From 1880a3927b23f265f63b2adb86fbdb81ea09eb06 Mon Sep 17 00:00:00 2001 From: Lasse Collin Date: Wed, 19 Nov 2008 23:52:24 +0200 Subject: Renamed lzma to xz and lzmadec to xzdec. We create symlinks lzma, unlzma, and lzcat in "make install" for backwards compatibility with LZMA Utils 4.32.x; I'm not sure if this should be the default though. --- src/lzma/message.c | 892 ----------------------------------------------------- 1 file changed, 892 deletions(-) delete mode 100644 src/lzma/message.c (limited to 'src/lzma/message.c') diff --git a/src/lzma/message.c b/src/lzma/message.c deleted file mode 100644 index caba9fbc..00000000 --- a/src/lzma/message.c +++ /dev/null @@ -1,892 +0,0 @@ -/////////////////////////////////////////////////////////////////////////////// -// -/// \file message.c -/// \brief Printing messages to stderr -// -// Copyright (C) 2007-2008 Lasse Collin -// -// This program is free software; you can redistribute it and/or -// modify it under the terms of the GNU Lesser General Public -// License as published by the Free Software Foundation; either -// version 2.1 of the License, 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.
