+None known, probably many. Valgrind does not complain though.
+
+.SH "WISH LIST"
+
+The format of the output should definitely be improved. Not clear how.
+
+The comparison algorithm could definitely use some MD5 kind of
+signature. I doubt it would really speed up a lot.
+
+Their should be some fancy option to run two instances of the command
+on different machines so that comparison could be done without disk
+access where the disk are physically.
