Packaging Legacy

Packaging-legacy is a Python library, currently at version 23.0.post0, that provides support for 'legacy' Python packaging functionality. It restores features, primarily related to version parsing, that were removed from the official `packaging` library. Its main utility is the `packaging_legacy.version.parse` function, which can handle version strings that the modern `packaging` library would deem invalid. The library has an infrequent release cadence, with only two releases to date, both in late 2023.
