**Indices : Software : Design Applications : TeX**

TeX, written as TeX in plain text, is a typesetting system created by Donald Knuth. It is popular in academia, especially in the mathematics, physics and computer science communities.

TeX is generally considered to be the best way to typeset complex mathematical formulas, but, especially in the form of LaTeX and other template packages, is now also being used for many other typesetting tasks.

ConTeXt and XeTeX are other macro-packages of TeX and is used for Desktop Publishing.
