" 59 Temple Place, Suite 330, Boston, MA 02111-1307 USA\n" +
" Everyone is permitted to copy and distribute verbatim copies\n" +
" of this license document, but changing it is not allowed.\n" +
"\n" +
"\t\t\t Preamble\n" +
"\n" +
" The licenses for most software are designed to take away your\n" +
"freedom to share and change it. By contrast, the GNU General Public\n" +
"License is intended to guarantee your freedom to share and change free\n" +
"software--to make sure the software is free for all its users. This\n" +
"General Public License applies to most of the Free Software\n" +
"Foundation's software and to any other program whose authors commit to\n" +
"using it. (Some other Free Software Foundation software is covered by\n" +
"the GNU Library General Public License instead.) You can apply it to\n" +
"your programs, too.\n" +
"\n" +
" When we speak of free software, we are referring to freedom, not\n" +
"price. Our General Public Licenses are designed to make sure that you\n" +
"have the freedom to distribute copies of free software (and charge for\n" +
"this service if you wish), that you receive source code or can get it\n" +
"if you want it, that you can change the software or use pieces of it\n" +
"in new free programs; and that you know you can do these things.\n" +
"\n" +
" To protect your rights, we need to make restrictions that forbid\n" +
"anyone to deny you these rights or to ask you to surrender the rights.\n" +
"These restrictions translate to certain responsibilities for you if you\n" +
"distribute copies of the software, or if you modify it.\n" +
"\n" +
" For example, if you distribute copies of such a program, whether\n" +
"gratis or for a fee, you must give the recipients all the rights that\n" +
"you have. You must make sure that they, too, receive or can get the\n" +
"source code. And you must show them these terms so they know their\n" +
"rights.\n" +
"\n" +
" We protect your rights with two steps: (1) copyright the software, and\n" +
"(2) offer you this license which gives you legal permission to copy,\n" +
"distribute and/or modify the software.\n" +
"\n" +
" Also, for each author's protection and ours, we want to make certain\n" +
"that everyone understands that there is no warranty for this free\n" +
"software. If the software is modified by someone else and passed on, we\n" +
"want its recipients to know that what they have is not the original, so\n" +
"that any problems introduced by others will not reflect on the original\n" +
"authors' reputations.\n" +
"\n" +
" Finally, any free program is threatened constantly by software\n" +
"patents. We wish to avoid the danger that redistributors of a free\n" +
"program will individually obtain patent licenses, in effect making the\n" +
"program proprietary. To prevent this, we have made it clear that any\n" +
"patent must be licensed for everyone's free use or not licensed at all.\n" +
"\n" +
" The precise terms and conditions for copying, distribution and\n" +
"modification follow.\n" +
"\f\n" +
"\t\t GNU GENERAL PUBLIC LICENSE\n" +
" TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION\n" +
"\n" +
" 0. This License applies to any program or other work which contains\n" +
"a notice placed by the copyright holder saying it may be distributed\n" +
"under the terms of this General Public License. The \"Program\", below,\n" +
"refers to any such program or work, and a \"work based on the Program\"\n" +
"means either the Program or any derivative work under copyright law:\n" +
"that is to say, a work containing the Program or a portion of it,\n" +
"either verbatim or with modifications and/or translated into another\n" +
"language. (Hereinafter, translation is included without limitation in\n" +
"the term \"modification\".) Each licensee is addressed as \"you\".\n" +
"\n" +
"Activities other than copying, distribution and modification are not\n" +
"covered by this License; they are outside its scope. The act of\n" +
"running the Program is not restricted, and the output from the Program\n" +
"is covered only if its contents constitute a work based on the\n" +
"Program (independent of having been made by running the Program).\n" +
"Whether that is true depends on what the Program does.\n" +
"\n" +
" 1. You may copy and distribute verbatim copies of the Program's\n" +
"source code as you receive it, in any medium, provided that you\n" +
"conspicuously and appropriately publish on each copy an appropriate\n" +
"copyright notice and disclaimer of warranty; keep intact all the\n" +
"notices that refer to this License and to the absence of any warranty;\n" +
"and give any other recipients of the Program a copy of this License\n" +
"along with the Program.\n" +
"\n" +
"You may charge a fee for the physical act of transferring a copy, and\n" +
"you may at your option offer warranty protection in exchange for a fee.\n" +
"\n" +
" 2. You may modify your copy or copies of the Program or any portion\n" +
"of it, thus forming a work based on the Program, and copy and\n" +
"distribute such modifications or work under the terms of Section 1\n" +
"above, provided that you also meet all of these conditions:\n" +
"\n" +
" a) You must cause the modified files to carry prominent notices\n" +
" stating that you changed the files and the date of any change.\n" +
"\n" +
" b) You must cause any work that you distribute or publish, that in\n" +
" whole or in part contains or is derived from the Program or any\n" +
" part thereof, to be licensed as a whole at no charge to all third\n" +
" parties under the terms of this License.\n" +
"\n" +
" c) If the modified program normally reads commands interactively\n" +
" when run, you must cause it, when started running for such\n" +
" interactive use in the most ordinary way, to print or display an\n" +
" announcement including an appropriate copyright notice and a\n" +
" notice that there is no warranty (or else, saying that you provide\n" +
" a warranty) and that users may redistribute the program under\n" +
" these conditions, and telling the user how to view a copy of this\n" +
" License. (Exception: if the Program itself is interactive but\n" +
" does not normally print such an announcement, your work based on\n" +
" the Program is not required to print an announcement.)\n" +
"\f\n" +
"These requirements apply to the modified work as a whole. If\n" +
"identifiable sections of that work are not derived from the Program,\n" +
"and can be reasonably considered independent and separate works in\n" +
"themselves, then this License, and its terms, do not apply to those\n" +
"sections when you distribute them as separate works. But when you\n" +
"distribute the same sections as part of a whole which is a work based\n" +
"on the Program, the distribution of the whole must be on the terms of\n" +
"this License, whose permissions for other licensees extend to the\n" +
"entire whole, and thus to each and every part regardless of who wrote it.\n" +
"\n" +
"Thus, it is not the intent of this section to claim rights or contest\n" +
"your rights to work written entirely by you; rather, the intent is to\n" +
"exercise the right to control the distribution of derivative or\n" +
"collective works based on the Program.\n" +
"\n" +
"In addition, mere aggregation of another work not based on the Program\n" +
"with the Program (or with a work based on the Program) on a volume of\n" +
"a storage or distribution medium does not bring the other work under\n" +
"the scope of this License.\n" +
"\n" +
" 3. You may copy and distribute the Program (or a work based on it,\n" +
"under Section 2) in object code or executable form under the terms of\n" +
"Sections 1 and 2 above provided that you also do one of the following:\n" +
"\n" +
" a) Accompany it with the complete corresponding machine-readable\n" +
" source code, which must be distributed under the terms of Sections\n" +
" 1 and 2 above on a medium customarily used for software interchange; or,\n" +
"\n" +
" b) Accompany it with a written offer, valid for at least three\n" +
" years, to give any third party, for a charge no more than your\n" +
" cost of physically performing source distribution, a complete\n" +
" machine-readable copy of the corresponding source code, to be\n" +
" distributed under the terms of Sections 1 and 2 above on a medium\n" +
" customarily used for software interchange; or,\n" +
"\n" +
" c) Accompany it with the information you received as to the offer\n" +
" to distribute corresponding source code. (This alternative is\n" +
" allowed only for noncommercial distribution and only if you\n" +
" received the program in object code or executable form with such\n" +
" an offer, in accord with Subsection b above.)\n" +
"\n" +
"The source code for a work means the preferred form of the work for\n" +
"making modifications to it. For an executable work, complete source\n" +
"code means all the source code for all modules it contains, plus any\n" +
"associated interface definition files, plus the scripts used to\n" +
"control compilation and installation of the executable. However, as a\n" +
"special exception, the source code distributed need not include\n" +
"anything that is normally distributed (in either source or binary\n" +
"form) with the major components (compiler, kernel, and so on) of the\n" +
"operating system on which the executable runs, unless that component\n" +
"itself accompanies the executable.\n" +
"\n" +
"If distribution of executable or object code is made by offering\n" +
"access to copy from a designated place, then offering equivalent\n" +
"access to copy the source code from the same place counts as\n" +
"distribution of the source code, even though third parties are not\n" +
"compelled to copy the source along with the object code.\n" +
"\f\n" +
" 4. You may not copy, modify, sublicense, or distribute the Program\n" +
"except as expressly provided under this License. Any attempt\n" +
"otherwise to copy, modify, sublicense or distribute the Program is\n" +
"void, and will automatically terminate your rights under this License.\n" +
"However, parties who have received copies, or rights, from you under\n" +
"this License will not have their licenses terminated so long as such\n" +
"parties remain in full compliance.\n" +
"\n" +
" 5. You are not required to accept this License, since you have not\n" +
"signed it. However, nothing else grants you permission to modify or\n" +
"distribute the Program or its derivative works. These actions are\n" +
"prohibited by law if you do not accept this License. Therefore, by\n" +
"modifying or distributing the Program (or any work based on the\n" +
"Program), you indicate your acceptance of this License to do so, and\n" +
"all its terms and conditions for copying, distributing or modifying\n" +
"the Program or works based on it.\n" +
"\n" +
" 6. Each time you redistribute the Program (or any work based on the\n" +
"Program), the recipient automatically receives a license from the\n" +
"original licensor to copy, distribute or modify the Program subject to\n" +
"these terms and conditions. You may not impose any further\n" +
"restrictions on the recipients' exercise of the rights granted herein.\n" +
"You are not responsible for enforcing compliance by third parties to\n" +
"this License.\n" +
"\n" +
" 7. If, as a consequence of a court judgment or allegation of patent\n" +
"infringement or for any other reason (not limited to patent issues),\n" +
"conditions are imposed on you (whether by court order, agreement or\n" +
"otherwise) that contradict the conditions of this License, they do not\n" +
"excuse you from the conditions of this License. If you cannot\n" +
"distribute so as to satisfy simultaneously your obligations under this\n" +
"License and any other pertinent obligations, then as a consequence you\n" +
"may not distribute the Program at all. For example, if a patent\n" +
"license would not permit royalty-free redistribution of the Program by\n" +
"all those who receive copies directly or indirectly through you, then\n" +
"the only way you could satisfy both it and this License would be to\n" +
"refrain entirely from distribution of the Program.\n" +
"\n" +
"If any portion of this section is held invalid or unenforceable under\n" +
"any particular circumstance, the balance of the section is intended to\n" +
"apply and the section as a whole is intended to apply in other\n" +
"circumstances.\n" +
"\n" +
"It is not the purpose of this section to induce you to infringe any\n" +
"patents or other property right claims or to contest validity of any\n" +
"such claims; this section has the sole purpose of protecting the\n" +
"integrity of the free software distribution system, which is\n" +
"implemented by public license practices. Many people have made\n" +
"generous contributions to the wide range of software distributed\n" +
"through that system in reliance on consistent application of that\n" +
"system; it is up to the author/donor to decide if he or she is willing\n" +
"to distribute software through any other system and a licensee cannot\n" +
"impose that choice.\n" +
"\n" +
"This section is intended to make thoroughly clear what is believed to\n" +
"be a consequence of the rest of this License.\n" +
"\f\n" +
" 8. If the distribution and/or use of the Program is restricted in\n" +
"certain countries either by patents or by copyrighted interfaces, the\n" +
"original copyright holder who places the Program under this License\n" +
"may add an explicit geographical distribution limitation excluding\n" +
"those countries, so that distribution is permitted only in or among\n" +
"countries not thus excluded. In such case, this License incorporates\n" +
"the limitation as if written in the body of this License.\n" +
"\n" +
" 9. The Free Software Foundation may publish revised and/or new versions\n" +
"of the General Public License from time to time. Such new versions will\n" +
"be similar in spirit to the present version, but may differ in detail to\n" +
"address new problems or concerns.\n" +
"\n" +
"Each version is given a distinguishing version number. If the Program\n" +
"specifies a version number of this License which applies to it and \"any\n" +
"later version\", you have the option of following the terms and conditions\n" +
"either of that version or of any later version published by the Free\n" +
"Software Foundation. If the Program does not specify a version number of\n" +
"this License, you may choose any version ever published by the Free Software\n" +
"Foundation.\n" +
"\n" +
" 10. If you wish to incorporate parts of the Program into other free\n" +
"programs whose distribution conditions are different, write to the author\n" +
"to ask for permission. For software which is copyrighted by the Free\n" +
"Software Foundation, write to the Free Software Foundation; we sometimes\n" +
"make exceptions for this. Our decision will be guided by the two goals\n" +
"of preserving the free status of all derivatives of our free software and\n" +
"of promoting the sharing and reuse of software generally.\n" +
"\n" +
"\t\t\t NO WARRANTY\n" +
"\n" +
" 11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY\n" +
"FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW. EXCEPT WHEN\n" +
"OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES\n" +
"PROVIDE THE PROGRAM \"AS IS\" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED\n" +
"OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF\n" +
"MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. THE ENTIRE RISK AS\n" +
"TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU. SHOULD THE\n" +
"PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING,\n" +
"REPAIR OR CORRECTION.\n" +
"\n" +
" 12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING\n" +
"WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR\n" +
"REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES,\n" +
"INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING\n" +
"OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED\n" +
"TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY\n" +
"YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER\n" +
"PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE\n" +
"POSSIBILITY OF SUCH DAMAGES.\n" +
