       The  goal  of nerverot is to be interesting and compelling to watch, yet induce a state of
       nervous edginess in the viewer. This manpage describes v1.3 of the program.

       nerverot accepts the following options:

       -window Draw on a newly-created window.	This is the default.

       -root   Draw on the root window.

       -mono   If on a color display, pretend we're on a monochrome display.

	       Install a private colormap for the window.

       -visual visual
	       Which visual to use.  Legal values are the name of a visual class, or the id  num-
	       ber (decimal or hex) of a specific visual.

       -db     -no-db  Use  double-buffering  (or  not,  respectively). Double-buffering may make
	       things look better for larger line widths and/or  larger  numbers  of  blots,  but
	       "better"  may  equate  to  yielding less of the desired edginess effect. You'll be
	       calmer after watching the double-buffered variant; you're more likely to  go  into
	       epileptic  fits with it off. Hence, it is off (false) by default, resource double-

       -colors integer
	       How many colors should be used (if  possible).  The  colors  form  a  smooth  ramp
	       between two randomly-chosen colors. Defaults to 4, resource colors.

       -delay microseconds
	       The interframe delay, in microseconds. Defaults to 10000, resource delay.

       -max-iters integer
	       The  maximum  number  of  iterations (frames) before a new model is generated. The
	       actual number of iterations per model is a random number between 1 and this value.
	       Defaults to 1200, resource maxIters.

       -count integer
	       How  many  "blots"  to  draw at a time. This number may be rounded down to fit the
	       particularly chosen model, and has a fixed minimum per-model.   Defaults  to  250,
	       resource count.

       -line-width integer
	       The  width  of the lines to draw. 0 means an optimized pixel-thick line.  Defaults
	       to 0, resource lineWidth.

       -event-chance fraction
	       The chance, per iteration, for a life-altering event to occur (such as  picking	a
	       new rotation target), in the range 0..1. Defaults to 0.2, resource eventChance.

       -iter-amt fraction
	       The  fraction  of movement towards a target (such as rotation angle or scale) that
	       happens per iteration, in the range 0..1. Defaults to 0.01, resource terAmt.

       -nervousness fraction
	       How nervous the drawing is, in the range 0..1. This is how  jumpy  the  points  on
	       each blot are. Defaults to 0.3, resource nervousness.

       -max-nerve-radius fraction
	       The  maximum  radius of blot nervousness, as a fraction of the radius of the blot,
	       in the range 0..1. Defaults to 0.7, resource maxNerveRadius.

       -min-radius integer
	       The minimum radius for a blot, in the range 1..100. Defaults to 3, resource minRa-

       -max-radius integer
	       The  maximum  radius  for  a  blot,  in the range 1..100. Defaults to 25, resource

       -min-scale fraction
	       The minimum overall scale of  drawing,  as  a  fraction	of  min(windowHeight,win-
	       dowWidth), in the range 0..10. Defaults to 0.6, resource minScale.

       -max-scale fraction
	       The  maximum  overall  scale  of  drawing,  as a fraction of min(windowHeight,win-
	       dowWidth), in the range 0..10. Defaults to 1.75, resource maxScale.

       DISPLAY to get the default host and display number.

	       to get the name of a resource file that overrides the global resources  stored  in
	       the RESOURCE_MANAGER property.

       There are resource equivalents for each option, noted above.

       nerverot should have more models.

       XDBE should be detected and used, if available.
