lifthrasiir / make_wheels_from_dir.py

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).
