Ok let me begin:
The test page, that David created is fine, there were some typos, when
copying the input elements, but nothing special. We (me and him) agreed
to create something, that will automatically recreate the page based on
the IDL input. Yes, there are some parts of the generated code, which
are static, but the input elements and buttons are created automatically
(based on the IDL attributes and functions/methods).

How it works:
./generator -i <input IDL file> -o <output HTML file>

or, when no cli options passed, it simply reads from stdin and writes to
stdout

Wrt own repository:
I would like to push this in some own directory with spice-xpi repo.

test.html in data dir).
