hals_end(6) outputs the last words of the supercomputer HAL 9000 aboard
the spaceship in Stanley Kubrick's famous film "2001 - A Space Odissey".
The source code and output of this program were used to illustrate
an article in the book "Total Interaction".  How this looks in print can
be at http://www.netbsd.org/~mbalmer/hals_end.jpg.
