+The various directories are -

+.git            Used by git for it's internal accounting, and the older versions.
+
+.nant           Used by the nant build tool.
+
+OpenSim         OpenSim source code.
+
+Prebuild        Used by the build system.
+
+ThirdParty      For third party OpenSim modules.
+
+addon-modules   Also for third party modules.  Don't ask me why there's two.
+
+bin             The OpenSim binaries, and other files.
+
+doc             Supposedly for documentation, which I wish OpenSim devs would write some.
+
+scripts         Various Linux scripts for managing OpenSim.
+
+share           No idea really.
+
+Also, the installation script moves the following directories to outside
+of this main directory, they are all used for writing various things. 
+Makes it easy to upgrade, and separates them from actual executable
+stuff.
+
+AssetFiles      Stores assets if running in grid mode.
+
+backups         All sim and inventory backups are stored here.
+
+caches          Various cached things.
+
+config          All your configurtion files.
+
+db              If you are not using MySQL, your data lives here.
+
+logs            Log files get stored here.
