Template:Language template

From Meta, a Wikimedia project coordination wiki

This is a meta-template for language-related templates. It adds Category:Other languages templates to the template and prevents the page from being included in printed versions (e.g. PDF exports).

If you don't use this template, and language selection templates are not excluded from print, it takes up about half a page, because the renderer lists it as bullet points and not as a compact form as on wiki pages.
