Help starting with nyacc

[Mike Gran]

Hello all-

I sincerely apologize that this is a "please do my work for me" email,
but, I don't know too much about LALR parsing outside of Ragel. I have
the following excerpt of a grammar that I've extracted from an ECMA-48
parser I wrote in Ragel, and I'd like to port it over to Guile via
NYACC.  I think if someone could help me get the skeleton right, I
could carry on from there.

The Ragel parser (greatly edited) follows.

Thanks in advance!

Mike Gran
