The * + * installers produced by InstallShield are an example of this. Including * + * Nmap with other software in compressed or archival form does not * + * trigger this provision, provided appropriate open source decompression * + * or de-archiving software is widely available for no charge.

Other people may interpret * + * the plain GPL differently, so we consider this a special exception to * + * the GPL that we apply to Covered Software. Works which meet any of * + * these conditions must conform to all of the terms of this license, * + * particularly including the GPL Section 3 requirements of providing * + * source code and allowing free redistribution of the work as a whole. * + * * + * As another special exception to the GPL terms, the Nmap Project 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 docs/licenses/OpenSSL.txt file, and distribute * + * linked combinations including the two. * + * * + * The Nmap Project has permission to redistribute Npcap, a packet * + * capturing driver and library for the Microsoft Windows platform. * + * Npcap is a separate work with it's own license rather than this Nmap * + * license. Since the Npcap license does not permit redistribution * + * without special permission, our Nmap Windows binary packages which * + * contain Npcap may not be redistributed without special permission. * + * * + * Any redistribution of Covered Software, including any derived works, * + * must obey and carry forward all of the terms of this license, including * + * obeying all GPL rules and restrictions.

All GPL references to "this License", are to be treated as * + * including the terms and conditions of this license text as well. * + * * + * Because this license imposes special exceptions to the GPL, Covered * + * Work may not be combined (even as part of a larger work) with plain GPL * + * software. The terms, conditions, and exceptions of this license must * + * be included as well. This license is incompatible with some other open * + * source licenses as well. In some cases we can relicense portions of * + * Nmap or grant special permissions to use it in other open source * + * software. Please contact fyodor@nmap.org with any such requests. * + * Similarly, we don't incorporate incompatible open source software into * + * Covered Software without special permission from the copyright holders. * + * * + * If you have any questions about the licensing restrictions on using * + * Nmap in other works, are happy to help.
