BUILDING
--------
To build just run 'make'.
DESCRIPTION
-----------
dbox is a simple brute-force Sokoban level solver. Usage is:
dbox [-v|-i|-p|-P] file [file2 ...]
-v - Be verbose. Print depth of search tree as searching is done.
-i - Interactive. Show an interactive version of the map once solved.
-P\-p - Play. Allows you to play the level.
The file is a Sokoban level defined like this:
Level 1
###
#.#
# ####
###B B.#
#. B@###
####B#
#.#
###
The first line is the title of the level.
The subsequent lines must all be of the same width and define the level. The
'#' character defines a wall. The 'B' character defines a box. The '.'
character defines a target square. The 'X' character can be used to define a
box already on a target square.
If no interactive mode is used the level will be displayed along with the
route to solve it, e.g.
Solving Level 1
###
#.#
# ####
###B B.#
#. B@###
####B#
#.#
###
Route = 'DULLRUUDRR'
INTERACTIVE MODE KEYS
---------------------
In interactive mode the following keys can be used.
P - Follow the solution path if one was found.
Backspace/B - Step back one move on the solution path.
Cursor Keys - Move. Note that the move will be blocked if the state of the
map is already known or moving a block will make the level
insoluble.
Q - Quit.
Cursors to move, P to follow path, Q to quit, Backspace/B to step back
