Synchrotron syncs package from Debian into the appropriate suites. E.g. Debian `testing` is synced to `landing`. This syncs source and binary packages. If a package in PureOS had downstream modifications (indicated by a `pureos` in the version number) it is excluded from the sync. Also packages than vanish from Debian are removed if possible.
