// MODULE: "RegUtil.h"
//
// PURPOSE: class CRegUtil
// Encapsulates access to system registry.
// This is intended as generic access to the registry, independent of any particular
// application.
//
// PROJECT: first developed as part of Belief Network Editing Tools ("Argon")
// Later modified to provide more extensive features as part of version 3.0 of the
// Online Troubleshooter (APGTS)
//
// AUTHOR: Lonnie Gerrald (LDG), Oleg Kalosha, Joe Mabel

// ORIGINAL DATE: 3/25/98
