Common Public License
Antmod is released and distributed under the Common Public License.
This means that you can use Antmod freely in commercial and non-commercial projects. You are required to make changes that you make available to the Antmod community, but besides that there are not many restrictions. Also, the way you make your changes available is up to you, as long as you inform us through one of the mailing lists.
The Common Public License is the best choice to give you the freedom you need and the Antmod community the possibility to grow and benefit from the changes others make and invent.
