Thomas Esser had five possibilities how to react to the reported licence
1. do nothing: that would mean that the licence violation would not be
2. to remove the whole tetex-texmf-3.0.tar.gz from CTAN: that would mean
that the license violation would be corrected but teTeX 3.0 would not be
usable never more.
3. to remove the relevant files (csplain.ini etc.) from the
tetex-texmf-3.0.tar.gz archive: that would mean that the license violation
would be corrected but csplain/cslatex stuff would no longer be usable in
4. to replace the relevant files by old version (Feb. 2000): that would
mean that the license violation would be corrected but
pdfcsplain/pdfcslatex would not work properly.
5. to replace relevant files by newer version (Feb 2005): that would mean
that the license violation would be corrected and all cstex stuff would
work properly in teTeX 3.0 environment.
We have had to send five emails to Thomas until he decided to do
something else than 1. He decided on 4. Of course, we would be more
happy if he decided to do 5 (it would be no extra work for him!), but
given our current relationship, that would be too much to expect.

This "dead teTeX" lives happily in many Linux distributions as the current
and latest TeX software. Unfortunately, throught this "dead teTeX", a
patch that violates csplain author's copyright got into hundreds of Linux
(and other Unix) distributions. This was the main reason why I asked for
the problem to be corrected.

This is not _my bug_ in teTeX, this bug is a consequence of our bad
communication (i.e. communnication between T.E. and P.O.). I will try to
show here what I mean by a better communication:
* T.E. (March 2004): Petr, we plan to use only one TeX engine (pdfetex)
for all formats. What should we do in CSTeX?
* P.O. (March 2004): discussion about the best macrocode to fix this on
* P.O. (April 2004): Thomas, I am sending you a new version of CSTeX files
which solves the problem of shared TeX engine for different formats.
Of course, the main teTeX developer is not obliged to inform his
co-workers about his plans. Here is what really happened:
* Bug report from a user to P.O. (Feb. 2005): pdfcsplain does not work
in new teTeX distribution.
* P.O. (Feb. 2005): Oh my, there is shared TeX engine (pdfetex) for
different formats. I didn't know about it. Discussion about the
best macrocode to fix this on cstex@ list.
* P.O. to T.E.: (March 3 2005): Thomas, I am sending a new version of
CSTeX files which solves the problem of shared TeX engine for different
What went on at this point? I believe that the ideal communication betwen
co-workers would follow like this:
* T.E. to P.O. (Mar. 2005): thanks for new wersion, but I released
teTeX tree tetex-texmf-3.0.tar.gz one month ago. There is old
version of CSTeX here. I don't plan to do any changes in file
tetex-texmf-3.0.tar.gz and this file will be for many months the
official source of TeX software for hudreds of Linux distributions.
* P.O. to T.E. (Mar. 2005): please, upgrade CSTeX files not only in the
development tree but also in tetex-texmf-3.0.tar.gz. The old version
of CSTeX does not work in the environment with shared TeX engine
(problems with pdfcsplain/pdfcslatex).
* T.E. to P.O. (Mar. 2005): done, tetex-texmf-3.0a.tar.gz is released.
* P.O. to T.E. (Mar. 2005): Thank you.
Unfortunately, this communication has never happened. What happened was
this: P.O. was never informed that the source for Linux distributions was
not upgraded with CSTeX files from March 3 2005. The end users of CSTeX
from Linux distributions are out of luck, because due to communication
problems between P.O. and T.E. the software they need does not work.
