  22       set of well-known pager implementations are tried in turn, including

  25       no pager implementation is discovered no pager is invoked. Setting this environment variable to an empty string
  26       or the value <literal>cat</literal> is equivalent to passing <option>--no-pager</option>.</para></listitem>
