NAME
       maze - an automated X11 demo repeatedly creating and solving a random maze

SYNOPSIS
       maze  [-display	host:display.screen]  [-foreground  color]  [-background color] [-window]
       [-root] [-install] [-visual visual] [-grid-size pixels] [-live-color  color]  [-dead-color
       color]  [-solve-delay  usecs]  [-pre-delay usecs] [-post-delay usecs] [-generator integer]
       [-max-length integer] [-bridge] [-no-bridge]

DESCRIPTION
       The maze program creates a "random" maze and then solves it with graphical feedback.

OPTIONS
       maze accepts the following options:

       -window Draw on a newly-created window.	This is the default.

       -root   Draw on the root window.

       -install
	       Install a private colormap for the window.

       -visual visual
	       Specify which visual to use.  Legal values are the name of a visual class, or  the
	       id number (decimal or hex) of a specific visual.

       -grid-size pixels
	       The size of each block of the maze, in pixels; default is 0, meaning pick a random
	       grid size.

       -live-color color
	       The color of the path.

       -dead-color color
	       The color of the failed path (it is also stippled with a 50% pattern.)

       -skip-color color
	       The maze solver will choose to not go down a path if it can "see" (in  a  straight
	       line)  that it is a dead end.  This is the color to use for paths that are skipped
	       for this reason.

       -surround-color color
	       If the maze solver ever completely encloses an area within the maze, then it knows
	       that  the  exit	is  not in there (and in fact the interior of that area might not
	       even be reachable.)  It will mark out those cells using this color.

       -solve-delay integer
	       Delay (in microseconds) between each step of the solution path.	Default 5000,  or
	       about 1/200th second.

       -pre-delay integer
	       Delay  (in  microseconds)  between  generating  a  maze	and starting to solve it.
	       Default 2000000 (2 seconds.)

       -post-delay integer
	       Delay (in microseconds) after solving a maze and  before  generating  a	new  one.
	       Default 4000000 (4 seconds.)

       -generator num
	       Sets  the  algorithm  that  will be used to generate the mazes. The default is -1,
	       which randomly selects an algorithm for each maze that is generated.  Generator	0
	       is  the	original  one,	and works by walking around randomly until we hit a place
	       we've been before, then backtracking and trying a new direction somewhere. Genera-
	       tor  1  picks a random spot in the maze, then draws a straight wall from that spot
	       in a random direction until it hits another wall (and continues until the maze  is
	       complete).  Generator  2  is  based  on sets. Initially all cells are in different
	       sets. Then two neighboring cells are chosen and if they	are  in  different  sets,
	       their sets are joined. If they were in the same set, a wall is built between them.
	       This continues until the maze is complete.

	       All generators generate mazes with a certain 'characteristic'. See if you can spot
	       them!

       -max-length num
	       Controls the maximum length of walls drawn in one go by generator 1.

       -bridge

       -no-bridge
	       Controls whether or not a 'bridge' will appear over the logo.

       Clicking the mouse in the maze window controls it.

       LeftButton      Clears the window and restarts maze.

       MiddleButton    Pause or unpause the program.

       RightButton     Exit.

BUGS
       Expose events force a restart of maze.

       Mouse  actions  are  based on "raw" values (Button1, Button2 and Button3) instead of using
       the pointer map.

ENVIRONMENT
       DISPLAY to get the default host and display number.

       XENVIRONMENT
	       to get the name of a resource file that overrides the global resources  stored  in
	       the RESOURCE_MANAGER property.
