The **resourceful‑base‑engine** package provides a lightweight, reusable base class for building “engine” adapters used by the Resourceful ORM (e.g., REST, S3, SimpleDB). It implements common CRUD logic—such as an `update` method that merges data and creates records when missing—so that developers only need to supply storage‑specific `get` and `put` functions when creating new engines. This is aimed at Node.js developers extending Resourceful with custom data back‑ends.
