Ardix is being relicensed to GPL v3 or later. I have no idea whether you can just do this if you feel like it or if it has any consequences, but i kinda don't really care that much about it. Any changes made after this commit will definitely fall under the GPL though, and considering that only few things are really working yet anyways this is good enough for me.
