* Application quitting code, using Apple Events and Process Manager. I took
* this straight out of an earlier program dated 28 December 1992. I've violated
* my own copyright. Darn. I think I'll sue.
*
* I guess it just goes to show how out of touch I am with Mac programming that
* I still consider Apple Events and the Process Manager "new". whoo. I guess I
* quit learning when they quit sending me those free Developer CDs. :)
*
* One of the more significant improvements that could be made to this code
* would be to run indent over it. The other would be to change all the variable
* names to 'foo' with various random numbers appended. A somewhat less important
* problem is that of error checking, because Allen said, "Don't stop the boot when
* things go wrong." (Obviously Allen does not work for Saturn. heh... :)
