# This package buildrequires flit_core to build the wheel, but flit_core requires tomli.
# To bootstrap, we copy the files to appropriate locations manually and create a minimal dist-info metadata.
# Note that as a pure Python package, the wheel contains no pre-built binary stuff.
# When bootstrap is enabled, we don't run tests either, just an import check.

# RHEL 8's pytest is too old and does not support the tmp_path filter.

# RHEL 8's old dateutil is missing parser.isoparse.
# This upstream change removes that dependency entirely.
