DESCRIPTION

       Ideal's  The  Missing Link, a 4x4 puzzle, riding on the wave of Rubik's
       Cube craze.  There are many variations on  this  theme,  including  the
       "6x6"  puzzle  and Babylon Tower.  What makes the Missing Link a harder
       puzzle to solve is that the 2 center positions rotate together.


FEATURES

       Press "mouse-left" button to move a tile.  Release "mouse-left"  button
       in  the same row would move the tile towards the space (unless there is
       no space in that row).  Release on a different row will move the  tiles
       up or down.

       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.

       "S" or "s" keys to start the auto-solver.  Only works on mxn where m  =
       4 and n = 4.

       Press  "O"  or "o" keys to toggle the orient mode.  Slightly more chal-
       lenging on (default is off).

       Press "M" or "m" keys to toggle the middle mode.  All the middle  tiles
       rotate  together.  This is considerably more challenging on (default is
       on).

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

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

       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 Missing Link as:
         8     Up
         ^
       4< >6   Left, Right
         v
         2     Down

       Use the shift key and the up or down  arrow  keys  to  rotate  all  the
       tiles.

       Use  the  control key and the keypad or arrow keys to reduce or enlarge
       the complexity of the puzzle.

       The title is in the following format (non-motif version):
              xmlink: <row>x<column> {norm|ind<control of movement  of  middle
              tiles>}  @  (<Number  of  moves>/{<Record number of moves> <user
              name>|"NEVER noaccess"|"practice"}) - <Comment>
       Movement of middle tiles are either move together or independent.
       If there is no record of the current puzzle, it displays  "NEVER  noac-
       cess".


OPTIONS

       -geometry {+|-}X{+|-}Y
               This  option sets the initial position of the missing link win-
               dow (resource name "geometry").

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

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

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

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

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

       -tile color
               This option specifies the tile color of the tiles in the  miss-
               ing link window (resource name "tileColor").

       -face{0|1|2|3|4|5|6|7} <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.  The 0th face is the last face
               face on missing link because I wanted that one to remain  white
               by default when there are more or less faces.

       -{border|bd} color
               This  option  specifies  the  border  color of the tiles in the
               missing link window (resource name "orderColor").

       -[no]install
               This option specifies if the colormap should  be  installed  or
               not (resource name "install").

       -picture filename
               This  option  specifies the file for the picture (resource name
               "picture").

       -delay msecs
               This option specifies the number of milliseconds  it  takes  to
               move a tile or a group of tiles one space (1-50) (resource name
               "delay").

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

       -bumpSound filename
               This option specifies the file for the bump sound for the slid-
               ing of (resource name "bumpSound").

       -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").

       -tiles <int>
               This option allows you to change the number of links in  a  row
               (resource name "tiles").

       -faces <int>
               This  option allows you to change the number of faces in column
               (resource name "faces").

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

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

       -base int
               This option specifies  the  base  used  (default  is  base  10)
               (resource name "base").

       -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 xmlink 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.


SAVE FORMAT

       Here is the format for the xmlink configuration, starting position, and
       the movement of its pieces.

              tiles: 1-8 <number of tiles in a row>
              faces: 1-8 <number of tiles in a column>
              middle: 0-1 <0 false, 1 true; if 1  then  middle  moves  as  one
              unit>
              orient: 0-1 <0 false, 1 true; if 1 then chain linked in order>
              moves: 0-MAXINT <total number of moves>

              startingPosition:  <array of tile positions where 0 is the empty
              space>

       This is then followed by the moves, starting from 1.
              move #: <direction> <tile> <shift>
       Direction is represented as 0 up, 1 right, 2 down, and 3 left.
       Tile is the column of tile.
       Shift is represented as 0 or 1, 1 if the whole puzzle is moved at  once
       (here  Tile  does not matter), 0 if not.  The xmlink record keeper does
       not count a control move as a move, but here we do.
