4. (incomplete) list of licenses of individual parts

- kpathsea:

  libkpathsea is distributed under the terms of the GNU Library General
  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.

5. 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.
