+     "Open CASCADE is a set of libraries for the development of applications
+dealing with 3D CAD data or requiring industrial 3D capabilities.  It includes
+C++ class libraries providing services for 3D surface and solid modeling, CAD
+data exchange, and visualization.  It is used for development of specialized
+software dealing with 3D models in design (CAD), manufacturing (CAM),
+numerical simulation (CAE), measurement equipment (CMM), and quality
+control (CAQ) domains.
+
+This is the ``Community Edition'' (OCE) of Open CASCADE, which gathers
+patches, improvements, and experiments contributed by users over the official
+Open CASCADE library.")
