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