%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
