## What it is
Flit is a simple Python packaging tool for publishing packages and modules to PyPI. It generates pyproject.toml metadata, builds wheels and sdists, and publishes with minimal configuration.

## Use cases
- publish a python package to pypi
- create pyproject.toml for a module
- build wheels for a simple python package
- install a package locally for development
- simplify python packaging workflow

## When to choose
- you have a single module or simple package to distribute
- you want minimal packaging configuration and fewer mistakes
- you prefer deriving metadata from docstrings and __version__

## When to avoid
- you need complex builds with C extensions or custom build steps
- you need monorepo or multi-package builds with advanced metadata
- you rely on setuptools-specific features or plugins

## Facets
- artifact type: cli-tool
- maturity: active
- function: package-manager, build-tool, cli
- domain: developer-tools, programming-languages
- platform: python, cli, cross-platform
- tags: pypi, packaging, pyproject-toml, wheel, sdist, automation
