FUNCTION

NAME
        say - Write a message to others than this_player().


SYNTAX
        void say(message)

DESCRIPTION
        This efun is deprecated. Use tell_room() instead.

	This efun will deliver the message to everyone in a location
	except this_player(). It is very hard to determine in a reliable
	fashion, what is this_player(), especially when monsters are
	involved.
