In response to some of the recent activity around Python web frameworks, and some of the new interest in Paste, I thought it would be helpful to write a document about how you write a framework using WSGI. With RhubarbTart coming in at 302 lines (according to sloccount) I figure it's a pretty reasonable to consider writing your own. But really my hope is that this will make people more comfortable with this architectural style. Even if you don't write your own framework, it's nice to know both that you could write your own framework, and that you can probably understand the framework someone else writes, approaching it piece-by-piece.

So, here's the start: A Do-It-Yourself Framework. I still want to talk about configuration and deployment with Paste Deploy, and about packaging your application with setuptools and using entry points, but this is a good start.

Note that I haven't tested the examples. Bad me. Testing tires me out sometimes.
