* The following functions are defined:
|
|
* nsAppShellInit
|
|
* nsAppShellShutdown
|
|
* nsAppShellConstructor
|
|
*
|
|
* The nsAppShellInit function is designed to be used as a module constructor.

* The nsAppShellShutdown function is designed to be used as a module
|
|
* destructor. If you already have a module destructor, then call
|
|
* nsAppShellShutdown from your module destructor.
|
|
*
|
|
* The nsAppShellConstructor function is designed to be used as a factory
|
|
* method for the nsAppShell class.
