# HISTORY:
#	Oct 14, 2011: - created
#	Oct 15, 2011: - added nsamp
#	Oct 16, 2011: - made depth tic-marks range dependent
#	Oct 17, 2011: - turned into filter
#				  - added %run_label
#	Nov 14, 2011: - added file layout check
#	Mar 12, 2012: - sh -> ksh as this does not work with /bin/sh on MacOSX 10.6.4
#   Apr 12, 2012: - made re-entrant
#	May 15, 2013: - BUG: plot separation lines/shading did not work any more
#   Oct 30, 2103: - got rid of non-portable echo -e
