+ Index File - Abstraction for an index of archive/source file.
+
+ There are 3 primary sorts of index files, all represented by this
+ class:
+
+ Binary index files
+ Bianry index files decribing 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.
