+
+   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
+
