ConTeXt is a general-purpose document processor. It is especially suited for structured documents, automated document production, very fine typography, and multi-lingual typesetting. It is based in part on the TeX typesetting system, and uses a document markup language for manuscript preparation. The typographical and automated capabilities of ConTeXt are extensive, including interfaces for handling microtypography, multiple footnotes and footnote classes, and manipulating OpenType fonts and features. Moreover, it offers extensive support for colors, backgrounds, hyperlinks, presentations, figure-text integration, and conditional compilation. It gives the user extensive control over formatting while making it easy to create new layouts and styles without learning the low-level TeX macro language. ConTeXt may be compared and contrasted with LaTeX, but the primary thrust of the two are rather distinct. ConTeXt from the ground up is a typography and typesetting system meant to provide users easy and consistent access to advanced typographical control—important for general-purpose typesetting tasks. The original vision of LaTeX is to insulate the user from typographical decisions—a useful approach for submitting, say, articles for a scientific journal. LaTeX has evolved from that original vision; at the same time, ConTeXt’s unified design avoids the package clashes that can happen with LaTeX.〔(FAQ of the UK TeX Archive )〕〔("What is ConTeXt" page at contextgarden )〕 ConTeXt provides a multi-lingual user interface with support for markup in English, Dutch, German, French, and Italian and support for output in many languages including western European, eastern European, Arabic-script, Chinese, Japanese, and Korean. It also allows the user to use different TeX engines like pdfTeX, XeTeX, and LuaTeX without changing the user interface.〔 As its native drawing engine, ConTeXt integrates a superset of MetaPost called MetaFun,〔 which allows the users to use the drawing abilities of MetaPost for page backgrounds and ornaments. Metafun can also be used with stand alone MetaPost. ConTeXt also supports the use of other external drawing engines, like PGF/TikZ〔(PGF/TikZ official manual. Version 2.0 ). Section 9.1.3 "Using the ConTeXt Format". p. 88〕 and PSTricks.〔(List of ConTeXt modules at contextgarden )〕 ConTeXt also provides a macro package for typesetting chemical structure diagrams with TeX called (PPCHTeX ),〔(PPCHTeX Module for ConTeXt reference page at contextgarden )〕 as well as many other modules.〔〔(List of ConTeXt modules (static page) )〕〔(List of ConTeXt modules in web server for downloading )〕 This package can also be used with plain TeX and LaTeX. Originally entitled pragmatex, ConTeXt was given its name around 1996.〔(Hans Hagen Interview, 2006 )〕 by Hans Hagen from (PRAGMA Advanced Document Engineering ) (Pragma ADE), a Netherlands-based company. == License == ConTeXt is free software: the program code (i.e. anything not under the /doc subtree) is distributed under the GNU GPL; the documentation is provided under Creative Commons Attribution NonCommercial ShareAlike license.The ConTeXt (official manual )(2001) and ConTeXt (official mini tutorial ) (1999) are documents copyrighted by Pragma, but there is a repository of the future new manual〔(Repository of new reference manual )〕 released under the GNU Free Documentation License.〔(License notice of new official manual )〕〔Part of thread about context manual where Taco Hoekwater (recognises that new manual is licensed under the GFDL ) and (he should put license note on the current directory of manual )〕 As of April 2009 there is an up-to-date version of the fonts and typography chapters.〔Up-to-date chapters of manual: (Fonts ) and (Typography ).
