|
* As a special exception to the GPL terms, Nmap Software 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

* docs/licenses/OpenSSL.txt file, and distribute linked combinations including
|

|
|
* 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 send your changes to the
|
|
* dev@nmap.org mailing list for possible incorporation into the main
|
|
* distribution. By sending these changes to Fyodor or one of the Insecure.Org
|
|
* development mailing lists, or checking them into the Nmap source code
|
|
* repository, it is understood (unless you specify otherwise) that you are
|
|
* offering the Nmap Project (Nmap Software 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.
