  # An abstract base class for defining converters that can be used to convert
  # {AbstractNode} objects in a parsed AsciiDoc document to a backend format
  # such as HTML or DocBook.
  #
  # Concrete subclasses must implement the {#convert} method and, optionally,
  # the {#convert_with_options} method.

  # An abstract base class for built-in {Converter} classes.

    # Public: Converts the specified {AbstractNode} using the specified
    # transform and optionally additional options (when not empty).
    #
    # CAUTION: Method that handles the specified transform *may not* accept the
    # second argument with additional options, in which case an {ArgumentError}
    # is raised if the given +opts+ Hash is not nil. The additional options are
    # used in template-based backends to access convert helper methods such as
    # outline.
    #
    # See {Converter#convert} for more details.

    # Returns the [String] result of conversion
