+   Reference to a term in the glossary.  The glossary is created using the
+   ``glossary`` directive containing a definition list with terms and
+   definitions.  It does not have to be in the same file as the ``term``
+   markup, in fact, by default the Python docs have one global glossary
+   in the ``glossary.rst`` file.
