CAL Programming

Hi All

I was wondering if there are any good references for learning how to program CAL files in Radiance. I have the book "Rendering with Radiance" but it seems to be void of any in-depth information concerning writing procedurals with the CAL files. I have tried to go through the files to see how they are written but unfortunately, I can't understand how many of the equations were derived. The reason why I would like to know is so that I can write my own procedurals and so that I can better optimize the parameters for the standard cal files.
