"""Demote packages to proposed pocket.
This is useful in the case where a package fails to build or is otherwise
broken, but we don't want to remove it from the archive permanently and
would be happy to take a fix by way of a sync from Debian or similar. In
cases where the package comes from Debian, make sure that any demotion to
proposed is accompanied by a Debian bug report.
This is analogous to removing a package from Debian testing.
