#ifndef nsAppShellSingleton_h__
#define nsAppShellSingleton_h__

 * This file is designed to be included into the file that provides the
 * nsIModule implementation for a particular widget toolkit.
 * The following functions are defined:
 *   nsAppShellInit
 *   nsAppShellShutdown
 *   nsAppShellConstructor
 * The nsAppShellInit function is designed to be used as a module constructor.
 * If you already have a module constructor, then call nsAppShellInit from your
 * 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.
