D:\svn\gametools\OGRE\trunk\ogre_dependencies 
D:\svn\gametools\OGRE\trunk\ogre_changes\Ogre1.2

They are located in D:\svn\gametools\GTP\trunk\Lib\Vis\OnlineCullingCHC\scripts

terrainCulling.cfg: defines the scene and the visibility environment
terrain.cfg: defines the terrain structures for the terrain scene
resources.cfg: adds models and texture definitions to the Ogre resource path
Plugins.cfg: the Plugin_VisibilitySceneManager has to be registered there

8) TestCullingTerrain is the test application

take the path to the Ogre Release as working directory, e.g.,
D:\svn\gametools\OGRE\trunk\ogrenew\Samples\Common\bin\Release
