delete_orphan_files.php [options]
Deletes all files and their File entries where there is no link to a
Notice entry. Good for cleaning up after user deletion or so where the
attached files weren't removed as well.
-y --yes do not wait for confirmation
Will print '.' for each deleted File entry and 'x' if it also had a locally stored file.
