Hi John, I'd suggest that both approaches can be somewhat lacking in portability. The command line is something of a kludge, IMHO, as it still depends largely on users typing in the correct parameters. I think ini files would be portable across a much wider variety of systems. Just write the ini file per installation configuration.
