+details="
+       Para_audiod supports three modes of operation: On, off and
+       standby (sb).  This option selects the mode that should be
+       used on startup. If para_audiod operates in \"on\" mode, it
+       will connect to para_server in order to receive its status
+       information. If para_server announces the availability of an
+       audio stream, para_audiod will automatically download, decode
+       and play the audio stream according to the given stream I/O
+       options, see below.
+
+       In \"standby\" mode, para_audiod will only receive the
+       status information from para_server but will not download
+       the audio stream.
+
+       In \"off\" mode, para_audiod does not connect para_server at
+       all, but still listens on the local socket for connections.

+#~~~~~~~~~~~~~~~~
+"well-known socket"
+string typestr="filename"
+optional
+details="
+       Para_audiod uses a \"well-known\" socket to listen
+       on for connections from para_audioc. This socket is a
+       special file in the file system; its location defaults to
+       /var/paraslash/audiod_sock.<host_name>.
+
+       para_audioc, the client program used to connect to para_audiod,
+       opens this socket in order to talk to para_audiod.  If the
+       default value for para_audiod is changed, para_audioc must be
+       instructed to use also \"filename\" for connecting para_audiod.
