=head1 NAME

Locale::Codes::Language - module for dealing with language code sets

=head1 SYNOPSIS

   use Locale::Codes::Language;

   $name = code2language(CODE);

   $code = language2code(NAME);

   @codes   = all_language_codes();

   @names   = all_language_names();

=head1 DESCRIPTION

This module provides access to language code sets.

Please refer to the L<Locale::Codes::Types> document for a description

of the code sets available.

Most of the routines take an optional additional argument which

specifies the code set to use. The code set can be specified using the

name of a code set, or the perl constant specified in the above

document.  If not specified, the default code set will be used.

=head1 ROUTINES

All routines in this module call the appropriate method in the

L<Locale::Codes> module, using an object of type: language

Please refer to the documentation of the L<Locale::Codes> module

for details about each function.

The following functions are exported automatically:

=item B<code2language(CODE [,CODESET] [,'retired'])>

See B<code2name> in L<Locale::Codes>

=item B<language2code(NAME [,CODESET] [,'retired'])>

See B<show_errors> in L<Locale::Codes> but note that the default for

the non-OO modules are to NOT produce errors.
