	6	Index File - Abstraction for an index of archive/source file.
	7
	8	There are 3 primary sorts of index files, all represented by this
	9	class:
	10
	11	Binary index files
	12	Bianry index files decribing the local system
	13	Source index files
	14
	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.
