From d37ad048732fbcef38aec001993553896dbe4198 Mon Sep 17 00:00:00 2001 From: Aaron Griffin Date: Sun, 15 Oct 2006 19:31:03 +0000 Subject: Merged frugalware changes (too many to list). Also added some config file handling changes (support [sections] to carry over to included files - this helps with backwards compatibility with existing pacman config files) --- lib/libalpm/deps.c | 92 ++++++++++++++++++++++++++++++++---------------------- 1 file changed, 55 insertions(+), 37 deletions(-) (limited to 'lib/libalpm/deps.c') diff --git a/lib/libalpm/deps.c b/lib/libalpm/deps.c index 978ffb68..f709096d 100644 --- a/lib/libalpm/deps.c +++ b/lib/libalpm/deps.c @@ -2,6 +2,8 @@ * deps.c * * Copyright (c) 2002-2006 by Judd Vinet + * Copyright (c) 2005 by Aurelien Foret + * Copyright (c) 2005, 2006 by Miklos Vajna * * This program is free software;
