This empty package will, at the time of installation, download the current MicroPython runtime for the micro:bit as bundled with uflash upstream.

The firmware image will be downloaded from https://github.com/ntoll/uflash and saved to /usr/share/firmware-microbit-micropython/firmware.hex

Note that this package will not flash MicroPython onto the micro:bit; that can be done with the uflash utility (package: python3-uflash).
