+   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.
