Europa Universalis 3 Wiki

This file is located in the common folder.

It's where country tags are defined. If you want to add a new country, you define a unique three-letter tag here, and link it to a country definition file. A tag definition looks like this:

VIJ 	 = "countries/Vijaynagara.txt"

This defines the tag VIJ, and links it to the definition found in the file listed. The path to the file is relative to the common folder. The file can have any name you want, but it is best to use the country name to avoid confusion.
