NAME

       Locale::Language - standard codes for language identification

SYNOPSIS

          use Locale::Language;

          $lang = code2language('en');        # $lang gets 'English'
          $code = language2code('French');    # $code gets 'fr'

          @codes   = all_language_codes();
          @names   = all_language_names();

DESCRIPTION

       This module provides access to standard codes used for identifying languages, such as
       those as defined in ISO 639.

       Most of the routines take an optional additional argument which specifies the code set to
       use. If not specified, the default ISO 639 two-letter codes will be used.

SUPPORTED CODE SETS

       There are several different code sets you can use for identifying languages. A code set
       may be specified using either a name, or a constant that is automatically exported by this
       module.

       For example, the two are equivalent:

          $lang = code2language('en','alpha-2');
          $lang = code2language('en',LOCALE_LANG_ALPHA_2);

       The codesets currently supported are:

       alpha-2, LOCALE_LANG_ALPHA_2
           This is the set of two-letter (lowercase) codes from ISO 639-1, such as 'he' for
           Hebrew.  It also includes additions to this set included in the IANA language
           registry.

           This is the default code set.

       alpha-3, LOCALE_LANG_ALPHA_3
           This is the set of three-letter (lowercase) bibliographic codes from ISO 639-2 and
           639-5, such as 'heb' for Hebrew.  It also includes additions to this set included in
           the IANA language registry.

       term, LOCALE_LANG_TERM
           This is the set of three-letter (lowercase) terminologic codes from ISO 639.

ROUTINES

       code2language(CODE [,CODESET] [,'retired'])
       language2code(NAME [,CODESET] [,'retired'])
       language_code2code(CODE ,CODESET ,CODESET2)
       all_language_codes([CODESET] [,'retired'])
       all_language_names([CODESET] [,'retired'])
       Locale::Language::rename_language(CODE ,NEW_NAME [,CODESET])
       Locale::Language::add_language(CODE ,NAME [,CODESET])
       Locale::Language::delete_language(CODE [,CODESET])
       Locale::Language::add_language_alias(NAME ,NEW_NAME)
