# HACK:
# Upstream uses a very unconventional structure to organize the packages, and we have to coax the
# existing infrastructure to work with it.
# See https://github.com/RapidAI/RapidOCR/blob/02829ef986bc2a5c4f33e9c45c9267bcf2d07a1d/.github/workflows/gen_whl_to_pypi_rapidocr_ort.yml#L80-L92
# for the "intended" way of building this package.
# The setup.py supplied by upstream tries to determine the current version by
# fetching the latest version of the package from PyPI, and then bumping the version number.
# This is not allowed in the Nix build environment as we do not have internet access,
# hence we patch that out and get the version from the build environment directly.
