    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 permutations.
+   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.
