A collection of tools, libraries and tests for shader compilation. At the moment it includes: glslc (a command line compiler for GLSL/HLSL to SPIR-V), libshaderc (a library API for accessing glslc functionality), spvc (a command line wrapper around the SPIR-V to GLSL/HLSL/MSL compiler SPIRV-Cross), and libshaderc_spvc (a library API for accessing spvc functionality).
