    console.log('Hey give me some help here');
  })

  .on('--file', function (option, value) {
    // if no files passed show a message
    if (!value) {
      console.log('Usage: --file <file1.js file2.js>');

    // simple check if the value passed to --file are js files
    } else if (!/\.js$/.test(value)) {
      console.log('Only .js files can be passed using the --file option!');
    }
