It provides a complete set of utilities for working with Python package metadata according to established interoperability specifications such as PEP 440 (version handling) and PEP 425 (platform tags).\n\nThe package implements version parsing and comparison, version specifiers (e.g., '>=1.0'), environment markers for conditional dependencies, requirement parsing, platform tag handling, and general packaging utilities. It is intended for projects that still need to handle legacy version formats or require a stable snapshot of packaging functionality from an earlier point in time. The single runtime dependency is pyparsing, and the package supports Python 3.6 through 3.10 on CPython and PyPy.","worth_installing":"Yes, if you specifically need LegacyVersion support or require a stable snapshot of packaging utilities. The package is production-stable, permissively licensed, and has no known vulnerabilities. However, it is dormant\u2014no updates since late 2022\u2014so do not expect active maintenance or bug fixes. Install only if you have a concrete reason to use this fork rather than the current upstream packaging library."},"id":"packvers","links":{"html":"https://skillfed.io/packages/packvers","md":"https://skillfed.io/packages/packvers.md","pypi":"https://pypi.org/project/packvers/"},"maintenance":{"status":"dormant"},"meta":{"latest_release":"2022-12-22","license_spdx":null,"license_treatment":"permissive","name":"packvers","python_support":"supports_current","summary":"Core utilities for Python packages.
