packaging
=========

.. start-intro

Reusable core utilities for various Python Packaging
`interoperability specifications <https://packaging.python.org/specifications/>`_.

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, metadata, lockfiles, utilities.

Documentation
-------------

The `documentation`_ provides information and the API for the following:

- Version Handling
- Specifiers
- Markers
- Licenses
- Requirements
- Metadata
- Tags
- Lockfiles (pylock)
- Direct URL helpers
- Dependency groups
- Errors
- Utilities

Installation
------------

Use ``pip`` to install these utilities::

    pip install packaging

The ``packaging`` library uses calendar-based versioning (``YY.N``).
