+Volumectl: module

+	# 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.
