Python library for reading and writing OP files

[Åsmund Skjæveland <asmund skjaveland bio uio no>]

Is there a Python library for reading and writing PO files? I'm looking 
for something that will give me something like an object containing 
(msgids, msgstrs, isFuzzy, isObsolete) for each msgid (with plural 
support), and will write such strings to a PO file. As far as Google 
will tell me[1] there's not too much around, but I think what I'm 
looking for is hidden inside Pootle. Basically, is what I'm looking for 
available as a standalone module, or will I have to disassemble Pootle?

unhelpful.
