Paramotopy(TM) version 1.0 Authors: D.A. Brake, M.E. Niemerg, and D.J. Bates http://www.paramotopy.com Copyright (C) 2013 *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 Bertini software package, on which Paramotopy depends, has its own copyright and license. 0. Definitions "The Program" refers to any copyrightable work licensed under this license. Each licensee is addressed as "you" and may be any individual or an organization. "Paramotopy" refers to two executables, 'Paramotopy' and 'Step2', and all source code for each. 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 Paramotopy 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: Paramotopy(TM) version 1.0 Authors: D.A. Brake, M.E. Niemerg, and D.J. Bates 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 COLORADO. 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 COLORADO, 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 Paramotopy, directly or indirectly via a covered work, include an appropriate citation to Paramotopy, as stipulated on the Paramotopy website.
