#
# 	name         Name of the country as read from _PATH_ISO3166.
# 	nzones       Number of zones within the country (-1 if country has
# 	             only a single zone).
# 	filename     The filename portion of the TZ field (after the `/') as
# 	             read from _PATH_ZONETAB.
# 	cont         The principal continent in which the country lies (appears
# 	             before the `/' in the TZ field of _PATH_ZONETAB).
# 	filename_N   Like filename, but for the Nth zone when the country has
# 	             multiple zones (nzones > 0).
# 	cont_N       Like cont, but for the Nth zone when the country has
# 	             multiple zones (nzones > 0).
# 	descr_N      Like name, but for the Nth zone when the country has
# 	             multiple zones (nzones > 0)
