I remember hearing Kirk talk about it as a future feature at FreeBSD CON last year, but I havn't heard anything about it since. How do you use it? Thanks, -brian p.s. Forgive me if this is well documented in -CURRENT. At the moment, the latest version of FreeBSD that I have available to me is 4.1-RC (cvsup from July 21) and I can't find any mention of it. -- Brian O'Shea boshea@ricochet.net To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-current" in the body of the message
