+# --------------
+# This program sends several commands to the coretest_hashed subsystem
+# in order to verify the SHA-1 and SHA-256 hash function cores.
+# The program uses the built in hash implementations in Python
+# to do functional comparison and validation.
+#
+# Note: This program requires the PySerial module.
