/**
|
|
* 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.
