+// Baseclass for interfaces which only needs a start and a stop. The intention
+// Is that you can define your feature with a method like:
+// scoped_ptr<base::LifetimeInterface> StartFoo(arguments);
+// The caller has no way to interface with the FOO that was created, except for
+// deleting the pointer, which will stop FOO.
