+Running Deliverance Themeswitcher
+--------------------------------------
+
+The files prefixed with ``dv`` connote the adaption of this to
+actually do Deliverance themeswitching middleware:
+
+1) ``sh dvrun.sh``
+
+2) Go to ``http://localhost:8080/example.html``
+
+You might have to reload that URL a second time to get it to take
+affect.  Note that this example doesn't switch rule files, but that's
+easy (just call ``set_rule_uri``).
