| *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 |
| |
| In addition to the stated license, we ask that any publications which made use of Bertini, |
| 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 |
| page created by the Authors. |
