"""
The molten web framework is automatically traced by ``ddtrace``::

    import ddtrace.auto
    from molten import App, Route

    def hello(name: str, age: int) -> str:
        return f'Hello {age} year old named {name}!'
    app = App(routes=[Route('/hello/{name}/{age}', hello)])


You may also enable molten tracing automatically via ``ddtrace-run``::

    ddtrace-run python app.py
