% \section{Introduction}
%
%  This file provides support for the MathTime fonts from the
%  TeXplorators corporation for use with \LaTeXe.
%  There are a number of problems with using |\boldmath| within a subsection
%  statement. For this see the comments later on in this file.
% 
%  |\rmdefault| is the Times family.
%  |\sfdefault| is the Helvetia family.
%  |\ttdefault| is the Courier family.
%  These can be changed in the preamble by redefining the following:
%  \begin{verbatim}
%  \renewcommand{\sfdefault}{phv} % Times
%  \renewcommand{\rmdefault}{ptm} % Helvetica
%  \renewcommand{\ttdefault}{pcr} % Courier
%  \end{verbatim}

% The following  definitions give problems in the toc line. Comment

% one with all the definitions. The second with the following
% commented out. To obtain the final version one can use |\nofiles| and
