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 "R" or "r" keys to read a saved puzzle.

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

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

       Press "E" or "e" 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 other than Rubik2d, 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 non-opengl 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.
