/** \mainpage The OpenSceneGraph exists as a number of modules, each sitting in its own library, enclosed within its own namespace. At the very core lies the osg library. This contains the Open Scene Graph's central classes and, at the bare minimum, it is all users need to write an OpenSceneGraph program. Its only requirements are Standard C++ and OpenGL and OpenThreads. Around and alongside this sit other supporting libraries, such as osgUtil (containing visitors for app traversals, cull traversals, scene graph optimizers and so on), osgDB (for handling plug-ins, shared library loading and the like), osgText, osgParticle, etc. A full list can be seen by clicking on the Namespace List link above. Tarballs of this documentation may be downloaded from here. Enjoy! */
