The situation I tried to construct was a litte bit more complex to disable all ways out on the one side and making a change to be able to fix it. A lunatic author can make it impossible to get a stable system, most of the time even changes will not help to get a system which is also feasable to be used with interchanged documents from and to new and old systems. With an incompatible change, that is expected to be used otherwise, you have no chance then to follow it - perhaps a bit later and with warnings - otherwise you will not be able to interchange new documents. In an situation, where one package can not be changed but has to be because of some incompatibility between it and a other one, changing could help to archive the goal. > 1.

In my example I constructed, one either could use the old article and old important ( braking all documents using this new feature in article coming from others sides, so a No-No) or making "important" totally useless.

I think any licence with which Debian can ship .cfg-files in the binary packages containing LaTeX, should and would be considered free enough. > 4.

If only shipping the new version and not the old, all 100.000 documents and programms generating such documents could 'easily' (hust) be found and changed, so this would make it hard to interchange documents with people keeping the old versions. The reason to consider name-chaning requirements of _programs_ not harmful (but only as stupid) is that it can be changed in advance. But this is not true for anything part of an iterchangeable interface. > Was my life difficult? No doubt. However, I guess it would be as > difficult as this if listings would be released under GPL. That is true. But while the right to not be tortured by police won't help me against beeing tortued by my neighbor, it is still a worthy freedom to have. > My > diffculties were becaused by the fact that the task of supporting > software in changing world IS difficult, I did not distribute my > system, but if I did, I do not see how LPPL would make my task any > more difficult, -- or how my life would be easier if listings were > distributed under GPL. As said before, if the new license allows things like shipping a .cfg or some other aquivalent of patching, it is IMHO free enough. > LPPL was crafted for LaTeX.

I think if the license would clearly limit it restrictions to areas with anything called LaTeX it might remove even more provisos. ( As in my opinion a licence is thatmuch better, the more usefull things it allows, that where not thought about by the author) Hochachtungsvoll, Bernhard R.
