# p2 = Variable B results
# power = chance of false negative (A power of 0.80 means that there is an 80% chance that if there was an effect, we would detect it )
# sig.level = chance of false positive (0.05 = 5%)

# Motivation: you want to search in forks for an urgent fix

# I've wanted to do this a few times but couldn't find any other way to,
# so wrote this.

# 1) git clone main repo

# 2) in cloned folder, fetch all commits using script from https://gist.github.com/zaczheng/7003545

# 3) search in forks(excluding main author) for patterns in
