Press ^C now if you do not have a good backup of your system.

Please make sure you are not running on battery power.  This cleanup may take
30mins of heavy I/O and this may cause problems if you lose power.

If you press enter, this script will try to auto-clean your system.  Once
complete, you will need to reboot.
