SoBaseKit(3) on Linux
The text 2f9cfc72722f, as Debian 4.0 (Etch) shipped it.
The SoBaseKit class is the toplevel superclass for nodekits. Node kits are collections of nodes and other node kits (from here on node kits which is part of some other node kit, will only be referred to as nodes or parts, see catalogs and parts), organized in a way that is convenient for its use. A node kit inherits SoNode and can thus be inserted into a scenegraph as any other node.
