COPYING CONDITIONS FOR TeX Live:

To the best of our knowledge, all software in this distribution is
freely redistributable (libre, that is, not necessarily gratis), within
the Free Software Foundation's definition and Debian Free Software
Guidelines.  If you find any non-free files included, please contact us
(references given below).

That said, TeX Live has neither a single copyright holder nor a single
license covering its entire contents, since it is a collection of many
disparate packages.  Therefore, you may copy, modify, and/or
redistribute software from TeX Live only if you comply with the
requirements placed thereon by the owners of the respective packages.

To most easily learn these requirements, we suggest checking the TeX
Catalogue at: http://www.ctan.org/tex-archive/help/Catalogue/ (or any
CTAN mirror).  The Catalogue is also included in TeX Live in
./texmf/doc/html/catalogue/, but the online version will have updates.
Of course the legal statements within the packages themselves are the
final authority.

In some cases, TeX Live is distributed with a snapshot of the CTAN
archive, which is entirely independent of and separable from TeX Live
itself.  (The "live" DVD in the TeX Collection is one example of this.)
Please be aware that the CTAN snapshot contains many files which are
*not* freely redistributable; see LICENSE.CTAN for more information.


GUIDELINES FOR REDISTRIBUTION:

In general, you may redistribute TeX Live, with or without modification,
for profit or not, according to the usual free software tenets.  Here
are some general guidelines for doing this:

- If you make any changes to the TeX Live distribution or any
package it contains, besides complying with any licensing requirements,
you must prominently mention such changes in your modified distribution
so that users do not take your work for ours, and know to contact you,
not us, in case of questions or problems.  A new top-level
README.<yourwork> file is a good place to describe the general situation.

- Especially (but not necessarily) if changes or additions are made, we
recommend a clearly different title, such as "<your work> demo CD",
based on TeX Live YYYY demo (with updates)", where YYYY is the year of
TeX Live you are publishing.  This credits both our work and yours.

- You absolutely may *not* place your own copyright on the entire
distribution, since it is not your work (as stated above, TeX Live is
not created by any single person or entity).  Statements such as "all
rights reserved" and "may not be reproduced" are especially
reprehensible, since they are antithetical to the free software
principles under which TeX Live is produced.

- You may use any cover or media label designs that you wish.  Such
packaging and marketing details are not covered by any TeX Live license.

- Finally, we make the following requests (not legal requirements):

a) Acknowledging that TeX Live is developed as a joint effort by all TeX
   user groups, and encouraging the user/reader to join their user group
   of choice.
   
   The web page http://www.tug.org/usergroups.html may be referenced as
   a list of TeX user groups.  We also appreciate your explicitly
   listing all the user groups as given on that page, space permitting.

b) Referencing the TeX Live home page: http://www.tug.org/tex-live/.

c) Crediting the editor of the original TeX Live: Sebastian Rahtz.

Such credits may be placed on the label of your media, your cover,
and/or in accompanying text (for instance, in the acknowledgements
section of a book).

Finally, although it is certainly not a requirement, we'd like to invite
any redistributors to make a donation to the project, whether cash or
in-kind, for example via https://www.tug.org/donate.html.  Thanks.


If you have any questions or comments, *please* contact us.  In general,
we appreciate being given the chance to review any TeX Live-related
material in advance of publication, simply to avoid mistakes.  It is
much better to correct text on a CD label or in a book before thousands
of copies are made!

We are also happy to keep anyone planning a publication informed as to
our deadlines and progress.  Just let us know.  However, you should be
aware that TeX Live is produced entirely by volunteers, and no dates can
be guaranteed.


LICENSING FOR NEW PACKAGES:

Finally, we are often asked what license to use for new work.  To be
considered for inclusion on TeX Live, a package must use a free software
license, such as the LaTeX Project Public License, the GNU Public
License, the X Window System license, the modified BSD license, etc., or
be put into the public domain.  Please see the url's below for more
discussion of this.

Thanks for your interest in TeX.

3. Reference to an (incomplete) list of licenses of individual parts

Individual parts of this distribution have their own copyright and
license.

3.1 Explanation of the format of the following information

Since most packages use standard licenses, we have separated the list
of license texts and the list of packages and individual files with
their licenses.  In section 3.3 we provide the license texts and their
abbreviations used in in the file list.  The file list itself is
generated automatically from the TeX Catalogue and can be found, for
each binary package, in /usr/share/doc/texlive-<name>/Licenses.

The information in the TeX Catalogue is checked by the Debian TeX
maintainers and the CTAN maintainers.  If you find any contradiction
in the listing with the reality please inform us.

In the case of gpl and lppl, the string without a number means that
the license statement contains a "or any later version" statement.  In
the list in Licenses, each package has a header line like this:

% ccfonts: lppl (verification data:1.1:1.1:2006-03-14:frank:readme)

indicating that the package ccfonts is under LPPL, exists in version
1.1, the license has been checked in version 1.1 on 2006-03-14 by
"frank" (the username among the Catalogue developers, actually Frank
Kster), and the license information is in a file "readme".  After
that follows the list of files, 

 tex/latex/ccfonts/t1ccr.fd
 tex/latex/ccfonts/ccfonts.sty
 tex/latex/ccfonts/ts1ccr.fd
 doc/latex/ccfonts/*

where the * indicates that all ordinary files in that directory belong
to that package (but not necessarily subdirectories and files
therein).

3.2 TODO: Packages with licensing problems

[ this is copied over from teTeX, and some problems might already be
solved ]

3.2.1 Serious problems

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

- adrconv: No license at all for the documentation

- antp: PD according to catalogue, no statement in the files, no
  sources; contacted upstream

- bbm: no license statement at all, bug filed

- cite:  chapterbib.sty is missing a license statement in the header

- Problematic files by Donald Arseneau:

  * chapterbib.sty: no license information
  * tabls.sty: no license information
  * import.sty: "this software is free of any restrictions"
  * relsize.sty: "public domain", nothing else
  * shapepar.sty: noncommercial
  * version.sty: no license information, not only by D.A.
  * selectp.sty: no license information
  *./source/latex/shapepar/README.shapepar
   ./source/latex/shapepar/shapepar.sty
   ./source/latex/shapepar/shapepar.ltx
   ./source/latex/hyphenat/hyphenat.dtx: no license information


- citesort.sty: no license statement

- index.doc: no license statement - probably unused

- dinbrief: lppl 1.1+, but with additional restrictions which are non-free

- eepic: The style files are public domain, but all the documentation
  has no license at all.

- extsizes: extsizes.sty, extarticle.cls and extreport.cls, and the
  size*.clo files have a correct LPPL notice, the others have none.
  The author seems to be active on Wikipedia, tried to contact him

- beamericon*: no license statement. beamerexample-seminar: just like
  seminar, which has not been investigated yet.  Filed bug against beamer.

- one file in the psnfss directory with unclear license:

    tex/latex/psnfss/8r.sty

3.2.2 Normal :-) problems

- 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.

      contacted upstream

- antt: gust font license, unclear which files % contacted upstream


3.3 Individual license texts

The actual text of the licenses can either be found in
/usr/share/common-licenses (for artistic,bsd,gpl) or in "3.2 Text of
the licenses" below.  For BSD-like licenses that just exchange the
name of the copyright holder, we do not list the license text.

A. gpl (GNU General Public License)

The full text of the GPL is given in /usr/share/common-licenses/GPL.

B. lppl (LaTeX Project Public License)

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


C. 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 and
distribute it".

E. Non-standard licenses, by package name:

(1) 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:
    ...

(2) The Computer Modern fonts by Donald E. Knuth 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.tug.org/TUGboat/Articles/tb11-4/tb30knut.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 TEX or 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 copyright page of Volume $of "Computers and Typesetting"
   by Donald E. Knuth, which present the commented code for the Computer Modern fonts:

   ,----
   | The quotations on pages 7 and 351 have been excerpted [...].
   | 
   | METAFONT is a trademark of th Addison Wesley Publishing Company.
   | 
   | TeX is a trademark of the American Mathematical Society.
   | 
   | The programs for computer Modern are in the public domain, and readers
   | may freely generate and hand-tune their own fonts using the algorithms
   | of this book.  However, use of the names is restricted:  Any fonts
   | whose names cmr10 or cmbx12 or ... are identical to the standard font
   | names of this book should be fully compatible with the fonts defined
   | here; i.e., fonts with the same names are supposed to have precisely
   | the same character coding schemes and precisely the same font metric
   | files.
