=head1 NAME

Dpkg::Gettext - convenience wrapper around Locale::gettext

=head1 DESCRIPTION

The Dpkg::Gettext module is a convenience wrapper over the Locale::gettext
module, to guarantee we always have working gettext functions, and to add
some commonly used aliases.

=head1 FUNCTIONS

=over 4

=item my $trans = g_($msgid)

Calls gettext() on the $msgid and returns its translation for the current
locale. If gettext() is not available, simply returns $msgid.

=item my $trans = P_($msgid, $msgid_plural, $n)

Calls ngettext(), returning the correct translation for the plural form
dependent on $n. If gettext() is not available, returns $msgid if $n is 1
or $msgid_plural otherwise.
