%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.

See the README.fedora.md file for setup instructions.
