description     NVIDIA's Cg high-level shading language

long_description \

    Cg (short for C for Graphics) is a high-level shading language \

    developed by Nvidia in close collaboration with Microsoft for \

    programming vertex and pixel shaders.  It is very similar to \

    Microsoft's HLSL.  Cg is based on the C programming language and \

    although they share the same syntax, some features of C were \

    modified and new data types were added to make Cg more suitable \

    for programming graphics processing units.  This language is only \

    suitable for GPU programming and is not a general programming \

    language.  The Cg compiler outputs DirectX or OpenGL shader \

    programs.
