Hi Eric,

Yes, there's a whole option-parsing system called 'optparse' that handles
option-parsing and the -h documentation generator:

    http://www.python.org/doc/lib/module-optparse.html

The examples in the documentation there should help you get started.


If you have more questions, though, please feel free to ask.  Good luck!
