+cdif is a post-processor of the Unix diff command.  It highlights
+deleted, changed and added words based on word context.  You may want
+to compare character-by-character rather than word-by-word.  Option -B
+option can be used for that purpose.  If only one file is specified,
+cdif reads that file (stdin if no file) as a output from diff command.
+Lines those don't look like diff output are simply ignored and
+printed.
+
+Note that this requires fdescfs(5) mounted.
