6 Index File - Abstraction for an index of archive/source file.
8 There are 4 primary sorts of index files, all represented by this
12 Binary translation files
13 Binary index files describing the local system
16 They are all bundled together here, and the interfaces for
17 sources.list, acquire, cache gen and record parsing all use this class
18 to access the underlying representation.
