## What it is
Boot is a build tooling framework for Clojure that treats builds as programs written in Clojure rather than declarative configuration. It provides a runtime environment with composable task pipelines, classpath isolation via pods, a managed immutable filesystem tree, and ad-hoc Clojure script evaluation.

## Use cases
- build clojure projects with a programmable build tool
- write build scripts in clojure instead of a declarative dsl
- compose build pipelines from reusable tasks
- run clojure scripts without a project context
- manage complex builds with asset pipelines and multiple artifacts
- isolate classloaders and run separate clojure runtimes in one jvm

## When to choose
- you want a turing-complete build specification written in Clojure
- your build process is complex with many integrations and multiple artifacts
- you prefer composing middleware-style tasks over editing a global config map
- you want to evaluate ad-hoc Clojure scripts with dynamically added Maven dependencies

## When to avoid
- you are starting a new Clojure project and want the community-standard tools.deps CLI
- you prefer declarative build configuration like Leiningen's project.clj
- you need a build tool with active recent development and a large current ecosystem
- you are not working on the JVM or with Clojure

## Facets
- artifact type: cli-tool
- maturity: maintenance

- domain: developer-tools, programming-languages
- platform: jvm, windows, cli
- tags: clojure, build-pipelines, jvm, repl-driven, task-composition, automation, linux, macos
