COPYING CONDITIONS FOR TeX Live:
|
|
|
|
To the best of our knowledge, all software in the TeX Live distribution
|
|
is freely redistributable (libre, that is, not necessarily gratis),
|
|
within the Free Software Foundation's definition and the Debian Free
|
|
Software Guidelines. Where the two conflict, we generally follow the
|
|
FSF. If you find any non-free files included, please contact us
|
|
(references given at the end).
|
|
|
|
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
|
|
independent 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: https://ctan.org/tex-archive/help/Catalogue/ (or any
|
|
CTAN mirror). 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 TeX Collection DVD 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.
|
|
|
|
To state explicitly what is implied by the above: Because TeX Live is
|
|
free software, there is no warranty; not even for MERCHANTABILITY or
|
|
FITNESS FOR A PARTICULAR PURPOSE.
|
|
|
|
|
|
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 so:
|
|
|
|
- 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 file
|
|
README.<yourwork> 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> DVD, based on
|
|
TeX Live YYYY", where YYYY is the release year of TeX Live you are
|
|
using. 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. 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, as listed on the web page https://tug.org/usergroups.html.
|
|
|
|
b) Referencing the TeX Live home page: https://tug.org/texlive/
|
|
|
|
Such information 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 again 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/dev.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, be aware that
|
|
TeX Live is produced entirely by volunteers, and no dates can be
|
|
guaranteed.
|
|
|
|
|
|
LICENSING FOR NEW PACKAGES:
|
|
|
|
Finally, we have been 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 General
|
|
Public License, the modified BSD license, etc. (Please use an existing
|
|
license instead of making up your own.) Furthermore, all sources must
|
|
be available, including for documentation files. Please see
|
|
https://tug.org/texlive/pkgcontrib.html for more information, and other
|
|
considerations.
|
|
|
|
Thanks for your interest in TeX.
|
|
|
|
- Karl Berry, for the TeX Live project
