       Locale::Language - standard codes for language identification


          use Locale::Language;

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

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


       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.


       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

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


       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)
       Locale::Language::rename_language_code(CODE ,NEW_CODE [,CODESET])
       Locale::Language::add_language_code_alias(CODE ,NEW_CODE [,CODESET])
       Locale::Language::delete_language_code_alias(CODE [,CODESET])
           These routines are all documented in the Locale::Codes::API man
