== Template ==
''This sub-template doesn't display properly when not included.  Please see [[Template:Languages]] for the complete version.''

== Usage ==

This template is designed to simplify [[Template:Languages]], by allowing a simpler syntax for adding new languages.  Each language is included by calling this template with the following parameters:

* '''Language code''' (e.g. fr)
* (optional) '''Page name''' - if not supplied the page is automatically worked out based on where the language template is included.

This template should not be used anywhere except in the Languages template.
