2 The LaTeX Project Public License
3 =-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-
5 LPPL Version 1.3 2003-12-01
7 Copyright 1999 2002-03 LaTeX3 Project
8 Everyone is allowed to distribute verbatim copies of this
9 license document, but modification of it is not allowed.
13 ========
15 The LaTeX Project Public License (LPPL) is the primary license under
16 which the the LaTeX kernel and the base LaTeX packages are distributed.
18 You may use this license for any work of which you hold the copyright
19 and which you wish to distribute. This license may be particularly
20 suitable if your work is TeX-related (such as a LaTeX package), but
21 you may use it with small modifications even if your work is unrelated
22 to TeX.
25 below, gives instructions, examples, and recommendations for authors
26 who are considering distributing their works under this license.
28 This license gives conditions under which a work may be distributed
29 and modified, as well as conditions under which modified versions of
30 that work may be distributed.
32 We, the LaTeX3 Project, believe that the conditions below give you
33 the freedom to make and distribute modified versions of your work
34 that conform with whatever technical specifications you wish while
35 maintaining the availability, integrity, and reliability of
36 that work. If you do not see how to achieve your goal while
37 meeting these conditions, then read the document `cfgguide.tex'
38 and `modguide.tex' in the base LaTeX distribution for suggestions.
42 ===========
44 In this license document the following terms are used:
46 `Work'
47 Any work being distributed under this License.
49 `Derived Work'
50 Any work that under any applicable law is derived from the Work.
52 `Modification'
53 Any procedure that produces a Derived Work under any applicable
54 law -- for example, the production of a file containing an
55 original file associated with the Work or a significant portion of
56 such a file, either verbatim or with modifications and/or
57 translated into another language.
59 `Modify'
60 To apply any procedure that produces a Derived Work under any
61 applicable law.
63 `Distribution'
64 Making copies of the Work available from one person to another, in
65 whole or in part. Distribution includes (but is not limited to)
66 making any electronic components of the Work accessible by
67 file transfer protocols such as FTP or HTTP or by shared file
68 systems such as Sun's Network File System (NFS).
70 `Compiled Work'
71 A version of the Work that has been processed into a form where it
72 is directly usable on a computer system. This processing may
73 include using installation facilities provided by the Work,
74 transformations of the Work, copying of components of the Work, or
75 other activities. Note that modification of any installation
76 facilities provided by the Work constitutes modification of the Work.
78 `Current Maintainer'
79 A person or persons nominated as such within the Work. If there is
80 no such explicit nomination then it is the `Copyright Holder' under
81 any applicable law.
83 `Base Interpreter'
84 A program or process that is normally needed for running or
85 interpreting a part or the whole of the Work.
86 A Base Interpreter may depend on external components but these
87 are not considered part of the Base Interpreter provided that each
88 external component clearly identifies itself whenever it is used
89 interactively. Unless explicitly specified when applying the
90 license to the Work, the only applicable Base Interpreter is a
91 "LaTeX-Format".
96 ===========================================
98 1. Activities other than distribution and/or modification of the Work
99 are not covered by this license; they are outside its scope. In
100 particular, the act of running the Work is not restricted and no
101 requirements are made concerning any offers of support for the Work.
103 2. You may distribute a complete, unmodified copy of the Work as you
104 received it. Distribution of only part of the Work is considered
105 modification of the Work, and no right to distribute such a Derived
106 Work may be assumed under the terms of this clause.
108 3. You may distribute a Compiled Work that has been generated from a
109 complete, unmodified copy of the Work as distributed under Clause 2
110 above, as long as that Compiled Work is distributed in such a way that
111 the recipients may install the Compiled Work on their system exactly
112 as it would have been installed if they generated a Compiled Work
113 directly from the Work.
115 4. If you are the Current Maintainer of the Work, you may, without
116 restriction, modify the Work, thus creating a Derived Work. You may
117 also distribute the Derived Work without restriction, including
118 Compiled Works generated from the Derived Work. Derived Works
119 distributed in this manner by the Current Maintainer are considered to
120 be updated versions of the Work.
122 5. If you are not the Current Maintainer of the Work, you may modify
123 your copy of the Work, thus creating a Derived Work based on the Work,
124 and compile this Derived Work, thus creating a Compiled Work based on
125 the Derived Work.
127 6. If you are not the Current Maintainer of the Work, you may
128 distribute a Derived Work provided the following conditions are met
129 for every component of the Work unless that component clearly states
130 in the copyright notice that it is exempt from that condition. Only
131 the Current Maintainer is allowed to add such statements of exemption
132 to a component of the Work.
134 a. If a component of this Derived Work can be a direct replacement
135 for a component of the Work when that component is used with the
136 Base Interpreter, then, wherever this component of the Work
137 identifies itself to the user when used interactively with that
138 Base Interpreter, the replacement component of this Derived Work
139 clearly and unambiguously identifies itself as a modified version
140 of this component to the user when used interactively with that
141 Base Interpreter.
143 b. Every component of the Derived Work contains prominent notices
144 detailing the nature of the changes to that component, or a
145 prominent reference to another file that is distributed as part
146 of the Derived Work and that contains a complete and accurate log
147 of the changes.
149 c. No information in the Derived Work implies that any persons,
150 including (but not limited to) the authors of the original version
151 of the Work, provide any support, including (but not limited to)
152 the reporting and handling of errors, to recipients of the
153 Derived Work unless those persons have stated explicitly that
154 they do provide such support for the Derived Work.
156 d. You distribute at least one of the following with the Derived Work:
158 1. A complete, unmodified copy of the Work;
159 if your distribution of a modified component is made by
160 offering access to copy the modified component from a
161 designated place, then offering equivalent access to copy
162 the Work from the same or some similar place meets this
163 condition, even though third parties are not compelled to
164 copy the Work along with the modified component;
166 2. Information that is sufficient to obtain a complete, unmodified
167 copy of the Work.
169 7. If you are not the Current Maintainer of the Work, you may
170 distribute a Compiled Work generated from a Derived Work, as long as
171 the Derived Work is distributed to all recipients of the Compiled
172 Work, and as long as the conditions of Clause 6, above, are met with
173 regard to the Derived Work.
175 8. The conditions above are not intended to prohibit, and hence do
176 not apply to, the modification, by any method, of any component so that it
177 becomes identical to an updated version of that component of the Work as
178 it is distributed by the Current Maintainer under Clause 4, above.
180 9. Distribution of the Work or any Derived Work in an alternative
181 format, where the Work or that Derived Work (in whole or in part) is
182 then produced by applying some process to that format, does not relax or
183 nullify any sections of this license as they pertain to the results of
184 applying that process.
186 10. a. A Derived Work may be distributed under a different license
187 provided that license itself honors the conditions listed in
188 Clause 6 above, in regard to the Work, though it does not have
189 to honor the rest of the conditions in this license.
191 b. If a Derived Work is distributed under this license, that
192 Derived Work must provide sufficient documentation as part of
193 itself to allow each recipient of that Derived Work to honor the
194 restrictions in Clause 6 above, concerning changes from the Work.
196 11. This license places no restrictions on works that are unrelated to
197 the Work, nor does this license place any restrictions on aggregating
198 such works with the Work by any means.
200 12. Nothing in this license is intended to, or may be used to, prevent
201 complete compliance by all parties with all applicable laws.
205 ===========
207 There is no warranty for the Work. Except when otherwise stated in
208 writing, the Copyright Holder provides the Work `as is', without
209 warranty of any kind, either expressed or implied, including, but not
210 limited to, the implied warranties of merchantability and fitness for
211 a particular purpose. The entire risk as to the quality and performance
212 of the Work is with you. Should the Work prove defective, you
213 assume the cost of all necessary servicing, repair, or correction.
215 In no event unless agreed to in writing will the Copyright Holder, or
216 any author named in the components of the Work, or any other party who
217 may distribute and/or modify the Work as permitted above, be liable to
218 you for damages, including any general, special, incidental or
219 consequential damages arising out of any use of the Work or out of
220 inability to use the Work (including, but not limited to, loss of
221 data, data being rendered inaccurate, or losses sustained by anyone as
222 a result of any failure of the Work to operate with any other
223 programs), even if the Copyright Holder or said author or said other
224 party has been advised of the possibility of such damages.
228 =======================
230 The Work has the status `author-maintained' if the Copyright Holder
231 explicitly and prominently states near the primary copyright notice in
232 the Work that the Work can only be maintained by the Copyright Holder
233 or simply that is `author-maintained'.
235 The Work has the status `maintained' if there is a Current Maintainer
236 who has indicated in the Work that they are willing to receive error
237 reports for the Work (for example, by supplying a valid e-mail
238 address). It is not required for the Current Maintainer to acknowledge
239 or act upon these error reports.
241 The Work changes from status `maintained' to `unmaintained' if there
242 is no Current Maintainer, or the person stated to be Current
243 Maintainer of the work cannot be reached through the indicated means
244 of communication for a period of six months, and there are no other
245 significant signs of active maintenance.
247 You can become the Current Maintainer of the Work by agreement with
248 any existing Current Maintainer to take over this role.
250 If the Work is unmaintained, you can become the Current Maintainer of
251 the Work through the following steps:
253 1. Make a reasonable attempt to trace the Current Maintainer (and
254 the Copyright Holder, if the two differ) through the means of
255 an Internet or similar search.
257 2. If this search is successful, then enquire whether the Work
258 is still maintained.
260 a. If it is being maintained, then ask the Current Maintainer
261 to update their communication data within one month.
263 b. If the search is unsuccessful or no action to resume active
264 maintenance is taken by the Current Maintainer, then announce
265 within the pertinent community your intention to take over
266 maintenance. (If the Work is a LaTeX work, this could be
267 done, for example, by posting to comp.text.tex.)
269 3a. If the Current Maintainer is reachable and agrees to pass
270 maintenance of the Work to you, then this takes effect
271 immediately upon announcement.
273 b. If the Current Maintainer is not reachable and the Copyright
274 Holder agrees that maintenance of the Work be passed to you,
275 then this takes effect immediately upon announcement.
277 4. If you make an `intention announcement' as described in 2b. above
278 and after three months your intention is challenged neither by
279 the Current Maintainer nor by the Copyright Holder nor by other
280 people, then you may arrange for the Work to be changed so as
281 to name you as the (new) Current Maintainer.
283 5. If the previously unreachable Current Maintainer becomes
284 reachable once more within three months of a change completed
285 under the terms of 3b) or 4), then that Current Maintainer must
286 become or remain the Current Maintainer upon request provided
287 they then update their communication data within one month.
289 A change in the Current Maintainer does not, of itself, alter the fact
290 that the Work is distributed under the LPPL license.
292 If you become the Current Maintainer of the Work, you should
293 immediately provide, within the Work, a prominent and unambiguous
294 statement of your status as Current Maintainer. You should also
295 announce your new status to the same pertinent community as
296 in 2b) above.
300 ======================================================
302 This section contains important instructions, examples, and
303 recommendations for authors who are considering distributing their
304 works under this license. These authors are addressed as `you' in
305 this section.
307 Choosing This License or Another License
308 ----------------------------------------
310 If for any part of your work you want or need to use *distribution*
311 conditions that differ significantly from those in this license, then
312 do not refer to this license anywhere in your work but, instead,
313 distribute your work under a different license. You may use the text
314 of this license as a model for your own license, but your license
315 should not refer to the LPPL or otherwise give the impression that
316 your work is distributed under the LPPL.
318 The document `modguide.tex' in the base LaTeX distribution explains
319 the motivation behind the conditions of this license. It explains,
320 for example, why distributing LaTeX under the GNU General Public
321 License (GPL) was considered inappropriate. Even if your work is
322 unrelated to LaTeX, the discussion in `modguide.tex' may still be
323 relevant, and authors intending to distribute their works under any
324 license are encouraged to read it.
326 A Recommendation on Modification Without Distribution
327 -----------------------------------------------------
329 It is wise never to modify a component of the Work, even for your own
330 personal use, without also meeting the above conditions for
331 distributing the modified component. While you might intend that such
332 modifications will never be distributed, often this will happen by
333 accident -- you may forget that you have modified that component; or
334 it may not occur to you when allowing others to access the modified
335 version that you are thus distributing it and violating the conditions
336 of this license in ways that could have legal implications and, worse,
337 cause problems for the community. It is therefore usually in your
338 best interest to keep your copy of the Work identical with the public
339 one. Many works provide ways to control the behavior of that work
340 without altering any of its licensed components.
342 How to Use This License
343 -----------------------
345 To use this license, place in each of the components of your work both
346 an explicit copyright notice including your name and the year the work
347 was authored and/or last substantially modified. Include also a
348 statement that the distribution and/or modification of that
349 component is constrained by the conditions in this license.
351 Here is an example of such a notice and statement:
353 %% pig.dtx
354 %% Copyright 2003 M. Y. Name
355 %
356 % This work may be distributed and/or modified under the
357 % conditions of the LaTeX Project Public License, either version 1.3
358 % of this license or (at your option) any later version.
359 % The latest version of this license is in
360 % http://www.latex-project.org/lppl.txt
361 % and version 1.3 or later is part of all distributions of LaTeX
362 % version 2003/12/01 or later.
363 %
364 % This work has the LPPL maintenance status "maintained".
365 %
366 % This Current Maintainer of this work is M. Y. Name.
367 %
368 % This work consists of the files pig.dtx and pig.ins
369 % and the derived file pig.sty.
371 Given such a notice and statement in a file, the conditions
372 given in this license document would apply, with the `Work' referring
373 to the three files `pig.dtx', `pig.ins', and `pig.sty' (the last being
374 generated from `pig.dtx' using `pig.ins'), the `Base Interpreter'
375 referring to any "LaTeX-Format", and both `Copyright Holder' and
376 `Current Maintainer' referring to the person `M. Y. Name'.
378 To prevent the Maintenance section of LPPL from allowing someone else
379 to become the Current Maintainer without your agreement, you could
380 change "maintained" above into "author-maintained".
383 Important Recommendations
384 -------------------------
386 Defining What Constitutes the Work
388 The LPPL requires that distributions of the Work contain all the
389 files of the Work. It is therefore important that you provide a
390 way for the licensee to determine which files constitute the Work.
391 This could, for example, be achieved by explicitly listing all the
392 files of the Work near the copyright notice of each file or by
393 using a line such as:
395 % This work consists of all files listed in manifest.txt.
397 in that place. In the absence of an unequivocal list it might be
398 impossible for the licensee to determine what is considered by you
399 to comprise the Work and, in such a case, the licensee would be
400 entitled to make reasonable conjectures as to which files comprise
401 the Work.
