<li>Extensible plugin architecture (by loading dynamic loadable modules with <tt>dlopen()</tt>)</li>

<h2><a name="status">Status</a></h2>
<p>The best idea is to configure your daemon in <tt>/etc/polypaudio/daemon.conf</tt> and <tt>/etc/polypaudio/default.pa</tt> and to run polypaudio without any arguments.</p>
+<p><b>Beware!</b> Unless you pass the option <tt>--sysconfdir=/etc</tt> to
+<tt>configure</tt>, the directory <tt>/etc/polypaudio/</tt> is really
