File::Util::Interface::Classic - Legacy call interface to File::Util
Provides a classic interface for argument passing to and between the public and
private methods of File::Util. It is as a subclass for File::Util developers
that want to use it, and provides some base methods that are inherited by
File::Util::Interface::Modern, but the _remove_opts method is overridden in
that namespace, whose more progressive version of that method supports both
::Classic and ::Modern call syntaxes.
Users, don't use this module by itself. It is intended for
internal use only.
