DESCRIPTION

       The original puzzle has 9 squares per face (size = 3).  The puzzle  was
       designed  by  Erno  Rubik  and  called  the  Rubik’s  Cube.   This  has
       8!*12!*3^8*2^12/12 or 4.3 * 10^19 different combinations.

       The Pocket Cube has 4 squares per face (size = 2) also designed by Erno
       Rubik.  This has 7!*3^6 or 3,674,160 different combinations.

       Rubik’s  Revenge  has  16  squares per face (size = 4) also designed by
       Erno Rubik.  This has 7!*3^6*24!*24!/(4!)^6 or 7.4  *  10^46  different
       combinations.

       5x5x5  Cube.   This has 8!*12!*3^7*2^10*(24!)^3/(4!)^12 or 2.83 * 10^74
       different combinations.

       There is also the  Magic  Domino  3x3x2  cube  which  has  (8!)^2/4  or
       406,425,600 combinations.

       A  physical  6x6x6 cube is possible but to my knowledge no one has been
       too successful in building one.  7x7x7 is also possible, but  here  one
       must  make the center most cubes smaller than the outside cubes, so the
       corners do not fall off when turned.

FEATURES

       Press "mouse-left" button to move a piece.  Release "mouse-left" button
       on  a piece on the same face and in the same row.  The pieces will then
       turn towards where the mouse button was released.

       Click "mouse-center", or press "P" or "p" keys to toggle  the  practice
       mode (in practice mode the record should say "practice").  This is good
       for learning moves and experimenting.

       Click "mouse-right", or press "Z" or "z" keys, to randomize the  puzzle
       (this must be done first to set a new record).

       Press "G" or "g" keys to get a saved puzzle.

       Press "W" or "w" keys to save (write) a puzzle.

       Press "U" or "u" keys to undo a move.

       Press "R" or "r" keys to redo a move.

       Press "C" or "c" keys to clear the puzzle.

       Press  "S"  or  "s"  keys  to  start auto-solver.  Only works on 1x1x1,
       2x2x2, and 3x3x3 cubes.

       Press "O" or "o" keys to toggle the orient mode.  One has to orient the
       faces  in  orient  mode,  besides  getting all the faces to be the same
       color.  To do this one has to get the lines to be oriented in the  same
       direction,  this only matters with center piece, if at all (i.e.  those
       pieces not on a corner or edge).  This does add complexity so there are
       2 sets of records.

       Press "I" or "i" keys to increase the number of pieces.

       Press "D" or "d" keys to decrease the number of pieces.

       Press "x" key to increase the number of pieces along the x axis.

       Press "X" key to decrease the number of pieces along the x axis.

       Press "y" key to increase the number of pieces along the y axis.

       Press "Y" key to decrease the number of pieces along the y axis.

       Press "f" key to increase the number of pieces along the z axis.

       Press "F" key to decrease the number of pieces along the z axis.

       Press "V" or "v" keys to change the view of the cube.

       Press ">" or "." keys to speed up the movement of pieces.

       Press "<" or "," keys to slow down the movement of pieces.

       Press "@" key to toggle the sound.

       Press "Esc" key to hide program.

       Press "Q", "q", or "CTRL-C" keys to kill program.

       Use the key pad or arrow keys to move without the mouse.
       Key pad is defined for the Rubik2d as:
         /     Counterclockwise

         8     Up
         ^
       4<5>6   Left, Clockwise, Right
         v
         2     Down

       Key  pad for Rubik3d, use must use your intuition (is this a cop out or
       what?).  The key pad is defined differently depending on which side  of
       the  cube  your mouse is pointing at.  One thing that stays the same is
       "5" is Clockwise and "/" is Counterclockwise.

       Use the control key and the left mouse button, keypad, or arrow keys to
       move the whole cube.  This is not recorded as a turn.

       The title is in the following format (non-motif version):
              xrubik{2|3}d<dimension>:   {1|2|3|4|5|6<cubes  per  edge  on  x-
              axis>x{1|2|3|4|5|6<cubes per edge on  y-axis>x{1|2|3|4|5|6<cubes
              per  edge  on  z-axis>}  @ (<Number of moves>/{<Record number of
              moves> <user name>|"NEVER noaccess"|"practice"}) - <Comment>
       If there is no  record  of  the  current  puzzle,  it  displays  "NEVER
       noaccess".

OPTIONS

       -geometry {+|-}X{+|-}Y
               This  option  sets  the  initial  position  of the rubik window
               (resource name "geometry").

       -display host:dpy
               This option specifies the X server to contact.

       -[no]mono
               This option allows you to display the rubik window on  a  color
               screen as if it were monochrome (resource name "mono").

       -[no]{reverse|rv}
               This option allows you to see the rubik window in reverse video
               (resource name "reverseVideo").

       -{foreground|fg} color
               This option  specifies  the  foreground  of  the  rubik  window
               (resource name "foreground").

       -{background|bg} color
               This  option  specifies  the  background  of  the  rubik window
               (resource name "background").

       -face{0|1|2|3|4|5} <color>
               This option allows you to change the color of a face  (resource
               name  "faceColorN").  In mono-mode, color is represented as the
               first letter of the color name. On the 2-D version,  the  faces
               are  ordered  top  to  bottom  and  left  to  right  on the "t"
               configuration.  The  sideways  "t"  or  "+-"  configuration  is
               physically  consistent with the former, so it is ordered "0, 1,
               2, 3, 5, 4".  If you has two colors that begin  with  the  same
               letter you should have one in uppercase and one in lowercase to
               distinguish them in mono-mode. You can change the colors of the
               faces  to  make  a stupid cube (i.e.  all White or in mono-mode
               all "W"). Unfortunately, it will not normally  say  its  solved
               when its randomized. This would be cheating.

       -{border|bd} color
               This  option  specifies  the  border color of the pieces in the
               rubik window (resource name "borderColor").

       -delay msecs
               This option specifies the number of milliseconds  it  takes  to
               move pieces (1-50) (resource name "delay").

       -[no]sound
               This  option specifies if sliding pieces should make a sound or
               not (resource name "sound").

       -moveSound filename
               This option specifies the file for the move sound the  twisting
               of the puzzle (resource name "moveSound").

       -{font|fn} ontname
               This option specifies the font that will be used (resource name
               "font").

       -view <int>
               This option allows you to change  the  view  of  the  cube  for
               OpenGL with choice of 4 views (resource name "int").

       -sizex <int>
               This option allows you to change the number of pieces on a edge
               along x-axis (resource name "sizex").

       -sizey <int>
               This option allows you to change the number of pieces on a edge
               along y-axis (resource name "sizey").

       -sizez <int>
               This option allows you to change the number of pieces on a edge
               along z-axis (resource name "sizez").

       -[no]orient
               This option allows you to access the orient mode (resource name
               "orient").

       -[no]practice
               This  option  allows  you to access the practice mode (resource
               name "practice").

       -userName string
               This option specifies the user name for  any  records  made  or
               else it will get your login name (resource name "userName").

       -scoreFile filename
               Specify  an alternative score file (resource name "scoreFile").

       -scores This option lists all the recorded scores and then exits.

       -version
               This option tells you what version of xrubik you have.

RECORDS

       You must randomize the puzzle before a  record  is  set,  otherwise  an
       assumption  of cheating is made if it is solved after a get or an auto-
       solve.

SAVE FORMAT

       Here is the format for the xrubik configuration, starting position, and
       the movement of its pieces.  The format is not standard.  The reason is
       that this is simple to produce and the standard notation is no good for
       variable number of pieces.

       Rubik2d with default colors, not randomized (front is face 2) :
         0       R     Red
       1 2 3   Y W G   Yellow, White, Green
         4       O     Orange
         5       B     Blue

              sizex: 1-6 <the number of cubes per row along x-axis>
              sizey: 1-6 <the number of cubes per row along y-axis>
              sizez: 1-6 <the number of cubes per row along z-axis>
              orient:  0-1  <0  false, 1 true; if 1 then lines on pieces to be
              oriented>
              practice: 0-1 <0 false, 1 true>
              moves: 0-MAXINT <total number of moves>

              startingPosition:  <2  dimensional  array  of  face  and   piece
              position,  each  face  has  size1 * size2 pieces, if orient mode
              then orientation number follows face number: 0 up,  1  right,  2
              down, and 3 left>

       This is then followed by the moves, starting from 1.
              move #: <face> <position> <direction> <control>
       Each turn is with respect to a face and position.
       Position is 0 to size * size - 1.  Position 0 is in the upper left.
       Direction is represented as 0 up, 1 right, 2 down, 3 left, 5 clockwise,
       and 7 counterclockwise.
       Control is represented as 0 or 1, 1 if the whole cube is moved at  once
       (here  position  does  not matter), 0 if not.  The xrubik record keeper
       does not count a control move as a move, but here we do.

       If you have a Rubik’s Cube you can not solve (2x2x2 or 3x3x3) enter  it
       in  rubik.log  file.   Have  size  =  2 or 3, orient = 0, practice = 0,
       randomized = 1, and moves = 0 and the  number  representation  for  the
       color  of  the  piece (usually 0=R, 1=Y, 2=W, 3=G, 4=O, 5=B).  Bring up
       xrubik, hit ’g’ so it will get your configuration and then ’s’ to solve
       your  cube  and  then  ’w’  to  write out the steps.  Then examine your
       rubik.log file.
