"""Translation layer between pyproject config and setuptools distribution and
metadata objects.

The distribution and metadata objects are modeled after (an old version of)
core metadata, therefore configs in the format specified for ``pyproject.toml``
need to be processed before being applied.

The following seems to be defined outside of `pyproject.toml`:

`{field} = {value!r}`

According to the spec (see the link below), however, setuptools CANNOT
    consider this value unless `{field}` is listed as `dynamic`.

https://packaging.python.org/en/latest/specifications/declaring-project-metadata/

For the time being, `setuptools` will still consider the given value (as a
    **transitional** measure), but please note that future releases of setuptools will
    follow strictly the standard.

To prevent this warning, you can list `{field}` under `dynamic` or alternatively
    remove the `[project]` table from your file and rely entirely on other means of
    configuration.
