# Download and execute this script in one-line with no temporary files:

#     ruby -e "$(curl http://gist.github.com/raw/323731/install_homebrew.rb)"

# I deliberately didn't DRY /usr/local references into a variable as this
# script will not "just work" if you change the destination directory. However
# please feel free to fork it and make that possible.
