 // This is a client library that constructs a MojoLogger that can talk to a
 // Mojo logging service (see ../interfaces/log.mojo). It provides a |MojoLogger|
 // implementation which can be used as the default environment logger.
 //
 // Example application that uses this log client to talk to the log service:
 //
 //  class MyApp : public mojo::ApplicationImplBase {
 //   public:
 //    void OnInitialize() override {
 //      LogPtr log;
 //      mojo::ConnectToService(shell(), "mojo:log", &log);
 //      mojo::log::InitializeLogger(std::move(log),
 //                                  mojo::Environment::GetDefaultLogger());
 //      mojo::Environment::SetDefaultLogger(mojo::log::GetLogger());
 //    }
 //
 //    void OnQuit() override {
 //      mojo::log::DestroyLogger();
 //    }
 //  };
 //
 //  MojoResult MojoMain(MojoHandle app_request) {
 //    MyApp app;
-//    return mojo::RunApplication(&app);
+//    return mojo::RunMainApplication(&app);
 //  }
