 jQuery.i18n is a jQuery based Javascript internationalization library. It helps you to internationalize your web applications easily.
 
 This is a project by Wikimedia foundation's [Language Engineering team](https://www.mediawiki.org/wiki/Wikimedia_Language_engineering) and used in some of the Wikimedia Foundation projects like Universal Language Selector.
 
 The jquery.i18n library uses a json based localization file format, "banana", which is used as the localization file format for  MediaWiki and other projects.
