       queens - n queens screensaver


       queens  [-display  host:display.screen]  [-window]  [-root]  [-install]
       [-visual visual] [-delay microseconds] [-wireframe] [-fps]


       The queens program solves the n-queens problem (where, in this program,
       N  is  between  5  and  10 queens) using a straightforward backtracking
       algorithm.  The problem is: how may  one  place  N  queens  on  an  NxN
       chessboard such that no queen can attack a sister?


       queens 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

               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.


       It's not unknown for this and other OpenGL hacks to fail under hardware
       accelaration (UtahGLX) and take the X server with them.  Texture images
       must be 16x16 or 32x32 or 64x64 etc.
