%
% The option ``chemist'' is to load the \textsf{chemist} package in place of 
% the default loading of the \textsf{chmst-ps} package. By the option ``chemtimes'' 
% of the \textsf{chemist} or \textsf{chmst-ps} package, the switch \verb/\@chemtimestrue/ 
% or \verb/\@@@chemtimestrue/ becomes effective. Thereby, the mathversions ``chem'' and 
% ``boldchem'' defined in the \textsf{chemist} package are entirely ignored so as to be 
% replaced by those defined in the \textsf{chemtimes} package. 
%

% in place of the corresponding roman and san serif families.
