Simply copy this script to a local binary directory like /root/bin/ or
/usr/local/bin

Either add a line in your system startup files or add a crontab entry for this
program to be executed at least once a day.
(I'm using SuSE 6.4 so the script is invoked in the script
/sbin/init.d/boot.local.)

For security purposes, I suggest you do a "chmod 700" on the script and do a
"chown root".

This script should be only invoked as root because it will erase the sys logs.
