* The format is proprietary and isn't likely to be opened soon.
* The only program to decompress unace files is outdated, is usually
  offered in binary-only form and is even more outdated for non-Linux
  platforms (think BSD here).
* This program is _really_ horrible and does awful things like trimming
  the file names in its listings, making it impossible to use with
  cliinterface.
* This program doesn't allow the user to create ace files.
Just disabling it in the source tree would mean having unmaintained code
forever (since things aren't likely to change regarding the format).
