# File: Battleship.pm
#
# Purpose: Simplified version of the Battleship board game.
#
# Note: This code was written circa 1993 for a DikuMUD fork. It was originally
# written in C, as I was teaching the language to myself in my early teens. Two
# decades or so later, I transliterated this code from C to Perl for PBot. Much
# of the "ugly" C-style design of this code has been preserved for personal
# historical reasons -- I was inspired by the IOCCC and I attempted to be clever
# with nested conditional operators and other silliness. Please be gentle if you
# read this code. :)
