Sometime when i upgrade my gentoo i have many ebuilds to do and i simply do emerge -uDN world. Sometime i found some information from ewarn of the ebuild. I'm thinking, it's possible to add in portage one features, thats catch from ewarn all the text and send everything in one email ? So, when update is going, i can know everything is going. (ex last update of openssl is advisoring to do 4 steps, revdep-rebiuld and after delete old lib)
