    fi
  fi

  banner "GOOD!" 32
}

function good? {
  (export REPORT_COVERAGE=true; s && c && cop && good_message) || banner "NOT GOOD" "31"
}

what does the 32 and 33 do at the end of lines 8 and 13?

@alkesh I've updated the gist to include all of the dependent functions, which is probably enough to explain that:

banner accepts two arguments, the text and the colour, 31 is red, 32 is green and 33 is yellow.

The traffic lights of code quality :)
