\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.
