There is no need to modify this file: it will be generated for you by the Rebuild countries directory menu command.
The "directories file" dircountries.pra, list all the countries known by Proastro and the name of the associated directories.
Choose [Edit][Country directories] to edit the dircountries.pra file, found in the directory regrouping all the available countries (by default directory name is countries).
In the dialog that appears, you have:
Remark:
In most cases, there is no parent for a given country.
In this case, all the country files are in its associated directory.
In some case, for example if the country is very big, you may wish to divide it in several parts.
For example, for the USA, you divide the country in states, each state having its own files (lonlat.txt and z?.txt).
In the main countries directory, say countries, you will create directories
USA\Alabama, USA\Alaska and so on, one for each state and put in each directory
a lonlat.txt file and one one more z?.txt files.
After rebuilding the countries directory, you will get lonlat.pra, z?.pra and the dircountries.pra will have a record for each state:
Alabama, Alabama, USA
Alaska, Alaska, USA
and so on.
Please, edit the dircountries.pra, provided with Proastro, as an example.
