[GtkGLExt] Documentation gone?

[jody <jody xha gmail com>]

Hi

When i try to get the gtkglext reference by clicking
on the link 'GtkGLExt Reference Manual'
on
  http://projects.gnome.org/gtkglext/doc.html

i get the message
   Not Found

   The requested URL /gtkglext/reference/gtkglext/ was not found on this server.

Does anybody n^know where it has been moved to?

Thank You
  Jody
