What is GitX?
GitX is an OS X (MacOS) native graphical client for the git version
control system.
GitX has a long history of various branches and versions maintained by various people over the years. This github org & repo are an attempt to consolidate and move forward with a current, common, community-maintained version. See discussion at Forking, and plans for the future of GitX.
