      # This cop checks whether the end keywords of method definitions are
      # aligned properly.
      #
      # Two modes are supported through the AlignWith configuration
      # parameter. If it's set to `start_of_line` (which is the default), the
      # `end` shall be aligned with the start of the line where the `def`
      # keyword is. If it's set to `def`, the `end` shall be aligned with the
      # `def` keyword.
      #
      # @example
      #
      #   private def foo
      #   end
