[Mesa3d-dev] Adding vertex / fragment program functionality?

[Ian R. <id...@us...>]

Is there any documentation available for adding functionality to vertex 
/ fragment programs?  Specifically, I'm messing around with adding a new 
texture target, and I want to enhance the TEX et. al. instructions to be 
able to use that target.  It looks like the arbprogram.syn file needs to 
be updated, and that file is then used to generate some other files. 
How is that done?
