+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.
