Module Name:

    dbgspl.c

Abstract:

    This module provides all the Spooler Subsystem Debugger extensions.

Author:

    Krishna Ganugapati (KrishnaG) 1-July-1993

Revision History:

    KrishnaG:       Created: 1-July-1993 (imported most of IanJa's stuff)
    KrishnaG:       Added:   7-July-1993 (added AndrewBe's UnicodeAnsi conversion routines)
    KrishnaG        Added:   3-Aug-1993  (added DevMode/SecurityDescriptor dumps)

To do:

    Write a generic dump unicode string (reduce the code!!)
