       pinion - draws a scrolling sequence of interconnected gears


       pinion  [-display  host:display.screen]  [-window]  [-root]  [-install]  [-visual  visual]
       [-delay usecs] [-scroll ratio] [-spin ratio] [-size  ratio]  [-max-rpm  int]  [-wireframe]


       The pinion program draws an interconnected set of gears moving across the screen.


       pinion accepts the following options:

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

       -root   Draw on the root window.

               Install a private colormap for the window.

       -visual visual
               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.

       -delay usecs
               The delay between frames of the animation, in microseconds: default 15000.

       -spin ratio
               How fast the gears should spin; default 1.0.  2.0 means twice as fast,  0.5  means
               half as fast.

       -scroll ratio
               How fast the gears should scroll past the screen; default 1.0.  2.0 means twice as
               fast, 0.5 means half as fast.

       -size ratio
               How big the gears should be, on average; default 1.0.  2.0 means twice  as  large,
               0.5 means half as large.

       -max-rpm integer
               If  any  gear exceeds the maximum RPM, the current gear train is broken there, and
               we start a new train.  Default: 900 RPM.  (At 30 FPS, that's about half a rotation
               per frame.)

               Render in wireframe instead of solid.

       -fps    Display the current frame rate, CPU load, and polygon count.


       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.
