//
// NS_TermEmbedding() is called in ExitInstance()

the default implementation uses XUL, not native windows. Embedding
apps can override the default implementation by implementing the
nsIPromptService interface and registering a factory for it with
the same CID and Contract ID as the default's.
Note that this example implements the service in a separate DLL,
replacing the default if the override DLL is present. This could
also have been done in the same module, without a separate DLL.
See the PowerPlant example for, well, an example.
