LaTeX is a high-quality typesetting system; features are designed for the production of technical and scientific documentation. It’s the de-facto standard for the communication and publication of scientific documents, and available as free software. LaTeX is actually built on the TeX typesetting system created by the legendary Donald Knuth. LaTeX is nothing more than a series of TeX macros, providing ready made commands for common formatting and layout needs, such as section headings, footnotes, bibliographies and cross references.
