1. Copyright and License of the debian-specific adaptations

Debian adaptations for this Package are under Copyright by:

    Christoph Martin christoph.martin@uni-mainz.de (1998-2002)
    Adrian Bunk <bunk@fs.tum.de> (2000-2002)
    C.M. Connelly <cmc@debian.org> (2002)
    Atsuhito KOHDA <kohda@debian.org> (2002-)

    Frank Kster <frank@kuesterei.ch> (2003-)
    Florent Rougon <f.rougon@free.fr> (2004)

This list has been compiled in July 2004, therefore it is probably
incomplete (missing names and too short date ranges). Contributors of
translations and other small patches are mentioned in
changelog.Debian. 

The package was downloaded from CTAN:/systems/unix/teTeX

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.

On Debian GNU/Linux systems, the complete text of the GNU General Public
License may be found in /usr/share/common-licenses/GPL.

3. (incomplete) list of licenses of individual parts

The GPL applies to the teTeX distribution as a compilation work.
Individual parts of this distribution have their own copyright and
license.

We are attempting to provide comprehensive information on the licenses
of all files in the package, but this is ongoing work. Below you can
find a list of packages grouped by their license. (A "package" in this
sense is a bunch of files on the CTAN servers, usually one
subdirectory, with common copyright; the files in a package may be
installed in different locations in below /usr/share/texmf.) In the
accompanying file Copyright.Files you can find a list of files that
belong to each package. The actual text of the licenses (or a
reference to a separate file) is given at the end of this file
(copyright). The first file of a package's filelist is the file that
contains the license statement. If the license statement has been
found elsewhere (e.g. in a file that is not installed), the source of
information is stated in lines commented with #.


Therefore, if you want to know the license of a specific file, first
look up the package it belongs to in Copyright.Files, and then the
license of the package in this file, and it's text below. If you
cannot find the file in Copyright.Files, this means we did not yet
have time to look up it's license and include it in the list. In this
case, you have to look up the license: Often it is in the file itself,
sometimes you have to find out which package it belongs to, and look
into the file that describes it's license information (a file named
README, COPYING or similar). In some cases, the license information
may not be included any file installed with tetex-base, tetex-extra or
tetex-doc, but in the source in the tetex-src package.

If you had to figure out the license of a file or package this way,
please submit your results as a bug report, so that we can include it
here - thanks in advance!

The format of the list is

[Package|File]: License-abbreviation version[+]

Files or packages marked with a + have a "or later" versioning
clause. Packages with non-common licenses have a number instead of a
license abbreviation after their name, and the text of the license is
given below in section 4, ordered by the number. However, we have
tried to classify those individual licenses. Therefore you will find
entries like "cite: PD (1)" meaning that the file is in the Public
Domain, and the license is given as number 1.

A. Packages with unclear or problematic licenses

- euler: LPPL according changelog, but no indication in file.

- listings: LPPL, plus: 

,----
| *Modification*advice* 
| 
| Permission is granted to modify the listings package as well as
| lstdrvrs.dtx. You are not allowed to distribute a modified version of
| the listings package or lstdrvrs.dtx unless you change the file names
| and provide the original files. In any case it is better to contact
| the address below; other users will welcome removed bugs, new
| features, and additional programming languages.

This is more restrictive than LPPL 1.3 (6.a and 6.d.2). The title is advice... 

- ae: Just a formal problem, the GPL is included, but nowhere is it
      explicitly stated that this license applies to the package.

  cahyph.tex: LPPL 1+

4. Text of the licenses

A. GPL (Gnu General Public License)

On Debian GNU/Linux systems, the complete text of the GNU General Public
License can be found in /usr/share/common-licenses/GPL.

B. LPPL (LaTeX Project Public License)

The full text of the LPPL is given in
/usr/share/doc/tetex-base/lppl.txt.gz 

C. Artistic license

On Debian GNU/Linux systems, the complete text of the GNU General Public
License can be found in /usr/share/common-licenses/Artistic

D. PD (Public domain):

The file or package contains a statement equivalent to 

"This file is in the public domain. You may freely use, modify or
distribute it".

E. mBSD (modified BSD)

This abbreviation is used for BSD-type licenses if the only difference
to the original BSD license is that the text "the name of the
University nor the names of its contributors" has been changed to
something reflecting the authorship of the respective package.

X. Non-standard licenses, by number:

(1) These macros may be freely transmitted, reproduced, or modified
    provided that this notice is left intact.

(2) You may use and distribute these fonts as you like.
    You may modify these fonts as long as you do not
    rename the files to one of those names that 
    Donald E. Knuth chose for the Computer Modern fonts.
    (And seriously, who would want to do that?)

(3) eepic.sty, eepicemu.sty:
    The macros are in public domain.
    You may distribute or modify it in any ways you like.
    epic.sty:
    You may use this file in whatever way you wish. You are requested to 
    leave this notice intact, and report any bugs, enhancements, comments,
    suggestions, etc. to:
    ...

(4) TeX, MetaFont and the Computer Modern fonts 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.  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 willmake 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.
