+      gtkmm is the official C++ interface for the popular GUI library
+      GTK.  Highlights include typesafe callbacks, and a
+      comprehensive set of widgets that are easily extensible via
+      inheritance.  You can create user interfaces either in code or
+      with the Glade User Interface designer, using libglademm.
+      There's extensive documentation, including API reference and a
