This is the Hg-Git plugin for Mercurial, adding the ability to push to and pull from a Git server repository from Mercurial. This means you can collaborate on Git based projects from Mercurial, or use a Git server as a collaboration point for a team with developers using both Git and Mercurial. Warning, this software is still beta. It is basically feature complete and pretty stable now, but there are still some edge cases that aren't handled well yet and it may be slow in some circumstances. The user interface is also still subject to change.
