May I publish a Windows Installer for GNU Emacs?

May I publish a Windows Installer for GNU Emacs?

[Frank Schmitt]

Hello

During the last days, I've created a Windows Installer for GNU
Emacs. Here's what it currently does:

After a welcome dialog, it shows the GPL and asks the user, if he
accepts it. If he does, he can now choose a directory to install Emacs
in. The installer now checks, if the environment variable HOME is
set. If it is not, the user is asked, if he wants the installer to set
it and prompted for a directory. Now the user can choose if he wants an
entry in the Start menu and if he wants one, in which folder it should
be created. Now the user can choose, if he wants shortcuts on the
desktop and the quicklaunch bar, too. After this the installation
begins, first all files which would be installed by a "make install"
are copied to the chosen folder, then the registry entries which would
normally be set by running addpm.exe are added and if the user choose
to set $HOME, the environment variable is set and the directory
created. If $HOME has been set by the installer, the user is now
prompted for a reboot and installation is finished.

My installer currently installs a CVS snapshot of Emacs' head from
09/09/03 plus the dll's needed to display inline images (from the
gnuwin32 project), but creating an installer for any other version of
Emacs is a matter of running a simple script.

I'd like to publish this installer (and an installer for latest stable
Emacs) on my website, is this OK? Or would you like to make this
installer "official"? (I'd be willing to keep it up-to-date)

If I publish it on my website, do I have to publish the sourcecode, too
or is it enough to say "Emacs' sources can be found on ftp.gnu.org or
any gnu mirror respectively by doing a CVS checkout (informations on how
to do this can be found on http://savannah.gnu.org/projects/emacs). The
sources for the image libraries used can be found on
http://gnuwin32.sourceforge.net/"?

The installer was created with the help of two free tools: Inno Setup 4
(http://www.jrsoftware.org/isinfo.htm OK, I don't really know if the
software can really be called free, it's published under a somewhat
BSD-like license, see http://www.jrsoftware.org/files/is/license.txt) to
create the installer and 7-zip (http://www.7-zip.org/ published under
the LGPL) to compress it to the size of 17.2 mb (uncompressed about
93mb).

This is nonsense.  There is no need to accept the GPL for installing
and using Emacs.

>From the GPL:

    Activities other than copying, distribution and modification are
    not covered by this License; they are outside its scope.  The act
    of running the Program is not restricted, and the output from the
    Program is covered only if its contents constitute a work based on
    the Program (independent of having been made by running the
    Program).

You can do anything permitted by copyright law with a GPL-covered
program _without_ accepting the license.  The GPL explicitly states:

      5. You are not required to accept this License, since you have
    not signed it.  However, nothing else grants you permission to
    modify or distribute the Program or its derivative works.  These
    actions are prohibited by law if you do not accept this License.
    Therefore, by modifying or distributing the Program (or any work
    based on the Program), you indicate your acceptance of this
    License to do so, and all its terms and conditions for copying,
    distributing or modifying the Program or works based on it.

So in short, an "Accept/Don't Accept" choice for installation is
completely nonsensical.  Instead you can pop up a _single_ button
that says

    "Thank you."

If you need two buttons, you can make them

    "Thank you." and "I knew that."

with identical action.

Can't say anything about the rest.

Ah OK, I must admit, that I have "stolen" this part from Gimps
installer, but I see your point and will remove it.

Actually, I suggest that you take David's advise do display the
following buttons: 

    "Thank you." and "I knew that."

instead of not displaying the GPL.  Why?  Free software is not as
well-known in the Windows world (although someone installing Emacs might
already have a clue) and I know maybe people that click "I accept"
without even reading anything when they encounter an EULA.  If they saw
Thank you." and "I knew that.", they might be surprised and read the
GPL.  Then that's one more person that goes "Wow, that's neat."

Well, in case my meaning got lost: it _was_ a serious proposal of mine
to display those buttons along with the GPL.  And the sad thing about
it is that people will tend to read the GPL because they would feel
insecure about what their choices might entail and what they will
subject themselves to making either.

Whereas they have no problem clicking on "I agree" to something they
have not even read through.

I see Peters and your point, however this is a bit tricky to do (the
licence dialog is a standard dialog in the setup creator, I'd have to
create a new dialog from scratch or modify the sources of the setup
creator and recompile it).

I'll see what I can do.

Heh.  My bet is that if they're ordinary users, they'll be peeved at
being tricked into reading the GPL to decide which button to push, and
discovering that it doesn't tell them! when they were planning on
ignoring any legal restrictions on use and redistribution in any case.

A message in that tone is not a constructive contribution to deciding
what we should do.

OK, here's a contructive version.

Paraphrase: Make sure that the dialog itself makes clear that use of
Emacs is entirely free under copyright law.  While to those in the
know, "Thanks!" and "I knew that!" are cute, the GNU GPL _is_ a legal
document.  Its purpose is likely to be quite unclear to the
uninitiated.  Those labels will occasionally be taken as a bad, if
well-intended, joke of uncertain meaning.

OTOH, I agree with the observation that users expect a EULA, and this
is an opportunity to put something useful in front of them.

Note that the GPL *is* a license, although not an "agreement".
Without it, the user may not make copies, which we consider a natural
part of ordinary usage.  Granted, most people will just burn a CD
containing the whole distribution, and thus trivially satisfy the
conditions.  But a license _is_ required, and there are some natural
ways to go wrong (for example, just copying the installed Emacs tree,
omitting the source distribution), so any humor may be a little risky,
legally speaking.

I suspect a terse statement of the four freedoms would fit and be
appropriate here.  Further, I would suggest that the GPL be presented
(1) as the legal statement of the FSF's responsibilities to the user
(NO WARRANTY etc), so please read that part, and (2) an invitation to
participate in improvement of the software.

With (2) in mind, you might consider substituting "How can I help?" or
"I'd like to know more!" for "I knew that!", and that button's action
would be to display some appropriate text.  Probably the whole GNU
Manifesto is too "heavy," but excerpts including the parts about "what
we need", plus text specifically explaining how important "ordinary
user" contributions such as bug reports and participation in c.emacs
and gnu.emacs.* are, might actually be quite frequently read.

Something like:

========================================================================

                  Thank you for choosing GNU Emacs.

Please read the "GNU General Public License" displayed below.

                               Summary

Under copyright law, you are free to run this copy of GNU Emacs.  The
following General Public License states and protects additional rights
that you possess.  You need not accept or decline the License; you
simply exercise those rights, as defined in the License, at your
option.  Please read it to learn precisely what they are.

  One of those rights is make additional copies of GNU Emacs for your
own use.  Another is to copy and redistribute it to your neighbors, as
long as you give them a copy of everything, just as you got it.  More,
you may add features, fix defects, or use parts of GNU Emacs for your
own purposes, and make and distribute copies of such derived software.

  In case of modification, we add more complex restrictions to ensure
that all users can exercise these rights.  According to law, if you
redistribute copies of the software, verbatim or modified, you must
follow the terms of the License.  Please read the License, so you may
freely share GNU Emacs with your neighbors according to its terms.

  This license is extended from the Free Software Foundation, and any
authors of modifications, to you.  Since all are free to modify and
redistribute this software, no one can accept liability for any
defects or problems that may arise in your use of GNU Emacs.  This is

GNU Emacs includes many contributions from both dedicated developers
and "just plain users".  If you will use GNU Emacs and share verbatim
copies with your neighbors, join us by clicking "Thank you all!" and
starting to use GNU Emacs.  If you would like to know how to contribute
more concretely, or how to use parts of GNU Emacs for your own
purposes, click "Tell me more."

["Thank you all!"]  ["That's great!  Tell me more, without legalese."]

========================================================================

Yeah, I know, all that's in the Preamble of the GPL.  But it would
require really fine print---bad associations, there---to get all those
statements into the first screen if we just dive into the GPL.  And
I'm sorry, I couldn't see a good way to get "free software" in there;
it really requires the supporting context that the Preamble gives.
Hopefully a well-designed screen can attract them to read the Preamble
(and the rest of the GPL).

The "without legalese" phrase is a little risky; people might
substitute clicking that button for reading the GPL.  However, this
could be considered a reasonable tradeoff to get many people to read
anything at all.  And sections of the GPL itself, plus pointers back
to the full document, would be natural to include anyway.

I considered that the GPL itself could be invoked by a button, but I
think it's most likely to be read if the title is visible along with
the summary.

Pity.  I like that, but then I am biased to my own jokes.

Not really.  It's just that without a licence, the usefulness of the
software would be less.

This is incorrect.  It sounds like you can cherrypick.  But you
either have to accept the license as a whole, or decline it.

That is wrong.  You need to follow the terms of a licence only if you
have agreed to a licence (that's why there is such a joke like
click-through licences).

Copyright law defaults to allowing you to pass on or sale your own
acquired copy of an acquired piece of copyrighted material.  Only
additional copies are not permitted to be circulated, unless you have
negotiated a licence permitting it.

And so on.  It's a nice idea to write some brief explanation to a
legal document, but if one does, it takes quite a lot of checking to
make sure one does not tell people something wrong.

The context clearly implies "required _to copy and distribute_".

Substitute "You need not accept or decline the License at this time.
At your option, at any time you may simply exercise those additional
rights, which implies acceptance."

Of course cherrypicking is OK.  You may choose to exercise any, all,
or none of the options the GPL offers.  They don't constrain each
other as far as I can tell.

Read Clause 5, please: distribution constitutes acceptance.  If this
needs to be spelled out precisely, then most of Clause 5 would have to
be reiterated, making the value of a summary questionable.  (It's
already too bulky.)  Just reduce the whole summary to:

Under copyright law, you are free to run this copy of GNU Emacs.  The

restricted rights to copy, modify, and distribute GNU Emacs that you

========================================================================

That's pretty good, but I think that the opportunity to put a more
descriptive summary in front of the reader shouldn't be wasted.
Remember, we're talking about a population of users which is much less
likely to be interested in those rights than we are, but we'd still
like to educate them.  They already know very well how to click on
"Accept" without reading; let's not tickle that reflex.

BTW, if click-through is a joke, I hate to think what you'd call the
GPL.  It doesn't even offer you a chance to click.

    David> Copyright law defaults to allowing you to pass on or sale

In English in this context "redistribute copies of" will normally be
taken as equivalent to "copy and redistribute" (the unambiguous but
rather awkward phrase used by the GPL).  I could change it to that,
but I really don't think it's necessary.

AFAICT I wrote nothing that is factually incorrect (there are a few
typos and grammar errors), when interpreted idiomatically in English.
I was careful (twice, in fact) to refer to the License as the
definition of those rights, and to tell the reader to read it.  If
that's not good enough, then nothing can be.  (That's not rhetoric; I
was fully aware when I wrote the post that anything less than the
exact text of the GPL might be considered unacceptable by the lawyers.)

Copyright law allows you making personal copies and distributing to a
computer on which you'd like to use it.

I can redistribute but don't need to heed that I need to include the
source code?  Hardly.

It is not the purpose of the summary to state incorrectly what can be
read more fully.  It's perfectly fine to just keep out points from a
summary or refer to the full version.  But one should avoid stating
misleading things.

Actually, not even that is true.  If I steal some Linux CD's
including only free software, I don't acquire the right to run the
software.  If I steal an internal version derived from Emacs from a
company's server, it is illegal for me to run the stolen software or
redistribute it.

How about:

Copyright law regulates what you can do with a copy of software you
legally acquired unless you agreed to additional licensing terms.
While you don't need to agree to the GPL in order to run Emacs or make
copies for personal use, you lose nothing by agreeing, since that just
gives you additional rights.

Right.  And it does not need to.  Since it makes it optional whether
you want to agree to the licence or not.  You can claim "Clicking
some stupid button on a computer does not constitute legally binding
agreement."

But the GPL does not have to rely on such stupidities because it does
not restrict what copyright allows you, but extends it.  Not agreeing
buys you nothing.

    Actually, not even that is true.  If I steal some Linux CD's

    software.

If they are truly Linux CDs, you could not run them anyway, since a
kernel alone won't run.  But if they were CDs of a released version of
GNU/Linux, then you could run them.

I discussed this issue with our lawyer, and we concluded that if there
was no trade secret in the code you stole, you do have the GPL rights
in using it.

Sure?  It is not copyright that is relevant here, it is the usual
criminal code.  Copyright tells you about your rights when you have
acquired a copy of something, but theft is not a legal acquisition.
You are not permitted to make use of stolen goods.  You could not sue
for breach of copyright but for employment of stolen goods, and the
party that could sue is not the copyright holder, but rather the legal
owner of the copy.

But I don't see how the recipient of a theft would gain license rights
unless being granted those after the fact from the copyright holder.
There was no transaction putting him into legal possession of a copy.

The GPL is not something floating in the air.  You have to be given it
before it applies.  Stealing it along with software does not make it a
valid licence, just as stealing a house contract does not make me
owner of the house.

Re: May I publish a Windows Installer for GNU Emacs?

[Oliver Scholz]

FWIW this point is mentioned in the GPL FAQ. They distinguish the
case of stealing an unpublished CD from stealing a CD that has been
released elsewhere.

http://www.gnu.org/licenses/gpl-faq.html#StolenCopy

        If someone steals a CD containing a version of a GPL-covered
        program, does the GPL give him the right to redistribute that
        version?

        If the version has been released elsewhere, then the thief
        probably does have the right to make copies and redistribute
        them under the GPL, but if he is imprisoned for stealing the
        CD he may have to wait until his release before doing so.

        If the version in question is unpublished and considered by a
        company to be its trade secret, then publishing it may be a
        violation of trade secret law, depending on other
        circumstances. The GPL does not change that. If the company
        tried to release its version and still treat it as a trade
        secret, that would violate the GPL, but if the company hasn't
        released this version, no such violation has occurred.

I find this interpretation more than dubious.  If the version has
been released "elsewhere", that does not give the thief the right to
make copies and redistribute them.  It only gives the people I have
released the software to those rights, and those that they have
chosen themselves to pass the software onto.

In all cases, copyright law does not apply to the media, but rather
property law concerning the copies that may not be used for any
purpose legally, including using as coasters.  When the thief chooses
to redistribute the software by copying from them, this is

a) a criminal offense, since he makes use of stolen goods
b) not covered by a legal licence.

The media owner can sue for a), the copyright holder might then choose
to sue for damages because of b).  Of course, the amount of damages
that can be claimed before court depend on the kind of circulation
that exists legally.  It would be pretty much useless for the FSF to
sue for redistributed gcc copies from stolen CDs, for example.  But
that does not magically make the act legal or give the thiefs any
rights, it just makes it unlikely that he will get sued.  Things are
different with specialized software under the GPL that is handed out
at high price to only selected parties: there it would be reasonably
easy to show damage.

Or when I am developing GPLed packages under contract, I plan to
release to the public eventually.  If somebody steals my work and
sends it on before the time, I can lose my payments.  Also, I can get
into a lot of additional work dealing with unnecessary bug reports if
unreleased versions are floating around.

That's right, for parts of the work already GPLed.

However, if there is any proprietary (ie, not specifically licensed
under the GPL) code included, then it is _not_ covered by the GPL.  As
long as you have not distributed that code, you retain copyright, ie,
all rights, by default.  Since you haven't distributed, you have done
nothing to require that your code be GPLed, even if you have accepted
the GPL itself (eg, by past redistribution of verbatim copies).  So
you can sue the thief under copyright law, and you can reclaim copies
from third parties.

I think this preserves all the rights to "work-in-progress" that David

Yes, it can.  See clause 0.  This could be useful: suppose you get hit

to a library, and now anyone who reads them may copy and publish
because it's under the GPL.  Very hypothetical, of course.

That is not one of the options that the GPL offers.  Your claim is

You have amply proved that there is no way to avoid misunderstanding

As a suggestion, the first couple of paragraphs of the emacs manual

What I've done now is to display the GPL after installation is
finished, the user hasn't to say something like "I accept" but to push
a button labelled "OK".

Regarding the sources: I've limited webspace, so I've just mailed the
administrator of the university where I study, if I can put the sources
on their ftp server, if he says it's ok, I'll publish the installer
this week.

Don't know how you are setting the variable on W9x/Me, but on
NT/W2K/XP, you don't needs a reboot for this.  I think you need to
send a notication message so that the Windows Explorer picks up the
new variable, but that's all.

Windows Explorer doesn't need it... Emacs (and cygwin if you have that
installed) need it, but they'll pick it up just be restarting the app.
If you set it at install, the first time emacs is started, it will
pick up $HOME.

I apologise if you've tried this and verified it to be the case, but
I would have expected a notification message to be required, since
Emacs is started as a subprocess of explorer.exe, and inherits its
environment. Perhaps you are thinking of the case where a user
manually changes the environment using the control panel applet, in
which case, the applet will take care of sending this notification
message.

Well, if it isn't necessary anymore, why is it done when installing via
make install?

I'm adding the environment variables und NT systems by adding a key to
the registry under HKCU/Environment and on 9x systems by modifying
autoexec.bat. In both cases you have to restart (ok, on NT systems, it's
enough to log out and log in again) to make changes have effect. Their
might be other solution, but I don't know about them.

I don't exactly know.  Probably because nobody bothered to remove the
code from the Makefile.  Or maybe it's to make certain debugging
scenarios easier, as the defaults are to use the files as installed in
relation to the binary, which is not always what you want for
debugging.

Anyway I believe the recommended way of installing Emacs on Windows
these days is just unpacking the binary archive and starting
runemacs.exe, without an installer and without addpm.exe.  So these
settings are not needed obviously.  AFAIK the settings are set as
environment variables by runemacs.exe, based on the executable path,
before runemacs.exe hands over to emacs.exe.

I think the message WM_SETTINGCHANGE is the one to send, check MSDN
for usage.  I'm slightly irritated that the install framework that you
use doesn't have prepackaged functions for this task.

Thanks, I'll look it up. The install framework has no predefined
functionality yet to update environment variables, so I had to do this
in a script manually.

Yes, I'd of course be interested in the code, however I doubt that a
stand-alone installer written from scratch can be as solid (e.g. in
terms of uninstalling, rolling back changes when an error occurs during
installing etc.) and easy to maintain as an installer produced by a
tool, developed simply for the purpose of building installers.

OK, it installs binaries compiled by me of the CVS snapshot.

There are no legal issues, I just use the tools to create the
installer, they aren't part of it.

Just to give you an idea what the difference is: I created the install
by running this script, the rest does Inno Setup for me:
