#
# Message services: formatting a message based on information from a
# hinfo object and the class, and some standard messages.

# Format messages by stirring them with a dictionary of information for use
# in Python-style format strings. The dictionary is drawn from hostinfo and
# class data.

	d = hi.getinfo()

	# Give the user some way to insert \r, \n, and \r\n.
	d['cr'] = "\r"; d['nl'] = "\n"; d['eol'] = "\r\n"
	# We cannot mutate sdict, so we use a new dictionary (rd, the
	# root dictionary) to get the semantics we want, which is that
	# sdict cannot override values from elsewhere if they exist.
	# (This means we put sdict in first, then d in later.)
