 # Every test is driven by its own temporary config file.
 # This program prepares the environment, creates the config and calls udev.
 #
-# udev reads the config, looks at the provided sysfs and
+# udev parses the rules, looks at the provided sysfs and
 # first creates and then removes the device node.
 # After creation and removal the result is checked against the
 # expected value and the result is printed.
 #
-# happy testing,
