phpmyadmin/libraries/plugins/export

This directory holds export plugins for phpMyAdmin. Any new plugin should
basically follow the structure presented here. Official plugins need to
have str* messages with their definition in language files, but if you build
some plugins for your use, you can directly use texts in plugin.
