Translations:Ebuild repository/2/en

Within Gentoo Linux, users already have one "main" package repository, in the past synonymously referred to as the "Portage tree", although this term should be phased out since package managers other than Portage can interact with package repositories in Gentoo. The main repository contains all the software packages (called ebuilds) maintained by Gentoo developers. Additional package trees are usually hosted by repositories. Users can add such additional repositories to the tree that are "laid over" the main tree - hence the name, overlays.
