Editing ConTeXt (section)

==Example of code==
Making ConTeXt documents is simple: one makes a plain text file, and compiles it with the <code>context</code> script.<ref>[http://www.pragma-ade.com/general/manuals/mtexexec.pdf "TeXEXEC explained" manual. Pragma ADE.]</ref> The result of this process is a [[Portable Document Format|PDF]] file (ConTeXt also can generate a [[DVI (file format)|DVI]] file). An example is shown below.

ConTeXt documents come with the file extension .tex or an extension demarking the version required: <code>.mkii</code>, <code>.mkiv</code>, or <code>.mkxl</code> for regular TeX, <code>.mkvi</code> or <code>.mklx</code> for a dialect that supports named macro parameters in addition to TeX’s numeric ones.<ref>{{Cite web|url=https://mailman.ntg.nl/pipermail/ntg-context/2020/096906.html|title=[NTG-context] Official file ending?|last=Hagen|first=Hans|date=2020-02-04|website=mailman.ntg.nl|access-date=2020-02-12|archive-date=2021-06-28|archive-url=https://web.archive.org/web/20210628083507/https://mailman.ntg.nl/pipermail/ntg-context/2020/096906.html|url-status=dead}}</ref>

\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.
