Hi, I'm your GSoC student for setup script rewrite. You can get information on testing it on the wiki: http://wiki.cihar.com/pma/Devel:Config_script . Right now it's unusable but in a week I will have basic functionality implemented.
For language support I need this patch - http://crackpl.eu/select_lang.lib.php.patch - commited to trunk or have some other way of getting unfiltered language list.
Thanks, Piotr Przybylski
