Er... are you sure that you understand each other? It seems to me
that you, Werner, are saying that you’re not going to distribute the
files under their original names, and will just use a temporary solution
until the changes are propagated to the distributions; while Frank is
saying that since you plan to distribute the files you should stick to
the policy of changing their names.
