 854 alternate 3D APIs and non-Windows platforms.  The primary motivation is moving
 855 shaders to OpenGL languages on the fly.  The developer deals with \"profiles\"
 856 that represent various target languages, such as GLSL or ARB_*_program.
 857
 858 This allows a developer to manage one set of shaders, presumably written in
 859 Direct3D HLSL, and use them across multiple rendering backends.  This also
 860 means that the developer only has to worry about one (offline) compiler to
 861 manage program complexity, while MojoShader itself deals with the reduced
 862 complexity of the bytecode at runtime.
 863
 864 MojoShader provides both a simple API to convert bytecode to various profiles,
 865 and (optionally) basic glue to rendering APIs to abstract the management of
 866 the shaders at runtime.")
