1.16 + * The following functions are defined:
1.17 + * nsAppShellInit
1.18 + * nsAppShellShutdown
1.19 + * nsAppShellConstructor
1.20 + *
1.21 + * The nsAppShellInit function is designed to be used as a module constructor.
1.22 + * If you already have a module constructor, then call nsAppShellInit from your
1.23 + * module constructor.
1.24 + *
1.25 + * The nsAppShellShutdown function is designed to be used as a module
1.26 + * destructor. If you already have a module destructor, then call
1.27 + * nsAppShellShutdown from your module destructor.
1.28 + *
1.29 + * The nsAppShellConstructor function is designed to be used as a factory
1.30 + * method for the nsAppShell class.
