This license may be + particularly suitable if your work is \TeX-related (such as a + \LaTeX\ package), but it is written in such a way that you can use + it even if your work is unrelated to \TeX. + + The section `WHETHER AND HOW TO DISTRIBUTE WORKS UNDER THIS + LICENSE', below, gives instructions, examples, and recommendations + for authors who are considering distributing their works under this + license. + + This license gives conditions under which a work may be distributed + and modified, as well as conditions under which modified versions of + that work may be distributed. + + We, the \LaTeX3 Project, believe that the conditions below give you + the freedom to make and distribute modified versions of your work + that conform with whatever technical specifications you wish while + maintaining the availability, integrity, and reliability of that + work. If you do not see how to achieve your goal while meeting + these conditions, then read the document \LPPLdocfile{cfgguide} and + \LPPLdocfile{modguide} in the base \LaTeX\ distribution for suggestions. + + + \LPPLsubsection{Definitions} + \label{LPPL:Definitions} + + In this license document the following terms are used: + + \begin{description} + \item[Work] Any work being distributed under this License. + + \item[Derived Work] Any work that under any applicable law is + derived from the Work. + + \item[Modification] Any procedure that produces a Derived Work under + any applicable law -- for example, the production of a file + containing an original file associated with the Work or a + significant portion of such a file, either verbatim or with + modifications and/or translated into another language. + + \item[Modify] To apply any procedure that produces a Derived Work + under any applicable law. + + \item[Distribution] Making copies of the Work available from one + person to another, in whole or in part. Distribution includes + (but is not limited to) making any electronic components of the + Work accessible by file transfer protocols such as \textsc{ftp} or + \textsc{http} or by shared file systems such as Sun's Network File + System (\textsc{nfs}). + + \item[Compiled Work] A version of the Work that has been processed + into a form where it is directly usable on a computer system. + This processing may include using installation facilities provided + by the Work, transformations of the Work, copying of components of + the Work, or other activities. Note that modification of any + installation facilities provided by the Work constitutes + modification of the Work. + + \item[Current Maintainer] A person or persons nominated as such + within the Work. If there is no such explicit nomination then it + is the `Copyright Holder' under any applicable law. + + \item[Base Interpreter] A program or process that is normally needed + for running or interpreting a part or the whole of 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 only applicable Base Interpreter is a + `\LaTeX-Format' or in the case of files belonging to the + `\LaTeX-format' a program implementing the `\TeX{} language'. + \end{description} + + \LPPLsubsection{Conditions on Distribution and Modification} + \label{LPPL:Conditions} + + \begin{enumerate} + \item Activities other than distribution and/or modification of the + Work are not covered by this license; they are outside its scope. + In particular, the act of running the Work is not restricted and + no requirements are made concerning any offers of support for the + Work. + + \item\label{LPPL:item:distribute} You may distribute a complete, unmodified + copy of the Work as you received it. Distribution of only part of + the Work is considered modification of the Work, and no right to + distribute such a Derived Work may be assumed under the terms of + this clause. + + \item You may distribute a Compiled Work that has been generated + from a complete, unmodified copy of the Work as distributed under + Clause~\ref{LPPL:item:distribute} 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 + Work. + + \item\label{LPPL:item:currmaint} If you are the Current Maintainer of the + Work, you may, without restriction, modify the Work, thus creating + a Derived 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 Work. + + \item If you are not the Current Maintainer of the Work, you may + modify your copy of the Work, thus creating a Derived Work based + on the Work, and compile this Derived Work, thus creating a + Compiled Work based on the Derived Work. + + \item\label{LPPL:item:conditions} If you are not the Current Maintainer + of the + Work, you may distribute a Derived Work provided the following + conditions are met for every component of the Work unless that + component clearly 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. + \begin{enumerate} + \item If a component of this Derived Work can be a direct + replacement for a component of the Work when that component is + used with the Base Interpreter, then, wherever this component of + 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. + + \item\label{LPPL:item:changelog} Every component of the Derived Work + contains prominent + notices detailing the nature of the 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. + + \item No information in the Derived Work implies that any persons, + including (but not limited to) the authors of the original + version of the Work, provide any support, including (but not + limited to) the reporting and handling of errors, to recipients + of the Derived Work unless those persons have stated explicitly + that they do provide such support for the Derived Work. + + \item\label{LPPL:item:unmodifiedcopy} You distribute at least one of + the following with the Derived Work: + \begin{enumerate} + \item A complete, unmodified copy of the Work; if your + distribution of a modified component is made by offering + access to copy the modified component from a designated place, + then offering equivalent access to copy the Work from the same + or some similar place meets this condition, even though third + parties are not compelled to copy the Work along with the + modified component; + + \item Information that is sufficient to obtain a complete, + unmodified copy of the Work. + \end{enumerate} + \end{enumerate} + \item If you are not the Current Maintainer of 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~\ref{LPPL:item:conditions}, above, are met with regard to the + Derived Work. + + \item The conditions above are not intended to prohibit, and hence + do not apply to, the modification, by any method, of any component + so that it becomes identical to an updated version of that + component of the Work as it is distributed by the Current + Maintainer under Clause~\ref{LPPL:item:currmaint}, above. + + \item Distribution of the Work or any Derived Work in an alternative + format, where the Work or that Derived Work (in whole or in part) + is then produced by applying some process to that format, does not + relax or nullify any sections of this license as they pertain to + the results of applying that process. + + \item + \begin{enumerate} + \item A Derived Work may be distributed under a different license + provided that license itself honors the conditions listed in + Clause~\ref{LPPL:item:conditions} above, in regard to the Work, though it + does not have to honor the rest of the conditions in this + license. + + \item If a Derived Work is distributed under a different license, + that Derived Work must provide sufficient documentation as part + of itself to allow each recipient of that Derived Work to honor + the restrictions in Clause~\ref{LPPL:item:conditions} above, concerning + changes from the Work. + \end{enumerate} + \item This license places no restrictions on works that are + unrelated to the Work, nor does this license place any + restrictions on aggregating such works with the Work by any means. + + \item Nothing in this license is intended to, or may be used to, + prevent complete compliance by all parties with all applicable + laws. + \end{enumerate} + + \LPPLsubsection{No Warranty} + \label{LPPL:Warranty} + + There is no warranty for the Work. Except when otherwise stated in + writing, the Copyright Holder provides 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 Work is with you. Should the Work prove + defective, you assume the cost of all necessary servicing, repair, + or correction. + + In no event unless required by applicable law or agreed to in + writing will The Copyright Holder, or any author named in the + components of the Work, or any other party who may distribute and/or + modify 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 Work or out of inability to use 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 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. + + \LPPLsubsection{Maintenance of The Work} + \label{LPPL:Maintenance} + + 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 Work can only be maintained by the Copyright + Holder or simply that it is `author-maintained'. + + The Work has the status `maintained' if there is a Current + Maintainer who has indicated in the Work that they are willing to + receive error reports for 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 Work by agreement with + any existing Current Maintainer to take over this role. + + If the Work is unmaintained, you can become the Current Maintainer + of the Work through the following steps: + \begin{enumerate} + \item Make a reasonable attempt to trace the Current Maintainer (and + the Copyright Holder, if the two differ) through the means of an + Internet or similar search. + \item If this search is successful, then enquire whether the Work is + still maintained. + \begin{enumerate} + \item If it is being maintained, then ask the Current Maintainer + to update their communication data within one month. + + \item\label{LPPL:item:intention} 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. (If the Work is a \LaTeX{} + work, this could be done, for example, by posting to + \texttt{comp.text.tex}.) + \end{enumerate} + \item {} + \begin{enumerate} + \item If the Current Maintainer is reachable and agrees to pass + maintenance of the Work to you, then this takes effect + immediately upon announcement. + + \item\label{LPPL:item:announce} If the Current Maintainer is not + reachable and the Copyright Holder agrees that maintenance of + the Work be passed to you, then this takes effect immediately + upon announcement. + \end{enumerate} + \item\label{LPPL:item:change} If you make an `intention + announcement' as described in~\ref{LPPL:item:intention} 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 the Work to be changed so as to + name you as the (new) Current Maintainer. + + \item If the previously unreachable Current Maintainer becomes + reachable once more within three months of a change completed + under the terms of~\ref{LPPL:item:announce} + or~\ref{LPPL:item:change}, then that Current Maintainer must + become or remain the Current Maintainer upon request provided they + then update their communication data within one month. + \end{enumerate} + A change in the Current Maintainer does not, of itself, alter the + fact that the Work is distributed under the \LPPL\ license. + + If you become the Current Maintainer of the Work, you should + immediately provide, within the 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~\ref{LPPL:item:intention} above. + + \LPPLsubsection{Whether and How to Distribute Works under This License} + \label{LPPL:Distribute} + + 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. + + \LPPLsubsubsection{Choosing This License or Another License} + \label{LPPL:Choosing} + + If for any part of your work you want or need to use + \emph{distribution} conditions that differ significantly from those + in this license, then do not refer to this license anywhere in your + work 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 \LPPLdocfile{modguide} in the base \LaTeX\ distribution + explains the motivation behind the conditions of this license. It + explains, for example, why distributing \LaTeX\ under the + \textsc{gnu} General Public License (\textsc{gpl}) was considered + inappropriate. Even if your work is unrelated to \LaTeX, the + discussion in \LPPLdocfile{modguide} may still be relevant, and authors + intending to distribute their works under any license are encouraged + to read it. + + \LPPLsubsubsection{A Recommendation on Modification Without Distribution} + \label{LPPL:WithoutDistribution} + + It is wise never to modify a component of the Work, even for your + own personal use, without also meeting the above conditions for + distributing the modified component. While you might intend that + such modifications will never be distributed, often this will happen + by accident -- you may forget that you have modified that component; + or it may not occur to you when allowing others to access the + modified version that you are thus distributing it and violating the + conditions of this 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 + Work identical with the public one. Many works provide ways to + control the behavior of that work without altering any of its + licensed components. + + \LPPLsubsubsection{How to Use This License} + \label{LPPL:HowTo} + + To use this license, place in each of the components of your work + both an explicit copyright notice including your name and the year + the work was authored and/or last substantially modified. Include + also a statement that the distribution and/or modification of that + component is constrained by the conditions in this license. + + Here is an example of such a notice and statement: +\begin{verbatim} + %% pig.dtx + %% Copyright 2005 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 + % https://www.latex-project.org/lppl.txt + % and version 1.3 or later is part of all distributions of LaTeX + % version 2005/12/01 or later. + % + % This work has the LPPL maintenance status `maintained'. + % + % The Current Maintainer of this work is M. Y. Name. + % + % This work consists of the files pig.dtx and pig.ins + % and the derived file pig.sty. +\end{verbatim} + + Given such a notice and statement in a file, the conditions given in + this license document would apply, with the `Work' referring to the + three files `\LPPLfile{pig.dtx}', `\LPPLfile{pig.ins}', and + `\LPPLfile{pig.sty}' (the last being generated from + `\LPPLfile{pig.dtx}' using `\LPPLfile{pig.ins}'), the `Base + Interpreter' referring to any `\LaTeX-Format', and both `Copyright + Holder' and `Current Maintainer' referring to the person `M. Y. + Name'. + + If you do not want the Maintenance section of \LPPL\ to apply to + your Work, change `maintained' above into `author-maintained'. + However, we recommend that you use `maintained' as the Maintenance + section was added in order to ensure that your Work remains useful + to the community even when you can no longer maintain and support it + yourself. + + \LPPLsubsubsection{Derived Works That Are Not Replacements} + \label{LPPL:NotReplacements} + + Several clauses of the \LPPL\ specify means to provide reliability + and stability for the user community. They therefore concern + themselves with the case that a Derived Work is intended to be used + as a (compatible or incompatible) replacement of the original + Work. If this is not the case (e.g., if a few lines of code are + reused for a completely different task), then clauses + \ref{LPPL:item:changelog} and \ref{LPPL:item:unmodifiedcopy} + shall not apply. + + \LPPLsubsubsection{Important Recommendations} + \label{LPPL:Recommendations} + + \LPPLparagraph{Defining What Constitutes the Work} + + The \LPPL\ requires that distributions of the Work contain all the + files of the Work. It is therefore important that you provide a way + for the licensee to determine which files constitute the Work. This + could, for example, be achieved by explicitly listing all the files + of the Work near the copyright notice of each file or by using a + line such as: +\begin{verbatim} + % This work consists of all files listed in manifest.txt. +\end{verbatim} + 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 Work and, in such a case, the licensee would be + entitled to make reasonable conjectures as to which files comprise + the Work. + +\end{LPPLicense} +\endinput |
