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