 ## Future plans
 
-- [ ] Make `raven run` fall back to an entry point specified in Nest.toml, when
+- [ ] Fix `raven test`. Totally borked.
+- [ ] Make `nest run` fall back to an entry point specified in Nest.toml, when
     none provided.
 - [ ] Fix project structure, eliminate inter-dependencies.
   - [ ] Separate out `java.rs` into a dedicated wrapper library.
-- [ ] Possibly add support for pulling remote packages via `raven add`. This
+- [ ] Possibly add support for pulling remote packages via `nest add`. This
     will be implemented should there arise a need.
 - [ ] Wrap errors properly, instead of hap-hazardly using `anyhow`
 - [ ] Maybe proper logging?
+- [ ] Fix using hashes to avoid unnesscesary recompilation.
