| 122 | =head1 DESCRIPTION | ||||
| 123 | |||||
| 124 | L<Sub::Exporter> is an incredibly powerful module, but with that power comes | ||||
| 125 | great responsibility, er- as well as some runtime penalties. This module | ||||
| 126 | is a C<Sub::Exporter> wrapper that will let your users just use L<Exporter> | ||||
| 127 | if all they are doing is picking exports, but use C<Sub::Exporter> if your | ||||
| 128 | users try to use C<Sub::Exporter>'s more advanced features features, like | ||||
| 129 | renaming exports, if they try to use them. | ||||
| 130 | |||||
| 131 | Note that this module will export C<@EXPORT>, C<@EXPORT_OK> and | ||||
| 132 | C<%EXPORT_TAGS> package variables for C<Exporter> to work. Additionally, if | ||||
| 133 | your package uses advanced C<Sub::Exporter> features like currying, this module | ||||
| 134 | will only ever use C<Sub::Exporter>, so you might as well use it directly. | ||||
