From 2883fcba2bf3fcff286a70c3629016a0c53a6803 Mon Sep 17 00:00:00 2001 From: Aleksander Machniak Date: Tue, 4 Nov 2014 15:28:27 +0100 Subject: Move TNEF decoder class to the Roundcube Framework (#1490055) So, for now all dependencies of the Framework can be installed with composer and we need only lib/Roundcube folder. des.inc was never required and is less important since we do encryption using openssl or mcrypt extensions. --- program/lib/tnef_decoder.php | 331 ------------------------------------------- 1 file changed, 331 deletions(-) delete mode 100644 program/lib/tnef_decoder.php (limited to 'program/lib/tnef_decoder.php') diff --git a/program/lib/tnef_decoder.php b/program/lib/tnef_decoder.php deleted file mode 100644 index e6ccc23d7..000000000 --- a/program/lib/tnef_decoder.php +++ /dev/null @@ -1,331 +0,0 @@ - - * Original design by: - * Thomas Boll , Mark Simpson - * - * Copyright 2002-2010 The Horde Project (http://www.horde.org/) - * - * See the enclosed file COPYING for license information (LGPL).
