Looking closer at this, there's no need to modify the library to do
this. It's really easy already.

To simplify it even further. I have done the following:
    - Added a constructor to the Glade.XML class that takes a Stream
    instead of a file name.
    - Modified the sample program to embed the glade file in the
    executable.

To make it even simpler, I could add another constructor that takes an
Assembly object and a resource name. Is this a good idea?

With that, to create a Glade.XML object you could do:

Glade.XML gxml =3D new Glade.XML (Assembly.GetExecutingAssembly (), "file.g=
lade",
                                "main_widget_name", null);

May I commit?
