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."
