Hi All,

I'm afraid I'm not able to answer your query, but I remember quite
some time ago, I watched a thread that was exactly about that and I
saved one of the messages, so here it is, copied below my signature
file.

I hope this helps, but I don't know how much.
My recollection of this thread is that no one knew of a BNF version
of POV-Ray's scene description language.
Besides, the language is fairly flexible, and it may not be possible
to apply the formalism to it, simply because the formalism uses a
strict grammar.

Cheers,
Al.

You might check out libparpov at

It's not flex or bison, but it's a fairly complete parser from what
I've
heard.
