+of watched resources.

+It demonstrates how to:
+ * combine the workqueue with a cache to a full controller
+ * synchronize the controller on startup
+
+The example is based on https://git.k8s.io/community/contributors/devel/controllers.md.

+go run *.go -kubeconfig=/my/config -logtostderr=true
+```
