Subject: * Package flag "keep" that prevents a package from being removed from
   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.)
