| = Ticket #8985: update COPYING.txt = See [[http://trac.sagemath.org/sage_trac/ticket/8985 | #8985]]. This file is about the copyright on Sage and all included components. Sage is a compilation both of original Python, C, C++, and Cython code, and of existing free mathematics-related software. All standard components of sage (those included in sage-*.tar) are licensed under a free open source license as defined at http://www.opensource.org/. Every component of Sage except jsmath is licensed under a GPL v2 (or later) compatible license. REMARK: jsmath is licensed under the Apache license which is GPL v3 compatible, but maybe not GPL v2 compatible. However, Sage doesn't have any link to jsmath -- we just distribute it as source code and users run it in their browser. Some of the code available in *optional* Sage packages (not included in sage-*.tar) are licensed under more restrictive conditions. * ORIGINAL SAGE LIBRARY CODE: All original Sage code is distributed under the terms of the GNU General Public License, either version 2 of the License, or (at your option) any later version. This code is distributed in the hope that it will be useful, but WITHOUT ANY WARRANTY; without even the implied warranty of MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the GNU General Public License for more details. The full text of the GPL is available below in this file. Details of the licenses of the components of Sage are included below as well. * LICENSES OF INCLUDED SOFTWARE: {{{ SOFTWARE LICENSE ---------------------------------------------- atlas Modified BSD (see below) blas boehm_gc Permissive BSD and GPL boost Boost Software License bzip2 BSD (customized) cddlib GPL cliquer GPL clisp GPL cvxopt GPL cython Apache License docutils Modified BSD ecl LGPL eclib GPL ecm LGPL gmp-ecm LGPL ellsea GPL extcode GPL f2c FIXME: unknown license flint GPL flintqs GPL fortran (G95) GPL freetype GPL gap GPL gd Custom (BSD-ish) gdmodule Custom (BSD-ish) genus2reduction GPL gfan GPL ghmm GPL givaro GPL gnuplotpy LGPL gnutls LGPL and GPL graphs FIXME: unknown license gsl GPL iconv GPL iml GPL, Modified BSD (see below) ipython Modified BSD jinja BSD jmol GPL (v2+) jsmath Apache License 2.0 (see note below) note: -- jsmath is never run by Sage or linked with Sage at runtime -- lapack New BSD lcalc (Rubinstein) GPL libfplll LGPL libgcrypt GPL libgpg_error GPL libm4ri GPL libpng libpng license linbox LGPL matplotlib Modified Python license maxima GPL mercurial GPL moinmoin wiki GPL mpfi GPL mpfr LGPL mpir LGPL mpmath New BSD License mwrank GPL networkx BSD ntl GPL numpy Modified BSD omalloc GPL (part of Singular; see below) opencdk GPL palp GPL pari GPL pexpect MIT (or X11) License pil BSD polybori GPL polytopes_db GPL pycrypto No restrictions pygments Modified BSD pynac GPL pyopenssl GPL pysqlite Modified BSD python Python License python_gnutls LGPL quaddouble Modified BSD R GPL ratpoints GPL readline GPL rubiks GPL and MIT sage GPL sage_scripts GPL sagenb GPL sagetex GPL scipy BSD scipy_sandbox comprising: ARPACK BSD-like delaunay BSD-style scons MIT (or X11) License setuptools Python Software Foundation License or Zope Public License simon-2descent GPL singular GPL sphinx Modified BSD sqlalchemy MIT sqlite Public Domain (no restrictions) symmetrica Public Domain as advertised on its website sympow Modified BSD sympy New BSD tachyon3d Modified BSD (see below) termcap GPL twisted Custom (Modified BSD) twistedweb2 MIT Free Software licence weave SciPy License (=Modified BSD) zlib Custom (Modified BSD) zodb3 ZPL }}} CONTACT INFO: William Stein; [email protected]; http://www.sagemath.org ========================================================================= GNU GENERAL PUBLIC LICENSE Version 2, June 1991 Copyright (C) 1989, 1991 Free Software Foundation, Inc. 51 Franklin St, Fifth Floor, Boston, MA 02110-1301 USA Everyone is permitted to copy and distribute verbatim copies of this license document, but changing it is not allowed. Preamble The licenses for most software are designed to take away your freedom to share and change it. By contrast, the GNU General Public License is intended to guarantee your freedom to share and change free software--to make sure the software is free for all its users. This General Public License applies to most of the Free Software Foundation's software and to any other program whose authors commit to using it. (Some other Free Software Foundation software is covered by the GNU Library General Public License instead.) You can apply it to your programs, too. When we speak of free software, we are referring to freedom, not price. Our General Public Licenses are designed to make sure that you have the freedom to distribute copies of free software (and charge for this service if you wish), that you receive source code or can get it if you want it, that you can change the software or use pieces of it in new free programs; and that you know you can do these things. To protect your rights, we need to make restrictions that forbid anyone to deny you these rights or to ask you to surrender the rights. These restrictions translate to certain responsibilities for you if you distribute copies of the software, or if you modify it. For example, if you distribute copies of such a program, whether gratis or for a fee, you must give the recipients all the rights that you have. You must make sure that they, too, receive or can get the source code. And you must show them these terms so they know their rights. We protect your rights with two steps: (1) copyright the software, and (2) offer you this license which gives you legal permission to copy, distribute and/or modify the software. Also, for each author's protection and ours, we want to make certain that everyone understands that there is no warranty for this free software. If the software is modified by someone else and passed on, we want its recipients to know that what they have is not the original, so that any problems introduced by others will not reflect on the original authors' reputations. Finally, any free program is threatened constantly by software patents. We wish to avoid the danger that redistributors of a free program will individually obtain patent licenses, in effect making the program proprietary. To prevent this, we have made it clear that any patent must be licensed for everyone's free use or not licensed at all. The precise terms and conditions for copying, distribution and modification follow. GNU GENERAL PUBLIC LICENSE TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION 0. 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 General 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, and the output from the Program is covered only if its contents constitute a work based on the Program (independent of having been made by running the Program). Whether that is true depends on what the Program does. 1. 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. 2. 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: a) You must cause the modified files to carry prominent notices stating that you changed the files and the date of any change. 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. 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.) 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. 3. 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: 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, 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, 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. 4. 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. 5. 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. 6. 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. 7. 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 the free software distribution system, which is implemented by 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. 8. 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. 9. The Free Software Foundation may publish revised and/or new versions of the General 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 Free Software Foundation. If the Program does not specify a version number of this License, you may choose any version ever published by the Free Software Foundation. 10. 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 Free Software Foundation, write to the Free Software Foundation; we sometimes make exceptions for this. Our decision will be guided by the two goals of preserving the free status of all derivatives of our free software and of promoting the sharing and reuse of software generally. NO WARRANTY 11. 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 PROGRAM 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 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. END OF TERMS AND CONDITIONS How to Apply These Terms to Your New Programs If you develop a new program, and you want it to be of the greatest possible use to the public, the best way to achieve this is to make it free software which everyone can redistribute and change under these terms. To do so, attach the following notices to the program. It is safest to attach them to the start of each source file to most effectively convey the exclusion of warranty; and each file should have at least the "copyright" line and a pointer to where the full notice is found. <one line to give the program's name and a brief idea of what it does.> Copyright (C) <year> <name of author> This program is free software; you can redistribute it and/or modify it under the terms of the GNU General Public License as published by the Free Software Foundation; either version 2 of the License, or (at your option) any later version. This program is distributed in the hope that it will be useful, but WITHOUT ANY WARRANTY; without even the implied warranty of MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the GNU General Public License for more details. You should have received a copy of the GNU General Public License along with this program; if not, write to the Free Software Foundation, Inc., 51 Franklin St, Fifth Floor, Boston, MA 02110-1301 USA Also add information on how to contact you by electronic and paper mail. If the program is interactive, make it output a short notice like this when it starts in an interactive mode: Gnomovision version 69, Copyright (C) year name of author Gnomovision comes with ABSOLUTELY NO WARRANTY; for details type `show w'. This is free software, and you are welcome to redistribute it under certain conditions; type `show c' for details. The hypothetical commands `show w' and `show c' should show the appropriate parts of the General Public License. Of course, the commands you use may be called something other than `show w' and `show c'; they could even be mouse-clicks or menu items--whatever suits your program. You should also get your employer (if you work as a programmer) or your school, if any, to sign a "copyright disclaimer" for the program, if necessary. Here is a sample; alter the names: Yoyodyne, Inc., hereby disclaims all copyright interest in the program `Gnomovision' (which makes passes at compilers) written by James Hacker. <signature of Ty Coon>, 1 April 1989 Ty Coon, President of Vice This General Public License does not permit incorporating your program into proprietary programs. If your program is a subroutine library, you may consider it more useful to permit linking proprietary applications with the library. If this is what you want to do, use the GNU Library General Public License instead of this License. ================================================================================ atlas: (http://math-atlas.sourceforge.net/) Automatically Tuned Linear Algebra Software v3.8.0 (C) Copyright 1998 R.

The Apache Software Foundation considers their license to be GPL v2 compatible... maybe, but the FSF evidently doesn't. Note that Sage doesn't *link* with jsmath. Sage only uses jsmath by sending it to a web browsers, which then run jsmath. I.e., the Sage program, which is a web server, at no point actually runs or uses jsmath to do anything. It is the web browser running on the client's computer that actually runs jsmath. Thus GPL compatibility of the jsmath license is not relevant to Sage. * From the Apache website: "It is the unofficial position of The Apache Software Foundation that the Apache license is compatible with the GPL. However, the Free Software Foundation holds a different position..." (http://www.apache.org/foundation/licence-FAQ.html#GPL), and the FSF writes (http://www.fsf.org/licensing/licenses/index_html) "This is a free software license but it is incompatible with the GPL. The Apache Software License is incompatible with the GPL because it has a specific requirement that is not in the GPL: it has certain patent termination cases that the GPL does not require. (We don't think those patent termination cases are inherently a bad idea, but nonetheless they are incompatible with the GNU GPL.)" ================================================================================ Lcalc: (http://pmmac03.math.uwaterloo.ca/~mrubinst/L_function_public/CODE/) copyright Michael Rubinstein Lcalc is distributed under the GNU GPL. ================================================================================ matplotlib: LICENSE AGREEMENT FOR MATPLOTLIB 0.90.0 -------------------------------------- 1.

Schelter. On 6 October 1998 William F. Schelter was formally notified that he could distribute DOE-MACSYMA upon terms of his choosing, in particular the GNU General Public License: <http://www.ma.utexas.edu/users/wfs/maxima-doe-auth.gif> Schelter proceed to distribute derived works under the GPL. In the formal notification a request was made that a paragraph "should be included in the GPL and should accompany other modifications, enhancements or derivative works of your program." This paragraph is transcribed below in honor of that request. Like the preamble it does not form part of the license. "Distribution of such derivative works is subject to the U.S. Export Administration Regulations (Title 15 CFR 768-799), which implements the Export Administration Act of 1979, as amended, and/or the International Traffic in Arms Regulations, of 12-6-84, (Title 22 CFR 121-130), which implements the Arms Export Control Act (22 U.S.C. 2728) and may require license for export." ================================================================================ MPFR: (http://www.mpfr.org/) MPFR is free. It is distributed under the GNU Lesser General Public License (GNU Lesser GPL). The library has been registered in France by the Agence de Protection des Programmes under the number IDDN FR 001 120020 00 R P 2000 000 10800, on 15 March 2000. This license guarantees your freedom to share and change MPFR, to make sure MPFR is free for all its users. Unlike the ordinary General Public License, the Lesser GPL enables developers of non-free programs to use MPFR in their programs. If you have written a new function for MPFR or improved an existing one, please share your work! ================================================================================ mwrank: (http://www.maths.nott.ac.uk/personal/jec/ftp/progs/) copyright John Cremona Mwrank is released under the GNU General Public License. ================================================================================ NTL: (http://www.shoup.net/ntl/) A Library for Doing Number Theory Copyright (C) 1996-2005 Victor Shoup The most recent version of NTL is available at http://www.shoup.net This program is free software; you can redistribute it and/or modify it under the terms of the GNU General Public License as published by the Free Software Foundation; either version 2 of the License, or (at your option) any later version.

All code authors, and representatives of the companies they work for, have signed affidavits dedicating their contributions to the public domain and originals of those signed affidavits are stored in a firesafe at the main offices of Hwaci. Anyone is free to copy, modify, publish, use, compile, sell, or distribute the original SQLite code, either in source code form or as a compiled binary, for any purpose, commercial or non-commercial, and by any means. The previous paragraph applies to the deliverable code in SQLite - those parts of the SQLite library that you actually bundle and ship with a larger application. Portions of the documentation and some code used as part of the build process might fall under other licenses. The details here are unclear. We do not worry about the licensing of the documentation and build code so much because none of these things are part of the core deliverable SQLite library. All of the deliverable code in SQLite has been written from scratch. No code has been taken from other projects or from the open internet. Every line of code can be traced back to its original author, and all of those authors have public domain dedications on file. So the SQLite code base is clean and is uncontaminated with licensed code from other projects. ================================================================================ sympow: (http://www.maths.bris.ac.uk/~mamjw/) copyright Mark Watkins.

This license seeks to allow free use of Zope and its source given a few conditions for use. Our goals are to allow Zope to flourish as an open source project while making sure that we get some credit for having originally developed Zope. The 2.1 version of the license is reusable. It supports having a consistent license for Zope and third-party products without requiring 3rd-party developers to assign copyright to Zope Corporation. It is important that add-on products for Zope be released under the ZPL. Why? Two reasons: * The ZPL is a flexible license that supports both commercial and non-commercial use of the software. * If Zope add-on products are released under the ZPL, then users of Zope and the add-on products only have one license to worry about. Keeping track of many different licenses is a burden to users. Software can be released under multiple licenses. For example, software can be released under both the ZPL and the GPL. We will update the Zope software to use ZPL 2.1. This does not change the rules for contributing to the Zope software repository. Contributions to the Zope repository will still be owned by "Zope Corporation and Contributors". To use the ZPL 2.1 license, just include the license with your software and also include a separate copyright statement (sample). We have updated to the 2.1 version. The license though, like Zope itself, is a work-in-progress. We would love to hear your ideas on the license. Please send your comments on the license to [email protected]. This license has received OSD branding. Zope Corporation is working to stay true to the spirit of the Open Source Definition and its stated rationales. This license has been confirmed as GPL compatible by the FSF. ================================================================================ |
