Arch Linux is a lightweight and flexible linux distribution that tries to Keep It Simple.

Official packages optimized for the i686 and x86-64 architectures are available. We complement our official package sets with a community-operated package repository that grows in size and quality each and every day.

This Ohloh project tracks all our projects except package repositories and AUR webinterface.
