david ed2ba4e168 Copy nping, nsock, nbase, zenmap, ncat from their homes in /. 
If you have trouble updating after this revision you need to follow
these instructions. You have probably just seen an error like this:

svn: URL 'svn://svn.insecure.org/nping' of existing directory 'nping'
does not match expected URL 'svn://svn.insecure.org/nmap/nping'

This is caused by the replacement of SVN externals.

Here's what you need to do. First, save any local changes you might have
in the nping, nsock, nbase, ncat, and zenmap directories. (For example
by running "cd nping; svn diff > ../nping.diff".) If you don't have any
local changes you can skip this step.

Then run these commands:

rm -rf nping/ nsock/ nbase/ ncat/ zenmap/
svn update
svn cleanup

If all else fails, you can just delete your whole working directory and
check out anew:

svn co --username guest --password "" svn://svn.insecure.org/nmap

There may be further discussion in the mailing list thread at
http://seclists.org/nmap-dev/2011/q4/303.

# * (contact sales@insecure.com). Dozens of software vendors already *
# * license Nmap technology such as host discovery, port scanning, OS *
# * detection, and version detection. *
# * *
# * Note that the GPL places important restrictions on "derived works", yet *
# * it does not provide a detailed definition of that term. To avoid *
# * misunderstandings, we consider an application to constitute a *
# * "derivative work" for the purpose of this license if it does any of the *
# * following: *
# * o Integrates source code from Nmap *
# * o Reads or includes Nmap copyrighted data files, such as *
# * nmap-os-db or nmap-service-probes. *
# * o Executes Nmap and parses the results (as opposed to typical shell or *
# * execution-menu apps, which simply display raw Nmap output and so are *
# * not derivative works.) *
# * o Integrates/includes/aggregates Nmap into a proprietary executable *
# * installer, such as those produced by InstallShield. *
# * o Links to a library or executes a program that does any of the above *
# * *
# * The term "Nmap" should be taken to also include any portions or derived *
# * works of Nmap. This list is not exclusive, but is meant to clarify our *
# * interpretation of derived works with some common examples. Our *
# * interpretation applies only to Nmap--we don't speak for other people's *
# * GPL works. *
# * *
# * If you have any questions about the GPL licensing restrictions on using *
# * Nmap in non-GPL works, we would be happy to help. As mentioned above, *
# * we also offer alternative license to integrate Nmap into proprietary *
# * applications and appliances. These contracts have been sold to dozens *
# * of software vendors, and generally include a perpetual license as well *
# * as providing for priority support and updates as well as helping to *
# * fund the continued development of Nmap technology. Please email *
# * sales@insecure.com for further information. *
# * *
# * As a special exception to the GPL terms, Insecure.Com 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 the two. You must obey the GNU GPL in all *
# * respects for all of the code used other than OpenSSL. If you modify *
# * this file, you may extend this exception to your version of the file, *
# * but you are not obligated to do so. *
# * *
# * If you received these files with a written license agreement or *
# * contract stating terms other than the terms above, then that *
# * alternative license agreement takes precedence over these comments. *
# * *
# * 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 (none *
# * have been found so far). *
# * *
# * 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 nmap-dev@insecure.org for possible incorporation into the main *
# * distribution. By sending these changes to Fyodor or one of the *
# * Insecure.Org development mailing lists, it is assumed 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 contributions, just say so *
# * when you send them. *
