+supported dozens of different OpenGL and DirectX profile targets.  It allowed
+developers to incorporate interactive effects within 3D applications and share
+them among other Cg applications, across graphics APIs, and most operating
+systems as well as balance effect complexities with client GPU capabilities.
+
+The Cg Toolkit is a legacy NVIDIA toolkit no longer under active development
+or support.  It is not recommended using it in new development projects
+because future hardware features may not be supported.  Going forward, new
+development should opt for GLSL rather than Cg.")
