Hello nginx!

Iam trying to identify all my visitors based on their continent region, 
i want to log this info in each log entry. There is no geoip database 
for continent region so I want to map manually the countries within 
their regions.

I already have the GeoIP db loaded, and an example map for a region as 

  map $geoip_country_code $north_africa {
         default "";
         ##Northern Africa
         DZ 1; #"Algeria"
         EG 1; #"Egypt"
         EH 1; #"Western Sahara"
         LY 1; #"Libyan Arab Jamahiriya"
         MA 1; #"Morocco"
         SD 1; #"Sudan"
         TN 1; #"Tunisia"

Would anybody kindly offer me an example of how to generate a variable I 
can use in the logging that would print "NorthAfica" if one of the 
countries in the map matched?
