Brute force? No no, it requires a fileting knife, and much
persistance and testing. It's not that bad if you write your drop
scripts as you develop the package - that's when you may actually want
to drop and recreate it over and over again, wiping out all data every
time you drop it. If you leave the drop scripts till later, well, I
dunno. Get to work with the filet knife, I guess. (I've never had
rel types I needed to drop though.)
