   Archive Extraction Directory Stream
   
   This Directory Stream implements extraction of an archive into the
   filesystem. It makes the choices on what files should be unpacked and
   replaces as well as guiding the actual unpacking.
   
   When the unpacking sequence is completed one of the two functions,
   Finished or Aborted must be called.
