Gentoo is a highly flexible, source-based Linux distribution.
Unlike a binary software distribution, Gentoo Linux is compiled locally according to the user's preferences and is often optimized for the specific computer type. Precompiled binaries are available for some larger packages or those with no available source code.
Gentoo Linux was named after the fast-swimming gentoo penguin. The name was chosen to reflect the potential speed improvements of machine-specific optimization, a major feature of Gentoo. Gentoo package management is designed to be modular, portable, easy to maintain, and flexible. Gentoo describes itself as a meta-distribution because of its adaptability. The majority of users have configurations and sets of installed programs unique to the system and their applications.
