* Module Intent
*
* All the necessary initialization code for WinHelp belongs here.
* This code should only be active (loaded in memory in real mode only
* during program initialization and termination. That means that no
* modules that will be needed at other times should be here.
* Similarly, this module should not have code that is needed only
* rarely; the size of this module impacts the disk-load time of every
* WinHelp initialization, even for new instances. Code used only when
* unhiding help should not be here.
