*NOTICE*
|
|
|
|
This program is free software in that it is free to download (as source code or as a binary)
|
|
and free to use on the computer(s) to which it was downloaded. However, there are several
|
|
restrictions on its redistribution and its use in other programs, as indicated below.
|
|
|
|
The following software modules shipped with Bertini have their own copyright: the
|
|
GNU Multiple Precision Library (GMP) and the GNU MPFR Library (MPFR). This license covers
|
|
those parts of Bertini's source code written by the Authors, excluding these particular
|
|
modules. Copyrights and licenses for these modules have been included in the directory LICENSES.

0. Definitions
|
|
|
|
"The Program" refers to any copyrightable work licensed under this licence. Each licensee
|
|
is addressed as "you" and may be any individual or an organization.
|
|
|
|
To "modify" a work means to copy from or adapt all or part of the work in a fashion requiring
|
|
copyright permission, other than the making of an exact copy. The resulting work is called a
|
|
“modified version” of the earlier work or a work “based on” the earlier work.
|
|
|
|
To "propagate" a work means to do anything with it that, without permission, would make you
|
|
directly or secondarily liable for infringement under applicable copyright law, except executing
|
|
it on a computer or modifying a private copy. Propagation includes copying, distribution (with or
|
|
without modification), or making available to the public.
|
|
|
|
To "convey" a work means any kind of propagation that enables other parties to make or receive
|
|
copies. Mere interaction with a user through a computer network, with no transfer of a copy, is
|
|
not conveying.
|
|
|
|
A "Standard Interface" means an interface that either is an official standard defined by a
|
|
recognized standards body, or, in the case of interfaces specified for a particular programming
|
|
language, one that is widely used among developers working in that language.
|
|
|
|
A "covered work" means any work that in any way makes use of any part of the Program. This
|
|
includes, but is not restricted to, software that makes calls to any part of the Bertini
|
|
software package, in any form.
|
|
|
|
1. Basic Permissions.
|
|
|
|
All rights granted under this License are granted for the term of copyright on the Program,
|
|
and are irrevocable provided the stated conditions are met. This License explicitly affirms
|
|
your unlimited permission to run the unmodified Program.
|
|
|
|
2. Conveying Verbatim Copies.
|
|
|
|
You may convey 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; keep intact all notices stating that this License applies to the Program;
|
|
keep intact all notices of the absence of any warranty; and give all recipients a copy of
|
|
this License along with the Program.
|
|
|
|
You may not charge a fee for any copy that you convey, and you may not offer support or
|
|
warranty protection for a fee.
|
|
|
|
3. Conveying Modified Versions.
|
|
|
|
You may modify the Program for your private use only. You may not convey, in any manner, a
|
|
modified version of the Program without written consent of all Authors of the Program.
|
|
|
|
4. Conveying Covered Work.
|
|
|
|
The Program may be used in covered work. However, the following must be
|
|
displayed in the Standard Interface of the covered work:
|
|
|
|
Bertini(TM) version 1.4
|
|
Authors: D.J. Bates, J.D. Hauenstein, A.J. Sommese, C.W. Wampler
|
|
Copyright (C) 2013
|
|
|
|
Furthermore, if a covered work is conveyed, a verbatim copy of the Program's
|
|
source code must be conveyed simultaneously, as described in Section 2 of this License.
|
|
|
|
You may not charge a fee for any copy of any covered work without the written permission of
|
|
all Authors of the Program.
|
|
|
|
5. Termination.
|
|
|
|
You may not propagate, modify, or convey a covered work except as expressly provided under
|
|
this License. Any attempt otherwise to propagate, modify, or convey it will automatically
|
|
terminate your rights under this License.
|
|
|
|
6. No Surrender of Others' Freedom.
|
|
|
|
If 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 convey a covered work so as to satisfy simultaneously your obligations
|
|
under this License and any other pertinent obligations, then as a consequence you may not
|
|
convey it at all.
|
|
|
|
7. Disclaimer of Warranty.
|
|
|
|
THERE IS NO WARRANTY FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAWS OF
|
|
THE STATE OF INDIANA. 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.
|
|
|
|
8. Limitation of Liability
|
|
|
|
IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAWS OF THE STATE OF INDIANA, OR AGREED TO
|
|
IN WRITING, WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MODIFIES AND/OR CONVEYS 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.
|
|
|
|
9. Interpretation of Sections 7 and 8.
|
|
|
|
If the disclaimer of warranty and limitation of liability provided above cannot be given local
|
|
legal effect according to their terms, reviewing courts shall apply local law that most closely
|
|
approximates an absolute waiver of all civil liability in connection with the Program, unless a
|
|
warranty or assumption of liability accompanies a copy of the Program in return for a fee.
|
|
|
|
END OF TERMS AND CONDITIONS

|

|
|
directly or indirectly via a covered work, include an appropriate citation to Bertini, as
|
|
described on the website http://bertini.nd.edu/policy.html, or any future Bertini
|
