 ## PHPUnit
 
 This koans project uses Sebastian Bergmann's wonderful [PHPUnit](https://phpunit.de/) command ([source code](https://github.com/sebastianbergmann/phpunit)). The PHAR binary is included in this project for convenience and to lower the setup curve. It has been renamed from `phpunit` to `contemplate_koans` to fit with the theme of this project. See `LICENSE_PHPUnit` for the relevant license information.
