[boost] [GitHub] List open pull requests for all libraries? [resend]

We need to be able to monitor the open pull requests for all Boost libraries, not just a individual library. I'm not seeing any canned way of doing that via the GitHub web site. Am I missing something? It does seem possible to access the required information via the GitHub API. Is that the best approach to take? Does anyone know how to do this? Thanks, --Beman
