Nopt is a great tool for option parsing, but I miss a show usage message generator.

I've implemented a very simple one on top of nopt. I hope you will find it useful.

It doesn't change the behaviour of the rest of nopt, and it was implemented in a separate file.

This pull request also solve #7.

Cheers

Do you prefer that I publish this feature in npm ?
The name could be nopt-usage.

Doing this as a separate module would be better.
