MODIFIED ACADEMIC PUBLIC LICENSE

This license has been modified from the OMNeT++ license, which was written by
Andras Varga (license text is in public domain), as obtained at
<https://omnetpp.org/intro/license>


Preamble

This license contains the terms and conditions of using The Software in
noncommercial settings: at academic institutions for teaching and research use,
and at non-profit research organizations. You will find that this license
provides noncommercial users of The Software with rights that are similar to the
well-known GNU General Public License, yet it retains the possibility for the
Software authors to financially support the development by selling commercial
licenses. In fact, if you intend to use The Software in a “for-profit”
environment, where research is conducted to develop or enhance a product, is
used in a commercial service offering, or when a commercial company uses the
Software to participate in a research project (for example government-funded or
EU-funded research projects), then you need to obtain a commercial license for
the Software. In that case, please contact the Author to inquire about
commercial licenses.

What are the rights given to noncommercial users? Similarly to GPL, you have the
right to use the software, to distribute copies, to receive source code, to
change the software and distribute your modifications or the modified software.
Also similarly to the GPL, if you distribute verbatim or modified copies of this
software, they must be distributed under this license.

By modeling the GPL, this license guarantees that you’re safe when using the
Software in your work, for teaching or research. This license guarantees that
the Software will remain available free of charge for nonprofit use. You can
modify the Software to your purposes, and you can also share your modifications.
Even in the unlikely case of the authors abandoning the Software entirely, this
license permits anyone to continue developing it from the last release, and to
create further releases under this license.

We believe that the combination of noncommercial open-source and commercial
licensing will be beneficial for the whole user community, because income from
commercial licenses will enable faster development and a higher level of
software quality, while further enjoying the informal, open communication and
collaboration channels of open source development.

The precise terms and conditions for using, copying, distribution and
modification follow.


TERMS AND CONDITIONS FOR USE, COPYING, DISTRIBUTION AND MODIFICATION

Definitions

“Program” means a copy of the Software, which is said to be distributed under
this Academic Public License.

“Work based on the Program” means either the Program or any derivative work
under copyright law: that is to say, a work containing the Program or a portion
of it, either verbatim or with modifications and/or translated into another
language. (Hereinafter, translation is included without limitation in the term
“modification”.)

“Using the Program” means any act of creating executables that contain or
directly use libraries that are part of the Program, running any of the tools
that are part of the Program, or creating works based on the Program.

Each licensee is addressed as “you”.

§1. Permission is hereby granted to use the Program free of charge for any
noncommercial purpose, including teaching and research at universities, colleges
and other educational institutions, research at non-profit research
institutions, and personal non-profit purposes. For using the Program for
commercial purposes, including but not restricted to consulting activities,
design of commercial hardware or software products, and a commercial entity
participating in research projects, you have to contact the Author for an
appropriate license. Permission is also granted to use the Program for a
reasonably limited period of time for the purpose of evaluating its usefulness
for a particular purpose.

§2. You may copy and distribute verbatim copies of the Program’s source code as
you receive it, in any medium, provided that you conspicuously and appropriately
publish on each copy an appropriate copyright notice and disclaimer of warranty;
keep intact all the notices that refer to this License and to the absence of any
warranty; and give any other recipients of the Program a copy of this License
along with the Program.

§3. You may modify your copy or copies of the Program or any portion of it, thus
forming a work based on the Program, and copy and distribute such modifications
or work under the terms of Section 2 above, provided that you also meet all of
these conditions:

a) You must cause the modified files to carry prominent notices stating that you
changed the files and the date of any change.

b) You must cause any work that you distribute or publish, that in whole or in
part contains or is derived from the Program or any part thereof, to be licensed
as a whole at no charge to all third parties under the terms of this License.

These requirements apply to the modified work as a whole. If identifiable
sections of that work are not derived from the Program, and can be reasonably
considered independent and separate works in themselves, then this License, and
its terms, do not apply to those sections when you distribute them as separate
works. But when you distribute the same sections as part of a whole which is a
work based on the Program, the distribution of the whole must be on the terms of
this License, whose regulations for other licensees extend to the entire whole,
and thus to each and every part regardless of who wrote it. (If the same,
independent sections are distributed as part of a package that is otherwise
reliant on, or is based on the Program, then the distribution of the whole
package, including but not restricted to the independent section, must be on the
unmodified terms of this License, regardless of who the author of the included
sections was.)

Thus, it is not the intent of this section to claim rights or contest your
rights to work written entirely by you; rather, the intent is to exercise the
right to control the distribution of derivative or collective works based or
reliant on the Program.

In addition, mere aggregation of another work not based on the Program with the
Program (or with a work based on the Program) on a volume of storage or
distribution medium does not bring the other work under the scope of this
License.

§4. You may copy and distribute the Program (or a work based on it, under
Section 3) in object code or executable form under the terms of Sections 2 and 3
above provided that you also do one of the following:

a) Accompany it with the complete corresponding machine-readable source code,
which must be distributed under the terms of Sections 2 and 3 above on a medium
customarily used for software interchange; or,

b) Accompany it with a written offer, valid for at least three years, to give
any third party, for a charge no more than your cost of physically performing
source distribution, a complete machine-readable copy of the corresponding
source code, to be distributed under the terms of Sections 2 and 3 above on a
medium customarily used for software interchange; or,

c) Accompany it with the information you received as to the offer to distribute
corresponding source code. (This alternative is allowed only for noncommercial
distribution and only if you received the program in object code or executable
form with such an offer, in accord with Subsection b) above.)

The source code for a work means the preferred form of the work for making
modifications to it. For an executable work, complete source code means all the
source code for all modules it contains, plus any associated interface
definition files, plus the scripts used to control compilation and installation
of the executable. However, as a special exception, the source code distributed
need not include anything that is normally distributed (in either source or
binary form) with the major components (compiler, kernel, and so on) of the
operating system on which the executable runs, unless that component itself
accompanies the executable.

If distribution of executable or object code is made by offering access to copy
from a designated place, then offering equivalent access to copy the source code
from the same place counts as distribution of the source code, even though third
parties are not compelled to copy the source along with the object code.

§5. You may not copy, modify, sublicense, or distribute the Program except as
expressly provided under this License. Any attempt otherwise to copy, modify,
sublicense or distribute the Program is void, and will automatically terminate
your rights under this License. However, parties who have received copies, or
rights, from you under this License will not have their licenses terminated so
long as such parties remain in full compliance.

§6. You are not required to accept this License, since you have not signed it.
Nothing else grants you permission to modify or distribute the Program or its
derivative works; law prohibits these actions if you do not accept this License.
Therefore, by modifying or distributing the Program (or any work based on the
Program), you indicate your acceptance of this License and all its terms and
conditions for copying, distributing or modifying the Program or works based on
it, to do so.

§7. Each time you redistribute the Program (or any work based on the Program),
the recipient automatically receives a license from the original licensor to
copy, distribute or modify the Program subject to these terms and conditions.
You may not impose any further restrictions on the recipients’ exercise of the
rights granted herein. You are not responsible for enforcing compliance by third
parties to this License.

§8. If, as a consequence of a court judgment or allegation of patent
infringement or for any other reason (not limited to patent issues), conditions
are imposed on you (whether by court order, agreement or otherwise) that
contradict the conditions of this License, they do not excuse you from the
conditions of this License. If you cannot distribute so as to satisfy
simultaneously your obligations under this License and any other pertinent
obligations, then as a consequence you may not distribute the Program at all.
For example, if a patent license would not permit royalty-free redistribution of
the Program by all those who receive copies directly or indirectly through you,
then the only way you could satisfy both it and this License would be to refrain
entirely from distribution of the Program.

If any portion of this section is held invalid or unenforceable under any
particular circumstance, the balance of the section is intended to apply and the
section as a whole is intended to apply in other circumstances.

§9. If the distribution and/or use of the Program are restricted in certain
countries either by patents or by copyrighted interfaces, the original copyright
holder who places the Program under this License may add an explicit
geographical distribution limitation excluding those countries, so that
distribution is permitted only in or among countries not thus excluded. In such
case, this License incorporates the limitation as if written in the body of this
License.


NO WARRANTY

§10. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY FOR
THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW. EXCEPT WHEN OTHERWISE
STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES PROVIDE THE PROGRAM
“AS IS” WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING,
BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A
PARTICULAR PURPOSE. THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE
PROGRAM IS WITH YOU. SHOULD THE PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF
ALL NECESSARY SERVICING, REPAIR OR CORRECTION.

§11. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED ON IN WRITING WILL
ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR REDISTRIBUTE THE
PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, INCLUDING ANY GENERAL,
SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING OUT OF THE USE OR INABILITY
TO USE THE PROGRAM INCLUDING BUT NOT LIMITED TO LOSS OF DATA OR DATA BEING
RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD PARTIES OR A FAILURE OF
THE PROGRAM TO OPERATE WITH ANY OTHER PROGRAMS), EVEN IF SUCH HOLDER OR OTHER
PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH DAMAGES.

§12. Further disclaimers: Without limiting the generality of the foregoing, the
following must also be considered and agreed to:

(a) Results may NOT be used in any legal documents. This is intended for general
data-analysis purposes ONLY!

(b) All results should be proofread by the user to ensure fidelity, due to
flaws, typos, and non-standardized abbreviations and formatting in the input
data, and possible bugs or limitations in the Software itself.

(c) The Software is able to account for many typos/abbreviations and formatting
differences. However, even if the input data is 'correctly' formatted (i.e.
accurately describes the correct lands), the Software may NOT capture every edge
case. The Software can generate warning flags and error flags for the user's
review (although depending on the specific implementation, the end user may not
have access to such flags). Regardless, the absence of such a flag or flags is
not conclusive proof that the output is correct and should not be construed as
such. Generally speaking, the cleaner and more standard the input data, the
better the output data.

(d) Finally, note that all of the example PLSS descriptions used in the comments
in the code and documentation are dummy data and were invented or arbitrarily
chosen. (Some are even nonsense.)
