Pygame Extended, a game programming framework
Pygame Extended (or pygext) is a collection of libraries for Pygame development. It contains, for example, additions to pygame.draw (e.g. rectangles with round corners), an opengl accelerated 2D vector graphics library and a full blown, event-based sprite/scene engine.
See http://codereactor.net/projects/pygext/apidoc/index.html for full listing of contents.
NOTE: pygext is in the alpha stages, so there will still be backward incompatible API changes and refactoring.
