# Space-separated list of 2-character country codes.
# country_*_name :: when country_*_nzones < 0
# Desired menu text for the country-zone represented by *, the 2-
# character country code.
#
# Required variables [created by f_read_zones from zones.subr]:
#
# country_*_nzones
# Number of zones for the country represented by *, the 2-
# character country code. Should be -1 if the country has only
# one single zone, otherwise 1 or greater to indicate how many
# zones the country has.
# country_*_cont :: when country_*_nzones < 0
# Principal continent (or ocean) in which the country-zone
# represented by *, the 2-character country code, resides.

# Principal continent (or ocean) in which zone-N of the country
# represented by * resides, the 2-character country code.
# country_*_descr_N :: when country_*_nzones > 0
# Desired submenu text for zone-N of the country represented by
# *, the 2-character country code.

# continent_menu_list
# Menu-list of continents.
# continent_*_nitems
# Number of items associated with the continent represented by *,
