# Dump CD audio on disk (in AIFF format; stereo, 16 bit samples, 44.1 kHz).
#
# Each argument is either a track to play or a quoted 7-tuple:
#	'(track, min1, sec1, frame1, min2, sec2, frame2)'
# to play the track from min1:sec1:frame1 to min2:sec2:frame2.
# If track is zero, times are absolute instead.
