OPTIONS

18       halo accepts the following options:
19
20       --window
21               Draw on a newly-created window.  This is the default.
22
23       --root  Draw on the root window.
24
25       --window-id number
26               Draw on the specified window.
27
28       --mono  If on a color display, pretend we're on a monochrome display.
29
30       --install
31               Install a private colormap for the window.
32
33       --visual visual
34               Specify which visual to use.  Legal values are the  name  of  a
35               visual  class,  or the id number (decimal or hex) of a specific
36               visual.
37
38       --count integer
39               How many circles to draw.  Default 0, meaning random.
40
41       --mode seuss | ramp | random
42               In seuss mode, alternating striped curves will be drawn.
43
44               In ramp mode, a color ramp will be drawn.
45
46               random means pick the mode randomly.
47
48       --delay microseconds
49               How much of a delay should be introduced between steps  of  the
50               animation.  Default 100000, or about 0.1 second.
51
52       --colors integer
53               How many colors to use.  Default 100.
54
55       --animate
56               If  specified, then the centerpoints of the circles will bounce
57               around.  Otherwise, the circles will be drawn once, erased, and
58               a new set of circles will be drawn.
59
60       --fps   Display the current frame rate and CPU load.
