 // This class acts as the browser-side host to a utility child process.  A
 // utility process is a short-lived process that is created to run a specific
 // task.  This class lives solely on the IO thread.
 // If you need a single method call in the process, use StartFooBar(p).
 // If you need multiple batches of work to be done in the process, use
 // StartBatchMode(), then multiple calls to StartFooBar(p), then finish with
 // EndBatchMode().
-// If you need to call Mojo services, use Start() to start the child
-// process and GetServiceRegistry() to get the service registry to connect to
-// the child's Mojo services.
+// If you need to bind Mojo interfaces, use Start() to start the child
+// process and GetRemoteInterfaces() to get the shell::InterfaceProvider to
+// connect to the child's Mojo interfaces.
 //
 // Note: If your class keeps a ptr to an object of this type, grab a weak ptr to
 // avoid a use after free since this object is deleted synchronously but the
 // client notification is asynchronous.  See http://crbug.com/108871.
