-.SH DESCRIPTION
-The \fIwhirlygig\fP program draws a series of circles on your screen.
-They then move about in a cyclic pattern
-.SH OPTIONS
-.I whirlygig
-accepts the following options:
-.TP 8
-.B \-window
-Draw on a newly-created window. This is the default.
-.TP 8
-.B \-root
-Draw on the root window.
-.TP 8
-.B \-visual \fIvisual\fP
-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.
-.TP 8
-.B \-xspeed \fIspeed\fP
-Specify how fast the dots should cycle horizontally.
-Try out values from .01 to 4000. Defaults to 1.0.
-.TP 8
-.B \-yspeed \fIspeed\fP
-Specify how fast the dots should cycle vertically.
-Try out values from .01 to 4000. Defaults to 1.0.
-.TP 8
-.B \-xamplitude \fIfactor\fP
-Specify the horizontal amplitude.
-Try out values from .01 to 10. Defaults to 1.0.
-.TP 8
-.B \-yamplitude \fIfactor\fP
-Specify the horizontal amplitude.
-Try out values from .01 to 10. Defaults to 1.0.
-.TP 8
-.B \-whirlies \fIa number\fP
-Specify how many whirlies you want (per line). Defaults
-to a random number.
-.TP 8
-.B \-nlines \fInumber of lines\fP
-Specify how many lines of whirlies you want. Defaults to a
-random number.
-.TP 8
-.B \-xmode \fImode\fP
-.TP 8
-.B \-ymode \fImode\fP
-Specify which mode to use for calculating the x and y positions of the
-whirlies. Can be any of spin, funky, circle, linear, test, fun, innie
-or lissajous. Defaults to 'change' mode, which randomly selects a new
-mode for x and y every now an then. Unrecognized options default to spin.
-.TP 8
-.B \-explain
-Prints some strings to the window explaining what the initially
-selected modes are, before displaying the whirlies. Off by default.
-.TP 8
-.B \-trail \fI1 or 0\fP
-Trail mode fails to erase the whirlies as they move, so they leave a
-multicoloured trail behind. Doesn't work if the doubled buffered mode
-is using the X server's double buffer extension, and the useDBEclear
-resource is true (which it is by default).
-.TP 8
-.B \-speed \fIint\fP
-Specifies how fast to cycle through the internal time. Values 1,2 and
-3 look ok, up to 10 is not too bad, but beyond ends up
-flickery. Adjust xspeed and yspeed instead.
-.TP 8
-.B \-start_time \fIint\fP
-Where in the internal time cycle to start. Ranges from 1 to 429496729,
-Defaults to a random value.
-.TP 8
-.B \-xoffset \fIfactor\fP
-Tell the whirlies to be offset by this factor of a sin.
-Defaults to 1.0
-.TP 8
-.B \-yoffset \fIfactor\fP
-Tell the whirlies to be offset by this factor of a cos.
-Defaults to 1.0
-.TP 8
-.B \-offset_period \fIfactor\fP
-Change the period of an offset cycle
-Defaults to 1
-.TP 8
-.B \-color_modifier \fIint\fP
-How many colors away from the current should the next whirly be?
-.TP 8
-.B \-wrap \fI1|0\fP
-Causes whirlies that fall off the edge of the screen to wrap over to
-the other end of the screen. Otherwise they disappear and new ones
-to materialize on the other side of the screen. The difference is
-subtle, but it is different. Try it. On by default.
-.TP 8
-.B \-db
-.TP 8
-.B \-no-db
-Use double buffering to reduce flicker. This uses the double buffering
-extension if your X server supports it, otherwise it draws to it's own
-pixmap buffer and copies that to the window, which works almost as
-well. If the resource 'useDBEClear' is true, whirlies are not
-individually erased, so the -trail option won't work, and running
-multiple instances on the root window will flicker.
-
-.TP 8
-.B \-fps
-Display the current frame rate and CPU load.
-.SH ENVIRONMENT
-.PP
-.TP 8
-.B DISPLAY
-to get the default host and display number.
-.TP 8
-.B XENVIRONMENT
-to get the name of a resource file that overrides the global resources
-stored in the RESOURCE_MANAGER property.
