# Magic hooks that is necessary due to Bundler/RVM craziness interfering with
# our own Cucumbers. This is necessary because our Cucumber scenarios need to create a
# Ruby app that has a distinct, separate bundle from right_develop's own Gemfile, e.g. we
# need to test what happens when RSpec or Cucumber isn't available. Therefore the subprocesses
# that RightDevelop's Cucumber suite launches, should not inherit our bundle.
