/// /**
///  * 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.
