 During Maven initialization, Maven tweaks default root logging level to match CLI verbosity choice. Since such feature isn't available
 in SLF4J API, logging implementation specific extensions need to be added into Maven to support these CLI options: see

        return False
    content_path.write_text(new_content, encoding="utf-8")
    logging.info(f"Updated {content_path}")
    return True


def main() -> None:
    logging.basicConfig(level=logging.INFO)
    settings = Settings()
    logging.info(f"Using config: {settings.model_dump_json()}")
    g = Github(settings.pr_token.get_secret_value())
    repo = g.get_repo(settings.github_repository)

## 掛載一個 **FastAPI** 應用程式 { #mounting-a-fastapi-application }

「掛載」是指在某個特定路徑下加入一個完全「獨立」的應用程式，之後該應用程式會負責處理該路徑底下的一切，使用該子應用程式中宣告的*路徑操作（path operation）*。

### 頂層應用程式 { #top-level-application }

先建立主（頂層）**FastAPI** 應用程式以及它的*路徑操作*：

{* ../../docs_src/sub_applications/tutorial001_py310.py hl[3, 6:8] *}

### 子應用程式 { #sub-application }

接著，建立你的子應用程式及其*路徑操作*。
