- 2. License of the teTeX distribution as a compilation work
-
- The teTeX distribution, i.e. the tetex-base, tetex-extra and tetex-doc
- packages, together with the tetex-bin and tetex-src packages, is
- Copyright by Thomas Esser (1994-2005).
-
- The teTeX distribution is free software; you can redistribute it
- and/or modify it under the terms of the GNU General Public License as
- published by the Free Software Foundation; either version 2 of the
- License, or (at your option) any later version.

- Public License, which can be found in /usr/share/common-licenses/LGPL.
-
- - TeX, METAFONT:
-
- tex.web and mf.web have a special license; essentially, they are
- public domain, but no modified version may use the same name, and
- the names "TeX" and "MetaFont" for the resulting programs, unless
- they pass the TRIP and TRAP tests. Online, the complete license
- statement can be found in a text at
- http://www.ntg.nl/maps/pdf/5_34.pdf, and the relevant parts are:
-
- ,----
- | My work on developing TEX, METAFONT, and Computer
- | Modern has come to an end. I will make no further
- | changes except to correct extremely serious bugs.
- |
- | I have put these systems into the public domain so that
- | people everywhere can use the ideas freely if they wish.
- |
- | [...]
- | As stated on the copyright pages of Volumes B, D, and
- | E, anybody can make use of my programs in whatever
- | way they wish, as long as they do not use the names
- | TEX, METAFONT, or Computer Modern. In particular,
- | any person or group who wants to produce a program
- | superior to mine is free to do so. However, nobody is
- | allowed to call a system TEXor METAFONT unless that
- | system conforms 100% to my own programs, as I have
- | specified in the manuals for the TRIP and TRAP tests.
- | And nobody is allowed to use the names of the Computer
- | Modern fonts in Volume E for any fonts that do not
- | produce identical tfm files. This prohibition applies to
- | all people or machines, whether appointed by TUG or
- | by any other organization. I do not intend to delegate the
- | responsibility formaintainance of TEX, METAFONT, or
- | Computer Modern to anybody else, ever.
- `----
-
- For those who believe more in texts written on paper, we reproduce
- here the (identical) copyright page(s) of Volumes B and D of
- "Computers and Typesetting" by Donald E. Knuth, which present the
- commented code for TeX and METAFONT, respectively (the main text of
- these books can be obtained by "weave tex.web; tex tex.tex"):
-
- ,----
- | TeX is a trademark of the American Mathematical Society
- |
- | METAFONT is a trademark of Addison Wesley Publishing Company.
- |
- | The program for TeX is in the public domain, and readers may freely
- | incorporate the algorithms of this book into their own programs.
- | However, use of the name 'TeX is restricted to software systems that
- | agree exactly with the program presented here.

- 4. Text of the licenses
-
- The source code for tetex-bin contains the following license:
-
- The files within this directory are all free software. Most of these
- files are copyright by some author(s), but I have taken care that
- the following conditions are true:
- - all files can be distributed: no license fee is required.
- - using these files (even for commercial purpose) is not restricted.
- - modification of files is allowed or an existing translation scheme
- effectively makes modification unnecessary. E.g. Knuth's WEB files
- must not be changed, but the build process allows you to change
- the generated .c files by "change files". Please, check the license
- of a file before you do modifications; you might need to mark those
- modifications or to rename the program.
- - the distribution of modified files and subsets of these files is
- allowed, but please check the licenses if you do that.
-
- If you find any file that violates any of these conditions, please report
- that to me.
