	# The language file will have all the current values.
	#
	# The --screen-indent and --log-indent options are used to

	# number can be used to indicate how many blank lines should
	# be displayed on the screen.
	# The --log-nl option outputs a blank line only in the log file.

	# regardless of whether SCREEN was specified or not.
	# The --nl-after option outputs a blank line on the screen after
	# the message.
	# The --nonl option is only to be used in special cases where we
	# want the output of more than one message to appear on the same
	# line. This is currently only used when trying to obtain the
