Seems that it should be stressed that this might not work for developer's that make use of a GIT GUI. It's usage assumes the command line. Or am I wrong? Issue I see is this forces all developers working on the code to work only with GIT commands, on the command line. I bounce back and forth, because conflicts and logs are faster for me in smartGit. But this breaks commits in smartGit.

On the other hand, could this not be updated to deal with git GUI's?
