# * o Integrates source code from Nmap                                      *

# * The term "Nmap" should be taken to also include any portions or derived *
# * works of Nmap.  This list is not exclusive, but is meant to clarify our *
# * interpretation of derived works with some common examples.  Our         *
# * interpretation applies only to Nmap--we don't speak for other people's  *

# * If you have any questions about the GPL licensing restrictions on using *
# * Nmap in non-GPL works, we would be happy to help.  As mentioned above,  *
# * we also offer alternative license to integrate Nmap into proprietary    *
# * applications and appliances.  These contracts have been sold to dozens  *
# * of software vendors, and generally include a perpetual license as well  *
# * as providing for priority support and updates as well as helping to     *

# * Source code also allows you to port Nmap to new platforms, fix bugs,    *

# * non-exclusive right to reuse, modify, and relicense the code.  Nmap     *

# * Free Software projects (such as KDE and NASM).  We also occasionally    *
# * relicense the code to third parties as discussed above.  If you wish to *
