# 重新打包

解压之后，还可以再打包，比如上面的例子中，我们用下面的命令将解压的重新打包：

```
 $ pkgutil --flatten ~/Desktop/MSUpdater ~/Desktop/MSUpdater.pkg
```

这样我们又在\~/Desktop上建立了一个新的安装包MSUpdater.pkg。

在实际使用中，我们往往会遇到一种情形，先使用开发商的安装包安装一遍，然后根据自己的特定需要，只将所需部分提取出来，在做好本地化工作之后，再将其打包为只适用于自己环境的安装包，这样可以省去本地化的工作。特别是在企业环境中，可能会碰到这样的情况，便于企业应用的部署和支持。这也是一种再打包的应用场景。
