   6    Archive Extraction Directory Stream
   7
   8    This Directory Stream implements extraction of an archive into the
   9    filesystem. It makes the choices on what files should be unpacked and
  10    replaces as well as guiding the actual unpacking.
  11
  12    When the unpacking sequence is completed one of the two functions,
  13    Finished or Aborted must be called.
