Great, I'm just tidying up what I have at the moment (not vast amounts). It includes some code from Ola berg too.
I like the idea of getting together a bit more of a detailed proposal first. We just need to ensure that we come back to the mailing list before too long, so as not to exclude anybody ;-) Stephen ----- Original Message ----- From: "Dmitri Plotnikov" <[EMAIL PROTECTED]> > I actually have some time I could dedicate to [clazz] right now.
