        __PACKAGE__->config(
            'TraitFor::Request::PerLanguageDomains' => {
                default_language => 'de',

        # Config::General style:
        <TraitFor::Request::PerLanguageDomains>

            selectable_language de
            selectable_language en
        </Catalyst::Request>

DESCRIPTION
    Extends Catalyst::Request objects with a "$ctx->request->language"
    method for language detection.

METHODS
  language
        my $language = $ctx->request->language;

    Returns a string that is the two digit code ISO for the request
    language.

    The following things are checked to find the request language, in order:

    *   The lang part of the domain (e.g. de from de.example.org)

    *   The "language" key set in the session (if Catalyst::Plugin::Session
        is loaded)

    *   The "Accept-Language" header of the request.

SEE ALSO
    CatalystX::RoleApplicator, I18N::AcceptLanguage.
