+# * 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 changes as a Github PR
+# * or by email to the dev@nmap.org mailing list for possible incorporation into
+# * the main distribution. Unless you 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).
