# * license Nmap technology such as host discovery, port scanning, OS       *
# * detection, and version detection.                                       *

# * Note that the GPL places important restrictions on "derived works", yet *
# * it does not provide a detailed definition of that term.  To avoid       *
# * misunderstandings, we consider an application to constitute a           *
# * "derivative work" for the purpose of this license if it does any of the *
# * following:                                                              *
# * o Integrates source code from Nmap                                      *
# * o Reads or includes Nmap copyrighted data files, such as                *
# *   nmap-os-db or nmap-service-probes.                                    *
# * o Executes Nmap and parses the results (as opposed to typical shell or  *
# *   execution-menu apps, which simply display raw Nmap output and so are  *
# *   not derivative works.)                                                * 
# * o Integrates/includes/aggregates Nmap into a proprietary executable     *
# *   installer, such as those produced by InstallShield.                   *
# * o Links to a library or executes a program that does any of the above   *
# *                                                                         *
# * 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  *
# * GPL works.                                                              *

# * 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     *
# * fund the continued development of Nmap technology.  Please email        *
# * sales@insecure.com for further information.                             *
# *                                                                         *
# * As a special exception to the GPL terms, Insecure.Com LLC grants        *
# * permission to link the code of this program with any version of the     *
# * OpenSSL library which is distributed under a license identical to that  *
# * listed in the included COPYING.OpenSSL file, and distribute linked      *
# * combinations including the two. You must obey the GNU GPL in all        *
# * respects for all of the code used other than OpenSSL.  If you modify    *
# * this file, you may extend this exception to your version of the file,   *
# * but you are not obligated to do so.                                     *
# *                                                                         *
# * If you received these files with a written license agreement or         *
# * contract stating terms other than the terms above, then that            *
# * alternative license agreement takes precedence over these comments.     *
# *                                                                         *
# * 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 (none     *
# * have been found so far).                                                *

# * Source code also allows you to port Nmap to new platforms, fix bugs,    *
# * and add new features.  You are highly encouraged to send your changes   *
# * to nmap-dev@insecure.org for possible incorporation into the main       *
# * distribution.  By sending these changes to Fyodor or one of the         *
# * Insecure.Org development mailing lists, it is assumed that you are      *
# * offering the Nmap Project (Insecure.Com LLC) the unlimited,             *
# * non-exclusive right to reuse, modify, and relicense the code.  Nmap     *
# * will always be available Open Source, but this is important because the *
# * inability to relicense code has caused devastating problems for other   *
# * Free Software projects (such as KDE and NASM).  We also occasionally    *
# * relicense the code to third parties as discussed above.  If you wish to *
# * specify special license conditions of your contributions, just say so   *
# * when you send them.                                                     *
# *                                                                         *
