+WPIcal is licensed with the [GPL v3](https://github.com/wpilibsuite/allwpilib/blob/main/wpical/copying.md) because of the dependency on Ceres and SuiteSparse which are GPL. Contributors agree that their contribution may be relicensed to only the [WPILib BSD license](https://github.com/wpilibsuite/allwpilib/blob/main/LICENSE.md) should the dependency on GPL code be removed in the future.
