GUI applications do not generally take command line arguments.

Except that the file is not passed on the command line. Instead, it is
handed an 'odoc' AppleEvent.

You're assuming that opened files are passed as arguments. They're
not. The method for handling these events in Cocoa is to implement the
relevant delegate methods in NSApplication.
