nit: move this comment to the .cc file please.

+// for use. Example:
+//
+// On Android, the UI thread is managed by Java, so we need to attach and
+// start a special type of message loop to allow Chromium code to run tasks.
+//
+//  scoped_ptr<base::MessageLoopForUI> ui_loop;
+//  ui_loop_.reset(new base::MessageLoopForUI());
+//  ui_loop_->Start();
+//  scoped_ptr<ChromotingClientRuntime> runtime =
+//    ChromotingClientRuntime::Create(ui_loop.get());
+//
+// On iOS we created a new message loop and now attach it.
+//
+//  scoped_ptr<base::MessageLoopForUI> ui_loop;
+//  ui_loop_.reset(new base::MessageLoopForUI());
+//  base::MessageLoopForUI::current()->Attach();
+//  scoped_ptr<ChromotingClientRuntime> runtime =
