## What it is
A command line utility that emulates Heroku build and runtime tasks inside containers, running buildpacks and parsing Procfiles. It is designed for platform authors building Heroku-compatible PaaS systems like Dokku.

## Use cases
- run heroku buildpacks inside docker containers
- parse and execute procfile commands in a container
- build a self-hosted paas compatible with heroku apps
- export and import heroku slugs
- test applications using heroku buildpacks
- emulate heroku runtime environment locally

## When to choose
- building a heroku-compatible platform like dokku
- deploying apps that rely on heroku buildpacks in your own containers
- you need heroku build and runtime behavior without heroku

## When to avoid
- deploying directly to heroku itself
- you need a general-purpose docker build tool unrelated to heroku
- running on busybox or minimal shells without bash 4+

## Facets
