*** About glibmm

   glibmm is a C++ API for glib, used by gtkmm.

   glibmm 2.16 wraps new API in glib 2.16, including the new gio library,
   and is API/ABI-compatibile with glibmm 2.14, 2.12, 2.10, 2.8, 2.6 and
   2.4. It is a version of the glibmm-2.4 API.

   gtkmm and glibmm stay in-sync with GTK+ by following the official 
GNOME release schedule:

   Bindings for the rest of the GNOME Platform are also available, and 
are also
   API-stable.
