       gnubik -  an interactive, graphic Magic cube program.


       gnubik [window_system_options] [-hvs]  [-z n]  [-a m]


       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.


       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.


       The  following  options  may  be  specified  on  the  command  line  at

       -z n   Draws a cube of dimension n, where n is positive.   The  default
              value of n is 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 slow down the whole

       -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.


       The  code  for  gnubik  was written in ANSI compliant C, using the Mesa
       graphics library, and the Gtk+ library.  As such, it should be easy  to
       generate  a version for any system complying with these standards.  The
       program was developed on a GNU/Linux platform running XFree86.


       The rendering process is  slow  -  especially  over  a  network,  since
       display  lists aren't currently used.  The entire image is re-rendered,
       during each refresh, regardless of which components have changed  their
