Hi, In the Boost distribution there is the file "boost.png" which contains the white-background version of the Boost logo. The distribution README says that all software & documentation without explicit copyright and license specification are licensed under the Boost Software License 1.0. I just wanted to ascertain that boost.png is indeed licensed under the BSL. See http://commons.wikimedia.org/wiki/Image:Boost.png for the cause of my question. While in many jurisdictions, usage of a logo for most reasonable purposes would be considered Fair Use, Commons requires an explicit free license. Regards Aristid Breitkreuz
