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.
