I'm surprised there isn't any info about this on the wiki page.
Basically, your app won't start receiving AppleEvents until it's
fully started, so you won't get a MacOpenFile notification. However,
if you drag a file onto an app to start it, you will receive the
filename of the dragged file in the app's command line arguments, so
you need to parse sys.argv, pull out the filename, and load it that way.
