Pygame Extended, a game programming framework
Pygame Extended (or pygext) is a framework for game development. It has a lot of miscellanous libraries to expand Pygame, but the heart of the framework is the pygext.gl package, that provides an easy to use, OpenGL accelerated sprite/event-engine.
See http://codereactor.net/projects/pygext/apidoc/index.html for full listing of contents and the wiki at http://trac.codereactor.net/pygext for more information.
NOTE: this release of pygext is still alpha, so there will be backward incompatible API changes and refactoring in future versions.
