%description
AZSLc (Amazon Shading Language Compiler) is a stand-alone command-line
compiler that converts Amazon Shading Language (AZSL) shaders to High Level
Shading Language Shader Model 6+ (HLSL) shaders. It is the front-end
compiler of the Atom Renderer shader build pipeline used by Open 3D Engine
(O3DE). AZSLc extracts reflection data from .azsl files including shader
constants layout, resource binding information, and shader variant options.
