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