	6	Index File - Abstraction for an index of archive/source file.
	7
	8	There are 4 primary sorts of index files, all represented by this
	9	class:
	10
	11	Binary index files
	12	Binary translation files
	13	Bianry index files decribing the local system
	14	Source index files
	15
	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 acess the underlying representation.
