/* ######################################################################
Index File - Abstraction for an index of archive/source file.
There are 4 primary sorts of index files, all represented by this
class:
Binary index files
Binary translation files
Binary index files describing 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 access the underlying representation.
