LuaTeX is a TeX-based computer typesetting system which started as a version of pdfTeX with a Lua scripting engine embedded.

After some experiments it was adopted by the TeX Live distribution as a successor to pdfTeX (itself an extension of ε-TeX, which generates PDFs).

[6] A related project is MPLib (an extended MetaPost library module), which brings a graphics engine into TeX.

[7] The LuaTeX team consists of Luigi Scarso, Taco Hoekwater, Hartmut Henkel and Hans Hagen.

[8] As of October 2010[update], both ConTeXt mark IV and LaTeX with extra packages (e.g. luaotfload, luamplib, luatexbase, luatextra) make use of new LuaTeX features.
