 * Enhancements
-	* Add new -t or --timeout option. If an audio source disappears without warning, the play session automatically terminates after a timeout period (default 120 seconds) and the device becomes available for new play requests again.
-This option allows you to set the timeout period in seconds. In addition, setting the timeout period to 0 means that play requests -- say from other devices on the network -- can interrupt and terminate the current session. In other words, the "busy" feature of the device -- being not available to another player while playing from an existing source -- is turned off. 
+	* Add new -t or --timeout option. Normally, when playing audio from a source, the Shairport Sync device is unavailable to other devices requesting to play through it -- it returns a "busy" signal to those devices. If the audio source disappears without warning, the play session automatically terminates after a timeout period (default 120 seconds) and the device goes from being "busy" to being available for new play requests again.

 	* Allow -B and -E commands to have arguments, e.g. -B '/usr/bin/logger "Starting to play"' is now legitimate.
