-/**
- * A simple wrapper to make internationalization easier to use in sources.
- *
- * Message files should be put at the `/res/raw` folder, with the name
- * `messages_{iso_639_1}.properties`, where `iso_639_1` should be using
- * snake case and be in lowercase.
- *
- * To edit the strings, use the official JetBrain's
- * [Resource Bundle Editor plugin](https://plugins.jetbrains.com/plugin/17035-resource-bundle-editor).
- *
- * Make sure to configure Android Studio to save Properties files as UTF-8 as well.
- * You can refer to this [documentation](https://www.jetbrains.com/help/idea/properties-files.html#1cbc434e)
- * on how to do so.
