From the developer:
RabbitVCS is a set of graphical tools written to provide simple and straightforward access to the version control systems you use. Currently, it is integrated into the Nautilus and Thunar file managers, the Gedit text editor and supports Subversion and Git, with a goal to incorporate other version control systems as well as other file managers.
