The wheels are generated via cibuildwheel, a tool provided by the Python Packaging Authority (PyPA) [0]. The tool leverages toolchains within containers maintained by PyPA [1] to generate wheels that are runnable on hosts that meet the requirements defined by the tag [2]. The script currently creates X86_64 and AArch64 CPython 3.9-3.12 wheels for glibc and musl libc based systems. These defaults can be overridden via CIBW_* environment variables [3].
