%description
Nix is a purely functional package manager. It allows multiple
versions of a package to be installed side-by-side, ensures that
dependency specifications are complete, supports atomic upgrades and
rollbacks, allows non-root users to install software, and has many
other features. It is the basis of the NixOS Linux distribution, but
it can be used equally well under other Unix systems.
