Index File - Abstraction for an index of archive/source file.
Binary index files
Binary translation files
- Bianry index files decribing the local system
+ Binary index files describing the local system
Source index files
They are all bundled together here, and the interfaces for
sources.list, acquire, cache gen and record parsing all use this class
- to acess the underlying representation.
