NAME
       piecewise - lots of moving circles intersecting in interesting ways.

SYNOPSIS
       piecewise [-display host:display.screen] [-visual visual] [-window]
       [-root] [-delay number] [-count number] [-ncolors number] [-colorspeed
       number] [-minradius number] [-maxradius number] [-no-db] [-fps]

DESCRIPTION
       This draws a bunch of moving circles which switch from visibility to
       invisibility when they intersect.

OPTIONS
       -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.

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

       -root   Draw on the root window.

       -delay number
               Per-frame delay, in microseconds.  Default: 5000 (0.01
               seconds.).

       -count number
               Number of circles.  Default: 32.

       -ncolors number
               Number of colors, only one of which is used at a time.
               Default: 256.

       -colorspeed number
               How fast the color changes (0 - 100).  Default: 10.

       -minradius number
               Minimum circle radius (as a proportion of screen height).
               Default: 0.05.

       -maxradius number
               Maximum circle radius (as a proportion of screen height).
               Default: 0.2.

       -db | -no-db
               Whether to double buffer.

       -fps    Display the current frame rate and CPU load.

ENVIRONMENT
       DISPLAY to get the default host and display number.

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