   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 type. After loading a source list all
   you have is a list of package index files that have the ability
   to be Acquired.
