From f431cd1a48a6a5186633bf5f16a2d21cb4399e8c Mon Sep 17 00:00:00 2001 From: P. J. McDermott Date: Thu, 09 Feb 2012 10:56:43 -0500 Subject: Initial commit. TODO: Copyright information. Including source code and a patch to add files generated by GNU Autoconf is not very pretty... Running 'make dist' in the SVN trunk to generate a source archive might be better. --- (limited to 'src/libopkg/opkg_message.c') diff --git a/src/libopkg/opkg_message.c b/src/libopkg/opkg_message.c new file mode 100644 index 0000000..7114e3a --- /dev/null +++ b/src/libopkg/opkg_message.c @@ -0,0 +1,121 @@ +/* opkg_message.c - the opkg package management system + + Copyright (C) 2009 Ubiq Technologies + Copyright (C) 2003 Daniele Nicolodi + + This program is free software; you can redistribute it and/or + modify it under the terms of the GNU General Public License as + published by the Free Software Foundation; either version 2, or (at + your option) any later version. + + This program is distributed in the hope that it will be useful, but + WITHOUT ANY WARRANTY; without even the implied warranty of + MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.
