Like I said to LLH3, anything the computer can understand, the fanatic freaks
can read too...

Fortunately however, they aren't likely to be particularly interested, so just
trashing it a little will go a long way... (How long has the unshroud project

Anyway, I'm happy to leave the specifics to Craig. (And I think Craig is as
happy to have my punk kid nose out of it too...)
