OpTeX: the LuaTeX format based on Plain TeX and OPmac Author: Petr Olsak, This software is in public domain. See http://petr.olsak.net/optex Files: base/ ... basic set of macro files used when optex.fmt is generated and more basic macros loaded on demand during document processing. demo/ ... examples: short document: op-demo.tex, short letter: op-letter.tex, presentation slides: op-slides.tex. pkg/ ... external macros. Maybe, they can be created by other authors if the macro file conforms to the rules given in the section 2.2.5 in the OpTeX documentation. doc/ ... PDF version of the OpTeX documentation and sources.
