# 5.6.一句话说明（COMMENT）

评论是显示在 `pkg info` 中的 Port 的一行描述。在编写评论时，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. 评论应以大写字母开头，且末尾不加句号。
4. 不要以不定冠词（如 A 或 An）开头。
5. 对于名称，如 Apache、JavaScript 或 Perl，要使用大写字母。
6. 列表中的单词应使用串联逗号：例如 `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。
