+Usage: {sys.argv[0]}
+
+Provides a GUI that displays, for each node in the database, associated
+images from EOL and Wikipedia, and allows choosing which to use. Writes
+choice data to a text file with lines of the form 'otolId1 imgPath1', or
+'otolId1', where no path indicates a choice of no image.
+
+The program can be closed, and run again to continue from the last choice.
+The program looks for an existing output file to determine what choices
+have already been made.
