+# A program for displaying images. Reads pairs of lines from the
+# file named in argv[1] and parses them to trials as follows:
+#   <filename> <min-time> <max-time> <list-of-keys>
+#   <trial description>
+# For each trial
+#   - shows the named picture centered on screen
+#   - waits for min-time 
+#   - waits until any key in the list is pressed
+#     or until max-time is reached
+#  - logs the elapsed time and the pressed key (if any)
+#    in the file named in argv[2] (default "disp.log")
