International AVS Center License Agreement, version 1.0 Copyright (C) 1991 International AVS Center 3021 Cornwallis Road RTP, NC 27709, USA INTRODUCTION The International AVS Center license applies to all modules and associated code, data, networks, scripts and other information located in the anonymous ftp site set up and maintained by the International AVS Center at ftp host avs.ncsc.org (128.109.178.23). Reference to this license is made in all areas where the Warrantee Disclaimer appears. Data files , binaries and other forms where it is not appropriate for this disclaimer to appear are still bound by the conditions of this license if they were obtained from the International AVS Center and this license agreement must accompany said items. If the author gives written permission, or you obtain modules from an alternative source that was not distributed from the International AVS Center or anyone who distributed from that point, such as the SLATEC repository, then you are bound only by the rules of that repository or author copyright. Otherwise the terms of this license must be adhered to unless you receive written permission from the International AVS Center for these special circumstances. Since the purpose of the license is to protect donors of AVS modules and not make the terms too difficult to abide by, the International AVS Center will work closely with any group that needs these special permissions (i.e. government labs) to alter conditions of the license so that they can be used by these groups. The Center will coordinate with authors/donors to get approvals as quickly as possible. You are free to use, modify, give away or sell all modules and associated files subject to the conditions of the Warranty Disclaimer, associated copyrights and the terms of this license agreement as laid out below. If you give away or sell modules or any associated files you must provide source code or make source code available upon request for all modules and associated files that were obtained from the International AVS Center, unless otherwise specified by written agreement from the International AVS Center. You must pass this license and all the rights that it implies along with any distribution of modules or associated files. These rights and restrictions are binding upon all distributions of the files. The International AVS Center wants to ensure that all parties understand that there is no warranty for modules or associated files obtained from the International AVS Center by any method. If you modify and distribute files you must include a statement in the header ( or a readme file for data, binaries, etc) that states that the file has been modified and is not the original so that any problems introduced will not reflect upon the original authors. TERMS AND CONDITIONS FOR COPYING, MODIFYING AND DISTRIBUTION 1. This license agreement applies to any file obtained from the International AVS Center, unless written permission is obtained from the International AVS Center. The word "module" will henceforth refer to any file ( module, network, script, data, etc ) that is obtained from the International AVS Center. This license must accompany all distributions of modules whether original or modified. "You" refers to the individuals who either obtain the modules or use the modules. 2. You may copy and distribute original copies of modules in any medium provided you conspicuously and appropriately include this license agreement, keep intact all notices, warrantee disclaimer, author credits, version information and copyright notices. You may charge a fee for the physical act of transferring a copy. 3. You may modify your copy or copies of modules or any portion of these modules and distribute such modifications provided you also do the following: a. ensure that the modified modules carry a notice stating that you changed the original code, your name, date and how you can be contacted. In cases where the module is data or a file where this is not appropriate you will provide a readme file with this information. b. cause the whole or part of any work that you distribute or publish, that in whole or in part contains the modules or any part thereof, either with or without modifications, to be licensed at no charge to all third parties under the terms of this International AVS Center license ( except that you may choose to grant warrantee protection to some or all third parties, at your option and your risk). c. 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. 4. Mere aggregation of another independent work with the module ( or its derivative) on a volume of storage or distribution medium does not bring the other work under the scope of these terms. 5. You may copy and distribute the module or a portion or derivative of it in object code or executable form under the terms listed above provided you do one of the following: a. accompany it with the complete corresponding machine readable source code, which must be distributed under the terms listed above; or, b. accompany it with a written offer, valid for at least one year, to give any third party free ( exception for nominal distribution fee) a complete machine readable copy of the corresponding source code; or, c. accompany it with the information you received as to where the corresponding source code may be obtained. This alternative is allowed only for noncommercial distribution and only if you received the module in object code or executable form alone. 6. You may not copy, modify, sublicense, distribute or transfer the modules except as expressly provided in this license without written permission from the International AVS Center. Any attempt otherwise to copy, modify, sublicense, distribute or transfer the modules is void, and will make you liable for legal action by the International AVS Center, the module author, the AVS Consortium or AVS vendors as appropriate. It will also automatically terminate your right to use the module under this license. However, parties who have received copies, or rights to use copies, from you under this AVS license agreement will not have their use of the modules revoked so long as such parties remain in full compliance with the terms outlined in this license. 7. By copying, distributing or otherwise modifying modules or any work based on the modules, you indicate your acceptance of this license along with all of its terms and conditions. 8. Each time you redistribute the modules or any modification thereof, you must include this license and you may not impose further restrictions on the recipients exercise of the rights granted herein. The individual who receives your distribution must agree to these terms also. 9. The International AVS Center may publish revised and/or new versions of this original AVS license from time to time. Each version will be given a unique version number of the license which applies to it and "any later versions". You have the option of following the terms and conditions outlined in the version you receive at the time you receive the module or any later version. If the module does not specify the version, you may choose any version published by the International AVS Center for module licensing. 10. If you wish to incorporate parts of the program into other free software whose distribution conditions are different, write to the author or the International AVS Center to obtain permission. 11. BECAUSE THESE MODULES ARE OFFERED FREE OF CHARGE, THERE IS NO WARRANTY FOR THE MODULE, TO THE EXTENT PERMITTED BY APPLICABLE LAW. EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES PROVIDE THE MODULE "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 MODULE. THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE MODULE IS WITH YOU. SHOULD THE MODULE PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING, REPAIR OR CORRECTION. 12. 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 MODULE AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES ARISING OUT OF THE USE OR INABILITY TO USE THE MODULE ( 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 MODULE TO OPERATE WITH ANY OTHER MODULES OR PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH DAMAGES.
