% NEW AUTHORHEAD LAYOUT for mm summer 1990
%
%              - The appearance of the author's information in the "from"
%                block on memoranda has changed. Also, the "x" extension
%                prefix has been removed; the complete phone number (with
%                area code) should be supplied as the 5th argument to the
%                .AU macro.  Given the author information:
%
%                .AU NAME [INIT] [LOC] [DEPT] [PHONE] [ROOM] [EMAIL] [ARG]
%                [ARG]
%                the "from" block for each author looks like:
%
%                NAME
%                Dept. DEPT
%                LOC ROOM
%                PHONE
