+    (description " Apulse provides an alternative partial implementation of
+the PulseAudio API.  It consists of a loader script and a number of shared
+libraries with the same names as from original PulseAudio, so applications
+could dynamically load them and think they are talking to PulseAudio.
+
+Internally, no separate sound mixing daemon is used.  Instead, apulse relies
+on ALSA's dmix, dsnoop, and plug plugins to handle multiple sound sources and
+capture streams running at the same time.  dmix plugin muxes multiple playback
+streams; dsnoop plugin allow multiple applications to capture from a single
+microphone; and plug plugin transparently converts audio between various
+sample formats, sample rates and channel numbers.")
