 * ``HORIZONTALLINE`` is used sparingly as a separator in long descriptions.  It becomes a horizontal rule (the ``<hr>`` html tag) in the documentation.

   For links between modules and documentation within a collection, you can use any of the options above. For links outside of your collection, use ``R()`` if available. Otherwise, use ``U()`` or ``L()`` with full URLs (not relative links). For modules, use ``M()`` with the FQCN or ``ansible.builtin`` as shown in the example. If you are creating your own documentation site, you will need to use the `intersphinx extension <https://www.sphinx-doc.org/en/master/usage/extensions/intersphinx.html>`_ to convert ``R()`` and ``M()`` to the correct links.
