# WTF is this? http://optionparser.rubyforge.org/
# why are there like 20 differnt option parsers all called
# OptionParser!? and seemingly no attempt at
# disambiguation. its like an oldskool CPAN clusterfuck
# all over again. This is what you get when a buncha non
# english speakers design a programming language in
# english, and a buncha SanFran webdesigners, in all their
# VWbug-pastelcolored-sushiloving-DeathCabforCutie glory
# flocked like hipster lemmings because Ruby was
# “written by a Japanese guy”. This language is seriously
# pissing me off. Why are smart people using this?
