Inspired by the ruby koans.
To run the koans use the koans executable with the command
escript koans. This will compile your code and provide the next failing test in the suite to pass.
To run the development tests with substituted answers from answers.config use the command
escript koans test.
To show a hint for the current koan, use
escript koans hint.
See the installation guide. Be sure to install version 17 which includes the much anticipated map feature!
