+//
+// A class resposible for high level geometrical functions, and for
+// high level objects in the geometry subdomain.
+// The class is `singleton', with access via G4GeometryManager::GetInstance
+//
+// Member functions:
+//
+// G4bool CloseGeometry(G4bool pOptimise=true);
+//   Close (`lock') the geometry: perform sanity and `completion' checks
+//   and optionally [default=yes] Build optimisation information.
+//  
+// void OpenGeometry();
+//   Open (`unlock') the geometry and remove optimisation information if
+//   present.
+//
+// static G4GeometryManager* GetInstance()
+//   Return ptr to singleton instance of the class.
+//
+// Member data:
+//
+// static G4GeometryManager* fgInstance
+//   Ptr to the unique instance of class
+//
+// History:
+// 26.07.95 P.Kent Initial version, incuding optimisation Build
