/*++ BUILD Version: 0001     Increment this if a change has global effects

Copyright (c) 1993-1999  Microsoft Corporation

Module Name:

    imagehlp.x

Abstract:

    Used with hextract.exe, build imagehlp.h and dbghelp.h.

    As imagehlp.h, this module defines the prototypes and constants
    required for the image help routines.

    As dbghelp.h, it also contains debugging support routines that
    are redistributable.
