From d39b1dbe627af218e49be6424857089a5888903b Mon Sep 17 00:00:00 2001
From: Xavier Chantry <shiningxc@gmail.com>
Date: Sun, 19 Jul 2009 11:15:11 +0200
Subject: Add new --print operation for all operations

And a new --print-format option to configure the output.

This implements FS#14208

Example usage :
pacman -Sp --print-format "%r/%n-%v : %l [%s]" kdelibs
extra/kdelibs-4.3.2-4 : ftp://mir2.archlinuxfr.org/archlinux/extra/os/i686/kdelibs-4.3.2-4-i686.pkg.tar.gz [0,00]
