## What it is
PyBuilder is a build automation tool written in pure Python, primarily for Python projects. It uses dependency-based programming with a plugin mechanism to create build life cycles similar to Maven or Gradle, handling testing, coverage, code analysis, and packaging.

## Use cases
- automate building and packaging a python project
- run unit tests and coverage on every build
- generate setup.py and distutils packaging from a build descriptor
- scaffold a new python project with a standard directory layout
- integrate flake8 or pylint checks into the build lifecycle
- replace a pile of ad-hoc build scripts with one tool

## When to choose
- you want a Maven/Gradle-style build lifecycle for a Python project
- you prefer writing build logic in Python itself
- you want testing, coverage, linting, and packaging unified in one command

## When to avoid
- your project already works well with setuptools, hatch, or poetry
- you need a build tool with a large ecosystem and community
- you only need simple packaging without build lifecycle management

## Facets
