Trollop is designed to provide the maximal amount of GNU-style argument processing in the minimum number of lines of code (for you, the programmer). - Simple usage. - Sensible defaults. No tweaking necessary, much tweaking possible. - Support for long options, short options, short option bundling, and automatic type validation and conversion. - Support for subcommands. - Automatic help message generation, wrapped to current screen width. - Lots of unit tests.
