[boost] GSoC Doc Camp

Google sent an email to the GSoC mentors list to invite to a GSoC Doc Camp - see https://sites.google.com/site/docsprintsummit/. It's five days in October just before the GSoC Mentor Summit starts. Those wishing to attend do not need to be from a GSoC project. As the application deadline is this Friday, hurry up if you are interested. Boris
