Diffuse is an open source graphical tool for merging and comparing text files.
Diffuse is able to compare an arbitrary number of files side-by-side and offers the ability to manually adjust line-matching and directly edit files. Diffuse can also retrieve revisions of files from bazaar, CVS, darcs, git, mercurial, monotone, Subversion and GNU Revision Control System (RCS) repositories for comparison and merging.
Diffuse is implemented entirely in Python and should run on any platform with Python and PyGTK.
