Calculating probabilities from d6 dice pool (Degenesis rules for botches and triggers). Hey, I have added more code to explain the error better. Its a time saver so that you can write some code, automatically run script that sets state of the contract - thus allowing you to quickly understand how the code is working. If a contract has a lot of dependencies, it can take a while to compile - so you use autocompilation at your discretion. // Identifier of the source (used in source maps).
