+   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.
