This library provides utilities that implement the interoperability specifications which have clearly one correct behaviour (eg: :pep:`440`) or benefit greatly from having a single shared implementation (eg: :pep:`425`). .. end-intro The ``packaging`` project includes the following: version handling, specifiers, markers, requirements, tags, utilities. Documentation ------------- The `documentation`_ provides information and the API for the following: - Version Handling - Specifiers - Markers - Requirements - Tags - Utilities Installation ------------ Use ``pip`` to install these utilities:: pip install packaging Discussion ---------- If you run into bugs, you can file them in our `issue tracker`_. You can also join ``#pypa`` on Freenode to ask questions or get involved. .. _`documentation`: https://packaging.pypa.io/ .. _`issue tracker`: https://github.com/pypa/packaging/issues Code of Conduct --------------- Everyone interacting in the packaging project's codebases, issue trackers, chat rooms, and mailing lists is expected to follow the `PSF Code of Conduct`_. .. _PSF Code of Conduct: https://github.com/pypa/.github/blob/main/CODE_OF_CONDUCT.md Contributing ------------ The ``CONTRIBUTING.rst`` file outlines how to contribute to this project as well as how to report a potential security issue.
