[Pythonmac-SIG] running Cocoa application from python

[Roger Herikstad]

Hi,
 Thanks for your quick reply. I'm leaning towards case 2 i) as it
seems the simpler. You are quite right in that speed is an issue for
me, so I'll have to do some testing to see what suits my needs. I
guess as long as I have access to the python interpreter, it might as
well be from within the application itself. Thanks again!
