+# Purpose of this script:
+#
+# Inputs: music player model name and a file name
+#
+# Action: Build a valid mi4 file (prepending and appending magic)
+#         Encrypt the file with TEA encryption so that the model's own
+#         bootloader accepts this file.
+#         Sign the file with a DSA signature the bootloader accepts
+#
+# Output: A built, encrypted and signed mi4 file image.
+#
+# Requirement:
+#
+# This script assumes that you have the mi4code tool in your path, that
+# you have the environment variable MI4CODE pointing to the tool or that you
+# have it in the same dir that you invoke this script with.
+#
+# mi4 info and tool are here: http://daniel.haxx.se/sansa/mi4.html
