    // alassian-connect-express currently integrates with JugglingDB for persistence
    // to store the host client information (i.e., client key, host public
    // key, etc). When no adapter is specified, it defaults to JugglingDB's
    // fallback memory storage.
    //
    // To specify a backend for JugglingDB other than "memory", set the
    // "type" value to one of Juggling's other supported types.  See
    // https://github.com/1602/jugglingdb for more information.
    //
    // To use your own storage adapter, add the key
    // "adapter" to the following configuration, and replace "type" and
    // "connection" with any values your adapter expects.  Then make sure
    // that you register your adapter factory with the following code in
    // app.js:
    //
    //   ac.store.register(adapterName, factoryFn)
    //
    // See atlassian-connect-express/lib/store/index.js and the default jugglingdb.js
    // files for code demonstrating how to write a conformant adapter.  The
    // default values are as follows:
    //
    //   "store": {
    //     "adapter": "jugglingdb",
    //     "type": "memory"
    //   },
    //
    // To instead configure, say, a PostgreSQL store, the following could be
    // used:
    //
    //   "store": {
    //     "adapter": "jugglingdb",
    //     "type": "postgres",
    //     "url": "postgres://localhost/my_addon_database"

  // the NODE_ENV=production environment variable.
