-** Enumeration tokens for SPIR-V, in various styles:
-** C, C++, C++11, JSON, Lua, Python
-**
-** - C will have tokens with a "Spv" prefix, e.g.: SpvSourceLanguageGLSL
-** - C++ will have tokens in the "spv" name space, e.g.: spv::SourceLanguageGLSL
-** - C++11 will use enum classes in the spv namespace, e.g.: spv::SourceLanguage::GLSL
-** - Lua will use tables, e.g.: spv.SourceLanguage.GLSL
-** - Python will use dictionaries, e.g.: spv['SourceLanguage']['GLSL']
-**
-** Some tokens act like mask values, which can be OR'd together,
-** while others are mutually exclusive. The mask-like ones have
-** "Mask" in their name, and a parallel enum that has the shift
-** amount (1 << x) for each corresponding enumerant.
