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.
