void catch_tell( string message );
If INTERACTIVE_CATCH_TELL is defined in options.h, whenever the driver has something to tell an object due to say(), shout(), tell_object(), etc. catch_tell in the player object will be called with the message to be printed. The message can be displayed, discarded, or modified in any way desired. This is a useful way to have flexible earmuffs, or to support intelligent clients.
