From the developer:
LanguageTranslator is an application that adds two features to the Xcode Source Editor. The "Into Primary Language" command in 'Translate Language' translates and replaces the selected text from Secondary Language to Primary Language. The "Into Secondary Language" command performs the vice versa action. The application uses Google translation service as a translation engine.
