Description:
A collection of tools, libraries and tests for shader compilation.

Shaderc aims to to provide:
- a command line compiler with GCC- and Clang-like usage, for better
integration with build systems
- an API where functionality can be added without breaking existing clients
- an API supporting standard concurrency patterns across multiple
operating systems
- increased functionality such as file #include support
