+=head1 USAGE
+
+Needs access to
+http://localhost:8080/gwc (or modify the address for another host).
+
+If geowebcache is used inside GeoServer the url will be
+http://localhost:8080/geoserver/gwc
+
+GeoWebCache 1.2 or higher.
+
+Tip: To see if it's already set up correctly, just run this plugin
+with the parameter "autoconf". If you get a "yes", everything should
+work like a charm already.
