10 The halo program draws cool patterns based on circles.
13 halo accepts the following options:
16 Draw on a newly-created window. This is the default.
19 Draw on the root window.
22 If on a color display, pretend we're on a monochrome display.
25 How many circles to draw. Default 0, meaning random.
28 How much of a delay should be introduced between steps of the animation.
29 Default 100000, or about 0.1 second.
32 If specified, then the centerpoints of the circles will bounce around.
33 Otherwise, the circles will be drawn once, erased, and a new set of
34 circles will be drawn.
39 to get the default host and display number.
42 to get the name of a resource file that overrides the global resources
43 stored in the RESOURCE_MANAGER property.
