Boehm CSSE Limited Public License
Terms and Conditions

The precise terms and conditions for copying, distribution, and modification are as follows:

1) This License applies to any program or other work which contains a notice placed by the
copyright holder saying it may be distributed under the terms of this Limited Public
License. The “Program”, below, refers to any such program or work, and a “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”.) Each licensee is addressed as
“you”.

Activities other than copying, distribution and modification are not covered by this License; they are outside its scope. The act of running the Program is not restricted nor is the output from the Program is covered.

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.

You may charge a fee for the physical act of transferring a copy, and you may at your
option offer warranty protection in exchange for a fee.

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 1 above, provided that you also meet all of these conditions:

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

3.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.

3.c) If the modified program normally reads commands interactively when run, you must cause it, when started running for such interactive use in the most ordinary way, to print or
display an announcement including an appropriate copyright notice and a notice that there
is no warranty (or else, saying that you provide a warranty) and that users may
redistribute the program under these conditions, and telling the user how to view a copy of
this License. (Exception: if the Program itself is interactive but does not normally print
such an announcement, your work based on the Program is not required to print an
announcement.)

3.d) You must provide a copy of the modified machine-readable source code files to the
Boehm Center for Systems and Software Engineering on an appropriate medium or
via our contact information at info@boehmboehm.org
.

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 permissions for other licensees extend to
the entire whole, and thus to each and every part regardless of who wrote it.

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 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 a 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 2) in
object code or executable form under the terms of Sections 1 and 2 above provided that you
also do one of the following:

4.a) Accompany it with the complete corresponding machine-readable source code, which must
be distributed under the terms of Sections 1 and 2 above on a medium customarily used for
software interchange; or,

4.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 1 and 2 above on a medium customarily used for software interchange;
or,

4.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. However,
nothing else grants you permission to modify or distribute the Program or its derivative
works. These actions are prohibited by law 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 to do so, and all its terms and conditions for copying,
distributing or modifying the Program or works based on it.

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.

It is not the purpose of this section to induce you to infringe any patents or other
property right claims or to contest validity of any such claims; this section has the sole
purpose of protecting the integrity of this free software with limitations distribution
system, which is implemented by limited public license practices. Many people have made
generous contributions to the wide range of software distributed through that system in
reliance on consistent application of that system; it is up to the author/donor to decide
if he or she is willing to distribute software through any other system and a licensee
cannot impose that choice.

This section is intended to make thoroughly clear what is believed to be a consequence of
the rest of this License.

9) If the distribution and/or use of the Program is 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.

10) The Boehm Center for Systems and Software Engineering may publish revised and/or new versions of this Limited Public License from time to time. Such new versions will be similar in spirit to the present version, but may differ in detail to address new problems or concerns.

Each version is given a distinguishing version number. If the Program specifies a version
number of this License which applies to it and “any later version”, you have the option of
following the terms and conditions either of that version or of any later version published
by the University of Southern California Center for Systems and Software Engineering. If the Program does not specify a version number of this License, you may choose any version ever
published by the Boehm Center for Systems and Software Engineering.

11) If you wish to incorporate parts of the Program into other free programs whose
distribution conditions are different, write to the author to ask for permission. For
software which is copyrighted by the Boehm Center for Software Engineering, write to the Boehm Center for Systems and Software Engineering (info@barryboehm.org); we sometimes make exceptions for this. Our decision will be guided by the goal of preserving the free status of all derivatives of our free software with limitations.

No Warranty

12) 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 ROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING, REPAIR OR CORRECTION.

13) IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO 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.
