***********************IMPORTANT NMAP LICENSE TERMS************************
* *
* The Nmap Security Scanner is (C) 1996-2020 Insecure.Com LLC ("The Nmap *

* *
* This program is distributed under the terms of the Nmap Public Source *
* License (NPSL). The exact license text applying to a particular Nmap *
* release or source code control revision is contained in the LICENSE *
* file distributed with that version of Nmap or source code control *
* revision. More Nmap copyright/legal information is available from *
* https://nmap.org/book/man-legal.html, and further information on the *
* NPSL license itself can be found at https://nmap.org/npsl. This header *
* summarizes some key points from the Nmap license, but is no substitute *
* for the actual license text. *
* *
* Nmap is generally free for end users to download and use themselves, *
* including commercial use. It is available from https://nmap.org. *
* *
* The Nmap license generally prohibits companies from using and *
* redistributing Nmap in commercial products, but we sell a special Nmap *
* OEM Edition with a more permissive license and special features for *
* this purpose. See https://nmap.org/oem *
* *
* If you have received a written Nmap license agreement or contract *
* stating terms other than these (such as an Nmap OEM license), you may *
* choose to use and redistribute Nmap under those terms instead. *
* *
* The official Nmap Windows builds include the Npcap software *
* (https://npcap.org) for packet capture and transmission. It is under *
* separate license terms which forbid redistribution without special *
* permission. So the official Nmap Windows builds may not be *
* redistributed without special permission (such as an Nmap OEM *
* license). *
* *
* Source is provided to this software because we believe users have a *
* right to know exactly what a program is going to do before they run it. *
* This also 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 submit your *
* changes as a Github PR or by email to the dev@nmap.org mailing list *
* for possible incorporation into the main distribution. Unless you *
* specify otherwise, it is understood that you are offering us very *
* broad rights to use your submissions as described in the Nmap Public *
* Source License Contributor Agreement. This is important because we *
* fund the project by selling licenses with various terms, and also *
* because the inability to relicense code has caused devastating *
* problems for other Free Software projects (such as KDE and NASM). *
* *
* The free version of Nmap is distributed in the hope that it will be *
* useful, but WITHOUT ANY WARRANTY; without even the implied warranty of *
* MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. Warranties, *
* indemnification and commercial support are all available through the *
