   6    SourceList - Manage a list of sources
   7
   8    The Source List class provides access to a list of sources. It
   9    can read them from a file and generate a list of all the distinct
  10    sources.
  11
  12    All sources have a type associated with them that defines the layout
  13    of the archive. The exact format of the file is documented in
  14    files.sgml.
  15
  16    The types are mapped through a list of type definitions which handle
  17    the actual construction of the type. After loading a source list all
  18    you have is a list of package index files that have the ability
  19    to be Acquired.
