 \maketitle 
 \LaTeX{} is a document preparation system for the \TeX{} 
 typesetting program. It offers programmable desktop publishing 
 features and extensive facilities for automating most aspects of 
 typesetting and desktop publishing, including numbering and 
 cross-referencing, tables and figures, page layout, bibliographies, 
 and much more. \LaTeX{} was originally written in 1984 by Leslie 
 Lamport and has become the dominant method for using \TeX; few 
 people write in plain \TeX{} anymore. The current version is 
 \LaTeXe.

 % This is a comment; it is not shown in the final output.
 % The following shows a little of the typesetting power of LaTeX
 \begin{align}
   E &= mc^2                              \\
   m &= \frac{m_0}{\sqrt{1-\frac{v^2}{c^2}}}
 \end{align}
