single derivation specified by the argument. This is useful when we want to have a profile for a single derivation, such as a server configuration. Then we can just say (e.g.) $ nix-env -p /.../server-profile -f server.nix --set -A server We can't do queries or upgrades on such a profile, but we can do rollbacks. The advantage over -i is that we don't have to worry about other packages having been installed in the profile previously; --set gets rid of them.
For installation and usage instructions, please read the manual, which can be found in `docs/manual/manual.html', and additionally at the Nix website at <http://www.cs.uu.nl/groups/ST/Trace/Nix>.
