works well (obiously there are some other features I will introduce in future 
releases), and I think it could be moved out from playground, into the stable 
kde-edu branch. I'm writing this email for three reasons: the first is that I 
don't know how to move Kartesio into the stable branch (maybe it needs your 
approval?). The second one is to tell that anyone's contribute in developing 
this software will be obiously appreciated. The third is just to let you know 
this program: if you work in a lab, you may need to calculate best fit curves, 
and Kartesio could interest you. I, for example, study chemistry and I already 
used Kartesio for some laboratory reports.I would love to hear your opinions 
about it.

Hi Luca, I spotted some problems with the used licenses in Kartesio. In all 
the files I looked yet, the GPL 3+ license is used. Yet, the KDE license policy 
[1] says that all code must be licensed such that it is compatible to GPL 2+, 
Unfortunately this is not the case for GPL 3+.

A possible solution would be to re-license the code to "GPL version 2 or 
version 3 or any later version". If you want to re-license the code, AFAIK the 
sysadmins would like to archive information about this re-licensing procedure 
[2].

Greetings,
Andreas
