## DESCRIPTION

           A sliding tile puzzle.  A triangular version of the 15 puzzle which was
           originally made around 1879 (the 14-15 puzzle of Sam Loyd was made soon
           after).    T. R. Dawson in Original Puzzles has a similar puzzle with 4
           diamond- and 6 triangular-shaped pieces.   This  puzzle  is  easier  to
           solve than 15 puzzle.

## FEATURES

           Click  "mouse-left" button to move a tile.  Clicks on spaces, or clicks
           on tiles that are not in line with two spaces,  will  not  move  tiles.
           Notice,  one  can  move more than one tile at a time by clicking on the
           tile farthest from the spaces but still in line with the spaces.

           Click "mouse-right" button, or press "C" or "c" keys, to clear the puz-
           zle.

           "S" or "s" keys reserved for the auto-solver (not implemented).

           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 "Z" or "z" keys to randomize the puzzle.  New records can only be
           set from a cleared state.

           "S" or "s" keys reserved for the auto-solver (not implemented).

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

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

           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 Triangles as:
           7   9   Upper Left, Upper Right
             ^
           4< >6   Left, Right
             v
           1   3   Lower Left, Lower Right

           The title is in the following format (non-motif version):
                  xtriangles: <size>  @  (<Number  of  moves>/{<Record  number  of
                  moves> <user name>|"NEVER noaccess"}) - <Comment>
           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  triangles  window
                   (resource name "geometry").

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

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

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

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

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

           -tile color
                   This option specifies the tile color of the tiles in the trian-
                   gles window (resource name "tileColor").

           -text color
                   This option specifies the text color of the tiles in the trian-
                   gles window (resource name "textColor").

           -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 the tiles (resource name "bumpSound").

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

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

           -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 xtriangles 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 xtriangles configuration, starting position,
           and the movement of its pieces.

                  size:  1-16 <number of tiles in a row of the same orientation as
                  the puzzle>
                  moves: 0-MAXINT <total number of moves>

                  startingPosition: <array of tile positions where 0 is the  empty
                  space for the UP triangle and -1 is the empty space for the DOWN
                  triangle>

           This is then followed by the moves, starting from 1.
                  move #: <direction>
           Direction is represented as 0 upper right, 1 right, 2  lower  right,  3
           lower left, 4 left, and 5 upper left.
