I haven't extended _reg_options_. However, since ATL.Registrar lacks
an automation interface I have whipped up a wrapper that provides
access to two of Registrar's methods.

The following fragment is a typical usage:

    UseCommandLine ( WebPASSCOMServer )
    from win32com.client import Dispatch
    from sys import argv
    registrar = Dispatch ( 'RegistrarCOMWrapper.Register' ) 
    regString = \
'''
HKCR
{
    NoRemove 'CLSID'
    {
        ForceRemove '{D471BE26-C3C8-4773-B438-041BA612C563}'
        {
            'Implemented Categories'
            {
                '{7DD95801-9882-11CF-9FA9-00AA006C42C4}'
                '{7DD95802-9882-11CF-9FA9-00AA006C42C4}'
            }
        }
    }
    NoRemove 'Component Categories'
    {
        NoRemove '{7DD95801-9882-11CF-9FA9-00AA006C42C4}'
        NoRemove '{7DD95802-9882-11CF-9FA9-00AA006C42C4}'
    }
}
'''
    // following lines parallel the way 'UseCommandLine' works
    if '--unregister' in argv: registrar . StringUnregister (
regString )
    else: registrar . StringRegister ( regString )

To me, the nice thing about this approach is that it involves the use
of the '.rgs' scripts that are familiar to people who work with MSVC.

I have done only very limited trials, on Win2K at that. Would welcome
comment, including a suggestion of where I might put this ugly thing
in case someone else might consider using it.
