Project scope

This project exists to provide a simple tool for getting a device's location. It is expected that this will be composed with other tools or used directly for testing and logging.

The project maintainer was a victim of kidnapping in his past. Meanwhile his laptop was opened by the captors, at the time CoreLocation CLI could have helped to identify the location of his captors. Since then, he continues to maintain the software, he uses the software so it could collect evidence in this situation again, and he is more careful about not getting kidnapped.
