<pre> GNU GENERAL PUBLIC LICENSE<br/> Version 2, June 1991<br/><br/> Copyright (C) 1989, 1991 Free Software Foundation, Inc.<br/> 59 Temple Place, Suite 330, Boston, MA 02111-1307 USA<br/> Everyone is permitted to copy and distribute verbatim copies<br/> of this license document, but changing it is not allowed.<br/><br/> Preamble<br/><br/> The licenses for most software are designed to take away your<br/>freedom to share and change it. By contrast, the GNU General Public<br/>License is intended to guarantee your freedom to share and change free<br/>software--to make sure the software is free for all its users. This<br/>General Public License applies to most of the Free Software<br/>Foundation's software and to any other program whose authors commit to<br/>using it. (Some other Free Software Foundation software is covered by<br/>the GNU Library General Public License instead.) You can apply it to<br/>your programs, too.<br/><br/> When we speak of free software, we are referring to freedom, not<br/>price. Our General Public Licenses are designed to make sure that you<br/>have the freedom to distribute copies of free software (and charge for<br/>this service if you wish), that you receive source code or can get it<br/>if you want it, that you can change the software or use pieces of it<br/>in new free programs; and that you know you can do these things.<br/><br/> To protect your rights, we need to make restrictions that forbid<br/>anyone to deny you these rights or to ask you to surrender the rights.<br/>These restrictions translate to certain responsibilities for you if you<br/>distribute copies of the software, or if you modify it.<br/><br/> For example, if you distribute copies of such a program, whether<br/>gratis or for a fee, you must give the recipients all the rights that<br/>you have. You must make sure that they, too, receive or can get the<br/>source code. And you must show them these terms so they know their<br/>rights.<br/><br/> We protect your rights with two steps: (1) copyright the software, and<br/>(2) offer you this license which gives you legal permission to copy,<br/>distribute and/or modify the software.<br/><br/> Also, for each author's protection and ours, we want to make certain<br/>that everyone understands that there is no warranty for this free<br/>software. If the software is modified by someone else and passed on, we<br/>want its recipients to know that what they have is not the original, so<br/>that any problems introduced by others will not reflect on the original<br/>authors' reputations.<br/><br/> Finally, any free program is threatened constantly by software<br/>patents. We wish to avoid the danger that redistributors of a free<br/>program will individually obtain patent licenses, in effect making the<br/>program proprietary. To prevent this, we have made it clear that any<br/>patent must be licensed for everyone's free use or not licensed at all.<br/><br/> The precise terms and conditions for copying, distribution and<br/>modification follow.<br/><br/> GNU GENERAL PUBLIC LICENSE<br/> TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION<br/><br/> 0. This License applies to any program or other work which contains<br/>a notice placed by the copyright holder saying it may be distributed<br/>under the terms of this General Public License. The "Program", below,<br/>refers to any such program or work, and a "work based on the Program"<br/>means either the Program or any derivative work under copyright law:<br/>that is to say, a work containing the Program or a portion of it,<br/>either verbatim or with modifications and/or translated into another<br/>language. (Hereinafter, translation is included without limitation in<br/>the term "modification".) Each licensee is addressed as "you".<br/><br/>Activities other than copying, distribution and modification are not<br/>covered by this License; they are outside its scope. The act of<br/>running the Program is not
