+catch_tell()
+============
+
+SYNOPSIS
+--------
+::
+
+	void catch_tell(string)
+
+DESCRIPTION
+-----------
+::
+
+	When a message is sent to a noninteractive player, via say(),
+	tell_object, tell_room(), printf() or write(), it will get to the
+	function catch_tell(string). This will enable communications between
+	NPCs and from a player to an NPC.
+
+	Also, if an interactive object is being shadowed and the
+	shadow has catch_tell() defined, it will receive all output
+	that would otherwise be written to the user.
+
+	If a message is sent by an interactive object, catch_tell() is
+	not called in that object, to prevent recursive calls. Thus
+	catch_tell() in interactive objects can be used to filter the
+	output that goes to the users.
+
+	The efun shout() sends to interactive objects only.
