# 5.12.man 手册

如果 Port 将其 man 树放置在 `PREFIX` 以外的地方，请使用 `MANDIRS` 来指定这些目录。请注意，手册页对应的文件必须与其他文件一起放置在 **pkg-plist** 中。`MANDIRS` 的目的是启用手册页的自动压缩，因此文件名会以 **.gz** 结尾。

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://book.bsdcn.org/port/di-5-zhang-pei-zhi-makefile/5.12.man-shou-ce.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
