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.
