This example project shows how SBOMs can be added to Python wheels alongside bundled shared libraries. Frequently shared libraries are taken from the operating systems' package manager, especially when being built in a particular build environment like cibuildwheel.
The file Pillow-10.0.0-cp312-cp312-manylinux_2_28_x86_64.whl
contains an SBOM file Pillow-10.0.0.dist-info/auditwheel.cdx.json.
This file is annotated in metadata (Pillow-10.0.0.dist-info/METADATA)
with the Sbom-File field.
