'''ConTeXt''' is a document preparation system based on the [http://en.wikipedia.org/wiki/TeX TeX] [http://en.wikipedia.org/wiki/typesetting typesetting] program. Being more recent than the other main TeX macro package, [http://en.wikipedia.org/wiki/LaTeX LaTeX], it is both more modular in its conception and more monolithic in its building. For instance, TeX-based vector graphics are fully integrated into ConTeXt through [[Metafun]], a superset of the [http://en.wikipedia.org/wiki/MetaPost MetaPost] graphic programming language (which in turn is derived from [http://en.wikipedia.org/wiki/Metafont MetaFont] language, another creation of [http://en.wikipedia.org/wiki/Donald_Knuth Donald Knuth]). It also focuses on using [http://en.wikipedia.org/wiki/PdfTeX PdfTeX] to generate both paper and on-line screen versions of the same documents. It comes with some [http://en.wikipedia.org/wiki/Perl Perl] utility scripts, like [[TeXutilTeXUtil]] and [[TeXexecTeXExec]].
