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 back end type. After loading a source
18 list all you have is a list of package index files that have the ability
19 to be Acquired.
20
21 The vendor machanism is similar, except the vendor types are hard
22 wired. Before loading the source list the vendor list is loaded.
23 This doesn't load key data, just the checks to perform.
