/**
 * 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.
