  # RDoc stops processing comments if it finds a comment line CONTAINING
  # '<tt>#--</tt>'. This can be used to separate external from internal
  # comments, or to stop a comment being associated with a method,
  # class, or module. Commenting CAN be turned back on with
  # a line that STARTS '<tt>#++</tt>'.

  #   TODO: require the leading #, to provide the feature in simple text files.
  #   Note: in ruby & C code, we require '#--' & '#++' or '*--' & '*++',
  #   to allow rules:
  #
  #   # this is a comment
  #   #---
  #   # private text
