    Microsoft Confidential
    Copyright (c) Microsoft Corporation 1999
    All rights reserved

    Contains common macros, defined values, and other stuff I use all the
    time.

    1/98 - Jason Cohen (JCOHEN)
        Originally created as a helper header file for all my projects.

    4/99 - Jason Cohen (JCOHEN)
        Added this new header file for the OPK Wizard as part of the
        Millennium rewrite.
        
    09/2000 - Stephen Lodwick (STELO)
        Ported OPK Wizard to Whistler
