* busca el subpaquete `routers` (el directorio en `app/routers/`)...
* y de él, importa el submódulo `items` (el archivo en `app/routers/items.py`) y `users` (el archivo en `app/routers/users.py`)...

El módulo `items` tendrá una variable `router` (`items.router`). Este es el mismo que creamos en el archivo `app/routers/items.py`, es un objeto `APIRouter`.

Y luego hacemos lo mismo para el módulo `users`.
