+	  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 last version before the API and ABI change
+	  introduced in 3.0.0 which requires C++17.
