Licensing question about font files

Hi All,

The last versions of TeXmacs come with an optional package of
extra type 1 fonts, which were generated by me from the corresponding
TeX/LaTeX fonts using the autotrace program. Several people complained
that I did not include a license file yet. My question: under which
license should I make the fonts available? Can I distribute them
under the GNU GPL (my prefered solution), or am I obliged to distribute
them under the LaTeX Project Public License?

Best wishes, Joris

As I read the LaTeX Project Public License [1], you are clearly
allowed to distribute derived works iff the license in question
satisfies the 6th clause of the LPPL (written in §10). In case you
would provide the derived work (I consider your font package being
one) you would need to also provide the font files in a form that is
prefered for modification.

But I see another problem with distributing the fonts package with the
GPL. I do see differences between the GPL and §6 of the LPPL: part a)
and b) are covered by the GPL, as it requires the same, but d) is
not. The GPL does not require anybody to include or link the
unmodified LaTeX in a derived work. So somebody could base a work off
your GPLed fonts package and remove the reference to LaTeX (the
unmodified, original work). This is allowed by the GPL but not by the
LPPL.

[bug] segv Crash editing diagram moving multiple labels

Version: 1:1.0.6-2ubuntu1

Create a diagram, and then make a few lines an a few text labels.
Select the move tool, and grab the text label with the left mouse
button, and drag it to a new location, then let go of the left button.
Move the pointer outside of the label, and see that it is surrounded by
a red box.  Left-click in a clear area, and the label will now move with
the mouse.  Now right-click once, and see that all of the labels are
selected.  Now left-click twice, and TeXmacs will crash with a
segmentation fault.

[For packagers] New font packages now carry a license

Hi all,

The extra font packages now carry license information.
So this should no longer be an obstacle for not using them
(like it was for the Debian distribution).

Best wishes, Joris

---------------
P.S.: by lazyness, the new font packages still carry the old version number.

Almost. ;-)

I am glad to see that we are making progress in this and I have
checked your provided license against the terms provided in the source
files of the fonts, and everthing seems to be ok so far.

I only have one issue left: I can't figure out where you got the fonts
in type1/la/* from. Searching for their basenames on ctan.org does not
yield any results, neither do the fonts in
http://ctan.org/tex-archive/fonts/la/ seem to be the source for
them. The LA and LLA fonts from there also carry a strange licence
that does not explicitly allow modification, just redistribution as a
whole, without removing any parts.

It'd be nice if you clarified the origin of the fonts in type1/la/*. I
have found only a few references to them via google, but none of them
were useful besides your Makefile used to create them. ;-)

Thank you,
      René

They are standard in TeTeX.

Thank you, I have found them in the original TeTeX distribution
now. (they carry different names there)

I fully understand that you are fed up. I am not bugging you about
license concerns because it gives me joy either. It's just something
that has to be clear for redistribution. Thank you for your patience
in this.

Now that the origin of the la/ fonts is clear, this is luckily not
necessary.

This is true, of course. It's just that it was not obvious until now
that the la/ directory is generated from parts of the standard TeTeX
distribution.

All right, so I assume that things are OK then.

I am not upset against anyone in particular,
but I just no longer have time to spend on this kind of nonsense.

TeXmacs server

Hi *,

I am slowly but surely resuming my work on TeXmacs.
The new version 1.0.6.2 comes with a first version of
a TeXmacs server, futuring secure communications with
TeXmacs over the web. This is still experimental,
but it would be nice if some people could test.
After installation of TeXmacs-1.0.6.2, do

	Tools -> Remote -> Login -> New account

to create an account on the TeXmacs server and

	Tools -> Remote -> Login -> Login

in order to log in. Then connect to a chatroom in

	Tools -> Remote -> Chat -> ...

Don't bother about the password prompts for the moment;
they will be made invisible later. The accounts will
probably be removed at the next version of TeXmacs
(further security fixes), but it would be nice to see
whether things already do work more or less.

Best wishes, Joris
