THIS IS JUST A DRAFT OF THE NPSL WHICH MAY OR MAY NOT BE APPLIED TO NMAP SOMEDAY - CURRENT VERSIONS OF NMAP ARE ACTUALLY DISTRIBUTED UNDER THIS LICENSE INSTEAD.
Nmap is distributed under the terms of the Nmap Public Source
License. This license is based on the GNU GPLv2, but has some other
important conditions, clarifications and exceptions. It also contains a warranty
disclaimer and contributor agreement. We believe it is 100% compliant
with the Open
Source Definition, but we haven't gone through their certification
process (which requires an attorney).
The license itself is rather terse, so we have created the Annotated HTML Nmap Public Source License. This
version includes further reasoning behind and explanations of the license
terms. These annotations are not a legal document or legal advice.
If you need to know exactly what the license requires, you need
to read and understand the license itself; if you need legal advice,
talk to a lawyer.
Once we finish hashing out the license terms, we will link from
here to the latest official, non-annotated text version of the
license. Note that some releases of Nmap may fall under a previous
version of this license, or a different license entirely. The exact
terms for a given version of Nmap can be found in the included COPYING
