-=head1 DESCRIPTION
-
-The C<Locale::Country> module provides access to the ISO
-codes for identifying countries, as defined in ISO 3166.
-You can either access the codes via the L<conversion routines>
-(described below), or with the two functions which return lists
-of all country codes or all country names.
-
-There are three different code sets you can use for identifying
-countries:
-
-=over 4
-
-=item B<alpha-2>
-
-Two letter codes, such as 'tv' for Tuvalu.
-This code set is identified with the symbol C<LOCALE_CODE_ALPHA_2>.
-
-=item B<alpha-3>
-
-Three letter codes, such as 'brb' for Barbados.
-This code set is identified with the symbol C<LOCALE_CODE_ALPHA_3>.
-
-=item B<numeric>
-
-Numeric codes, such as 064 for Bhutan.
-This code set is identified with the symbol C<LOCALE_CODE_NUMERIC>.
-
-=back
-
-All of the routines take an optional additional argument
-which specifies the code set to use.
-If not specified, it defaults to the two-letter codes.
-This is partly for backwards compatibility (previous versions
-of this module only supported the alpha-2 codes), and
-partly because they are the most widely used codes.
-
-The alpha-2 and alpha-3 codes are not case-dependent,
-so you can use 'BO', 'Bo', 'bO' or 'bo' for Bolivia.
-When a code is returned by one of the functions in
-this module, it will always be lower-case.
-
-As of version 2.00, Locale::Country supports variant
-names for countries. So, for example, the country code for "United States"
-is "us", so country2code('United States') returns 'us'.
-Now the following will also return 'us':
-
- country2code('United States of America')
- country2code('USA')

-
-=head1 CONVERSION ROUTINES
-
-There are three conversion routines: C<code2country()>, C<country2code()>,
-and C<country_code2code()>.
-
-=over 8
-
-=item code2country( CODE, [ CODESET ] )
-
-This function takes a country code and returns a string
-which contains the name of the country identified.
-If the code is not a valid country code, as defined by ISO 3166,
-then C<undef> will be returned:
-
- $country = code2country('fi');
-
-=item country2code( STRING, [ CODESET ] )
-
-This function takes a country name and returns the corresponding
-country code, if such exists.
-If the argument could not be identified as a country name,
-then C<undef> will be returned:
-
- $code = country2code('Norway', LOCALE_CODE_ALPHA_3);
- # $code will now be 'nor'
-
-The case of the country name is not important.
-See the section L<KNOWN BUGS AND LIMITATIONS> below.
-
-=item country_code2code( CODE, CODESET, CODESET )
-
-This function takes a country code from one code set,
-and returns the corresponding code from another code set.
-
- $alpha2 = country_code2code('fin',
- LOCALE_CODE_ALPHA_3 => LOCALE_CODE_ALPHA_2);
- # $alpha2 will now be 'fi'
-
-If the code passed is not a valid country code in
-the first code set, or if there isn't a code for the
-corresponding country in the second code set,
-then C<undef> will be returned.

-=head1 QUERY ROUTINES
-
-There are two function which can be used to obtain a list of all codes,
-or all country names:
-
-=over 8
-
-=item C<all_country_codes( [ CODESET ] )>
-
-Returns a list of all two-letter country codes.
-The codes are guaranteed to be all lower-case,
-and not in any particular order.
-
-=item C<all_country_names( [ CODESET ] )>
-
-Returns a list of all country names for which there is a corresponding
-country code in the specified code set.
-The names are capitalised, and not returned in any particular order.
-
-Not all countries have alpha-3 and numeric codes -
-some just have an alpha-2 code,
-so you'll get a different number of countries
-depending on which code set you specify.

-#-----------------------------------------------------------------------
-
-=head1 CODE ALIASING
-
-This module supports a semi-private routine for specifying two letter
-code aliases.
-
- Locale::Country::_alias_code( ALIAS => CODE [, CODESET ] )
-
-This feature was added as a mechanism for handling
-a "uk" code. The ISO standard says that the two-letter code for
-"United Kingdom" is "gb", whereas domain names are all .uk.
-
-By default the module does not understand "uk", since it is implementing
-an ISO standard. If you would like 'uk' to work as the two-letter
-code for United Kingdom, use the following:
-
- use Locale::Country;
-
- Locale::Country::_alias_code('uk' => 'gb');
-
-With this code, both "uk" and "gb" are valid codes for United Kingdom,
-with the reverse lookup returning "uk" rather than the usual "gb".
-
-=cut
-#-----------------------------------------------------------------------
-
-sub _alias_code
+#=======================================================================
+#
+# alias_code ( ALIAS => CODE [ , CODESET ] )
+#
+# Add an alias for an existing code. If the CODESET isn't specified,
+# then we use the default (currently the alpha-2 codeset).
+#
+# Locale::Country::alias_code('uk' => 'gb');
+#
+#=======================================================================
+sub alias_code
{
my $alias = shift;
my $real = shift;
return $alias;
}

+*_alias_code = *alias_code;
-=head1 EXAMPLES
-The following example illustrates use of the C<code2country()> function.
-The user is prompted for a country code, and then told the corresponding
-country name:
+#=======================================================================
+#
+# rename_country
+#
+# change the official name for a country, eg:
+# gb => 'Great Britain'
+# rather than the standard 'United Kingdom'. The original is retained
+# as an alias, but the new name will be returned if you lookup the
+# name from code.
+#
+#=======================================================================
+sub rename_country
+{
+ my $code = shift;
+ my $new_name = shift;
+ my $codeset = @_ > 0 ? shift : _code2codeset($code);
+ my $country;
+ my $c;
- $| = 1; # turn off buffering
-
- print "Enter country code: ";
- chop($code = <STDIN>);
- $country = code2country($code, LOCALE_CODE_ALPHA_2);
- if (defined $country)
- {
- print "$code = $country\n";
- }
- else
+
+ if (not defined $codeset)
{
- print "'$code' is not a valid country code!\n";
+ carp "rename_country(): unknown country code \"$code\"\n";
+ return 0;
}
-=head1 DOMAIN NAMES
-
-Most top-level domain names are based on these codes,
-but there are certain codes which aren't.
-If you are using this module to identify country from hostname,
-your best bet is to preprocess the country code.
-
-For example, B<edu>, B<com>, B<gov> and friends would map to B<us>;
-B<uk> would map to B<gb>. Any others?
-
-=head1 KNOWN BUGS AND LIMITATIONS
-
-=over 4
-
-=item *
-
-When using C<country2code()>, the country name must currently appear
-exactly as it does in the source of the module. The module now supports
-a small number of variants.
-
-Possible extensions to this are: an interface for getting at the
-list of variant names, and regular expression matches.
-
-=item *
-
-In the current implementation, all data is read in when the
-module is loaded, and then held in memory.
-A lazy implementation would be more memory friendly.
-
-=item *
-
-Support for country names in different languages.
