2 Draw real plane fractals
6 $ hopalong [-display host:display.screen] [-foreground color]
7 [-background color] [-window] [-root] [-mono] [-count integer]
8 [-ncolors integer] [-timeout seconds] [-delay microseconds]
11 The hopalong program generates real plane fractals as described in
12 the September 1986 issue of Scientific American.
15 hopalong accepts the following options:
18 Draw on a newly-created window. This is the default.
21 Draw on the root window.
24 If on a color display, pretend we're on a monochrome display.
27 How many pixels should be drawn before a color change. Default 1000.
30 How many colors should be used (if possible). Default 100.
31 The colors used cycle through the hue, making N stops around
35 How many seconds we should generate for before clearing the screen
36 and starting over. Default 20.
39 How long we should wait between drawing each pixel. Default 0.
44 to get the default host and display number.
47 to get the name of a resource file that overrides the global resources
48 stored in the RESOURCE_MANAGER property.
