From b75fac5be31d6056e78fd29a0548cc3e6275a1b8 Mon Sep 17 00:00:00 2001 From: Eric Bélanger Date: Mon, 21 Nov 2011 17:21:24 -0500 Subject: pacsysclean: Add new contrib script MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit pacsysclean sort installed packages by decreasing installed size. It's useful for finding large unused package when doing system clean-up. This script is an improved version of other similar scripts posted on the forums. Thanks goes to Dan for fixing and improving my original script.
