## What it is
Blueprint is a Python CLI tool that reverse-engineers server configuration by inspecting package managers, config file changes, and source-installed software. It stores blueprints in Git and can export them as POSIX shell scripts, Puppet modules, Chef cookbooks, or CFEngine 3 sketches.

## Use cases
- capture the configuration of an existing server as reusable code
- convert a hand-configured server into a Puppet module or Chef cookbook
- diff two servers to find configuration drift
- clone a server's setup onto a new machine
- archive packages and source-installed software from a server

## When to choose
- you have a legacy hand-configured Debian or RPM-based Linux server you want to codify
- you need a one-off snapshot of server state without adopting a full config management workflow
- you want to migrate imperative server changes into Puppet, Chef, or CFEngine

## When to avoid
- you need an actively maintained tool - the last release was 2018 and it targets Python 2.6-era systems
- you run non-Debian/non-RPM systems like Alpine, Arch, or macOS
- you want modern infrastructure-as-code with idempotent, testable modules - use Ansible, Terraform, or Pulumi instead
