Straped 1.0 author: Marco Del Percio 20/05/2005

Remember: this is a mulithreaded program! MSVC++ compile with /MT.
Remember: This program requires raw socket support! You can't use it on Windows XP SP2 and
if you've done MS05-019 update you'll have to re-enable raw socket support! (If you still can)
see http://seclists.org/lists/nmap-hackers/2005/Apr-Jun/0001.htm for info about this.
