Package Portage

Package management system based on ports collections.

https://wiki.gentoo.org/wiki/Project:Portage

Portage is a GPLv2 package management system based on ports collections. The Package Manager Specification Project (PMS) standardizes and documents the behavior of Portage so that the Gentoo packages can be managed by other package managers. Some alternative package managers for Gentoo include Paludis and pkgcore.
The goal of the Portage project is to provide a seamless integration of developer and user tools to aid the growth and maintenance of Gentoo packages. This means we work not only on Portage itself, but also on associated tools, and on ensuring that our APIs are useful to other tools.
