		| a user environment by an install or upgrade action.  This is
  particularly useful if you have a version installed that you don't
  want to upgrade (e.g., because the newer versions are broken).
  Example:
    $ nix-env -u zapping --dry-run
    (dry run; not doing anything)
    upgrading `zapping-0.9.6' to `zapping-0.10cvs6'
    $ nix-env --set-flag keep true zapping
    $ nix-env -u zapping --dry-run
    (dry run; not doing anything)
  However, "-e" will still uninstall the package.  (Maybe we should
  require the keep flag to be explicitly set to false before it can be
  uninstalled.) | ||
