So, strictly speaking, emerge takes an atom and will install that. In 
this case, 'world' is the atom. 'emerge world' will REINSTALL every atom 
in your world file (.../var/lib/portage/world). The canonical way to 
UPDATE all packages is with the short options "-uDN", emerge -pvuDN 
world.

To break that down further, if you were trying to install 
'app-editors/vim' then 'emerge vim' would install vim the first time and 
keep reinstalling vim every subsequent time, but 'emerge -u vim' would 
only update vim if needed.

Hope that helps,
Jeremy
