# Short-Description: A purely functional package manager.
# Description:
# GNU Guix provides state-of-the-art package management features such as
# transactional upgrades and roll-backs, reproducible build environments,
# unprivileged package management, and per-user profiles. It uses low-level
# mechanisms from the Nix package manager, but packages are defined as native
# Guile modules, using extensions to the Scheme language—which makes it nicely
# hackable.
