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.com) 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.
