Ah yes, I recall the copy now.

Sounds good. I didn't need it, so didn't put it, but if you do - go ahead.

It is doubtful that users of the parser will normally need this. Advanced
users would - who write their own scanners. We'd probably like them to know
something about the internals - not too much of course. Striking the right
balance is hard. Its always good to revisit a problem. Now that you know
what you do, what do you think is the minimum and simplest, given that you
don't want to lose performance ? (You are in the advanced user category now)

Hmm.. I seem to have misplaced them (apologies). Can you mail them to
Derrick ?
Derrick-> Dhaval is inside a firewall, and does not have access to our CVS
repository.
