+
+   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.
