NAME
	receive_message - this_object() receives a message

SYNOPSIS
	varargs int receive_message(string class, string message, 
					mixed exclude)


DESCRIPTION
	This function is called when this_object() receives a message of a
	given class. The optional third argument should define objects
	to exclude. If config.h defines MUDOS_RECEIVE_MESSAGE, it will
	exist and call catch_tell(message, exclude) in the object. This
	function should return the number of objects receiving the 
	message.
