-| `storage`       | library            | Defines a unified interface to use different storage backends (like Geomerge, SQLite, LMDB, etc.)                             |
-| `query-ops`     | library            | Provides a set of operators to physcially execute a query.                                                                    |
-| `plan-runner`   | library and binary | Provides a CLI to run a query plan represnetsion against a given storage backend uisng the operatirs provided by `query-ops`. |
-| `geomerge-demo` | binary             | An example that shows how to write and read to Geomerge (as a storage).                                                       |
