            <h2>Helpful Hints</h2>
            <h3>Debug Trace and Logging</h3>
            <p>GoAhead has a debug logging and trace facility that can help when debugging configuration issues or
            developing your application code that uses GoAhead. You can vary the level of logging via the <b>--log
            logfile</b> command line switch for the <b>goahead</b> commands. The log command line switch has the
            format:</p>
                <pre class="ui code segment">
goahead --log logFile:logLevel
</pre>
            <p>Use the <em>-v</em> switch to trace to the standard output at level 2.</p>
            <pre class="ui code segment">
goahead -v
</pre>
            <p>The log level can be from 0 to 9, with 9 being the most verbose level.</p>
