+SYNOPSIS

+   void catch_msg(mixed *arr, object obj)
+
+
+DESCRIPTION
+===========
+
+   When say(), tell_object()  or tell_room() are used with an array
+   as message, the array will be passed to catch_message() in all living
+   objects that can hear it, instead of writing to the user resp.
+   sending to catch_tell(). This can be used to implement
+   communication protocols between livings. The second denotes
+   the object that has sent the message.
