<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>
