NAME
       Locale::Codes::LangVar - standard codes for language variation identification

SYNOPSIS
	  use Locale::Codes::LangVar;

	  $lvar = code2langvar('acm');		       # $lvar gets 'Mesopotamian Arabic'
	  $code = langvar2code('Mesopotamian Arabic'); # $code gets 'acm'

	  @codes   = all_langvar_codes();
	  @names   = all_langvar_names();

DESCRIPTION
       The "Locale::Codes::LangVar" module provides access to standard codes used for identifying
       language variations, such as those as defined in the IANA language registry.

       Most of the routines take an optional additional argument which specifies the code set to
       use. If not specified, the default IANA language registry codes will be used.

SUPPORTED CODE SETS
       There are several different code sets you can use for identifying language variations. 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:

	  $lvar = code2langvar('arevela','alpha');
	  $lvar = code2langvar('arevela',LOCALE_LANGVAR_ALPHA);

       The codesets currently supported are:

       alpha
	   This is the set of alphanumeric codes from the IANA language registry, such as
	   'arevela' for Eastern Armenian.

	   This code set is identified with the symbol "LOCALE_LANGVAR_ALPHA".

	   This is the default code set.

ROUTINES

	   These routines are all documented in the Locale::Codes::API man page.
