Cg wrapper?


Is there any Cg to OpenGL ES 2.0 wrapper existed? I’m asking because I’m reading nvidia’s GPUFFT which is implemented using Cg. I would like to port this to OpenGL ES 2.0. I know GLES2.0 has some limitation such as no multiple draw buffer (am I right?), so the code may not be “wrapper” directly. But I’m still curious if this wrapper make any sense? If yes, have anyone implemented this?
