This month edition of Gentoo Monthly Newsletter, the very first one of 2014, January 2014 tips a nice command as bonus:


$ emerge --moo

I didn’t know about that option and it’s not in emerge(1), must be an Easter egg.

Also a bonus tip for motd (message of the day), not sure about games-misc/dodge, it’s kind of overdoing the screen. I have my own motd from various sources of quotes.
