optparse/argparse for cgi/wsgi?

[samwyse]

Has anyone ever built some sort of optparse/argparse module for cgi/
wsgi programs?  I can see why a straight port wouldn't work, but a
module that can organize parameter handling for web pages seems like a
good idea, especially if it provided a standard collection of both
client- and server-side validation processes, easy
internationalization, and a way to create customizable help pages.
