+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.
