SYNOPSIS
       halo  [-display	host:display.screen]  [-foreground color] [-background
       color] [-window]	[-root]	[-mono]	[-install]  [-visual  visual]  [-count

DESCRIPTION
       The halo	program	draws cool patterns based on circles.

OPTIONS
       halo 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.

       -count integer
	       How many	circles	to draw.  Default 0, meaning random.

       -mode seuss | ramp | random
	       In seuss	mode, alternating striped curves will be drawn.

	       In ramp mode, a color ramp will be drawn.

	       random means pick the mode randomly.

       -delay microseconds
	       How much	of a delay should be introduced	between	steps  of  the
	       animation.  Default 100000, or about 0.1	second.

       -colors integer
	       How many	colors to use.	Default	100.

       -animate
	       If  specified, then the centerpoints of the circles will	bounce
	       around.	Otherwise, the circles will be drawn once, erased, and
	       a new set of circles will be drawn.

       -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.
