+	  JACK Audio Connection Kit (JACK 1 implementation).
+
+	  JACK is a low-latency sound server, allowing multiple
+	  applications to connect to one audio device, and to share
+	  audio between themselves. This package contains the daemon
+	  jackd as well as some example clients.
+
+	  http://jackaudio.org/
+
+	  Another implementation (BR2_PACKAGE_JACK2) is also available,
+	  please consult the documentation to choose the right one:
