/**
 * Author:   Kevin Hagel <hide@address.com>
 * Since:    April 28, 2004
 * Requires: PEAR.php, Config.php, class.ianacclister.php
 *
 * Both writes and reads a country-codes.xml file.  I suggest running
 * the writeConfig once, and then after that only rarely - for example
 * when you're sure that the IANA database has changed.
 *
 * Once the file exists, you can use this class to read from that
 * config file, and have an array keyed by the country code, for
 * example with "us"
 *
 * array['us'] = array("name" => "United States",
 *                     "page" => "http://www.iana.org/root-whois/us.htm"
 *
 * Usage(s):
 *
 * CountryConfig::writeConfig($yourXMLFile);
 *
 * $countryArray = CountryConfig::readConfig($yourXMLFile);
 *
 * Note: be sure you have write permission in the destination directory.
