  # In the case of Devise, this *only* happens in the production env
  # This coupled with Rails 4's insistence that routes are not drawn twice,
  # poses quite a serious problem.

  # This is mainly why this whole file exists in the first place.
  #
  # Thus we need to make sure that the routes aren't drawn twice.
