i have a script that reads django models.py files and constructs OmniGraffle object models. hmm...could be neat to go the other way since i usually make the diagrams first...i wrote the script because once the main idea is figured out then i'll make lots of iterative changes in the code and not want to update the diagram so carefully..

i'm still working out the details. but i'll post here as soon as that's all good :-) not sure if anyone else is interested, i guess.
