oTranCe is an free and open source software project under GNU LESSER GENERAL PUBLIC LICENSE in version 2.1.
Why do we use GPLv2 instead of the present version 3? Well, we think that in some points, GPLv3 is a bit too restricitive. It should be possible to use oTranCe without any unneccessary obstacles. In our opinion, GPL version 2 garantees the free usage a better way.
