RR4 Linux and RR64 Linux are special DVDs that can transform your computer in a powerful Gentoo GNU/Linux box in less than 5 minutes. Gentoo GNU/Linux is a particular Linux flavour powered by a “software install manager” engine called Portage. What is an “Install Manager” ? It’s a software that installs and configure applications for you. RR4 Linux and its 64bit version, RR64 Linux, are completely installable on a plain Hard Drive. In this way you can touch with your hands the power of a Gentoo GNU/Linux Operating System without typing any mad shell commands.
