6 Index File - Abstraction for an index of archive/source file.
8 There are 3 primary sorts of index files, all represented by this
12 Bianry index files decribing the local system
15 They are all bundled together here, and the interfaces for
16 sources.list, acquire, cache gen and record parsing all use this class
17 to acess the underlying representation.
