NAME
       gnubik -  an interactive, graphic Magic cube program.

SYNOPSIS
       gnubik [window_system_options] [-hvs]  [-z n[,m[,p]]]  [-a m]


DESCRIPTION
       This  is  a program which displays a 3 dimensional image of a
       magic cube, as introduced  to  the  world  by  its  Hungarian
       inventor,  Erno  Rubik.   The  user rotates the blocks of the
       cube, and attempts to solve the puzzle,  by  moving  all  the
       blocks to their correct positions and orientations, resulting
       in a cube with a single colour on each face.

OPERATION
       The user interacts with the program in the following ways:

   Viewing the Cube
       The viewing position may be altered using the arrow  keys  or
       by using the mouse.  The left and right arrow keys rotate the
       cube about the vertical axis.  The up and  down  keys  rotate
       the  cube  about the horizontal axis.  Holding down the shift
       key whilst pressing the left and right arrow keys rotates the
       cube about the z axis.

       To  rotate  the  cube using the mouse, hold down button 1 and
       move the mouse anywhere on the window.  If your mouse  has  a
       scroll wheel, you can use this to rotate the cube about the z
       axis.


   Performing Rotations
       Rotations are performed using the mouse.  To  manipulate  the
       cube, place the mouse cursor on a square in the cube, against
       the edge facing the direction you want  to  move,  and  click
       button 1.

       The mouse cursor will indicate the direction of rotation.


OPTIONS
       The following options may be specified on the command line at
       invocation.

       -z n,m,p
              Draws a cube of size n x m x p, where n,m  and  p  are
              positive.  The default size is 3 x 3 x 3.

       -a m   When  rotating  parts of the cube, show m intermediate
              positions.  The default for this value is 2.   Setting
              to  a higher value, will give smoother animations, but
              will result in a slower program.

       -s     Starts with the cube already solved.  By  default,  it
              starts in a random position.

       -h     Display a help message and exit.

       -v     Display version number and then exit.


IMPLEMENTATION
       The  code  for gnubik is written in C and Scheme. It uses the
       Mesa/OpenGL graphics library, and the Gtk+ library and Guile.
       As such, it should be easy to generate a version for any sys‐
       tem complying with these standards.

BUGS
       The rendering process is slower than it could be, since  dis‐
       play  lists  aren't  currently used.  The entire image is re-
       rendered, during each refresh, regardless of which components
       have changed their appearance.
