Language-bars are a work-in-progress towards making the Wiki multilingual, they include a link for all the supported languages.
A language-bar is made as a separate page usually called by the English name prefixed with 'tongues'. For example, the Language-bar for a page called WikiPageName would be tonguesWikiPageName. This page is then added at the top of each page using Wikka's include function.
