Don't get upset, guys.
This is one of several demo-scripts in Emacs. There is also an Eliza-like psychologist program and a towers of Hanoi game in there. These are part of the Emacs package so they had to be included, though they originate in the open-source unix world, not with Apple. Emacs is a popular editor with many Unix administrators and leaving it out would have been a mistake.
And they occupy about as much space as ten-seconds of MP3 sound, so who cares?
