Python megaframeworks concept map

Here is a map ( png, 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 ;) ).
