55# Read the ISO 3166 country code database in _PATH_ISO3166:
56# 	/usr/share/misc/iso3166 on FreeBSD
57# 	/usr/share/zoneinfo/iso3166.tab on Linux, Mac OS X, and Cygwin
58#
59# The format of this file on FreeBSD is:
60# 	two	three	number	name
61#
62# The format of this file on Linux, Mac OS X, and Cygwin is:
63# 	two	name
64#
65# With each of the following elements (described below) being separated by a
66# single tab character:
67#
68# 	two      ISO 3166 2-character country code
69# 	three    ISO 3166 3-character country code (if provided)
70# 	number   ISO 3166 numeric country code (if provided)
71# 	name     Human-readable country name (may contain spaces)
72#
73# Variables created by this function:
74#
75# 	COUNTRIES
76# 		A space-separated list of 2-character country codes.

78# 		The country `name' (as described above).
