please note that this location is temporary. Once the cookbook will be
a bit more complete, it will be moved to qgis site.

Actually the intent was to introduce the QGIS API, so it probably fails :-/
I expect that someone wanting to interface qgis from python has some
python knowledge - there are many tutorials for python.

Sure, I have various scripts, though most of them are for some
specific data processing.

The cookbook shows how to load a spatialite layer and shows how to use
map canvas widget. It just doesn't show how to combine the layer and
canvas in a simple script. Is that what you are missing?

Some good and short examples can be found here:

That makes sense. A bunch of simple and commented examples will surely
be handy for beginners.
