From 3d8219f6c7faa256d6a13ab7925f75d83af95b78 Mon Sep 17 00:00:00 2001 From: MW Date: Mon, 29 Oct 2007 21:46:25 +0000 Subject: as per the "Filesystem cleanup for OpenSim repository" mailing list thread. Have flattened the OpenSim.Framework project/namespace. The problem is that the namespace is still wrong as its "OpenSim.Framework" while the directory is "OpenSim\Framework\General" , so we need to decide if we change the directory or correct the namespace. Note this has lead to a big flat project, but I think a lot of the files we most likely don't even use any longer. And others belong in other projects/namespaces anyway. --- OpenSim/Framework/General/PolicyManager/ACL.cs | 257 ------------------------- 1 file changed, 257 deletions(-) delete mode 100644 OpenSim/Framework/General/PolicyManager/ACL.cs (limited to 'OpenSim/Framework/General/PolicyManager') diff --git a/OpenSim/Framework/General/PolicyManager/ACL.cs b/OpenSim/Framework/General/PolicyManager/ACL.cs deleted file mode 100644 index b6f2966..0000000 --- a/OpenSim/Framework/General/PolicyManager/ACL.cs +++ /dev/null @@ -1,257 +0,0 @@ -/* -* Copyright (c) Contributors, http://opensimulator.org/ -* See CONTRIBUTORS.TXT for a full list of copyright holders. -* -* Redistribution and use in source and binary forms, with or without -* modification, are permitted provided that the following conditions are met: -* * Redistributions of source code must retain the above copyright -* notice, this list of conditions and the following disclaimer. -* * Redistributions in binary form must reproduce the above copyright -* notice, this list of conditions and the following disclaimer in the -* documentation and/or other materials provided with the distribution. -* * Neither the name of the OpenSim Project nor the -* names of its contributors may be used to endorse or promote products -* derived from this software without specific prior written permission. -* -* THIS SOFTWARE IS PROVIDED BY THE DEVELOPERS AS IS AND ANY -* EXPRESS OR IMPLIED WARRANTIES, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED -* WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE ARE -* DISCLAIMED.
