following command-line options:</p>
<ul>
+ <li>
+ <p><span class="emphasis"><i class=
+ "EMPHASIS">--config-test</i></span></p>
+
+ <p>Exit after loading the configuration files before binding to the
+ listen address. The exit code signals whether or not the
+ configuration files have been successfully loaded.</p>
+
+ <p>If the exit code is 1, at least one of the configuration files
+ is invalid, if it is 0, all the configuration files have been
+ successfully loaded (but may still contain errors that can
+ currently only be detected at run time).</p>
+
+ <p>This option doesn't affect the log setting, combination with
+ <span class="emphasis"><i class="EMPHASIS">--no-daemon</i></span>
+ is recommended if a configured log file shouldn't be used.</p>
