Debian Archive File (.deb)
This Class handles all the operations performed directly on .deb
files. It makes use of the AR and TAR classes to give the necessary
external interface.
There are only two things that can be done with a raw package,
extract it's control information and extract the contents itself.
This should probably subclass an as-yet unwritten super class to
produce a generic archive mechanism.
The memory control file extractor is useful to extract a single file
into memory from the control.tar.gz
