for example: "emerge --update (--deep) world" builds a lot of packages. many ebuilds seem to have instructions included that tell the user, what they should do next with the emerged package (e.g.: alsa). those (i guess with a yellow asterix marked) user information should be printed out at the very end of an "emerge --update (--deep) world" or/and saved to a seperate file.
