Where is source code of http://developer.gnome.org/doc/API/2.0/gobject/index.html documentation ?

[KLEIN Stephane <stephane harobed org>]

Hello,

I read "GObject Reference Manual" at "http://developer.gnome.org/doc/
API/2.0/gobject/index.html". I'm on "How To define and implement a new 
GObject?" section (http://developer.gnome.org/doc/API/2.0/gobject/howto-
gobject.html) and I don't found "The sample source code associated to 
this section can be found in the documentation's source tarball, in the 
sample/gobject directory".

Where is the source of this documentation ? I've noticed "http://
svn.gnome.org/viewcvs/gobject-doc/trunk/" but it isn't corresponding 
documentation.

So, I wonder if it's good idea to add in documentation, the url to its 
source code ?

Thanks for your help,
Stephane
