 %description devel
 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.
 It also contains adaptor classes for connection of dissimilar callbacks and has an ease of use unmatched by other C++ callback libraries.
