This allows alternate ways to enable debugging. <code class="literal">NONE</code>
means no alternate methods are allowed. <code class="literal">URL</code>
means when the keyword <code class="literal">SMARTY_DEBUG</code> is found in the
<code class="literal">QUERY_STRING</code>, debugging is enabled for that
invocation of the script. If <a class="link" href="variable.debugging.html" title="$debugging">
<em class="parameter"><code>$debugging</code></em></a> is <code class="constant">TRUE</code>, this value is ignored.
