Module Name:

    main

Abstract:

    Trivial WinMain() function, creates tabbed dialog "property pages"
    and then creates the dialog... interesting code is in dialog procedures.

Author:

    Steve Firebaugh (stevefir)         31-Dec-1995

Revision History:

    SPORDER.EXE, DLL, & LIB were shipped in Win32 SDK along with NT4.

Comments:

    Code is generally ready to be compiled with UNICODE defined, however,
     we do not make use of this because EXE and DLL must also work on
     Windows 95.
