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.
