  Caravela — a schema-driven, composable full-stack framework for Phoenix.

  **Declare your domain. Sail with the generated code.**

  Start with `use Caravela.Domain` in a module under `lib/<app>/domains/`
  to declare entities, fields, and relations. Then run
  `mix caravela.gen.schema <Module>` to generate Ecto schemas and a
  migration. See `Caravela.Domain` for the DSL reference.
