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       originally made around 1879 (the 14-15 puzzle of Sam Loyd was made soon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 "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 "Z" or "z" keys to randomize the puzzle.

       "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.


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 "reverse").

       -{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  triangles  window
               (resource name "tileColor").

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

       -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 (resource
               name "bumpSound").

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

       -size <int>
               This  option  allows you to change the number of triangles in a

       -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

       The format is not standard.  The reason for this is that this is simple
       and I do not know what the standard is.

              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.
