Re: [PATCH 3 of 4] purge local packages no longer in repo

When tracking a bleeding edge repository like Fedora rawhide, existing packages in a repo will be updated on a regular basis, removing the older versions. This leaves large numbers of obsolete packages in the locally synced directory which are never cleaned up. This patch adds a --delete argument which instructs reposync to unlink any packages in the local directory which are no longer present in the remote repository.
