* This script is a bit of a hack. It connects to another database and tries to
* run most of the question engine upgrade. That is, it loads the old data, and
* tries to convert it to the new structure, but it does not try to output it
* at all.
*
* The idea is that this should find most of the logic errors, since the code to
* save the new data to the DB is quite simple.
