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.

+.Sh NAME
+.Nm hals_end
+.Nd Display HAL's last words on the console
+.Sh SYNOPSIS
+.Nm hals_end
+.Op Fl f
+.Sh DESCRIPTION
+.Nm
+displays the famous last words of the supercomputer HAL 9000 aboard the
+space-ship in Stanley Kubrick's movie "2001 - A Space Odissey".
+.Pp
+Options:
+.Bl -tag -width Ds
+.It Fl f
+Fast forward.
+Every movie can be played back with fast forward.
+This option will double the speed of the output.
+.El
+.Sh BUGS
+Unlike the real HAL, this program can be repeately run.
+There should be functionality in the program to destroy itself after one run.
+The rationale for not doing this right now is that the movie itself can be
+watched several times as well.
+.Sh HISTORY
+.Nm
+first appeared in the book "Total Interaction" (ISBN 978-3-7643-7076-3) where
+it's source code and output illustrates the article
+"Remembering the Future: Memory and Interaction" by Dr. Regine Halter.
+The source code was set in contrast to the graphical artwork "HAL's lifespace"
+by Catherine Walthard.
+"HAL's Lifespace" and "hals_end" were respectively designed and written for
+this article.
+.Sh AUTHORS
+.Nm
+was written by
+.An Marc Balmer Aq Mt marc@msys.ch .
