description         Typesafe callback framework for C++

long_description    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. \
                    This is the libsigc++-3.0 API, which installs in parallel with libsigc++-2.0. \
                    The API is not significantly different, but the implementation is far simpler, \
                    using variadic templates instead of generating C++ code from .m4 filessystem.
