You probably won't want to actually merge this, as I didn't test it, and didn't update README, but here's some other stuff unscripted provides that you can take advantage of: Type annotating parameters with types that have a static `parse` method will automatically use that to validate and parse the argument, and display an error and help text if an invalid value was passed. So in this case `int.parse` and `double.parse` will be used. `allowed` specifies the allowed values of an option, which will also display an error on an invalid value, and will show up in the help. Can pass a List or a Map from values to help text for each value. Either type annotating an option as a List, or specifying `allowMultiple` will mean you can specify option multiple times on the command line, and they will be passed to the function as a List. I filed a bug for unscripted to support comma separated values: seaneagan/unscripted#49

@seaneagan - thanks so much! I had originally tried with int/double but get the following error whenever I try: |

Ah, they removed a feature from dart:mirrors that I was using. Fixed in unscripted 0.3.2: http://pub.dartlang.org/packages/unscripted Thanks! |
