Like we can setup our own text editor in the developer data (I like sublime text 2 and currently am developing a Baan grammar for it), I would like to specify what Merge/Diff tool I want to use to view differences between versions of a file.

Also, RCS is 30 years old and not well suited for concurrent development on the same files. Is there anyway we can use a modern version control system like Git, or at least Subversion?
