+Sub::Exporter is an incredibly powerful module, but with that
+power comes great responsibility, as well as some runtime
+penalties. This module is a Sub::Exporter wrapper that will
+let your users just use Exporter if all they are doing is
+picking exports, but use Sub::Exporter if your users try to
+use Sub::Exporter's more advanced features features,
+like renaming exports, if they try to use them.
+Note that this module will export @EXPORT, @EXPORT_OK and
+%EXPORT_TAGS package variables for Exporter to work.
+Additionally, if your package uses advanced Sub::Exporter
+features like currying, this module will only ever use
+Sub::Exporter, so you might as well use it directly.
