8 The \fIhalo\fP program draws cool patterns based on circles.
11 accepts the following options:
14 Draw on a newly-created window. This is the default.
17 Draw on the root window.
20 If on a color display, pretend we're on a monochrome display.
23 Install a private colormap for the window.
25 .B \-visual \fIvisual\fP
26 Specify which visual to use. Legal values are the name of a visual class,
27 or the id number (decimal or hex) of a specific visual.
29 .B \-count \fIinteger\fP
30 How many circles to draw. Default 0, meaning random.
32 .B \-mode "seuss | ramp | random"
33 In \fIseuss\fP mode, alternating striped curves will be drawn.
35 In \fIramp\fP mode, a color ramp will be drawn.
37 \fIrandom\fP means pick the mode randomly.
39 .B \-delay \fImicroseconds\fP
40 How much of a delay should be introduced between steps of the animation.
41 Default 100000, or about 0.1 second.
43 .B \-colors \fIinteger\fP
44 How many colors to use. Default 100.
47 If specified, then the centerpoints of the circles will bounce around.
48 Otherwise, the circles will be drawn once, erased, and a new set of
49 circles will be drawn.
54 Whether to do colormap cycling. Default is to cycle.
57 Number of microseconds between shifts of the colormap; default 100000,
63 to get the default host and display number.
