画个图验证一下

# cat page1.txt
[page1||
page2||
page3||
page4||
page5||]{basename:parent}

[page1||
page2||
page3||
page4||
page5||]{basename:ram}

[page1||
page2||
page3||
page4||
page5||]{basename:child}

[child.1]{flow: west} -> [ram.1]
[parent.1]{flow: east} -> [ram.1]

[child.3]{flow:west} -> [ram.3]
[parent.3]{flow:east} -> [ram.2]

输出结果,看上去还不错 🙂
