# build_macos_packages.sh
# One stop build of IREE Python packages for MacOS. This presumes that
# dependencies are installed from install_macos_deps.sh. This will build
# for a list of Python versions synchronized with that script and corresponding
# with directory names under:
#   /Library/Frameworks/Python.framework/Versions
#
# MacOS convention is to refer to this as major.minor (i.e. "3.9", "3.10").
# Valid packages:
#   iree-base-runtime
#   iree-base-compiler
