+// Note that, to run ARC practically, it is necessary to meet more conditions, |
+// e.g., ARC supports only on Primary User Profile. To see if ARC can actually |
+// run for the profile etc., arc::ArcSessionManager::IsAllowedForProfile() is |
+// the function for that purpose. Please see also its comment, too. |
+// Also note that, ARC singleton classes (e.g. ArcSessionManager, |
+// ArcServiceManager, ArcServiceLauncher) are instantiated regardless of this |
+// check, so it is ok to access them directly. |
