#	List number of .aup and .wav files in track directories
#	Now lists the last line in */notes that starts with a nonblank in
#	column 1; this should normally be something about the most recent
#	semi-useable take.
#
# options:
#	-i  print key, meter, tempo, style info instead of track note.
#
# flags:
#	-  empty directory
#	n  "*/notes" present
#	N  "*/notes" has key: field (one hopes also style:, tempo:, meter:)
#	!  "*/OK" present
