168 ... possibilities (additional schemas present versus no additional
169 ... schemas present), therefore a separate keyword is used.
170 # Make sure there is no schemas directory on the remote machine. A
171 # previous test suite might have left some debris there and that might
172 # lead to spurious failures, so it is better to make sure we start with a
