Here is a map (
pdf) that I've just drawn to try to clarify the dependencies between the
so-called frameworks and "megaframeworks" and other Python packages.

I have tried to cover, so far:

  • Zope (w/ CPS as an example of a framework built on top of Zope)

  • TurboGears

  • Django

  • Subway

  • Pylons

Feel free to comment. I'm probably wrong in many places. (Even the CPS part
may be wrong ;) ).
