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')
