fs.readFile('package.json', 'utf8', (err, data) => {
  const distPackage = JSON.parse(data)
  distPackage['scripts'] = DIST_SCRIPTS
  delete distPackage['devDependencies']

  fs.writeFile('dist/package.json', JSON.stringify(distPackage, null, '\t'), 'utf8', () => {
    console.info('Generated distribution-friendly package.json at dist/package.json')
