 %description
-Originally part of the Gtk-- widget set, libsigc++20 is now a separate library to provide
-for more general use. It is the most complete library of its kind with the ability to
-connect an abstract callback to a class method, function, or function object.
-It contains adaptor classes for connection of dissimilar callbacks and has an ease of use
-unmatched by other C++ callback libraries.
+libsigc++ implements a typesafe callback system for standard C++. It
+allows you to define signals and to connect those signals to any
+callback function, either global or a member function, regardless of
+whether it is static or virtual.
+
+libsigc++ is used by gtkmm to wrap the GTK+ signal system. It does not
+depend on GTK+ or gtkmm.
