A command line dice roller.
python roll.py <roll arg> <another roll arg> <and so on>
At its core, roll.py allows you to roll what you'd say: for example,
d4, or 2d8, or 10d6+15. The dice are all rolled separately, then
summed, then the modifier is applied.
roll.py also supports rounding up (^) or down (_) for division
modifiers: 3d6/2^ or 2d10/3_.
Finally, you can label each roll:
python roll.py attack:d20+5 defense:2d10+2 "power attack:1d8"
Your results will be returned in an ASCII table.
