% \section{Dummy Declarations}
% If a document written for the PostScript or PDF mode is processed by the TeX/LaTeX mode, 
% some commands for the PS or PDF mode (defined in the \textsf{xymtx-ps} or \textsf{xymtx-pdf} 
% package) cause errors of non-existence. To avoid these errors, 
% dummy commands are defined as follows. These dummy commands are overwritten or replaced by 
% equivalent commands when processed by the PS or PDF mode.
