/**
 *
 * Base class for reStructuredText directives.
 *
 * The following attributes may be set by subclasses.  They are
 * interpreted by the directive parser (which runs the directive
 * class):
 *
 * - `required_arguments`: The number of required arguments (default:
 * 0).
 *
 * - `optional_arguments`: The number of optional arguments (default:
 * 0).
 *
 * - `final_argument_whitespace`: A boolean, indicating if the final
 * argument may contain whitespace (default: False).
 *
 * - `option_spec`: A dictionary, mapping known option names to
 * conversion functions such as `int` or `float` (default: {}, no
 * options).  Several conversion functions are defined in the
 * directives/__init__.py module.
 *
 * Option conversion functions take a single parameter, the option
 * argument (a string or ``None``), validate it and/or convert it
 * to the appropriate form.  Conversion functions may raise
 * `ValueError` and `TypeError` exceptions.
 *
 * - `has_content`: A boolean; True if content is allowed.  Client
 * code must handle the case where content is required but not
 * supplied (an empty content list will be supplied).
 *
 * Arguments are normally single whitespace-separated words.  The
 * final argument may contain whitespace and/or newlines if
 * `final_argument_whitespace` is True.
 *
 * If the form of the arguments is more complex, specify only one
 * argument (either required or optional) and set
 * `final_argument_whitespace` to True; the client code must do any
 * context-sensitive parsing.
 *
 * When a directive implementation is being run, the directive class
 * is instantiated, and the `run()` method is executed.  During
 * instantiation, the following instance variables are set:
 *
 * - ``name`` is the directive type or name (string).
 *
 * - ``arguments`` is the list of positional arguments (strings).
 *
 * - ``options`` is a dictionary mapping option names (strings) to
 * values (type depends on option conversion functions; see
 * `option_spec` above).
 *
 * - ``content`` is a list of strings, the directive content line by line.
 *
 * - ``lineno`` is the absolute line number of the first line
 * of the directive.
 *
 * - ``content_offset`` is the line offset of the first line of the content from
 * the beginning of the current input.  Used when initiating a nested parse.
 *
 * - ``block_text`` is a string containing the entire directive.
 *
 * - ``state`` is the state which called the directive function.
 *
 * - ``state_machine`` is the state machine which controls the state which called
 * the directive function.
 *
 * Directive functions return a list of nodes which will be inserted
 * into the document tree at the point where the directive was
 * encountered.  This can be an empty list if there is nothing to
 * insert.
 *
 * For ordinary directives, the list must contain body elements or
 * structural elements.  Some directives are intended specifically
 * for substitution definitions, and must return a list of `Text`
 * nodes and/or inline elements (suitable for inline insertion, in
 * place of the substitution reference).  Such directives must verify
 * substitution definition context, typically using code like this::
 *
 * if not isinstance(state, states.SubstitutionDef):
 * error = state_machine.reporter.error(
 * 'Invalid context: the "%s" directive can only be used '
 * 'within a substitution definition.' % (name),
 * nodes.literal_block(block_text, block_text), line=lineno)
 * return [error]
 *
