+This script will run the program on each data file. To quit the program hit `q`.
+If not all files have been used it will go to the next one; otherwise the script
+will be finished. To end the script early send intr/ctrl-c.
+
+The script will give you instructions on how to use the program and things to
+try each time it is run, as a helpful reminder.
