This program implements a game of Sokoban. In an attempt to make the game easier to
use, the instructions for playing have been embedded into the source code. However,
in keeping with the spirit of the IOCCC, they've been ROT-13ed so as to maintain the
level of obfuscation.
Included as an additional resource is the 'original' set of Sokoban levels to
tackle, if you succeed in completing them or get bored or frustrated with them, the
source suggests a location where you can get many additional levels.
Usage is also detailed in the source, or you can run the program with no arguments.

GCC 2.9* compiles the program without warnings, however GCC3.* will warn that
"Multi-line character constants are deprecated". This warning can be safely ignored.
