Cocoa Localization Framework for OS X, which uses Transifex ( http://www.transifex.com ) as its basis. Kamusi (Suaheli for 'dictionary') consists of few Cocoa classes doing all the work.
The Kamusi Cocoa framework is meant to be used by application developers to let their application be localized by its users. The framework checks whether there is a Transifex project registered for the current application and uses the cloud localizations directly for presentation in the user's preferred language.
As a result, Kamusi allows to localize the active application on the fly. This approach has the advantage that an application can be localized quickly by its user base.
