Thanks, these are exactly what I need. Pickle is just the file format. 
The data are Python constructs, so I shouldn't have to bother with the 
format at all, since I'm simply converting the Pickled file into generic 
Python data. Plus, writing my own Pickle parser would be hugely 
complicated since Pickle is essentially its own small programming language.
