% This style uses Times Roman as much as possible in math mode.

% May need further hacking, depending on the version of Times encoding
% that you use.  The version I use has the various capital Greek
% letters hacked in from Symbol.  This is not fully tested... it may
% be missing some other maths characters or text characters for TeX.
% Seems to be compatible with AMS-LaTeX.
% 
% Altered by Dave Laurenson (dil@castle.ed.ac.uk) to work with
% oldlfont.sty and 10pt, 11pt and 12pt document styles.
% The same changes also made by Sven Heemeyer. Thanks to both.

% merged together by S Rahtz July 1993
% ------------------------------------------------------------
% Known bugs:
% 
% Times italic maths characters should have their own TFM, AFM, etc, for
% better spacing of fonts.
% 
% Room for directly addressable maths mode fonts seems to be limited, I
% don't know why yet...
% 
% Postscript accents behave in a different way to CMR accents, so that
% there is \mathaccent fails.  Present correction merely replaces the
% Times accents with CMR ones.  Accents in maths mode should be Times accents.
