Meme generator using local images

meme.rb

#!/usr/bin/env ruby
#
# OMG THIS CODE IS SO UGLY
# but...
# IT WORKS!!
#
# Hacked together by http://github.com/marcinbunsch
#
# This assumes the following:
# - That you're on a Mac
# - That you have ImageMagick installed
# - That you have the impact font in /Library/Fonts/Impact.ttf
# - That you have a ~/Drawer folder with source jpeg files
# - That you have a Dropbox account
#
# Example:
#  If I have a yuno.jpg file in ~/Drawer and run:
#    meme "Y U NO" "HAVE YOUR OWN MEME GENERATOR" --source yuno --name yuno.generator --dropbox
#  It will create a file yuno.generator.jpg based on yuno.jpg in ~/Dropbox/Public/memes and copy the link to clipboard
#
