 # boulder's integration-test.py has code that knows to start and wait for the
 # boulder processes to start reliably and then will run the certbot
-# 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
