#  Exit Status:
#	0	ok
#	1	error
#  Note:
#	Issue warning when BLOBIO_BIO4D_RRD_DURATION=0, otherwise the outp[ut
#	seems mysteriously stae.
#
#	Consider adding the disk usage of the volume storing
#	$BLOBIO_ROOT/data.  For gnu "df" do "df -h $BLOBIO_ROOT/data".
#
#	On gnu/linux sort is ignoring the second key.  The pain never ends.
