Mikeal Rogers大神曾经提供了一个CouchDB同步工具replicate。但是它是全量同步的，且是依次同步的。但是在某些情况下，我需要快速同步我所知道的几个模块到我的本地来，这就是本模块sync_package诞生的原因。
- 快速同步指定模块
- 自动同步依赖模块
npm install sync_package -g
这里取巧了一下，利用了npm自身的配置方案。
npm config set remote_registry http://isaacs.iriscouch.com/registry/
npm config set remote_registry {remote_registry}
npm config set local_registry {local_registry}
// 因为本地仓库的写入权限问题，所以记得写上口令
npm config set local_registry http://username:password@ip/registry/
注意：请以/结尾。
在配置了本地和远程NPM仓库地址之后，调用同步十分简单：
sync_package sync_package
sync_package express
sync_package express -D // 不同步依赖
sync_package connect express // 同时同步多个模块
事实上，这个模块可以同步任意两个CouchDB数据的文档。
