## What it is
Versioneer is a Python tool that manages version strings for setuptools-based projects by deriving them automatically from version-control tags (primarily Git). It eliminates the manual step of updating embedded version numbers during releases.

## Use cases
- automatically derive package version from git tags
- stop manually updating version strings in setup.py
- manage versions for sdists built from git tarballs
- keep python package version in sync with VCS
- set up versioning for a setuptools project

## When to choose
- your Python package is hosted in Git and built with setuptools
- you want tag-driven, zero-maintenance version numbers
- you distribute both VCS checkouts and release tarballs

## When to avoid
- your project doesn't use setuptools
- you prefer modern PEP 621 tooling like setuptools-scm or hatch-vcs
- your VCS is not Git or a supported system

## Facets
- artifact type: library
- maturity: stable
- function: build-tool, version-control, developer-tools
- domain: developer-tools, version-control
- platform: python, cli, cross-platform
- tags: setuptools, versioning, git, packaging, release-automation, automation
