Michael Foord (aka Fuzzyman aka @voidspace) has kindly jumpstarted the task of porting the Python Testing Tools Taxonomy (aka PTTT) to reStructuredText, and to put it up on bitbucket for easier collaboration. The new bitbucket project is called taxonomy. Michael ported the unit testing section so far.
Porting the original trac format to reST is not the most fun way to spend one's time, so we need collaborators. If you're interested in contributing to this project, please fork and let us know so we can commit your patches. Thanks!
