The Lingua Localization jQuery Plugin makes it fast and easy for developers to translate web user interfaces into other languages and handle many other localization-driven concerns. The high-level description is that it loads plain-text key-value pairs from files which are named according to the language they contain. Developers can use this to store the raw text which goes into the user interface, internal text such as alert-box content, or even flags and other textual data that is language-driven.
