+      Clearcase. This is experimental and so far has only been tested under Windows.
+
+      There are two ways to use KDiff3 with clearcase
+      -  The file lib/mgrs/map contains the list of compare/merge tasks on one side and 
+         the tool on the other. Originally this contains only clearcase tools, but you can
+         edit this file and put kdiff3 there instead. (Recommended method)
+      -  Exchange the original program with KDiff3: (Hackish, no fine control)
+         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.
