   3 # This script generates a "memstick image" (image that can be copied to a
   4 # USB memory stick) from a directory tree.  Note that the script does not
   5 # clean up after itself very well for error conditions on purpose so the
   6 # problem can be diagnosed (full filesystem most likely but ...).
