var recursiveReaddirSync = function (topDir) {
  function readdir (dir) {
    fs.readdirSync(dir).filter(function (pth) {
      return !/^\./.test(pth)
    }).forEach(function (pth) {
      pth = path.join(dir, pth)
      if (fs.lstatSync(pth).isDirectory()) readdir(pth)
      else files.push(pth)
    })
