Markus,


I know this. If we change the file format, we have to rewrite the scripts
anyways. SQLite has a bindings for all scripting languages. Perl, python,
LUA... you name it.

Think of that your scripts will be much more compact. No need to implement
parsing N times.

Generating a drill report is just one query of the database. Your script is
just to pretty print the output.
Same goes for XY files for your pick and place machine.

No, I DON'T want to start another flame war. We had enough in this list. I
write code.

Lev
