this is step 2 of 2 of the OpenSim.Region.Environment refactor.
NOTHING has been deleted or moved off to forge at this point. what
has happened is that OpenSim.Region.Environment.Modules has been split
in two:
- OpenSim.Region.CoreModules: all those modules that are either
directly or indirectly referenced from other OpenSim packages, or
that provide functionality that the OpenSim developer community
considers core functionality:
CoreModules/Agent/AssetTransaction
CoreModules/Agent/Capabilities
CoreModules/Agent/TextureDownload
CoreModules/Agent/TextureSender
CoreModules/Agent/TextureSender/Tests
CoreModules/Agent/Xfer
CoreModules/Avatar/AvatarFactory
CoreModules/Avatar/Chat/ChatModule
CoreModules/Avatar/Combat
CoreModules/Avatar/Currency/SampleMoney
CoreModules/Avatar/Dialog
CoreModules/Avatar/Friends
CoreModules/Avatar/Gestures
CoreModules/Avatar/Groups
CoreModules/Avatar/InstantMessage
CoreModules/Avatar/Inventory
CoreModules/Avatar/Inventory/Archiver
CoreModules/Avatar/Inventory/Transfer
CoreModules/Avatar/Lure
CoreModules/Avatar/ObjectCaps
CoreModules/Avatar/Profiles
CoreModules/Communications/Local
CoreModules/Communications/REST
CoreModules/Framework/EventQueue
CoreModules/Framework/InterfaceCommander
CoreModules/Hypergrid
CoreModules/InterGrid
CoreModules/Scripting/DynamicTexture
CoreModules/Scripting/EMailModules
CoreModules/Scripting/HttpRequest
CoreModules/Scripting/LoadImageURL
CoreModules/Scripting/VectorRender
CoreModules/Scripting/WorldComm
CoreModules/Scripting/XMLRPC
CoreModules/World/Archiver
CoreModules/World/Archiver/Tests
CoreModules/World/Estate
CoreModules/World/Land
CoreModules/World/Permissions
CoreModules/World/Serialiser
CoreModules/World/Sound
CoreModules/World/Sun
CoreModules/World/Terrain
CoreModules/World/Terrain/DefaultEffects
CoreModules/World/Terrain/DefaultEffects/bin
CoreModules/World/Terrain/DefaultEffects/bin/Debug
CoreModules/World/Terrain/Effects
CoreModules/World/Terrain/FileLoaders
CoreModules/World/Terrain/FloodBrushes
CoreModules/World/Terrain/PaintBrushes
CoreModules/World/Terrain/Tests
CoreModules/World/Vegetation
CoreModules/World/Wind
CoreModules/World/WorldMap
- OpenSim.Region.OptionalModules: all those modules that are not core
modules:
OptionalModules/Avatar/Chat/IRC-stuff
OptionalModules/Avatar/Concierge
OptionalModules/Avatar/Voice/AsterixVoice
OptionalModules/Avatar/Voice/SIPVoice
OptionalModules/ContentManagementSystem
OptionalModules/Grid/Interregion
OptionalModules/Python
