  # We are going to shell out rather than invoking Bundler::CLI.new(command)
  # because `rails new` loads the Thor gem and on the other hand bundler uses
  # its own vendored Thor, which could be a different version. Running both
  # things in the same process is a recipe for a night with paracetamol.
  #
  # We use backticks and #print here instead of vanilla #system because it
  # is easier to silence stdout in the existing test suite this way. The
  # end-user gets the bundler commands called anyway, so no big deal.
  #
  # Thanks to James Tucker for the Gem tricks involved in this call.
