## What it is
Roswell is a command-line utility that installs, manages, and launches Common Lisp implementations and integrates with Quicklisp. It also provides scripting and binary-building facilities, making it a full-stack environment manager for Common Lisp development.

## Use cases
- install common lisp implementations from the command line
- manage multiple sbcl or ccl versions
- run a lisp repl with ros run
- build standalone executables from lisp scripts
- install and distribute lisp scripts via quicklisp
- set up common lisp in CI pipelines

## When to choose
- you want a simple, git-like CLI to manage Common Lisp environments
- you need reproducible Lisp setup across Linux, macOS, Windows, or CI
- you want to build and share executable Lisp scripts

## When to avoid
- you only need a REPL and already have an implementation installed
- you work with Scheme or other Lisp dialects rather than Common Lisp
- you need a fully stable, non-beta tool with guaranteed feature completeness

## Facets
- artifact type: cli-tool
