% This package aims at converting XyMTeX documents into PDF by 
% using the dvipdfm(x) converter or its equivalent. The codes 
% contained in xymtx-ps.dtx for the PostScript mode of XyMTeX 
% have been changed and extended to match direct conversion 
% into PDF files.

% \section{Input of basic macros}
%
% To assure the compatibility to \LaTeX{}2.09 (the native mode), 
% the commands added by \LaTeXe{} have not been used in the resulting sty 
% files ({\sf ccycle.sty} for the present case).  Hence, the combination 
% of |\input| and |\@ifundefined| is used to crossload sty 
% files ({\sf chemstr.sty} for the present case) in place of the 
% |\RequirePackage| command of \LaTeXe{}. 
% The global setting of unit by |\psset| has caused imcompatibility 
% with the prosper package and so has been changed into a local setting. 
% \changes{v4.03a}{2005/08/02}{Bug fix for the compatibility with 
%  the prosper package}
% \changes{v5.00b}{2010/11/23}{added the pgfcore package for pdflatex}
