It doesn't do nearly everything one might want, but it does do some
things you might want and some other things you might not know you want.

Optional is one of those libraries that's just a good idea.

FWIW last time I needed some option processing I grabbed Aaron

If anyone wants to keep hacking the code is here...

You can also use Java APIs. I use joptsimple, for instance.
