From 27594eeae6f40a402bc3110f06d57975168e74e3 Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?Parm=C3=A9nides=20GV?= Date: Thu, 4 Jun 2015 19:20:15 +0200 Subject: ics-openvpn as a submodule! beautiful ics-openvpn is now officially on GitHub, and they track openssl and openvpn as submodules, so it's easier to update everything. Just a git submodule update --recursive. I've also set up soft links to native modules from ics-openvpn in app, so that we don't copy files in Gradle (which was causing problems with the submodules .git* files, not being copied). That makes the repo cleaner. --- app/lzo/examples/dict.c | 274 ------------------------------------------------ 1 file changed, 274 deletions(-) delete mode 100644 app/lzo/examples/dict.c (limited to 'app/lzo/examples/dict.c') diff --git a/app/lzo/examples/dict.c b/app/lzo/examples/dict.c deleted file mode 100644 index 3ccc9a53..00000000 --- a/app/lzo/examples/dict.c +++ /dev/null @@ -1,274 +0,0 @@ -/* dict.c -- example program: how to use preset dictionaries - - This file is part of the LZO real-time data compression library. - - Copyright (C) 1996-2014 Markus Franz Xaver Johannes Oberhumer - All Rights Reserved. - - The LZO library 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 of - the License, or (at your option) any later version. - - The LZO library 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.
