Custom Zig PyPI packaging script
# This script builds a custom Zig distribution into a Python wheel.
#
# The "custom" distribution refers to any directory resulting from
# zig-bootstrap that doesn't make into public nightly or stable releases.
# The existing ziglang/zig-pypi doesn't work with such cases, hence
# this script. It still makes use of a large portion of make_wheels.py,
# so should be put into the same directory in order to function.
#
# This script is derived from make_wheels.py from zig-pypi (commit
# 5b30070bc), and thus distributed under the same license (MIT/Expat).
