+        <para>This library mainly supports operations for asynchronous
+        communication to units on IEEE 1394 bus. Additionally, this library
+        supports some model-specific operations for some Audio and Music units
+        on IEEE 1394 bus, supported by drivers in ALSA firewire stack. This
+        library launches two threads internally to dispatch input events.</para>
