   SourceList - Manage a list of sources
   
   The Source List class provides access to a list of sources. It 
   can read them from a file and generate a list of all the distinct
   sources.
   
   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
   to be Acquired.
   
   The vendor machanism is similar, except the vendor types are hard 
   wired. Before loading the source list the vendor list is loaded.
   This doesn't load key data, just the checks to perform.
