Everything happens automagically with overridden "sdist" from
sdist_upip.py.

The idea of this module is to convert binary data to a Python bytes
object, and put it into the dictionary, indexed by the resource name.
This conversion is done using ``tools/mpy_bin2res.py`` script from
the MicroPython distribution.
This conversion is done automatically using overridden ``sdist`` command
described in the previous section.
Let's trace the complete process using the following example. Suppose
your application has the following structure::

You can develop and debug using the `MicroPython Unix port` as usual.

need to run following command, with ``my_app/`` being the current

This will create a Python resource module named ``R.py``, based on the
files declared in ``MANIFEST`` or ``MANIFEST.in`` files (any non-``.py``
file will be considered a resource and added to ``R.py``) - before
proceeding with the normal packaging steps.
This will produce a Python resource module named ``R.py``. Afterwards,
you package the project for distribution as usual (using ``setup.py sdist``).
Prepared like this, your application will work both when deployed to
filesystem and as frozen bytecode.
If you would like to debug ``R.py`` creation, you can run::
python3 setup.py sdist --manifest-only
Alternatively, you can use tools/mpy_bin2res.py script from the
MicroPython distribution, in which can you will need to pass paths
to all resource files::
