% The module for importing the St Mary's Road symbol font.

% Copyright 1991 Alan Jeffrey.

% 23 May 1991: file created.
%
% 25 May 1991: Updated for the new module.sty and stmaryrd.mf.
%
% 5 Jun 1991: By mistake, \varotimes wasn't swapped for \otimes.
%
% 25 Jun 1991: Added \longarrownot and \Longarrownot.
%
% 27 Jun 1991: The default is now for the defult circles, not the
% heavier ones.  If you want \oplus, \otimes, etc. to generate the
% heavier symbols, set the tag \heavycircles.

% This module loads in the St Mary's Road symbol font, and defines loads
% of new commands to access it.  It understands the tag \heavycircles
% to mean `please give me the heavy versions of \oplus etc.'  It
% can cope with new or obsolete font selection, but doesn't understand the
% \substitutesymbols tag yet.
