|
* 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, *

|

|
* 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 (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 *
