longer, eg the text "GNU Emacs is free software...".
+Summary for the impatient:
+
+1. Don't add a file to Emacs written by someone other than yourself
+without thinking about the legal aspect (make sure they have an
+assignment, adjust the copyright statements in the file). NB the
+ChangeLog entry should be in the name of the author of the code, not
+the person who installs it.
+
+2. With images, add the legal info to a README file in the directory
+containing the image.
+
+3. If you add a lot of text to a previously trivial file that had no
+legal notices, consider if you should add a copyright statement.
+
+
Every non-trivial file distributed through the Emacs CVS should be
self-explanatory in terms of copyright and license. This includes
files that are not distributed in Emacs releases (for example, the
CVS, then it does not really matter about adding a copyright statement
to the generated file.
-However, here is a quote from Matt Norwood (Software Freedom Law
-Center) that suggests we should revise the above policy about trivial
-files:
-
- If FSF has a strong policy reason notices off of files it
- considers "trivial", this will take a lot more bookkeeping; it
- also runs the risk of these "trivial" files later growing into
- non-trivial files, and being in the tree without any record of
- authorship. All in all, I think it's a better policy to attach the
- notice and let future authors decide if something is trivial when
- they want to reuse it elsewhere.
- [...]
- In general, copyright law will step back and look at the overall "work"
- consisting of all the assembled components working together as a system;
- it will apply protection and permissions to this system, not to its
- subcomponents. If parts of it are recombined into another system, it
- will consider the protections and permissions for each of the source
- components only in order to assess the overall status of the work again.
- The assessment of whether a set of components is entitled to copyright
- protection is the degree to which they display "creativity": not as
- atomic units, but as parts of a system working in concert. Thus, several
- "trivial" components working together in some coherent system might be
- protectible.
+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.
The years in the copyright notice should be updated every year (see
file "years" in this directory). The PS versions of refcards etc
All README (and other such text files) that are non-trivial should
contain copyright statements and GPL license notices, exactly as .el
-files do (see e.g. README in the top-level directory). (Before 2007,
+files do (see e.g. README in the top-level directory). Before 2007,
we used a simple, short statement permitting copying and modification
provided legal notices were retained. In Feb 2007 we switched to the
-standard GPL text, on legal advice.)
+standard GPL text, on legal advice. Some older text files in etc/
+should, however, keep their current licenses (see below for list).
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
-allow for that.)
+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).

When installing a file with an "unusual" license (after checking first
it is ok), put a copy of the copyright and license in the file (if

+ - all these (not obviously trivial) files were missing copyrights
+ till Feb 2007, when FSF copyright was added. 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:
+
+mips4.h
+ might be trivial? started trivial, been added to in tiny changes by
+ those with FSF assignment, often result of email suggestions by others.
+
+news-risc.h
+ started trivial. Grown by tiny additions, plus chunk
+ from mips.h, which was and is Copyright FSF
+
+pmax.h
+ started trivial. grown in tiny changes, except for maybe Jim Wilson's
+ comment.
+
+? irix4-0.h
+ I would say started non-trivial (1992, rms). only tiny changes since
+ installed.
+
+? irix5-0.h
+ I would say started non-trivial (1993, jimb, heavily based
+ on irix4-0.h). A few borderline non-tiny changes since.
+
+? isc2-2.h
+ started trivial. 2 non-tiny change, in 1993. looks to
+ be made up of several small tweaks from various sources. maybe
+ non-tiny total changes from Karl Berry (no emacs assignment).
+
+osf1.h
+ started trivial. grown in tiny changes (one borderline tiny change
+ by fx in 2000, but most code was later removed). non-tiny addition
+ in 2002 from m/alpha.h, but that was and is copyright FSF.
+
+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.
+
+sol2-3.h
+ started trivial. only non-tiny change (1994) incorporated code from
+ usg5-4.h, which was and is copyright FSF.
+
+aix3-2.h, bsd386.h, hpux8.h, hpux9.h, netbsd.h, sunos4-0.h
+ started trivial, grown in tiny changes.
+
+netbsd.h:
+Roland McGrath said to rms (2007/02/17): "I don't really remember
+anything about it. If I put it in without other comment, then probably
+I wrote it myself."
+
+
+Someone might want to tweak the copyright years (for dates before
+2001) that I used in all these files.
+
+Note: erring on the side of caution, I also added notices to some
+files I thought might be considered non-trivial (if one includes
+comment) in s/:
+ aix4-1.h hiuxmpp.h hiuxwe2.h hpux10.h irix6-0.h irix6-5.h isc3-0.h

-All README (and other such files) that are non-trivial and were added
-by Emacs developers need copyright statements and copying permissions.
- missed any?
- etc/BABYL?
- lisp/term/README?
- borderline "trivial" cases (see below)...?
-These should use the standard GPL text (same as .el files), rather
-than the short notices we have been using till now.
-rms: "If a README file is under 60 lines long, using the long version
-might be ugly. Please tell me if you encounter one that is under 60
-lines."
+etc/gnus-logo.eps, gnus-booklet.ps, gnus-refcard.ps
+ just to be safe, papers are on the way for the "Gnus logo", even
+ though it is very similar to the already-assigned "Emacs logo".
-Clarify the legal status of image files. It's not necessary to put a
-notice in each image (where the format allows it). It's OK to put the
-information in a README file in the associated directory. Files can be
-listed in groups. See etc/README for an example.
-Image files to consider:
- etc/images/gnus/bar, dead, gnntg, gnus-pointer, gnus, important,
- kill-group, reverse-smile, rot13, unimportant
- etc/images/smilies/
-rms: "Can you find this by searching for items in copyright.list that
-assign images for Emacs?" [this suggests we ask Bill Wohler]

-etc/e/eterm-color.ti - no copyright
- rms: "I think that is not copyrightable under the merger doctrine
- because the entries are all forced. At least that is the case in the
- US; I am not sure whether we can rely on that in general."
+etc/TUTORIAL* (translations)
