 Babel maintains links between translated resources. In the manager you can use the Babel Box to easily switch between the different language versions of your resources. Translations can be created automatically by Babel or defined manually.
 
 Additionally, Babel can be used to synchronize certain template variables (TVs) of translated resources which should be the same in every context (language).
