I'll will work on some issues on the code I found they are useful,
like some Error codes to add and rename this is easy. They will help
to fix some GIR generation messages.

For example is important to define when a parameter is an OUT one;
some functions set GdaSet* pointer to objects when called, some
GSList* should define the object type it holds, when a returned value
must be freed by the caller or not - some GValue from GdaDataModel's
are read only.

For more information look at:

Well I have used in a very basic way JavaScript using Seed, but not
python. I think Python would be very easy even for GDA UI testing.
Then on the way, may be I can send some code to you.
