|
|
# * Nmap is generally free for end users to download and use themselves, *
|
|

|
|
# * *
|
|
# * The Nmap license generally prohibits companies from using and *
|
|
# * redistributing Nmap in commercial products, but we sell a special Nmap *
|
|
# * OEM Edition with a more permissive license and special features for *
|
|
# * this purpose. See https://nmap.org/oem/ *
|
|
# * *
|
|
# * If you have received a written Nmap license agreement or contract *
|
|

|
|
# * choose to use and redistribute Nmap under those terms instead. *
|
|
# * *
|
|
# * The official Nmap Windows builds include the Npcap software *
|
|
# * (https://npcap.com) for packet capture and transmission. It is under *
|
|
# * separate license terms which forbid redistribution without special *
|
|
# * permission. So the official Nmap Windows builds may not be *

|
|
# * 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 submit your *
|
|

|
|
# * specify otherwise, it is understood that you are offering us very *
|
|
# * broad rights to use your submissions as described in the Nmap Public *
|
|
# * Source License Contributor Agreement. This is important because we *
|
|
# * fund the project by selling licenses with various terms, and also *
|
|
# * because the inability to relicense code has caused devastating *
|
|
# * problems for other Free Software projects (such as KDE and NASM). *

# Print the topology graphic. The graphic is already made with Cairo so the

# Add options to the print dialog to control the font, coloring, and anything
