34    @remarks
35        Note that the syntax of D3D9 HLSL is identical to nVidia's Cg language, therefore
36        unless you know you will only ever be deploying on Direct3D, or you have some specific
37        reason for not wanting to use the Cg plugin, I suggest you use Cg instead since that
38        can produce programs for OpenGL too.
