I've uploaded an early version of my configuration tool so that others can play with it. It's available from my web site.
Please download any play with it and do not forget to report bugs back to me. At this stage, I'm sure there are plenty of them. I'm also happy to take patches if I'm missing features or you find behavior annoying.
Chris Davies' software is much more mature than mine, so I'll probably switch over to using his once he releases it. But, you can all at least play with my version for now.
