WebCGAL defines output operators for classes that are derived from the class ostream. This allows to write to ostreams as std::cout or std::cerr, as well as to std::ostringstream and std::ofstream. The output operator is defined for all classes in the CGAL Kernel and for the class Color (see Section Colors) as well.
