| <B>The GNU General Public License |
| <P></P> |
| </B>Version 2, June 1991 |
| <P></P> |
| Copyright © 1989, 1991 Free Software Foundation, Inc. |
| <BR>59 Temple Place / Suite 330, Boston, MA 02111-1307, USA |
| <P></P> |
| Everyone is permitted to copy and distribute verbatim copies of this license |
| document, but changing it is not allowed. |
| <P></P> |
| <B>Preamble |
| <P></P> |
| </B>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. |
| <P></P> |
| 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. |
| <P></P> |
| 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. |
| <P></P> |
| 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. |
| <P></P> |
| 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. |
| <P></P> |
| 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. |
| <P></P> |
| 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. |
| <P></P> |
| <B>TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION |
| <P></P> |
| </B>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'. |
| <P></P> |
| 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. |
| <P></P> |
| <OL><LI> 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. |
| <P></P> |
| </OL>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. |
| <P></P> |
| <OL START="2"><LI> 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: |
| <P></P> |
| </OL>a) You must cause the modified files to carry prominent notices stating that you |
| changed the files and the date of any change. |
| <P></P> |
| 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. |
| <P></P> |
| 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.) |
| <P></P> |
| 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. |
| <P></P> |
| 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. |
| <P></P> |
| 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. |
| <P></P> |
| <OL START="3"><LI> 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: |
| <P></P> |
| </OL>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, |
| <P></P> |
| 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, |
| <P></P> |
| 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.) |
| <P></P> |
| 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. |
| <P></P> |
| 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. |
| <P></P> |
| <OL START="4"><LI> 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. |
| <P></P> |
| <LI> 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. |
| <P></P> |
| <LI> 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. |
| <P></P> |
| </OL>You are not responsible for enforcing compliance by third parties to this |
| License. |
| <P></P> |
| <OL START="7"><LI> 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. |
| <P></P> |
| </OL>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. |
| <P></P> |
| 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. |
| <P></P> |
| This section is intended to make thoroughly clear what is believed to be a |
| consequence of the rest of this License. |
| <P></P> |
| <OL START="8"><LI> 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. |
| <P></P> |
| <LI> 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. |
| <P></P> |
| </OL>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. |
| <P></P> |
| <OL START="a"><LI> 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. |
| <P></P> |
| </OL>NO WARRANTY |
| <P></P> |
| <OL START="b"><LI> 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. |
| <P></P> |
| <LI> 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. |
| <P></P> |
| </OL>END OF TERMS AND CONDITIONS |
| <P></P> |
| <B>How to Apply These Terms to Your New Programs |
| <P></P> |
| </B>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. |
| <P></P> |
| 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. |
| <P></P> |
| <I>one line for the program's name and a brief idea of what it does. |
| <BR></I>Copyright (C) 19<I>yy</I> <I>name of author</I> |
| <BR> |
| <BR>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. |
| <BR> |
| <BR>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. |
| <BR> |
| <BR>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. |
| <P></P> |
| Also add information on how to contact you by electronic and paper mail. |
| <P></P> |
| If the program is interactive, make it output a short notice like the |
| following example when it starts in an interactive mode: |
| <P></P> |
| Gnomovision version 69, Copyright (C) 19yy 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. |
| <P></P> |
| The hypothetical commands <B>show w</B> and <B>show c</B> 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 can be mouse clicks or menu itemswhatever suits your program. |
| <P></P> |
| 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. The following is a sample (when copying, alter |
| the names). |
| <P></P> |
| Yoyodyne, Inc., hereby disclaims all copyright interest in the program `Gnomovision' (which makes passes at compilers) written by James Hacker. |
| <BR> |
| <BR>signature of Ty Coon, 1 April 1989 |
| <BR>Ty Coon, President of Vice |
| <P></P> |
| 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. |
