   /* KDiff3 can be used as replacement for the text-diff and merge tool provided by
      Clearcase. This is experimental and so far has only been tested under Windows.

      The installation is very simple:
      1. In the Clearcase "bin"-directory rename "cleardiffmrg.exe" to "cleardiffmrg_orig.exe".
      2. Copy kdiff3.exe into that "bin"-directory and rename it to "cleardiffmrg.exe".
         (Also copy the other files that are needed by KDiff3 there.)

      Now when a file comparison or merge is done by Clearcase then of course KDiff3 will be
      run instead.
      If the commandline contains the option "-directory" then KDiff3 can't do it but will
      run "cleardiffmrg_orig.exe" instead.
