libsigc++:
libsigc++: libsigc++ implements a typesafe callback system for standard C++.
libsigc++: It allows you to define signals and to connect those signals to any
libsigc++: callback function, either global or a member function, regardless
libsigc++: of whether it is static or virtual. It also contains adaptor classes
libsigc++: for connection of dissimilar callbacks.
