                      ACADEMIC PUBLIC LICENSE

          Copyright (C) 2019, Felix Klein, Mark Santolucito

Preamble

This license contains the terms and conditions of using 'tsltools' 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 'tsltools' with
rights that are similar to the well-known GNU General Public License,
yet it retains the possibility for 'tsltools' authors to financially
support the development by selling commercial licenses. In fact, if
you intend to use 'tsltools' 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
'tsltools' to participate in a research project (for example
government-funded or EU-funded research projects), then you need to
obtain a commercial license for 'tsltools'. 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 'tsltools' in your work, for teaching or research. This license
guarantees that 'tsltools' will remain available free of charge for
nonprofit use. You can modify 'tsltools' to your purposes, and you can
also share your modifications. Even in the unlikely case of the
authors abandoning 'tsltools' 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 'tsltools', 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 networking 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, regadless 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.
