language packs for Scheduler 2.3 (for Joomla 1.5)

I´ve just downloaded and installed your Scheduler 2.3 (for Joomla 1.5). I read it´s multilingual (19 languages). Is it based upon Joomfish for translations? I haven´t installed Joomfish yet, but will do it soon and plan to have the site in english and french.

I wonder if the language files are installed automatically from the Scheduler´s zipfile or do I have to download them from somewhere?

Scheduler plugin detects language automatically. All localization text are stored in js-files. It gives you easy way to modify localization text in any text-editor. Plugin doesn’t use Joomlfish.
