#   Script to show and or Modify kernal params.
#   See man page for system(4) for further information.
#
#   kindly supplied by Mr. Kroonma to have a look into some kernel variables with the help of
#   the absolute debugger (adb). You can extend the script to suit your own needs, but you should
#   know what you are doing. Refer to the manual page of the
#   absolute debugger for details of displaying non-ulong datatype variables. 
#   If you don't know, what adb can do for you, hands off.
