# 5.7.项目网站

每个 Port 应指向提供更多软件信息的网站。

如果可能的话，这应该是由软件开发者维护的官方项目网站。

```makefile
WWW=		https://ffmpeg.org/
```

但它也可以是源代码仓库中的目录或资源：

```makefile
WWW=		https://sourceforge.net/projects/mpd/
```

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

如果相同的内容可以通过 HTTP 和 HTTPS 访问，应使用以 `https://` 开头的 URL。如果 URI 是网站或目录的根目录，则必须以斜杠结尾。

这些信息以前放在 **pkg-descr** 文件的最后一行。现在已将其移至 **Makefile** 以便于维护和处理。**pkg-descr** 文件末尾的 `WWW:` 行已被弃用。

# Agent Instructions
This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.

## 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/5.7.-xiang-mu-wang-zhan.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.
