=head1 NAME

Locale::Codes::LangExt - module for dealing with langext code sets

=head1 SYNOPSIS

   use Locale::Codes::LangExt;

   $name = code2langext(CODE);
   $code = langext2code(NAME);

   @codes   = all_langext_codes();
   @names   = all_langext_names();

=head1 DESCRIPTION

This module provides access to langext 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: langext
Please refer to the documentation of the L<Locale::Codes> module
for details about each function.

The following functions are exported automatically:

=item B<code2langext(CODE [,CODESET] [,'retired'])>
