Vulkan-Docs/COPYING.md

The files in, and generated output documents from this Vulkan-Docs project are under a mix of copyright and license statements. Refer to the individual files for specific information. As a general guideline:

• The Vulkan Specification asciidoc sources and generated output documents are under a proprietary Khronos license. See https://www.khronos.org/registry/speccopyright.html
• The Vulkan headers, spec build tools, and spec and registry configuration files are for the most part under the Apache 2 license. Some older files under BSD-like licenses which may eventually be updated to Apache 2 as we have time.
• There may be some configuration files customized from material shipped with the asciidoc and dblatex distributions. Such files continue under their original copyrights.
• Documentation which we expect to be redistributed in different formats, such as the reference pages generated from the Specification source, are under a Creative Commons Attribution 4.0 license.
• Some generated, transient files produced during the course of building the specification, headers, or other targets may not have copyrights. These are typically very short asciidoc fragments describing parts of the Vulkan API, and are incorporated by reference into specification or reference page builds.
• If something is missing a copyright statement and that poses an actual problem for whatever you're doing, file an issue on GitHub and we'll eventually correct it in some fashion.

Working with the different Khronos member company IP lawyers to make license changes is a very slow process constrained by the Khronos Member Agreement and IP Policy as well as by individual company concerns about their IP. Do not expect rapid changes in anything having to to with copyrights and licensing.
