With the exportation template you can customize the exportation of the project translations to the language files.
What is the exportation process? For example, you have 3 translations in your project. For the English language the 3 texts are "Home", "Directory", "Help". You can export the 3 translations to a file with a given template. For example you want the lines of your file being like «MyTranslation_[transref]="[trans]";»
Then when you export the 3 translations of your project you will create a file (that we call language file because it represents the english language for your project) that will be like this :
MyTranslation_0="Home";
MyTranslation_1="Direcotry";
MyTranslation_2="Help";
