Volumectl: module{	PATH:	con "/dis/lib/volume.dis"; 	# Volumectl should be spawned as a separate process from	# any process that desires volume control.  The parameters	# are a ref Context that provides volumectl with access to	# the display, a chan of int through which volumectl receives	# Ir->Enter, Ir->VolUP, or Ir->VolDN commands (others are	# ignored), and a string that names the specific volume to	# be controlled (typically "audio out").	# Volumectl exits upon receiving Ir->Enter.	# It displays a volume control slider when receiving either	# Ir->VolUP or Ir->VolDN.  The slider automatically disappears	# after a period of inactivity. 	volumectl:	fn(ctxt: ref Draw->Context, ch: chan of int, device: string);};
