Jabber-Net, Copyright (c) 2002-2004 Cursive Systems, Inc. All Rights Reserved. Contact information for Cursive Systems, Inc. is available at http://www.cursive.net/. Jabber-Net can be used under either of two licenses. The Jabber Open Source License (JOSL) is probably most appropriate for corporate use. http://www.jabber.org/about/josl.php The GNU Public License (GPL) is probably most appropriate for inclusion in other open source projects. http://www.gnu.org/copyleft/gpl.html I ask that you don't use this library to build an entire commercial Jabber/XMPP server. There's no legal restriction against it, just common courtesy, since my day job depends on selling servers. This file MUST be included with any source distribution. JOSL ------------------------------------------------------------------ Preamble This Preamble is intended to describe, in plain English, the nature and scope of this License. However, this Preamble is not a part of this license. The legal effect of this License is dependent only upon the terms of the License and not this Preamble. This License complies with the Open Source Definition and has been approved by Open Source Initiative. Software distributed under this License may be marked as "OSI Certified Open Source Software." This License provides that: 1. You may use, sell or give away the Licensed Product, alone or as a component of an aggregate software distribution containing programs from several different sources. No royalty or other fee is required. 2. Both Source Code and executable versions of the Licensed Product, including Modifications made by previous Contributors, are available for your use. (The terms "Licensed Product," "Modifications," "Contributors" and "Source Code" are defined in the License.) 3. You are allowed to make Modifications to the Licensed Product, and you can create Derivative Works from it. (The term "Derivative Works" is defined in the License.) 4. By accepting the Licensed Product under the provisions of this License, you agree that any Modifications you make to the Licensed Product and then distribute are governed by the provisions of this License. In particular, you must make the Source Code of your Modifications available to others. 5. You may use the Licensed Product for any purpose, but the Licensor is not providing you any warranty whatsoever, nor is the Licensor accepting any liability in the event that the Licensed Product doesn't work properly or causes you any injury or damages. 6. If you sublicense the Licensed Product or Derivative Works, you may charge fees for warranty or support, or for accepting indemnity or liability obligations to your customers. You cannot charge for the Source Code. 7. If you assert any patent claims against the Licensor relating to the Licensed Product, or if you breach any terms of the License, your rights to the Licensed Product under this License automatically terminate. You may use this License to distribute your own Derivative Works, in which case the provisions of this License will apply to your Derivative Works just as they do to the original Licensed Product. Alternatively, you may distribute your Derivative Works under any other OSI-approved Open Source license, or under a proprietary license of your choice. If you use any license other than this License, however, you must continue to fulfill the requirements of this License (including the provisions relating to publishing the Source Code) for those portions of your Derivative Works that consist of the Licensed Product, including the files containing Modifications. New versions of this License may be published from time to time. You may choose to continue to use the license terms in this version of the License or those from the new version. However, only the Licensor has the right to change the License terms as they apply to the Licensed Product. This License relies on precise definitions for certain terms. Those terms are defined when they are first used, and the definitions are repeated for your convenience in a Glossary at the end of the License. License Terms 1. Grant of License From Licensor. Licensor hereby grants you a world-wide, royalty-free, non-exclusive license, subject to third party intellectual property claims, to do the following: a. Use, reproduce, modify, display, perform, sublicense and distribute Licensed Product or portions thereof (including Modifications as hereinafter defined), in both Source Code or as an executable program. "Source Code" means the preferred form for making modifications to the Licensed Product, including all modules contained therein, plus any associated interface definition files, scripts used to control compilation and installation of an executable program, or a list of differential comparisons against the Source Code of the Licensed Product. b. Create Derivative Works (as that term is defined under U.S. copyright law) of Licensed Product by adding to or deleting from the substance or structure of said Licensed Product. c. Under claims of patents now or hereafter owned or controlled by Licensor, to make, use, sell, offer for sale, have made, and/or otherwise dispose of Licensed Product or portions thereof, but solely to the extent that any such claim is necessary to enable you to make, use, sell, offer for sale, have made, and/or otherwise dispose of Licensed Product or portions thereof or Derivative Works thereof. 2. Grant of License to Modifications From Contributor. "Modifications" means any additions to or deletions from the substance or structure of (i) a file containing Licensed Product, or (ii) any new file that contains any part of Licensed Product. Hereinafter in this License, the term "Licensed Product" shall include all previous Modifications that you receive from any Contributor. By application of the provisions in Section 4(a) below, each person or entity who created or contributed to the creation of, and distributed, a Modification (a "Contributor") hereby grants you a world-wide, royalty-free, non-exclusive license, subject to third party intellectual property claims, to do the following: a. Use, reproduce, modify, display, perform, sublicense and distribute any Modifications created by such Contributor or portions thereof, in both Source Code or as an executable program, either on an unmodified basis or as part of Derivative Works. b. Under claims of patents now or hereafter owned or controlled by Contributor, to make, use, sell, offer for sale, have made, and/or otherwise dispose of Modifications or portions thereof, but solely to the extent that any such claim is necessary to enable you to make, use, sell, offer for sale, have made, and/or otherwise dispose of Modifications or portions thereof or Derivative Works thereof. 3. Exclusions From License Grant. Nothing in this License shall be deemed to grant any rights to trademarks, copyrights, patents, trade secrets or any other intellectual property of Licensor or any Contributor except as expressly stated herein. No patent license is granted separate from the Licensed Product, for code that you delete from the Licensed Product, or for combinations of the Licensed Product with other software or hardware. No right is granted to the trademarks of Licensor or any Contributor even if such marks are included in the Licensed Product. Nothing in this License shall be interpreted to prohibit Licensor from licensing under different terms from this License any code that Licensor otherwise would have a right to license. 4. Your Obligations Regarding Distribution. a. Application of This License to Your Modifications. As an express condition for your use of the Licensed Product, you hereby agree that any Modifications that you create or to which you contribute, and which you distribute, are governed by the terms of this License including, without limitation, Section 2. Any Modifications that you create or to which you contribute may be distributed only under the terms of this License or a future version of this License released under Section 7. You must include a copy of this License with every copy of the Modifications you distribute. You agree not to offer or impose any terms on any Source Code or executable version of the Licensed Product or Modifications that alter or restrict the applicable version of this License or the recipients' rights hereunder. However, you may include an additional document offering the additional rights described in Section 4(e). b. Availability of Source Code. You must make available, under the terms of this License, the Source Code of the Licensed Product and any Modifications that you distribute, either on the same media as you distribute any executable or other form of the Licensed Product, or via a mechanism generally accepted in the software development community for the electronic transfer of data (an "Electronic Distribution Mechanism"). The Source Code for any version of Licensed Product or Modifications that you distribute must remain available for at least twelve (12) months after the date it initially became available, or at least six (6) months after a subsequent version of said Licensed Product or Modifications has been made available. You are responsible for ensuring that the Source Code version remains available even if the Electronic Distribution Mechanism is maintained by a third party. c. Description of Modifications. You must cause any Modifications that you create or to which you contribute, and which you distribute, to contain a file documenting the additions, changes or deletions you made to create or contribute to those Modifications, and the dates of any such additions, changes or deletions. You must include a prominent statement that the Modifications are derived, directly or indirectly, from the Licensed Product and include the names of the Licensor and any Contributor to the Licensed Product in (i) the Source Code and (ii) in any notice displayed by a version of the Licensed Product you distribute or in related documentation in which you describe the origin or ownership of the Licensed Product. You may not modify or delete any preexisting copyright notices in the Licensed Product. d. Intellectual Property Matters. i. Third Party Claims. If you have knowledge that a license to a third party's intellectual property right is required to exercise the rights granted by this License, you must include a text file with the Source Code distribution titled "LEGAL" that describes the claim and the party making the claim in sufficient detail that a recipient will know whom to contact. If you obtain such knowledge after you make any Modifications available as described in Section 4(b), you shall promptly modify the LEGAL file in all copies you make available thereafter and shall take other steps (such as notifying appropriate mailing lists or newsgroups) reasonably calculated to inform those who received the Licensed Product from you that new knowledge has been obtained. ii. Contributor APIs. If your Modifications include an application programming interface ("API") and you have knowledge of patent licenses that are reasonably necessary to implement that API, you must also include this information in the LEGAL file. iii. Representations. You represent that, except as disclosed pursuant to 4(d)(i) above, you believe that any Modifications you distribute are your original creations and that you have sufficient rights to grant the rights conveyed by this License. e. Required Notices. You must duplicate this License in any documentation you provide along with the Source Code of any Modifications you create or to which you contribute, and which you distribute, wherever you describe recipients' rights relating to Licensed Product. You must duplicate the notice contained in Exhibit A (the "Notice") in each file of the Source Code of any copy you distribute of the Licensed Product. If you created a Modification, you may add your name as a Contributor to the Notice. If it is not possible to put the Notice in a particular Source Code file due to its structure, then you must include such Notice in a location (such as a relevant directory file) where a user would be likely to look for such a notice. You may choose to offer, and charge a fee for, warranty, support, indemnity or liability obligations to one or more recipients of Licensed Product. However, you may do so only on your own behalf, and not on behalf of the Licensor or any Contributor. You must make it clear that any such warranty, support, indemnity or liability obligation is offered by you alone, and you hereby agree to indemnify the Licensor and every Contributor for any liability incurred by the Licensor or such Contributor as a result of warranty, support, indemnity or liability terms you offer. f. Distribution of Executable Versions. You may distribute Licensed Product as an executable program under a license of your choice that may contain terms different from this License provided (i) you have satisfied the requirements of Sections 4(a) through 4(e) for that distribution, (ii) you include a conspicuous notice in the executable version, related documentation and collateral materials stating that the Source Code version of the Licensed Product is available under the terms of this License, including a description of how and where you have fulfilled the obligations of Section 4(b), (iii) you retain all existing copyright notices in the Licensed Product, and (iv) you make it clear that any terms that differ from this License are offered by you alone, not by Licensor or any Contributor. You hereby agree to indemnify the Licensor and every Contributor for any liability incurred by Licensor or such Contributor as a result of any terms you offer. g. Distribution of Derivative Works. You may create Derivative Works (e.g., combinations of some or all of the Licensed Product with other code) and distribute the Derivative Works as products under any other license you select, with the proviso that the requirements of this License are fulfilled for those portions of the Derivative Works that consist of the Licensed Product or any Modifications thereto. 5. Inability to Comply Due to Statute or Regulation. If it is impossible for you to comply with any of the terms of this License with respect to some or all of the Licensed Product due to statute, judicial order, or regulation, then you must (i) comply with the terms of this License to the maximum extent possible, (ii) cite the statute or regulation that prohibits you from adhering to the License, and (iii) describe the limitations and the code they affect. Such description must be included in the LEGAL file described in Section 4(d), and must be included with all distributions of the Source Code. Except to the extent prohibited by statute or regulation, such description must be sufficiently detailed for a recipient of ordinary skill at computer programming to be able to understand it. 6. Application of This License. This License applies to code to which Licensor or Contributor has attached the Notice in Exhibit A, which is incorporated herein by this reference. 7. Versions of This License. a. New Versions. Licensor may publish from time to time revised and/or new versions of the License. b. Effect of New Versions. Once Licensed Product has been published under a particular version of the License, you may always continue to use it under the terms of that version. You may also choose to use such Licensed Product under the terms of any subsequent version of the License published by Licensor. No one other than Lic ensor has the right to modify the terms applicable to Licensed Product created under this License. c. Derivative Works of this License. If you create or use a modified version of this License, which you may do only in order to apply it to software that is not already a Licensed Product under this License, you must rename your license so that it is not confusingly similar to this License, and must make it clear that your license contains terms that differ from this License. In so naming your license, you may not use any trademark of Licensor or any Contributor. 8. Disclaimer of Warranty. LICENSED PRODUCT IS PROVIDED UNDER THIS LICENSE ON AN "AS IS" BASIS, WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESS OR IMPLIED, INCLUDING, WITHOUT LIMITATION, WARRANTIES THAT THE LICENSED PRODUCT IS FREE OF DEFECTS, MERCHANTABLE, FIT FOR A PARTICULAR PURPOSE OR NON-INFRINGING. THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE LICENSED PRODUCT IS WITH YOU. SHOULD LICENSED PRODUCT PROVE DEFECTIVE IN ANY RESPECT, YOU (AND NOT THE LICENSOR OR ANY OTHER CONTRIBUTOR) ASSUME THE COST OF ANY NECESSARY SERVICING, REPAIR OR CORRECTION. THIS DISCLAIMER OF WARRANTY CONSTITUTES AN ESSENTIAL PART OF THIS LICENSE. NO USE OF LICENSED PRODUCT IS AUTHORIZED HEREUNDER EXCEPT UNDER THIS DISCLAIMER. 9. Termination. a. Automatic Termination Upon Breach. This license and the rights granted hereunder will terminate automatically if you fail to comply with the terms herein and fail to cure such breach within thirty (30) days of becoming aware of the breach. All sublicenses to the Licensed Product that are properly granted shall survive any termination of this license. Provisions that, by their nature, must remain in effect beyond the termination of this License, shall survive. b. Termination Upon Assertion of Patent Infringement. If you initiate litigation by asserting a patent infringement claim (excluding declaratory judgment actions) against Licensor or a Contributor (Licensor or Contributor against whom you file such an action is referred to herein as "Respondent") alleging that Licensed Product directly or indirectly infringes any patent, then any and all rights granted by such Respondent to you under Sections 1 or 2 of this License shall terminate prospectively upon sixty (60) days notice from Respondent (the "Notice Period") unless within that Notice Period you either agree in writing (i) to pay Respondent a mutually agreeable reasonably royalty for your past or future use of Licensed Product made by such Respondent, or (ii) withdraw your litigation claim with respect to Licensed Product against such Respondent. If within said Notice Period a reasonable royalty and payment arrangement are not mutually agreed upon in writing by the parties or the litigation claim is not withdrawn, the rights granted by Licensor to you under Sections 1 and 2 automatically terminate at the expiration of said Notice Period. c. Reasonable Value of This License. If you assert a patent infringement claim against Respondent alleging that Licensed Product directly or indirectly infringes any patent where such claim is resolved (such as by license or settlement) prior to the initiation of patent infringement litigation, then the reasonable value of the licenses granted by said Respondent under Sections 1 and 2 shall be taken into account in determining the amount or value of any payment or license. d. No Retroactive Effect of Termination. In the event of termination under Sections 9(a) or 9(b) above, all end user license agreements (excluding licenses to distributors and reselle rs) that have been validly granted by you or any distributor hereunder prior to termination shall survive termination. 10. Limitation of Liability. UNDER NO CIRCUMSTANCES AND UNDER NO LEGAL THEORY, WHETHER TORT (INCLUDING NEGLIGENCE), CONTRACT, OR OTHERWISE, SHALL THE LICENSOR, ANY CONTRIBUTOR, OR ANY DISTRIBUTOR OF LICENSED PRODUCT, OR ANY SUPPLIER OF ANY OF SUCH PARTIES, BE LIABLE TO ANY PERSON FOR ANY INDIRECT, SPECIAL, INCIDENTAL, OR CONSEQUENTIAL DAMAGES OF ANY CHARACTER INCLUDING, WITHOUT LIMITATION, DAMAGES FOR LOSS OF GOODWILL, WORK STOPPAGE, COMPUTER FAILURE OR MALFUNCTION, OR ANY AND ALL OTHER COMMERCIAL DAMAGES OR LOSSES, EVEN IF SUCH PARTY SHALL HAVE BEEN INFORMED OF THE POSSIBILITY OF SUCH DAMAGES. THIS LIMITATION OF LIABILITY SHALL NOT APPLY TO LIABILITY FOR DEATH OR PERSONAL INJURY RESULTING FROM SUCH PARTYÕS NEGLIGENCE TO THE EXTENT APPLICABLE LAW PROHIBITS SUCH LIMITATION. SOME JURISDICTIONS DO NOT ALLOW THE EXCLUSION OR LIMITATION OF INCIDENTAL OR CONSEQUENTIAL DAMAGES, SO THIS EXCLUSION AND LIMITATION MAY NOT APPLY TO YOU. 11. Responsibility for Claims. As between Licensor and Contributors, each party is responsible for claims and damages arising, directly or indirectly, out of its utilization of rights under this License. You agree to work with Licensor and Contributors to distribute such responsibility on an equitable basis. Nothing herein is intended or shall be deemed to constitute any admission of liability. 12. U.S. Government End Users. The Licensed Product is a "commercial item," as that term is defined in 48 C.F.R. 2.101 (Oct. 1995), consisting of "commercial computer software" and "commercial computer software documentation," as such terms are used in 48 C.F.R. 12.212 (Sept. 1995). Consistent with 48 C.F.R. 12.212 and 48 C.F.R. 227.7202-1 through 227.7202-4 (June 1995), all U.S. Government End Users acquire Licensed Product with only those rights set forth herein. 13. Miscellaneous. This License represents the complete agreement concerning the subject matter hereof. If any provision of this License is held to be unenforceable, such provision shall be reformed only to the extent necessary to make it enforceable. This License shall be governed by California law provisions (except to the extent applicable law, if any, provides otherwise), excluding its conflict-of-law provisions. You expressly agree that any litigation relating to this license shall be subject to the jurisdiction of the Federal Courts of the Northern District of California or the Superior Court of the County of Santa Clara, California (as appropriate), with venue lying in Santa Clara County, California, with the losing party responsible for costs including, without limitation, court costs and reasonable attorneys' fees and expenses. The application of the United Nations Convention on Contracts for the International Sale of Goods is expressly excluded. You and Licensor expressly waive any rights to a jury trial in any litigation concerning Licensed Product or this License. Any law or regulation that provides that the language of a contract shall be construed against the drafter shall not apply to this License. 14. Definition of "You" in This License. "You" throughout this License, whether in upper or lower case, means an individual or a legal entity exercising rights under, and complying with all of the terms of, this License or a future version of this License issued under Section 7. For legal entities, "you" includes any entity that controls, is controlled by, or is under common control with you. For purposes of this definition, "control" means (i) the power, direct or indirect, to cause the direction or management of such entity, whether by contract or otherwise, or (ii) ownership of fifty percent (50%) or more of the outstanding shares, or (iii) beneficial ownership of such entity. 15.

GPL ------------------------------------------------------------------ GNU GENERAL PUBLIC LICENSE Version 2, June 1991 Copyright (C) 1989, 1991 Free Software Foundation, Inc. 59 Temple Place, Suite 330, Boston, MA 02111-1307 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., 59 Temple Place, Suite 330, Boston, MA 02111-1307 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.
