+	  gstreamermm provides C++ bindings for the GStreamer streaming
+	  multimedia library (http://gstreamer.freedesktop.org). With
+	  gstreamermm it is possible to	develop applications that work
+	  with multimedia in C++.
+
+	  gstreamermm is developed over glibmm, libsigc++ and libxml++
+	  and the functionalities they provide. This means that, among
+	  other things, referencing and unreferencing of GObjects is
+	  handled automatically via glibmm's automatic pointer class,
+	  Glib::RefPtr, and libsigc++'s slots are used for callbacks and
+	  signals.
