//TODO: add USB, REPL to description once they're operational
//| .. currentmodule:: supervisor
//|
//| :class:`Runtime` --- Supervisor Runtime information
//| ----------------------------------------------------
//|
//| Get current status of runtime objects.
//|
//| Usage::
//|
//|    import supervisor
//|    if supervisor.runtime.serial_connected:
//|        print("Hello World!")
//|

//| .. class:: Runtime()
//|
//|     You cannot create an instance of `supervisor.Runtime`.
//|     Use `supervisor.runtime` to access the sole instance available.
//|

//|     .. attribute:: runtime.serial_connected
//|
//|         Returns the USB serial communication status (read-only).
//|
//|     .. note::
//|
//|         SAMD: Will return ``True`` if the USB serial connection
//|         has been established at any point.  Will not reset if
//|         USB is disconnected but power remains (e.g. battery connected)
//|
//|         Feather52 (nRF52832): Currently returns ``True`` regardless
//|         of USB connection status.
