A handy utility (at least for me)

[Mario Lobo]

Hi;

My  /usr/ports directory was occuping 24 gigs, of which 20 was just from the 
'work' directories !

Removing them one by one was a pain so I wrote this little utility to wipe 
them off.

If you find it useful, pass it on. Its not a big deal but thanks for keeping 
the credits on it.

Last but not least:

"if any 'member' of your hard disk is caught and killed, the programer will 
deny any knowledge of your actions. This program will NOT self-destruct in 5 
seconds."
