+When running the development server, every source file is watched and parsed for changed messages.
 
 Messages files are updated on the fly.
 If new definition is found, this definition is added at the end of every used `src/messages/xx-XX.json` file so when commiting, new translations are at the tail of file.
 When untranslated message is removed and if it's `message` field is empty too, message is deleted from all translation files. This is reason why `files` array is present.
