| <h2>GNU GENERAL PUBLIC LICENSE</h2> |
| <p> |
| Version 2, June 1991 |
| </p> |
| Copyright (C) 1989, 1991 Free Software Foundation, Inc. <br> |
| 59 Temple Place - Suite 330, Boston, MA 02111-1307, USA<br> |
| <br> |
| Everyone is permitted to copy and distribute verbatim copies<br> |
| of this license document, but changing it is not allowed.<br> |
| <h2>Preamble</h2> |
| <p> 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. |
| </p> |
| <p> The precise terms and conditions for copying, distribution and |
| modification follow. |
| </p> |
| <h2>TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION</h2> |
| <p> |
| <strong>0.</strong> 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><strong>1.</strong> 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>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><strong>2.</strong> 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> |
| <ul> |
| <li><strong>a)</strong> You must cause the modified files to carry |
| prominent notices stating that you changed the files and the date of |
| any change. </li> |
| <li><strong>b)</strong> 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. </li> |
| <li><strong>c)</strong> 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.) </li> |
| </ul> |
| 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>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><strong>3.</strong> 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: |
| <!-- we use this doubled UL to get the sub-sections indented, --><!-- while making the bullets as unobvious as possible. --></p> |
| <ul> |
| <li><strong>a)</strong> 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, </li> |
| <li><strong>b)</strong> 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, </li> |
| <li><strong>c)</strong> 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.) </li> |
| </ul> |
| 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>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><strong>4.</strong> 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><strong>5.</strong> 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><strong>6.</strong> 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. |
| </p> |
| <p><strong>7.</strong> 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>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><strong>8.</strong> 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><strong>9.</strong> 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>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><strong>10.</strong> 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><strong>NO WARRANTY</strong></p> |
| <p> |
| <strong>11.</strong> 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><strong>12.</strong> 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> |
| <h2>END OF TERMS AND CONDITIONS</h2> |
| <h2>How to Apply These Terms to Your New Programs</h2> |
| <p> 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> |
| <var>one line to give the program's name and an idea of what it does.</var><br> |
| Copyright (C) <var>yyyy</var> <var>name of author</var><br> |
| <br> |
| This program is free software; you can redistribute it and/or<br> |
| modify it under the terms of the GNU General Public License<br> |
| as published by the Free Software Foundation; either version 2<br> |
| of the License, or (at your option) any later version.<br> |
| <br> |
| This program is distributed in the hope that it will be useful,<br> |
| but WITHOUT ANY WARRANTY; without even the implied warranty of<br> |
| MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the<br> |
| GNU General Public License for more details.<br> |
| <br> |
| You should have received a copy of the GNU General Public License<br> |
| along with this program; if not, write to the Free Software<br> |
| Foundation, Inc., 59 Temple Place - Suite 330, Boston, MA 02111-1307, |
| USA.<br> |
| <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 this |
| when it starts in an interactive mode: |
| </p> |
| Gnomovision version 69, Copyright (C) <var>year</var> <var>name of author</var><br>Gnomovision comes with ABSOLUTELY NO WARRANTY; for details<br>type `show w'. This is free software, and you are welcome<br>to redistribute it under certain conditions; type `show c' <br>for details.<br></pre> |
| <p> |
| The hypothetical commands <samp>`show w'</samp> and <samp>`show c'</samp> |
| should show |
| the appropriate parts of the General Public License. Of course, the |
| commands you use may be called something other than <samp>`show w'</samp> |
| and |
| <samp>`show c'</samp>; they could even be mouse-clicks or menu |
| items--whatever |
| 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. Here is a sample; alter the names: |
| </p> |
| Yoyodyne, Inc., hereby disclaims all copyright<br> |
| interest in the program `Gnomovision'<br> |
| (which makes passes at compilers) written <br> |
| by James Hacker.<br> |
| <br> |
| <var>signature of Ty Coon</var>, 1 April 1989<br> |
| Ty Coon, President of Vice<br> |
| <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 Lesser General |
| Public License instead of this License. |
