    All sources have a type associated with them that defines the layout
    of the archive. The exact format of the file is documented in
    files.sgml.

+   The types are mapped through a list of type definitions which handle
+   the actual construction of the back end type. After loading a source 
+   list all you have is a list of package index files that have the ability
