% 23 May 1991: file created.
%
% 21 Jun 1991: Updated for the new module.sty.

% This is the module for importing the AMS A symbol font.
% It's pretty incomplete at the moment, and specifically doesn't
% understand the \substitutesymbols tag.
%
% But it's a start.

\@ifundefined{modulemoduleloaded}{\input module.sty}{}

% The first time the module is loaded, we grab the fonts.
