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