%% 
%% changed textwidths and margins to cope with printable area and
%% frame.  Make sure that the offsets are set to -1in!
%% Also changed scaling for a0->a4, since this was wrong.

%% This version changed by Hugh Pumphrey on 4.5.1999. Every instance
%% of the string ``draft'' replaced by the string ``preview''. This gives 
%% an a4 size preview but includes the postscript figures
