From 646bbbc84b8010e0dacbeed5342cdb045f46cc49 Mon Sep 17 00:00:00 2001 From: MW Date: Wed, 27 Jun 2007 15:28:52 +0000 Subject: Some work on restructuring the namespaces / project names. Note this doesn't compile yet as not all the code has been changed to use the new namespaces. Am committing it now for feedback on the namespaces. --- OpenSim/Region/Simulation/ParcelManager.cs | 892 +++++++++++++++++++++++++++++ 1 file changed, 892 insertions(+) create mode 100644 OpenSim/Region/Simulation/ParcelManager.cs (limited to 'OpenSim/Region/Simulation/ParcelManager.cs') diff --git a/OpenSim/Region/Simulation/ParcelManager.cs b/OpenSim/Region/Simulation/ParcelManager.cs new file mode 100644 index 0000000..d15d77d --- /dev/null +++ b/OpenSim/Region/Simulation/ParcelManager.cs @@ -0,0 +1,892 @@ +/* +* Copyright (c) Contributors, http://www.openmetaverse.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.
