Adding these two YMLs will create collections for a seven continent configuration (as opposed to the six UN regions used by the default continent.yml) and a version of the countries.yml which groups countries with low output that are culturally similar - such as 'Balkans', 'Nordic', 'Middle East' and 'Pacific Island'.
The entry overlay file adds a country flag defined by the audio language of the entry. So Mayan gets a Mexican flag, and English gets an English flag for instance.
