This convention avoids the need to hard-code a package's import path in its
own source code, making it easier to move the code from one location to another.

이 환경변수들은 오직 **텍스트 문자열**로만 처리할 수 있습니다. 텍스트 문자열은 파이썬 외부에 있으며 다른 프로그램 및 나머지 시스템(Linux, Windows, macOS 등 다른 운영 체제)과 호환되어야 합니다.

* **WebSocket** support.
* In-process background tasks.
* Startup and shutdown events.
* Test client built on HTTPX.
