# Maintainer: Hasan Çatalgöl <hasancatalgol at gmail.com>
# Package: python-dlt
#
# dlt (data load tool) is a Python library/CLI for loading data into
# warehouses/lakes. We build from the PyPI sdist and install the wheel.
#
# Notes:
# - Upstream supports many extras (athena/bigquery/duckdb/etc). We
#   surface major ones via optdepends so users can choose engines.
# - Core package targets Python 3.9–3.14 (per upstream metadata), but
#   we only depend on 'python' since Arch ships a single Python.  See:
#   https://pypi.org/project/dlt/ (Provides-Extra, Python reqs)
