This program animates a bunch of little line segments chasing a randomly
accelerating line segment.  The concept is simple, but the effect is pretty
cute.  By default, it comes up in a window, but it can be put in the root
window too.  In order to make it usable as a screen background, you can
alter the delay between updates, making it use very little cpu time.  One of
the reasons why it doesn't use much cpu time is that it only uses integer
arithmetic.

This program has been tested successfully on a Sun4, a DECStation 3100, and
a Stardent Titan.  The 3100 and the Titan were running X11R3 and the Sun4
was running X11R4.

The only thing you will probably have to change in the Makefile is the
location of X include files.  Sorry for the lack of an Imakefile, but imake
on all of the systems I have access to is installed improperly.

Try xswarm -h for help.  Fiddle with the parameters.  You can get really
different effects!
