 878 alternate 3D APIs and non-Windows platforms.  The primary motivation is moving
 879 shaders to OpenGL languages on the fly.  The developer deals with \"profiles\"
 880 that represent various target languages, such as GLSL or ARB_*_program.
 881
 882 This allows a developer to manage one set of shaders, presumably written in
 883 Direct3D HLSL, and use them across multiple rendering backends.  This also
 884 means that the developer only has to worry about one (offline) compiler to
 885 manage program complexity, while MojoShader itself deals with the reduced
 886 complexity of the bytecode at runtime.
 887
 888 MojoShader provides both a simple API to convert bytecode to various profiles,
 889 and (optionally) basic glue to rendering APIs to abstract the management of
 890 the shaders at runtime.")
