 962       (description "MojoShader is a library to work with Direct3D shaders on
 963 alternate 3D APIs and non-Windows platforms.  The primary motivation is moving
 964 shaders to OpenGL languages on the fly.  The developer deals with \"profiles\"
 965 that represent various target languages, such as GLSL or ARB_*_program.
 966
 967 This allows a developer to manage one set of shaders, presumably written in
 968 Direct3D HLSL, and use them across multiple rendering backends.  This also
 969 means that the developer only has to worry about one (offline) compiler to
 970 manage program complexity, while MojoShader itself deals with the reduced
 971 complexity of the bytecode at runtime.
 972
 973 MojoShader provides both a simple API to convert bytecode to various profiles,
 974 and (optionally) basic glue to rendering APIs to abstract the management of
 975 the shaders at runtime.")
