-*Toast* is a tool for doing work in containers. You define tasks in a YAML file called a *toastfile*, and Toast runs them in a containerized environment based on a Docker image of your choosing. What constitutes a "task" is up to you: tasks can install system packages, build an application, run a test suite, or even serve web pages. Tasks can depend on other tasks, so Toast can be understood as a high-level containerized build system.
