+Testing for multipart forms
+~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+If you're writing some reusable views or templates, you may not know ahead of
+time whether your form is a multipart form or not. The ``is_multipart()``
+method tells you if the form requires multipart encoding for submission::
+
+    >>> f = ContactFormWithMugshot()
+    >>> f.is_multipart()
+    True
+
+In a template, this sort of code could be useful::
+
+    {% if form.is_multipart %}
+      <form enctype="multipart/form-data" method="post" action="/foo/">
+    {% else %}
+      <form method="post" action="/foo/">
+    {% endif %}
+    {% form %}
+    </form>
