Makefile

# Makefiles! Every lazy programmer's best friend. Because
# just typing "make" is so much easier than scrolling
# through bash commands to find the last compile that
# you did.
#
# Note that $(OUTPUT_OPTION) is defined to be "-o $@" in my 
# case. This is defined by the compiler.
#
# So the embarrassing truth is I don't really know how 
# this all works. It's just a house of cards that I 
# occassionally add another component on to. If it were
# to collapse at some point, I'd be hopelessly lost.
