Things to think about:
- Import Built-Using sources
- all / only referenced
- Remove old packages:
- by-source: remove source X_v, if no X exists upstream
- by-version: remove source X_v, if no X_v exists upstream
(X denotes package name, v version, X_v package at a specific version)
- Import all or only newest?
- Expire binary packages?
