I meant: please let's publish some of those other grammar formats as
part of this WD. I gather your +1 is to a different idea.

I suppose it's not 100% critical to include other grammar formats
in the WD, but it seems odd to ask people to cut-and-paste the
grammar rather than having a machine consume it directly as
source code from the WD.

That's also useful.

Do you still have the bison, yacc, and perl-based parsers that you
got from Yacker? If so, please mail them to me with a copy to
www-archive and I'll add links from SparqlImplementations.
