Each target directory in the C:\Brew MP\Targets directory contains the following language-specific subdirectories:
There is one target directory for each simulator target created. Language subdirectories are used for both simulator and devices, and you can extend it to all supported languages. The directory names are the language code for each language.
This allows the app to have a different compiled resource (BAR) file per language, so that the system can automatically select the one appropriate for the current language. It also provides for easier deployment of additional languages over time.
