Sub::Exporter is an incredibly powerful module, but with that power comes great responsibility, er- 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, 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.
