\section{\TeX\ and \LaTeX}

\TeX\ is a kind of text processing systems and was developed by 
{\em Donald Knuth}.  
One day, Knuth attempt to published his book and sent a draft of 
the book to a publishing company.  
Knuth received a test print of the book from the publishing 
company, but he was {\bf not satisfied with the format of the book} and 
sent his request of improvements to the company.  
A revised version of the test print still had points to be improved, 
and he had to make contacts with the publishing company many times.  

Finally, Knuth noticed he need a text processing system, with which 
he can make his book as he like, to avoid too long time for the 
contacts with the publishing company and to reflect his idea 
precisely to the book format.  
Then, Knuth made {\large the text processing system \TeX}.
