      <dt>Check Configuration Hook Added</dt>

      <dd>A new hook, <code>check_config</code>, has been added which runs

          between the <code>pre_config</code> and <code>open_logs</code>

          hooks.  It also runs before the <code>test_config</code> hook

          when the <code>-t</code> option is passed to

          <program>httpd</program>.  The <code>check_config</code> hook

          allows modules to review interdependent configuration directive

          values and adjust them while messages can still be logged to the

          console.  The user can thus be alerted to misconfiguration problems

          before the core <code>open_logs</code> hook function redirects

          console output to the error log.</dd>
