Internationalization.

Internationalization in Rails was a complex task until Rails version 2.2 came out with internationalization and localization support built in. Since then, launching an application in another language or even multiple languages has become a relatively simple task. According to Wikipedia, ˵Internationalization is the process of designing a software application so that it can be adapted to various languages and regions without engineering changes. Localization is the process of adapting software for a specific region or language by adding locale-specific components and translating text.″ [ABSTRACT FROM AUTHOR]
