# * 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).       *
# *                                                                         *
