/**************************************************************************
*
* Name : main(argc, argv)
*
* Description: Initializes the application, gets and dispatches messages
* for the client window on thread 1 and terminates the
* application when a WM_QUIT message is received. It then
* saves the configuration in os2.ini, destroys all OS/2
* PM resources, and terminates.
*
* The following routine is the Presentation Manager program
* main body. The main body of a PM program is concerned with
* associating the application with the Presentation Manager
* system, creating its message queue, registering and displaying
* its main window, servicing its message queue during the time
* that the application is active, and disassociating the
* application from PM when the user is finished with the
* it. The remaining parts of this source module that are
* concerned with the Presentation Manager are the application's
* window procedures (main window procedure, child window
* procedures, and dialog window procedures) that process the
* messages associated with the application's various windows.
*
* Concepts : - obtains anchor block handle and creates message
* queue
* - creates the main frame window which creates the
* main client window
* - polls the message queue via Get/Dispatch Msg loop
* - upon exiting the loop, exits
*
* API's : WinInitialize
* WinCreateMsgQueue
* WinRegisterClass
* WinLoadString
* WinCreateHelpInstance
* WinMessageBox
* WinCreateStdWindow
* WinQueryWindowULong
* WinAssociateHelpInstance
* WinAddSwitchEntry
* WinGetMsg
* WinDispatchMsg
* WinRemoveSwitchEntry
* WinDestroyHelpInstance
* WinDestroyWindow
* WinDestroyMsgQueue
* WinTerminate
*
* Parameters : [none]
*
* Return : Always returns zero. The ANSI standard requires that
* main be declared as an INT.

SAVER_PROC

* call the configuration dialog of the saver module
* copy the name of the saver module into the supplied buffer
* tell if the saver module is enabled
* set the "enabled" state of the saver module
* start the saver
* stop the saver
Note that before any processing is done, module configuration data is
