+# Usage: fragment_collect dev mount_dir test_path output_file
+#
+# On linux system, this script collects the fragmentation status of a 
+# particular directory. The objects under this directory SHOULD NOT be 
+# used as mount point. If they do, please umount them first, but there
+# is no danger even if you forget. The "output_file" is the one that I
+# need, please gzip it and send it back to nzhu@cs.sunysb.edu
+#
+# The program needs to be run as ROOT, but it is SAFE and KEEPS PRIVACY.
+# The pathname information on your system is completely filtered out 
+# from the final output. This program ONLY READ and DOES NOT WRITE any
+# files EXCEPT "output_file*" 
+#
+# Parameters:
+#               dev                    :the device of the directory to be measured
+#               mount_dir              :the the mount point of the device
+#               test_path              :the relative path of the directory under mount_dir
+#               output_file    :where the result is stored.
+#
+# Example: fragment_collect /dev/hda7 /home ningning /tmp/home-ningning.frag
+#
+#      This gives the fragmentation information (saved in "/tmp/home-ningning.frag")
+#   of the file system objects under the directory of "/home/ningning" on the 
+#   disk partition of "/dev/hda7" mounted to "/home".
