The fretsonfire source package has to be rebuilt to deal with a few DFSG
problems:

   1. The songs supplied with the game are not DFSG (no separate redistribution
      or modification). These have been removed.
   2. The fonts supplied are not Open. These have been removed. They are
      replaced by symlinks to other packages in debian/rules

Other things which are done:

   - turn off the executable bit on files (probably uploaded from windows)

The dfsg source can be obtained from debian/rules get-orig-source.
