DESCRIPTION
     The original puzzle has each face cut by a diamond, so  that  there  are  5
     pieces,  4 corner pieces and one diamond piece in the center.  This was de-
     signed by Uwe Meffert and called the  Pyraminx  Cube.   Douglas  Hofstadter
     later  coined  it	a  Skewb  and it stuck.  The puzzle has period 3 turning
     (i.e.  each  half	turns  with  120  degree  intervals).	The  Skewb   has
     2^5*3^8*6!/2^6  or  3,149,280 different combinations (with centers oriented
     2^5*3^8*6!/2 or 100,766,960 different combinations).

     More recently, Disney released Mickey's Challenge, its  a	spherical  skewb
     with   a	pretty	 good	internal   mechanism.	Mickey's  challenge  has
     2^5*3^8*6!/36 5,598,720 visually different combinations).	 It  also  comes
     with a pretty neat book.  Also released is the Creative Puzzle Ball or Mef-
     fert's Challenge which has 4 rings in different colors.

     Mach  Balls  of the Hungarian Gyula Mach are similar but they do not have a
     ratchet mechanism and do not turn as easily or smoothly.	One  must  match
     the 12 different symbols of 4 each at the 12 intersection points.

FEATURES
     Press  "mouse-left" button to move a piece.  Release "mouse-left" button on
     a piece on the same face.	(Clicks on diamonds are  ignored).   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 read (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.

     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 diamond piece.  This does add complexity so
     there are 2 sets of records.

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

     Press ">" or "." keys to speed up the movement of pieces (not implemented).

     Press "<" or "," keys to slow down  the  movement	of  pieces  (not  imple-
     mented).

     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 Skewb2d as:
       /     Counterclockwise

     7 8 9   Upper Left, Up, Upper Right
       ^
     4<5>6   Left, Clockwise, Right
       v
     1 2 3   Lower Left, Down, Lower Right

     If the mouse is on a diamond, the above keys will not move cube because the
     move  is  ambiguous.   Also if the mouse is on a triangle, not all the keys
     will function because the puzzle will only rotate on the cuts, i.e. a  tri-
     angle  with  a  Upper  Left - Lower Right cut will rotate only Upper Left &
     Lower Right, a triangle with a Upper Right - Lower  Left  cut  will  rotate
     only Upper Right & Lower Left.  Therefore, a triangle can only move tangen-
     tial  to the center of the face. No doubt this is confusing, but the physi-
     cal skewb is the same way. In fact, that is part of its appeal.

     Key pad for other than Skewb2d, 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.  Its also possible to rotate whole cube with	an  axis
     through  a face with alt key is pressed (Tab key when using Windows).  This
     is not recorded as a turn.

     The title is in the following format (non-motif non-opengl version):
	    xskewb{2|3}d<dimension>:  (<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 skewb window (resource
	     name "geometry").

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

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

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

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

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

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

     -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 let-
	     ter 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 "+-"
	     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  lower-
	     case 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.

     -frame color
	     This option specifies the color of the frame (resource name "frame-
	     Color").

     -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 for 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").

     -[no]orient
	     This  option  allows you to access the oriented 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 xskewb you have.

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

SAVE FORMAT
     Here is the format for the xskewb configuration, starting position, and the
     movement of its pieces.

     Skewb2d with default colors, not randomized:
       0       R     Red
     1 2 3   B W G   Blue, White, Green
       4       P     Pink
       5       Y     Yellow

	    orient: 0-1 <0 false, 1 true; if 1 then lines on pieces to	be  ori-
	    ented>
	    practice: 0-1 <0 false, 1 true>
	    moves: 0-MAXINT <total number of moves>

	    startingPosition:  <2  dimensional array of face and corner position
	    and center diamond position, each face has 4 corner pieces	and  one
	    center  piece,  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 #: <direction> <control> <face> <corner>
     Each turn is with respect to a corner on a face.
     The corners start at the upper right and work clockwise.
     Direction is represented as 0 upper right, 1 lower right, 2 lower	left,  3
     upper left, 5 clockwise, 7 counterclockwise, 8 up, 9 right, 10 down, and 11
     left.
     Control  is  represented  as  0  or 1, 1 if the whole cube is moved at once
     (here the corner does not matter), 0 if not.  The xskewb record keeper does
     not count a control move as a move, but here we do.
