The code is divided in three crates: - plume-common, for the ActivityPub module, and some common utils - plume-models, for the models and database-related code - plume, the app itself This new organization will allow to test it more easily, but also to create other tools that only reuse a little part of the code (for instance a Wordpress import tool, that would just use the plume-models crate)
