Gentoolkit

gentoolkit is a collection of tools used by Gentoo Linux to administer and develop the Portage package management system. The tools are managed and installed by Portage itself; on a Gentoo Linux system one can install gentoolkit by issuing the following command: emerge gentoolkit.

The tools are split into two related packages: gentoolkit and gentoolkit-dev. As with the rest of Portage they are written in Python. The current versions are 0.2.4.2 and 0.2.6.8, respectively.
