emerge sync writes this at the end: " * An update to portage is available. It is _highly_ recommended * that you update portage now, before any other packages are updated. * Please do so and then update ALL of your configuration files. " I suggest to add information what particular commandline should the user run. Update only portage? Or also the dependence? Should he use --deep? Should he use --newuse? Should he run revdep-reconf after update of the portage? I once updated portage on a production server and it destroyed both portage and gcc and made the system unusable anymore. So I guess this matter must be a bit tricky.
einfo does not replace 'man emerge' or any other user docs. Update portage means exactly what it says - update portage (emerge --update portage).
