GL_EXT_Cg_shader???

I’ve just installed new dirvers from NVIDIA 61.77 for my GF4Ti4200 and found GL_EXT_Cg_shader among extension list…
Is anybody know what is this?
I didn’t found any info about this extension at
http://oss.sgi.com/projects/ogl-sample/registry/

EXT_CG_shader allows CG code to be compiled in GLSL…

where can i get specification of this extension?
where did you get this info?

I don’t think there is a spec around for download. What this extension does is known because people from nvidia have posted on this board as well as many others that have said what this extension is all about. I believe there was also an nvidia presentation that mentioned it too.
