Indices : Software : Design Applications : ConTeXt
ConTeXt is a document preparation system based on the TeX typesetting program. Being more recent than the other main TeX macro package, LaTeX, it is both more modular in its conception and more monolithic in its building.
This system was developed from 1990 by Hans Hagen from PRAGMA Advanced Document Engineering (Pragma ADE), a Netherlands-based company.
