'commandline' and 'choice' are two gems that do what you want. 'commandline'
is powerful, and based on the optparse library, but its documentation leaves
a lot to be desired. The basic README gets you started but you have to
deduce a lot for complex arguments.

'choice' is more constrained, and easier to use, but it doesn't work too
well when things get complex. Its great for simple sets of name-value pairs,
though. The developer also seems responsive to bugs and feedback. At least,
he fixed the one bug I sent in :)

Commandline: http://rubyforge.org/projects/optionparser/
Choice: http://rubyforge.org/projects/choice/
