52 XMountains generates realistic-looking fractal terrains of snow-capped
53 mountains near water, with either a top view or a side view. Written
54 by Stephen Booth. This is not included with the XScreenSaver package,
55 but if you don't have it already, you can find it at
56 <http://www.epcc.ed.ac.uk/~spb/xmountains/>.
58 Be sure to compile it with -DVROOT or it won't work right when launched
59 by the xscreensaver daemon.
