# 我該如何使用 frontespizio 套件？

該 [`frontespizio` 套件](http://www.ctan.org/tex-archive/macros/latex/contrib/frontespizio) 會以適合義大利大學論文的樣式排版封面頁。它會將封面頁另存為一個獨立的 PDF，之後再將其包含回主專案中。這表示在建置封面頁時需要一個特殊的編譯步驟。若要在 Overleaf 上達成這一點，你可以使用 `\write18` 來開始編譯，如下所示：

```latex
\begin{frontespizio}
\Istituzione{Politecnico di Torino}
% ... 你的其他資訊放在這裡
\end{frontespizio}
\IfFileExists{\jobname-frn.pdf}{}{%
\immediate\write18{pdflatex \jobname-frn}}
```

如果封面頁編譯失敗，你可以使用 listings 套件，然後放入

```latex
\lstinputlisting{output-frn.log}
```

在上面的程式碼之後，將日誌檔匯入你的主專案中，這樣你就可以閱讀它並找出問題所在。

請注意，如果你使用的是 LuaLaTeX 編譯器，你需要加入

```latex
\usepackage{shellesc}
```

到你的前言區中，這樣才能運作，並使 `\write18` 或 `\ShellEsc` 命令 [可供 LuaLaTeX 使用](https://tex.stackexchange.com/a/366200/226).

## 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://overleaf-pro.ayaka.space/latex/zh-tw/wen-yu-da/39-how-do-i-use-the-frontespizio-package.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.
