Erratum

[halbtaxabo-gtkmm yahoo com]

Near the bottom of the documentation page http://www.gtkmm.org/en/documentation.html ,
under "External Documentation", there is a hyperlink labelled:
"GTK+ Reference".
Clicking on it takes one to http://www.gtk.org/api/ which gives a 403 error.
The link should be changed to point to http://library.gnome.org/devel/gtk/stable/ .
