An application *should* do only its "we'll do this stuff every time" 
initialization when it starts up, then wait for the first Apple event.

That event will be
   oapp      "you were started by double-clicking your icon"
   odoc      "you were started by having these docs opened or dragged
                   onto you"
   pdoc      "you were started by having these docs printed"
   noop      "none of the above:  you're on your own"

(or anything else another app in a suite of apps passes to 
LaunchApplication to be used as the initial Apple event...that's a 
matter of agreement among the applications involved).
