Crrcsim is a model-airplane flight simulation program. Using it, you
can learn how to fly model aircraft, test new aircraft designs, and
improve your skills by practicing on your computer.

The flight model is very realistic. The flight model parameters are
calculated based on a 3D representation of the aircraft. Stalls are
properly modelled as well. Model control is possible with your own rc
transmitter, or any input device such as joystick, mouse, keyboard.

The package pkglints, builds and runs fine, but has a few minor todos
left.
