Hi,
I'd like to use Dia programme for commercial use. It is a base for Genealogy programme with clip arts made by Tomasz Steifer (
http://steifer.pl/). What are the terms if I'd like to use his programme with yours Dia in it in a commercial use? Well, it will be just me making those family trees, so it won't be some kind of mass production. Still, I'd like to have everything clear.
