# A helper script that operates sort of like Make, except it is
# a lot easier to read and write than a Makefile, and it works on
# any POSIX system.
#
# I chose to use a custom build script instead of using Make because
# it is much more portable and flexible. This script doesn't only
# handle building the code, it also handles formatting it, as well
# as generating patch files.
