I use it frequently and I like the output it creates. I sure as hell like python's better than C#'s (== none at all and people doing all kinds of crazy broken crap inlined into Main(string[] args).

I've never managed to use optparse without the docs open though. I'm not sure that's a defect, but it seems like room for improvement.

Can someone (zed?) point at a library in any other language that's better?
