Just had a chat with Guha. He says you can have it under LGPL too if that
helps, no problem.

It might not be the one true RDF query syntax parser, but could save some
time so you can focus on the query system itself.

ps. Would be nice to (eventually) fold in some of the stuff later versions of
Squish do, at least the USING clause. Saves a bunch of typing and
seems to improve readability. For RDFdb if not for Redland too.
