+Works on links beginning with ``http://``, ``https://``, or ``www.`` and
+ending with ``.org``, ``.net`` or ``.com``. Links can have trailing punctuation
+(periods, commas, close-parens) and leading punctuation (opening parens) and
+``urlize`` will still do the right thing.
+
+Links generated by ``urlize`` have a ``rel="nofollow"`` attribute added
+to them.
For example::
{{ value|urlize }}
If ``value`` is ``"Check out www.djangoproject.com"``, the output will be
-``"Check out www.djangoproject.com"``.
+``"Check out www.djangoproject.com"``.
+
+The ``urlize`` filter also takes an optional parameter ``autoescape``. If
+``autoescape`` is ``True``, the link text and URLs will be escaped using
+Django's built-in :tfilter:`escape` filter. The default value for
+``autoescape`` is ``True``.
