# 5.6.一句话说明（COMMENT）

说明是显示在 `pkg info` 中的 Port 的一行描述。在编写说明时，请遵循以下规则：

1. `COMMENT` 字符串不应超过 70 个字符。
2. 不要包含软件的包名或版本号。
3. 说明应以大写字母开头，且末尾不加句号。
4. 不要以不定冠词（即 A 或 An）开头。
5. Apache、JavaScript 或 Perl 等名称应使用大写字母。
6. 列表中的单词应使用串联逗号：`green, red, and blue`。
7. 检查拼写错误。

示例：

```makefile
COMMENT=	Cat chasing a mouse all over the screen
```

`COMMENT` 变量紧跟在 **Makefile** 中的 `MAINTAINER` 变量后面。

## 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/porters-handbook/di-5-zhang-pei-zhi-makefile/5.6.-yi-ju-hua-shuo-ming-comment.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.
