[boost] graph_parallel

I notice that release branch now has libs/graph_parallel. I have a couple of questions about that: 1. I don't see any mention of this addition at http://beta.boost.org/users/news/version_1_40_0 Jeremiah, unless I've missed something, would you please add something to release notes? 2. Normally, directories under libs/ correspond to libraries. I do not see any review for new library called graph_parallel on: http://www.boost.org/community/review_schedule.html, which suggest to me this is actually part of Boost.Graph libraries. Why does it have top-level directory? Thanks, Volodya
