user interface - Graphical DIFF programs for linux
I really like Araxis Merge for a graphical DIFF program for the PC. I have no idea what's available for linux, though.  We're running SUSE linux on our z800 mainframe.
I'd be most grateful if I could get a few pointers to what programs everyone else likes.

I know of two graphical diff programs: Meld and KDiff3. I haven't used KDiff3, but Meld works well for me.
It seems that both are in the standard package repositories for openSUSE 11.0
