What makes you think you would have better luck if it was in C, embedded 
in the POV-Ray source code?

The user won't have to look at the macro, ever. They will just look in 
the documentation, see it in the section on "Pattern Macros", and learn 
how to use it in the same way they learn the built-in patterns. However, 
someone who wants to know how it is done simply has to open an .inc file 
and look at the appropriate macro. *They* are the ones who will see the 
macro and want to modify it, not the ordinary users. The only thing they 
will have to do is #include "patmacs.mcr" and put a macro call where 
they would otherwise put a keyword.
