The FU4D package is available for free to all 4D developers worldwide. There is no development or deployment costs or licenses of any kind with this software package.

You didn't actually expect us to charge for this, did you? Seriously, it took us only a few hours to put these extensions together. We can't reasonably charge for such a small effort on our part, especially considering how much good these tools can do for the 4D developer community.

Enjoy!
