An attempt to formalize the grammar rules for "standard" dice notation. See https://en.wikipedia.org/wiki/Dice_notation for an parital and informal discription.
To "use", copy the contents of dice.bnf into an EBNF parser such as [https://bnfplayground.pauliankline.com/] (https://en.wikipedia.org/wiki/Dice_notation)
This repo is very much a work in progress. Do not use for anything remotely important.
