.SH 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originally made around 1879 (the 14\-15 puzzle of Sam Loyd was made soon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.
.SH FEATURES
Click "\fBmouse\-left\fP" 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.
.LP
Click "\fBmouse\-right\fP" button, or press "\fBC\fP" or "\fBc\fP" keys, to
clear the puzzle.
.LP
"\fBS\fP" or "\fBs\fP" keys reserved for the auto\-solver (not implemented).
.LP
Press "\fBG\fP" or "\fBg\fP" keys to get a saved puzzle.
.LP
Press "\fBW\fP" or "\fBw\fP" keys to save (write) a puzzle.
.LP
Press "\fBU\fP" or "\fBu\fP" keys to undo a move.
.LP
Press "\fBR\fP" or "\fBr\fP" keys to redo a move.
.LP
Press "\fBZ\fP" or "\fBz\fP" keys to randomize the puzzle.  New records
can only be set from a cleared state.
.LP
"\fBS\fP" or "\fBs\fP" keys reserved for the auto\-solver (not implemented).
.LP
Press "\fBI\fP" or "\fBi\fP" keys to increase the number of tiles.
.LP
Press "\fBD\fP" or "\fBd\fP" keys to decrease the number of tiles.
.LP
Press "\fB>\fP" or "\fB.\fP" keys to speed up the movement of tiles.
.LP
Press "\fB<\fP" or "\fB,\fP" keys to slow down the movement of tiles.
.LP
Press "\fB@\fP" key to toggle the sound.
.LP
Press "\fBEsc\fP" key to hide program.
.LP
Press "\fBQ\fP", "\fBq\fP", or "\fBCTRL\-C\fP" keys to kill program.
.LP
Use the key pad or arrow keys to move without the mouse.
.br
Key pad is defined for Triangles as:
.br
7   9   Upper Left, Upper Right
.br
  ^
.br
4< >6   Left, Right
.br
  v
.br
1   3   Lower Left, Lower Right

The title is in the following format (non\-motif version):
.RS
xtriangles: <size> @ (<Number of moves>/{<Record number of moves>
<user name>|"NEVER noaccess"}) \- <Comment>
.RE
If there is no record of the current puzzle, it displays "NEVER noaccess".
.SH OPTIONS
.TP 8
.B \-geometry {+|\-}\fIX\fP{+|\-}\fIY\fP
This option sets the initial position of the triangles window (resource
name "\fIgeometry\fP").
.TP 8
.B \-display \fIhost\fP:\fIdpy\fP
This option specifies the X server to contact.
.TP 8
.B \-[no]mono
This option allows you to display the triangles window on a color screen
as if it were monochrome (resource name "\fImono\fP").
.TP 8
.B \-[no]{reverse|rv}
This option allows you to see the triangles window in reverse video
(resource name "\fIreverseVideo\fP").
.TP 8
.B \-{foreground|fg} \fIcolor\fP
This option specifies the foreground of the triangles window (resource name
"\fIforeground\fP").
.TP 8
.B \-{background|bg} \fIcolor\fP
This option specifies the background of the triangles window (resource name
"\fIbackground\fP").
.TP 8
.B \-tile \fIcolor\fP
This option specifies the tile color of the tiles in the triangles window
(resource name "\fItileColor\fP").
.TP 8
.B \-text \fIcolor\fP
This option specifies the text color of the tiles in the triangles window
(resource name "\fItextColor\fP").
.TP 8
.B \-delay \fImsecs\fP
This option specifies the number of milliseconds it takes to move a tile or
a group of tiles one space (1\-50) (resource name "\fIdelay\fP").
.TP 8
.B \-[no]sound
This option specifies if a sliding tile should make a sound or not
(resource name "\fIsound\fP").
.TP 8
.B \-bumpSound \fIfilename\fP
This option specifies the file for the bump sound for the sliding
the tiles (resource name "\fIbumpSound\fP").
.TP 8
.B \-{font|fn} \ffontname\fP
This option specifies the font that will be used (resource name
"\fIfont\fP").
.TP 8
.B \-size <\fIint\fP>
This option allows you to change the number of triangles in a row (resource
name "\fIsizeA\fP").
.TP 8
.B \-base \fIint\fP
This option specifies the base used (default is base 10) (resource name
"\fIbase\fP").
.TP 8
.B \-userName \fIstring\fP
This option specifies the user name for any records made or else it will
get your login name (resource name "\fIuserName\fP").
.TP 8
.B \-scoreFile \fIfilename\fP
Specify an alternative score file (resource name "\fIscoreFile\fP").
.TP 8
.B \-scores
This option lists all the recorded scores and then exits.
.TP 8
.B \-version
This option tells you what version of xtriangles you have.
.SH 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.
.SH SAVE FORMAT
Here is the format for the xtriangles configuration, starting position, and
the movement of its pieces.
.sp
.RS
size: 1\-16 <number of tiles in a row of the same orientation as the puzzle>
.br
moves: 0\-MAXINT <total number of moves>
.sp
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>
.RE
.sp
This is then followed by the moves, starting from 1.
.RS
move #: <direction>
.RE
Direction is represented as 0 upper right, 1 right, 2 lower right,
3 lower left, 4 left, and 5 upper left.
