If L<Locale::Messages> can't be loaded (it's not a core module) we provide stub passthrough fallbacks. This is a distilled interface to gettext, see C<info '(gettext)Perl'> for the full interface. This module implements only a small part of it. =head1 FUNCTIONS =head2 __($) L<Locale::Messages>'s gettext function if all goes well, otherwise our passthrough fallback function. =head2 __n($$$) L<Locale::Messages>'s ngettext function or passthrough fallback function. =head2 N__($) No-operation that only returns its argument. Use this if you want xgettext to extract the text to the pot template but do not want to trigger retrival of the translation at run time. =head1 AUTHOR E<AElig>var ArnfjE<ouml>rE<eth> Bjarmason <avarab@gmail.com> =head1 COPYRIGHT Copyright 2010 E<AElig>var ArnfjE<ouml>rE<eth> Bjarmason <avarab@gmail.com> =cut ��
