    (description "GNU XaoS is a graphical program that generates fractal patterns and
allows you to zoom in and out of them infinitely in a fluid, continuous
manner.  It also includes tutorials that help to explain how fractals are
built.  It can generate many different fractal types such as the Mandelbrot
set.")
