### demo

画个图验证一下

```bash
# 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 :)

```bash
+-------+     +-------+     +-------+
| page1 |     | page1 |     | page1 |
+-------+     +-------+     +-------+
|       |     |       |     |       |
| page2 | --> | page2 | <-- | page2 |
+-------+     +-------+     +-------+
|       |     |       |     |       |
| page3 |  +> | page3 |     | page3 |
+-------+  |  +-------+     +-------+
|       |  |  |       |     |       |
| page4 | -+  | page4 | <-- | page4 |
+-------+     +-------+     +-------+
| page5 |     | page5 |     | page5 |
+-------+     +-------+     +-------+
