 # boulder's integration-test.py has code that knows to start and wait for the

-# boulder-interation.sh on its own. The --letsencrypt flag says to run only the
+# boulder-interation.sh on its own. The --certbot flag says to run only the
 # certbot tests (instead of any other client tests it might run). We're
 # going to want to define a more robust interaction point between the boulder
 # and certbot tests, but that will be better built off of this.
