+
+   Directory Stream 
+
+   When unpacking the contents of the archive are passed into a directory
+   stream class for analysis and processing. The class controls all aspects
+   of actually writing the directory stream from disk. The low level
+   archive handlers are only responsible for decoding the archive format
+   and sending events (via method calls) to the specified directory
+   stream.
+   
+   When unpacking a real file the archive handler is passed back a file 
+   handle to write the data to, this is to support strange 
+   archives+unpacking methods. If that fd is -1 then the file data is 
+   simply ignored.
+   
+   The provided defaults do the 'Right Thing' for a normal unpacking
+   process (ie 'tar')
