+<h2>JACK Connectivity</h2>
+
+<p>Polypaudio can be hooked up to a <a
+href="http://jackit.sourceforge.net/">JACK Audio Connection Kit</a> server which is a specialized sound server used for professional audio production on Unix/Linux. Both a
+Polypaudio sink and a source are available. For each channel a port is
+created in the JACK server.</p>
+
+<h3>module-jack-sink</h3>
+
+<p>This module implements a Polypaudio sink that connects to JACK and registers as many output ports as requested.</p>
+
+<table>
+ <tr><td><tt>sink_name=</tt></td><td>The name for the Polypaudio sink. If ommited defaults to <tt>jack_out</tt>.</td></tr>

+<h3>module-jack-source</h3>
+
+<p>This module implements a Polypaudio source that connects to JACK
+and registers as many input ports as requested. Takes the same
+arguments as <tt>module-jack-sink</tt>, except for <tt>sink_name</tt>
+which is replaced by <tt>source_name</tt> (with a default of <tt>jack_in</tt>) for obvious reasons.</p>
