The easiest way I would see to weight a dice roll would be like this:

:rand->x
:6->y
:y-(x<.8)->y
:y-(x<.62)->y
:y-(x<.45)->y
:y-(x<.29)->y
:y-(x<.14)->y

y contains the dice face, 1-6, with 6 chosen 1.35x as often as 1.

I had the routine run itself 1000 times and keep a tally of the results.
1=14% 2=15% 3=17% 4=17% 5=19% 6=18%
Close enough. Only 4% different.

Since u971168@daimi.aau.dk (Rene Kragh Pedersen) didn't have
the decency to take his flames to personal e-mail instead of flooding
this list, I did. I just didn't want anyone to think that I'd be rude enough
to ignore him or filter his letters.
