   Package Records - Allows access to complete package description records
                     directly from the file.
   
   The package record system abstracts the actual parsing of the 
   package files. This is different than the generators parser in that
   it is used to access information not generate information. No 
   information touched by the generator should be parable from here as
   it can always be retreived directly from the cache.
