* As a special exception to the GPL terms, Nmap Software LLC grants permission

* If you received these files with a written license agreement stating terms

*
* Source is provided to this software because we believe users have a right to

* allows you to audit the software for security holes.
*
* Source code also allows you to port Nmap to new platforms, fix bugs, and add
* new features. You are highly encouraged to send your changes to the

* offering the Nmap Project (Nmap Software LLC) the unlimited, non-exclusive
* right to reuse, modify, and relicense the code. Nmap will always be available
* Open Source, but this is important because the inability to relicense code
* has caused devastating problems for other Free Software projects (such as KDE
* and NASM). We also occasionally relicense the code to third parties as
* discussed above. If you wish to specify special license conditions of your
* contributions, just say so when you send them.
