5 NOTES ON COPYRIGHTS AND LICENSES
6
7 Some terminology:
8
9 A "copyright notice" consists of one or a few lines of this format:
10 "Copyright (C) 2006, 2007 Free Software Foundation, Inc."
11
12 A "license notice" is a statement of permissions, and is usually much
13 longer, eg the text "GNU Emacs is free software...".
14
15
16 Summary for the impatient:
17
18 1. Don't add code to Emacs written by someone other than yourself
19 without thinking about the legal aspect. Even if the changes are
20 trivial, consider if they combine with previous changes by the same
21 author to make a non-trivial total. If so, make sure they have an
22 assignment. If adding a whole file adjust the copyright statements in
23 the file.
24
25 2. When installing code written by someone else, the ChangeLog entry
26 should be in the name of the author of the code, not the person who
27 installs it. I think it is helpful to put the author (if not yourself)
28 in the commit log as well (you can also use bzr commit's "--author"
29 option); and to not install any of your own changes in the same commit.
30
31 3. With images, add the legal info to a README file in the directory
32 containing the image.
33
34 4. If you add a lot of text to a previously trivial file that had no
35 legal notices, consider if you should add a copyright statement.
36
37 5. Please don't just add an FSF copyright without checking that is the
38 right thing to do.
39
40
41 Every non-trivial file distributed through the Emacs repository should be
42 self-explanatory in terms of copyright and license. This includes
43 files that are not distributed in Emacs releases (for example, the
44 admin/ directory), because the whole Emacs repository is publicly
45 available.
46
47 The definition of triviality is a little vague, but a rule of thumb is
48 that any file with less than 15 lines of actual content is trivial. If
49 a file is auto-generated (eg ldefs-boot.el) from another one in the
50 repository, then it does not really matter about adding a copyright
51 statement to the generated file.
52
53 Legal advice says that we could, if we wished, put a license notice
54 even in trivial files, because copyright law in general looks at the
55 overall work as a whole. It is not _necessary_ to do so, and rms
56 prefers that we do not. This means one needs to take care that trivial
57 files do not grow and become non-trivial without having a license
58 added. NB consequently, if you add a lot of text to a small file,
59 consider whether your changes have made the file worthy of a copyright
60 notice, and if so, please add one.
61
62 It can be helpful to put a reminder comment at the start of a trivial
63 file, eg: "add a license notice if this grows to > 10 lines of code".
64
65 The years in the copyright notice should be updated every year (see
66 file "years" in this directory). The PDF versions of refcards etc
67 should display copyright notices (an exception to the rule about
68 "generated" files), but these can just display the latest year. The
69 full list of years should be kept in comments in the source file. If
70 these are distributed in the repository, check in a regenerated
71 version when the tex files are updated.
72
73 Copyright changes should be propagated to any associated repositories
74 (eg Gnus, MH-E), but I think in every case this happens automatically
75 (?).
76
77 All README (and other such text files) that are non-trivial should
78 contain copyright statements and GPL license notices, exactly as .el
79 files do (see e.g. README in the top-level directory). Before 2007,
80 we used a simple, short statement permitting copying and modification
81 provided legal notices were retained. In Feb 2007 we switched to the
82 standard GPL text, on legal advice. Some older text files in etc/
83 should, however, keep their current licenses (see below for list).
84
85 For image files, the copyright and license details should be recorded
86 in a README file in each directory with images. (Legal advice says
87 that we need not add notices to each image file individually, if they
88 allow for that.). It is recommended to use the word "convert" to
89 describe the automatic process of changing an image from one format to
90 another (http://lists.gnu.org/archive/html/emacs-devel/2007-02/msg00618.html).
91
92
93 When installing a file with an "unusual" license (after checking first
94 it is ok), put a copy of the copyright and license in the file (if
95 possible. It's ok if this makes the file incompatible with its
96 original format, if it can still be used by Emacs), or in a README
97 file in the relevant directory.
98
99 The vast majority of files are copyright FSF and distributed under the
100 GPL. A few files (mainly related to language and charset support) are
101 copyright AIST alone, or both AIST and FSF. (Contact Kenichi Handa
102 with questions about legal issues in such files.) In all these cases,
103 the copyright years in each file should be updated each year.
104
105 There are some exceptions to the points in the previous paragraph, and
106 these are listed below for reference, together with any files where
107 the copyright needs to be updated in "unusual" ways.
108
109 If you find any other such cases, please consult to check they are ok,
110 and note them in this file. This includes missing copyright notices,
111 and "odd" copyright holders. In most cases, individual authors should
112 not appear in copyright statements. Either the copyright has been
113 assigned (check copyright.list) to the FSF (in which case the original
114 author should be removed and the year(s) transferred to the FSF); or
115 else it is possible the file should not be in Emacs at all (please
116 report!).
117
118 Note that it seems painfully clear that one cannot rely on commit logs,
119 or even ChangeLogs, for older changes. People often installed changes
120 from others, without recording the true authorship.
121
122 [For reference, most of these points were established via email with
123 rms, 2007/1, "Copyright years".]

204 Copyright information is duplicated in etc/ETAGS.README. Update that

206
207 Until 2007 etags.c was described as being copyright FSF and Ken Arnold.
208 After some investigation in Feb 2007, then to the best of our
209 knowledge we believe that the original 1984 Emacs version was based
210 on the version in BSD4.2. See for example this 1985 post from Ken Arnold:
211 <http://groups.google.com/group/mod.sources/browse_thread/thread/ffe5c55845a640a9>
212 I have received enough requests for the current source to ctags
213 to post it. Here is the latest version (what will go out with
214 4.3, modulo any bugs fixed during the beta period). It is the
215 4.2 ctags with recognition of yacc and lex tags added.
216
217 See also a 1984 version of ctags (no copyright) posted to net.sources:
218 <http://groups.google.com/group/net.sources/msg/a21b6c21be12a98d>
219 Version of etags.c in emacs-16.56 duplicates comment typos.
220
221 Accordingly, in Feb 2007 we added a 1984 copyright for the
222 University of California and a revised BSD license. The terms of
223 this require that the full license details be available in binary
224 distributions - hence the file etc/ETAGS.README. The fact that the
225 --version output just says "Copyright <year> FSF" is apparently OK
226 from a legal point of view.
227
228 lib-src/getopt1.c, getopt_int.h
229 - these are from the GNU C library. Leave the copyrights alone.
230
231 lisp/cedet/semantic/imenu.el
232 - See http://lists.gnu.org/archive/html/emacs-devel/2010-03/msg00410.html
233 in which Eric Ludlam established that the remaining contributions
234 from authors other than himself were negligible.
235
236 lisp/play/tetris.el
237 - no special rules about the copyright. We note here that we believe
238 (2007/1) there is no problem with our use of the name "tetris" or
239 the concept.
240 rms: "My understanding is that game rules as such are not copyrightable."
241 <http://lists.gnu.org/archive/html/emacs-devel/2007-01/msg00960.html>
242 rms: Legal advice is that we are ok and need not worry about this.
243
244
245 lisp/net/tramp.el
246 - there are also copyrights in the body of the file. Update these too.
247
248
249 lwlib/
250 rms (2007/02/17): "lwlib is not assigned to the FSF; we don't consider
251 it part of Emacs. [...] Therefore non-FSF copyrights are ok in lwlib."
252
253 NB don't change the GPL version used for lwlib .c and .h files (see
254 below).
255
256 FSF copyrights should only appear in files which have undergone
257 non-trivial cumulative changes from the original versions in the Lucid
258 Widget Library. NB this means that if you make non-trivial changes to
259 a file with no FSF copyright, you should add one. Also, if changes are
260 reverted to the extent that a file becomes basically the same as the
261 original version, the FSF copyright should be removed.
262
263 In my (rgm) opinion, as of Feb 2007, all the non-trivial files differ
264 significantly from the original versions, with the exception of
265 lwlib-Xm.h. Most of the changes that were made to this file have
266 subsequently been reverted. Therefore I removed the FSF copyright from
267 this file (which is arguably too trivial to merit a notice anyway). I
268 added FSF copyright to the following files which did not have them
269 already: Makefile.in, lwlib-Xaw.c, lwlib-int.h (borderline),
270 lwlib-utils.c (borderline), lwlib.c, lwlib.h.
271
272 Copyright years before the advent of public CVS in 2001 were those
273 when I judged (from the CVS logs) that non-trivial amounts of change
274 had taken place. I also adjusted the existing FSF years in xlwmenu.c,
275 xlwmenu.h, and xlwmenuP.h on the same basis.
276
277 Note that until Feb 2007, the following files in lwlib were lacking
278 notices: lwlib-int.h, lwlib.h, lwlib-Xaw.h, lwlib-Xlw.h, lwlib-utils.h
279
280 The following files did not list a Lucid copyright: xlwmenu.h,
281 xlwmenuP.h.
282
283 To the best of our knowledge, all the code files in lwlib were
284 originally part of the Lucid Widget Library, even if they did not say
285 so explicitly. For example, they were all present in Lucid Emacs 19.1
286 in 1992. The exceptions are the two Xaw files, which did not appear
287 till Lucid Emacs 19.9 in 1994. The file lwlib-Xaw.h is too trivial to
288 merit a copyright notice, but would presumably have the same one as
289 lwlib-Xaw.c. We have been unable to find a true standalone version of
290 LWL, if there was such a thing, to check definitively.
291
292 To clarify the situation, in Feb 2007 we added Lucid copyrights and
293 GPL notices to those files lacking either that were non-trivial,
294 namely: lwlib-int.h, lwlib.h, xlwmenu.h, xlwmenuP.h. This represents
295 our best understanding of the legal status of these files. We also
296 clarified the notices in Makefile.in, which was originally the
297 Makefile auto-generated from Lucid's Imakefile.
298
299 As of Feb 2007, the following files are considered too trivial for
300 notices: lwlib-Xaw.h, lwlib-Xlw.h, lwlib-utils.h.
301
302 The version of lwlib/ first installed in Emacs seems to be the same as
303 that used in Lucid Emacs 19.8 (released 6-sep-93); except the two Xaw
304 files, which did not appear till Athena support was added in Lucid
305 Emacs 19.9. In Lucid Emacs 19.1, all files were under GPLv1 or later,
306 but by Lucid Emacs 19.8, lwlib.c and xlwmenu.c had been switched to v2
307 or later. These are the versions that were first installed in Emacs.
308 So in GNU Emacs, these two files have been under v2 or later since
309 1994.
310
311 It seems that it was the intention of Lucid to use v1 or later
312 (excepting the two files mentioned previously); so this is the license
313 we have used when adding notices to code that did not have notices
314 originally. Although we have the legal right to switch to v2 or later,
315 rms prefers that we do not do so.
316
317
318 doc/*/doclicense.texi
319 - leave the copyright alone in this imported file.
320
321 doc/*/*.texi - All manuals should be under GFDL (but see below), and
322 should include a copy of it, so that they can be distributed
323 separately. faq.texi has a different license, for some reason no-one
324 can remember.
325 http://lists.gnu.org/archive/html/emacs-devel/2007-04/msg00583.html
326 http://lists.gnu.org/archive/html/emacs-devel/2007-04/msg00618.html
327
328 doc/misc/mh-e.texi is dual-licensed (GPL and GFDL) per agreement with
329 FSF (reconfirmed by rms Aug 25 2008). Discussion with
330 licensing@fsf.org starting on Thu, 07 Aug 2003 with subject:
331 "[gnu.org #58812] Changing license of MH-E manual"
332
333
334 msdos/is_exec.c, sigaction.c - these files are copyright DJ Delorie.
335 Leave the copyrights alone. Leave the Eli Zaretskii copyright in
336 is_exec.c alone. See the msdos/README file for the legal history of
337 these files.
338
339 msdos/sed*.inp - These files are copyright FSF and distributed under
340 an MIT-like license.
341
342
343 oldXMenu/
344 Keep the "copyright.h" method used by X11, rather than moving the
345 licenses into the files. Note that the original X10.h did not use
346 copyright.h, but had an explicit notice, which we retain.
347
348 If you make non-trivial changes to a file which does not have an FSF
349 notice, add one and a GPL notice (as per Activate.c). If changes to a
350 file are reverted such that it becomes essentially the same as the
351 original X11 version, remove the FSF notice and GPL.
352
353 Only the files which differ significantly from the original X11
354 versions should have FSF copyright and GPL notices. At time of writing
355 (Feb 2007), this is: Activate.c, Create.c, Internal.c. I (rgm)
356 established this by diff'ing the current files against those in X11R1,
357 and when I found significant differences looking in the ChangeLog for
358 the years they originated (the CVS logs are truncated before 1999). I
359 therefore removed the FSF notices (added in 200x) from the other
360 files. There are some borderline cases IMO: AddSel.c, InsSel.c,
361 XMakeAssoc.c, XMenu.h. For these I erred on the side of NOT adding FSF
362 notices.
363
364 With regards to whether the files we have changed should have GPL
365 added or not, rms says (2007-02-25, "oldXmenu issues"):
366
367 It does not make much difference, because oldXmenu is obsolete
368 except for use in Emacs (and it is not normally used in Emacs any
369 more either).
370
371 So, to make things simple, please put our changes under the GPL.
372
373 insque.c had no copyright notice until 2005. The version of insque.c
374 added to Emacs 1992-01-27 is essentially the same as insremque.c added
375 to glic three days later by Roland McGrath, with an FSF copyright and
376 GPL, but no ChangeLog entry:
377 <http://sources.redhat.com/cgi-bin/cvsweb.cgi/~checkout~/libc/misc/insremque.c?\
378 rev=1.1&cvsroot=glibc>
379 To the best of his recollection, McGrath (who has a copyright
380 assignment) was the author of this file (email from roland at frob.com
381 to rms, 2007-02-23, "Where did insque.c come from?"). The FSF
382 copyright and GPL in this file are therefore correct as far as we
383 understand it.
384
385 Imakefile had no legal info in Feb 2007, but was obviously based on
386 the X11 version (which also had no explicit legal info). As it was
387 unused, I removed it. It would have the same MIT copyright as
388 Makefile.in does now.
389
390
391 src/gmalloc.c
392 - contains numerous copyrights from the GNU C library. Leave them alone.
393
394 src/acldef.h, chpdef.h, ndir.h
395 - see comments below. These files are OK to be released with Emacs
396 22, but we may want to revisit them afterwards.

419
420 I don't remember writing it, but it reads like my prose and I believe
421 I wrote the feature(s) it's describing. So I would have been the
422 likeliest person to write it.
423
424 Odds are that I did, but I'm not certain.
425
426 Accordingly, FSF copyright was added.

430 - briefly removed due to legal uncertainly Jan-Mar 2007. The
431 relevant assignment is under "hp9k800" in copyright.list. File was
432 written by John V. Morris at HP, and disclaimed by the author and
433 HP. So this file is public domain.

436 K Rodgers changes
437 It was pointed out that K Rodgers only had assigments for VC and
438 ps-print, but had changed several other files. We tried to contact
439 him for a general assignment, but he proved uncommunicative (despite
440 initially indicating to rms he would sign an assignment). As a result, his
441 changes were removed and/or rewritten independently. For details, see
442 threads:

473 On legal advice from Matt Norwood, the following comment was added
474 to these files in Feb/Mar 2007:
475
476 The code here is forced by the interface, and is not subject to
477 copyright, constituting the only possible expression of the
478 algorithm in this format.
479
480 With the addition of this notice, these files are OK for the
481 upcoming Emacs-22 release. Post-release, we can revisit this issue
482 and possibly add a list of all authors who have changed these files.
483 (details in email from Matt Norwood to rms, 2007/02/03).
484
485 etc/ms-7bkermit
486 Says it was written by Andy Lowry and Joel Spolsky. No entry for
487 either in copyright.list. NB this file is not "constrained" like
488 ms-kermit (rms: "We know it isn't. A comment at the front says it has
489 other bindings which might be handy."). File removed March 2007.
490 Re-add if clear up status at some point.
491
492 etc/Xkeymap.txt
493 No info on author. File removed March 2007. rms: "It says it is
494 RLK's way of remapping his keyboard, so it is not constrained. I think
495 it was written by RLK. Let's delete it; if we contact RLK again, we
496 can put it back." Actually, RLK == Robert Krawitz has an Emacs
497 assignment. So this could be restored if it is still useful, but Jan Djärv
498 says it is obsolete:
499 <http://lists.gnu.org/archive/html/emacs-devel/2007-03/msg00673.html>
500
501 src/m/mips4.h, news-risc.h, pmax.h
502 src/s/aix3-2.h, bsd386.h, hpux8.h, hpux9.h, irix4-0.h, irix5-0.h,
503 netbsd.h, sol2-3.h, usg5-4-2.h
504 - all these (not obviously trivial) files were missing copyrights
505 till Feb 2007, when FSF copyright was added. Matt Norwood advised:
506
507 For now, I think the best policy is to assume that we do have
508 assignments from the authors (I recall many of these header files
509 as having been originally written by rms), and to attach an FSF
510 copyright with GPL notice. We can amend this if and when we
511 complete the code audit. Any additions to these files by
512 non-assigned authors are arguably "de minimis" contributions to
513 Emacs: small changes or suggestions to a work that are subsumed in
514 the main authors' copyright in the entire work.
515
516 Here is my (rgm) take on the details of the above files:
517
518 mips4.h
519 might be trivial? started trivial, been added to in tiny changes by
520 those with FSF assignment, often result of email suggestions by others.
521
522 news-risc.h
523 started trivial. Grown by tiny additions, plus chunk
524 from mips.h, which was and is Copyright FSF
525
526 pmax.h
527 started trivial. grown in tiny changes, except for maybe Jim Wilson's
528 comment.
529
530 ? irix4-0.h
531 I would say started non-trivial (1992, rms). only tiny changes since
532 installed.
533
534 ? irix5-0.h
535 I would say started non-trivial (1993, jimb, heavily based
536 on irix4-0.h). A few borderline non-tiny changes since.
537
538 usg5-4-2.h
539 started non-trivial, but was heavily based on usg5-4.h, which was and is
540 copyright FSF. only tiny changes since installed.
541
542 sol2-3.h
543 started trivial. only non-tiny change (1994) incorporated code from
544 usg5-4.h, which was and is copyright FSF.
545
546 aix3-2.h, bsd386.h, hpux8.h, hpux9.h, netbsd.h
547 started trivial, grown in tiny changes.
548
549 netbsd.h:
550 Roland McGrath said to rms (2007/02/17): "I don't really remember
551 anything about it. If I put it in without other comment, then probably
552 I wrote it myself."
553
554
555 Someone might want to tweak the copyright years (for dates before
556 2001) that I used in all these files.
557
558 Note: erring on the side of caution, I also added notices to some
559 files I thought might be considered non-trivial (if one includes
560 comment) in s/:
561 aix4-1.h hpux10.h irix6-0.h irix6-5.h
562 ptx4.h sol2.h
563
564 (everything with > 30 non-blank lines, which at least is _some_ kind of
565 system)
566
567
568 *** These are copyright issues that need not be fixed until after
569 Emacs 22 is released (though if they can be fixed before, that is
570 obviously good):
571
572
573 Is it OK to just `bzr remove' a file for legal reasons, or is
574 something more drastic needed? A removed file is still available from
575 the repository, if suitable options are applied. (This issue obviously
576 does not affect a release).
577 rms: will ask lawyer
578
579
580 Make sure that all files with non-standard copyrights or licenses are
581 noted in this file.
582
583
584 REMOVED etc/gnu.xpm, nt/icons/emacs21.ico, nt/icons/sink.ico
585 - Restore if find legal info. emacs21.ico is not due to Davenport.
586 Geoff Voelker checked but could not find a record of where it came
587 from.
588
589
590 etc/images
591 Image files from GTK, Gnome are under GPLv2 (no "or later"?). RMS will
592 contact image authors in regards to future switch to v3.
593
594
595 etc/TUTORIAL* (translations)
596 switch to GPL (see english TUTORIAL)
597 rms: "We can leave the TUTORIAL translations alone until their
598 maintainers update them."
599 Can adapt short license text from end of GPL translations at:
600 http://www.gnu.org/licenses/translations.html
601 Only a few sentences around the license notice need changing from
602 previous version.
603 Done: TUTORIAL.eo
604
605
606 *** These are copyright issues still to be addressed:
607
608 None known.
609
610
611 ** NOTES ON RELICENSING TO GPL3
612
613 The EMACS_22_BASE branch was changed to GPLv3 (or later) 2007/07/25.
614
615 Some notes:
616 (see http://lists.gnu.org/archive/html/emacs-devel/2007-07/msg01431.html)
617
618 1. There are some files in the Emacs tree which are not part of Emacs (eg
619 those included from Gnulib). These are all copyright FSF and (at time
620 of writing) GPL >= 2. rms says may as well leave the licenses of these
621 alone (may import them from Gnulib again). These are:
622
623 Gnulib:
624 src/getloadavg.c
625 src/gmalloc.c
626 src/md5.c
627 src/md5.h
628 src/mktime.c
629 src/strftime.c
630 src/termcap.c
631 src/tparam.c
632
633 Others:
634 config.guess
635 config.sub
636 doc/man/texinfo.tex
637
638 Note _not_ included in the above are src/regex.{c,h} (rms: "That
639 forked version is only in Emacs, so definitely relicense that."), and
640 oldXMenu/insque.c (rms: "We wrote that specifically for Emacs, so
641 definitely relicense that.").
642
643 2. The files that are copyright FSF and AIST, or AIST alone, should be
644 and were updated, ditto the oldXMenu files with FSF copyright, and
645 msdos/is_exec.c and sigaction.c.
646
647 3. lwlib/
648
649 Files originally in Lucid Widget Library were left alone (excludes
650 ChangeLog, etc), ie remain under GPL v1 or later, or v2 or later.
651 (rms: "We may as well leave this alone, since we are never going to
652 change it much.")
653
654 4. There are some files where the FSF holds no copyright. These were
655 left alone:
656
657 leim/MISC-DIC/CTLau-b5.html >= v2
658 leim/MISC-DIC/CTLau.html >= v2
659 (above included in lisp/international/titdic-cnv.el)
660 leim/MISC-DIC/pinyin.map >= v1
661 leim/MISC-DIC/ziranma.cin >= v1
662 leim/SKK-DIC/SKK-JISYO.L >= v2
663 leim/SKK-DIC/README >= v2
664 leim/ja-dic/ja-dic.el >= v2
665
666 5. At time of writing, some non-Emacs icons included from Gnome remain
667 under GPLv2 (no "or later"). See:
668
669 etc/images/gnus/README
670 etc/images/mail/README
671 etc/images/README
672 nt/icons/README
