+		The DirectX Shader Compiler project includes a compiler and related tools used to compile High-Level Shader Language (HLSL) programs into DirectX Intermediate Language (DXIL) representation. Applications that make use of DirectX for graphics, games, and computation can use it to generate shader programs.
