Android's lint will give warnings for all strings that are not translatable
or translated. Some strings like repo name/description and language codes
should never be translated. Here's how to officially mark as "do not
translate":
* for individual strings, include: translatable="false"
* for the entire file, name it: donottranslate.xml
