+jQuery templates use constructs like:
+ 
+    {{if condition}} print something{{/if}}
+ 
+This, of course, completely screws up Django templates,
+because Django thinks {{ and }} mean something.
+ 
+Wrap {% verbatim %} and {% endverbatim %} around those
+blocks of jQuery templates and this will try its best
+to output the contents with no changes.
