## What it is
Cement is an advanced application framework for Python with a primary focus on building command line interfaces, ranging from single-file scripts to complex multi-tier applications. It provides a handler/interface system with built-in support for configuration parsing, argument handling, logging, plugins, output rendering, caching, and controllers with sub-commands.

## Use cases
- build a command line tool in python
- structure a multi-command cli application with subcommands
- add plugin support to a python cli app
- parse config files and merge them with command line arguments
- add logging and output rendering to a backend python application
- rapidly scaffold a python cli framework with zero dependencies

## When to choose
- you need a full-featured, battle-tested framework for complex CLI applications
- you want extensibility via handlers, interfaces, hooks, and plugins
- you want zero external dependencies in the core
- you need config, logging, argument parsing, and output handled in one framework

## When to avoid
- you only need a simple argument parser (use argparse or click instead)
- you are building a web application or GUI rather than a CLI/backend tool
- you prefer a minimal micro-framework with less structure
- you need support for Python versions older than 3.10
