        """Register a new object type.

        This method is a very convenient way to add a new :term:`object` type
        that can be cross-referenced.  It will do this:

        - Create a new directive (called *directivename*) for documenting an
          object.  It will automatically add index entries if *indextemplate*
          is nonempty; if given, it must contain exactly one instance of
          ``%s``.  See the example below for how the template will be
          interpreted.
        - Create a new role (called *rolename*) to cross-reference to these
          object descriptions.
        - If you provide *parse_node*, it must be a function that takes a
          string and a docutils node, and it must populate the node with
          children parsed from the string.  It must then return the name of the
          item to be used in cross-referencing and index entries.  See the
          :file:`conf.py` file in the source for this documentation for an
          example.
        - The *objname* (if not given, will default to *directivename*) names
          the type of object.  It is used when listing objects, e.g. in search
          results.

        For example, if you have this call in a custom Sphinx extension::

           app.add_object_type('directive', 'dir', 'pair: %s; directive')

        you can use this markup in your documents::

           .. rst:directive:: function

              Document a function.

           <...>

           See also the :rst:dir:`function` directive.

        For the directive, an index entry will be generated as if you had prepended ::

           .. index:: pair: function; directive

        The reference node will be of class ``literal`` (so it will be rendered
        in a proportional font, as appropriate for code) unless you give the
        *ref_nodeclass* argument, which must be a docutils node class.  Most
        useful are ``docutils.nodes.emphasis`` or ``docutils.nodes.strong`` --
        you can also use ``docutils.nodes.generated`` if you want no further
        text decoration.  If the text should be treated as literal (e.g. no
        smart quote replacement), but not have typewriter styling, use
        ``sphinx.addnodes.literal_emphasis`` or
        ``sphinx.addnodes.literal_strong``.

        For the role content, you have the same syntactical possibilities as
        for standard Sphinx roles (see :ref:`xref-syntax`).

        """Register a new object type.

        This method is a very convenient way to add a new :term:`object` type
        that can be cross-referenced.  It will do this:

        - Create a new directive (called *directivename*) for documenting an
          object.  It will automatically add index entries if *indextemplate*
          is nonempty; if given, it must contain exactly one instance of
          ``%s``.  See the example below for how the template will be
          interpreted.
        - Create a new role (called *rolename*) to cross-reference to these
          object descriptions.
        - If you provide *parse_node*, it must be a function that takes a
          string and a docutils node, and it must populate the node with
          children parsed from the string.  It must then return the name of the
          item to be used in cross-referencing and index entries.  See the
          :file:`conf.py` file in the source for this documentation for an
          example.
        - The *objname* (if not given, will default to *directivename*) names
          the type of object.  It is used when listing objects, e.g. in search
          results.

        For example, if you have this call in a custom Sphinx extension::

           app.add_object_type('directive', 'dir', 'pair: %s; directive')

        you can use this markup in your documents::

           .. rst:directive:: function

              Document a function.

           <...>

           See also the :rst:dir:`function` directive.

        For the directive, an index entry will be generated as if you had prepended ::

           .. index:: pair: function; directive

        The reference node will be of class ``literal`` (so it will be rendered
        in a proportional font, as appropriate for code) unless you give the
        *ref_nodeclass* argument, which must be a docutils node class.  Most
        useful are ``docutils.nodes.emphasis`` or ``docutils.nodes.strong`` --
        you can also use ``docutils.nodes.generated`` if you want no further
        text decoration.  If the text should be treated as literal (e.g. no
        smart quote replacement), but not have typewriter styling, use
        ``sphinx.addnodes.literal_emphasis`` or
        ``sphinx.addnodes.literal_strong``.

        For the role content, you have the same syntactical possibilities as
        for standard Sphinx roles (see :ref:`xref-syntax`).
