+define Package/shairport/description
+  This program emulates an AirPort Express for the purpose of streaming
+  music from iTunes and compatible iPods. It implements a server for the
+  Apple RAOP protocol.
+  ShairPort does not support AirPlay v2 (video and photo streaming).
+
+  It supports multiple simultaneous streams, if your audio output chain
+  (as detected by libao) does so.
