ZzTeX Macro Package, version 17.7 The ZzTeX macro package is a full-featured TeX macro package specially designed for producing books, journals, and manuals. Development of the package began in 1989. Since then, about 500 textbooks and journals have been produced with it for a variety of publishers. Numerous authors have used the package to produce subsequent editions of their books. I provide the TeX files for ZzTeX under The MIT License. You may use any or all of the code for whatever purpose you desire. ZzTeX runs under Plain TeX. The only documentation available for the package is contained in the zz*.dat files that accompany the TeX files. I hope you find some of the code useful for your TeX projects.
