DESCRIPTION
       The hop program generates real plane fractals as	described in the  Sep-
       tember 1986 issue of Scientific American.

OPTIONS
       hopalong	accepts	the following options:

       -window Draw on a newly-created window.	This is	the default.

       -root   Draw on the root	window.

       -mono   If on a color display, pretend we're on a monochrome display.

       -install
	       Install a private colormap for the window.

       -visual visual
	       Specify	which  visual  to use.	Legal values are the name of a
	       visual class, or	the id number (decimal or hex) of  a  specific
	       visual.

       -ncolors	integer
	       How  many  colors  should  be used (if possible).  Default 200.
	       The colors used cycle through the hue, making  N	 stops	around
	       the color wheel.

       -cycles integer
	       How long	to run each batch.  Default 2500 pixels.

       -count integer
	       How many	pixels should be drawn before a	color change.  Default
	       1000.

       -jong integer

       -no-jong	integer
	       Whether to use the Jong format (default is to choose randomly.)

       -sine integer

       -no-sine	integer
	       Whether to use the Sine format (default is to choose randomly.)

       -fps    Display the current frame rate and CPU load.

ENVIRONMENT
       DISPLAY to get the default host and display number.

       XENVIRONMENT
	       to get the name of a resource file that	overrides  the	global
	       resources stored	in the RESOURCE_MANAGER	property.
