Parsing Java command-line arguments

From Arnout Engelen

It'd be nice to have a lib that:

• automatically generates 'usage' information and nice error messages
• doesn't require casting and supports sufficient data types
  • strings
  • numbers
  • dates
  • lists
• supports default values

Haven't found such a lib yet.

Options:

• jopt-simple.sf.net - no default values, support for dates cumbersome.
• jewelcli.sf.net - inelegant optional options, no times/dates
  • please could you submit a feature request with more details on your requirements?
