# *
# * The Nmap license generally prohibits companies from using and

# * If you have received a written Nmap license agreement or contract

# *
# * 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

# * 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).
