# Note on versioned build-dependencies: upstream marks lower supported versioned-dependencies
# using equality (e.g. "mpi4py ==3.0.3"), meaning the lower supported version is forced in upstream pypi builds.
# We generally want to build using higher versions (the most recent available and packaged in unstable)
# Upstream suggests switching off version checking in that case, by setting H5PY_SETUP_REQUIRES=0.
# However rather than applying H5PY_SETUP_REQUIRES=0, in Debian we maintain minimal version checks
# by patching setup.py to inequalities where needed (e.g. "mpi4py >=3.0.3")
