Opinionated version of the bootstrap file

bootstrap-rvm.sh

# Based on: https://gist.github.com/TylerRick/1961638

# vim: set ft=sh
#
# This script automatically bootstraps the system with everything it needs to run chef-solo.
# Note: This should only do the absolute minimum necessary to get chef-solo (and your recipes)
# working. All else should be done via chef recipes.
