Module Name:

    lodctr.c

Abstract:

    Program to read the contents of the file specified in the command line
        and update the registry accordingly

Author:

    Bob Watson (a-robw) 10 Feb 93

Revision History:

    a-robw  25-Feb-93   revised calls to make it compile as a UNICODE or
                        an ANSI app.

    a-robw  10-Nov-95   revised to use DLL functions for all the dirty work

    // command line arguments supported:

    /C:<filename>   upgrade counter text strings using <filename>
    /H:<filename>   upgrade help text strings using <filename>
    /L:<LangID>     /C and /H params are for language <LangID>

    /S:<filename>   save current perf registry strings & info to <filname>
    /R:<filename>   restore perf registry strings & info using <filname>

    /T:<service>    set <service> to be Trusted using current DLL
