There's a better one (in my obviously biased opinion): Mono.GetOptions.
See the attached file for an example. It's unique in the option-parsing
world (AFAIK) in that it uses attributes to specify the help text,
short, and long flags that are interpreted.
The one thing I can't figure out is how to specify "verbosity levels",
where "-v -v -v" would be a valid set of command line arguments...
