+/**
+ * The nsIServiceManager manager interface provides a means to obtain
+ * global services in an application. The service manager depends on the
+ * repository to find and instantiate factories to obtain services.
+ *
+ * Users of the service manager must first obtain a pointer to the global
+ * service manager by calling NS_GetServiceManager. After that,
+ * they can request specific services by calling GetService. When they are
+ * finished they can NS_RELEASE() the service as usual.
+ *
+ * A user of a service may keep references to particular services indefinitely
+ * and only must call Release when it shuts down.
