[boost] boost library incubator planning shutdown

I had high hopes for the boost library incubator when I made it. But I think it's pretty clear that those hopes haven't been realized. Maintaining and Enhancing this website required more effort than I had anticipated so it hasn't evolved. I do notice that people do use it from time to time (a couple hundred page hits/day), so it's not totally dead. But it would either have to go forward or be shut down. If someone wanted to take it over that would be fine. But I don't expect anyone to come forward so I'll be shutting it down probably in the next 30 days or so. Robert Ramey
