%description
This package contains machine-readable files for the SPIR-V Registry.
This includes:

  * Header files for various languages.
  * JSON files describing the grammar for the SPIR-V core instruction set and
    the extended instruction sets.
  * The XML registry file.
  * A tool to build the headers from the JSON grammar.
