A "license notice" is a statement of permissions, and is usually much longer, eg the text "GNU Emacs is free software...".  Glenn Morris committed Feb 16, 2007 16 17 Summary for the impatient:  Glenn Morris committed Mar 05, 2007 18 1. Don't add code to Emacs written by someone other than yourself  Glenn Morris committed Mar 05, 2007 19 20 21 22 23 24 without thinking about the legal aspect. Even if the changes are trivial, consider if they combine with previous changes by the same author to make a non-trivial total. If so, make sure they have an assignment. If adding a whole file adjust the copyright statements in the file.  Paul Eggert committed Nov 19, 2014 25 2. When installing code written by someone else, the commit  Glenn Morris committed Mar 05, 2007 26 should be in the name of the author of the code, not the person who  Eric S. Raymond committed Oct 25, 2014 27 installs it. Also use commit's "--author" option.  Glenn Morris committed Oct 17, 2011 28 Do not install any of your own changes in the same commit.  Glenn Morris committed Mar 05, 2007 29 30  3. With images, add the legal info to a README file in the directory  Glenn Morris committed Feb 16, 2007 31 32 containing the image.  Glenn Morris committed Mar 05, 2007 33 4. If you add a lot of text to a previously trivial file that had no  Glenn Morris committed Feb 16, 2007 34 35 legal notices, consider if you should add a copyright statement.  Glenn Morris committed Mar 05, 2007 36 5. Please don't just add an FSF copyright without checking that is the  Glenn Morris committed Feb 27, 2007 37 38 right thing to do.  Glenn Morris committed Feb 16, 2007 39   Glenn Morris committed Jan 16, 2010 40 Every non-trivial file distributed through the Emacs repository should be  Glenn Morris committed Jan 28, 2007 41 42 self-explanatory in terms of copyright and license. This includes files that are not distributed in Emacs releases (for example, the  Glenn Morris committed Jan 16, 2010 43 admin/ directory), because the whole Emacs repository is publicly  Glenn Morris committed Jan 28, 2007 44 45 46 47 available. The definition of triviality is a little vague, but a rule of thumb is that any file with less than 15 lines of actual content is trivial. If  Phillip Lord committed Mar 07, 2017 48 49 50 a file is auto-generated (eg ldefs-boot.el) from another one in the repository, then it does not really matter about adding a copyright statement to the generated file.  Glenn Morris committed Jan 28, 2007 51   Glenn Morris committed Feb 19, 2007 52 53 54 55 56 57 58 59 Legal advice says that we could, if we wished, put a license notice even in trivial files, because copyright law in general looks at the overall work as a whole. It is not _necessary_ to do so, and rms prefers that we do not. This means one needs to take care that trivial files do not grow and become non-trivial without having a license added. NB consequently, if you add a lot of text to a small file, consider whether your changes have made the file worthy of a copyright notice, and if so, please add one.  Glenn Morris committed Feb 15, 2007 60   Glenn Morris committed Feb 28, 2007 61 62 63 It can be helpful to put a reminder comment at the start of a trivial file, eg: "add a license notice if this grows to > 10 lines of code".  Glenn Morris committed Jan 28, 2007 64 The years in the copyright notice should be updated every year (see  Glenn Morris committed Jan 08, 2009 65 file "years" in this directory). The PDF versions of refcards etc  Glenn Morris committed Jan 28, 2007 66 67 68 should display copyright notices (an exception to the rule about "generated" files), but these can just display the latest year. The full list of years should be kept in comments in the source file. If  Glenn Morris committed Jan 16, 2010 69 70 these are distributed in the repository, check in a regenerated version when the tex files are updated.  Glenn Morris committed Jan 28, 2007 71 72 73 74 75  Copyright changes should be propagated to any associated repositories (eg Gnus, MH-E), but I think in every case this happens automatically (?).  Glenn Morris committed Feb 11, 2007 76 77 All README (and other such text files) that are non-trivial should contain copyright statements and GPL license notices, exactly as .el  Glenn Morris committed Feb 16, 2007 78 files do (see e.g. README in the top-level directory). Before 2007,  Glenn Morris committed Feb 11, 2007 79 80 we used a simple, short statement permitting copying and modification provided legal notices were retained. In Feb 2007 we switched to the  Glenn Morris committed Feb 16, 2007 81 82 standard GPL text, on legal advice. Some older text files in etc/ should, however, keep their current licenses (see below for list).  Glenn Morris committed Jan 28, 2007 83   Glenn Morris committed Feb 11, 2007 84 85 86 For image files, the copyright and license details should be recorded in a README file in each directory with images. (Legal advice says that we need not add notices to each image file individually, if they  Glenn Morris committed Feb 14, 2007 87 88 89 90 allow for that.). It is recommended to use the word "convert" to describe the automatic process of changing an image from one format to another (http://lists.gnu.org/archive/html/emacs-devel/2007-02/msg00618.html).

It's ok if this makes the file incompatible with its original format, if it can still be used by Emacs), or in a README file in the relevant directory. The vast majority of files are copyright FSF and distributed under the GPL. A few files (mainly related to language and charset support) are copyright AIST alone, or both AIST and FSF. (Contact Kenichi Handa with questions about legal issues in such files.) In all these cases, the copyright years in each file should be updated each year. There are some exceptions to the points in the previous paragraph, and these are listed below for reference, together with any files where the copyright needs to be updated in "unusual" ways. If you find any other such cases, please consult to check they are ok, and note them in this file. This includes missing copyright notices, and "odd" copyright holders. In most cases, individual authors should not appear in copyright statements. Either the copyright has been assigned (check copyright.list) to the FSF (in which case the original author should be removed and the year(s) transferred to the FSF); or else it is possible the file should not be in Emacs at all (please report!).  Glenn Morris committed Jan 16, 2010 117 Note that it seems painfully clear that one cannot rely on commit logs,  Paul Eggert committed Nov 19, 2014 118 119 or even change log entries, for older changes. People often installed changes from others, without recording the true authorship.

Update that file too. Until 2007 etags.c was described as being copyright FSF and Ken Arnold. After some investigation in Feb 2007, then to the best of our knowledge we believe that the original 1984 Emacs version was based on the version in BSD4.2. See for example this 1985 post from Ken Arnold: I have received enough requests for the current source to ctags to post it. Here is the latest version (what will go out with 4.3, modulo any bugs fixed during the beta period). It is the 4.2 ctags with recognition of yacc and lex tags added. See also a 1984 version of ctags (no copyright) posted to net.sources: Version of etags.c in emacs-16.56 duplicates comment typos. Accordingly, in Feb 2007 we added a 1984 copyright for the University of California and a revised BSD license. The terms of this require that the full license details be available in binary  Glenn Morris committed Mar 01, 2007 212 213 214  distributions - hence the file etc/ETAGS.README.

[...] Therefore non-FSF copyrights are ok in lwlib."  Glenn Morris committed Mar 01, 2007 238 239 240 NB don't change the GPL version used for lwlib .c and .h files (see below).  Glenn Morris committed Feb 27, 2007 241 242 243 244 245 246 247 248 249 250 251 252 253 254 255 256 257 258 259 260 261 262 263 264 265 266 267 268 269 270 271 272 273 274 275 276 277 278 279 280 281 282 283 284 285 286 FSF copyrights should only appear in files which have undergone non-trivial cumulative changes from the original versions in the Lucid Widget Library. NB this means that if you make non-trivial changes to a file with no FSF copyright, you should add one. Also, if changes are reverted to the extent that a file becomes basically the same as the original version, the FSF copyright should be removed. In my (rgm) opinion, as of Feb 2007, all the non-trivial files differ significantly from the original versions, with the exception of lwlib-Xm.h. Most of the changes that were made to this file have subsequently been reverted. Therefore I removed the FSF copyright from this file (which is arguably too trivial to merit a notice anyway). I added FSF copyright to the following files which did not have them already: Makefile.in, lwlib-Xaw.c, lwlib-int.h (borderline), lwlib-utils.c (borderline), lwlib.c, lwlib.h. Copyright years before the advent of public CVS in 2001 were those when I judged (from the CVS logs) that non-trivial amounts of change had taken place. I also adjusted the existing FSF years in xlwmenu.c, xlwmenu.h, and xlwmenuP.h on the same basis. Note that until Feb 2007, the following files in lwlib were lacking notices: lwlib-int.h, lwlib.h, lwlib-Xaw.h, lwlib-Xlw.h, lwlib-utils.h The following files did not list a Lucid copyright: xlwmenu.h, xlwmenuP.h. To the best of our knowledge, all the code files in lwlib were originally part of the Lucid Widget Library, even if they did not say so explicitly. For example, they were all present in Lucid Emacs 19.1 in 1992. The exceptions are the two Xaw files, which did not appear till Lucid Emacs 19.9 in 1994. The file lwlib-Xaw.h is too trivial to merit a copyright notice, but would presumably have the same one as lwlib-Xaw.c. We have been unable to find a true standalone version of LWL, if there was such a thing, to check definitively. To clarify the situation, in Feb 2007 we added Lucid copyrights and GPL notices to those files lacking either that were non-trivial, namely: lwlib-int.h, lwlib.h, xlwmenu.h, xlwmenuP.h. This represents our best understanding of the legal status of these files. We also clarified the notices in Makefile.in, which was originally the Makefile auto-generated from Lucid's Imakefile. As of Feb 2007, the following files are considered too trivial for notices: lwlib-Xaw.h, lwlib-Xlw.h, lwlib-utils.h.  Glenn Morris committed Mar 01, 2007 287 288 289 290 291 292 293 294 295 296 297 298 299 300 301 The version of lwlib/ first installed in Emacs seems to be the same as that used in Lucid Emacs 19.8 (released 6-sep-93); except the two Xaw files, which did not appear till Athena support was added in Lucid Emacs 19.9. In Lucid Emacs 19.1, all files were under GPLv1 or later, but by Lucid Emacs 19.8, lwlib.c and xlwmenu.c had been switched to v2 or later. These are the versions that were first installed in Emacs. So in GNU Emacs, these two files have been under v2 or later since 1994. It seems that it was the intention of Lucid to use v1 or later (excepting the two files mentioned previously); so this is the license we have used when adding notices to code that did not have notices originally. Although we have the legal right to switch to v2 or later, rms prefers that we do not do so.

Note that the original X10.h did not use copyright.h, but had an explicit notice, which we retain. If you make non-trivial changes to a file which does not have an FSF notice, add one and a GPL notice (as per Activate.c). If changes to a file are reverted such that it becomes essentially the same as the original X11 version, remove the FSF notice and GPL. Only the files which differ significantly from the original X11 versions should have FSF copyright and GPL notices. At time of writing (Feb 2007), this is: Activate.c, Create.c, Internal.c. I (rgm) established this by diff'ing the current files against those in X11R1, and when I found significant differences looking in the ChangeLog for the years they originated (the CVS logs are truncated before 1999). I therefore removed the FSF notices (added in 200x) from the other files. There are some borderline cases IMO: AddSel.c, InsSel.c, XMakeAssoc.c, XMenu.h. For these I erred on the side of NOT adding FSF notices. With regards to whether the files we have changed should have GPL added or not, rms says (2007-02-25, "oldXmenu issues"): It does not make much difference, because oldXmenu is obsolete except for use in Emacs (and it is not normally used in Emacs any more either). So, to make things simple, please put our changes under the GPL. insque.c had no copyright notice until 2005. The version of insque.c added to Emacs 1992-01-27 is essentially the same as insremque.c added to glic three days later by Roland McGrath, with an FSF copyright and GPL, but no ChangeLog entry: To the best of his recollection, McGrath (who has a copyright assignment) was the author of this file (email from roland at frob.com to rms, 2007-02-23, "Where did insque.c come from?"). The FSF copyright and GPL in this file are therefore correct as far as we understand it. Imakefile had no legal info in Feb 2007, but was obviously based on the X11 version (which also had no explicit legal info). As it was unused, I removed it. It would have the same MIT copyright as Makefile.in does now.

Matt Norwood advised: For now, I think the best policy is to assume that we do have assignments from the authors (I recall many of these header files as having been originally written by rms), and to attach an FSF copyright with GPL notice. We can amend this if and when we complete the code audit. Any additions to these files by non-assigned authors are arguably "de minimis" contributions to Emacs: small changes or suggestions to a work that are subsumed in the main authors' copyright in the entire work. Here is my (rgm) take on the details of the above files: ? irix5-0.h I would say started non-trivial (1993, jimb, heavily based on irix4-0.h). A few borderline non-tiny changes since. usg5-4-2.h started non-trivial, but was heavily based on usg5-4.h, which was and is copyright FSF. only tiny changes since installed.
