The [[TeX]] system, developed by [[Donald E. Knuth]] at the end of the 1970s, is another widespread and powerful automated typesetting system that has set high standards, especially for typesetting mathematics. [[LuaTeX]] and LuaLaTeX are variants of TeX and of [[LaTeX]] scriptable in [[Lua (programming language)|Lua]].  TeX is considered fairly difficult to learn on its own, and deals more with appearance than structure. The LaTeX macro package, written by [[Leslie Lamport]] at the beginning of the 1980s, offered a simpler interface and an easier way to systematically encode the structure of a document. LaTeX markup is widely used in academic circles for published papers and books. Although standard TeX does not provide an interface of any sort, there are programs that do. These programs include [[Scientific Workplace]] and [[LyX]], which are graphical/interactive editors; [[GNU TeXmacs|TeXmacs]], while being an independent typesetting system, can also aid the preparation of TeX documents through its export capability.
