PDF with serial included. Just run dmg, enter one of serial when asked. Good idea is also to block connections in firewall (perhaps just use MidgetSnitch for connection blocking).
Enjoy
Ps.
From my personal download of this script and my troubles.. make sure
when you copy and past the script into apple editor that it looks
EXACTLY like the pdf (ie.. whitespace and lines) If it doesn't the
script won't want to compile for you :)
