joachim99@69:       -  The file lib/mgrs/map contains the list of compare/merge tasks on one side and

joachim99@69:          edit this file and put kdiff3 there instead. (Recommended method)
joachim99@69:       -  Exchange the original program with KDiff3: (Hackish, no fine control)
joachim99@69:          1. In the Clearcase "bin"-directory rename "cleardiffmrg.exe" to "cleardiffmrg_orig.exe".
joachim99@69:          2. Copy kdiff3.exe into that "bin"-directory and rename it to "cleardiffmrg.exe".
joachim99@69:             (Also copy the other files that are needed by KDiff3 there.)
joachim99@69:          Now when a file comparison or merge is done by Clearcase then of course KDiff3 will be
joachim99@69:          run instead.
joachim99@69:          If the commandline contains the option "-directory" then KDiff3 can't do it but will
joachim99@69:          run "cleardiffmrg_orig.exe" instead.
