Template:Call lang
Usage
For calling of a translated file, with fallback to English version if translation does not exist.
{{call_lang|Installation|nl|de installatie pagina}}
The above calls Installation/nl if it exists, and otherwise the page Installation. In both cases the text returned is de installatie pagina: de installatie pagina.
Another example:
{{call_lang|Gramps:About|nl|info pagina}}
which gives: info pagina.
