Zachary on Routes with CherryPy
Zachary.com has a very nice update on Routes with CherryPy covering not only how to integrate them, but why you'd want to use Routes style dispatch instead of the object publishing approach CherryPy uses by default.
In the future, there'll also be an independent dispatcher for Routes that handles dispatch at the WSGI level. I believe Ian Bicking already has such code, though he hasn't released it yet. I'm sure it'd make a great Part 2 in his series(?) on working with WSGI up close and personal. If you haven't read his Do-It-Yourself Framework, I'd highly suggest giving it a read.
Not only does it help demystify WSGI, but it should hopefully make it more obvious why WSGI is changing the point of competition in the world of web programming.
