pyvcs is a minimal VCS abstraction layer for Python. It's goals are to provide as much functionality as is necessary, and no further. It doesn't try to abstract every layer or feature of a VCS, just what's necessary to build a code browsing UI.
Currently supported VCS backends are::
* Mercurial
* Git
* Subversion
* Bazaar
Requirements::
* Python (2.4 or greater)
Backend Specific Requirements::
* Git
* Dulwich (http://github.com/jelmer/dulwich/)
* Subversion
* Pysvn (http://pysvn.tigris.org/)
