The repo contains a Homebrew formula for barnardb/cookies.
brew install barnardb/cookies/cookies
Or brew tap barnardb/cookies and then brew install cookies.
Or install via URL (which will not receive updates):
brew install https://raw.githubusercontent.com/barnardb/homebrew-cookies/master/Formula/cookies.rbRun ./update.sh to check if there's a new upstream release and make and push an update to the formula if there is.
Run ./check-reinstall-test.sh after making other changes to the formula
to see if there's a newer upstream version,
if brew has any opinions about improving the formula,
and if the we can successfully install the formula.
