      # might want us to use a bundled version instead of a
      # gem/apt-get/yum/whatever-installed version. Therefore we must setup
      # the correct load paths before requiring 'rack'.
      #
      # The most popular tool for bundling dependencies is Bundler. Bundler
      # works as follows:
      # - If the bundle is locked then a file .bundle/environment.rb exists
      #   which will setup the load paths.
      # - If the bundle is not locked then the load paths must be set up by
      #   calling Bundler.setup.
      # - Rails 3's boot.rb automatically loads .bundle/environment.rb or
      #   calls Bundler.setup if that's not available.
      # - Other Rack apps might not have a boot.rb but we still want to setup
      #   Bundler.
      # - Some Rails 2 apps might have explicitly added Bundler support.
      #   These apps call Bundler.setup in their preinitializer.rb.
      #
      # So the strategy is as follows:

# Our strategy might be completely unsuitable for the app or the
      # developer is using something other than Bundler, so we let the user
      # manually specify a load path setup file.
      if options["load_path_setup_file"]

      # environment lock file. This has been replaced by Gemfile.lock/gems.locked
      # in later versions, but we still support the older mechanism.
      # If the Bundler environment lock file exists then load that. If it

      # possibilities:
      # 1. Bundler is not used, in which case we don't have to do anything.
      # 2. Bundler *is* used, but either the user is using a newer Bundler versions,
      #    or the gems are not locked. In either case, we're supposed to call
      #    Bundler.setup.
      #
      # The existence of Gemfile/gems.rb indicates whether (2) is true:
      elsif File.exist?('Gemfile') || File.exist?('gems.rb')

        # However older versions of Rails may not so loading boot.rb might
        # not be the correct thing to do. To be on the safe side we
        # call Bundler.setup ourselves; calling Bundler.setup twice is
        # harmless. If this isn't the correct thing to do after all then
        # there's always the load_path_setup_file option and
