Serge (String Extraction and Resource Generation Engine) helps you set up a seamless continuous localization process for your software in a fully automated and scalable fashion. It allows developers to concentrate on maintaining resource files in just one language (e.g. English), and will take care of keeping all localized resources in sync and translated.
