=head1 NAME
Git::I18N - Perl interface to Git's Gettext localizations
=head1 SYNOPSIS
use Git::I18N;
print __("Welcome to Git!\n");
printf __("The following error occured: %s\n"), $error;
=head1 DESCRIPTION
Git's internal Perl interface to gettext via L<Locale::Messages>. If
L<Locale::Messages> can't be loaded (it's not a core module) we
provide stub passthrough fallbacks.
This is a distilled interface to gettext, see C<info '(gettext)Perl'>
for the full interface. This module implements only a small part of
it.
=head1 FUNCTIONS
=head2 __($)
L<Locale::Messages>'s gettext function if all goes well, otherwise our
passthrough fallback function.
