24 * _WikiTranslation: Display pagenames and other strings in various languages.
25 * Can also be used to let a favorite translation service translate a whole page.
26 * Current favorite: translate.google.com if from_lang = en or fr
29 * <?plugin _WikiTranslation page=HomePage languages=fr ?>
30 * Translation service for HomePage into french (redirect to translate.google.com)
31 * <?plugin _WikiTranslation what=pages ?>
32 * Translation matrix of all pages with proper translations (all in pgsrc)
33 * <?plugin _WikiTranslation what=wikiwords match="W*" limit=20 ?>
34 * Translation matrix of the first 20 wikiwords matching "W*"
35 * <?plugin _WikiTranslation string=HomePage languages=fr,de,sv ?>
36 * Translation matrix for all given languages
37 * <?plugin _WikiTranslation string=HomePage ?>
38 * Translation matrix for all supported languages
39 * <?plugin _WikiTranslation string=HomePage languages=fr ?>
40 * Just return the translated string for this language.
