# 7.6.USES=guile 和 Flavors

当使用 [`guile:flavors`](https://docs.freebsd.org/en/books/porters-handbook/uses/#uses-guile) 时，Port 会自动填充 `FLAVORS`，其中包含它所支持的 Guile 版本。不过，普通的应用程序通常不应使用这个功能；它主要用于库和扩展，例如 `guile-lib` 或 `guile-cairo`。

`GUILE_FLAVOR` 是可用的（并且必须使用）变量，用于依赖正确版本的、带 flavor 的依赖项，无论该 Port 是否使用了 `flavors` 参数。

## 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-7-zhang-flavors/7.6.guile-he-flavors.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.
