The majority of users don't really care what is going on behind the scenes.
Unfortunately, we are software guys, and we do. :-)

I don't want to fool you. I'm happy that you are a kind of person, who
actually does something, and not just hang around.

I don't have much knowledge on SQL. And I don't really feel that I'm
something special. I just browsed the gEDA/PCB code and I get a feeling
that life would be much easier if we had that SQL thing as the data
structure.

In the other hand, I don't think the vast majority of users actually would
hack an xml. It is pain.

I see no difference here.

Okay. Don't get me wrong. I don't care if it is SQL, or not. I just state
that if we use SQLite, we pull in lots of work. Your work has a value! I
suggest we concentrate on the PCB part, and not doing something which is
already done.

That is all I say.

BTW, what is your recommendation? Would you use xml? Would you roll your own
file format?
