buildsummary
自动生成gitbook的SUMMARY.md文件，会按照目录结构来生成逐级的列表。 比如你的文件结构是这样的
$ tree ..├── topic1│ ├── artic1.md│ └── topic1-1│ └── artic1-1.md└── topic2 └── artic2.md那么生成SUMMARY.md文件内容是
* topic2 * [artic2](./topic2/artic2.md)* topic1 * [artic1](./topic1/artic1.md) * topic1-1 * [article1-1](./topic1/topic1-1/artic1-1.md)
