Please note that the content of this book primarily consists of articles available from Wikipedia or other free sources online. The W3C Software Notice and License is a permissive free software licence used by software released by the World Wide Web Consortium, like Amaya. The license is a permissive license, compatible with the GNU General Public License. A permissive free software licence is a free software license that applies to an otherwise copyrighted work. It also offers many of the same rights found in free software licenses when releasing a work to the public. In contrast to non-permissive copyleft (reciprocal) licenses such as the GNU General Public License, any copies and derivatives of the source code created under permissive licenses may be made available on terms that are more restrictive than those of the original license. For example, source code released under a permissive software license does not have the requirement that all distributed derivatives also be made available to the public.
