Description**: The increment to use for the range. Can be used with letters or numbers.
+
+**Example(s)**
+
+```js
+// numbers
+console.log(fill('1', '10', 2)); //=> [ '1', '3', '5', '7', '9' ]
+console.log(fill('1', '10', 3)); //=> [ '1', '4', '7', '10' ]
+console.log(fill('1', '10', 4)); //=> [ '1', '5', '9' ]
+
+// letters
+console.log(fill('a', 'z', 5)); //=> [ 'a', 'f', 'k', 'p', 'u', 'z' ]
+console.log(fill('a', 'z', 7)); //=> [ 'a', 'h', 'o', 'v' ]
+console.log(fill('a', 'z', 9)); //=> [ 'a', 'j', 's' ]
+```
+
+### options.strictRanges
+
+**Type**: `boolean`
+
+**Default**: `false`
+
+**Description**: By default, `null` is returned when an invalid range is passed. Enable this option to throw a `RangeError` on invalid ranges.
+
+**Example(s)**
+
+The following are all invalid:
+
+```js
+fill('1.1', '2');   // decimals not supported in ranges
+fill('a', '2');     // incompatible range values
+fill(1, 10, 'foo'); // invalid "step" argument
+```
+
+### options.stringify
+
+**Type**: `boolean`
+
+**Default**: `undefined`
+
+**Description**: Cast all returned values to strings. By default, integers are returned as numbers.
+
+**Example(s)**
+
+```js
+console.log(fill(1, 5));                    //=> [ 1, 2, 3, 4, 5 ]
+console.log(fill(1, 5, { stringify: true })); //=> [ '1', '2', '3', '4', '5' ]
+```
+
+### options.toRegex
+
+**Type**: `boolean`
+
+**Default**: `undefined`
+
+**Description**: Create a regex-compatible source string, instead of expanding values to an array.
+
+**Example(s)**
+
+```js
+// alphabetical range
+console.log(fill('a', 'e', { toRegex: true })); //=> '[a-e]'
+// alphabetical with step
+console.log(fill('a', 'z', 3, { toRegex: true })); //=> 'a|d|g|j|m|p|s|v|y'
+// numerical range
+console.log(fill('1', '100', { toRegex: true })); //=> '[1-9]|[1-9][0-9]|100'
+// numerical range with zero padding
+console.log(fill('000001', '100000', { toRegex: true }));
+//=> '0{5}[1-9]|0{4}[1-9][0-9]|0{3}[1-9][0-9]{2}|0{2}[1-9][0-9]{3}|0[1-9][0-9]{4}|100000'
+```
+
+### options.transform
+
+**Type**: `function`
+
+**Default**: `undefined`
+
+**Description**: Customize each value in the returned array (or [string](#optionstoRegex)). _(you can also pass this function as the last argument to `fill()`)_.
+
+**Example(s)**
+
+```js
+// add zero padding
+console.log(fill(1, 5, value => String(value).padStart(4, '0')));
+//=> ['0001', '0002', '0003', '0004', '0005']
+```

+# fsevents [![NPM](https://nodei.co/npm/fsevents.png)](https://nodei.co/npm/fsevents/)
+
+Native access to MacOS FSEvents in [Node.js](https://nodejs.org/)
+
+The FSEvents API in MacOS allows applications to register for notifications of
+changes to a given directory tree. It is a very fast and lightweight alternative
+to kqueue.
+
+This is a low-level library. For a cross-platform file watching module that
+uses fsevents, check out [Chokidar](https://github.com/paulmillr/chokidar).
+
+## Installation
+
+Supports only **Node.js v8.16 and higher**.
+
+```sh
+npm install fsevents
+```
+
+## Usage
+
+```js
+const fsevents = require('fsevents');
+const stop = fsevents.watch(__dirname, (path, flags, id) => {
+  const info = fsevents.getInfo(path, flags, id);
+}); // To start observation
+stop(); // To end observation
+```
+
+The callback passed as the second parameter to `.watch` get's called whenever the operating system detects a
+a change in the file system. It takes three arguments:
+
+###### `fsevents.watch(dirname: string, (path: string, flags: number, id: string) => void): () => Promise<undefined>`
+
+ * `path: string` - the item in the filesystem that have been changed
+ * `flags: number` - a numeric value describing what the change was
+ * `id: string` - an unique-id identifying this specific event
+
+ Returns closer callback which when called returns a Promise resolving when the watcher process has been shut down.
+
+###### `fsevents.getInfo(path: string, flags: number, id: string): FsEventInfo`
+
+The `getInfo` function takes the `path`, `flags` and `id` arguments and converts those parameters into a structure
+that is easier to digest to determine what the change was.
+
+The `FsEventsInfo` has the following shape:

+## Changelog
+
+- v2.3 supports Apple Silicon ARM CPUs
+- v2 supports node 8.16+ and reduces package size massively
+- v1.2.8 supports node 6+
+- v1.2.7 supports node 4+
+
+## Troubleshooting
+
+- I'm getting `EBADPLATFORM` `Unsupported platform for fsevents` error.
+- It's fine, nothing is broken. fsevents is macos-only. Other platforms are skipped. If you want to hide this warning, report a bug to NPM bugtracker asking them to hide ebadplatform warnings by default.

+
+Extract the non-magic parent path from a glob string.
+
+## Usage
+
+```js
+var globParent = require('glob-parent');
+
+globParent('path/to/*.js'); // 'path/to'
+globParent('/root/path/to/*.js'); // '/root/path/to'
+globParent('/*.js'); // '/'
+globParent('*.js'); // '.'
+globParent('**/*.js'); // '.'
+globParent('path/{to,from}'); // 'path'
+globParent('path/!(to|from)'); // 'path'
+globParent('path/?(to|from)'); // 'path'
+globParent('path/+(to|from)'); // 'path'
+globParent('path/*(to|from)'); // 'path'
+globParent('path/@(to|from)'); // 'path'
+globParent('path/**/*'); // 'path'
+
+// if provided a non-glob path, returns the nearest dir
+globParent('path/foo/bar.js'); // 'path/foo'
+globParent('path/foo/'); // 'path/foo'
+globParent('path/foo'); // 'path' (see issue #3 for details)
+```
+
+## API
+
+### `globParent(maybeGlobString, [options])`
+
+Takes a string and returns the part of the path before the glob begins. Be aware of Escaping rules and Limitations below.
+
+#### options
+
+```js
+{
+  // Disables the automatic conversion of slashes for Windows
+  flipBackslashes: true
+}
+```
+
+## Escaping
+
+The following characters have special significance in glob patterns and must be escaped if you want them to be treated as regular path characters:
+
+- `?` (question mark) unless used as a path segment alone
+- `*` (asterisk)
+- `|` (pipe)
+- `(` (opening parenthesis)
+- `)` (closing parenthesis)
+- `{` (opening curly brace)
+- `}` (closing curly brace)
+- `[` (opening bracket)
+- `]` (closing bracket)
+
+**Example**
+
+```js
+globParent('foo/[bar]/') // 'foo'
+globParent('foo/\\[bar]/') // 'foo/[bar]'
+```
+
+## Limitations
+
+### Braces & Brackets
+This library attempts a quick and imperfect method of determining which path
+parts have glob magic without fully parsing/lexing the pattern. There are some
+advanced use cases that can trip it up, such as nested braces where the outer
+pair is escaped and the inner one contains a path separator. If you find
+yourself in the unlikely circumstance of being affected by this or need to
+ensure higher-fidelity glob handling in your library, it is recommended that you
+pre-process your input with [expand-braces] and/or [expand-brackets].
+
+### Windows
+Backslashes are not valid path separators for globs. If a path with backslashes
+is provided anyway, for simple cases, glob-parent will replace the path
+separator for you and return the non-glob parent path (now with
+forward-slashes, which are still valid as Windows path separators).
+
+This cannot be used in conjunction with escape characters.
+
+```js
+// BAD
+globParent('C:\\Program Files \\(x86\\)\\*.ext') // 'C:/Program Files /(x86/)'
+
+// GOOD
+globParent('C:/Program Files\\(x86\\)/*.ext') // 'C:/Program Files (x86)'
+```
+
+If you are using escape characters for a pattern without path parts (i.e.
+relative to `cwd`), prefix with `./` to avoid confusing glob-parent.
+
+```js
+// BAD
+globParent('foo \\[bar]') // 'foo '
+globParent('foo \\[bar]*') // 'foo '
+
+// GOOD
+globParent('./foo \\[bar]') // 'foo [bar]'
+globParent('./foo \\[bar]*') // '.'
+```

+
+> Returns true if the value is a finite number.
+
+Please consider following this project's author, [Jon Schlinkert](https://github.com/jonschlinkert), and consider starring the project to show your :heart: and support.
+
+## Install
+
+Install with [npm](https://www.npmjs.com/):
+
+```sh
+$ npm install --save is-number
+```
+
+## Why is this needed?
+
+In JavaScript, it's not always as straightforward as it should be to reliably check if a value is a number. It's common for devs to use `+`, `-`, or `Number()` to cast a string value to a number (for example, when values are returned from user input, regex matches, parsers, etc). But there are many non-intuitive edge cases that yield unexpected results:
+
+```js
+console.log(+[]); //=> 0
+console.log(+''); //=> 0
+console.log(+'   '); //=> 0
+console.log(typeof NaN); //=> 'number'
+```
+
+This library offers a performant way to smooth out edge cases like these.
+
+## Usage
+
+```js
+const isNumber = require('is-number');
+```
+
+See the [tests](./test.js) for more examples.
+
+### true
+
+```js
+isNumber(5e3);               // true
+isNumber(0xff);              // true
+isNumber(-1.1);              // true
+isNumber(0);                 // true
+isNumber(1);                 // true
+isNumber(1.1);               // true
+isNumber(10);                // true
+isNumber(10.10);             // true
+isNumber(100);               // true
+isNumber('-1.1');            // true
+isNumber('0');               // true
+isNumber('012');             // true
+isNumber('0xff');            // true
+isNumber('1');               // true
+isNumber('1.1');             // true
+isNumber('10');              // true
+isNumber('10.10');           // true
+isNumber('100');             // true
+isNumber('5e3');             // true
+isNumber(parseInt('012'));   // true
+isNumber(parseFloat('012')); // true
+```
+
+### False
+
+Everything else is false, as you would expect:
+
+```js
+isNumber(Infinity);          // false
+isNumber(NaN);               // false
+isNumber(null);              // false
+isNumber(undefined);         // false
+isNumber('');                // false
+isNumber('   ');             // false
+isNumber('foo');             // false
+isNumber([1]);               // false
+isNumber([]);                // false
+isNumber(function () {});    // false
+isNumber({});                // false
+```
+
+## Release history
+
+### 7.0.0
+
+* Refactor. Now uses `.isFinite` if it exists.
+* Performance is about the same as v6.0 when the value is a string or number. But it's now 3x-4x faster when the value is not a string or number.
+
+### 6.0.0
+
+* Optimizations, thanks to @benaadams.
+
+### 5.0.0
+
+**Breaking changes**
+
+* removed support for `instanceof Number` and `instanceof String`
+
+## Benchmarks
+
+As with all benchmarks, take these with a grain of salt. See the [benchmarks](./benchmark/index.js) for more detail.

+
+> Normalize slashes in a file path to be posix/unix-like forward slashes. Also condenses repeat slashes to a single slash and removes and trailing slashes, unless disabled.
+
+Please consider following this project's author, [Jon Schlinkert](https://github.com/jonschlinkert), and consider starring the project to show your :heart: and support.
+
+## Install
+
+Install with [npm](https://www.npmjs.com/):
+
+```sh
+$ npm install --save normalize-path
+```
+
+## Usage
+
+```js
+const normalize = require('normalize-path');
+
+console.log(normalize('\\foo\\bar\\baz\\')); 
+//=> '/foo/bar/baz'
+```
+
+**win32 namespaces**
+
+```js
+console.log(normalize('\\\\?\\UNC\\Server01\\user\\docs\\Letter.txt')); 
+//=> '//?/UNC/Server01/user/docs/Letter.txt'
+
+console.log(normalize('\\\\.\\CdRomX')); 
+//=> '//./CdRomX'
+```
+
+**Consecutive slashes**
+
+Condenses multiple consecutive forward slashes (except for leading slashes in win32 namespaces) to a single slash.
+
+```js
+console.log(normalize('.//foo//bar///////baz/')); 
+//=> './foo/bar/baz'
+```
+
+### Trailing slashes
+
+By default trailing slashes are removed. Pass `false` as the last argument to disable this behavior and _**keep** trailing slashes_:
+
+```js
+console.log(normalize('foo\\bar\\baz\\', false)); //=> 'foo/bar/baz/'
+console.log(normalize('./foo/bar/baz/', false)); //=> './foo/bar/baz/'
+```
+
+## Release history
+
+### v3.0
+
+No breaking changes in this release.
+
+* a check was added to ensure that [win32 namespaces](https://msdn.microsoft.com/library/windows/desktop/aa365247(v=vs.85).aspx#namespaces) are handled properly by win32 `path.parse()` after a path has been normalized by this library.
+* a minor optimization was made to simplify how the trailing separator was handled

+# readdirp [![Weekly downloads](https://img.shields.io/npm/dw/readdirp.svg)](https://github.com/paulmillr/readdirp)
+
+Recursive version of [fs.readdir](https://nodejs.org/api/fs.html#fs_fs_readdir_path_options_callback). Exposes a **stream API** and a **promise API**.
+
+
+```sh
+npm install readdirp
+```
+
+```javascript
+const readdirp = require('readdirp');
+
+// Use streams to achieve small RAM & CPU footprint.
+// 1) Streams example with for-await.
+for await (const entry of readdirp('.')) {
+  const {path} = entry;
+  console.log(`${JSON.stringify({path})}`);
+}
+
+// 2) Streams example, non for-await.
+// Print out all JS files along with their size within the current folder & subfolders.
+readdirp('.', {fileFilter: '*.js', alwaysStat: true})
+  .on('data', (entry) => {
+    const {path, stats: {size}} = entry;
+    console.log(`${JSON.stringify({path, size})}`);
+  })
+  // Optionally call stream.destroy() in `warn()` in order to abort and cause 'close' to be emitted
+  .on('warn', error => console.error('non-fatal error', error))
+  .on('error', error => console.error('fatal error', error))
+  .on('end', () => console.log('done'));
+
+// 3) Promise example. More RAM and CPU than streams / for-await.
+const files = await readdirp.promise('.');
+console.log(files.map(file => file.path));
+
+// Other options.
+readdirp('test', {
+  fileFilter: '*.js',
+  directoryFilter: ['!.git', '!*modules']
+  // directoryFilter: (di) => di.basename.length === 9
+  type: 'files_directories',
+  depth: 1
+});
+```
+
+For more examples, check out `examples` directory.
+
+## API
+
+`const stream = readdirp(root[, options])` — **Stream API**
+
+- Reads given root recursively and returns a `stream` of [entry infos](#entryinfo)
+- Optionally can be used like `for await (const entry of stream)` with node.js 10+ (`asyncIterator`).
+- `on('data', (entry) => {})` [entry info](#entryinfo) for every file / dir.
+- `on('warn', (error) => {})` non-fatal `Error` that prevents a file / dir from being processed. Example: inaccessible to the user.
+- `on('error', (error) => {})` fatal `Error` which also ends the stream. Example: illegal options where passed.
+- `on('end')` — we are done. Called when all entries were found and no more will be emitted.
+- `on('close')` — stream is destroyed via `stream.destroy()`.
+  Could be useful if you want to manually abort even on a non fatal error.
+  At that point the stream is no longer `readable` and no more entries, warning or errors are emitted
+- To learn more about streams, consult the very detailed [nodejs streams documentation](https://nodejs.org/api/stream.html)
+  or the [stream-handbook](https://github.com/substack/stream-handbook)
+
+`const entries = await readdirp.promise(root[, options])` — **Promise API**. Returns a list of [entry infos](#entryinfo).
+
+First argument is awalys `root`, path in which to start reading and recursing into subdirectories.
+
+### options
+
+- `fileFilter: ["*.js"]`: filter to include or exclude files. A `Function`, Glob string or Array of glob strings.
+    - **Function**: a function that takes an entry info as a parameter and returns true to include or false to exclude the entry
+    - **Glob string**: a string (e.g., `*.js`) which is matched using [picomatch](https://github.com/micromatch/picomatch), so go there for more
+        information. Globstars (`**`) are not supported since specifying a recursive pattern for an already recursive function doesn't make sense. Negated globs (as explained in the minimatch documentation) are allowed, e.g., `!*.txt` matches everything but text files.
+    - **Array of glob strings**: either need to be all inclusive or all exclusive (negated) patterns otherwise an error is thrown.
+        `['*.json', '*.js']` includes all JavaScript and Json files.
+        `['!.git', '!node_modules']` includes all directories except the '.git' and 'node_modules'.
+    - Directories that do not pass a filter will not be recursed into.
+- `directoryFilter: ['!.git']`: filter to include/exclude directories found and to recurse into. Directories that do not pass a filter will not be recursed into.
+- `depth: 5`: depth at which to stop recursing even if more subdirectories are found
+- `type: 'files'`: determines if data events on the stream should be emitted for `'files'` (default), `'directories'`, `'files_directories'`, or `'all'`. Setting to `'all'` will also include entries for other types of file descriptors like character devices, unix sockets and named pipes.
+- `alwaysStat: false`: always return `stats` property for every file. Default is `false`, readdirp will return `Dirent` entries. Setting it to `true` can double readdir execution time - use it only when you need file `size`, `mtime` etc. Cannot be enabled on node <10.10.0.
+- `lstat: false`: include symlink entries in the stream along with files. When `true`, `fs.lstat` would be used instead of `fs.stat`
+
+### `EntryInfo`
+
+Has the following properties:
+
+- `path: 'assets/javascripts/react.js'`: path to the file/directory (relative to given root)
+- `fullPath: '/Users/dev/projects/app/assets/javascripts/react.js'`: full path to the file/directory found
+- `basename: 'react.js'`: name of the file/directory
+- `dirent: fs.Dirent`: built-in [dir entry object](https://nodejs.org/api/fs.html#fs_class_fs_dirent) - only with `alwaysStat: false`
+- `stats: fs.Stats`: built in [stat object](https://nodejs.org/api/fs.html#fs_class_fs_stats) - only with `alwaysStat: true`
+
+## Changelog
+
+- 3.5 (Oct 13, 2020) disallows recursive directory-based symlinks.
+  Before, it could have entered infinite loop.
+- 3.4 (Mar 19, 2020) adds support for directory-based symlinks.
+- 3.3 (Dec 6, 2019) stabilizes RAM consumption and enables perf management with `highWaterMark` option. Fixes race conditions related to `for-await` looping.
+- 3.2 (Oct 14, 2019) improves performance by 250% and makes streams implementation more idiomatic.
+- 3.1 (Jul 7, 2019) brings `bigint` support to `stat` output on Windows. This is backwards-incompatible for some cases. Be careful. It you use it incorrectly, you'll see "TypeError: Cannot mix BigInt and other types, use explicit conversions".
+- 3.0 brings huge performance improvements and stream backpressure support.
+- Upgrading 2.x to 3.x:
+    - Signature changed from `readdirp(options)` to `readdirp(root, options)`
+    - Replaced callback API with promise API.
+    - Renamed `entryType` option to `type`
+    - Renamed `entryType: 'both'` to `'files_directories'`
+    - `EntryInfo`
+        - Renamed `stat` to `stats`
+            - Emitted only when `alwaysStat: true`
+            - `dirent` is emitted instead of `stats` by default with `alwaysStat: false`
+        - Renamed `name` to `basename`
+        - Removed `parentDir` and `fullParentDir` properties
+- Supported node.js versions:
+    - 3.x: node 8+
+    - 2.x: node 0.6+

+
+> Pass two numbers, get a regex-compatible source string for matching ranges. Validated against more than 2.78 million test assertions.
+
+Please consider following this project's author, [Jon Schlinkert](https://github.com/jonschlinkert), and consider starring the project to show your :heart: and support.
+
+## Install
+
+Install with [npm](https://www.npmjs.com/):
+
+```sh
+$ npm install --save to-regex-range
+```
+
+<details>
+<summary><strong>What does this do?</strong></summary>
+
+<br>
+
+This libary generates the `source` string to be passed to `new RegExp()` for matching a range of numbers.
+
+**Example**
+
+```js
+const toRegexRange = require('to-regex-range');
+const regex = new RegExp(toRegexRange('15', '95'));
+```
+
+A string is returned so that you can do whatever you need with it before passing it to `new RegExp()` (like adding `^` or `$` boundaries, defining flags, or combining it another string).
+
+<br>
+
+</details>
+
+<details>
+<summary><strong>Why use this library?</strong></summary>
+
+<br>
+
+### Convenience
+
+Creating regular expressions for matching numbers gets deceptively complicated pretty fast.
+
+For example, let's say you need a validation regex for matching part of a user-id, postal code, social security number, tax id, etc:
+
+* regex for matching `1` => `/1/` (easy enough)
+* regex for matching `1` through `5` => `/[1-5]/` (not bad...)
+* regex for matching `1` or `5` => `/(1|5)/` (still easy...)
+* regex for matching `1` through `50` => `/([1-9]|[1-4][0-9]|50)/` (uh-oh...)
+* regex for matching `1` through `55` => `/([1-9]|[1-4][0-9]|5[0-5])/` (no prob, I can do this...)
+* regex for matching `1` through `555` => `/([1-9]|[1-9][0-9]|[1-4][0-9]{2}|5[0-4][0-9]|55[0-5])/` (maybe not...)
+* regex for matching `0001` through `5555` => `/(0{3}[1-9]|0{2}[1-9][0-9]|0[1-9][0-9]{2}|[1-4][0-9]{3}|5[0-4][0-9]{2}|55[0-4][0-9]|555[0-5])/` (okay, I get the point!)
+
+The numbers are contrived, but they're also really basic. In the real world you might need to generate a regex on-the-fly for validation.
+
+**Learn more**
+
+If you're interested in learning more about [character classes](http://www.regular-expressions.info/charclass.html) and other regex features, I personally have always found [regular-expressions.info](http://www.regular-expressions.info/charclass.html) to be pretty useful.
+
+### Heavily tested
+
+As of April 07, 2019, this library runs [>1m test assertions](./test/test.js) against generated regex-ranges to provide brute-force verification that results are correct.
+
+Tests run in ~280ms on my MacBook Pro, 2.5 GHz Intel Core i7.
+
+### Optimized
+
+Generated regular expressions are optimized:
+
+* duplicate sequences and character classes are reduced using quantifiers
+* smart enough to use `?` conditionals when number(s) or range(s) can be positive or negative
+* uses fragment caching to avoid processing the same exact string more than once
+
+<br>
+
+</details>
+
+## Usage
+
+Add this library to your javascript application with the following line of code
+
+```js
+const toRegexRange = require('to-regex-range');
+```
+
+The main export is a function that takes two integers: the `min` value and `max` value (formatted as strings or numbers).
+
+```js
+const source = toRegexRange('15', '95');
+//=> 1[5-9]|[2-8][0-9]|9[0-5]
+
+const regex = new RegExp(`^${source}$`);
+console.log(regex.test('14')); //=> false
+console.log(regex.test('50')); //=> true
+console.log(regex.test('94')); //=> true
+console.log(regex.test('96')); //=> false
+```
+
+## Options
+
+### options.capture
+
+**Type**: `boolean`
+
+**Deafault**: `undefined`
+
+Wrap the returned value in parentheses when there is more than one regex condition. Useful when you're dynamically generating ranges.
+
+```js
+console.log(toRegexRange('-10', '10'));
+//=> -[1-9]|-?10|[0-9]
+
+console.log(toRegexRange('-10', '10', { capture: true }));
+//=> (-[1-9]|-?10|[0-9])
+```
+
+### options.shorthand
+
+**Type**: `boolean`
+
+**Deafault**: `undefined`
+
+Use the regex shorthand for `[0-9]`:
+
+```js
+console.log(toRegexRange('0', '999999'));
+//=> [0-9]|[1-9][0-9]{1,5}
+
+console.log(toRegexRange('0', '999999', { shorthand: true }));
+//=> \d|[1-9]\d{1,5}
+```
+
+### options.relaxZeros
+
+**Type**: `boolean`
+
+**Default**: `true`
+
+This option relaxes matching for leading zeros when when ranges are zero-padded.
+
+```js
+const source = toRegexRange('-0010', '0010');
+const regex = new RegExp(`^${source}$`);
+console.log(regex.test('-10')); //=> true
+console.log(regex.test('-010')); //=> true
+console.log(regex.test('-0010')); //=> true
+console.log(regex.test('10')); //=> true
+console.log(regex.test('010')); //=> true
+console.log(regex.test('0010')); //=> true
+```
+
+When `relaxZeros` is false, matching is strict:
+
+```js
+const source = toRegexRange('-0010', '0010', { relaxZeros: false });
+const regex = new RegExp(`^${source}$`);
+console.log(regex.test('-10')); //=> false
+console.log(regex.test('-010')); //=> false
+console.log(regex.test('-0010')); //=> true
+console.log(regex.test('10')); //=> false
+console.log(regex.test('010')); //=> false
+console.log(regex.test('0010')); //=> true
+```

+## Heads up!
+
+**Order of arguments**
+
+When the `min` is larger than the `max`, values will be flipped to create a valid range:
+
+```js
+toRegexRange('51', '29');
+```
+
+Is effectively flipped to:
+
+```js
+toRegexRange('29', '51');
+//=> 29|[3-4][0-9]|5[0-1]
+```
+
+**Steps / increments**
+
+This library does not support steps (increments). A pr to add support would be welcome.
+
+## History
+
+### v2.0.0 - 2017-04-21
+
+**New features**
+
+Adds support for zero-padding!
+
+### v1.0.0
+
+**Optimizations**
+
+Repeating ranges are now grouped using quantifiers. rocessing time is roughly the same, but the generated regex is much smaller, which should result in faster matching.

+//
+// dartMainRunner(main, args):
+//    if this function is defined, the Dart [main] method will not be invoked
+//    directly. Instead, a closure that will invoke [main], and its arguments
+//    [args] is passed to [dartMainRunner].
+//
+// dartDeferredLibraryLoader(uri, successCallback, errorCallback, loadId):
+//    if this function is defined, it will be called when a deferred library
+//    is loaded. It should load and eval the javascript of `uri`, and call
+//    successCallback. If it fails to do so, it should call errorCallback with
+//    an error. The loadId argument is the deferred import that resulted in
+//    this uri being loaded.
+//
+// dartCallInstrumentation(id, qualifiedName):
+//    if this function is defined, it will be called at each entry of a
+//    method or constructor. Used only when compiling programs with
+//    --experiment-call-instrumentation.

+ *
+ * This is the process of resolving a load using a custom importer:

+ * - It calls [[canonicalize]] with `"db:foo/bar/baz"`.

+ * - If the compiler has already loaded a stylesheet with this canonical URL, it

+ * - Otherwise, it calls [[load]] with `new URL("db:foo/bar/baz/_index.scss")`.
+ * - [[load]] returns an [[ImporterResult]] that the compiler uses as the

+ * @example Code Sample

+   * If `url` is recognized by this importer, returns its canonical format.
+   *
+   * If Sass has already loaded a stylesheet with the returned canonical URL, it
+   * re-uses the existing parse tree (and the loaded module for `@use`). This
+   * means that importers **must ensure** that the same canonical URL always
+   * refers to the same stylesheet, *even across different importers*. As such,
+   * importers are encouraged to use unique URL schemes to disambiguate between
+   * one another.
+   *
+   * As much as possible, custom importers should canonicalize URLs the same way
+   * as the built-in filesystem importer:
+   *
+   * - The importer should look for stylesheets by adding the prefix `_` to the
+   *   URL's basename, and by adding the extensions `.sass` and `.scss` if the
+   *   URL doesn't already have one of those extensions. For example, if the
+   *   URL was `foo/bar/baz`, the importer would look for:
+   *   - `foo/bar/baz.sass`
+   *   - `foo/bar/baz.scss`
+   *   - `foo/bar/_baz.sass`
+   *   - `foo/bar/_baz.scss`
+   *
+   *   If the URL was `foo/bar/baz.scss`, the importer would just look for:
+   *   - `foo/bar/baz.scss`
+   *   - `foo/bar/_baz.scss`
+   *
+   *   If the importer finds a stylesheet at more than one of these URLs, it
+   *   should throw an exception indicating that the URL is ambiguous. Note that
+   *   if the extension is explicitly specified, a stylesheet with the opposite
+   *   extension is allowed to exist.
+   *
+   * - If none of the possible paths is valid, the importer should perform the
+   *   same resolution on the URL followed by `/index`. In the example above,
+   *   it would look for:
+   *   - `foo/bar/baz/index.sass`
+   *   - `foo/bar/baz/index.scss`
+   *   - `foo/bar/baz/_index.sass`
+   *   - `foo/bar/baz/_index.scss`
+   *
+   *   As above, if the importer finds a stylesheet at more than one of these
+   *   URLs, it should throw an exception indicating that the import is
+   *   ambiguous.
+   *
+   * If no stylesheets are found, the importer should return `null`.
+   *
+   * Calling [[canonicalize]] multiple times with the same URL must return the
+   * same result. Calling [[canonicalize]] with a URL returned by a previous
+   * call to [[canonicalize]] must return that URL.
+   *
+   * Relative loads in stylesheets loaded from an importer are handled by
+   * resolving the loaded URL relative to the canonical URL of the stylesheet
+   * that contains it, and passing that URL back to the importer's
+   * [[canonicalize]] method. For example, suppose the "Resolving a Load"
+   * example {@link Importer | above} returned a stylesheet that contained
+   * `@use "mixins"`:
+   *
+   * - The compiler resolves the URL `mixins` relative to the current
+   *   stylesheet's canonical URL `db:foo/bar/baz/_index.scss` to get
+   *   `db:foo/bar/baz/mixins`.
+   * - It calls [[canonicalize]] with `"db:foo/bar/baz/mixins"`.
+   * - [[canonicalize]] returns `new URL("db:foo/bar/baz/_mixins.scss")`.
+   *
+   * Because of this, [[canonicalize]] must return a meaningful result when
+   * called with a URL relative to one returned by an earlier call to
+   * [[canonicalize]].
+   *
+   * @param url - The loaded URL. Since this might be relative, it's represented
+   * as a string rather than a [[URL]] object.
+   *
+   * @param options.fromImport - Whether this is being invoked because of a Sass

+   *
+   * Functions are passed JavaScript representations of [Sass value
+   * types](https://sass-lang.com/documentation/js-api#value-types), and must
+   * return the same.
+   *
+   * When writing custom functions, it's important to make them as user-friendly
+   * and as close to the standards set by Sass's core functions as possible. Some
+   * good guidelines to follow include:
+   *
+   * * Use `Value.assert*` methods, like [[Value.assertString]], to cast untyped
+   *   `Value` objects to more specific types. For values that were passed
+   *   directly as arguments, pass in the argument name as well. This ensures
+   *   that the user gets good error messages when they pass in the wrong type
+   *   to your function.
+   *
+   * * Individual classes may have more specific `assert*` methods, like
+   *   [[SassNumber.assertInt]], which should be used when possible.
+   *
+   * * In Sass, every value counts as a list. Rather than trying to detect the
+   *   [[SassList]] type, you should use [[Value.asList]] to treat all values as
+   *   lists.
+   *
+   * * When manipulating values like lists, strings, and numbers that have
+   *   metadata (comma versus space separated, bracketed versus unbracketed,
+   *   quoted versus unquoted, units), the output metadata should match the
+   *   input metadata.
+   *
+   * * When in doubt, lists should default to comma-separated, strings should
+   *   default to quoted, and numbers should default to unitless.
+   *
+   * * In Sass, lists and strings use one-based indexing and use negative
+   *   indices to index from the end of value. Functions should follow these
+   *   conventions. [[Value.sassIndexToListIndex]] and
+   *   [[SassString.sassIndexToStringIndex]] can be used to do this
+   *   automatically.
+   *
+   * * String indexes in Sass refer to Unicode code points while JavaScript
+   *   string indices refer to UTF-16 code units. For example, the character
+   *   U+1F60A SMILING FACE WITH SMILING EYES is a single Unicode code point but
+   *   is represented in UTF-16 as two code units (`0xD83D` and `0xDE0A`). So in
+   *   JavaScript, `"a😊b".charCodeAt(1)` returns `0xD83D`, whereas in Sass
+   *   `str-slice("a😊b", 1, 1)` returns `"😊"`. Functions should follow Sass's
+   *   convention. [[SassString.sassIndexToStringIndex]] can be used to do this
+   *   automatically, and the [[SassString.sassLength]] getter can be used to
+   *   access a string's length in code points.
+   *
+   * @example
+   *
+   * ```js
+   * sass.compileString(`
+   * h1 {
+   *   font-size: pow(2, 5) * 1px;
+   * }`, {
+   *   functions: {
+   *     // Note: in real code, you should use `math.pow()` from the built-in
+   *     // `sass:math` module.
+   *     'pow($base, $exponent)': function(args) {
+   *       const base = args[0].assertNumber('base').assertNoUnits('base');

+   *           args[1].assertNumber('exponent').assertNoUnits('exponent');

-# scss-tokenizer
-A tokenzier for Sass' SCSS syntax
-
-![https://travis-ci.org/sasstools/scss-tokenizer.svg?branch=master](https://img.shields.io/travis/sasstools/scss-tokenizer.svg)
-![https://www.npmjs.com/package/scss-tokenizer](https://img.shields.io/npm/v/scss-tokenizer.svg)

-![](https://img.shields.io/github/license/sasstools/scss-tokenizer.svg)
-
-# Install
-
-```
-npm install scss-tokenizer
-```
-
-# Usage
-
-```js
-var scss = require('scss-tokenizer');
-scss.tokenize(css);
-```
-
-# API
-
-### `tokenize`
-
-Tokenizes source `css` and returns an ordered array of tokens with positional
-data.
-
-```js
-var tokenizer = require('scss-tokenizer');
-var tokens = tokenize.tokenize(css);
-```
-
-Arguments:
-
-* `css (string|#toString)`: String with input CSS or any object
-  with `toString()` method, like file stream.
-* `opts (object) optional`: options:
-  * `from`: the path to the source CSS file. You should always set `from`,
-    because it is used in map generation and in syntax error messages.
-
-# Test
-
-```
-npm test
-```
-
-## Attribution
-
-This project started as a fork of the [PostCSS](https://github.com/postcss/postcss) tokenizer.

-
-When you want to fire an event no matter how a process exits:
-
-* reaching the end of execution.
-* explicitly having `process.exit(code)` called.
-* having `process.kill(pid, sig)` called.
-* receiving a fatal signal from outside the process
-
-Use `signal-exit`.
-
-```js
-var onExit = require('signal-exit')
-
-onExit(function (code, signal) {
-  console.log('process exited!')
-})
-```
-
-## API
-
-`var remove = onExit(function (code, signal) {}, options)`
-
-The return value of the function is a function that will remove the
-handler.
-
-Note that the function *only* fires for signals if the signal would
-cause the proces to exit.  That is, there are no other listeners, and
-it is a fatal signal.
-
-## Options
-
-* `alwaysLast`: Run this handler after any other signal or exit
-  handlers.  This causes `process.emit` to be monkeypatched.

+## 0.5.1
+
+* Fix latent bugs in IndexedSourceMapConsumer.prototype._parseMappings. See
+  ff05274becc9e6e1295ed60f3ea090d31d843379.
+
+## 0.5.0
+
+* Node 0.8 is no longer supported.
+
+* Use webpack instead of dryice for bundling.
+
+* Big speedups serializing source maps. See pull request #203.
+
+* Fix a bug with `SourceMapConsumer.prototype.sourceContentFor` and sources that
+  explicitly start with the source root. See issue #199.
+
+## 0.4.4
+
+* Fix an issue where using a `SourceMapGenerator` after having created a
+  `SourceMapConsumer` from it via `SourceMapConsumer.fromSourceMap` failed. See
+  issue #191.
+
+* Fix an issue with where `SourceMapGenerator` would mistakenly consider
+  different mappings as duplicates of each other and avoid generating them. See
+  issue #192.
+
+## 0.4.3
+
+* A very large number of performance improvements, particularly when parsing
+  source maps. Collectively about 75% of time shaved off of the source map
+  parsing benchmark!
+
+* Fix a bug in `SourceMapConsumer.prototype.allGeneratedPositionsFor` and fuzzy
+  searching in the presence of a column option. See issue #177.
+
+* Fix a bug with joining a source and its source root when the source is above
+  the root. See issue #182.
+
+* Add the `SourceMapConsumer.prototype.hasContentsOfAllSources` method to
+  determine when all sources' contents are inlined into the source map. See
+  issue #190.
+
+## 0.4.2
+
+* Add an `.npmignore` file so that the benchmarks aren't pulled down by
+  dependent projects. Issue #169.
+
+* Add an optional `column` argument to
+  `SourceMapConsumer.prototype.allGeneratedPositionsFor` and better handle lines
+  with no mappings. Issues #172 and #173.
+
+## 0.4.1
+
+* Fix accidentally defining a global variable. #170.
+
+## 0.4.0
+
+* The default direction for fuzzy searching was changed back to its original
+  direction. See #164.
+
+* There is now a `bias` option you can supply to `SourceMapConsumer` to control
+  the fuzzy searching direction. See #167.
+
+* About an 8% speed up in parsing source maps. See #159.
+
+* Added a benchmark for parsing and generating source maps.
+
+## 0.3.0
+
+* Change the default direction that searching for positions fuzzes when there is
+  not an exact match. See #154.
+
+* Support for environments using json2.js for JSON serialization. See #156.
+
+## 0.2.0
+
+* Support for consuming "indexed" source maps which do not have any remote
+  sections. See pull request #127. This introduces a minor backwards
+  incompatibility if you are monkey patching `SourceMapConsumer.prototype`
+  methods.
+
+## 0.1.43
+
+* Performance improvements for `SourceMapGenerator` and `SourceNode`. See issue
+  #148 for some discussion and issues #150, #151, and #152 for implementations.

+  prefix. See issue #145 and [Bug 1090768](bugzil.la/1090768).
+
+* Add the `SourceMapConsumer.prototype.computeColumnSpans` method to compute the
+  column span of each mapping.
+
+* Add the `SourceMapConsumer.prototype.allGeneratedPositionsFor` method to find
+  all generated positions associated with a given original source and line.
+
+## 0.1.40
+
+* Performance improvements for parsing source maps in SourceMapConsumer.
+
+## 0.1.39
+
+* Fix a bug where setting a source's contents to null before any source content
+  had been set before threw a TypeError. See issue #131.
+
+## 0.1.38
+
+* Fix a bug where finding relative paths from an empty path were creating
+  absolute paths. See issue #129.
+
+## 0.1.37
+
+* Fix a bug where if the source root was an empty string, relative source paths
+  would turn into absolute source paths. Issue #124.
+
+## 0.1.36
+
+* Allow the `names` mapping property to be an empty string. Issue #121.
+
+## 0.1.35
+
+* A third optional parameter was added to `SourceNode.fromStringWithSourceMap`
+  to specify a path that relative sources in the second parameter should be
+  relative to. Issue #105.
+
+* If no file property is given to a `SourceMapGenerator`, then the resulting
+  source map will no longer have a `null` file property. The property will
+  simply not exist. Issue #104.
+
+* Fixed a bug where consecutive newlines were ignored in `SourceNode`s.
+  Issue #116.
+
+## 0.1.34
+

+* Fix some edge cases surrounding path joining and URL resolution.
+
+* Add a third parameter for relative path to
+  `SourceMapGenerator.prototype.applySourceMap`.
+
+* Fix issues with mappings and EOLs.
+
+## 0.1.32
+
+* Fixed a bug where SourceMapConsumer couldn't handle negative relative columns
+  (issue 92).
+
+* Fixed test runner to actually report number of failed tests as its process
+  exit code.
+
+* Fixed a typo when reporting bad mappings (issue 87).
+
+## 0.1.31

+  location.
+
+* Support Sass source maps (which at the time of writing deviate from the spec
+  in small ways) in SourceMapConsumer.
+
+## 0.1.30
+
+* Do not join source root with a source, when the source is a data URI.
+
+* Extend the test runner to allow running single specific test files at a time.
+
+* Performance improvements in `SourceNode.prototype.walk` and
+  `SourceMapConsumer.prototype.eachMapping`.
+
+* Source map browser builds will now work inside Workers.
+
+* Better error messages when attempting to add an invalid mapping to a
+  `SourceMapGenerator`.
+
+## 0.1.29
+
+* Allow duplicate entries in the `names` and `sources` arrays of source maps
+  (usually from TypeScript) we are parsing. Fixes github issue 72.

+# Source Map JS
+
+[![NPM](https://nodei.co/npm/source-map-js.png?downloads=true&downloadRank=true)](https://www.npmjs.com/package/source-map-js)
+
+Difference between original [source-map](https://github.com/mozilla/source-map):
+
+> TL,DR: it's fork of original source-map@0.6, but with perfomance optimizations.
+
+This journey starts from [source-map@0.7.0](https://github.com/mozilla/source-map/blob/master/CHANGELOG.md#070). Some part of it was rewritten to Rust and WASM and API became async.
+
+It's still a major block for many libraries like PostCSS or Sass for example because they need to migrate the whole API to the async way. This is the reason why 0.6.1 has 2x more downloads than 0.7.3 while it's faster several times.
+
+![Downloads count](media/downloads.png)
+
+More important that WASM version has some optimizations in JS code too. This is why [community asked to create branch for 0.6 version](https://github.com/mozilla/source-map/issues/324) and port these optimizations but, sadly, the answer was «no». A bit later I discovered [the issue](https://github.com/mozilla/source-map/issues/370) created by [Ben Rothman (@benthemonkey)](https://github.com/benthemonkey) with no response at all.
+
+[Roman Dvornov (@lahmatiy)](https://github.com/lahmatiy) wrote a [serveral posts](https://t.me/gorshochekvarit/76) (russian, only, sorry) about source-map library in his own Telegram channel. He mentioned the article [«Maybe you don't need Rust and WASM to speed up your JS»](https://mrale.ph/blog/2018/02/03/maybe-you-dont-need-rust-to-speed-up-your-js.html) written by [Vyacheslav Egorov (@mraleph)](https://github.com/mraleph). This article contains optimizations and hacks that lead to almost the same performance compare to WASM implementation.
+
+I decided to fork the original source-map and port these optimizations from the article and several others PR from the original source-map.
+
+---------
+
+This is a library to generate and consume the source map format
+[described here][format].

+### Consuming a source map
+
+```js
+var rawSourceMap = {
+  version: 3,
+  file: 'min.js',
+  names: ['bar', 'baz', 'n'],
+  sources: ['one.js', 'two.js'],
+  sourceRoot: 'http://example.com/www/js/',

+### Generating a source map
+
+In depth guide:
+[**Compiling to JavaScript, and Debugging with Source Maps**](https://hacks.mozilla.org/2013/05/compiling-to-javascript-and-debugging-with-source-maps/)
+
+#### With SourceNode (high level API)
+
+```js
+function compile(ast) {
+  switch (ast.type) {
+  case 'BinaryExpression':
+    return new SourceNode(
+      ast.location.line,
+      ast.location.column,
+      ast.location.source,
+      [compile(ast.left), " + ", compile(ast.right)]
+    );
+  case 'Literal':
+    return new SourceNode(
+      ast.location.line,
+      ast.location.column,
+      ast.location.source,
+      String(ast.value)
+    );
+  // ...
+  default:
+    throw new Error("Bad AST");
+  }
+}
+
+var ast = parse("40 + 2", "add.js");
+console.log(compile(ast).toStringWithSourceMap({
+  file: 'add.js'
+}));
+// { code: '40 + 2',
+//   map: [object SourceMapGenerator] }
+```
+
+#### With SourceMapGenerator (low level API)
+
+```js
+var map = new SourceMapGenerator({
+  file: "source-mapped.js"
+});
+
+map.addMapping({
+  generated: {
+    line: 10,
+    column: 35
+  },
+  source: "foo.js",
+  original: {
+    line: 33,
+    column: 2
+  },
+  name: "christopher"
+});
+
+console.log(map.toString());
+// '{"version":3,"file":"source-mapped.js","sources":["foo.js"],"names":["christopher"],"mappings":";;;;;;;;;mCAgCEA"}'
+```
+
+## API
+
+Get a reference to the module:
+
+```js
+// Node.js
+var sourceMap = require('source-map');
+
+// Browser builds
+var sourceMap = window.sourceMap;
+
+// Inside Firefox
+const sourceMap = require("devtools/toolkit/sourcemap/source-map.js");
+```
+
+### SourceMapConsumer
+
+A SourceMapConsumer instance represents a parsed source map which we can query
+for information about the original file positions by giving it a file position
+in the generated source.
+
+#### new SourceMapConsumer(rawSourceMap)
+
+The only parameter is the raw source map (either as a string which can be
+`JSON.parse`'d, or an object). According to the spec, source maps have the
+following attributes:
+
+* `version`: Which version of the source map spec this map is following.
+
+* `sources`: An array of URLs to the original source files.
+
+* `names`: An array of identifiers which can be referenced by individual
+  mappings.
+
+* `sourceRoot`: Optional. The URL root from which all sources are relative.
+
+* `sourcesContent`: Optional. An array of contents of the original source files.
+
+* `mappings`: A string of base64 VLQs which contain the actual mappings.
+
+* `file`: Optional. The generated filename this source map is associated with.
+
+```js
+var consumer = new sourceMap.SourceMapConsumer(rawSourceMapJsonData);
+```
+
+#### SourceMapConsumer.prototype.computeColumnSpans()
+
+Compute the last column for each generated mapping. The last column is
+inclusive.
+
+```js
+// Before:
+consumer.allGeneratedPositionsFor({ line: 2, source: "foo.coffee" })
+// [ { line: 2,
+//     column: 1 },
+//   { line: 2,
+//     column: 10 },
+//   { line: 2,
+//     column: 20 } ]
+
+consumer.computeColumnSpans();
+
+// After:
+consumer.allGeneratedPositionsFor({ line: 2, source: "foo.coffee" })
+// [ { line: 2,
+//     column: 1,
+//     lastColumn: 9 },
+//   { line: 2,
+//     column: 10,
+//     lastColumn: 19 },
+//   { line: 2,
+//     column: 20,
+//     lastColumn: Infinity } ]
+
+```
+
+#### SourceMapConsumer.prototype.originalPositionFor(generatedPosition)
+
+Returns the original source, line, and column information for the generated
+source's line and column positions provided. The only argument is an object with
+the following properties:
+
+* `line`: The line number in the generated source.  Line numbers in
+  this library are 1-based (note that the underlying source map
+  specification uses 0-based line numbers -- this library handles the
+  translation).
+
+* `column`: The column number in the generated source.  Column numbers
+  in this library are 0-based.
+
+* `bias`: Either `SourceMapConsumer.GREATEST_LOWER_BOUND` or
+  `SourceMapConsumer.LEAST_UPPER_BOUND`. Specifies whether to return the closest
+  element that is smaller than or greater than the one we are searching for,
+  respectively, if the exact element cannot be found.  Defaults to
+  `SourceMapConsumer.GREATEST_LOWER_BOUND`.
+
+and an object is returned with the following properties:
+
+* `source`: The original source file, or null if this information is not
+  available.
+
+* `line`: The line number in the original source, or null if this information is
+  not available.  The line number is 1-based.
+
+* `column`: The column number in the original source, or null if this
+  information is not available.  The column number is 0-based.
+
+* `name`: The original identifier, or null if this information is not available.
+
+```js
+consumer.originalPositionFor({ line: 2, column: 10 })
+// { source: 'foo.coffee',
+//   line: 2,
+//   column: 2,
+//   name: null }
+
+consumer.originalPositionFor({ line: 99999999999999999, column: 999999999999999 })
+// { source: null,
+//   line: null,
+//   column: null,
+//   name: null }
+```
+
+#### SourceMapConsumer.prototype.generatedPositionFor(originalPosition)
+
+Returns the generated line and column information for the original source,
+line, and column positions provided. The only argument is an object with
+the following properties:
+
+* `source`: The filename of the original source.
+
+* `line`: The line number in the original source.  The line number is
+  1-based.
+
+* `column`: The column number in the original source.  The column
+  number is 0-based.
+
+and an object is returned with the following properties:
+
+* `line`: The line number in the generated source, or null.  The line
+  number is 1-based.
+
+* `column`: The column number in the generated source, or null.  The
+  column number is 0-based.
+
+```js
+consumer.generatedPositionFor({ source: "example.js", line: 2, column: 10 })
+// { line: 1,
+//   column: 56 }
+```
+
+#### SourceMapConsumer.prototype.allGeneratedPositionsFor(originalPosition)
+
+Returns all generated line and column information for the original source, line,
+and column provided. If no column is provided, returns all mappings
+corresponding to a either the line we are searching for or the next closest line
+that has any mappings. Otherwise, returns all mappings corresponding to the
+given line and either the column we are searching for or the next closest column
+that has any offsets.
+
+The only argument is an object with the following properties:
+
+* `source`: The filename of the original source.
+
+* `line`: The line number in the original source.  The line number is
+  1-based.
+
+* `column`: Optional. The column number in the original source.  The
+  column number is 0-based.
+
+and an array of objects is returned, each with the following properties:
+
+* `line`: The line number in the generated source, or null.  The line
+  number is 1-based.
+
+* `column`: The column number in the generated source, or null.  The
+  column number is 0-based.
+
+```js
+consumer.allGeneratedpositionsfor({ line: 2, source: "foo.coffee" })
+// [ { line: 2,
+//     column: 1 },
+//   { line: 2,
+//     column: 10 },
+//   { line: 2,
+//     column: 20 } ]
+```
+
+#### SourceMapConsumer.prototype.hasContentsOfAllSources()
+
+Return true if we have the embedded source content for every source listed in
+the source map, false otherwise.
+
+In other words, if this method returns `true`, then
+`consumer.sourceContentFor(s)` will succeed for every source `s` in
+`consumer.sources`.
+
+```js
+// ...
+if (consumer.hasContentsOfAllSources()) {
+  consumerReadyCallback(consumer);
+} else {
+  fetchSources(consumer, consumerReadyCallback);
+}
+// ...
+```
+
+#### SourceMapConsumer.prototype.sourceContentFor(source[, returnNullOnMissing])
+
+Returns the original source content for the source provided. The only
+argument is the URL of the original source file.
+
+If the source content for the given source is not found, then an error is
+thrown. Optionally, pass `true` as the second param to have `null` returned
+instead.
+
+```js
+consumer.sources
+// [ "my-cool-lib.clj" ]
+
+consumer.sourceContentFor("my-cool-lib.clj")
+// "..."
+
+consumer.sourceContentFor("this is not in the source map");
+// Error: "this is not in the source map" is not in the source map
+
+consumer.sourceContentFor("this is not in the source map", true);
+// null
+```
+
+#### SourceMapConsumer.prototype.eachMapping(callback, context, order)
+
+Iterate over each mapping between an original source/line/column and a
+generated line/column in this source map.
+
+* `callback`: The function that is called with each mapping. Mappings have the
+  form `{ source, generatedLine, generatedColumn, originalLine, originalColumn,
+  name }`
+
+* `context`: Optional. If specified, this object will be the value of `this`
+  every time that `callback` is called.
+
+* `order`: Either `SourceMapConsumer.GENERATED_ORDER` or
+  `SourceMapConsumer.ORIGINAL_ORDER`. Specifies whether you want to iterate over
+  the mappings sorted by the generated file's line/column order or the
+  original's source/line/column order, respectively. Defaults to
+  `SourceMapConsumer.GENERATED_ORDER`.
+
+```js
+consumer.eachMapping(function (m) { console.log(m); })
+// ...
+// { source: 'illmatic.js',
+//   generatedLine: 1,
+//   generatedColumn: 0,
+//   originalLine: 1,
+//   originalColumn: 0,
+//   name: null }
+// { source: 'illmatic.js',
+//   generatedLine: 2,
+//   generatedColumn: 0,
+//   originalLine: 2,
+//   originalColumn: 0,
+//   name: null }
+// ...
+```
+### SourceMapGenerator
+
+An instance of the SourceMapGenerator represents a source map which is being
+built incrementally.
+
+#### new SourceMapGenerator([startOfSourceMap])
+
+You may pass an object with the following properties:
+
+* `file`: The filename of the generated source that this source map is
+  associated with.
+
+* `sourceRoot`: A root for all relative URLs in this source map.
+
+* `skipValidation`: Optional. When `true`, disables validation of mappings as
+  they are added. This can improve performance but should be used with
+  discretion, as a last resort. Even then, one should avoid using this flag when
+  running tests, if possible.
+
+```js
+var generator = new sourceMap.SourceMapGenerator({
+  file: "my-generated-javascript-file.js",
+  sourceRoot: "http://example.com/app/js/"
+});
+```
+
+#### SourceMapGenerator.fromSourceMap(sourceMapConsumer)
+
+Creates a new `SourceMapGenerator` from an existing `SourceMapConsumer` instance.
+
+* `sourceMapConsumer` The SourceMap.
+
+```js
+var generator = sourceMap.SourceMapGenerator.fromSourceMap(consumer);
+```
+
+#### SourceMapGenerator.prototype.addMapping(mapping)
+
+Add a single mapping from original source line and column to the generated
+source's line and column for this source map being created. The mapping object
+should have the following properties:
+
+* `generated`: An object with the generated line and column positions.
+
+* `original`: An object with the original line and column positions.
+
+* `source`: The original source file (relative to the sourceRoot).
+
+* `name`: An optional original token name for this mapping.
+
+```js
+generator.addMapping({
+  source: "module-one.scm",
+  original: { line: 128, column: 0 },
+  generated: { line: 3, column: 456 }
+})
+```
+
+#### SourceMapGenerator.prototype.setSourceContent(sourceFile, sourceContent)
+
+Set the source content for an original source file.
+
+* `sourceFile` the URL of the original source file.
+
+* `sourceContent` the content of the source file.
+
+```js
+generator.setSourceContent("module-one.scm",
+                           fs.readFileSync("path/to/module-one.scm"))
+```
+
+#### SourceMapGenerator.prototype.applySourceMap(sourceMapConsumer[, sourceFile[, sourceMapPath]])
+
+Applies a SourceMap for a source file to the SourceMap.
+Each mapping to the supplied source file is rewritten using the
+supplied SourceMap. Note: The resolution for the resulting mappings
+is the minimum of this map and the supplied map.
+
+* `sourceMapConsumer`: The SourceMap to be applied.
+
+* `sourceFile`: Optional. The filename of the source file.
+  If omitted, sourceMapConsumer.file will be used, if it exists.
+  Otherwise an error will be thrown.
+
+* `sourceMapPath`: Optional. The dirname of the path to the SourceMap
+  to be applied. If relative, it is relative to the SourceMap.
+
+  This parameter is needed when the two SourceMaps aren't in the same
+  directory, and the SourceMap to be applied contains relative source
+  paths. If so, those relative source paths need to be rewritten
+  relative to the SourceMap.
+
+  If omitted, it is assumed that both SourceMaps are in the same directory,
+  thus not needing any rewriting. (Supplying `'.'` has the same effect.)
+
+#### SourceMapGenerator.prototype.toString()
+
+Renders the source map being generated to a string.
+
+```js
+generator.toString()
+// '{"version":3,"sources":["module-one.scm"],"names":[],"mappings":"...snip...","file":"my-generated-javascript-file.js","sourceRoot":"http://example.com/app/js/"}'
+```
+
+### SourceNode
+
+SourceNodes provide a way to abstract over interpolating and/or concatenating
+snippets of generated JavaScript source code, while maintaining the line and
+column information associated between those snippets and the original source
+code. This is useful as the final intermediate representation a compiler might
+use before outputting the generated JS and source map.
+
+#### new SourceNode([line, column, source[, chunk[, name]]])
+
+* `line`: The original line number associated with this source node, or null if
+  it isn't associated with an original line.  The line number is 1-based.
+
+* `column`: The original column number associated with this source node, or null
+  if it isn't associated with an original column.  The column number
+  is 0-based.
+
+* `source`: The original source's filename; null if no filename is provided.
+
+* `chunk`: Optional. Is immediately passed to `SourceNode.prototype.add`, see
+  below.
+
+* `name`: Optional. The original identifier.
+
+```js
+var node = new SourceNode(1, 2, "a.cpp", [
+  new SourceNode(3, 4, "b.cpp", "extern int status;\n"),
+  new SourceNode(5, 6, "c.cpp", "std::string* make_string(size_t n);\n"),
+  new SourceNode(7, 8, "d.cpp", "int main(int argc, char** argv) {}\n"),
+]);
+```
+
+#### SourceNode.fromStringWithSourceMap(code, sourceMapConsumer[, relativePath])
+
+Creates a SourceNode from generated code and a SourceMapConsumer.
+
+* `code`: The generated code
+
+* `sourceMapConsumer` The SourceMap for the generated code
+
+* `relativePath` The optional path that relative sources in `sourceMapConsumer`
+  should be relative to.
+
+```js
+var consumer = new SourceMapConsumer(fs.readFileSync("path/to/my-file.js.map", "utf8"));
+var node = SourceNode.fromStringWithSourceMap(fs.readFileSync("path/to/my-file.js"),
+                                              consumer);
+```
+
+#### SourceNode.prototype.add(chunk)
+
+Add a chunk of generated JS to this source node.
+
+* `chunk`: A string snippet of generated JS code, another instance of
+   `SourceNode`, or an array where each member is one of those things.
+
+```js
+node.add(" + ");
+node.add(otherNode);
+node.add([leftHandOperandNode, " + ", rightHandOperandNode]);
+```
+
+#### SourceNode.prototype.prepend(chunk)
+
+Prepend a chunk of generated JS to this source node.
+
+* `chunk`: A string snippet of generated JS code, another instance of
+   `SourceNode`, or an array where each member is one of those things.
+
+```js
+node.prepend("/** Build Id: f783haef86324gf **/\n\n");
+```
+
+#### SourceNode.prototype.setSourceContent(sourceFile, sourceContent)
+
+Set the source content for a source file. This will be added to the
+`SourceMap` in the `sourcesContent` field.
+
+* `sourceFile`: The filename of the source file
+
+* `sourceContent`: The content of the source file
+
+```js
+node.setSourceContent("module-one.scm",
+                      fs.readFileSync("path/to/module-one.scm"))
+```
+
+#### SourceNode.prototype.walk(fn)
+
+Walk over the tree of JS snippets in this node and its children. The walking
+function is called once for each snippet of JS and is passed that snippet and
+the its original associated source's line/column location.
+
+* `fn`: The traversal function.
+
+```js
+var node = new SourceNode(1, 2, "a.js", [
+  new SourceNode(3, 4, "b.js", "uno"),
+  "dos",
+  [
+    "tres",
+    new SourceNode(5, 6, "c.js", "quatro")
+  ]
+]);
+
+node.walk(function (code, loc) { console.log("WALK:", code, loc); })
+// WALK: uno { source: 'b.js', line: 3, column: 4, name: null }
+// WALK: dos { source: 'a.js', line: 1, column: 2, name: null }
+// WALK: tres { source: 'a.js', line: 1, column: 2, name: null }
+// WALK: quatro { source: 'c.js', line: 5, column: 6, name: null }
+```
+
+#### SourceNode.prototype.walkSourceContents(fn)
+
+Walk over the tree of SourceNodes. The walking function is called for each
+source file content and is passed the filename and source content.
+
+* `fn`: The traversal function.
+
+```js
+var a = new SourceNode(1, 2, "a.js", "generated from a");
+a.setSourceContent("a.js", "original a");
+var b = new SourceNode(1, 2, "b.js", "generated from b");
+b.setSourceContent("b.js", "original b");
+var c = new SourceNode(1, 2, "c.js", "generated from c");
+c.setSourceContent("c.js", "original c");
+
+var node = new SourceNode(null, null, null, [a, b, c]);
+node.walkSourceContents(function (source, contents) { console.log("WALK:", source, ":", contents); })
+// WALK: a.js : original a
+// WALK: b.js : original b
+// WALK: c.js : original c
+```
+
+#### SourceNode.prototype.join(sep)
+
+Like `Array.prototype.join` except for SourceNodes. Inserts the separator
+between each of this source node's children.
+
+* `sep`: The separator.
+
+```js
+var lhs = new SourceNode(1, 2, "a.rs", "my_copy");
+var operand = new SourceNode(3, 4, "a.rs", "=");
+var rhs = new SourceNode(5, 6, "a.rs", "orig.clone()");
+
+var node = new SourceNode(null, null, null, [ lhs, operand, rhs ]);
+var joinedNode = node.join(" ");
+```
+
+#### SourceNode.prototype.replaceRight(pattern, replacement)
+
+Call `String.prototype.replace` on the very right-most source snippet. Useful
+for trimming white space from the end of a source node, etc.
+
+* `pattern`: The pattern to replace.
+
+* `replacement`: The thing to replace the pattern with.
+
+```js
+// Trim trailing white space.
+node.replaceRight(/\s*$/, "");
+```
+
+#### SourceNode.prototype.toString()
+
+Return the string representation of this source node. Walks over the tree and
+concatenates all the various snippets together to one string.
+
+```js
+var node = new SourceNode(1, 2, "a.js", [
+  new SourceNode(3, 4, "b.js", "uno"),
+  "dos",
+  [
+    "tres",
+    new SourceNode(5, 6, "c.js", "quatro")
+  ]
+]);
+
+node.toString()
+// 'unodostresquatro'
+```
+
+#### SourceNode.prototype.toStringWithSourceMap([startOfSourceMap])
+
+Returns the string representation of this tree of source nodes, plus a
+SourceMapGenerator which contains all the mappings between the generated and
+original sources.
+
+The arguments are the same as those to `new SourceMapGenerator`.
+
+```js
+var node = new SourceNode(1, 2, "a.js", [
+  new SourceNode(3, 4, "b.js", "uno"),
+  "dos",
+  [
+    "tres",
+    new SourceNode(5, 6, "c.js", "quatro")
+  ]
+]);
+
+node.toStringWithSourceMap({ file: "my-output-file.js" })
+// { code: 'unodostresquatro',
+//   map: [object SourceMapGenerator] }
+```

+ * A BasicSourceMapConsumer instance represents a parsed source map which we can
+ * query for information about the original file positions by giving it a file
+ * position in the generated source.
+ *
+ * The first parameter is the raw source map (either as a JSON string, or
+ * already parsed to an object). According to the spec, source maps have the
+ * following attributes:
+ *
+ *   - version: Which version of the source map spec this map is following.
+ *   - sources: An array of URLs to the original source files.
+ *   - names: An array of identifiers which can be referrenced by individual mappings.
+ *   - sourceRoot: Optional. The URL root from which all sources are relative.
+ *   - sourcesContent: Optional. An array of contents of the original source files.
+ *   - mappings: A string of base64 VLQs which contain the actual mappings.
+ *   - file: Optional. The generated file this source map is associated with.
+ *
+ * Here is an example source map, taken from the source map spec[0]:
+ *
+ *     {
+ *       version : 3,
+ *       file: "out.js",
+ *       sourceRoot : "",
+ *       sources: ["foo.js", "bar.js"],
+ *       names: ["src", "maps", "are", "fun"],
+ *       mappings: "AA,AB;;ABCDE;"
+ *     }
+ *
+ * The second parameter, if given, is a string whose value is the URL
+ * at which the source map was found.  This URL is used to compute the
+ * sources array.

+/**
+ * An IndexedSourceMapConsumer instance represents a parsed source map which
+ * we can query for information. It differs from BasicSourceMapConsumer in
+ * that it takes "indexed" source maps (i.e. ones with a "sections" field) as
+ * input.
+ *
+ * The first parameter is a raw source map (either as a JSON string, or already
+ * parsed to an object). According to the spec for indexed source maps, they
+ * have the following attributes:
+ *
+ *   - version: Which version of the source map spec this map is following.
+ *   - file: Optional. The generated file this source map is associated with.
+ *   - sections: A list of section definitions.
+ *
+ * Each value under the "sections" field has two fields:
+ *   - offset: The offset into the original specified at which this section
+ *       begins to apply, defined as an object with a "line" and "column"
+ *       field.
+ *   - map: A source map definition. This source map could also be indexed,
+ *       but doesn't have to be.
+ *
+ * Instead of the "map" field, it's also possible to have a "url" field
+ * specifying a URL to retrieve a source map from, but that's currently
+ * unsupported.
+ *
+ * Here's an example source map, taken from the source map spec[0], but
+ * modified to omit a section which uses the "url" field.
+ *
+ *  {
+ *    version : 3,
+ *    file: "app.js",
+ *    sections: [{
+ *      offset: {line:100, column:10},
+ *      map: {
+ *        version : 3,
+ *        file: "section.js",
+ *        sources: ["foo.js", "bar.js"],
+ *        names: ["src", "maps", "are", "fun"],
+ *        mappings: "AAAA,E;;ABCDE;"
+ *      }
+ *    }],
+ *  }
+ *
+ * The second parameter, if given, is a string whose value is the URL
+ * at which the source map was found.  This URL is used to compute the
+ * sources array.
+ *

-# Source Map
-
-This is a library to generate and consume the source map format
-[described here][format].
-
-This library is written in the Asynchronous Module Definition format, and works
-in the following environments:
-
-* Modern Browsers supporting ECMAScript 5 (either after the build, or with an
-  AMD loader such as RequireJS)
-
-* Inside Firefox (as a JSM file, after the build)
-
-* With NodeJS versions 0.8.X and higher
-
-## Node
-
-    $ npm install source-map
-
-## Building from Source (for everywhere else)
-
-Install Node and then run
-
-    $ git clone https://fitzgen@github.com/mozilla/source-map.git
-    $ cd source-map
-    $ npm link .
-
-Next, run
-
-    $ node Makefile.dryice.js
-
-This should spew a bunch of stuff to stdout, and create the following files:
-
-* `dist/source-map.js` - The unminified browser version.
-
-* `dist/source-map.min.js` - The minified browser version.
-
-* `dist/SourceMap.jsm` - The JavaScript Module for inclusion in Firefox source.
-
-## Examples
-
-### Consuming a source map
-
-```js
-var rawSourceMap = {
-  version: 3,
-  file: 'min.js',
-  names: ['bar', 'baz', 'n'],
-  sources: ['one.js', 'two.js'],
-  sourceRoot: 'http://example.com/www/js/',
-  mappings: 'CAAC,IAAI,IAAM,SAAUA,GAClB,OAAOC,IAAID;CCDb,IAAI,IAAM,SAAUE,GAClB,OAAOA'
-};
-
-var smc = new SourceMapConsumer(rawSourceMap);
-
-console.log(smc.sources);
-// [ 'http://example.com/www/js/one.js',
-//   'http://example.com/www/js/two.js' ]
-
-console.log(smc.originalPositionFor({
-  line: 2,
-  column: 28
-}));
-// { source: 'http://example.com/www/js/two.js',
-//   line: 2,
-//   column: 10,
-//   name: 'n' }
-
-console.log(smc.generatedPositionFor({
-  source: 'http://example.com/www/js/two.js',
-  line: 2,
-  column: 10
-}));
-// { line: 2, column: 28 }
-
-smc.eachMapping(function (m) {
-  // ...
-});
-```
-
-### Generating a source map
-
-In depth guide:
-[**Compiling to JavaScript, and Debugging with Source Maps**](https://hacks.mozilla.org/2013/05/compiling-to-javascript-and-debugging-with-source-maps/)
-
-#### With SourceNode (high level API)
-
-```js
-function compile(ast) {
-  switch (ast.type) {
-  case 'BinaryExpression':
-    return new SourceNode(
-      ast.location.line,
-      ast.location.column,
-      ast.location.source,
-      [compile(ast.left), " + ", compile(ast.right)]
-    );
-  case 'Literal':
-    return new SourceNode(
-      ast.location.line,
-      ast.location.column,
-      ast.location.source,
-      String(ast.value)
-    );
-  // ...
-  default:
-    throw new Error("Bad AST");
-  }
-}
-
-var ast = parse("40 + 2", "add.js");
-console.log(compile(ast).toStringWithSourceMap({
-  file: 'add.js'
-}));
-// { code: '40 + 2',
-//   map: [object SourceMapGenerator] }
-```
-
-#### With SourceMapGenerator (low level API)
-
-```js
-var map = new SourceMapGenerator({
-  file: "source-mapped.js"
-});
-
-map.addMapping({
-  generated: {
-    line: 10,
-    column: 35
-  },
-  source: "foo.js",
-  original: {
-    line: 33,
-    column: 2
-  },
-  name: "christopher"
-});
-
-console.log(map.toString());
-// '{"version":3,"file":"source-mapped.js","sources":["foo.js"],"names":["christopher"],"mappings":";;;;;;;;;mCAgCEA"}'
-```
-
-## API
-
-Get a reference to the module:
-
-```js
-// NodeJS
-var sourceMap = require('source-map');
-
-// Browser builds
-var sourceMap = window.sourceMap;
-
-// Inside Firefox
-let sourceMap = {};
-Components.utils.import('resource:///modules/devtools/SourceMap.jsm', sourceMap);
-```
-
-### SourceMapConsumer
-
-A SourceMapConsumer instance represents a parsed source map which we can query
-for information about the original file positions by giving it a file position
-in the generated source.
-
-#### new SourceMapConsumer(rawSourceMap)
-
-The only parameter is the raw source map (either as a string which can be
-`JSON.parse`'d, or an object). According to the spec, source maps have the
-following attributes:
-
-* `version`: Which version of the source map spec this map is following.
-
-* `sources`: An array of URLs to the original source files.
-
-* `names`: An array of identifiers which can be referrenced by individual
-  mappings.
-
-* `sourceRoot`: Optional. The URL root from which all sources are relative.
-
-* `sourcesContent`: Optional. An array of contents of the original source files.
-
-* `mappings`: A string of base64 VLQs which contain the actual mappings.
-
-* `file`: Optional. The generated filename this source map is associated with.
-
-#### SourceMapConsumer.prototype.computeColumnSpans()
-
-Compute the last column for each generated mapping. The last column is
-inclusive.
-
-#### SourceMapConsumer.prototype.originalPositionFor(generatedPosition)
-
-Returns the original source, line, and column information for the generated
-source's line and column positions provided. The only argument is an object with
-the following properties:
-
-* `line`: The line number in the generated source.
-
-* `column`: The column number in the generated source.
-
-* `bias`: Either `SourceMapConsumer.GREATEST_LOWER_BOUND` or
-  `SourceMapConsumer.LEAST_UPPER_BOUND`. Specifies whether to return the closest
-  element that is smaller than or greater than the one we are searching for,
-  respectively, if the exact element cannot be found.  Defaults to
-  `SourceMapConsumer.GREATEST_LOWER_BOUND`.
-
-and an object is returned with the following properties:
-
-* `source`: The original source file, or null if this information is not
-  available.
-
-* `line`: The line number in the original source, or null if this information is
-  not available.
-
-* `column`: The column number in the original source, or null or null if this
-  information is not available.
-
-* `name`: The original identifier, or null if this information is not available.
-
-#### SourceMapConsumer.prototype.generatedPositionFor(originalPosition)
-
-Returns the generated line and column information for the original source,
-line, and column positions provided. The only argument is an object with
-the following properties:
-
-* `source`: The filename of the original source.
-
-* `line`: The line number in the original source.
-
-* `column`: The column number in the original source.
-
-and an object is returned with the following properties:
-
-* `line`: The line number in the generated source, or null.
-
-* `column`: The column number in the generated source, or null.
-
-#### SourceMapConsumer.prototype.allGeneratedPositionsFor(originalPosition)
-
-Returns all generated line and column information for the original source, line,
-and column provided. If no column is provided, returns all mappings
-corresponding to a either the line we are searching for or the next closest line
-that has any mappings. Otherwise, returns all mappings corresponding to the
-given line and either the column we are searching for or the next closest column
-that has any offsets.
-
-The only argument is an object with the following properties:
-
-* `source`: The filename of the original source.
-
-* `line`: The line number in the original source.
-
-* `column`: Optional. The column number in the original source.
-
-and an array of objects is returned, each with the following properties:
-
-* `line`: The line number in the generated source, or null.
-
-* `column`: The column number in the generated source, or null.
-
-#### SourceMapConsumer.prototype.hasContentsOfAllSources()
-
-Return true if we have the embedded source content for every source listed in
-the source map, false otherwise.
-
-In other words, if this method returns `true`, then `smc.sourceContentFor(s)`
-will succeed for every source `s` in `smc.sources`.
-
-#### SourceMapConsumer.prototype.sourceContentFor(source[, returnNullOnMissing])
-
-Returns the original source content for the source provided. The only
-argument is the URL of the original source file.
-
-If the source content for the given source is not found, then an error is
-thrown. Optionally, pass `true` as the second param to have `null` returned
-instead.
-
-#### SourceMapConsumer.prototype.eachMapping(callback, context, order)
-
-Iterate over each mapping between an original source/line/column and a
-generated line/column in this source map.
-
-* `callback`: The function that is called with each mapping. Mappings have the
-  form `{ source, generatedLine, generatedColumn, originalLine, originalColumn,
-  name }`
-
-* `context`: Optional. If specified, this object will be the value of `this`
-  every time that `callback` is called.
-
-* `order`: Either `SourceMapConsumer.GENERATED_ORDER` or
-  `SourceMapConsumer.ORIGINAL_ORDER`. Specifies whether you want to iterate over
-  the mappings sorted by the generated file's line/column order or the
-  original's source/line/column order, respectively. Defaults to
-  `SourceMapConsumer.GENERATED_ORDER`.
-
-### SourceMapGenerator
-
-An instance of the SourceMapGenerator represents a source map which is being
-built incrementally.
-
-#### new SourceMapGenerator([startOfSourceMap])
-
-You may pass an object with the following properties:
-
-* `file`: The filename of the generated source that this source map is
-  associated with.
-
-* `sourceRoot`: A root for all relative URLs in this source map.
-
-* `skipValidation`: Optional. When `true`, disables validation of mappings as
-  they are added. This can improve performance but should be used with
-  discretion, as a last resort. Even then, one should avoid using this flag when
-  running tests, if possible.
-
-#### SourceMapGenerator.fromSourceMap(sourceMapConsumer)
-
-Creates a new SourceMapGenerator based on a SourceMapConsumer
-
-* `sourceMapConsumer` The SourceMap.
-
-#### SourceMapGenerator.prototype.addMapping(mapping)
-
-Add a single mapping from original source line and column to the generated
-source's line and column for this source map being created. The mapping object
-should have the following properties:
-
-* `generated`: An object with the generated line and column positions.
-
-* `original`: An object with the original line and column positions.
-
-* `source`: The original source file (relative to the sourceRoot).
-
-* `name`: An optional original token name for this mapping.
-
-#### SourceMapGenerator.prototype.setSourceContent(sourceFile, sourceContent)
-
-Set the source content for an original source file.
-
-* `sourceFile` the URL of the original source file.
-
-* `sourceContent` the content of the source file.
-
-#### SourceMapGenerator.prototype.applySourceMap(sourceMapConsumer[, sourceFile[, sourceMapPath]])
-
-Applies a SourceMap for a source file to the SourceMap.
-Each mapping to the supplied source file is rewritten using the
-supplied SourceMap. Note: The resolution for the resulting mappings
-is the minimium of this map and the supplied map.
-
-* `sourceMapConsumer`: The SourceMap to be applied.
-
-* `sourceFile`: Optional. The filename of the source file.
-  If omitted, sourceMapConsumer.file will be used, if it exists.
-  Otherwise an error will be thrown.
-
-* `sourceMapPath`: Optional. The dirname of the path to the SourceMap
-  to be applied. If relative, it is relative to the SourceMap.
-
-  This parameter is needed when the two SourceMaps aren't in the same
-  directory, and the SourceMap to be applied contains relative source
-  paths. If so, those relative source paths need to be rewritten
-  relative to the SourceMap.
-
-  If omitted, it is assumed that both SourceMaps are in the same directory,
-  thus not needing any rewriting. (Supplying `'.'` has the same effect.)
-
-#### SourceMapGenerator.prototype.toString()
-
-Renders the source map being generated to a string.
-
-### SourceNode
-
-SourceNodes provide a way to abstract over interpolating and/or concatenating
-snippets of generated JavaScript source code, while maintaining the line and
-column information associated between those snippets and the original source
-code. This is useful as the final intermediate representation a compiler might
-use before outputting the generated JS and source map.
-
-#### new SourceNode([line, column, source[, chunk[, name]]])
-
-* `line`: The original line number associated with this source node, or null if
-  it isn't associated with an original line.
-
-* `column`: The original column number associated with this source node, or null
-  if it isn't associated with an original column.
-
-* `source`: The original source's filename; null if no filename is provided.
-
-* `chunk`: Optional. Is immediately passed to `SourceNode.prototype.add`, see
-  below.
-
-* `name`: Optional. The original identifier.
-
-#### SourceNode.fromStringWithSourceMap(code, sourceMapConsumer[, relativePath])
-
-Creates a SourceNode from generated code and a SourceMapConsumer.
-
-* `code`: The generated code
-
-* `sourceMapConsumer` The SourceMap for the generated code
-
-* `relativePath` The optional path that relative sources in `sourceMapConsumer`
-  should be relative to.
-
-#### SourceNode.prototype.add(chunk)
-
-Add a chunk of generated JS to this source node.
-
-* `chunk`: A string snippet of generated JS code, another instance of
-   `SourceNode`, or an array where each member is one of those things.
-
-#### SourceNode.prototype.prepend(chunk)
-
-Prepend a chunk of generated JS to this source node.
-
-* `chunk`: A string snippet of generated JS code, another instance of
-   `SourceNode`, or an array where each member is one of those things.
-
-#### SourceNode.prototype.setSourceContent(sourceFile, sourceContent)
-
-Set the source content for a source file. This will be added to the
-`SourceMap` in the `sourcesContent` field.
-
-* `sourceFile`: The filename of the source file
-
-* `sourceContent`: The content of the source file
-
-#### SourceNode.prototype.walk(fn)
-
-Walk over the tree of JS snippets in this node and its children. The walking
-function is called once for each snippet of JS and is passed that snippet and
-the its original associated source's line/column location.
-
-* `fn`: The traversal function.
-
-#### SourceNode.prototype.walkSourceContents(fn)
-
-Walk over the tree of SourceNodes. The walking function is called for each
-source file content and is passed the filename and source content.
-
-* `fn`: The traversal function.
-
-#### SourceNode.prototype.join(sep)
-
-Like `Array.prototype.join` except for SourceNodes. Inserts the separator
-between each of this source node's children.
-
-* `sep`: The separator.
-
-#### SourceNode.prototype.replaceRight(pattern, replacement)
-
-Call `String.prototype.replace` on the very right-most source snippet. Useful
-for trimming whitespace from the end of a source node, etc.
-
-* `pattern`: The pattern to replace.
-
-* `replacement`: The thing to replace the pattern with.
-
-#### SourceNode.prototype.toString()
-
-Return the string representation of this source node. Walks over the tree and
-concatenates all the various snippets together to one string.
-
-#### SourceNode.prototype.toStringWithSourceMap([startOfSourceMap])
-
-Returns the string representation of this tree of source nodes, plus a
-SourceMapGenerator which contains all the mappings between the generated and
-original sources.
-
-The arguments are the same as those to `new SourceMapGenerator`.

-[![Build Status](https://travis-ci.org/mozilla/source-map.png?branch=master)](https://travis-ci.org/mozilla/source-map)
-
-Install NodeJS version 0.8.0 or greater, then run `node test/run-tests.js`.
-
-To add new tests, create a new file named `test/test-<your new test name>.js`
-and export your test functions with names that start with "test", for example
-
-```js
-exports["test doing the foo bar"] = function (assert, util) {
-  ...
-};
-```
-
-The new test will be located automatically when you run the suite.
-
-The `util` argument is the test utility module located at `test/source-map/util`.
-
-The `assert` argument is a cut down version of node's assert module. You have
-access to the following assertion functions:
-
-* `doesNotThrow`
-
-* `equal`
-
-* `ok`
-
-* `strictEqual`
-
-* `throws`
-
-(The reason for the restricted set of test functions is because we need the
-tests to run inside Firefox's test suite as well and so the assert module is
-shimmed in that environment. See `build/assert-shim.js`.)

-   * that it takes "indexed" source maps (i.e. ones with a "sections" field) as
-   * input.
-   *
-   * The only parameter is a raw source map (either as a JSON string, or already
-   * parsed to an object). According to the spec for indexed source maps, they
-   * have the following attributes:
-   *
-   *   - version: Which version of the source map spec this map is following.
-   *   - file: Optional. The generated file this source map is associated with.
-   *   - sections: A list of section definitions.
-   *
-   * Each value under the "sections" field has two fields:
-   *   - offset: The offset into the original specified at which this section
-   *       begins to apply, defined as an object with a "line" and "column"
-   *       field.
-   *   - map: A source map definition. This source map could also be indexed,
-   *       but doesn't have to be.
-   *
-   * Instead of the "map" field, it's also possible to have a "url" field
-   * specifying a URL to retrieve a source map from, but that's currently
-   * unsupported.
-   *
-   * Here's an example source map, taken from the source map spec[0], but
-   * modified to omit a section which uses the "url" field.
-   *
-   *  {
-   *    version : 3,
-   *    file: "app.js",
-   *    sections: [{
-   *      offset: {line:100, column:10},

-sshpk
-=========
-
-Parse, convert, fingerprint and use SSH keys (both public and private) in pure
-node -- no `ssh-keygen` or other external dependencies.
-
-Supports RSA, DSA, ECDSA (nistp-\*) and ED25519 key types, in PEM (PKCS#1, 
-PKCS#8) and OpenSSH formats.
-
-This library has been extracted from
-[`node-http-signature`](https://github.com/joyent/node-http-signature)
-(work by [Mark Cavage](https://github.com/mcavage) and
-[Dave Eddy](https://github.com/bahamas10)) and
-[`node-ssh-fingerprint`](https://github.com/bahamas10/node-ssh-fingerprint)
-(work by Dave Eddy), with additions (including ECDSA support) by
-[Alex Wilson](https://github.com/arekinath).
-
-Install
--------
-
-```
-npm install sshpk
-```
-
-Examples
---------
-
-```js
-var sshpk = require('sshpk');
-
-var fs = require('fs');
-
-/* Read in an OpenSSH-format public key */
-var keyPub = fs.readFileSync('id_rsa.pub');
-var key = sshpk.parseKey(keyPub, 'ssh');
-
-/* Get metadata about the key */
-console.log('type => %s', key.type);
-console.log('size => %d bits', key.size);
-console.log('comment => %s', key.comment);
-
-/* Compute key fingerprints, in new OpenSSH (>6.7) format, and old MD5 */
-console.log('fingerprint => %s', key.fingerprint().toString());
-console.log('old-style fingerprint => %s', key.fingerprint('md5').toString());
-```
-
-Example output:
-
-```
-type => rsa
-size => 2048 bits
-comment => foo@foo.com
-fingerprint => SHA256:PYC9kPVC6J873CSIbfp0LwYeczP/W4ffObNCuDJ1u5w
-old-style fingerprint => a0:c8:ad:6c:32:9a:32:fa:59:cc:a9:8c:0a:0d:6e:bd
-```
-
-More examples: converting between formats:
-
-```js
-/* Read in a PEM public key */
-var keyPem = fs.readFileSync('id_rsa.pem');
-var key = sshpk.parseKey(keyPem, 'pem');
-
-/* Convert to PEM PKCS#8 public key format */
-var pemBuf = key.toBuffer('pkcs8');
-
-/* Convert to SSH public key format (and return as a string) */
-var sshKey = key.toString('ssh');
-```
-
-Signing and verifying:
-
-```js
-/* Read in an OpenSSH/PEM *private* key */
-var keyPriv = fs.readFileSync('id_ecdsa');
-var key = sshpk.parsePrivateKey(keyPriv, 'pem');
-
-var data = 'some data';
-
-/* Sign some data with the key */
-var s = key.createSign('sha1');
-s.update(data);
-var signature = s.sign();
-
-/* Now load the public key (could also use just key.toPublic()) */
-var keyPub = fs.readFileSync('id_ecdsa.pub');
-key = sshpk.parseKey(keyPub, 'ssh');
-
-/* Make a crypto.Verifier with this key */
-var v = key.createVerify('sha1');
-v.update(data);
-var valid = v.verify(signature);
-/* => true! */
-```
-
-Matching fingerprints with keys:
-
-```js
-var fp = sshpk.parseFingerprint('SHA256:PYC9kPVC6J873CSIbfp0LwYeczP/W4ffObNCuDJ1u5w');
-
-var keys = [sshpk.parseKey(...), sshpk.parseKey(...), ...];
-
-keys.forEach(function (key) {
-	if (fp.matches(key))
-		console.log('found it!');
-});
-```
-
-Usage
------
-
-## Public keys
-
-### `parseKey(data[, format = 'auto'[, options]])`
-
-Parses a key from a given data format and returns a new `Key` object.
-
-Parameters
-
-- `data` -- Either a Buffer or String, containing the key
-- `format` -- String name of format to use, valid options are:
-  - `auto`: choose automatically from all below
-  - `pem`: supports both PKCS#1 and PKCS#8
-  - `ssh`: standard OpenSSH format,
-  - `pkcs1`, `pkcs8`: variants of `pem`
-  - `rfc4253`: raw OpenSSH wire format
-  - `openssh`: new post-OpenSSH 6.5 internal format, produced by 
-               `ssh-keygen -o`
-  - `dnssec`: `.key` file format output by `dnssec-keygen` etc
-  - `putty`: the PuTTY `.ppk` file format (supports truncated variant without
-             all the lines from `Private-Lines:` onwards)
-- `options` -- Optional Object, extra options, with keys:
-  - `filename` -- Optional String, name for the key being parsed 
-                  (eg. the filename that was opened). Used to generate
-                  Error messages
-  - `passphrase` -- Optional String, encryption passphrase used to decrypt an
-                    encrypted PEM file
-
-### `Key.isKey(obj)`
-
-Returns `true` if the given object is a valid `Key` object created by a version
-of `sshpk` compatible with this one.
-
-Parameters
-
-- `obj` -- Object to identify
-
-### `Key#type`
-
-String, the type of key. Valid options are `rsa`, `dsa`, `ecdsa`.
-
-### `Key#size`
-
-Integer, "size" of the key in bits. For RSA/DSA this is the size of the modulus;
-for ECDSA this is the bit size of the curve in use.
-
-### `Key#comment`
-
-Optional string, a key comment used by some formats (eg the `ssh` format).
-
-### `Key#curve`
-
-Only present if `this.type === 'ecdsa'`, string containing the name of the
-named curve used with this key. Possible values include `nistp256`, `nistp384`
-and `nistp521`.
-
-### `Key#toBuffer([format = 'ssh'])`
-
-Convert the key into a given data format and return the serialized key as
-a Buffer.
-
-Parameters
-
-- `format` -- String name of format to use, for valid options see `parseKey()`
-
-### `Key#toString([format = 'ssh])`
-
-Same as `this.toBuffer(format).toString()`.
-
-### `Key#fingerprint([algorithm = 'sha256'[, hashType = 'ssh']])`
-
-Creates a new `Fingerprint` object representing this Key's fingerprint.
-
-Parameters
-
-- `algorithm` -- String name of hash algorithm to use, valid options are `md5`,
-                 `sha1`, `sha256`, `sha384`, `sha512`
-- `hashType` -- String name of fingerprint hash type to use, valid options are
-                `ssh` (the type of fingerprint used by OpenSSH, e.g. in
-                `ssh-keygen`), `spki` (used by HPKP, some OpenSSL applications)
-
-### `Key#createVerify([hashAlgorithm])`
-
-Creates a `crypto.Verifier` specialized to use this Key (and the correct public
-key algorithm to match it). The returned Verifier has the same API as a regular
-one, except that the `verify()` function takes only the target signature as an
-argument.
-
-Parameters
-
-- `hashAlgorithm` -- optional String name of hash algorithm to use, any
-                     supported by OpenSSL are valid, usually including
-                     `sha1`, `sha256`.
-
-`v.verify(signature[, format])` Parameters
-
-- `signature` -- either a Signature object, or a Buffer or String
-- `format` -- optional String, name of format to interpret given String with.
-              Not valid if `signature` is a Signature or Buffer.
-
-### `Key#createDiffieHellman()`
-### `Key#createDH()`
-
-Creates a Diffie-Hellman key exchange object initialized with this key and all
-necessary parameters. This has the same API as a `crypto.DiffieHellman`
-instance, except that functions take `Key` and `PrivateKey` objects as
-arguments, and return them where indicated for.
-
-This is only valid for keys belonging to a cryptosystem that supports DHE
-or a close analogue (i.e. `dsa`, `ecdsa` and `curve25519` keys). An attempt
-to call this function on other keys will yield an `Error`.
-
-## Private keys
-

-              format instead (as they have no `pkcs1` representation).
-
-### `PrivateKey#toString([format = 'pkcs1'])`
-
-Same as `this.toBuffer(format).toString()`.
-
-### `PrivateKey#toPublic()`
-
-Extract just the public part of this private key, and return it as a `Key`
-object.
-
-### `PrivateKey#fingerprint([algorithm = 'sha256'])`
-
-Same as `this.toPublic().fingerprint()`.
-
-### `PrivateKey#createVerify([hashAlgorithm])`
-
-Same as `this.toPublic().createVerify()`.
-
-### `PrivateKey#createSign([hashAlgorithm])`
-
-Creates a `crypto.Sign` specialized to use this PrivateKey (and the correct
-key algorithm to match it). The returned Signer has the same API as a regular
-one, except that the `sign()` function takes no arguments, and returns a
-`Signature` object.
-
-Parameters
-
-- `hashAlgorithm` -- optional String name of hash algorithm to use, any
-                     supported by OpenSSL are valid, usually including
-                     `sha1`, `sha256`.
-
-`v.sign()` Parameters
-
-- none
-
-### `PrivateKey#derive(newType)`
-
-Derives a related key of type `newType` from this key. Currently this is
-only supported to change between `ed25519` and `curve25519` keys which are
-stored with the same private key (but usually distinct public keys in order
-to avoid degenerate keys that lead to a weak Diffie-Hellman exchange).
-
-Parameters
-
-- `newType` -- String, type of key to derive, either `ed25519` or `curve25519`
-
-## Fingerprints
-
-### `parseFingerprint(fingerprint[, options])`
-
-Pre-parses a fingerprint, creating a `Fingerprint` object that can be used to
-quickly locate a key by using the `Fingerprint#matches` function.
-
-Parameters
-
-- `fingerprint` -- String, the fingerprint value, in any supported format
-- `options` -- Optional Object, with properties:
-  - `algorithms` -- Array of strings, names of hash algorithms to limit
-                support to. If `fingerprint` uses a hash algorithm not on
-                this list, throws `InvalidAlgorithmError`.
-  - `hashType` -- String, the type of hash the fingerprint uses, either `ssh`
-                  or `spki` (normally auto-detected based on the format, but
-                  can be overridden)
-  - `type` -- String, the entity this fingerprint identifies, either `key` or
-              `certificate`
-
-### `Fingerprint.isFingerprint(obj)`
-
-Returns `true` if the given object is a valid `Fingerprint` object created by a
-version of `sshpk` compatible with this one.
-
-Parameters
-
-- `obj` -- Object to identify
-
-### `Fingerprint#toString([format])`
-
-Returns a fingerprint as a string, in the given format.
-
-Parameters
-
-- `format` -- Optional String, format to use, valid options are `hex` and
-              `base64`. If this `Fingerprint` uses the `md5` algorithm, the
-              default format is `hex`. Otherwise, the default is `base64`.
-
-### `Fingerprint#matches(keyOrCertificate)`
-
-Verifies whether or not this `Fingerprint` matches a given `Key` or
-`Certificate`. This function uses double-hashing to avoid leaking timing
-information. Returns a boolean.
-
-Note that a `Key`-type Fingerprint will always return `false` if asked to match
-a `Certificate` and vice versa.
-
-Parameters
-
-- `keyOrCertificate` -- a `Key` object or `Certificate` object, the entity to
-                        match this fingerprint against
-
-## Signatures
-
-### `parseSignature(signature, algorithm, format)`
-
-Parses a signature in a given format, creating a `Signature` object. Useful
-for converting between the SSH and ASN.1 (PKCS/OpenSSL) signature formats, and
-also returned as output from `PrivateKey#createSign().sign()`.
-
-A Signature object can also be passed to a verifier produced by
-`Key#createVerify()` and it will automatically be converted internally into the
-correct format for verification.
-
-Parameters
-
-- `signature` -- a Buffer (binary) or String (base64), data of the actual
-                 signature in the given format
-- `algorithm` -- a String, name of the algorithm to be used, possible values
-                 are `rsa`, `dsa`, `ecdsa`
-- `format` -- a String, either `asn1` or `ssh`
-
-### `Signature.isSignature(obj)`
-
-Returns `true` if the given object is a valid `Signature` object created by a
-version of `sshpk` compatible with this one.
-
-Parameters
-
-- `obj` -- Object to identify
-
-### `Signature#toBuffer([format = 'asn1'])`
-
-Converts a Signature to the given format and returns it as a Buffer.
-
-Parameters
-
-- `format` -- a String, either `asn1` or `ssh`
-
-### `Signature#toString([format = 'asn1'])`
-
-Same as `this.toBuffer(format).toString('base64')`.
-
-## Certificates
-
-`sshpk` includes basic support for parsing certificates in X.509 (PEM) format
-and the OpenSSH certificate format. This feature is intended to be used mainly
-to access basic metadata about certificates, extract public keys from them, and
-also to generate simple self-signed certificates from an existing key.
-
-Notably, there is no implementation of CA chain-of-trust verification, and only
-very minimal support for key usage restrictions. Please do the security world
-a favour, and DO NOT use this code for certificate verification in the
-traditional X.509 CA chain style.
-
-### `parseCertificate(data, format)`
-
-Parameters
-
- - `data` -- a Buffer or String
- - `format` -- a String, format to use, one of `'openssh'`, `'pem'` (X.509 in a

-.RE
-.SH OPTIONS
-.TP
-\fB\fC\-i, \-\-identify\fR
-Instead of converting the key, output identifying information about it to 
-stderr, including its type, size and fingerprints.
-.TP
-\fB\fC\-p, \-\-private\fR
-Treat the key as a private key instead of a public key (the default). If you
-supply \fB\fCsshpk\-conv\fR with a private key and do not give this option, it will
-extract only the public half of the key from it and work with that.
-.TP
-\fB\fC\-f PATH, \-\-file=PATH\fR
-Input file to take the key from instead of stdin. If a filename is supplied
-as a positional argument, it is equivalent to using this option.
-.TP
-\fB\fC\-o PATH, \-\-out=PATH\fR
-Output file name to use instead of stdout.
-.PP
-\fB\fC\-T FORMAT, \-\-informat=FORMAT\fR
-.TP
-\fB\fC\-t FORMAT, \-\-outformat=FORMAT\fR
-Selects the input and output formats to be used (see FORMATS, below).
-.TP
-\fB\fC\-c TEXT, \-\-comment=TEXT\fR
-Sets the key comment for the output file, if supported.
-.SH FORMATS
-.PP
-Currently supported formats:
-.TP
-\fB\fCpem, pkcs1\fR
-The standard PEM format used by older OpenSSH and most TLS libraries such as
-OpenSSL. The classic \fB\fCid_rsa\fR file is usually in this format. It is an ASN.1
-encoded structure, base64\-encoded and placed between PEM headers.
-.TP
-\fB\fCssh\fR
-The SSH public key text format (the format of an \fB\fCid_rsa.pub\fR file). A single
-line, containing 3 space separated parts: the key type, key body and optional
-key comment.
-.TP
-\fB\fCpkcs8\fR
-A newer PEM format, usually used only for public keys by TLS libraries such
-as OpenSSL. The ASN.1 structure is more generic than that of \fB\fCpkcs1\fR\&.
-.TP
-\fB\fCopenssh\fR
-The new \fB\fCssh\-keygen \-o\fR format from OpenSSH. This can be mistaken for a PEM
-encoding but is actually an OpenSSH internal format.
-.TP
-\fB\fCrfc4253\fR
-The internal binary format of keys when sent over the wire in the SSH
-protocol. This is also the format that the \fB\fCssh\-agent\fR uses in its protocol.
-.SH SEE ALSO

-## Rant
-
-Try saving this example as `example.js`
-
-``` js
-console.error('start');
-process.stdout.write(new Buffer(1024*1024));
-console.error('end');
-```
-
-And run the following program
-
-```
-node example.js | sleep 1000
-```
-
-The program will never print `end` since stdout in node currently is blocking - even when its being piped (!).
-
-stdout-stream tries to fix this by being a stream that writes to stdout but never blocks
-
-## Usage
-
-``` js
-var stdout = require('stdout-stream');
-
-stdout.write('hello\n'); // write should NEVER block
-stdout.write('non-blocking\n')
-stdout.write('world\n');
-```
-
-`stdout-stream` should behave in the same way as `process.stdout` (i.e. do not end on pipe etc)

-### Streams Working Group
-
-The Node.js Streams is jointly governed by a Working Group
-(WG)
-that is responsible for high-level guidance of the project.
-
-The WG has final authority over this project including:
-
-* Technical direction
-* Project governance and process (including this policy)
-* Contribution policy
-* GitHub repository hosting
-* Conduct guidelines
-* Maintaining the list of additional Collaborators
-
-For the current list of WG members, see the project
-[README.md](./README.md#current-project-team-members).
-
-### Collaborators
-
-The readable-stream GitHub repository is
-maintained by the WG and additional Collaborators who are added by the
-WG on an ongoing basis.
-
-Individuals making significant and valuable contributions are made
-Collaborators and given commit-access to the project. These
-individuals are identified by the WG and their addition as
-Collaborators is discussed during the WG meeting.
-
-_Note:_ If you make a significant contribution and are not considered
-for commit-access log an issue or contact a WG member directly and it
-will be brought up in the next WG meeting.
-
-Modifications of the contents of the readable-stream repository are
-made on
-a collaborative basis. Anybody with a GitHub account may propose a
-modification via pull request and it will be considered by the project
-Collaborators. All pull requests must be reviewed and accepted by a
-Collaborator with sufficient expertise who is able to take full
-responsibility for the change. In the case of pull requests proposed
-by an existing Collaborator, an additional Collaborator is required
-for sign-off. Consensus should be sought if additional Collaborators
-participate and there is disagreement around a particular
-modification. See _Consensus Seeking Process_ below for further detail
-on the consensus model used for governance.
-
-Collaborators may opt to elevate significant or controversial
-modifications, or modifications that have not found consensus to the
-WG for discussion by assigning the ***WG-agenda*** tag to a pull
-request or issue. The WG should serve as the final arbiter where
-required.
-
-For the current list of Collaborators, see the project
-[README.md](./README.md#members).
-
-### WG Membership
-
-WG seats are not time-limited.  There is no fixed size of the WG.
-However, the expected target is between 6 and 12, to ensure adequate
-coverage of important areas of expertise, balanced with the ability to
-make decisions efficiently.
-
-There is no specific set of requirements or qualifications for WG
-membership beyond these rules.
-
-The WG may add additional members to the WG by unanimous consensus.
-
-A WG member may be removed from the WG by voluntary resignation, or by
-unanimous consensus of all other WG members.
-
-Changes to WG membership should be posted in the agenda, and may be
-suggested as any other agenda item (see "WG Meetings" below).
-
-If an addition or removal is proposed during a meeting, and the full
-WG is not in attendance to participate, then the addition or removal
-is added to the agenda for the subsequent meeting.  This is to ensure
-that all members are given the opportunity to participate in all
-membership decisions.  If a WG member is unable to attend a meeting
-where a planned membership decision is being made, then their consent
-is assumed.
-
-No more than 1/3 of the WG members may be affiliated with the same
-employer.  If removal or resignation of a WG member, or a change of
-employment by a WG member, creates a situation where more than 1/3 of
-the WG membership shares an employer, then the situation must be
-immediately remedied by the resignation or removal of one or more WG
-members affiliated with the over-represented employer(s).
-
-### WG Meetings
-
-The WG meets occasionally on a Google Hangout On Air. A designated moderator
-approved by the WG runs the meeting. Each meeting should be
-published to YouTube.
-
-Items are added to the WG agenda that are considered contentious or
-are modifications of governance, contribution policy, WG membership,
-or release process.
-
-The intention of the agenda is not to approve or review all patches;
-that should happen continuously on GitHub and be handled by the larger
-group of Collaborators.
-
-Any community member or contributor can ask that something be added to
-the next meeting's agenda by logging a GitHub Issue. Any Collaborator,
-WG member or the moderator can add the item to the agenda by adding
-the ***WG-agenda*** tag to the issue.
-
-Prior to each WG meeting the moderator will share the Agenda with
-members of the WG. WG members can add any items they like to the
-agenda at the beginning of each meeting. The moderator and the WG
-cannot veto or remove items.
-
-The WG may invite persons or representatives from certain projects to
-participate in a non-voting capacity.
-
-The moderator is responsible for summarizing the discussion of each
-agenda item and sends it as a pull request after the meeting.
-
-### Consensus Seeking Process
-
-The WG follows a
-[Consensus
-Seeking](http://en.wikipedia.org/wiki/Consensus-seeking_decision-making)
-decision-making model.
-
-When an agenda item has appeared to reach a consensus the moderator
-will ask "Does anyone object?" as a final call for dissent from the
-consensus.
-
-If an agenda item cannot reach a consensus a WG member can call for
-either a closing vote or a vote to table the issue to the next
-meeting. The call for a vote must be seconded by a majority of the WG
-or else the discussion will continue. Simple majority wins.
-
-Note that changes to WG membership require a majority consensus.  See
-"WG Membership" above.

-***Node-core streams for userland***
-
-This package is a mirror of the Streams2 and Streams3 implementations in

-Full documentation may be found on the [Node.js website](https://nodejs.org/dist/v8.11.1/docs/api/stream.html).
-
-If you want to guarantee a stable streams base, regardless of what version of

-
-As of version 2.0.0 **readable-stream** uses semantic versioning.

-# Streams Working Group
-
-`readable-stream` is maintained by the Streams Working Group, which
-oversees the development and maintenance of the Streams API within
-Node.js. The responsibilities of the Streams Working Group include:
-
-* Addressing stream issues on the Node.js issue tracker.
-* Authoring and editing stream documentation within the Node.js project.
-* Reviewing changes to stream subclasses within the Node.js project.
-* Redirecting changes to streams from the Node.js project to this
-  project.
-* Assisting in the implementation of stream providers within Node.js.
-* Recommending versions of `readable-stream` to be included in Node.js.
-* Messaging about the future of streams to give the community advance
-  notice of changes.

-## Agenda
-
-Extracted from https://github.com/iojs/readable-stream/labels/wg-agenda prior to meeting.
-
-* adopt a charter [#105](https://github.com/iojs/readable-stream/issues/105)
-* release and versioning strategy [#101](https://github.com/iojs/readable-stream/issues/101)

-* proposal: deprecate implicit flowing of streams [#99](https://github.com/iojs/readable-stream/issues/99)
-
-## Minutes
-
-### adopt a charter
-
-* group: +1's all around
-
-### What versioning scheme should be adopted?
-* group: +1’s 3.0.0
-* domenic+group: pulling in patches from other sources where appropriate
-* mikeal: version independently, suggesting versions for io.js
-* mikeal+domenic: work with TC to notify in advance of changes
-simpler stream creation
-
-### streamline creation of streams
-* sam: streamline creation of streams
-* domenic: nice simple solution posted
-  but, we lose the opportunity to change the model
-  may not be backwards incompatible (double check keys)
-
-  **action item:** domenic will check
-
-### remove implicit flowing of streams on(‘data’)
-* add isFlowing / isPaused
-* mikeal: worrying that we’re documenting polyfill methods – confuses users
-* domenic: more reflective API is probably good, with warning labels for users
-* new section for mad scientists (reflective stream access)
-* calvin: name the “third state”
-* mikeal: maybe borrow the name from whatwg?
-* domenic: we’re missing the “third state”
-* consensus: kind of difficult to name the third state
-* mikeal: figure out differences in states / compat
-* mathias: always flow on data – eliminates third state
-  * explore what it breaks
-
-**action items:**
-* ask isaac for ability to list packages by what public io.js APIs they use (esp. Stream)
-* ask rod/build for infrastructure
-* **chris**: explore the “flow on data” approach
-* add isPaused/isFlowing
-* add new docs section
-* move isPaused to that section
-

-// a transform stream is a readable/writable stream where you do
-// something with the data.  Sometimes it's called a "filter",
-// but that's not a great name for it, since that implies a thing where
-// some bits pass through, and others are simply ignored.  (That would
-// be a valid example of a transform, of course.)
-//
-// While the output is causally related to the input, it's not a
-// necessarily symmetric or synchronous transformation.  For example,
-// a zlib stream might take multiple plain-text writes(), and then
-// emit a single compressed chunk some time in the future.
-//
-// Here's how this works:
-//
-// The Transform stream has all the aspects of the readable and writable
-// stream classes.  When you write(chunk), that calls _write(chunk,cb)
-// internally, and returns false if there's a lot of pending writes
-// buffered up.  When you call read(), that calls _read(n) until
-// there's enough pending readable data buffered up.
-//
-// In a transform stream, the written data is placed in a buffer.  When
-// _read(n) is called, it transforms the queued up data, calling the
-// buffered _write cb's as it consumes chunks.  If consuming a single
-// written chunk would result in multiple output chunks, then the first
-// outputted bit calls the readcb, and subsequent chunks just go into
-// the read buffer, and will cause it to emit 'readable' if necessary.
-//
-// This way, back-pressure is actually determined by the reading side,
-// since _read has to be called to start processing a new chunk.  However,
-// a pathological inflate type of transform can cause excessive buffering
-// here.  For example, imagine a stream where every byte of input is
-// interpreted as an integer from 0-255, and then results in that many
-// bytes of output.  Writing the 4 bytes {ff,ff,ff,ff} would result in
-// 1kb of data being output.  In this case, you could write a very small
-// amount of input, and end up with a very large amount of output.  In
-// such a pathological inflating mechanism, there'd be no way to tell
-// the system to stop doing the transform.  A single 4MB write could
-// cause the system to run out of memory.
-//
-// However, even in such a pathological case, only a single written chunk
-// would be consumed, and then the rest would wait (un-transformed) until
-// the results of the previous transformed chunk were consumed.

-
-

-[![NPM](https://nodei.co/npm-dl/string_decoder.png?&months=6&height=3)](https://nodei.co/npm/string_decoder/)
-
-
-```bash
-npm install --save string_decoder
-```
-
-***Node-core string_decoder for userland***
-
-This package is a mirror of the string_decoder implementation in Node-core.
-
-Full documentation may be found on the [Node.js website](https://nodejs.org/dist/v8.9.4/docs/api/).
-
-As of version 1.0.0 **string_decoder** uses semantic versioning.
-
-## Previous versions
-
-Previous version numbers match the versions found in Node core, e.g. 0.10.24 matches Node 0.10.24, likewise 0.11.10 matches Node 0.11.10.
-
-## Update
-
-The *build/* directory contains a build script that will scrape the source from the [nodejs/node](https://github.com/nodejs/node) repo given a specific Node version.
-
-## Streams Working Group
-
-`string_decoder` is maintained by the Streams Working Group, which
-oversees the development and maintenance of the Streams API within
-Node.js. The responsibilities of the Streams Working Group include:
-
-* Addressing stream issues on the Node.js issue tracker.
-* Authoring and editing stream documentation within the Node.js project.
-* Reviewing changes to stream subclasses within the Node.js project.
-* Redirecting changes to streams from the Node.js project to this
-  project.
-* Assisting in the implementation of stream providers within Node.js.
-* Recommending versions of `readable-stream` to be included in Node.js.
-* Messaging about the future of streams to give the community advance
-  notice of changes.
-
-See [readable-stream](https://github.com/nodejs/readable-stream) for
-more details.

-> Detect whether a terminal supports color
-
-
-## Install
-
-```
-$ npm install --save supports-color
-```
-
-
-## Usage
-
-```js
-var supportsColor = require('supports-color');
-
-if (supportsColor) {
-	console.log('Terminal supports color');
-}
-```
-
-It obeys the `--color` and `--no-color` CLI flags.
-
-For situations where using `--color` is not possible, add an environment variable `FORCE_COLOR` with any value to force color. Trumps `--no-color`.

-# node-tar
-
-Tar for Node.js.
-
-[![NPM](https://nodei.co/npm/tar.png)](https://nodei.co/npm/tar/)
-
-## API
-
-See `examples/` for usage examples.
-
-### var tar = require('tar')
-
-Returns an object with `.Pack`, `.Extract` and `.Parse` methods.
-
-### tar.Pack([properties])
-
-Returns a through stream. Use
-[fstream](https://npmjs.org/package/fstream) to write files into the
-pack stream and you will receive tar archive data from the pack
-stream.
-
-This only works with directories, it does not work with individual files.
-
-The optional `properties` object are used to set properties in the tar
-'Global Extended Header'. If the `fromBase` property is set to true,
-the tar will contain files relative to the path passed, and not with
-the path included.
-
-### tar.Extract([options])
-
-Returns a through stream. Write tar data to the stream and the files
-in the tarball will be extracted onto the filesystem.
-
-`options` can be:
-
-```js
-{
-  path: '/path/to/extract/tar/into',
-  strip: 0, // how many path segments to strip from the root when extracting
-}
-```
-
-`options` also get passed to the `fstream.Writer` instance that `tar`
-uses internally.
-
-### tar.Parse()
-
-Returns a writable stream. Write tar data to it and it will emit
-`entry` events for each entry parsed from the tarball. This is used by
-`tar.Extract`.

-[RFC6265](https://tools.ietf.org/html/rfc6265) Cookies and CookieJar for Node.js
-
-[![npm package](https://nodei.co/npm/tough-cookie.png?downloads=true&downloadRank=true&stars=true)](https://nodei.co/npm/tough-cookie/)
-
-[![Build Status](https://travis-ci.org/salesforce/tough-cookie.png?branch=master)](https://travis-ci.org/salesforce/tough-cookie)
-
-# Synopsis
-
-``` javascript
-var tough = require('tough-cookie');
-var Cookie = tough.Cookie;
-var cookie = Cookie.parse(header);
-cookie.value = 'somethingdifferent';
-header = cookie.toString();
-
-var cookiejar = new tough.CookieJar();
-cookiejar.setCookie(cookie, 'http://currentdomain.example.com/path', cb);
-// ...
-cookiejar.getCookies('http://example.com/otherpath',function(err,cookies) {
-  res.headers['cookie'] = cookies.join('; ');
-});
-```
-
-# Installation
-
-It's _so_ easy!
-
-`npm install tough-cookie`
-
-Why the name?  NPM modules `cookie`, `cookies` and `cookiejar` were already taken.
-
-## Version Support
-
-Support for versions of node.js will follow that of the [request](https://www.npmjs.com/package/request) module.
-
-# API
-
-## tough
-
-Functions on the module you get from `require('tough-cookie')`.  All can be used as pure functions and don't need to be "bound".
-
-**Note**: prior to 1.0.x, several of these functions took a `strict` parameter. This has since been removed from the API as it was no longer necessary.
-
-### `parseDate(string)`
-
-Parse a cookie date string into a `Date`.  Parses according to RFC6265 Section 5.1.1, not `Date.parse()`.
-
-### `formatDate(date)`
-
-Format a Date into a RFC1123 string (the RFC6265-recommended format).
-
-### `canonicalDomain(str)`
-
-Transforms a domain-name into a canonical domain-name.  The canonical domain-name is a trimmed, lowercased, stripped-of-leading-dot and optionally punycode-encoded domain-name (Section 5.1.2 of RFC6265).  For the most part, this function is idempotent (can be run again on its output without ill effects).
-
-### `domainMatch(str,domStr[,canonicalize=true])`
-
-Answers "does this real domain match the domain in a cookie?".  The `str` is the "current" domain-name and the `domStr` is the "cookie" domain-name.  Matches according to RFC6265 Section 5.1.3, but it helps to think of it as a "suffix match".
-
-The `canonicalize` parameter will run the other two parameters through `canonicalDomain` or not.
-
-### `defaultPath(path)`
-
-Given a current request/response path, gives the Path apropriate for storing in a cookie.  This is basically the "directory" of a "file" in the path, but is specified by Section 5.1.4 of the RFC.
-
-The `path` parameter MUST be _only_ the pathname part of a URI (i.e. excludes the hostname, query, fragment, etc.).  This is the `.pathname` property of node's `uri.parse()` output.
-
-### `pathMatch(reqPath,cookiePath)`
-
-Answers "does the request-path path-match a given cookie-path?" as per RFC6265 Section 5.1.4.  Returns a boolean.
-
-This is essentially a prefix-match where `cookiePath` is a prefix of `reqPath`.
-
-### `parse(cookieString[, options])`
-
-alias for `Cookie.parse(cookieString[, options])`
-
-### `fromJSON(string)`
-
-alias for `Cookie.fromJSON(string)`
-
-### `getPublicSuffix(hostname)`
-
-Returns the public suffix of this hostname.  The public suffix is the shortest domain-name upon which a cookie can be set.  Returns `null` if the hostname cannot have cookies set for it.
-
-For example: `www.example.com` and `www.subdomain.example.com` both have public suffix `example.com`.
-
-For further information, see http://publicsuffix.org/.  This module derives its list from that site. This call is currently a wrapper around [`psl`](https://www.npmjs.com/package/psl)'s [get() method](https://www.npmjs.com/package/psl#pslgetdomain).
-
-### `cookieCompare(a,b)`
-
-For use with `.sort()`, sorts a list of cookies into the recommended order given in the RFC (Section 5.4 step 2). The sort algorithm is, in order of precedence:
-
-* Longest `.path`
-* oldest `.creation` (which has a 1ms precision, same as `Date`)
-* lowest `.creationIndex` (to get beyond the 1ms precision)
-
-``` javascript
-var cookies = [ /* unsorted array of Cookie objects */ ];
-cookies = cookies.sort(cookieCompare);
-```
-
-**Note**: Since JavaScript's `Date` is limited to a 1ms precision, cookies within the same milisecond are entirely possible. This is especially true when using the `now` option to `.setCookie()`. The `.creationIndex` property is a per-process global counter, assigned during construction with `new Cookie()`. This preserves the spirit of the RFC sorting: older cookies go first. This works great for `MemoryCookieStore`, since `Set-Cookie` headers are parsed in order, but may not be so great for distributed systems. Sophisticated `Store`s may wish to set this to some other _logical clock_ such that if cookies A and B are created in the same millisecond, but cookie A is created before cookie B, then `A.creationIndex < B.creationIndex`. If you want to alter the global counter, which you probably _shouldn't_ do, it's stored in `Cookie.cookiesCreated`.
-
-### `permuteDomain(domain)`
-
-Generates a list of all possible domains that `domainMatch()` the parameter.  May be handy for implementing cookie stores.
-
-### `permutePath(path)`
-
-Generates a list of all possible paths that `pathMatch()` the parameter.  May be handy for implementing cookie stores.
-
-
-## Cookie
-
-Exported via `tough.Cookie`.
-
-### `Cookie.parse(cookieString[, options])`
-
-Parses a single Cookie or Set-Cookie HTTP header into a `Cookie` object.  Returns `undefined` if the string can't be parsed.
-
-The options parameter is not required and currently has only one property:
-
-  * _loose_ - boolean - if `true` enable parsing of key-less cookies like `=abc` and `=`, which are not RFC-compliant.
-
-If options is not an object, it is ignored, which means you can use `Array#map` with it.
-
-Here's how to process the Set-Cookie header(s) on a node HTTP/HTTPS response:
-
-``` javascript
-if (res.headers['set-cookie'] instanceof Array)
-  cookies = res.headers['set-cookie'].map(Cookie.parse);
-else
-  cookies = [Cookie.parse(res.headers['set-cookie'])];
-```
-
-_Note:_ in version 2.3.3, tough-cookie limited the number of spaces before the `=` to 256 characters. This limitation has since been removed.
-See [Issue 92](https://github.com/salesforce/tough-cookie/issues/92)
-
-### Properties
-
-Cookie object properties:
-
-  * _key_ - string - the name or key of the cookie (default "")
-  * _value_ - string - the value of the cookie (default "")
-  * _expires_ - `Date` - if set, the `Expires=` attribute of the cookie (defaults to the string `"Infinity"`). See `setExpires()`
-  * _maxAge_ - seconds - if set, the `Max-Age=` attribute _in seconds_ of the cookie.  May also be set to strings `"Infinity"` and `"-Infinity"` for non-expiry and immediate-expiry, respectively.  See `setMaxAge()`
-  * _domain_ - string - the `Domain=` attribute of the cookie
-  * _path_ - string - the `Path=` of the cookie
-  * _secure_ - boolean - the `Secure` cookie flag
-  * _httpOnly_ - boolean - the `HttpOnly` cookie flag
-  * _extensions_ - `Array` - any unrecognized cookie attributes as strings (even if equal-signs inside)
-  * _creation_ - `Date` - when this cookie was constructed
-  * _creationIndex_ - number - set at construction, used to provide greater sort precision (please see `cookieCompare(a,b)` for a full explanation)
-
-After a cookie has been passed through `CookieJar.setCookie()` it will have the following additional attributes:
-
-  * _hostOnly_ - boolean - is this a host-only cookie (i.e. no Domain field was set, but was instead implied)
-  * _pathIsDefault_ - boolean - if true, there was no Path field on the cookie and `defaultPath()` was used to derive one.
-  * _creation_ - `Date` - **modified** from construction to when the cookie was added to the jar
-  * _lastAccessed_ - `Date` - last time the cookie got accessed. Will affect cookie cleaning once implemented.  Using `cookiejar.getCookies(...)` will update this attribute.
-
-### `Cookie([{properties}])`
-
-Receives an options object that can contain any of the above Cookie properties, uses the default for unspecified properties.
-
-### `.toString()`
-
-encode to a Set-Cookie header value.  The Expires cookie field is set using `formatDate()`, but is omitted entirely if `.expires` is `Infinity`.
-
-### `.cookieString()`
-
-encode to a Cookie header value (i.e. the `.key` and `.value` properties joined with '=').
-
-### `.setExpires(String)`
-
-sets the expiry based on a date-string passed through `parseDate()`.  If parseDate returns `null` (i.e. can't parse this date string), `.expires` is set to `"Infinity"` (a string) is set.
-
-### `.setMaxAge(number)`
-
-sets the maxAge in seconds.  Coerces `-Infinity` to `"-Infinity"` and `Infinity` to `"Infinity"` so it JSON serializes correctly.
-
-### `.expiryTime([now=Date.now()])`
-
-### `.expiryDate([now=Date.now()])`
-
-expiryTime() Computes the absolute unix-epoch milliseconds that this cookie expires. expiryDate() works similarly, except it returns a `Date` object.  Note that in both cases the `now` parameter should be milliseconds.
-
-Max-Age takes precedence over Expires (as per the RFC). The `.creation` attribute -- or, by default, the `now` parameter -- is used to offset the `.maxAge` attribute.
-
-If Expires (`.expires`) is set, that's returned.
-
-Otherwise, `expiryTime()` returns `Infinity` and `expiryDate()` returns a `Date` object for "Tue, 19 Jan 2038 03:14:07 GMT" (latest date that can be expressed by a 32-bit `time_t`; the common limit for most user-agents).
-
-### `.TTL([now=Date.now()])`
-
-compute the TTL relative to `now` (milliseconds).  The same precedence rules as for `expiryTime`/`expiryDate` apply.
-
-The "number" `Infinity` is returned for cookies without an explicit expiry and `0` is returned if the cookie is expired.  Otherwise a time-to-live in milliseconds is returned.
-
-### `.canonicalizedDoman()`
-
-### `.cdomain()`
-
-return the canonicalized `.domain` field.  This is lower-cased and punycode (RFC3490) encoded if the domain has any non-ASCII characters.
-
-### `.toJSON()`
-
-For convenience in using `JSON.serialize(cookie)`. Returns a plain-old `Object` that can be JSON-serialized.
-
-Any `Date` properties (i.e., `.expires`, `.creation`, and `.lastAccessed`) are exported in ISO format (`.toISOString()`).
-
-**NOTE**: Custom `Cookie` properties will be discarded. In tough-cookie 1.x, since there was no `.toJSON` method explicitly defined, all enumerable properties were captured. If you want a property to be serialized, add the property name to the `Cookie.serializableProperties` Array.
-
-### `Cookie.fromJSON(strOrObj)`
-
-Does the reverse of `cookie.toJSON()`. If passed a string, will `JSON.parse()` that first.
-
-Any `Date` properties (i.e., `.expires`, `.creation`, and `.lastAccessed`) are parsed via `Date.parse()`, not the tough-cookie `parseDate`, since it's JavaScript/JSON-y timestamps being handled at this layer.
-
-Returns `null` upon JSON parsing error.
-
-### `.clone()`
-
-Does a deep clone of this cookie, exactly implemented as `Cookie.fromJSON(cookie.toJSON())`.
-
-### `.validate()`
-
-Status: *IN PROGRESS*. Works for a few things, but is by no means comprehensive.
-
-validates cookie attributes for semantic correctness.  Useful for "lint" checking any Set-Cookie headers you generate.  For now, it returns a boolean, but eventually could return a reason string -- you can future-proof with this construct:
-
-``` javascript
-if (cookie.validate() === true) {
-  // it's tasty
-} else {
-  // yuck!
-}
-```
-
-
-## CookieJar
-
-Exported via `tough.CookieJar`.
-
-### `CookieJar([store],[options])`
-
-Simply use `new CookieJar()`.  If you'd like to use a custom store, pass that to the constructor otherwise a `MemoryCookieStore` will be created and used.
-
-The `options` object can be omitted and can have the following properties:
-
-  * _rejectPublicSuffixes_ - boolean - default `true` - reject cookies with domains like "com" and "co.uk"
-  * _looseMode_ - boolean - default `false` - accept malformed cookies like `bar` and `=bar`, which have an implied empty name.
-    This is not in the standard, but is used sometimes on the web and is accepted by (most) browsers.
-
-Since eventually this module would like to support database/remote/etc. CookieJars, continuation passing style is used for CookieJar methods.
-
-### `.setCookie(cookieOrString, currentUrl, [{options},] cb(err,cookie))`
-
-Attempt to set the cookie in the cookie jar.  If the operation fails, an error will be given to the callback `cb`, otherwise the cookie is passed through.  The cookie will have updated `.creation`, `.lastAccessed` and `.hostOnly` properties.
-
-The `options` object can be omitted and can have the following properties:
-
-  * _http_ - boolean - default `true` - indicates if this is an HTTP or non-HTTP API.  Affects HttpOnly cookies.
-  * _secure_ - boolean - autodetect from url - indicates if this is a "Secure" API.  If the currentUrl starts with `https:` or `wss:` then this is defaulted to `true`, otherwise `false`.
-  * _now_ - Date - default `new Date()` - what to use for the creation/access time of cookies
-  * _ignoreError_ - boolean - default `false` - silently ignore things like parse errors and invalid domains.  `Store` errors aren't ignored by this option.
-
-As per the RFC, the `.hostOnly` property is set if there was no "Domain=" parameter in the cookie string (or `.domain` was null on the Cookie object).  The `.domain` property is set to the fully-qualified hostname of `currentUrl` in this case.  Matching this cookie requires an exact hostname match (not a `domainMatch` as per usual).
-
-### `.setCookieSync(cookieOrString, currentUrl, [{options}])`
-
-Synchronous version of `setCookie`; only works with synchronous stores (e.g. the default `MemoryCookieStore`).
-
-### `.getCookies(currentUrl, [{options},] cb(err,cookies))`
-
-Retrieve the list of cookies that can be sent in a Cookie header for the current url.
-
-If an error is encountered, that's passed as `err` to the callback, otherwise an `Array` of `Cookie` objects is passed.  The array is sorted with `cookieCompare()` unless the `{sort:false}` option is given.
-
-The `options` object can be omitted and can have the following properties:
-
-  * _http_ - boolean - default `true` - indicates if this is an HTTP or non-HTTP API.  Affects HttpOnly cookies.
-  * _secure_ - boolean - autodetect from url - indicates if this is a "Secure" API.  If the currentUrl starts with `https:` or `wss:` then this is defaulted to `true`, otherwise `false`.
-  * _now_ - Date - default `new Date()` - what to use for the creation/access time of cookies
-  * _expire_ - boolean - default `true` - perform expiry-time checking of cookies and asynchronously remove expired cookies from the store.  Using `false` will return expired cookies and **not** remove them from the store (which is useful for replaying Set-Cookie headers, potentially).
-  * _allPaths_ - boolean - default `false` - if `true`, do not scope cookies by path. The default uses RFC-compliant path scoping. **Note**: may not be supported by the underlying store (the default `MemoryCookieStore` supports it).
-
-The `.lastAccessed` property of the returned cookies will have been updated.
-
-### `.getCookiesSync(currentUrl, [{options}])`
-
-Synchronous version of `getCookies`; only works with synchronous stores (e.g. the default `MemoryCookieStore`).
-
-### `.getCookieString(...)`
-
-Accepts the same options as `.getCookies()` but passes a string suitable for a Cookie header rather than an array to the callback.  Simply maps the `Cookie` array via `.cookieString()`.
-
-### `.getCookieStringSync(...)`
-
-Synchronous version of `getCookieString`; only works with synchronous stores (e.g. the default `MemoryCookieStore`).
-
-### `.getSetCookieStrings(...)`
-
-Returns an array of strings suitable for **Set-Cookie** headers. Accepts the same options as `.getCookies()`.  Simply maps the cookie array via `.toString()`.
-
-### `.getSetCookieStringsSync(...)`
-
-Synchronous version of `getSetCookieStrings`; only works with synchronous stores (e.g. the default `MemoryCookieStore`).
-
-### `.serialize(cb(err,serializedObject))`
-
-Serialize the Jar if the underlying store supports `.getAllCookies`.
-
-**NOTE**: Custom `Cookie` properties will be discarded. If you want a property to be serialized, add the property name to the `Cookie.serializableProperties` Array.
-
-See [Serialization Format].
-
-### `.serializeSync()`
-
-Sync version of .serialize
-
-### `.toJSON()`
-
-Alias of .serializeSync() for the convenience of `JSON.stringify(cookiejar)`.
-
-### `CookieJar.deserialize(serialized, [store], cb(err,object))`
-
-A new Jar is created and the serialized Cookies are added to the underlying store. Each `Cookie` is added via `store.putCookie` in the order in which they appear in the serialization.
-
-The `store` argument is optional, but should be an instance of `Store`. By default, a new instance of `MemoryCookieStore` is created.
-
-As a convenience, if `serialized` is a string, it is passed through `JSON.parse` first. If that throws an error, this is passed to the callback.
-
-### `CookieJar.deserializeSync(serialized, [store])`
-
-Sync version of `.deserialize`.  _Note_ that the `store` must be synchronous for this to work.
-
-### `CookieJar.fromJSON(string)`
-
-Alias of `.deserializeSync` to provide consistency with `Cookie.fromJSON()`.
-
-### `.clone([store,]cb(err,newJar))`
-
-Produces a deep clone of this jar. Modifications to the original won't affect the clone, and vice versa.
-
-The `store` argument is optional, but should be an instance of `Store`. By default, a new instance of `MemoryCookieStore` is created. Transferring between store types is supported so long as the source implements `.getAllCookies()` and the destination implements `.putCookie()`.
-
-### `.cloneSync([store])`
-
-Synchronous version of `.clone`, returning a new `CookieJar` instance.
-
-The `store` argument is optional, but must be a _synchronous_ `Store` instance if specified. If not passed, a new instance of `MemoryCookieStore` is used.
-
-The _source_ and _destination_ must both be synchronous `Store`s. If one or both stores are asynchronous, use `.clone` instead. Recall that `MemoryCookieStore` supports both synchronous and asynchronous API calls.
-
-## Store
-
-Base class for CookieJar stores. Available as `tough.Store`.
-
-## Store API
-
-The storage model for each `CookieJar` instance can be replaced with a custom implementation.  The default is `MemoryCookieStore` which can be found in the `lib/memstore.js` file.  The API uses continuation-passing-style to allow for asynchronous stores.
-
-Stores should inherit from the base `Store` class, which is available as `require('tough-cookie').Store`.
-
-Stores are asynchronous by default, but if `store.synchronous` is set to `true`, then the `*Sync` methods on the of the containing `CookieJar` can be used (however, the continuation-passing style
-
-All `domain` parameters will have been normalized before calling.
-
-The Cookie store must have all of the following methods.
-
-### `store.findCookie(domain, path, key, cb(err,cookie))`
-
-Retrieve a cookie with the given domain, path and key (a.k.a. name).  The RFC maintains that exactly one of these cookies should exist in a store.  If the store is using versioning, this means that the latest/newest such cookie should be returned.
-
-Callback takes an error and the resulting `Cookie` object.  If no cookie is found then `null` MUST be passed instead (i.e. not an error).
-
-### `store.findCookies(domain, path, cb(err,cookies))`
-
-Locates cookies matching the given domain and path.  This is most often called in the context of `cookiejar.getCookies()` above.
-
-If no cookies are found, the callback MUST be passed an empty array.
-
-The resulting list will be checked for applicability to the current request according to the RFC (domain-match, path-match, http-only-flag, secure-flag, expiry, etc.), so it's OK to use an optimistic search algorithm when implementing this method.  However, the search algorithm used SHOULD try to find cookies that `domainMatch()` the domain and `pathMatch()` the path in order to limit the amount of checking that needs to be done.
-
-As of version 0.9.12, the `allPaths` option to `cookiejar.getCookies()` above will cause the path here to be `null`.  If the path is `null`, path-matching MUST NOT be performed (i.e. domain-matching only).
-
-### `store.putCookie(cookie, cb(err))`
-
-Adds a new cookie to the store.  The implementation SHOULD replace any existing cookie with the same `.domain`, `.path`, and `.key` properties -- depending on the nature of the implementation, it's possible that between the call to `fetchCookie` and `putCookie` that a duplicate `putCookie` can occur.
-
-The `cookie` object MUST NOT be modified; the caller will have already updated the `.creation` and `.lastAccessed` properties.
-
-Pass an error if the cookie cannot be stored.
-
-### `store.updateCookie(oldCookie, newCookie, cb(err))`
-
-Update an existing cookie.  The implementation MUST update the `.value` for a cookie with the same `domain`, `.path` and `.key`.  The implementation SHOULD check that the old value in the store is equivalent to `oldCookie` - how the conflict is resolved is up to the store.
-
-The `.lastAccessed` property will always be different between the two objects (to the precision possible via JavaScript's clock).  Both `.creation` and `.creationIndex` are guaranteed to be the same.  Stores MAY ignore or defer the `.lastAccessed` change at the cost of affecting how cookies are selected for automatic deletion (e.g., least-recently-used, which is up to the store to implement).
-
-Stores may wish to optimize changing the `.value` of the cookie in the store versus storing a new cookie.  If the implementation doesn't define this method a stub that calls `putCookie(newCookie,cb)` will be added to the store object.
-
-The `newCookie` and `oldCookie` objects MUST NOT be modified.
-
-Pass an error if the newCookie cannot be stored.
-
-### `store.removeCookie(domain, path, key, cb(err))`
-
-Remove a cookie from the store (see notes on `findCookie` about the uniqueness constraint).
-
-The implementation MUST NOT pass an error if the cookie doesn't exist; only pass an error due to the failure to remove an existing cookie.
-
-### `store.removeCookies(domain, path, cb(err))`
-
-Removes matching cookies from the store.  The `path` parameter is optional, and if missing means all paths in a domain should be removed.
-
-Pass an error ONLY if removing any existing cookies failed.
-
-### `store.getAllCookies(cb(err, cookies))`
-
-Produces an `Array` of all cookies during `jar.serialize()`. The items in the array can be true `Cookie` objects or generic `Object`s with the [Serialization Format] data structure.
-
-Cookies SHOULD be returned in creation order to preserve sorting via `compareCookies()`. For reference, `MemoryCookieStore` will sort by `.creationIndex` since it uses true `Cookie` objects internally. If you don't return the cookies in creation order, they'll still be sorted by creation time, but this only has a precision of 1ms.  See `compareCookies` for more detail.
-
-Pass an error if retrieval fails.
-
-## MemoryCookieStore
-
-Inherits from `Store`.
-
-A just-in-memory CookieJar synchronous store implementation, used by default. Despite being a synchronous implementation, it's usable with both the synchronous and asynchronous forms of the `CookieJar` API.
-
-## Community Cookie Stores
-
-These are some Store implementations authored and maintained by the community. They aren't official and we don't vouch for them but you may be interested to have a look:
-
-- [`db-cookie-store`](https://github.com/JSBizon/db-cookie-store): SQL including SQLite-based databases
-- [`file-cookie-store`](https://github.com/JSBizon/file-cookie-store): Netscape cookie file format on disk
-- [`redis-cookie-store`](https://github.com/benkroeger/redis-cookie-store): Redis
-- [`tough-cookie-filestore`](https://github.com/mitsuru/tough-cookie-filestore): JSON on disk
-- [`tough-cookie-web-storage-store`](https://github.com/exponentjs/tough-cookie-web-storage-store): DOM localStorage and sessionStorage

-
-# Serialization Format
-
-**NOTE**: if you want to have custom `Cookie` properties serialized, add the property name to `Cookie.serializableProperties`.
-
-```js
-  {
-    // The version of tough-cookie that serialized this jar.
-    version: 'tough-cookie@1.x.y',
-
-    // add the store type, to make humans happy:
-    storeType: 'MemoryCookieStore',
-
-    // CookieJar configuration:
-    rejectPublicSuffixes: true,
-    // ... future items go here
-
-    // Gets filled from jar.store.getAllCookies():
-    cookies: [
-      {
-        key: 'string',
-        value: 'string',
-        // ...
-        /* other Cookie.serializableProperties go here */
-      }
-    ]
-  }

-
-A robust Punycode converter that fully complies to [RFC 3492](https://tools.ietf.org/html/rfc3492) and [RFC 5891](https://tools.ietf.org/html/rfc5891), and works on nearly all JavaScript platforms.
-
-This JavaScript library is the result of comparing, optimizing and documenting different open-source implementations of the Punycode algorithm:
-
-* [The C example code from RFC 3492](https://tools.ietf.org/html/rfc3492#appendix-C)
-* [`punycode.c` by _Markus W. Scherer_ (IBM)](http://opensource.apple.com/source/ICU/ICU-400.42/icuSources/common/punycode.c)
-* [`punycode.c` by _Ben Noordhuis_](https://github.com/bnoordhuis/punycode/blob/master/punycode.c)
-* [JavaScript implementation by _some_](http://stackoverflow.com/questions/183485/can-anyone-recommend-a-good-free-javascript-for-punycode-to-unicode-conversion/301287#301287)
-* [`punycode.js` by _Ben Noordhuis_](https://github.com/joyent/node/blob/426298c8c1c0d5b5224ac3658c41e7c2a3fe9377/lib/punycode.js) (note: [not fully compliant](https://github.com/joyent/node/issues/2072))
-
-This project is [bundled](https://github.com/joyent/node/blob/master/lib/punycode.js) with [Node.js v0.6.2+](https://github.com/joyent/node/compare/975f1930b1...61e796decc) and [io.js v1.0.0+](https://github.com/iojs/io.js/blob/v1.x/lib/punycode.js).
-
-## Installation
-
-Via [npm](https://www.npmjs.com/) (only required for Node.js releases older than v0.6.2):
-
-```bash
-npm install punycode
-```
-
-Via [Bower](http://bower.io/):
-
-```bash
-bower install punycode
-```
-
-Via [Component](https://github.com/component/component):
-
-```bash
-component install bestiejs/punycode.js
-```
-
-In a browser:
-
-```html
-<script src="punycode.js"></script>
-```
-
-In [Node.js](https://nodejs.org/), [io.js](https://iojs.org/), [Narwhal](http://narwhaljs.org/), and [RingoJS](http://ringojs.org/):
-
-```js
-var punycode = require('punycode');
-```
-
-In [Rhino](http://www.mozilla.org/rhino/):
-
-```js
-load('punycode.js');
-```
-
-Using an AMD loader like [RequireJS](http://requirejs.org/):
-
-```js
-require(
-  {
-    'paths': {
-      'punycode': 'path/to/punycode'
-    }
-  },
-  ['punycode'],
-  function(punycode) {
-    console.log(punycode);
-  }
-);
-```
-
-## API
-
-### `punycode.decode(string)`
-
-Converts a Punycode string of ASCII symbols to a string of Unicode symbols.
-
-```js
-// decode domain name parts
-punycode.decode('maana-pta'); // 'mañana'
-punycode.decode('--dqo34k'); // '☃-⌘'
-```
-
-### `punycode.encode(string)`
-
-Converts a string of Unicode symbols to a Punycode string of ASCII symbols.
-
-```js
-// encode domain name parts
-punycode.encode('mañana'); // 'maana-pta'
-punycode.encode('☃-⌘'); // '--dqo34k'
-```
-
-### `punycode.toUnicode(input)`
-
-Converts a Punycode string representing a domain name or an email address to Unicode. Only the Punycoded parts of the input will be converted, i.e. it doesn’t matter if you call it on a string that has already been converted to Unicode.
-
-```js
-// decode domain names
-punycode.toUnicode('xn--maana-pta.com');
-// → 'mañana.com'
-punycode.toUnicode('xn----dqo34k.com');
-// → '☃-⌘.com'
-
-// decode email addresses
-punycode.toUnicode('джумла@xn--p-8sbkgc5ag7bhce.xn--ba-lmcq');
-// → 'джумла@джpумлатест.bрфa'
-```
-
-### `punycode.toASCII(input)`
-
-Converts a lowercased Unicode string representing a domain name or an email address to Punycode. Only the non-ASCII parts of the input will be converted, i.e. it doesn’t matter if you call it with a domain that’s already in ASCII.
-
-```js
-// encode domain names
-punycode.toASCII('mañana.com');
-// → 'xn--maana-pta.com'
-punycode.toASCII('☃-⌘.com');
-// → 'xn----dqo34k.com'
-
-// encode email addresses
-punycode.toASCII('джумла@джpумлатест.bрфa');
-// → 'джумла@xn--p-8sbkgc5ag7bhce.xn--ba-lmcq'
-```
-
-### `punycode.ucs2`
-
-#### `punycode.ucs2.decode(string)`
-
-Creates an array containing the numeric code point values of each Unicode symbol in the string. While [JavaScript uses UCS-2 internally](https://mathiasbynens.be/notes/javascript-encoding), this function will convert a pair of surrogate halves (each of which UCS-2 exposes as separate characters) into a single code point, matching UTF-16.
-
-```js
-punycode.ucs2.decode('abc');
-// → [0x61, 0x62, 0x63]
-// surrogate pair for U+1D306 TETRAGRAM FOR CENTRE:
-punycode.ucs2.decode('\uD834\uDF06');
-// → [0x1D306]
-```
-
-#### `punycode.ucs2.encode(codePoints)`
-
-Creates a string based on an array of numeric code point values.
-
-```js
-punycode.ucs2.encode([0x61, 0x62, 0x63]);
-// → 'abc'
-punycode.ucs2.encode([0x1D306]);
-// → '\uD834\uDF06'
-```
-
-### `punycode.version`
-
-A string representing the current Punycode.js version number.
-
-## Unit tests & code coverage
-
-After cloning this repository, run `npm install --dev` to install the dependencies needed for Punycode.js development and testing. You may want to install Istanbul _globally_ using `npm install istanbul -g`.
-
-Once that’s done, you can run the unit tests in Node using `npm test` or `node tests/tests.js`. To run the tests in Rhino, Ringo, Narwhal, PhantomJS, and web browsers as well, use `grunt test`.
-
-To generate the code coverage report, use `grunt cover`.
-
-Feel free to fork if you see possible improvements!

-# true-case-path
-
-## Usage
-
-`trueCasePathSync(<fileSystemPath>)`
-
-## Description
-
-Given a possibly case-variant version of an existing filesystem path, returns
-the case-exact, normalized version as stored in the filesystem.
-
-If the input path is a globbing *pattern* as defined by the 'glob' npm
-package, only the 1st match, if any, is returned.
-Only a literal input path guarantees an unambiguous result.
-
-If no matching path exists, undefined is returned.
-On case-SENSITIVE filesystems, a match will also be found, but if case
-variations of a given path exist, it is undefined which match is returned.
-
-## Platforms
-
-Windows, OSX, and Linux (though note the limitations with case-insensitive filesystems).
-
-## Limitations
-
-- Paths starting with `'./'` are acceptable, but paths starting with `'../'`
-  are not - when in doubt, resolve with `fs.realPathSync()` first.
-  An initial `'.'` and *interior* `'..'` instances are normalized, but a relative
-  input path still results in a relative output path. If you want to ensure
-  an absolute output path, apply `fs.realPathSync()` to the result.
-- On Windows, no attempt is made to case-correct the drive letter or UNC-share
-  component of the path.
-- Unicode support:
-  - Be sure to use UTF8 source-code files (with a BOM on Windows)
-  - On OSX, the input path is automatically converted to NFD Unicode form
-    to match how the filesystem stores names, but note that the result will
-    invariably be NFD too (which makes no difference for ASCII-characters-only
-    names).
-
-## Examples
-
-```
-const trueCasePathSync = require('true-case-path')
-
-trueCasePathSync('/users/guest') // OSX: -> '/Users/Guest'
-
-trueCasePathSync('c:\\users\\all users') // Windows: -> 'c:\Users\All Users'
-```

-
-This is a glob implementation in JavaScript.  It uses the `minimatch`
-library to do its matching.
-
-![](logo/glob.png)
-
-## Usage
-
-Install with npm
-
-```
-npm i glob
-```
-
-```javascript
-var glob = require("glob")
-
-// options is optional
-glob("**/*.js", options, function (er, files) {
-  // files is an array of filenames.
-  // If the `nonull` option is set, and nothing
-  // was found, then files is ["**/*.js"]
-  // er is an error object or null.
-})
-```
-
-## Glob Primer
-
-"Globs" are the patterns you type when you do stuff like `ls *.js` on
-the command line, or put `build/*` in a `.gitignore` file.
-
-Before parsing the path part patterns, braced sections are expanded
-into a set.  Braced sections start with `{` and end with `}`, with any
-number of comma-delimited sections within.  Braced sections may contain
-slash characters, so `a{/b/c,bcd}` would expand into `a/b/c` and `abcd`.
-
-The following characters have special magic meaning when used in a
-path portion:
-
-* `*` Matches 0 or more characters in a single path portion
-* `?` Matches 1 character
-* `[...]` Matches a range of characters, similar to a RegExp range.
-  If the first character of the range is `!` or `^` then it matches
-  any character not in the range.
-* `!(pattern|pattern|pattern)` Matches anything that does not match
-  any of the patterns provided.
-* `?(pattern|pattern|pattern)` Matches zero or one occurrence of the
-  patterns provided.
-* `+(pattern|pattern|pattern)` Matches one or more occurrences of the
-  patterns provided.
-* `*(a|b|c)` Matches zero or more occurrences of the patterns provided
-* `@(pattern|pat*|pat?erN)` Matches exactly one of the patterns
-  provided
-* `**` If a "globstar" is alone in a path portion, then it matches
-  zero or more directories and subdirectories searching for matches.
-  It does not crawl symlinked directories.
-
-### Dots
-
-If a file or directory path portion has a `.` as the first character,
-then it will not match any glob pattern unless that pattern's
-corresponding path part also has a `.` as its first character.
-
-For example, the pattern `a/.*/c` would match the file at `a/.b/c`.
-However the pattern `a/*/c` would not, because `*` does not start with
-a dot character.
-
-You can make glob treat dots as normal characters by setting
-`dot:true` in the options.
-
-### Basename Matching
-
-If you set `matchBase:true` in the options, and the pattern has no
-slashes in it, then it will seek for any file anywhere in the tree
-with a matching basename.  For example, `*.js` would match
-`test/simple/basic.js`.
-
-### Empty Sets
-
-If no matching files are found, then an empty array is returned.  This
-differs from the shell, where the pattern itself is returned.  For
-example:
-
-    $ echo a*s*d*f
-    a*s*d*f
-
-To get the bash-style behavior, set the `nonull:true` in the options.
-

-* `man sh`
-* `man bash` (Search for "Pattern Matching")
-* `man 3 fnmatch`
-* `man 5 gitignore`

-
-## glob.hasMagic(pattern, [options])
-
-Returns `true` if there are any special characters in the pattern, and
-`false` otherwise.
-
-Note that the options affect the results.  If `noext:true` is set in
-the options object, then `+(a|b)` will not be considered a magic
-pattern.  If the pattern has a brace expansion, like `a/{b/c,x/y}`
-then that is considered magical, unless `nobrace:true` is set in the
-options.
-
-## glob(pattern, [options], cb)
-
-* `pattern` `{String}` Pattern to be matched
-* `options` `{Object}`
-* `cb` `{Function}`
-  * `err` `{Error | null}`
-  * `matches` `{Array<String>}` filenames found matching the pattern
-
-Perform an asynchronous glob search.
-
-## glob.sync(pattern, [options])
-
-* `pattern` `{String}` Pattern to be matched
-* `options` `{Object}`
-* return: `{Array<String>}` filenames found matching the pattern
-
-Perform a synchronous glob search.
-
-## Class: glob.Glob
-
-Create a Glob object by instantiating the `glob.Glob` class.
-
-```javascript
-var Glob = require("glob").Glob
-var mg = new Glob(pattern, options, cb)
-```
-
-It's an EventEmitter, and starts walking the filesystem to find matches
-immediately.
-
-### new glob.Glob(pattern, [options], [cb])
-
-* `pattern` `{String}` pattern to search for
-* `options` `{Object}`
-* `cb` `{Function}` Called when an error occurs, or matches are found
-  * `err` `{Error | null}`
-  * `matches` `{Array<String>}` filenames found matching the pattern
-
-Note that if the `sync` flag is set in the options, then matches will
-be immediately available on the `g.found` member.
-
-### Properties
-
-* `minimatch` The minimatch object that the glob uses.
-* `options` The options object passed in.
-* `aborted` Boolean which is set to true when calling `abort()`.  There
-  is no way at this time to continue a glob search after aborting, but
-  you can re-use the statCache to avoid having to duplicate syscalls.
-* `cache` Convenience object.  Each field has the following possible
-  values:
-  * `false` - Path does not exist
-  * `true` - Path exists
-  * `'FILE'` - Path exists, and is not a directory
-  * `'DIR'` - Path exists, and is a directory
-  * `[file, entries, ...]` - Path exists, is a directory, and the
-    array value is the results of `fs.readdir`
-* `statCache` Cache of `fs.stat` results, to prevent statting the same
-  path multiple times.
-* `symlinks` A record of which paths are symbolic links, which is
-  relevant in resolving `**` patterns.
-* `realpathCache` An optional object which is passed to `fs.realpath`
-  to minimize unnecessary syscalls.  It is stored on the instantiated
-  Glob object, and may be re-used.
-
-### Events
-
-* `end` When the matching is finished, this is emitted with all the
-  matches found.  If the `nonull` option is set, and no match was found,
-  then the `matches` list contains the original pattern.  The matches
-  are sorted, unless the `nosort` flag is set.
-* `match` Every time a match is found, this is emitted with the specific
-  thing that matched. It is not deduplicated or resolved to a realpath.
-* `error` Emitted when an unexpected error is encountered, or whenever
-  any fs error occurs if `options.strict` is set.
-* `abort` When `abort()` is called, this event is raised.
-
-### Methods
-
-* `pause` Temporarily stop the search
-* `resume` Resume the search
-* `abort` Stop the search forever
-
-### Options
-
-All the options that can be passed to Minimatch can also be passed to
-Glob to change pattern matching behavior.  Also, some have been added,
-or have glob-specific ramifications.
-
-All options are false by default, unless otherwise noted.
-
-All options are added to the Glob object, as well.
-
-If you are running many `glob` operations, you can pass a Glob object
-as the `options` argument to a subsequent operation to shortcut some
-`stat` and `readdir` calls.  At the very least, you may pass in shared
-`symlinks`, `statCache`, `realpathCache`, and `cache` options, so that
-parallel glob operations will be sped up by sharing information about
-the filesystem.
-
-* `cwd` The current working directory in which to search.  Defaults
-  to `process.cwd()`.
-* `root` The place where patterns starting with `/` will be mounted
-  onto.  Defaults to `path.resolve(options.cwd, "/")` (`/` on Unix
-  systems, and `C:\` or some such on Windows.)
-* `dot` Include `.dot` files in normal matches and `globstar` matches.
-  Note that an explicit dot in a portion of the pattern will always
-  match dot files.
-* `nomount` By default, a pattern starting with a forward-slash will be
-  "mounted" onto the root setting, so that a valid filesystem path is
-  returned.  Set this flag to disable that behavior.
-* `mark` Add a `/` character to directory matches.  Note that this
-  requires additional stat calls.
-* `nosort` Don't sort the results.
-* `stat` Set to true to stat *all* results.  This reduces performance
-  somewhat, and is completely unnecessary, unless `readdir` is presumed
-  to be an untrustworthy indicator of file existence.
-* `silent` When an unusual error is encountered when attempting to
-  read a directory, a warning will be printed to stderr.  Set the
-  `silent` option to true to suppress these warnings.
-* `strict` When an unusual error is encountered when attempting to
-  read a directory, the process will just continue on in search of
-  other matches.  Set the `strict` option to raise an error in these
-  cases.
-* `cache` See `cache` property above.  Pass in a previously generated
-  cache object to save some fs calls.
-* `statCache` A cache of results of filesystem information, to prevent
-  unnecessary stat calls.  While it should not normally be necessary
-  to set this, you may pass the statCache from one glob() call to the
-  options object of another, if you know that the filesystem will not
-  change between calls.  (See "Race Conditions" below.)
-* `symlinks` A cache of known symbolic links.  You may pass in a
-  previously generated `symlinks` object to save `lstat` calls when
-  resolving `**` matches.
-* `sync` DEPRECATED: use `glob.sync(pattern, opts)` instead.
-* `nounique` In some cases, brace-expanded patterns can result in the
-  same file showing up multiple times in the result set.  By default,
-  this implementation prevents duplicates in the result set.  Set this
-  flag to disable that behavior.
-* `nonull` Set to never return an empty set, instead returning a set
-  containing the pattern itself.  This is the default in glob(3).
-* `debug` Set to enable debug logging in minimatch and glob.
-* `nobrace` Do not expand `{a,b}` and `{1..3}` brace sets.
-* `noglobstar` Do not match `**` against multiple filenames.  (Ie,
-  treat it as a normal `*` instead.)
-* `noext` Do not match `+(a|b)` "extglob" patterns.
-* `nocase` Perform a case-insensitive match.  Note: on
-  case-insensitive filesystems, non-magic patterns will match by
-  default, since `stat` and `readdir` will not raise errors.
-* `matchBase` Perform a basename-only match if the pattern does not
-  contain any slash characters.  That is, `*.js` would be treated as
-  equivalent to `**/*.js`, matching all js files in all directories.
-* `nodir` Do not match directories, only files.  (Note: to match
-  *only* directories, simply put a `/` at the end of the pattern.)
-* `ignore` Add a pattern or an array of glob patterns to exclude matches.
-  Note: `ignore` patterns are *always* in `dot:true` mode, regardless
-  of any other settings.
-* `follow` Follow symlinked directories when expanding `**` patterns.
-  Note that this can result in a lot of duplicate references in the
-  presence of cyclic links.
-* `realpath` Set to true to call `fs.realpath` on all of the results.
-  In the case of a symlink that cannot be resolved, the full absolute
-  path to the matched entry is returned (though it will usually be a
-  broken symlink)
-* `absolute` Set to true to always receive absolute paths for matched
-  files.  Unlike `realpath`, this also affects the values returned in
-  the `match` event.
-
-## Comparisons to other fnmatch/glob implementations
-
-While strict compliance with the existing standards is a worthwhile
-goal, some discrepancies exist between node-glob and other
-implementations, and are intentional.
-
-The double-star character `**` is supported by default, unless the
-`noglobstar` flag is set.  This is supported in the manner of bsdglob
-and bash 4.3, where `**` only has special significance if it is the only
-thing in a path part.  That is, `a/**/b` will match `a/x/y/b`, but
-`a/**b` will not.
-
-Note that symlinked directories are not crawled as part of a `**`,
-though their contents may match against subsequent portions of the
-pattern.  This prevents infinite loops and duplicates and the like.
-
-If an escaped pattern has no matches, and the `nonull` flag is set,
-then glob returns the pattern as-provided, rather than
-interpreting the character escapes.  For example,
-`glob.match([], "\\*a\\?")` will return `"\\*a\\?"` rather than
-`"*a?"`.  This is akin to setting the `nullglob` option in bash, except
-that it does not resolve escaped pattern characters.
-
-If brace expansion is not disabled, then it is performed before any
-other interpretation of the glob pattern.  Thus, a pattern like
-`+(a|{b),c)}`, which would not be valid in bash or zsh, is expanded
-**first** into the set of `+(a|b)` and `+(a|c)`, and those patterns are
-checked for validity.  Since those two are valid, matching proceeds.
-
-### Comments and Negation
-
-Previously, this module let you mark a pattern as a "comment" if it
-started with a `#` character, or a "negated" pattern if it started
-with a `!` character.
-
-These options were deprecated in version 5, and removed in version 6.
-
-To specify things that should not match, use the `ignore` option.
-
-## Windows
-
-**Please only use forward-slashes in glob expressions.**
-
-Though windows uses either `/` or `\` as its path separator, only `/`
-characters are used by this glob implementation.  You must use
-forward-slashes **only** in glob expressions.  Back-slashes will always
-be interpreted as escape characters, not path separators.
-
-Results from absolute patterns such as `/foo/*` are mounted onto the
-root setting using `path.join`.  On windows, this will by default result
-in `/foo/*` matching `C:\foo\bar.txt`.
-
-## Race Conditions
-
-Glob searching, by its very nature, is susceptible to race conditions,
-since it relies on directory walking and such.
-
-As a result, it is possible that a file that exists when glob looks for
-it may have been deleted or modified by the time it returns the result.
-
-As part of its internal implementation, this program caches all stat
-and readdir calls that it makes, in order to cut down on system
-overhead.  However, this also makes it even more susceptible to races,
-especially if the cache or statCache objects are reused between glob
-calls.
-
-Users are thus advised not to use a glob result as a guarantee of
-filesystem state in the face of rapid changes.  For the vast majority
-of operations, this is never a problem.

-# minimatch
-
-A minimal matching utility.
-
-[![Build Status](https://secure.travis-ci.org/isaacs/minimatch.svg)](http://travis-ci.org/isaacs/minimatch)
-
-
-This is the matching library used internally by npm.
-
-It works by converting glob expressions into JavaScript `RegExp`
-objects.
-
-## Usage
-
-```javascript
-var minimatch = require("minimatch")
-
-minimatch("bar.foo", "*.foo") // true!
-minimatch("bar.foo", "*.bar") // false!
-minimatch("bar.foo", "*.+(bar|foo)", { debug: true }) // true, and noisy!
-```
-
-## Features
-
-Supports these glob features:
-

-## Minimatch Class
-
-Create a minimatch object by instantiating the `minimatch.Minimatch` class.
-
-```javascript
-var Minimatch = require("minimatch").Minimatch
-var mm = new Minimatch(pattern, options)
-```
-
-### Properties
-
-* `pattern` The original pattern the minimatch object represents.
-* `options` The options supplied to the constructor.
-* `set` A 2-dimensional array of regexp or string expressions.
-  Each row in the
-  array corresponds to a brace-expanded pattern.  Each item in the row
-  corresponds to a single path-part.  For example, the pattern
-  `{a,b/c}/d` would expand to a set of patterns like:
-
-        [ [ a, d ]
-        , [ b, c, d ] ]
-
-    If a portion of the pattern doesn't have any "magic" in it
-    (that is, it's something like `"foo"` rather than `fo*o?`), then it
-    will be left as a string rather than converted to a regular
-    expression.
-
-* `regexp` Created by the `makeRe` method.  A single regular expression
-  expressing the entire pattern.  This is useful in cases where you wish
-  to use the pattern somewhat like `fnmatch(3)` with `FNM_PATH` enabled.
-* `negate` True if the pattern is negated.
-* `comment` True if the pattern is a comment.
-* `empty` True if the pattern is `""`.
-
-### Methods
-
-* `makeRe` Generate the `regexp` member if necessary, and return it.
-  Will return `false` if the pattern is invalid.
-* `match(fname)` Return true if the filename matches the pattern, or
-  false otherwise.
-* `matchOne(fileArray, patternArray, partial)` Take a `/`-split
-  filename, and match it against a single row in the `regExpSet`.  This
-  method is mainly for internal use, but is exposed so that it can be
-  used by a glob-walker that needs to avoid excessive filesystem calls.
-
-All other methods are internal, and will be called as necessary.
-
-### minimatch(path, pattern, options)
-
-Main export.  Tests a path against the pattern using the options.
-
-```javascript
-var isJS = minimatch(file, "*.js", { matchBase: true })
-```
-
-### minimatch.filter(pattern, options)
-
-Returns a function that tests its
-supplied argument, suitable for use with `Array.filter`.  Example:
-
-```javascript
-var javascripts = fileList.filter(minimatch.filter("*.js", {matchBase: true}))
-```
-
-### minimatch.match(list, pattern, options)
-
-Match against the list of
-files, in the style of fnmatch or glob.  If nothing is matched, and
-options.nonull is set, then return a list containing the pattern itself.
-
-```javascript
-var javascripts = minimatch.match(fileList, "*.js", {matchBase: true}))
-```
-
-### minimatch.makeRe(pattern, options)
-
-Make a regular expression object from the pattern.
-
-## Options
-
-All options are `false` by default.
-
-### debug
-
-Dump a ton of stuff to stderr.
-
-### nobrace
-
-Do not expand `{a,b}` and `{1..3}` brace sets.
-
-### noglobstar
-
-Disable `**` matching against multiple folder names.
-
-### dot
-
-Allow patterns to match filenames starting with a period, even if
-the pattern does not explicitly have a period in that spot.
-
-Note that by default, `a/**/b` will **not** match `a/.d/b`, unless `dot`
-is set.
-
-### noext
-
-Disable "extglob" style patterns like `+(a|b)`.
-
-### nocase
-
-Perform a case-insensitive match.
-
-### nonull
-
-When a match is not found by `minimatch.match`, return a list containing
-the pattern itself if this option is set.  When not set, an empty list
-is returned if there are no matches.
-
-### matchBase
-
-If set, then patterns without slashes will be matched
-against the basename of the path if it contains slashes.  For example,
-`a?b` would match the path `/xyz/123/acb`, but not `/xyz/acb/123`.
-
-### nocomment
-
-Suppress the behavior of treating `#` at the start of a pattern as a
-comment.
-
-### nonegate
-
-Suppress the behavior of treating a leading `!` character as negation.
-
-### flipNegate
-
-Returns from negate expressions the same as if they were not negated.
-(Ie, true on a hit, false on a miss.)
-
-
-## Comparisons to other fnmatch/glob implementations
-
-While strict compliance with the existing standards is a worthwhile
-goal, some discrepancies exist between minimatch and other
-implementations, and are intentional.
-
-If the pattern starts with a `!` character, then it is negated.  Set the
-`nonegate` flag to suppress this behavior, and treat leading `!`
-characters normally.  This is perhaps relevant if you wish to start the
-pattern with a negative extglob pattern like `!(a|B)`.  Multiple `!`
-characters at the start of a pattern will negate the pattern multiple
-times.
-
-If a pattern starts with `#`, then it is treated as a comment, and
-will not match anything.  Use `\#` to match a literal `#` at the
-start of a line, or set the `nocomment` flag to suppress this behavior.
-
-The double-star character `**` is supported by default, unless the
-`noglobstar` flag is set.  This is supported in the manner of bsdglob
-and bash 4.1, where `**` only has special significance if it is the only
-thing in a path part.  That is, `a/**/b` will match `a/x/y/b`, but
-`a/**b` will not.
-
-If an escaped pattern has no matches, and the `nonull` flag is set,
-then minimatch.match returns the pattern as-provided, rather than
-interpreting the character escapes.  For example,
-`minimatch.match([], "\\*a\\?")` will return `"\\*a\\?"` rather than
-`"*a?"`.  This is akin to setting the `nullglob` option in bash, except
-that it does not resolve escaped pattern characters.
-
-If brace expansion is not disabled, then it is performed before any
-other interpretation of the glob pattern.  Thus, a pattern like
-`+(a|{b),c)}`, which would not be valid in bash or zsh, is expanded
-**first** into the set of `+(a|b)` and `+(a|c)`, and those patterns are
-checked for validity.  Since those two are valid, matching proceeds.

-TweetNaCl.js Changelog
-======================
-
-
-v0.14.5
--------
-
-* Fixed incomplete return types in TypeScript typings.
-* Replaced COPYING.txt with LICENSE file, which now has public domain dedication
-  text from The Unlicense. License fields in package.json and bower.json have
-  been set to "Unlicense". The project was and will be in the public domain --
-  this change just makes it easier for automated tools to know about this fact by
-  using the widely recognized and SPDX-compatible template for public domain
-  dedication.
-
-
-v0.14.4
--------
-
-* Added TypeScript type definitions (contributed by @AndSDev).
-* Improved benchmarking code.
-
-
-v0.14.3
--------
-
-Fixed a bug in the fast version of Poly1305 and brought it back.
-
-Thanks to @floodyberry for promptly responding and fixing the original C code:
-
-> "The issue was not properly detecting if st->h was >= 2^130 - 5, coupled with
-> [testing mistake] not catching the failure. The chance of the bug affecting
-> anything in the real world is essentially zero luckily, but it's good to have
-> it fixed."
-
-https://github.com/floodyberry/poly1305-donna/issues/2#issuecomment-202698577
-
-
-v0.14.2
--------
-
-Switched Poly1305 fast version back to original (slow) version due to a bug.
-
-
-v0.14.1
--------
-
-No code changes, just tweaked packaging and added COPYING.txt.
-
-
-v0.14.0
--------
-
-* **Breaking change!** All functions from `nacl.util` have been removed. These
-  functions are no longer available:
-
-      nacl.util.decodeUTF8
-      nacl.util.encodeUTF8
-      nacl.util.decodeBase64
-      nacl.util.encodeBase64
-
-  If want to continue using them, you can include
-  <https://github.com/dchest/tweetnacl-util-js> package:
-
-      <script src="nacl.min.js"></script>
-      <script src="nacl-util.min.js"></script>
-
-  or
-
-      var nacl = require('tweetnacl');
-      nacl.util = require('tweetnacl-util');
-
-  However it is recommended to use better packages that have wider
-  compatibility and better performance. Functions from `nacl.util` were never
-  intended to be robust solution for string conversion and were included for
-  convenience: cryptography library is not the right place for them.
-
-  Currently calling these functions will throw error pointing to
-  `tweetnacl-util-js` (in the next version this error message will be removed).
-
-* Improved detection of available random number generators, making it possible
-  to use `nacl.randomBytes` and related functions in Web Workers without
-  changes.
-
-* Changes to testing (see README).
-
-
-v0.13.3
--------
-
-No code changes.
-
-* Reverted license field in package.json to "Public domain".
-
-* Fixed typo in README.
-
-
-v0.13.2
--------
-
-* Fixed undefined variable bug in fast version of Poly1305. No worries, this
-  bug was *never* triggered.
-
-* Specified CC0 public domain dedication.
-
-* Updated development dependencies.
-
-
-v0.13.1
--------
-
-* Exclude `crypto` and `buffer` modules from browserify builds.
-
-
-v0.13.0
--------
-
-* Made `nacl-fast` the default version in NPM package. Now
-  `require("tweetnacl")` will use fast version; to get the original version,
-  use `require("tweetnacl/nacl.js")`.
-
-* Cleanup temporary array after generating random bytes.
-
-
-v0.12.2
--------
-
-* Improved performance of curve operations, making `nacl.scalarMult`, `nacl.box`,
-  `nacl.sign` and related functions up to 3x faster in `nacl-fast` version.
-
-
-v0.12.1
--------
-
-* Significantly improved performance of Salsa20 (~1.5x faster) and
-  Poly1305 (~3.5x faster) in `nacl-fast` version.
-
-
-v0.12.0
--------
-
-* Instead of using the given secret key directly, TweetNaCl.js now copies it to
-  a new array in `nacl.box.keyPair.fromSecretKey` and
-  `nacl.sign.keyPair.fromSecretKey`.
-
-
-v0.11.2
--------
-
-* Added new constant: `nacl.sign.seedLength`.
-
-
-v0.11.1
--------
-
-* Even faster hash for both short and long inputs (in `nacl-fast`).
-
-
-v0.11.0
--------
-
-* Implement `nacl.sign.keyPair.fromSeed` to enable creation of sign key pairs
-  deterministically from a 32-byte seed. (It behaves like
-  [libsodium's](http://doc.libsodium.org/public-key_cryptography/public-key_signatures.html)
-  `crypto_sign_seed_keypair`: the seed becomes a secret part of the secret key.)
-
-* Fast version now has an improved hash implementation that is 2x-5x faster.
-
-* Fixed benchmarks, which may have produced incorrect measurements.
-
-
-v0.10.1
--------
-
-* Exported undocumented `nacl.lowlevel.crypto_core_hsalsa20`.
-
-
-v0.10.0
--------
-
-* **Signature API breaking change!** `nacl.sign` and `nacl.sign.open` now deal
- with signed messages, and new `nacl.sign.detached` and
- `nacl.sign.detached.verify` are available.
- 
- Previously, `nacl.sign` returned a signature, and `nacl.sign.open` accepted a
- message and "detached" signature. This was unlike NaCl's API, which dealt with
- signed messages (concatenation of signature and message).
- 
- The new API is:
-
-      nacl.sign(message, secretKey) -> signedMessage
-      nacl.sign.open(signedMessage, publicKey) -> message | null
-
- Since detached signatures are common, two new API functions were introduced:
- 
-      nacl.sign.detached(message, secretKey) -> signature
-      nacl.sign.detached.verify(message, signature, publicKey) -> true | false
-
- (Note that it's `verify`, not `open`, and it returns a boolean value, unlike
- `open`, which returns an "unsigned" message.)
-
-* NPM package now comes without `test` directory to keep it small.
-
-
-v0.9.2
-------
-
-* Improved documentation.
-* Fast version: increased theoretical message size limit from 2^32-1 to 2^52
-  bytes in Poly1305 (and thus, secretbox and box). However this has no impact
-  in practice since JavaScript arrays or ArrayBuffers are limited to 32-bit
-  indexes, and most implementations won't allocate more than a gigabyte or so.
-  (Obviously, there are no tests for the correctness of implementation.) Also,
-  it's not recommended to use messages that large without splitting them into
-  smaller packets anyway.
-
-
-v0.9.1
-------
-
-* Initial release

-
-Overview
---------
-
-The primary goal of this project is to produce a translation of TweetNaCl to
-JavaScript which is as close as possible to the original C implementation, plus
-a thin layer of idiomatic high-level API on top of it.
-
-There are two versions, you can use either of them:
-
-* `nacl.js` is the port of TweetNaCl with minimum differences from the
-  original + high-level API.
-
-* `nacl-fast.js` is like `nacl.js`, but with some functions replaced with
-  faster versions.
-
-
-Installation
-------------
-
-You can install TweetNaCl.js via a package manager:
-
-[Bower](http://bower.io):
-
-    $ bower install tweetnacl
-
-[NPM](https://www.npmjs.org/):
-
-    $ npm install tweetnacl
-
-or [download source code](https://github.com/dchest/tweetnacl-js/releases).
-
-
-Usage
------
-
-All API functions accept and return bytes as `Uint8Array`s.  If you need to
-encode or decode strings, use functions from
-<https://github.com/dchest/tweetnacl-util-js> or one of the more robust codec
-packages.
-
-In Node.js v4 and later `Buffer` objects are backed by `Uint8Array`s, so you
-can freely pass them to TweetNaCl.js functions as arguments. The returned
-objects are still `Uint8Array`s, so if you need `Buffer`s, you'll have to
-convert them manually; make sure to convert using copying: `new Buffer(array)`,
-instead of sharing: `new Buffer(array.buffer)`, because some functions return
-subarrays of their buffers.
-
-
-### Public-key authenticated encryption (box)
-
-Implements *curve25519-xsalsa20-poly1305*.
-
-#### nacl.box.keyPair()
-
-Generates a new random key pair for box and returns it as an object with
-`publicKey` and `secretKey` members:

-
-Length of public key in bytes.
-
-#### nacl.box.secretKeyLength = 32
-
-Length of secret key in bytes.

-       secretKey: ...   // Uint8Array with 64-byte secret key
-    }
-
-#### nacl.sign.keyPair.fromSecretKey(secretKey)
-
-Returns a signing key pair with public key corresponding to the given
-64-byte secret key. The secret key must have been generated by

-
-#### nacl.sign.keyPair.fromSeed(seed)
-
-Returns a new signing key pair generated deterministically from a 32-byte seed.

-
-
-### Hashing
-
-Implements *SHA-512*.
-
-#### nacl.hash(message)
-
-Returns SHA-512 hash of the message.
-
-#### nacl.hash.hashLength = 64
-
-Length of hash in bytes.
-
-
-### Random bytes generation
-
-#### nacl.randomBytes(length)
-
-Returns a `Uint8Array` of the given length containing random bytes of
-cryptographic quality.
-
-**Implementation note**
-
-TweetNaCl.js uses the following methods to generate random bytes,
-depending on the platform it runs on:
-
-* `window.crypto.getRandomValues` (WebCrypto standard)
-* `window.msCrypto.getRandomValues` (Internet Explorer 11)
-* `crypto.randomBytes` (Node.js)
-
-If the platform doesn't provide a suitable PRNG, the following functions,
-which require random numbers, will throw exception:
-
-* `nacl.randomBytes`
-* `nacl.box.keyPair`
-* `nacl.sign.keyPair`
-
-Other functions are deterministic and will continue working.
-
-If a platform you are targeting doesn't implement secure random number
-generator, but you somehow have a cryptographically-strong source of entropy
-(not `Math.random`!), and you know what you are doing, you can plug it into
-TweetNaCl.js like this:
-
-    nacl.setPRNG(function(x, n) {
-      // ... copy n random bytes into x ...
-    });
-
-Note that `nacl.setPRNG` *completely replaces* internal random byte generator
-with the one provided.
-
-
-### Constant-time comparison
-
-#### nacl.verify(x, y)
-
-Compares `x` and `y` in constant time and returns `true` if their lengths are
-non-zero and equal, and their contents are equal.
-
-Returns `false` if either of the arguments has zero length, or arguments have
-different lengths, or their contents differ.
-
-
-System requirements
--------------------
-
-TweetNaCl.js supports modern browsers that have a cryptographically secure
-pseudorandom number generator and typed arrays, including the latest versions
-of:
-
-* Chrome
-* Firefox
-* Safari (Mac, iOS)
-* Internet Explorer 11
-
-Other systems:
-
-* Node.js
-
-
-Development and testing
-------------------------
-
-Install NPM modules needed for development:
-
-    $ npm install
-
-To build minified versions:
-
-    $ npm run build
-
-Tests use minified version, so make sure to rebuild it every time you change
-`nacl.js` or `nacl-fast.js`.
-
-### Testing
-
-To run tests in Node.js:
-
-    $ npm run test-node
-
-By default all tests described here work on `nacl.min.js`. To test other
-versions, set environment variable `NACL_SRC` to the file name you want to test.
-For example, the following command will test fast minified version:
-
-    $ NACL_SRC=nacl-fast.min.js npm run test-node
-
-To run full suite of tests in Node.js, including comparing outputs of
-JavaScript port to outputs of the original C version:
-
-    $ npm run test-node-all
-
-To prepare tests for browsers:
-
-    $ npm run build-test-browser
-
-and then open `test/browser/test.html` (or `test/browser/test-fast.html`) to
-run them.
-
-To run headless browser tests with `tape-run` (powered by Electron):
-
-    $ npm run test-browser
-
-(If you get `Error: spawn ENOENT`, install *xvfb*: `sudo apt-get install xvfb`.)
-
-To run tests in both Node and Electron:
-
-    $ npm test
-
-### Benchmarking
-
-To run benchmarks in Node.js:
-
-    $ npm run bench
-    $ NACL_SRC=nacl-fast.min.js npm run bench
-
-To run benchmarks in a browser, open `test/benchmark/bench.html` (or
-`test/benchmark/bench-fast.html`).
-
-
-Benchmarks

-
-(You can run benchmarks on your devices by clicking on the links at the bottom
-of the [home page](https://tweetnacl.js.org)).
-
-In short, with *nacl-fast.js* and 1024-byte messages you can expect to encrypt and
-authenticate more than 57000 messages per second on a typical laptop or more than
-14000 messages per second on a $170 smartphone, sign about 200 and verify 100
-messages per second on a laptop or 60 and 30 messages per second on a smartphone,
-per CPU core (with Web Workers you can do these operations in parallel),
-which is good enough for most applications.

-# URI.js
-
-URI.js is an [RFC 3986](http://www.ietf.org/rfc/rfc3986.txt) compliant, scheme extendable URI parsing/validating/resolving library for all JavaScript environments (browsers, Node.js, etc).
-It is also compliant with the IRI ([RFC 3987](http://www.ietf.org/rfc/rfc3987.txt)), IDNA ([RFC 5890](http://www.ietf.org/rfc/rfc5890.txt)), IPv6 Address ([RFC 5952](http://www.ietf.org/rfc/rfc5952.txt)), IPv6 Zone Identifier ([RFC 6874](http://www.ietf.org/rfc/rfc6874.txt)) specifications.
-
-URI.js has an extensive test suite, and works in all (Node.js, web) environments. It weighs in at 6.2kb (gzipped, 16kb deflated).
-
-## API
-
-### Parsing
-
-	URI.parse("uri://user:pass@example.com:123/one/two.three?q1=a1&q2=a2#body");
-	//returns:
-	//{
-	//  scheme : "uri",
-	//  userinfo : "user:pass",
-	//  host : "example.com",
-	//  port : 123,
-	//  path : "/one/two.three",
-	//  query : "q1=a1&q2=a2",
-	//  fragment : "body"
-	//}
-
-### Serializing
-
-	URI.serialize({scheme : "http", host : "example.com", fragment : "footer"}) === "http://example.com/#footer"
-
-### Resolving
-
-	URI.resolve("uri://a/b/c/d?q", "../../g") === "uri://a/g"
-
-### Normalizing
-
-	URI.normalize("HTTP://ABC.com:80/%7Esmith/home.html") === "http://abc.com/~smith/home.html"
-
-### Comparison
-
-	URI.equal("example://a/b/c/%7Bfoo%7D", "eXAMPLE://a/./b/../b/%63/%7bfoo%7d") === true
-
-### IP Support
-
-	//IPv4 normalization
-	URI.normalize("//192.068.001.000") === "//192.68.1.0"
-
-	//IPv6 normalization
-	URI.normalize("//[2001:0:0DB8::0:0001]") === "//[2001:0:db8::1]"
-
-	//IPv6 zone identifier support
-	URI.parse("//[2001:db8::7%25en1]");
-	//returns:
-	//{
-	//  host : "2001:db8::7%en1"
-	//}
-
-### IRI Support
-
-	//convert IRI to URI
-	URI.serialize(URI.parse("http://examplé.org/rosé")) === "http://xn--exampl-gva.org/ros%C3%A9"
-	//convert URI to IRI
-	URI.serialize(URI.parse("http://xn--exampl-gva.org/ros%C3%A9"), {iri:true}) === "http://examplé.org/rosé"
-
-### Options
-
-All of the above functions can accept an additional options argument that is an object that can contain one or more of the following properties:
-
-*	`scheme` (string)
-
-	Indicates the scheme that the URI should be treated as, overriding the URI's normal scheme parsing behavior.
-
-*	`reference` (string)
-
-	If set to `"suffix"`, it indicates that the URI is in the suffix format, and the validator will use the option's `scheme` property to determine the URI's scheme.
-
-*	`tolerant` (boolean, false)
-
-	If set to `true`, the parser will relax URI resolving rules.
-
-*	`absolutePath` (boolean, false)
-
-	If set to `true`, the serializer will not resolve a relative `path` component.
-
-*	`iri` (boolean, false)
-
-	If set to `true`, the serializer will unescape non-ASCII characters as per [RFC 3987](http://www.ietf.org/rfc/rfc3987.txt).
-
-*	`unicodeSupport` (boolean, false)
-
-	If set to `true`, the parser will unescape non-ASCII characters in the parsed output as per [RFC 3987](http://www.ietf.org/rfc/rfc3987.txt).
-
-*	`domainHost` (boolean, false)
-
-	If set to `true`, the library will treat the `host` component as a domain name, and convert IDNs (International Domain Names) as per [RFC 5891](http://www.ietf.org/rfc/rfc5891.txt).
-
-## Scheme Extendable
-
-URI.js supports inserting custom [scheme](http://en.wikipedia.org/wiki/URI_scheme) dependent processing rules. Currently, URI.js has built in support for the following schemes:
-
-*	http \[[RFC 2616](http://www.ietf.org/rfc/rfc2616.txt)\]
-*	https \[[RFC 2818](http://www.ietf.org/rfc/rfc2818.txt)\]
-*	mailto \[[RFC 6068](http://www.ietf.org/rfc/rfc6068.txt)\]
-*	urn \[[RFC 2141](http://www.ietf.org/rfc/rfc2141.txt)\]
-*	urn:uuid \[[RFC 4122](http://www.ietf.org/rfc/rfc4122.txt)\]
-
-### HTTP Support
-
-	URI.equal("HTTP://ABC.COM:80", "http://abc.com/") === true
-
-### Mailto Support
-
-	URI.parse("mailto:alpha@example.com,bravo@example.com?subject=SUBSCRIBE&body=Sign%20me%20up!");
-	//returns:
-	//{
-	//	scheme : "mailto",
-	//	to : ["alpha@example.com", "bravo@example.com"],
-	//	subject : "SUBSCRIBE",
-	//	body : "Sign me up!"
-	//}
-
-	URI.serialize({
-		scheme : "mailto",
-		to : ["alpha@example.com"],
-		subject : "REMOVE",
-		body : "Please remove me",
-		headers : {
-			cc : "charlie@example.com"
-		}
-	}) === "mailto:alpha@example.com?cc=charlie@example.com&subject=REMOVE&body=Please%20remove%20me"
-
-### URN Support
-
-	URI.parse("urn:example:foo");
-	//returns:
-	//{
-	//	scheme : "urn",
-	//	nid : "example",
-	//	nss : "foo",
-	//}
-
-#### URN UUID Support
-
-	URI.parse("urn:uuid:f81d4fae-7dec-11d0-a765-00a0c91e6bf6");
-	//returns:
-	//{
-	//	scheme : "urn",
-	//	nid : "example",
-	//	uuid : "f81d4fae-7dec-11d0-a765-00a0c91e6bf6",
-	//}
-
-## Usage
-
-To load in a browser, use the following tag:
-
-	<script type="text/javascript" src="uri-js/dist/es5/uri.all.min.js"></script>
-
-To load in a CommonJS (Node.js) environment, first install with npm by running on the command line:
-
-	npm install uri-js
-
-Then, in your code, load it using:
-
-	const URI = require("uri-js");
-
-If you are writing your code in ES6+ (ESNEXT) or TypeScript, you would load it using:
-
-	import * as URI from "uri-js";
-
-Or you can load just what you need using named exports:
-
-	import { parse, serialize, resolve, resolveComponents, normalize, equal, removeDotSegments, pctEncChar, pctDecChars, escapeComponent, unescapeComponent } from "uri-js";
-
-## Breaking changes
-
-### Breaking changes from 3.x
-
-URN parsing has been completely changed to better align with the specification. Scheme is now always `urn`, but has two new properties: `nid` which contains the Namspace Identifier, and `nss` which contains the Namespace Specific String. The `nss` property will be removed by higher order scheme handlers, such as the UUID URN scheme handler.
-
-The UUID of a URN can now be found in the `uuid` property.
-
-### Breaking changes from 2.x
-
-URI validation has been removed as it was slow, exposed a vulnerabilty, and was generally not useful.
-
-### Breaking changes from 1.x
-
-The `errors` array on parsed components is now an `error` string.

-# uuid [![Build Status](https://secure.travis-ci.org/kelektiv/node-uuid.svg?branch=master)](http://travis-ci.org/kelektiv/node-uuid) #
-
-Simple, fast generation of [RFC4122](http://www.ietf.org/rfc/rfc4122.txt) UUIDS.
-
-Features:
-
-* Support for version 1, 3, 4 and 5 UUIDs
-* Cross-platform
-* Uses cryptographically-strong random number APIs (when available)
-* Zero-dependency, small footprint (... but not [this small](https://gist.github.com/982883))
-
-[**Deprecation warning**: The use of `require('uuid')` is deprecated and will not be
-supported after version 3.x of this module.  Instead, use `require('uuid/[v1|v3|v4|v5]')` as shown in the examples below.]
-
-## Quickstart - CommonJS (Recommended)
-
-```shell
-npm install uuid
-```
-
-Then generate your uuid version of choice ...
-
-Version 1 (timestamp):
-
-```javascript
-const uuidv1 = require('uuid/v1');
-uuidv1(); // ⇨ '2c5ea4c0-4067-11e9-8bad-9b1deb4d3b7d'
-
-```
-
-Version 3 (namespace):
-
-```javascript
-const uuidv3 = require('uuid/v3');
-
-// ... using predefined DNS namespace (for domain names)
-uuidv3('hello.example.com', uuidv3.DNS); // ⇨ '9125a8dc-52ee-365b-a5aa-81b0b3681cf6'
-
-// ... using predefined URL namespace (for, well, URLs)
-uuidv3('http://example.com/hello', uuidv3.URL); // ⇨ 'c6235813-3ba4-3801-ae84-e0a6ebb7d138'
-
-// ... using a custom namespace
-//
-// Note: Custom namespaces should be a UUID string specific to your application!
-// E.g. the one here was generated using this modules `uuid` CLI.
-const MY_NAMESPACE = '1b671a64-40d5-491e-99b0-da01ff1f3341';
-uuidv3('Hello, World!', MY_NAMESPACE); // ⇨ 'e8b5a51d-11c8-3310-a6ab-367563f20686'
-
-```
-
-Version 4 (random):
-
-```javascript
-const uuidv4 = require('uuid/v4');
-uuidv4(); // ⇨ '1b9d6bcd-bbfd-4b2d-9b5d-ab8dfbbd4bed'
-
-```
-
-Version 5 (namespace):
-
-```javascript
-const uuidv5 = require('uuid/v5');
-
-// ... using predefined DNS namespace (for domain names)
-uuidv5('hello.example.com', uuidv5.DNS); // ⇨ 'fdda765f-fc57-5604-a269-52a7df8164ec'
-
-// ... using predefined URL namespace (for, well, URLs)
-uuidv5('http://example.com/hello', uuidv5.URL); // ⇨ '3bbcee75-cecc-5b56-8031-b6641c1ed1f1'
-
-// ... using a custom namespace
-//
-// Note: Custom namespaces should be a UUID string specific to your application!
-// E.g. the one here was generated using this modules `uuid` CLI.
-const MY_NAMESPACE = '1b671a64-40d5-491e-99b0-da01ff1f3341';
-uuidv5('Hello, World!', MY_NAMESPACE); // ⇨ '630eb68f-e0fa-5ecc-887a-7c7a62614681'
-
-```
-
-## API
-
-### Version 1
-
-```javascript
-const uuidv1 = require('uuid/v1');
-
-// Incantations
-uuidv1();
-uuidv1(options);
-uuidv1(options, buffer, offset);
-```
-
-Generate and return a RFC4122 v1 (timestamp-based) UUID.
-
-* `options` - (Object) Optional uuid state to apply. Properties may include:
-
-  * `node` - (Array) Node id as Array of 6 bytes (per 4.1.6). Default: Randomly generated ID.  See note 1.
-  * `clockseq` - (Number between 0 - 0x3fff) RFC clock sequence.  Default: An internally maintained clockseq is used.
-  * `msecs` - (Number) Time in milliseconds since unix Epoch.  Default: The current time is used.
-  * `nsecs` - (Number between 0-9999) additional time, in 100-nanosecond units. Ignored if `msecs` is unspecified. Default: internal uuid counter is used, as per 4.2.1.2.
-
-* `buffer` - (Array | Buffer) Array or buffer where UUID bytes are to be written.
-* `offset` - (Number) Starting index in `buffer` at which to begin writing.
-
-Returns `buffer`, if specified, otherwise the string form of the UUID
-
-Note: The default [node id](https://tools.ietf.org/html/rfc4122#section-4.1.6) (the last 12 digits in the UUID) is generated once, randomly, on process startup, and then remains unchanged for the duration of the process.
-
-Example: Generate string UUID with fully-specified options
-
-```javascript
-const v1options = {
-  node: [0x01, 0x23, 0x45, 0x67, 0x89, 0xab],
-  clockseq: 0x1234,
-  msecs: new Date('2011-11-01').getTime(),
-  nsecs: 5678
-};
-uuidv1(v1options); // ⇨ '710b962e-041c-11e1-9234-0123456789ab'
-
-```
-
-Example: In-place generation of two binary IDs
-
-```javascript
-// Generate two ids in an array
-const arr = new Array();
-uuidv1(null, arr, 0);  // ⇨ 
-  // [
-  //    44,  94, 164, 192,  64, 103,
-  //    17, 233, 146,  52, 155,  29,
-  //   235,  77,  59, 125
-  // ]
-uuidv1(null, arr, 16); // ⇨ 
-  // [
-  //    44, 94, 164, 192,  64, 103, 17, 233,
-  //   146, 52, 155,  29, 235,  77, 59, 125,
-  //    44, 94, 164, 193,  64, 103, 17, 233,
-  //   146, 52, 155,  29, 235,  77, 59, 125
-  // ]
-
-```
-
-### Version 3
-
-```javascript
-const uuidv3 = require('uuid/v3');
-
-// Incantations
-uuidv3(name, namespace);
-uuidv3(name, namespace, buffer);
-uuidv3(name, namespace, buffer, offset);
-```
-
-Generate and return a RFC4122 v3 UUID.
-
-* `name` - (String | Array[]) "name" to create UUID with
-* `namespace` - (String | Array[]) "namespace" UUID either as a String or Array[16] of byte values
-* `buffer` - (Array | Buffer) Array or buffer where UUID bytes are to be written.
-* `offset` - (Number) Starting index in `buffer` at which to begin writing. Default = 0
-
-Returns `buffer`, if specified, otherwise the string form of the UUID
-
-Example:
-
-```javascript
-uuidv3('hello world', MY_NAMESPACE);  // ⇨ '042ffd34-d989-321c-ad06-f60826172424'
-
-```
-
-### Version 4
-
-```javascript
-const uuidv4 = require('uuid/v4')
-
-// Incantations
-uuidv4();
-uuidv4(options);
-uuidv4(options, buffer, offset);
-```
-
-Generate and return a RFC4122 v4 UUID.
-
-* `options` - (Object) Optional uuid state to apply. Properties may include:
-  * `random` - (Number[16]) Array of 16 numbers (0-255) to use in place of randomly generated values
-  * `rng` - (Function) Random # generator function that returns an Array[16] of byte values (0-255)
-* `buffer` - (Array | Buffer) Array or buffer where UUID bytes are to be written.
-* `offset` - (Number) Starting index in `buffer` at which to begin writing.
-
-Returns `buffer`, if specified, otherwise the string form of the UUID
-
-Example: Generate string UUID with predefined `random` values
-
-```javascript
-const v4options = {
-  random: [
-    0x10, 0x91, 0x56, 0xbe, 0xc4, 0xfb, 0xc1, 0xea,
-    0x71, 0xb4, 0xef, 0xe1, 0x67, 0x1c, 0x58, 0x36
-  ]
-};
-uuidv4(v4options); // ⇨ '109156be-c4fb-41ea-b1b4-efe1671c5836'
-
-```
-
-Example: Generate two IDs in a single buffer
-
-```javascript
-const buffer = new Array();
-uuidv4(null, buffer, 0);  // ⇨ 
-  // [
-  //   155, 29, 235,  77,  59,
-  //   125, 75, 173, 155, 221,
-  //    43, 13, 123,  61, 203,
-  //   109
-  // ]
-uuidv4(null, buffer, 16); // ⇨ 
-  // [
-  //   155,  29, 235,  77,  59, 125,  75, 173,
-  //   155, 221,  43,  13, 123,  61, 203, 109,
-  //    27, 157, 107, 205, 187, 253,  75,  45,
-  //   155,  93, 171, 141, 251, 189,  75, 237
-  // ]
-
-```

-# verror: rich JavaScript errors
-
-This module provides several classes in support of Joyent's [Best Practices for
-Error Handling in Node.js](http://www.joyent.com/developers/node/design/errors).
-If you find any of the behavior here confusing or surprising, check out that
-document first.
-
-The error classes here support:
-
-* printf-style arguments for the message
-* chains of causes
-* properties to provide extra information about the error
-* creating your own subclasses that support all of these
-
-The classes here are:
-
-* **VError**, for chaining errors while preserving each one's error message.
-  This is useful in servers and command-line utilities when you want to
-  propagate an error up a call stack, but allow various levels to add their own
-  context.  See examples below.
-* **WError**, for wrapping errors while hiding the lower-level messages from the
-  top-level error.  This is useful for API endpoints where you don't want to
-  expose internal error messages, but you still want to preserve the error chain
-  for logging and debugging.
-* **SError**, which is just like VError but interprets printf-style arguments
-  more strictly.
-* **MultiError**, which is just an Error that encapsulates one or more other
-  errors.  (This is used for parallel operations that return several errors.)
-
-
-# Quick start
-
-First, install the package:
-
-    npm install verror
-
-If nothing else, you can use VError as a drop-in replacement for the built-in
-JavaScript Error class, with the addition of printf-style messages:
-
-```javascript
-var err = new VError('missing file: "%s"', '/etc/passwd');
-console.log(err.message);
-```
-
-This prints:
-
-    missing file: "/etc/passwd"
-
-You can also pass a `cause` argument, which is any other Error object:
-
-```javascript
-var fs = require('fs');
-var filename = '/nonexistent';
-fs.stat(filename, function (err1) {
-	var err2 = new VError(err1, 'stat "%s"', filename);
-	console.error(err2.message);
-});
-```
-
-This prints out:
-
-    stat "/nonexistent": ENOENT, stat '/nonexistent'
-
-which resembles how Unix programs typically report errors:
-
-    $ sort /nonexistent
-    sort: open failed: /nonexistent: No such file or directory
-
-To match the Unixy feel, when you print out the error, just prepend the
-program's name to the VError's `message`.  Or just call
-[node-cmdutil.fail(your_verror)](https://github.com/joyent/node-cmdutil), which
-does this for you.
-
-You can get the next-level Error using `err.cause()`:
-
-```javascript
-console.error(err2.cause().message);
-```
-
-prints:
-
-    ENOENT, stat '/nonexistent'
-
-Of course, you can chain these as many times as you want, and it works with any
-kind of Error:
-
-```javascript
-var err1 = new Error('No such file or directory');
-var err2 = new VError(err1, 'failed to stat "%s"', '/junk');
-var err3 = new VError(err2, 'request failed');
-console.error(err3.message);
-```
-
-This prints:
-
-    request failed: failed to stat "/junk": No such file or directory
-
-The idea is that each layer in the stack annotates the error with a description
-of what it was doing.  The end result is a message that explains what happened
-at each level.
-
-You can also decorate Error objects with additional information so that callers
-can not only handle each kind of error differently, but also construct their own
-error messages (e.g., to localize them, format them, group them by type, and so
-on).  See the example below.
-
-
-# Deeper dive
-
-The two main goals for VError are:
-
-* **Make it easy to construct clear, complete error messages intended for
-  people.**  Clear error messages greatly improve both user experience and
-  debuggability, so we wanted to make it easy to build them.  That's why the
-  constructor takes printf-style arguments.
-* **Make it easy to construct objects with programmatically-accessible
-  metadata** (which we call _informational properties_).  Instead of just saying
-  "connection refused while connecting to 192.168.1.2:80", you can add
-  properties like `"ip": "192.168.1.2"` and `"tcpPort": 80`.  This can be used
-  for feeding into monitoring systems, analyzing large numbers of Errors (as
-  from a log file), or localizing error messages.
-
-To really make this useful, it also needs to be easy to compose Errors:
-higher-level code should be able to augment the Errors reported by lower-level
-code to provide a more complete description of what happened.  Instead of saying
-"connection refused", you can say "operation X failed: connection refused".
-That's why VError supports `causes`.
-
-In order for all this to work, programmers need to know that it's generally safe
-to wrap lower-level Errors with higher-level ones.  If you have existing code
-that handles Errors produced by a library, you should be able to wrap those
-Errors with a VError to add information without breaking the error handling
-code.  There are two obvious ways that this could break such consumers:
-
-* The error's name might change.  People typically use `name` to determine what
-  kind of Error they've got.  To ensure compatibility, you can create VErrors
-  with custom names, but this approach isn't great because it prevents you from
-  representing complex failures.  For this reason, VError provides
-  `findCauseByName`, which essentially asks: does this Error _or any of its
-  causes_ have this specific type?  If error handling code uses
-  `findCauseByName`, then subsystems can construct very specific causal chains
-  for debuggability and still let people handle simple cases easily.  There's an
-  example below.
-* The error's properties might change.  People often hang additional properties
-  off of Error objects.  If we wrap an existing Error in a new Error, those
-  properties would be lost unless we copied them.  But there are a variety of
-  both standard and non-standard Error properties that should _not_ be copied in
-  this way: most obviously `name`, `message`, and `stack`, but also `fileName`,
-  `lineNumber`, and a few others.  Plus, it's useful for some Error subclasses
-  to have their own private properties -- and there'd be no way to know whether
-  these should be copied.  For these reasons, VError first-classes these
-  information properties.  You have to provide them in the constructor, you can
-  only fetch them with the `info()` function, and VError takes care of making
-  sure properties from causes wind up in the `info()` output.
-
-Let's put this all together with an example from the node-fast RPC library.
-node-fast implements a simple RPC protocol for Node programs.  There's a server
-and client interface, and clients make RPC requests to servers.  Let's say the
-server fails with an UnauthorizedError with message "user 'bob' is not
-authorized".  The client wraps all server errors with a FastServerError.  The
-client also wraps all request errors with a FastRequestError that includes the
-name of the RPC call being made.  The result of this failed RPC might look like
-this:
-
-    name: FastRequestError
-    message: "request failed: server error: user 'bob' is not authorized"
-    rpcMsgid: <unique identifier for this request>
-    rpcMethod: GetObject
-    cause:
-        name: FastServerError
-        message: "server error: user 'bob' is not authorized"
-        cause:
-            name: UnauthorizedError
-            message: "user 'bob' is not authorized"
-            rpcUser: "bob"
-
-When the caller uses `VError.info()`, the information properties are collapsed
-so that it looks like this:
-
-    message: "request failed: server error: user 'bob' is not authorized"
-    rpcMsgid: <unique identifier for this request>
-    rpcMethod: GetObject
-    rpcUser: "bob"
-
-Taking this apart:
-
-* The error's message is a complete description of the problem.  The caller can
-  report this directly to its caller, which can potentially make its way back to
-  an end user (if appropriate).  It can also be logged.
-* The caller can tell that the request failed on the server, rather than as a
-  result of a client problem (e.g., failure to serialize the request), a
-  transport problem (e.g., failure to connect to the server), or something else
-  (e.g., a timeout).  They do this using `findCauseByName('FastServerError')`
-  rather than checking the `name` field directly.
-* If the caller logs this error, the logs can be analyzed to aggregate
-  errors by cause, by RPC method name, by user, or whatever.  Or the
-  error can be correlated with other events for the same rpcMsgid.
-* It wasn't very hard for any part of the code to contribute to this Error.
-  Each part of the stack has just a few lines to provide exactly what it knows,
-  with very little boilerplate.
-
-It's not expected that you'd use these complex forms all the time.  Despite
-supporting the complex case above, you can still just do:
-
-   new VError("my service isn't working");
-
-for the simple cases.
-
-
-# Reference: VError, WError, SError
-
-VError, WError, and SError are convenient drop-in replacements for `Error` that
-support printf-style arguments, first-class causes, informational properties,
-and other useful features.
-
-
-## Constructors
-
-The VError constructor has several forms:
-
-```javascript
-/*
- * This is the most general form.  You can specify any supported options
- * (including "cause" and "info") this way.
- */
-new VError(options, sprintf_args...)
-
-/*
- * This is a useful shorthand when the only option you need is "cause".
- */
-new VError(cause, sprintf_args...)
-
-/*
- * This is a useful shorthand when you don't need any options at all.
- */
-new VError(sprintf_args...)
-```
-
-All of these forms construct a new VError that behaves just like the built-in
-JavaScript `Error` class, with some additional methods described below.
-
-In the first form, `options` is a plain object with any of the following
-optional properties:
-
-Option name      | Type             | Meaning
----------------- | ---------------- | -------
-`name`           | string           | Describes what kind of error this is.  This is intended for programmatic use to distinguish between different kinds of errors.  Note that in modern versions of Node.js, this name is ignored in the `stack` property value, but callers can still use the `name` property to get at it.
-`cause`          | any Error object | Indicates that the new error was caused by `cause`.  See `cause()` below.  If unspecified, the cause will be `null`.
-`strict`         | boolean          | If true, then `null` and `undefined` values in `sprintf_args` are passed through to `sprintf()`.  Otherwise, these are replaced with the strings `'null'`, and '`undefined`', respectively.
-`constructorOpt` | function         | If specified, then the stack trace for this error ends at function `constructorOpt`.  Functions called by `constructorOpt` will not show up in the stack.  This is useful when this class is subclassed.
-`info`           | object           | Specifies arbitrary informational properties that are available through the `VError.info(err)` static class method.  See that method for details.
-
-The second form is equivalent to using the first form with the specified `cause`
-as the error's cause.  This form is distinguished from the first form because
-the first argument is an Error.
-
-The third form is equivalent to using the first form with all default option
-values.  This form is distinguished from the other forms because the first
-argument is not an object or an Error.
-
-The `WError` constructor is used exactly the same way as the `VError`
-constructor.  The `SError` constructor is also used the same way as the
-`VError` constructor except that in all cases, the `strict` property is
-overriden to `true.
-
-
-## Public properties
-
-`VError`, `WError`, and `SError` all provide the same public properties as
-JavaScript's built-in Error objects.
-
-Property name | Type   | Meaning
-------------- | ------ | -------
-`name`        | string | Programmatically-usable name of the error.
-`message`     | string | Human-readable summary of the failure.  Programmatically-accessible details are provided through `VError.info(err)` class method.
-`stack`       | string | Human-readable stack trace where the Error was constructed.
-
-For all of these classes, the printf-style arguments passed to the constructor
-are processed with `sprintf()` to form a message.  For `WError`, this becomes
-the complete `message` property.  For `SError` and `VError`, this message is
-prepended to the message of the cause, if any (with a suitable separator), and
-the result becomes the `message` property.
-
-The `stack` property is managed entirely by the underlying JavaScript
-implementation.  It's generally implemented using a getter function because
-constructing the human-readable stack trace is somewhat expensive.
-
-## Class methods
-
-The following methods are defined on the `VError` class and as exported
-functions on the `verror` module.  They're defined this way rather than using
-methods on VError instances so that they can be used on Errors not created with
-`VError`.
-
-### `VError.cause(err)`
-
-The `cause()` function returns the next Error in the cause chain for `err`, or
-`null` if there is no next error.  See the `cause` argument to the constructor.
-Errors can have arbitrarily long cause chains.  You can walk the `cause` chain
-by invoking `VError.cause(err)` on each subsequent return value.  If `err` is
-not a `VError`, the cause is `null`.
-
-### `VError.info(err)`
-
-Returns an object with all of the extra error information that's been associated
-with this Error and all of its causes.  These are the properties passed in using
-the `info` option to the constructor.  Properties not specified in the
-constructor for this Error are implicitly inherited from this error's cause.
-
-These properties are intended to provide programmatically-accessible metadata
-about the error.  For an error that indicates a failure to resolve a DNS name,
-informational properties might include the DNS name to be resolved, or even the
-list of resolvers used to resolve it.  The values of these properties should
-generally be plain objects (i.e., consisting only of null, undefined, numbers,
-booleans, strings, and objects and arrays containing only other plain objects).
-
-### `VError.fullStack(err)`
-
-Returns a string containing the full stack trace, with all nested errors recursively
-reported as `'caused by:' + err.stack`.
-
-### `VError.findCauseByName(err, name)`
-
-The `findCauseByName()` function traverses the cause chain for `err`, looking
-for an error whose `name` property matches the passed in `name` value. If no
-match is found, `null` is returned.
-
-If all you want is to know _whether_ there's a cause (and you don't care what it
-is), you can use `VError.hasCauseWithName(err, name)`.
-
-If a vanilla error or a non-VError error is passed in, then there is no cause
-chain to traverse. In this scenario, the function will check the `name`
-property of only `err`.
-
-### `VError.hasCauseWithName(err, name)`
-
-Returns true if and only if `VError.findCauseByName(err, name)` would return
-a non-null value.  This essentially determines whether `err` has any cause in
-its cause chain that has name `name`.
-
-### `VError.errorFromList(errors)`
-
-Given an array of Error objects (possibly empty), return a single error
-representing the whole collection of errors.  If the list has:
-
-* 0 elements, returns `null`
-* 1 element, returns the sole error
-* more than 1 element, returns a MultiError referencing the whole list
-
-This is useful for cases where an operation may produce any number of errors,
-and you ultimately want to implement the usual `callback(err)` pattern.  You can
-accumulate the errors in an array and then invoke
-`callback(VError.errorFromList(errors))` when the operation is complete.
-
-
-### `VError.errorForEach(err, func)`
-
-Convenience function for iterating an error that may itself be a MultiError.
-
-In all cases, `err` must be an Error.  If `err` is a MultiError, then `func` is
-invoked as `func(errorN)` for each of the underlying errors of the MultiError.
-If `err` is any other kind of error, `func` is invoked once as `func(err)`.  In
-all cases, `func` is invoked synchronously.
-
-This is useful for cases where an operation may produce any number of warnings
-that may be encapsulated with a MultiError -- but may not be.
-
-This function does not iterate an error's cause chain.
-
-
-## Examples
-
-The "Demo" section above covers several basic cases.  Here's a more advanced
-case:
-
-```javascript
-var err1 = new VError('something bad happened');
-/* ... */
-var err2 = new VError({
-    'name': 'ConnectionError',
-    'cause': err1,
-    'info': {
-        'errno': 'ECONNREFUSED',
-        'remote_ip': '127.0.0.1',
-        'port': 215
-    }
-}, 'failed to connect to "%s:%d"', '127.0.0.1', 215);
-
-console.log(err2.message);
-console.log(err2.name);
-console.log(VError.info(err2));
-console.log(err2.stack);
-```
-
-This outputs:
-
-    failed to connect to "127.0.0.1:215": something bad happened
-    ConnectionError
-    { errno: 'ECONNREFUSED', remote_ip: '127.0.0.1', port: 215 }
-    ConnectionError: failed to connect to "127.0.0.1:215": something bad happened
-        at Object.<anonymous> (/home/dap/node-verror/examples/info.js:5:12)
-        at Module._compile (module.js:456:26)
-        at Object.Module._extensions..js (module.js:474:10)
-        at Module.load (module.js:356:32)
-        at Function.Module._load (module.js:312:12)
-        at Function.Module.runMain (module.js:497:10)
-        at startup (node.js:119:16)
-        at node.js:935:3
-
-Information properties are inherited up the cause chain, with values at the top
-of the chain overriding same-named values lower in the chain.  To continue that
-example:
-
-```javascript
-var err3 = new VError({
-    'name': 'RequestError',
-    'cause': err2,
-    'info': {
-        'errno': 'EBADREQUEST'
-    }
-}, 'request failed');
-
-console.log(err3.message);
-console.log(err3.name);
-console.log(VError.info(err3));
-console.log(err3.stack);
-```
-
-This outputs:
-
-    request failed: failed to connect to "127.0.0.1:215": something bad happened
-    RequestError
-    { errno: 'EBADREQUEST', remote_ip: '127.0.0.1', port: 215 }
-    RequestError: request failed: failed to connect to "127.0.0.1:215": something bad happened
-        at Object.<anonymous> (/home/dap/node-verror/examples/info.js:20:12)
-        at Module._compile (module.js:456:26)
-        at Object.Module._extensions..js (module.js:474:10)
-        at Module.load (module.js:356:32)
-        at Function.Module._load (module.js:312:12)
-        at Function.Module.runMain (module.js:497:10)
-        at startup (node.js:119:16)
-        at node.js:935:3
-
-You can also print the complete stack trace of combined `Error`s by using
-`VError.fullStack(err).`
-
-```javascript
-var err1 = new VError('something bad happened');
-/* ... */
-var err2 = new VError(err1, 'something really bad happened here');
-
-console.log(VError.fullStack(err2));
-```
-
-This outputs:
-
-    VError: something really bad happened here: something bad happened
-        at Object.<anonymous> (/home/dap/node-verror/examples/fullStack.js:5:12)
-        at Module._compile (module.js:409:26)
-        at Object.Module._extensions..js (module.js:416:10)
-        at Module.load (module.js:343:32)
-        at Function.Module._load (module.js:300:12)
-        at Function.Module.runMain (module.js:441:10)
-        at startup (node.js:139:18)
-        at node.js:968:3
-    caused by: VError: something bad happened
-        at Object.<anonymous> (/home/dap/node-verror/examples/fullStack.js:3:12)
-        at Module._compile (module.js:409:26)
-        at Object.Module._extensions..js (module.js:416:10)
-        at Module.load (module.js:343:32)
-        at Function.Module._load (module.js:300:12)
-        at Function.Module.runMain (module.js:441:10)
-        at startup (node.js:139:18)
-        at node.js:968:3
-
-`VError.fullStack` is also safe to use on regular `Error`s, so feel free to use
-it whenever you need to extract the stack trace from an `Error`, regardless if
-it's a `VError` or not.
-
-# Reference: MultiError
-
-MultiError is an Error class that represents a group of Errors.  This is used
-when you logically need to provide a single Error, but you want to preserve
-information about multiple underying Errors.  A common case is when you execute
-several operations in parallel and some of them fail.
-
-MultiErrors are constructed as:
-
-```javascript
-new MultiError(error_list)
-```
-
-`error_list` is an array of at least one `Error` object.
-
-The cause of the MultiError is the first error provided.  None of the other
-`VError` options are supported.  The `message` for a MultiError consists the
-`message` from the first error, prepended with a message indicating that there
-were other errors.
-
-For example:
-
-```javascript
-err = new MultiError([
-    new Error('failed to resolve DNS name "abc.example.com"'),
-    new Error('failed to resolve DNS name "def.example.com"'),
-]);
-
-console.error(err.message);
-```
-
-outputs:
-
-    first of 2 errors: failed to resolve DNS name "abc.example.com"
-
-See the convenience function `VError.errorFromList`, which is sometimes simpler
-to use than this constructor.
-
-## Public methods
-
-
-### `errors()`
-
-Returns an array of the errors used to construct this MultiError.

-wide-align
-----------
-
-A wide-character aware text alignment function for use in terminals / on the
-console.
-
-### Usage
-
-```
-var align = require('wide-align')
-
-// Note that if you view this on a unicode console, all of the slashes are
-// aligned. This is because on a console, all narrow characters are
-// an en wide and all wide characters are an em. In browsers, this isn't
-// held to and wide characters like "古" can be less than two narrow
-// characters even with a fixed width font.
-
-console.log(align.center('abc', 10))     // '   abc    '
-console.log(align.center('古古古', 10))  // '  古古古  '
-console.log(align.left('abc', 10))       // 'abc       '
-console.log(align.left('古古古', 10))    // '古古古    '
-console.log(align.right('abc', 10))      // '       abc'
-console.log(align.right('古古古', 10))   // '    古古古'
-```
-
-### Functions
-
-#### `align.center(str, length)` → `str`
-
-Returns *str* with spaces added to both sides such that that it is *length*
-chars long and centered in the spaces.
-
-#### `align.left(str, length)` → `str`
-
-Returns *str* with spaces to the right such that it is *length* chars long.
-
-### `align.right(str, length)` → `str`
-
-Returns *str* with spaces to the left such that it is *length* chars long.
-
-### Origins
-
-These functions were originally taken from 
-[cliui](https://npmjs.com/package/cliui). Changes include switching to the
-MUCH faster pad generation function from
-[lodash](https://npmjs.com/package/lodash), making center alignment pad
-both sides and adding left alignment.

-# yallist
-
-Yet Another Linked List
-
-There are many doubly-linked list implementations like it, but this
-one is mine.
-
-For when an array would be too big, and a Map can't be iterated in
-reverse order.
-
-
-[![Build Status](https://travis-ci.org/isaacs/yallist.svg?branch=master)](https://travis-ci.org/isaacs/yallist) [![Coverage Status](https://coveralls.io/repos/isaacs/yallist/badge.svg?service=github)](https://coveralls.io/github/isaacs/yallist)
-
-## basic usage
-
-```javascript
-var yallist = require('yallist')
-var myList = yallist.create([1, 2, 3])
-myList.push('foo')
-myList.unshift('bar')
-// of course pop() and shift() are there, too
-console.log(myList.toArray()) // ['bar', 1, 2, 3, 'foo']
-myList.forEach(function (k) {
-  // walk the list head to tail
-})
-myList.forEachReverse(function (k, index, list) {
-  // walk the list tail to head
-})
-var myDoubledList = myList.map(function (k) {
-  return k + k
-})
-// now myDoubledList contains ['barbar', 2, 4, 6, 'foofoo']
-// mapReverse is also a thing
-var myDoubledListReverse = myList.mapReverse(function (k) {
-  return k + k
-}) // ['foofoo', 6, 4, 2, 'barbar']
-
-var reduced = myList.reduce(function (set, entry) {
-  set += entry
-  return set
-}, 'start')
-console.log(reduced) // 'startfoo123bar'
-```
-
-## api
-
-The whole API is considered "public".
-
-Functions with the same name as an Array method work more or less the
-same way.
-
-There's reverse versions of most things because that's the point.
-
-### Yallist
-
-Default export, the class that holds and manages a list.
-
-Call it with either a forEach-able (like an array) or a set of
-arguments, to initialize the list.
-
-The Array-ish methods all act like you'd expect.  No magic length,
-though, so if you change that it won't automatically prune or add
-empty spots.
-
-### Yallist.create(..)
-
-Alias for Yallist function.  Some people like factories.
-
-#### yallist.head
-
-The first node in the list
-
-#### yallist.tail
-
-The last node in the list
-
-#### yallist.length
-
-The number of nodes in the list.  (Change this at your peril.  It is
-not magic like Array length.)
-
-#### yallist.toArray()
-
-Convert the list to an array.
-
-#### yallist.forEach(fn, [thisp])
-
-Call a function on each item in the list.
-
-#### yallist.forEachReverse(fn, [thisp])
-
-Call a function on each item in the list, in reverse order.
-
-#### yallist.get(n)
-
-Get the data at position `n` in the list.  If you use this a lot,
-probably better off just using an Array.
-
-#### yallist.getReverse(n)
-
-Get the data at position `n`, counting from the tail.
-
-#### yallist.map(fn, thisp)
-
-Create a new Yallist with the result of calling the function on each
-item.
-
-#### yallist.mapReverse(fn, thisp)
-
-Same as `map`, but in reverse.
-
-#### yallist.pop()
-
-Get the data from the list tail, and remove the tail from the list.
-
-#### yallist.push(item, ...)
-
-Insert one or more items to the tail of the list.
-
-#### yallist.reduce(fn, initialValue)
-
-Like Array.reduce.
-
-#### yallist.reduceReverse
-
-Like Array.reduce, but in reverse.
-
-#### yallist.reverse
-
-Reverse the list in place.
-
-#### yallist.shift()
-
-Get the data from the list head, and remove the head from the list.
-
-#### yallist.slice([from], [to])
-
-Just like Array.slice, but returns a new Yallist.
-
-#### yallist.sliceReverse([from], [to])
-
-Just like yallist.slice, but the result is returned in reverse.
-
-#### yallist.toArray()
-
-Create an array representation of the list.
-
-#### yallist.toArrayReverse()
-
-Create a reversed array representation of the list.
-
-#### yallist.unshift(item, ...)
-
-Insert one or more items to the head of the list.
-
-#### yallist.unshiftNode(node)
-
-Move a Node object to the front of the list.  (That is, pull it out of
-wherever it lives, and make it the new head.)
-
-If the node belongs to a different list, then that list will remove it
-first.
-
-#### yallist.pushNode(node)
-
-Move a Node object to the end of the list.  (That is, pull it out of
-wherever it lives, and make it the new tail.)
-
-If the node belongs to a list already, then that list will remove it
-first.
-
-#### yallist.removeNode(node)
-
-Remove a node from the list, preserving referential integrity of head
-and tail and other nodes.
-
-Will throw an error if you try to have a list remove a node that
-doesn't belong to it.
-
-### Yallist.Node
-
-The class that holds the data and is actually the list.
-
-Call with `var n = new Node(value, previousNode, nextNode)`
-
-Note that if you do direct operations on Nodes themselves, it's very
-easy to get into weird states where the list is broken.  Be careful :)
-
-#### node.next
-
-The next node in the list.
-
-#### node.prev
-
-The previous node in the list.
-
-#### node.value
-
-The data the node contains.
-
-#### node.list
-
-The list to which this node belongs.  (Null if it does not belong to
-any list.)
