Hi guys, Last year I posted an analysis in two parts[1][2] of the then-draft version of the LaTeX Project Public License (LPPL). In December, Frank Küster asked what the status of the LPPL was[3], and I told him I didn't know[4]. Well, that same month, the LaTeX Project folks finalized the license and and announced it[5][6]. They also announced that they're seeking Open Source certification of the license[7]. Oddly, the version of the LPPL shipped in tetex-base[8] is still version 1.2, and a review of the tetex package changelog shows no new upstream release since 2.0.2.[9]. I am therefore not sure Debian is shipping anything under the new license yet. Nevertheless, I thought I would present a diff and word diff of the last draft submitted to us, and the final version of LPPL 1.3. It looks like Mr. Mittelbach and the rest of the LaTeX3 Project took almost all of advice. I feel good about that. :) [1] Message-ID: <20030628082558.GP19841@deadbeast.net> [2] Message-ID: <20030905092430.GB13851@deadbeast.net> [3] Message-ID: <87llpidqdq.fsf@alhambra.bioz.unibas.ch> [4] Message-ID: <20031213220933.GE3310@deadbeast.net> [5] http://www.latex-project.org/lppl/ [6] http://www.latex-project.org/ltnews/ltnews15.pdf [7] http://www.latex-project.org/ltnews/ltnews16.pdf [8] file:///usr/share/doc/tetex-base/lppl.txt.gz [9] file:///usr/share/doc/tetex-base/changelog.Debian.gz -- G.

interpreting a part or the whole of [-The-] {+the+} Work.
A Base Interpreter may depend on external components but these
are not considered part of the Base Interpreter provided that {+each+}
external component clearly identifies itself whenever it is used
interactively. Unless explicitly specified when applying the
license to [-The Work-] {+the Work,+} the only applicable Base Interpreter is a
"LaTeX-Format".
CONDITIONS ON DISTRIBUTION AND MODIFICATION
===========================================
1. Activities other than distribution and/or modification of [-The-] {+the+} Work
are not covered by this license; they are outside its scope. In
particular, the act of running [-The-] {+the+} Work is not restricted and no
requirements are made concerning any offers of support for [-The-] {+the+} Work.
2. You may distribute a complete, unmodified copy of [-The-] {+the+} Work as you
received it. Distribution of only part of [-The-] {+the+} Work is considered
modification of [-The-] {+the+} Work, and no right to distribute such a Derived
Work may be assumed under the terms of this clause.
3. You may distribute a Compiled Work that has been generated from a
complete, unmodified copy of [-The-] {+the+} Work as distributed under Clause 2
above, as long as that Compiled Work is distributed in such a way that
the recipients may install the Compiled Work on their system exactly
as it would have been installed if they generated a Compiled Work
directly from [-The-] {+the+} Work.
4. If you are the Current Maintainer of [-The-] {+the+} Work, you [-may-] {+may, without
restriction,+} modify [-The-] {+the+} Work, {+thus+} creating a Derived [-Work, without restriction.-] {+Work.+} You may
also distribute the Derived Work without restriction, including
Compiled Works generated from the Derived Work. Derived Works
distributed in this manner by the Current Maintainer are considered to
be updated versions of [-The-] {+the+} Work.
5. If you are not the Current Maintainer of [-The-] {+the+} Work, you may modify
your copy of [-The-] {+the+} Work, thus creating a Derived Work based on [-The-] {+the+} Work,
and compile this Derived Work, thus creating a Compiled Work based on
the Derived Work.
6. If you are not the Current Maintainer of [-The-] {+the+} Work, you may
distribute a Derived Work provided the following conditions are met
for every component of the Work unless that component [-is-] clearly
[-stated to be-] {+states
in the copyright notice that it is+} exempt from that condition. {+Only
the Current Maintainer is allowed to add such statements of exemption
to a component of the Work.+}
a. If a component of this Derived Work can be a direct replacement
for a component of [-The-] {+the+} Work when that component is used with the
Base Interpreter, then, wherever this component of [-The-] {+the+} Work
identifies itself to the user when used interactively with that
Base Interpreter, the replacement component of this Derived Work
clearly and unambiguously identifies itself as a modified version
of this component to the user when used interactively with that
Base Interpreter.
b. Every [-file-] {+component+} of the Derived Work contains prominent notices
detailing the nature of the [-changes,-] {+changes to that component,+} or a
prominent reference to another file that is distributed as part
of the Derived Work and that contains a complete and accurate log
of the changes.
c. No information in the Derived Work implies that {+any persons,
including (but not limited to)+} the authors of the original version
of [-The Work-] {+the Work,+} provide any support, including (but not limited to)
the reporting and handling of errors, to recipients of the
Derived Work unless those [-authors-] {+persons+} have stated explicitly that
they do provide such support for the Derived Work.
d. You distribute {+at least+} one of the following with the Derived Work:
1. A complete, unmodified copy of [-The-] {+the+} Work;
if your distribution of a modified [-file-] {+component+} is made by
offering access to copy the modified [-file-] {+component+} from a
designated place, then offering equivalent access to copy [-The-]
{+the+} Work from the same {+or some similar+} place meets this
condition, even though third parties are not compelled to
copy [-The-] {+the+} Work along with the modified [-file;-] {+component;+}
2. Information that is sufficient to obtain a complete, unmodified
copy of [-The-] {+the+} Work.
7. If you are not the Current Maintainer of [-The-] {+the+} Work, you may
distribute a Compiled Work generated from a Derived Work, as long as
the Derived Work is distributed to all recipients of the Compiled
Work, and as long as the conditions of Clause 6, above, are met with [-regards-]
{+regard+} to the Derived Work.
8. The conditions above are not intended to prohibit, and hence do
not apply to, the modification, by any method, of [-a file-] {+any component+} so that it
becomes identical to an updated version of that [-file-] {+component+} of [-The-] {+the+} Work as
it is distributed by the Current Maintainer under Clause 4, above.
9. Distribution of [-The-] {+the+} Work or any Derived Work in [-a packed-] {+an alternative+}
format, where [-The-] {+the+} Work or that Derived Work (in whole or in part) is [-generated-]
{+then produced+} by [-running-] {+applying+} some [-other program on-] {+process to+} that [-packed-] format, does not relax or
nullify any sections of this license as they pertain to the [-files-] {+results of
applying+} that
[-are unpacked from the packed format.-] {+process.+}
10. a. A Derived Work may be distributed under a different license
provided that license itself honors the conditions listed in
Clause 6 above, in regard to [-The-] {+the+} Work, though it does not have
to honor the rest of the conditions in this license.
b. If a Derived Work is distributed under this license, that
Derived Work must provide sufficient documentation as part of
[-the-]
itself to allow [-all recipients-] {+each recipient+} of that Derived Work to honor the
restrictions in Clause 6 above, concerning changes from [-The-] {+the+} Work.
11. This license places no restrictions on works that are unrelated to
[-The-]
{+the+} Work, nor does this license place any restrictions on aggregating
such works with [-The-] {+the+} Work by any means.
12. Nothing in this license is intended to, or may be used to, prevent
complete compliance by all parties with all applicable laws.
NO WARRANTY
===========
There is no warranty for [-The-] {+the+} Work. Except when otherwise stated in
writing, the Copyright Holder provides [-The-] {+the+} Work `as is', without
warranty of any kind, either expressed or implied, including, but not
limited to, the implied warranties of merchantability and fitness for
a particular purpose. The entire risk as to the quality and performance
of [-The-] {+the+} Work is with you. Should [-The-] {+the+} Work prove defective, you
assume the cost of all necessary servicing, repair, or correction.
In no event unless agreed to in writing will the Copyright Holder, or
any author named in the [-files-] {+components+} of [-The-] {+the+} Work, or any other party who
may distribute and/or modify [-The-] {+the+} Work as permitted above, be liable to
you for damages, including any general, special, incidental or
consequential damages arising out of any use of [-The-] {+the+} Work or out of
inability to use [-The-] {+the+} Work (including, but not limited to, loss of
data, data being rendered inaccurate, or losses sustained by anyone as
a result of any failure of [-The-] {+the+} Work to operate with any other
programs), even if the Copyright Holder or said author or said other
party has been advised of the possibility of such damages.
MAINTENANCE OF THE WORK
=======================
The Work has the status `author-maintained' if the Copyright Holder
explicitly {+and prominently+} states {+near the primary copyright notice in
the Work+} that [-The-] {+the+} Work can only be maintained by the Copyright [-Holder.-] {+Holder
or simply that is `author-maintained'.+}
The Work has the status `maintained' if there is a Current Maintainer
who has indicated in [-The-] {+the+} Work that they are willing to receive error
reports for [-The-] {+the+} Work (for example, by supplying a valid e-mail
address). It is not required for the Current Maintainer to acknowledge
or act upon these error reports.
The Work changes from status `maintained' to `unmaintained' if there
is no Current Maintainer, or the person stated to be Current
Maintainer of the work cannot be reached through the indicated means
of communication for a period of six months, and there are no other
{+significant+} signs of active maintenance.
You can become the Current Maintainer of [-The-] {+the+} Work by agreement with
any existing Current Maintainer to take over this role.
If [-The-] {+the+} Work is unmaintained, you can become the Current Maintainer of
[-The-]
{+the+} Work through the following steps:
1. Make a reasonable attempt to trace the Current Maintainer (and
{+the+} Copyright Holder, if the two differ) through the means of
{+an+} Internet [-Search, etc.-] {+or similar search.+}
2. If this search is successful, [-inquire-] {+then enquire+} whether [-The-] {+the+} Work
is still maintained.
a. If it is being maintained, {+then+} ask the Current Maintainer
to update
[-the-] {+their+} communication [-data.-] {+data within one month.+}
b. [-Otherwise,-] {+If the search is unsuccessful or no action to resume active
maintenance is taken by the Current Maintainer, then+} announce
{+within the pertinent community+} your intention to take over [-maintenance
within the pertinent community.-]
{+maintenance.+} (If [-The-] {+the+} Work is a LaTeX work, this could be
done, for example, by posting to comp.text.tex.)
3a. If the Current Maintainer is reachable and agrees to pass
maintenance of [-The-] {+the+} Work to you, then this takes effect
immediately upon announcement.
b. If the Current Maintainer is not reachable and [-if-] {+the Copyright
Holder agrees that maintenance of the Work be passed to you,
then this takes effect immediately upon announcement.
4. If you make an `intention announcement' as described in 2b. above
and+} after three months your intention is challenged neither by
the Current Maintainer nor by {+the Copyright Holder nor by+} other
people, then you may arrange for [-a change
of The-] {+the+} Work to {+be changed so as
to+} name you as the (new) Current Maintainer.
[-4.-]
{+5.+} If the previously unreachable Current Maintainer [-returns-] {+becomes
reachable once more+} within
[-six months,-] {+three months of a change completed
under the terms of 3b) or 4), then+} that Current Maintainer must
become or remain the Current Maintainer upon [-request.-] {+request provided
they then update their communication data within one month.+}
A change in the Current Maintainer does [-not-] {+not, of itself,+} alter the fact
that [-The-] {+the+} Work is distributed under the LPPL license.
If you become the Current Maintainer of [-The Work-] {+the Work,+} you should [-ensure
that this is clearly stated in The Work by changing-]
{+immediately provide, within+} the [-nomination or
by or adding one.-] {+Work, a prominent and unambiguous
statement of your status as Current Maintainer. You should also
announce your new status to the same pertinent community as
in 2b) above.+}
WHETHER AND HOW TO DISTRIBUTE WORKS UNDER THIS LICENSE
======================================================
This section contains important instructions, examples, and
recommendations for authors who are considering distributing their
works under this license. These authors are addressed as `you' in
this section.
Choosing This License or Another License
----------------------------------------
If for any part of your work you want or need to use *distribution*
conditions that differ significantly from those in this license, then
do not refer to this license anywhere in your work [-but instead-] {+but, instead,+}
distribute your work under a different license. You may use the text
of this license as a model for your own license, but your license
should not refer to the LPPL or otherwise give the impression that
your work is distributed under the LPPL.
The document `modguide.tex' in the base LaTeX distribution explains
the motivation behind the conditions of this license. It explains,
for example, why distributing LaTeX under the GNU General Public
License (GPL) was considered inappropriate. Even if your work is
unrelated to LaTeX, the discussion in `modguide.tex' may still be
relevant, and authors intending to distribute their works under any
license are encouraged to read it.
A Recommendation on Modification Without Distribution
-----------------------------------------------------
It is wise never to modify a [-file-] {+component+} of [-The-] {+the+} Work, even for your own
personal use, without also meeting the above conditions for
distributing the modified [-file.-] {+component.+} While you might intend that such
[-modified files-]
{+modifications+} will never be distributed, often this will happen by
accident -- you may forget that you have modified [-the file;-] {+that component;+} or
it may not occur to you when allowing others to access the modified [-file-]
{+version+} that you are thus distributing it and violating the conditions
of this
[-license.-] {+license in ways that could have legal implications and, worse,
cause problems for the community.+} It is {+therefore+} usually in your
best interest to keep your copy of [-The-] {+the+} Work identical with the public
one. Many [-Works-] {+works+} provide ways to control the behavior of that [-Work-] {+work+}
without altering {+any of+} its licensed [-files.-] {+components.+}
How to Use This License
-----------------------
To use this license, place in each of the [-files-] {+components+} of your work both
an explicit copyright notice including your name and the year [-and-] {+the work
was authored and/or last substantially modified. Include+} also a
statement that the distribution and/or modification of [-the file-] {+that
component+} is constrained by the conditions in this license.
Here is an example of such a notice and statement:
%% pig.dtx
%% Copyright 2003 M. Y. Name
%
% This work may be distributed and/or modified under the
% conditions of the LaTeX Project Public License, either version 1.3
% of this license or (at your option) any later version.
% The latest version of this license is in
% http://www.latex-project.org/lppl.txt
% and version 1.3 or later is part of all distributions of LaTeX
% version [-2003/06/01-] {+2003/12/01+} or later.
%
% This work has the LPPL maintenance status "maintained".
%
% This Current Maintainer of this work is M. Y. [-Name-] {+Name.+}
%
% This work consists of the files pig.dtx and pig.ins
% and the derived file pig.sty.
Given such a notice and statement in a file, the conditions
given in this license document would apply, with [-`The Work'-] {+the `Work'+} referring
to the three files `pig.dtx', `pig.ins', and `pig.sty' [-(generated-] {+(the last being
generated+} from `pig.dtx' using `pig.ins'), the `Base Interpreter'
referring to any
[-`LaTeX-Format',-] {+"LaTeX-Format",+} and both `Copyright Holder' and
`Current Maintainer' referring to the person `M. Y. Name'.
To prevent the Maintenance section of LPPL {+from+} allowing someone else
to become the Current Maintainer without your agreement, you could
change "maintained" above into "author-maintained".
Important Recommendations
-------------------------
Defining What Constitutes [-The-] {+the+} Work
The LPPL requires that distributions of [-The-] {+the+} Work contain all the
files of [-The-] {+the+} Work. It is therefore important that you provide a
way for the licensee to determine which files constitute [-The-] {+the+} Work.
This could, for example, be achieved by explicitly listing all the
files of [-The-] {+the+} Work near the copyright notice of each file or by
using a line [-like-] {+such as:+}
% This work consists of all files listed in manifest.txt.
in that place. In the absence of an unequivocal list it might be
impossible for the licensee to determine what is considered by you
to comprise [-The-] {+the Work and, in such a case, the licensee would be
entitled to make reasonable conjectures as to which files comprise
the+} Work.
