+
+ 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')
