Vulkan^(R)^ API Documentation Project
=====================================
This repository contains formal documentation of the Vulkan API. This
includes the main API Specification, the reference (man) pages, the XML API
Registry, and related tools and scripts.
Single-Branch Model
-------------------
As of the 1.0.25 release, we have switched to a new "`single-branch`" model
in which all extensions are included in the source of the 1.0 branch of the
Specification, and can be configured in or out of the build using Makefile
options.
Repository Structure

Building the Specification and Reference Pages
----------------------------------------------
As of the 1.0.40 release, we have moved from the old `asciidoc` toolchain to
a new one based on `asciidoctor`. See `doc/specs/vulkan/README.adoc` for
more information on installing the toolchain and building the Specification.
Generating Headers and Related Files
------------------------------------
The header file (`src/vulkan/vulkan.h`) and many parts of the specification
and reference page documents are generated from descriptions in the XML API
Registry (`src/spec/vk.xml`). The generated files, with the exception of
`vulkan.h`, are not checked into the repository. If you change `vk.xml`, you
can regenerate the header by going to `src/spec` and running:
$ make clobber install
The other generated files are built as required via dependencies in
`doc/specs/vulkan/Makefile` .
