# f_read_iso3166_table
#
# Read the ISO 3166 country code database in _PATH_ISO3166:
# 	/usr/share/misc/iso3166 on FreeBSD
# 	/usr/share/zoneinfo/iso3166.tab on Linux, Mac OS X, and Cygwin
#
# The format of this file on FreeBSD is:
# 	two	three	number	name
#
# The format of this file on Linux, Mac OS X, and Cygwin is:
# 	two	name
#
# With each of the following elements (described below) being separated by a
# single tab character:
#
# 	two      ISO 3166 2-character country code
# 	three    ISO 3166 3-character country code (if provided)
# 	number   ISO 3166 numeric country code (if provided)
# 	name     Human-readable country name (may contain spaces)
#
# Variables created by this function:
#
# 	COUNTRIES
# 		A space-separated list of 2-character country codes.
# 	country_CODE_name
# 		The country `name' (as described above).
#
# where CODE is the 2-character country code.

# afterward is the sh(1) function which utilizes the below awk script.
