I found 3 interesting things in the licenses. 1. Most is licensed under LGPL.
2. It has a restriction but maybe it isnĀ“t a problem: RestrictionsYou may use this software on a computer system only if you own the system or have the permission of the owner.
3. PS2Grids license is non free. Maybe some one has to help me there, if I miss a file.
Momentary I use the materbranch on the latest code. I will uplad the code to Gitorious. In a rather unmodified state.
