Cli is a port of [http://docs.fuelphp.com/classes/cli.html](Fuel's Cli class).
Please refer to Fuel's docs for usage instructions. The only API difference from Fuel's
implementation is the use of \Exception instead of FuelException. You will need to call
Cli::_init();
before using Cli's static methods.
You may use a require for Cli.php or use composer to install.
