Hello

Last month, I took a look at FreeBSD which really surprised me. However,
gentoo rocks so much I can't give it up. I started yesterday to create a
shell script that would help newbies with Gentoo, and especially
PORTAGE.
This script would be very similar to /stand/sysinstall of Freebsd. Are
there some volonteers to work on it with me ? 

(script is attached, don't worry about filename.)
