From 812fd53499d308ff881751e57c1e3287498ddd0f Mon Sep 17 00:00:00 2001 From: Carl Worth Date: Tue, 21 Nov 2006 12:15:16 -0800 Subject: Add perceptualdiff program totest/pdiff. The perceptualdiff program was written by Hector Yee with contributions from Scott Corley and Mick Weiss. It is hosted at http://pdiff.sourceforge.net The source code added here was obtained by: svn co https://svn.sourceforge.net/svnroot/pdiff/trunk pdiff which gave revision 22 of the source code. The perceptualdiff program is available under the terms of the GNU GPL, so I've added a note to COPYING about this program, (and the fact that it is auxiliary only, and does not affect the license of the implementation of cairo itself). --- COPYING | 21 ++++++++++++++++++--- 1 file changed, 18 insertions(+), 3 deletions(-) (limited to 'COPYING') diff --git a/COPYING b/COPYING index 145e62966..7019cd694 100644 --- a/COPYING +++ b/COPYING @@ -1,6 +1,6 @@ Cairo is free software. -Every source file in the implementation of cairo is available to be +Every source file in the implementation[*] of cairo is available to be redistributed and/or modified under the terms of either the GNU Lesser General Public License (LGPL) version 2.1 or the Mozilla Public License (MPL) version 1.1.
