# * *
# * 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 *
