	# a coloured result (green for good, red for bad, etc), and
	# the log file will have the time prefixed to the message and,
	# optionally, additional information messages after the main
	# message. All the messages are indexed in the language file.

	#		  [--screen-indent <n>] [--log-indent <n>]
	#		  [--nl [<n>]] [--nl-after] [--log-nl] [--screen-nl] [--nonl]
	#		  [--result <result> --color <colour>]
	#		  <message index> [optional message arguments]
	#
	# where the destination can be one of SCREEN, LOG or SCREEN+LOG.
	# The type can be one of PLAIN, INFO or WARNING.
	# The language file will have all the current values.
	#
	# The --screen-indent and --log-indent options are used to
	# forcibly indent a message.
	# The --nl option causes a blank-line to be output before the
	# message both on the screen and in the log file. A following
	# 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.
	# The --screen-nl option outputs a blank line on the screen
	# 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
	# lock file. It only applies to PLAIN messages, and may not be
