Thor is a simple and efficient tool for building self-documenting command line utilities. It removes the pain of parsing command line options, writing "USAGE:" banners, and can also be used as an alternative to the Rake build tool. The syntax is Rake-like, so it should be familiar to most Rake users.
gem install thor
