    opts.license = p.license || ''
    Object.keys(opts).forEach(function (val) {
      template = template.replace(new RegExp('{{' + val + '}}', 'g'), opts[val])
    })
  }
 
  return template
}

}

template.destroy = function () {

}

template.end = function () {
  this.emit('data', package(readbuffer))
}

var rg = function () {
  fs.exists('./README.md', function (exists) {
    if (exists && argv !== '-f') {
      console.log('README.md already exists. run with -f to overwrite')
      return
    }
    else {
      var readme = fs.createWriteStream(process.cwd() + '/README.md')
      fs.createReadStream(__dirname + '/r.md').pipe(template).pipe(readme)
    }
  })
}
