Hi, Certain manuals available at docs.openstack.org contain this legal notice: Copyright © 2013 OpenStack Foundation Licensed under the Apache License, Version 2.0 (the "License"); you may not use this file except in compliance with the License.

Can anyone clarify? We'd like to adapt some portions of the upstream documentation in our product documentation and we want to make sure we get the licensing right. Thanks!
