Packages that are part of the world set will always * be kept. They can be manually added to this set with * `emerge --noreplace <atom>`. Packages that are listed in * package.provided (see portage(5)) will be removed by * depclean, even if they are part of the world set. * * As a safety measure, depclean will not remove any packages * unless *all* required dependencies have been resolved. As a * consequence of this, it often becomes necessary to run * `emerge --update --newuse --deep @world` prior to depclean.
