\title{\ConTeXt}
 
\section{Text}
\ConTeXt{} 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 (for example
to equation \in[eqn:famous-emc]), tables and figures, page layout,
bibliographies, and much more.
 
It was originally written around 1990 by Hans Hagen. It could be an
alternative or complement to \LaTeX.
 
\section{Maths}
With \ConTeXt{} we could write maths. Equations can be automatically numbered.
