72
73	print __("Welcome to Git!\n");

80=head1 DESCRIPTION
81
82Git's internal Perl interface to gettext via L<Locale::Messages>. If
83L<Locale::Messages> can't be loaded (it's not a core module) we
84provide stub passthrough fallbacks.
85
86This is a distilled interface to gettext, see C<info '(gettext)Perl'>
87for the full interface. This module implements only a small part of
88it.
89
90=head1 FUNCTIONS
91
92=head2 __($)
93
94L<Locale::Messages>'s gettext function if all goes well, otherwise our
95passthrough fallback function.
96
97=head2 __n($$$)
98
99L<Locale::Messages>'s ngettext function or passthrough fallback function.
100
101=head2 N__($)
102
103No-operation that only returns its argument. Use this if you want xgettext to
104extract the text to the pot template but do not want to trigger retrival of the
105translation at run time.
