ConTeXt is a document markup language and document preparation system based on the TeX typesetting system. It was designed with the same general-purpose aims as LaTeX of providing an easy to use interface to the high quality typesetting engine provided by TeX. However, while LaTeX insulates the writer from typographical details, ConTeXt takes a complementary approach by providing structured interfaces for handling typography, including 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 TeX macro language. ConTeXt’s unified design avoids the package clashes that can happen with LaTeX.
