I'm trying to make a set of scripts that will go back and forth between Classical Mac OS and OS X, using the Carbon Python. Now I have some questions: #1: Is there a way to tell what version of 'mac' I'm on? os.name() doesn't help much... ;) #2: Assuming I'm on X, is there a way to execute command-line programs? I found posix.execve(), but does this work on OS X?
