> Hi Buildroot,
>      
> Thought you might be interested in mircopython a minimal python 3
> implementation. It's designed for micro controllers but is also well suited
> to other general purpose embedded CPUs.

>      
> Changes since v1:
> - Add dependency on host-pkgconf.
> - Use $(TARGET_MAKE_ENV) in make invocation for micropython
>    (micropython-lib doesn't need it because it doesn't use anything setup by
>    it).
> - Override PREFIX to install to /usr/bin instead of /usr/local/bin
> - Update/add some comments.
>      
> Changes since v2:
> - Use $(TARGET_MAKE_ENV) in micropython-lib for consistency
> - Update LICENSE for micropython-lib (thanks to Vincent for the shell
>    snippet that saved me having to check them manually).
> - Add patch to take the version number from the package instead of from the
>    buildroot git repository.
