  { name="Pierre-François Duc", email="pierre-francois.duc@rl-institut.de" },
]
description = "A package that contains various constraint facades to be used with oemof-tabular"
requires-python = ">=3.9"
classifiers = [
    "Programming Language :: Python :: 3",
    "License :: OSI Approved :: MIT License",
    "Operating System :: OS Independent",

[build-system]
requires = ["setuptools>=61"]
build-backend = "setuptools.build_meta"
