Oh - maybe the intent is that we are supposed to unrar these files, and
diff the contents of the uncompressed files? Sorry, but rar is not a
free format (free-of-charge programs is not the same as software that
respects user freedoms). The GNU unrar cannot uncompress rar3 archives,
so it is difficult for free software developers to get at your original
contents. Can you please use a free compression format (such as gzip)
instead of the patent-encumbered rar for posting the files you are
discussing?
