- Version 2, June 1991\r
-\r
- Copyright (C) 1989, 1991 Free Software Foundation, Inc.\r
- 675 Mass Ave, Cambridge, MA 02139, USA\r
- Everyone is permitted to copy and distribute verbatim copies\r
- of this license document, but changing it is not allowed.\r
-\r
- Preamble\r
-\r
- The licenses for most software are designed to take away your\r
-freedom to share and change it. By contrast, the GNU General Public\r
-License is intended to guarantee your freedom to share and change free\r
-software--to make sure the software is free for all its users. This\r
-General Public License applies to most of the Free Software\r
-Foundation's software and to any other program whose authors commit to\r
-using it. (Some other Free Software Foundation software is covered by\r
-the GNU Library General Public License instead.) You can apply it to\r
-your programs, too.\r
-\r
- When we speak of free software, we are referring to freedom, not\r
-price. Our General Public Licenses are designed to make sure that you\r
-have the freedom to distribute copies of free software (and charge for\r
-this service if you wish), that you receive source code or can get it\r
-if you want it, that you can change the software or use pieces of it\r
-in new free programs; and that you know you can do these things.\r
-\r
- To protect your rights, we need to make restrictions that forbid\r
-anyone to deny you these rights or to ask you to surrender the rights.\r
-These restrictions translate to certain responsibilities for you if you\r
-distribute copies of the software, or if you modify it.\r
-\r
- For example, if you distribute copies of such a program, whether\r
-gratis or for a fee, you must give the recipients all the rights that\r
-you have. You must make sure that they, too, receive or can get the\r
-source code. And you must show them these terms so they know their\r
-rights.\r
-\r
- We protect your rights with two steps: (1) copyright the software, and\r
-(2) offer you this license which gives you legal permission to copy,\r
-distribute and/or modify the software.\r
-\r
- Also, for each author's protection and ours, we want to make certain\r
-that everyone understands that there is no warranty for this free\r
-software. If the software is modified by someone else and passed on, we\r
-want its recipients to know that what they have is not the original, so\r
-that any problems introduced by others will not reflect on the original\r
-authors' reputations.\r
-\r
- Finally, any free program is threatened constantly by software\r
-patents. We wish to avoid the danger that redistributors of a free\r
-program will individually obtain patent licenses, in effect making the\r
-program proprietary. To prevent this, we have made it clear that any\r
-patent must be licensed for everyone's free use or not licensed at all.\r
-\r
- The precise terms and conditions for copying, distribution and\r
-modification follow.\r
-\f\r
- GNU GENERAL PUBLIC LICENSE\r
- TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION\r
-\r
- 0. This License applies to any program or other work which contains\r
-a notice placed by the copyright holder saying it may be distributed\r
-under the terms of this General Public License. The "Program", below,\r
-refers to any such program or work, and a "work based on the Program"\r
-means either the Program or any derivative work under copyright law:\r
-that is to say, a work containing the Program or a portion of it,\r
-either verbatim or with modifications and/or translated into another\r
-language. (Hereinafter, translation is included without limitation in\r
-the term "modification".) Each licensee is addressed as "you".\r
-\r
-Activities other than copying, distribution and modification are not\r
-covered by this License; they are outside its scope. The act of\r
-running the Program is not restricted, and the output from the Program\r
-is covered only if its contents constitute a work based on the\r
-Program (independent of having been made by running the Program).\r
-Whether that is true depends on what the Program does.\r
-\r
- 1. You may copy and distribute verbatim copies of the Program's\r
-source code as you receive it, in any medium, provided that you\r
-conspicuously and appropriately publish on each copy an appropriate\r
-copyright notice and disclaimer of warranty; keep intact all the\r
-notices that refer to this License and to the absence of any warranty;\r
-and give any other recipients of the Program a copy of this License\r
-along with the Program.\r
-\r
-You may charge a fee for the physical act of transferring a copy, and\r
-you may at your option offer warranty protection in exchange for a fee.\r
-\r
- 2. You may modify your copy or copies of the Program or any portion\r
-of it, thus forming a work based on the Program, and copy and\r
-distribute such modifications or work under the terms of Section 1\r
-above, provided that you also meet all of these conditions:\r
-\r
- a) You must cause the modified files to carry prominent notices\r
- stating that you changed the files and the date of any change.\r
-\r
- b) You must cause any work that you distribute or publish, that in\r
- whole or in part contains or is derived from the Program or any\r
- part thereof, to be licensed as a whole at no charge to all third\r
- parties under the terms of this License.\r
-\r
- c) If the modified program normally reads commands interactively\r
- when run, you must cause it, when started running for such\r
- interactive use in the most ordinary way, to print or display an\r
- announcement including an appropriate copyright notice and a\r
- notice that there is no warranty (or else, saying that you provide\r
- a warranty) and that users may redistribute the program under\r
- these conditions, and telling the user how to view a copy of this\r
- License. (Exception: if the Program itself is interactive but\r
- does not normally print such an announcement, your work based on\r
- the Program is not required to print an announcement.)\r
-\f\r
-These requirements apply to the modified work as a whole. If\r
-identifiable sections of that work are not derived from the Program,\r
-and can be reasonably considered independent and separate works in\r
-themselves, then this License, and its terms, do not apply to those\r
-sections when you distribute them as separate works. But when you\r
-distribute the same sections as part of a whole which is a work based\r
-on the Program, the distribution of the whole must be on the terms of\r
-this License, whose permissions for other licensees extend to the\r
-entire whole, and thus to each and every part regardless of who wrote it.\r
-\r
-Thus, it is not the intent of this section to claim rights or contest\r
-your rights to work written entirely by you; rather, the intent is to\r
-exercise the right to control the distribution of derivative or\r
-collective works based on the Program.\r
-\r
-In addition, mere aggregation of another work not based on the Program\r
-with the Program (or with a work based on the Program) on a volume of\r
-a storage or distribution medium does not bring the other work under\r
-the scope of this License.\r
-\r
- 3. You may copy and distribute the Program (or a work based on it,\r
-under Section 2) in object code or executable form under the terms of\r
-Sections 1 and 2 above provided that you also do one of the following:\r
-\r
- a) Accompany it with the complete corresponding machine-readable\r
- source code, which must be distributed under the terms of Sections\r
- 1 and 2 above on a medium customarily used for software interchange; or,\r
-\r
- b) Accompany it with a written offer, valid for at least three\r
- years, to give any third party, for a charge no more than your\r
- cost of physically performing source distribution, a complete\r
- machine-readable copy of the corresponding source code, to be\r
- distributed under the terms of Sections 1 and 2 above on a medium\r
- customarily used for software interchange; or,\r
-\r
- c) Accompany it with the information you received as to the offer\r
- to distribute corresponding source code. (This alternative is\r
- allowed only for noncommercial distribution and only if you\r
- received the program in object code or executable form with such\r
- an offer, in accord with Subsection b above.)\r
-\r
-The source code for a work means the preferred form of the work for\r
-making modifications to it. For an executable work, complete source\r
-code means all the source code for all modules it contains, plus any\r
-associated interface definition files, plus the scripts used to\r
-control compilation and installation of the executable. However, as a\r
-special exception, the source code distributed need not include\r
-anything that is normally distributed (in either source or binary\r
-form) with the major components (compiler, kernel, and so on) of the\r
-operating system on which the executable runs, unless that component\r
-itself accompanies the executable.\r
-\r
-If distribution of executable or object code is made by offering\r
-access to copy from a designated place, then offering equivalent\r
-access to copy the source code from the same place counts as\r
-distribution of the source code, even though third parties are not\r
-compelled to copy the source along with the object code.\r
-\f\r
- 4. You may not copy, modify, sublicense, or distribute the Program\r
-except as expressly provided under this License. Any attempt\r
-otherwise to copy, modify, sublicense or distribute the Program is\r
-void, and will automatically terminate your rights under this License.\r
-However, parties who have received copies, or rights, from you under\r
-this License will not have their licenses terminated so long as such\r
-parties remain in full compliance.\r
-\r
- 5. You are not required to accept this License, since you have not\r
-signed it. However, nothing else grants you permission to modify or\r
-distribute the Program or its derivative works. These actions are\r
-prohibited by law if you do not accept this License. Therefore, by\r
-modifying or distributing the Program (or any work based on the\r
-Program), you indicate your acceptance of this License to do so, and\r
-all its terms and conditions for copying, distributing or modifying\r
-the Program or works based on it.\r
-\r
- 6. Each time you redistribute the Program (or any work based on the\r
-Program), the recipient automatically receives a license from the\r
-original licensor to copy, distribute or modify the Program subject to\r
-these terms and conditions. You may not impose any further\r
-restrictions on the recipients' exercise of the rights granted herein.\r
-You are not responsible for enforcing compliance by third parties to\r
-this License.\r
-\r
- 7. If, as a consequence of a court judgment or allegation of patent\r
-infringement or for any other reason (not limited to patent issues),\r
-conditions are imposed on you (whether by court order, agreement or\r
-otherwise) that contradict the conditions of this License, they do not\r
-excuse you from the conditions of this License. If you cannot\r
-distribute so as to satisfy simultaneously your obligations under this\r
-License and any other pertinent obligations, then as a consequence you\r
-may not distribute the Program at all. For example, if a patent\r
-license would not permit royalty-free redistribution of the Program by\r
-all those who receive copies directly or indirectly through you, then\r
-the only way you could satisfy both it and this License would be to\r
-refrain entirely from distribution of the Program.\r
-\r
-If any portion of this section is held invalid or unenforceable under\r
-any particular circumstance, the balance of the section is intended to\r
-apply and the section as a whole is intended to apply in other\r
-circumstances.\r
-\r
-It is not the purpose of this section to induce you to infringe any\r
-patents or other property right claims or to contest validity of any\r
-such claims; this section has the sole purpose of protecting the\r
-integrity of the free software distribution system, which is\r
-implemented by public license practices. Many people have made\r
-generous contributions to the wide range of software distributed\r
-through that system in reliance on consistent application of that\r
-system; it is up to the author/donor to decide if he or she is willing\r
-to distribute software through any other system and a licensee cannot\r
-impose that choice.\r
-\r
-This section is intended to make thoroughly clear what is believed to\r
-be a consequence of the rest of this License.\r
-\f\r
- 8. If the distribution and/or use of the Program is restricted in\r
-certain countries either by patents or by copyrighted interfaces, the\r
-original copyright holder who places the Program under this License\r
-may add an explicit geographical distribution limitation excluding\r
-those countries, so that distribution is permitted only in or among\r
-countries not thus excluded. In such case, this License incorporates\r
-the limitation as if written in the body of this License.\r
-\r
- 9. The Free Software Foundation may publish revised and/or new versions\r
-of the General Public License from time to time. Such new versions will\r
-be similar in spirit to the present version, but may differ in detail to\r
-address new problems or concerns.\r
-\r
-Each version is given a distinguishing version number. If the Program\r
-specifies a version number of this License which applies to it and "any\r
-later version", you have the option of following the terms and conditions\r
-either of that version or of any later version published by the Free\r
-Software Foundation. If the Program does not specify a version number of\r
-this License, you may choose any version ever published by the Free Software\r
-Foundation.\r
-\r
- 10. If you wish to incorporate parts of the Program into other free\r
-programs whose distribution conditions are different, write to the author\r
-to ask for permission. For software which is copyrighted by the Free\r
-Software Foundation, write to the Free Software Foundation; we sometimes\r
-make exceptions for this. Our decision will be guided by the two goals\r
-of preserving the free status of all derivatives of our free software and\r
-of promoting the sharing and reuse of software generally.\r
-\r
- NO WARRANTY\r
-\r
- 11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY\r
-FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW. EXCEPT WHEN\r
-OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES\r
-PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED\r
-OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF\r
-MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. THE ENTIRE RISK AS\r
-TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU. SHOULD THE\r
-PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING,\r
-REPAIR OR CORRECTION.\r
-\r
- 12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING\r
-WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR\r
-REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES,\r
-INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING\r
-OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED\r
-TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY\r
-YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER\r
-PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE\r
-POSSIBILITY OF SUCH DAMAGES.\r
-\r
- END OF TERMS AND CONDITIONS\r
-\f\r
- Appendix: How to Apply These Terms to Your New Programs\r
-\r
- If you develop a new program, and you want it to be of the greatest\r
-possible use to the public, the best way to achieve this is to make it\r
-free software which everyone can redistribute and change under these terms.\r
-\r
- To do so, attach the following notices to the program. It is safest\r
-to attach them to the start of each source file to most effectively\r
-convey the exclusion of warranty; and each file should have at least\r
-the "copyright" line and a pointer to where the full notice is found.\r
-\r
- <one line to give the program's name and a brief idea of what it does.>\r
- Copyright (C) 19yy <name of author>\r
-\r
- This program is free software; you can redistribute it and/or modify\r
- it under the terms of the GNU General Public License as published by\r
- the Free Software Foundation; either version 2 of the License, or\r
- (at your option) any later version.\r
-\r
- This program is distributed in the hope that it will be useful,\r
- but WITHOUT ANY WARRANTY; without even the implied warranty of\r
- MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the\r
- GNU General Public License for more details.\r
-\r
- You should have received a copy of the GNU General Public License\r
- along with this program; if not, write to the Free Software\r
- Foundation, Inc., 675 Mass Ave, Cambridge, MA 02139, USA.\r
-\r
-Also add information on how to contact you by electronic and paper mail.\r
-\r
-If the program is interactive, make it output a short notice like this\r
-when it starts in an interactive mode:\r
-\r
- Gnomovision version 69, Copyright (C) 19yy name of author\r
- Gnomovision comes with ABSOLUTELY NO WARRANTY; for details type `show w'.\r
- This is free software, and you are welcome to redistribute it\r
- under certain conditions; type `show c' for details.\r
-\r
-The hypothetical commands `show w' and `show c' should show the appropriate\r
-parts of the General Public License. Of course, the commands you use may\r
-be called something other than `show w' and `show c'; they could even be\r
-mouse-clicks or menu items--whatever suits your program.\r
-\r
-You should also get your employer (if you work as a programmer) or your\r
-school, if any, to sign a "copyright disclaimer" for the program, if\r
-necessary. Here is a sample; alter the names:\r
-\r
- Yoyodyne, Inc., hereby disclaims all copyright interest in the program\r
- `Gnomovision' (which makes passes at compilers) written by James Hacker.\r
-\r
- <signature of Ty Coon>, 1 April 1989\r
- Ty Coon, President of Vice\r
-\r
-This General Public License does not permit incorporating your program into\r
-proprietary programs. If your program is a subroutine library, you may\r
-consider it more useful to permit linking proprietary applications with the\r
-library. If this is what you want to do, use the GNU Library General\r
-Public License instead of this License.\r

+ GNU GENERAL PUBLIC LICENSE\r
+ Version 2, June 1991\r
+\r
+ Copyright (C) 1989, 1991 Free Software Foundation, Inc.\r
+ 675 Mass Ave, Cambridge, MA 02139, USA\r
+ Everyone is permitted to copy and distribute verbatim copies\r
+ of this license document, but changing it is not allowed.\r
+\r
+ Preamble\r
+\r
+ The licenses for most software are designed to take away your\r
+freedom to share and change it. By contrast, the GNU General Public\r
+License is intended to guarantee your freedom to share and change free\r
+software--to make sure the software is free for all its users. This\r
+General Public License applies to most of the Free Software\r
+Foundation's software and to any other program whose authors commit to\r
+using it. (Some other Free Software Foundation software is covered by\r
+the GNU Library General Public License instead.) You can apply it to\r
+your programs, too.\r
+\r
+ When we speak of free software, we are referring to freedom, not\r
+price. Our General Public Licenses are designed to make sure that you\r
+have the freedom to distribute copies of free software (and charge for\r
+this service if you wish), that you receive source code or can get it\r
+if you want it, that you can change the software or use pieces of it\r
+in new free programs; and that you know you can do these things.\r
+\r
+ To protect your rights, we need to make restrictions that forbid\r
+anyone to deny you these rights or to ask you to surrender the rights.\r
+These restrictions translate to certain responsibilities for you if you\r
+distribute copies of the software, or if you modify it.\r
+\r
+ For example, if you distribute copies of such a program, whether\r
+gratis or for a fee, you must give the recipients all the rights that\r
+you have. You must make sure that they, too, receive or can get the\r
+source code. And you must show them these terms so they know their\r
+rights.\r
+\r
+ We protect your rights with two steps: (1) copyright the software, and\r
+(2) offer you this license which gives you legal permission to copy,\r
+distribute and/or modify the software.\r
+\r
+ Also, for each author's protection and ours, we want to make certain\r
+that everyone understands that there is no warranty for this free\r
+software. If the software is modified by someone else and passed on, we\r
+want its recipients to know that what they have is not the original, so\r
+that any problems introduced by others will not reflect on the original\r
+authors' reputations.\r
+\r
+ Finally, any free program is threatened constantly by software\r
+patents. We wish to avoid the danger that redistributors of a free\r
+program will individually obtain patent licenses, in effect making the\r
+program proprietary. To prevent this, we have made it clear that any\r
+patent must be licensed for everyone's free use or not licensed at all.\r
+\r
+ The precise terms and conditions for copying, distribution and\r
+modification follow.\r
+\f\r
+ GNU GENERAL PUBLIC LICENSE\r
+ TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION\r
+\r
+ 0. This License applies to any program or other work which contains\r
+a notice placed by the copyright holder saying it may be distributed\r
+under the terms of this General Public License. The "Program", below,\r
+refers to any such program or work, and a "work based on the Program"\r
+means either the Program or any derivative work under copyright law:\r
+that is to say, a work containing the Program or a portion of it,\r
+either verbatim or with modifications and/or translated into another\r
+language. (Hereinafter, translation is included without limitation in\r
+the term "modification".) Each licensee is addressed as "you".\r
+\r
+Activities other than copying, distribution and modification are not\r
+covered by this License; they are outside its scope. The act of\r
+running the Program is not restricted, and the output from the Program\r
+is covered only if its contents constitute a work based on the\r
+Program (independent of having been made by running the Program).\r
+Whether that is true depends on what the Program does.\r
+\r
+ 1. You may copy and distribute verbatim copies of the Program's\r
+source code as you receive it, in any medium, provided that you\r
+conspicuously and appropriately publish on each copy an appropriate\r
+copyright notice and disclaimer of warranty; keep intact all the\r
+notices that refer to this License and to the absence of any warranty;\r
+and give any other recipients of the Program a copy of this License\r
+along with the Program.\r
+\r
+You may charge a fee for the physical act of transferring a copy, and\r
+you may at your option offer warranty protection in exchange for a fee.\r
+\r
+ 2. You may modify your copy or copies of the Program or any portion\r
+of it, thus forming a work based on the Program, and copy and\r
+distribute such modifications or work under the terms of Section 1\r
+above, provided that you also meet all of these conditions:\r
+\r
+ a) You must cause the modified files to carry prominent notices\r
+ stating that you changed the files and the date of any change.\r
+\r
+ b) You must cause any work that you distribute or publish, that in\r
+ whole or in part contains or is derived from the Program or any\r
+ part thereof, to be licensed as a whole at no charge to all third\r
+ parties under the terms of this License.\r
+\r
+ c) If the modified program normally reads commands interactively\r
+ when run, you must cause it, when started running for such\r
+ interactive use in the most ordinary way, to print or display an\r
+ announcement including an appropriate copyright notice and a\r
+ notice that there is no warranty (or else, saying that you provide\r
+ a warranty) and that users may redistribute the program under\r
+ these conditions, and telling the user how to view a copy of this\r
+ License. (Exception: if the Program itself is interactive but\r
+ does not normally print such an announcement, your work based on\r
+ the Program is not required to print an announcement.)\r
+\f\r
+These requirements apply to the modified work as a whole. If\r
+identifiable sections of that work are not derived from the Program,\r
+and can be reasonably considered independent and separate works in\r
+themselves, then this License, and its terms, do not apply to those\r
+sections when you distribute them as separate works. But when you\r
+distribute the same sections as part of a whole which is a work based\r
+on the Program, the distribution of the whole must be on the terms of\r
+this License, whose permissions for other licensees extend to the\r
+entire whole, and thus to each and every part regardless of who wrote it.\r
+\r
+Thus, it is not the intent of this section to claim rights or contest\r
+your rights to work written entirely by you; rather, the intent is to\r
+exercise the right to control the distribution of derivative or\r
+collective works based on the Program.\r
+\r
+In addition, mere aggregation of another work not based on the Program\r
+with the Program (or with a work based on the Program) on a volume of\r
+a storage or distribution medium does not bring the other work under\r
+the scope of this License.\r
+\r
+ 3. You may copy and distribute the Program (or a work based on it,\r
+under Section 2) in object code or executable form under the terms of\r
+Sections 1 and 2 above provided that you also do one of the following:\r
+\r
+ a) Accompany it with the complete corresponding machine-readable\r
+ source code, which must be distributed under the terms of Sections\r
+ 1 and 2 above on a medium customarily used for software interchange; or,\r
+\r
+ b) Accompany it with a written offer, valid for at least three\r
+ years, to give any third party, for a charge no more than your\r
+ cost of physically performing source distribution, a complete\r
+ machine-readable copy of the corresponding source code, to be\r
+ distributed under the terms of Sections 1 and 2 above on a medium\r
+ customarily used for software interchange; or,\r
+\r
+ c) Accompany it with the information you received as to the offer\r
+ to distribute corresponding source code. (This alternative is\r
+ allowed only for noncommercial distribution and only if you\r
+ received the program in object code or executable form with such\r
+ an offer, in accord with Subsection b above.)\r
+\r
+The source code for a work means the preferred form of the work for\r
+making modifications to it. For an executable work, complete source\r
+code means all the source code for all modules it contains, plus any\r
+associated interface definition files, plus the scripts used to\r
+control compilation and installation of the executable. However, as a\r
+special exception, the source code distributed need not include\r
+anything that is normally distributed (in either source or binary\r
+form) with the major components (compiler, kernel, and so on) of the\r
+operating system on which the executable runs, unless that component\r
+itself accompanies the executable.\r
+\r
+If distribution of executable or object code is made by offering\r
+access to copy from a designated place, then offering equivalent\r
+access to copy the source code from the same place counts as\r
+distribution of the source code, even though third parties are not\r
+compelled to copy the source along with the object code.\r
+\f\r
+ 4. You may not copy, modify, sublicense, or distribute the Program\r
+except as expressly provided under this License. Any attempt\r
+otherwise to copy, modify, sublicense or distribute the Program is\r
+void, and will automatically terminate your rights under this License.\r
+However, parties who have received copies, or rights, from you under\r
+this License will not have their licenses terminated so long as such\r
+parties remain in full compliance.\r
+\r
+ 5. You are not required to accept this License, since you have not\r
+signed it. However, nothing else grants you permission to modify or\r
+distribute the Program or its derivative works. These actions are\r
+prohibited by law if you do not accept this License. Therefore, by\r
+modifying or distributing the Program (or any work based on the\r
+Program), you indicate your acceptance of this License to do so, and\r
+all its terms and conditions for copying, distributing or modifying\r
+the Program or works based on it.\r
+\r
+ 6. Each time you redistribute the Program (or any work based on the\r
+Program), the recipient automatically receives a license from the\r
+original licensor to copy, distribute or modify the Program subject to\r
+these terms and conditions. You may not impose any further\r
+restrictions on the recipients' exercise of the rights granted herein.\r
+You are not responsible for enforcing compliance by third parties to\r
+this License.\r
+\r
+ 7. If, as a consequence of a court judgment or allegation of patent\r
+infringement or for any other reason (not limited to patent issues),\r
+conditions are imposed on you (whether by court order, agreement or\r
+otherwise) that contradict the conditions of this License, they do not\r
+excuse you from the conditions of this License. If you cannot\r
+distribute so as to satisfy simultaneously your obligations under this\r
+License and any other pertinent obligations, then as a consequence you\r
+may not distribute the Program at all. For example, if a patent\r
+license would not permit royalty-free redistribution of the Program by\r
+all those who receive copies directly or indirectly through you, then\r
+the only way you could satisfy both it and this License would be to\r
+refrain entirely from distribution of the Program.\r
+\r
+If any portion of this section is held invalid or unenforceable under\r
+any particular circumstance, the balance of the section is intended to\r
+apply and the section as a whole is intended to apply in other\r
+circumstances.\r
+\r
+It is not the purpose of this section to induce you to infringe any\r
+patents or other property right claims or to contest validity of any\r
+such claims; this section has the sole purpose of protecting the\r
+integrity of the free software distribution system, which is\r
+implemented by public license practices. Many people have made\r
+generous contributions to the wide range of software distributed\r
+through that system in reliance on consistent application of that\r
+system; it is up to the author/donor to decide if he or she is willing\r
+to distribute software through any other system and a licensee cannot\r
+impose that choice.\r
+\r
+This section is intended to make thoroughly clear what is believed to\r
+be a consequence of the rest of this License.\r
+\f\r
+ 8. If the distribution and/or use of the Program is restricted in\r
+certain countries either by patents or by copyrighted interfaces, the\r
+original copyright holder who places the Program under this License\r
+may add an explicit geographical distribution limitation excluding\r
+those countries, so that distribution is permitted only in or among\r
+countries not thus excluded. In such case, this License incorporates\r
+the limitation as if written in the body of this License.\r
+\r
+ 9. The Free Software Foundation may publish revised and/or new versions\r
+of the General Public License from time to time. Such new versions will\r
+be similar in spirit to the present version, but may differ in detail to\r
+address new problems or concerns.\r
+\r
+Each version is given a distinguishing version number. If the Program\r
+specifies a version number of this License which applies to it and "any\r
+later version", you have the option of following the terms and conditions\r
+either of that version or of any later version published by the Free\r
+Software Foundation. If the Program does not specify a version number of\r
+this License, you may choose any version ever published by the Free Software\r
+Foundation.\r
+\r
+ 10. If you wish to incorporate parts of the Program into other free\r
+programs whose distribution conditions are different, write to the author\r
+to ask for permission. For software which is copyrighted by the Free\r
+Software Foundation, write to the Free Software Foundation; we sometimes\r
+make exceptions for this. Our decision will be guided by the two goals\r
+of preserving the free status of all derivatives of our free software and\r
+of promoting the sharing and reuse of software generally.\r
+\r
+ NO WARRANTY\r
+\r
+ 11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY\r
+FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW. EXCEPT WHEN\r
+OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES\r
+PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED\r
+OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF\r
+MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. THE ENTIRE RISK AS\r
+TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU. SHOULD THE\r
+PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING,\r
+REPAIR OR CORRECTION.\r
+\r
+ 12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING\r
+WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR\r
+REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES,\r
+INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING\r
+OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED\r
+TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY\r
+YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER\r
+PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE\r
+POSSIBILITY OF SUCH DAMAGES.\r
+\r
+ END OF TERMS AND CONDITIONS\r
+\f\r
+ Appendix: How to Apply These Terms to Your New Programs\r
+\r
+ If you develop a new program, and you want it to be of the greatest\r
+possible use to the public, the best way to achieve this is to make it\r
+free software which everyone can redistribute and change under these terms.\r
+\r
+ To do so, attach the following notices to the program. It is safest\r
+to attach them to the start of each source file to most effectively\r
+convey the exclusion of warranty; and each file should have at least\r
+the "copyright" line and a pointer to where the full notice is found.\r
+\r
+ <one line to give the program's name and a brief idea of what it does.>\r
+ Copyright (C) 19yy <name of author>\r
+\r
+ This program is free software; you can redistribute it and/or modify\r
+ it under the terms of the GNU General Public License as published by\r
+ the Free Software Foundation; either version 2 of the License, or\r

+\r
+ This program is distributed in the hope that it will be useful,\r
+ but WITHOUT ANY WARRANTY; without even the implied warranty of\r
+ MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the\r

+\r
+ You should have received a copy of the GNU General Public License\r
+ along with this program; if not, write to the Free Software\r
+ Foundation, Inc., 675 Mass Ave, Cambridge, MA 02139, USA.\r
+\r
+Also add information on how to contact you by electronic and paper mail.\r
+\r
+If the program is interactive, make it output a short notice like this\r
+when it starts in an interactive mode:\r
+\r
+ Gnomovision version 69, Copyright (C) 19yy name of author\r
+ Gnomovision comes with ABSOLUTELY NO WARRANTY; for details type `show w'.\r
+ This is free software, and you are welcome to redistribute it\r
+ under certain conditions; type `show c' for details.\r
+\r
+The hypothetical commands `show w' and `show c' should show the appropriate\r
+parts of the General Public License. Of course, the commands you use may\r
+be called something other than `show w' and `show c'; they could even be\r
+mouse-clicks or menu items--whatever suits your program.\r
+\r
+You should also get your employer (if you work as a programmer) or your\r
+school, if any, to sign a "copyright disclaimer" for the program, if\r
+necessary. Here is a sample; alter the names:\r
+\r
+ Yoyodyne, Inc., hereby disclaims all copyright interest in the program\r

+This General Public License does not permit incorporating your program into\r

+consider it more useful to permit linking proprietary applications with the\r
+library. If this is what you want to do, use the GNU Library General\r
+Public License instead of this License.\r

+ GNU GENERAL PUBLIC LICENSE
+ Version 3, 29 June 2007
+
+ Copyright (C) 2007 Free Software Foundation, Inc. <http://fsf.org/>
+ Everyone is permitted to copy and distribute verbatim copies
+ of this license document, but changing it is not allowed.
+
+ Preamble
+
+ The GNU General Public License is a free, copyleft license for
+software and other kinds of works.
+
+ The licenses for most software and other practical works are designed
+to take away your freedom to share and change the works. By contrast,
+the GNU General Public License is intended to guarantee your freedom to
+share and change all versions of a program--to make sure it remains free
+software for all its users. We, the Free Software Foundation, use the
+GNU General Public License for most of our software; it applies also to
+any other work released this way by its authors. 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
+them 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 prevent others from denying you
+these rights or asking you to surrender the rights. Therefore, you have
+certain responsibilities if you distribute copies of the software, or if
+you modify it: responsibilities to respect the freedom of others.
+
+ For example, if you distribute copies of such a program, whether
+gratis or for a fee, you must pass on to the recipients the same
+freedoms that you received. 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.
+
+ Developers that use the GNU GPL protect your rights with two steps:
+(1) assert copyright on the software, and (2) offer you this License
+giving you legal permission to copy, distribute and/or modify it.
+
+ For the developers' and authors' protection, the GPL clearly explains
+that there is no warranty for this free software. For both users' and
+authors' sake, the GPL requires that modified versions be marked as
+changed, so that their problems will not be attributed erroneously to
+authors of previous versions.
+
+ Some devices are designed to deny users access to install or run
+modified versions of the software inside them, although the manufacturer
+can do so. This is fundamentally incompatible with the aim of
+protecting users' freedom to change the software. The systematic
+pattern of such abuse occurs in the area of products for individuals to
+use, which is precisely where it is most unacceptable. Therefore, we
+have designed this version of the GPL to prohibit the practice for those
+products. If such problems arise substantially in other domains, we
+stand ready to extend this provision to those domains in future versions
+of the GPL, as needed to protect the freedom of users.
+
+ Finally, every program is threatened constantly by software patents.
+States should not allow patents to restrict development and use of
+software on general-purpose computers, but in those that do, we wish to
+avoid the special danger that patents applied to a free program could
+make it effectively proprietary. To prevent this, the GPL assures that
+patents cannot be used to render the program non-free.
+
+ The precise terms and conditions for copying, distribution and
+modification follow.
+
+ TERMS AND CONDITIONS
+
+ 0. Definitions.
+
+ "This License" refers to version 3 of the GNU General Public License.
+
+ "Copyright" also means copyright-like laws that apply to other kinds of
+works, such as semiconductor masks.
+
+ "The Program" refers to any copyrightable work licensed under this
+License. Each licensee is addressed as "you". "Licensees" and
+"recipients" may be individuals or organizations.
+
+ To "modify" a work means to copy from or adapt all or part of the work
+in a fashion requiring copyright permission, other than the making of an
+exact copy. The resulting work is called a "modified version" of the
+earlier work or a work "based on" the earlier work.
+
+ A "covered work" means either the unmodified Program or a work based
+on the Program.
+
+ To "propagate" a work means to do anything with it that, without
+permission, would make you directly or secondarily liable for
+infringement under applicable copyright law, except executing it on a
+computer or modifying a private copy. Propagation includes copying,
+distribution (with or without modification), making available to the
+public, and in some countries other activities as well.
+
+ To "convey" a work means any kind of propagation that enables other
+parties to make or receive copies. Mere interaction with a user through
+a computer network, with no transfer of a copy, is not conveying.
+
+ An interactive user interface displays "Appropriate Legal Notices"
+to the extent that it includes a convenient and prominently visible
+feature that (1) displays an appropriate copyright notice, and (2)
+tells the user that there is no warranty for the work (except to the
+extent that warranties are provided), that licensees may convey the
+work under this License, and how to view a copy of this License. If
+the interface presents a list of user commands or options, such as a
+menu, a prominent item in the list meets this criterion.
+
+ 1. Source Code.
+
+ The "source code" for a work means the preferred form of the work
+for making modifications to it. "Object code" means any non-source
+form of a work.
+
+ A "Standard Interface" means an interface that either is an official
+standard defined by a recognized standards body, or, in the case of
+interfaces specified for a particular programming language, one that
+is widely used among developers working in that language.
+
+ The "System Libraries" of an executable work include anything, other
+than the work as a whole, that (a) is included in the normal form of
+packaging a Major Component, but which is not part of that Major
+Component, and (b) serves only to enable use of the work with that
+Major Component, or to implement a Standard Interface for which an
+implementation is available to the public in source code form. A
+"Major Component", in this context, means a major essential component
+(kernel, window system, and so on) of the specific operating system
+(if any) on which the executable work runs, or a compiler used to
+produce the work, or an object code interpreter used to run it.
+
+ The "Corresponding Source" for a work in object code form means all
+the source code needed to generate, install, and (for an executable
+work) run the object code and to modify the work, including scripts to
+control those activities. However, it does not include the work's
+System Libraries, or general-purpose tools or generally available free
+programs which are used unmodified in performing those activities but
+which are not part of the work. For example, Corresponding Source
+includes interface definition files associated with source files for
+the work, and the source code for shared libraries and dynamically
+linked subprograms that the work is specifically designed to require,
+such as by intimate data communication or control flow between those
+subprograms and other parts of the work.
+
+ The Corresponding Source need not include anything that users
+can regenerate automatically from other parts of the Corresponding
+Source.
+
+ The Corresponding Source for a work in source code form is that
+same work.
+
+ 2. Basic Permissions.
+
+ All rights granted under this License are granted for the term of
+copyright on the Program, and are irrevocable provided the stated
+conditions are met. This License explicitly affirms your unlimited
+permission to run the unmodified Program. The output from running a
+covered work is covered by this License only if the output, given its
+content, constitutes a covered work. This License acknowledges your
+rights of fair use or other equivalent, as provided by copyright law.
+
+ You may make, run and propagate covered works that you do not
+convey, without conditions so long as your license otherwise remains
+in force. You may convey covered works to others for the sole purpose
+of having them make modifications exclusively for you, or provide you
+with facilities for running those works, provided that you comply with
+the terms of this License in conveying all material for which you do
+not control copyright. Those thus making or running the covered works
+for you must do so exclusively on your behalf, under your direction
+and control, on terms that prohibit them from making any copies of
+your copyrighted material outside their relationship with you.
+
+ Conveying under any other circumstances is permitted solely under
+the conditions stated below. Sublicensing is not allowed; section 10
+makes it unnecessary.
+
+ 3. Protecting Users' Legal Rights From Anti-Circumvention Law.
+
+ No covered work shall be deemed part of an effective technological
+measure under any applicable law fulfilling obligations under article
+11 of the WIPO copyright treaty adopted on 20 December 1996, or
+similar laws prohibiting or restricting circumvention of such
+measures.
+
+ When you convey a covered work, you waive any legal power to forbid
+circumvention of technological measures to the extent such circumvention
+is effected by exercising rights under this License with respect to
+the covered work, and you disclaim any intention to limit operation or
+modification of the work as a means of enforcing, against the work's
+users, your or third parties' legal rights to forbid circumvention of
+technological measures.
+
+ 4. Conveying Verbatim Copies.
+
+ You may convey 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;
+keep intact all notices stating that this License and any
+non-permissive terms added in accord with section 7 apply to the code;
+keep intact all notices of the absence of any warranty; and give all
+recipients a copy of this License along with the Program.
+
+ You may charge any price or no price for each copy that you convey,
+and you may offer support or warranty protection for a fee.
+
+ 5. Conveying Modified Source Versions.
+
+ You may convey a work based on the Program, or the modifications to
+produce it from the Program, in the form of source code under the
+terms of section 4, provided that you also meet all of these conditions:
+
+ a) The work must carry prominent notices stating that you modified
+ it, and giving a relevant date.
+
+ b) The work must carry prominent notices stating that it is
+ released under this License and any conditions added under section
+ 7. This requirement modifies the requirement in section 4 to
+ "keep intact all notices".
+
+ c) You must license the entire work, as a whole, under this
+ License to anyone who comes into possession of a copy. This
+ License will therefore apply, along with any applicable section 7
+ additional terms, to the whole of the work, and all its parts,
+ regardless of how they are packaged. This License gives no
+ permission to license the work in any other way, but it does not
+ invalidate such permission if you have separately received it.
+
+ d) If the work has interactive user interfaces, each must display
+ Appropriate Legal Notices; however, if the Program has interactive
+ interfaces that do not display Appropriate Legal Notices, your
+ work need not make them do so.
+
+ A compilation of a covered work with other separate and independent
+works, which are not by their nature extensions of the covered work,
+and which are not combined with it such as to form a larger program,
+in or on a volume of a storage or distribution medium, is called an
+"aggregate" if the compilation and its resulting copyright are not
+used to limit the access or legal rights of the compilation's users
+beyond what the individual works permit. Inclusion of a covered work
+in an aggregate does not cause this License to apply to the other
+parts of the aggregate.
+
+ 6. Conveying Non-Source Forms.
+
+ You may convey a covered work in object code form under the terms
+of sections 4 and 5, provided that you also convey the
+machine-readable Corresponding Source under the terms of this License,
+in one of these ways:
+
+ a) Convey the object code in, or embodied in, a physical product
+ (including a physical distribution medium), accompanied by the
+ Corresponding Source fixed on a durable physical medium
+ customarily used for software interchange.
+
+ b) Convey the object code in, or embodied in, a physical product
+ (including a physical distribution medium), accompanied by a
+ written offer, valid for at least three years and valid for as
+ long as you offer spare parts or customer support for that product
+ model, to give anyone who possesses the object code either (1) a
+ copy of the Corresponding Source for all the software in the
+ product that is covered by this License, on a durable physical
+ medium customarily used for software interchange, for a price no
+ more than your reasonable cost of physically performing this
+ conveying of source, or (2) access to copy the
+ Corresponding Source from a network server at no charge.
+
+ c) Convey individual copies of the object code with a copy of the
+ written offer to provide the Corresponding Source. This
+ alternative is allowed only occasionally and noncommercially, and
+ only if you received the object code with such an offer, in accord
+ with subsection 6b.
+
+ d) Convey the object code by offering access from a designated
+ place (gratis or for a charge), and offer equivalent access to the
+ Corresponding Source in the same way through the same place at no
+ further charge. You need not require recipients to copy the
+ Corresponding Source along with the object code. If the place to
+ copy the object code is a network server, the Corresponding Source
+ may be on a different server (operated by you or a third party)
+ that supports equivalent copying facilities, provided you maintain
+ clear directions next to the object code saying where to find the
+ Corresponding Source. Regardless of what server hosts the
+ Corresponding Source, you remain obligated to ensure that it is
+ available for as long as needed to satisfy these requirements.
+
+ e) Convey the object code using peer-to-peer transmission, provided
+ you inform other peers where the object code and Corresponding
+ Source of the work are being offered to the general public at no
+ charge under subsection 6d.
+
+ A separable portion of the object code, whose source code is excluded
+from the Corresponding Source as a System Library, need not be
+included in conveying the object code work.
+
+ A "User Product" is either (1) a "consumer product", which means any
+tangible personal property which is normally used for personal, family,
+or household purposes, or (2) anything designed or sold for incorporation
+into a dwelling. In determining whether a product is a consumer product,
+doubtful cases shall be resolved in favor of coverage. For a particular
+product received by a particular user, "normally used" refers to a
+typical or common use of that class of product, regardless of the status
+of the particular user or of the way in which the particular user
+actually uses, or expects or is expected to use, the product. A product
+is a consumer product regardless of whether the product has substantial
+commercial, industrial or non-consumer uses, unless such uses represent
+the only significant mode of use of the product.
+
+ "Installation Information" for a User Product means any methods,
+procedures, authorization keys, or other information required to install
+and execute modified versions of a covered work in that User Product from
+a modified version of its Corresponding Source. The information must
+suffice to ensure that the continued functioning of the modified object
+code is in no case prevented or interfered with solely because
+modification has been made.
+
+ If you convey an object code work under this section in, or with, or
+specifically for use in, a User Product, and the conveying occurs as
+part of a transaction in which the right of possession and use of the
+User Product is transferred to the recipient in perpetuity or for a
+fixed term (regardless of how the transaction is characterized), the
+Corresponding Source conveyed under this section must be accompanied
+by the Installation Information. But this requirement does not apply
+if neither you nor any third party retains the ability to install
+modified object code on the User Product (for example, the work has
+been installed in ROM).
+
+ The requirement to provide Installation Information does not include a
+requirement to continue to provide support service, warranty, or updates
+for a work that has been modified or installed by the recipient, or for
+the User Product in which it has been modified or installed. Access to a
+network may be denied when the modification itself materially and
+adversely affects the operation of the network or violates the rules and
+protocols for communication across the network.
+
+ Corresponding Source conveyed, and Installation Information provided,
+in accord with this section must be in a format that is publicly
+documented (and with an implementation available to the public in
+source code form), and must require no special password or key for
+unpacking, reading or copying.
+
+ 7. Additional Terms.
+
+ "Additional permissions" are terms that supplement the terms of this
+License by making exceptions from one or more of its conditions.
+Additional permissions that are applicable to the entire Program shall
+be treated as though they were included in this License, to the extent
+that they are valid under applicable law. If additional permissions
+apply only to part of the Program, that part may be used separately
+under those permissions, but the entire Program remains governed by
+this License without regard to the additional permissions.
+
+ When you convey a copy of a covered work, you may at your option
+remove any additional permissions from that copy, or from any part of
+it. (Additional permissions may be written to require their own
+removal in certain cases when you modify the work.) You may place
+additional permissions on material, added by you to a covered work,
+for which you have or can give appropriate copyright permission.
+
+ Notwithstanding any other provision of this License, for material you
+add to a covered work, you may (if authorized by the copyright holders of
+that material) supplement the terms of this License with terms:
+
+ a) Disclaiming warranty or limiting liability differently from the
+ terms of sections 15 and 16 of this License; or
+
+ b) Requiring preservation of specified reasonable legal notices or
+ author attributions in that material or in the Appropriate Legal
+ Notices displayed by works containing it; or
+
+ c) Prohibiting misrepresentation of the origin of that material, or
+ requiring that modified versions of such material be marked in
+ reasonable ways as different from the original version; or
+
+ d) Limiting the use for publicity purposes of names of licensors or
+ authors of the material; or
+
+ e) Declining to grant rights under trademark law for use of some
+ trade names, trademarks, or service marks; or
+
+ f) Requiring indemnification of licensors and authors of that
+ material by anyone who conveys the material (or modified versions of
+ it) with contractual assumptions of liability to the recipient, for
+ any liability that these contractual assumptions directly impose on
+ those licensors and authors.
+
+ All other non-permissive additional terms are considered "further
+restrictions" within the meaning of section 10. If the Program as you
+received it, or any part of it, contains a notice stating that it is
+governed by this License along with a term that is a further
+restriction, you may remove that term. If a license document contains
+a further restriction but permits relicensing or conveying under this
+License, you may add to a covered work material governed by the terms
+of that license document, provided that the further restriction does
+not survive such relicensing or conveying.
+
+ If you add terms to a covered work in accord with this section, you
+must place, in the relevant source files, a statement of the
+additional terms that apply to those files, or a notice indicating
+where to find the applicable terms.
+
+ Additional terms, permissive or non-permissive, may be stated in the
+form of a separately written license, or stated as exceptions;
+the above requirements apply either way.
+
+ 8. Termination.
+
+ You may not propagate or modify a covered work except as expressly
+provided under this License. Any attempt otherwise to propagate or
+modify it is void, and will automatically terminate your rights under
+this License (including any patent licenses granted under the third
+paragraph of section 11).
+
+ However, if you cease all violation of this License, then your
+license from a particular copyright holder is reinstated (a)
+provisionally, unless and until the copyright holder explicitly and
+finally terminates your license, and (b) permanently, if the copyright
+holder fails to notify you of the violation by some reasonable means
+prior to 60 days after the cessation.
+
+ Moreover, your license from a particular copyright holder is
+reinstated permanently if the copyright holder notifies you of the
+violation by some reasonable means, this is the first time you have
+received notice of violation of this License (for any work) from that
+copyright holder, and you cure the violation prior to 30 days after
+your receipt of the notice.
+
+ Termination of your rights under this section does not terminate the
+licenses of parties who have received copies or rights from you under
+this License. If your rights have been terminated and not permanently
+reinstated, you do not qualify to receive new licenses for the same
+material under section 10.
+
+ 9. Acceptance Not Required for Having Copies.
+
+ You are not required to accept this License in order to receive or
+run a copy of the Program. Ancillary propagation of a covered work
+occurring solely as a consequence of using peer-to-peer transmission
+to receive a copy likewise does not require acceptance. However,
+nothing other than this License grants you permission to propagate or
+modify any covered work. These actions infringe copyright if you do
+not accept this License. Therefore, by modifying or propagating a
+covered work, you indicate your acceptance of this License to do so.
+
+ 10. Automatic Licensing of Downstream Recipients.
+
+ Each time you convey a covered work, the recipient automatically
+receives a license from the original licensors, to run, modify and
+propagate that work, subject to this License. You are not responsible
+for enforcing compliance by third parties with this License.
+
+ An "entity transaction" is a transaction transferring control of an
+organization, or substantially all assets of one, or subdividing an
+organization, or merging organizations. If propagation of a covered
+work results from an entity transaction, each party to that
+transaction who receives a copy of the work also receives whatever
+licenses to the work the party's predecessor in interest had or could
+give under the previous paragraph, plus a right to possession of the
+Corresponding Source of the work from the predecessor in interest, if
+the predecessor has it or can get it with reasonable efforts.
+
+ You may not impose any further restrictions on the exercise of the
+rights granted or affirmed under this License. For example, you may
+not impose a license fee, royalty, or other charge for exercise of
+rights granted under this License, and you may not initiate litigation
+(including a cross-claim or counterclaim in a lawsuit) alleging that
+any patent claim is infringed by making, using, selling, offering for
+sale, or importing the Program or any portion of it.
+
+ 11. Patents.
+
+ A "contributor" is a copyright holder who authorizes use under this
+License of the Program or a work on which the Program is based. The
+work thus licensed is called the contributor's "contributor version".
+
+ A contributor's "essential patent claims" are all patent claims
+owned or controlled by the contributor, whether already acquired or
+hereafter acquired, that would be infringed by some manner, permitted
+by this License, of making, using, or selling its contributor version,
+but do not include claims that would be infringed only as a
+consequence of further modification of the contributor version. For
+purposes of this definition, "control" includes the right to grant
+patent sublicenses in a manner consistent with the requirements of
+this License.
+
+ Each contributor grants you a non-exclusive, worldwide, royalty-free
+patent license under the contributor's essential patent claims, to
+make, use, sell, offer for sale, import and otherwise run, modify and
+propagate the contents of its contributor version.
+
+ In the following three paragraphs, a "patent license" is any express
+agreement or commitment, however denominated, not to enforce a patent
+(such as an express permission to practice a patent or covenant not to
+sue for patent infringement). To "grant" such a patent license to a
+party means to make such an agreement or commitment not to enforce a
+patent against the party.
+
+ If you convey a covered work, knowingly relying on a patent license,
+and the Corresponding Source of the work is not available for anyone
+to copy, free of charge and under the terms of this License, through a
+publicly available network server or other readily accessible means,
+then you must either (1) cause the Corresponding Source to be so
+available, or (2) arrange to deprive yourself of the benefit of the
+patent license for this particular work, or (3) arrange, in a manner
+consistent with the requirements of this License, to extend the patent
+license to downstream recipients. "Knowingly relying" means you have
+actual knowledge that, but for the patent license, your conveying the
+covered work in a country, or your recipient's use of the covered work
+in a country, would infringe one or more identifiable patents in that
+country that you have reason to believe are valid.
+
+ If, pursuant to or in connection with a single transaction or
+arrangement, you convey, or propagate by procuring conveyance of, a
+covered work, and grant a patent license to some of the parties
+receiving the covered work authorizing them to use, propagate, modify
+or convey a specific copy of the covered work, then the patent license
+you grant is automatically extended to all recipients of the covered
+work and works based on it.
+
+ A patent license is "discriminatory" if it does not include within
+the scope of its coverage, prohibits the exercise of, or is
+conditioned on the non-exercise of one or more of the rights that are
+specifically granted under this License. You may not convey a covered
+work if you are a party to an arrangement with a third party that is
+in the business of distributing software, under which you make payment
+to the third party based on the extent of your activity of conveying
+the work, and under which the third party grants, to any of the
+parties who would receive the covered work from you, a discriminatory
+patent license (a) in connection with copies of the covered work
+conveyed by you (or copies made from those copies), or (b) primarily
+for and in connection with specific products or compilations that
+contain the covered work, unless you entered into that arrangement,
+or that patent license was granted, prior to 28 March 2007.
+
+ Nothing in this License shall be construed as excluding or limiting
+any implied license or other defenses to infringement that may
+otherwise be available to you under applicable patent law.
+
+ 12. No Surrender of Others' Freedom.
+
+ If 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 convey a
+covered work so as to satisfy simultaneously your obligations under this
+License and any other pertinent obligations, then as a consequence you may
+not convey it at all. For example, if you agree to terms that obligate you
+to collect a royalty for further conveying from those to whom you convey
+the Program, the only way you could satisfy both those terms and this
+License would be to refrain entirely from conveying the Program.
+
+ 13. Use with the GNU Affero General Public License.
+
+ Notwithstanding any other provision of this License, you have
+permission to link or combine any covered work with a work licensed
+under version 3 of the GNU Affero General Public License into a single
+combined work, and to convey the resulting work. The terms of this
+License will continue to apply to the part which is the covered work,
+but the special requirements of the GNU Affero General Public License,
+section 13, concerning interaction through a network will apply to the
+combination as such.
+
+ 14. Revised Versions of this License.
+
+ The Free Software Foundation may publish revised and/or new versions of
+the GNU 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 that a certain numbered version of the GNU General
+Public License "or any later version" applies to it, you have the
+option of following the terms and conditions either of that numbered
+version or of any later version published by the Free Software
+Foundation. If the Program does not specify a version number of the
+GNU General Public License, you may choose any version ever published
+by the Free Software Foundation.
+
+ If the Program specifies that a proxy can decide which future
+versions of the GNU General Public License can be used, that proxy's
+public statement of acceptance of a version permanently authorizes you
+to choose that version for the Program.
+
+ Later license versions may give you additional or different
+permissions. However, no additional obligations are imposed on any
+author or copyright holder as a result of your choosing to follow a
+later version.
+
+ 15. Disclaimer of Warranty.
+
+ 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.
+
+ 16. Limitation of Liability.
+
+ IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
+WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MODIFIES AND/OR CONVEYS
+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.
+
+ 17. Interpretation of Sections 15 and 16.
+
+ If the disclaimer of warranty and limitation of liability provided
+above cannot be given local legal effect according to their terms,
+reviewing courts shall apply local law that most closely approximates
+an absolute waiver of all civil liability in connection with the
+Program, unless a warranty or assumption of liability accompanies a
+copy of the Program in return for a fee.
+
+ 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
+state 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 3 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, see <http://www.gnu.org/licenses/>.
+
+Also add information on how to contact you by electronic and paper mail.
+
+ If the program does terminal interaction, make it output a short
+notice like this when it starts in an interactive mode:
+
+ <program> Copyright (C) <year> <name of author>
+ This program 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, your program's commands
+might be different; for a GUI interface, you would use an "about box".
+
+ You should also get your employer (if you work as a programmer) or school,
+if any, to sign a "copyright disclaimer" for the program, if necessary.
+For more information on this, and how to apply and follow the GNU GPL, see
+<http://www.gnu.org/licenses/>.
+
+ The GNU 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. But first, please read
+<http://www.gnu.org/philosophy/why-not-lgpl.html>.

- GNU GENERAL PUBLIC LICENSE\r
- Version 2, June 1991\r
-\r
- Copyright (C) 1989, 1991 Free Software Foundation, Inc.\r
- 675 Mass Ave, Cambridge, MA 02139, USA\r
- Everyone is permitted to copy and distribute verbatim copies\r
- of this license document, but changing it is not allowed.\r
-\r
- Preamble\r
-\r
- The licenses for most software are designed to take away your\r
-freedom to share and change it. By contrast, the GNU General Public\r
-License is intended to guarantee your freedom to share and change free\r
-software--to make sure the software is free for all its users. This\r
-General Public License applies to most of the Free Software\r
-Foundation's software and to any other program whose authors commit to\r
-using it. (Some other Free Software Foundation software is covered by\r
-the GNU Library General Public License instead.) You can apply it to\r
-your programs, too.\r
-\r
- When we speak of free software, we are referring to freedom, not\r
-price. Our General Public Licenses are designed to make sure that you\r
-have the freedom to distribute copies of free software (and charge for\r
-this service if you wish), that you receive source code or can get it\r
-if you want it, that you can change the software or use pieces of it\r
-in new free programs; and that you know you can do these things.\r
-\r
- To protect your rights, we need to make restrictions that forbid\r
-anyone to deny you these rights or to ask you to surrender the rights.\r
-These restrictions translate to certain responsibilities for you if you\r
-distribute copies of the software, or if you modify it.\r
-\r
- For example, if you distribute copies of such a program, whether\r
-gratis or for a fee, you must give the recipients all the rights that\r
-you have. You must make sure that they, too, receive or can get the\r
-source code. And you must show them these terms so they know their\r
-rights.\r
-\r
- We protect your rights with two steps: (1) copyright the software, and\r
-(2) offer you this license which gives you legal permission to copy,\r
-distribute and/or modify the software.\r
-\r
- Also, for each author's protection and ours, we want to make certain\r
-that everyone understands that there is no warranty for this free\r
-software. If the software is modified by someone else and passed on, we\r
-want its recipients to know that what they have is not the original, so\r
-that any problems introduced by others will not reflect on the original\r
-authors' reputations.\r
-\r
- Finally, any free program is threatened constantly by software\r
-patents. We wish to avoid the danger that redistributors of a free\r
-program will individually obtain patent licenses, in effect making the\r
-program proprietary. To prevent this, we have made it clear that any\r
-patent must be licensed for everyone's free use or not licensed at all.\r
-\r
- The precise terms and conditions for copying, distribution and\r
-modification follow.\r
-\f\r
- GNU GENERAL PUBLIC LICENSE\r
- TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION\r
-\r
- 0. This License applies to any program or other work which contains\r
-a notice placed by the copyright holder saying it may be distributed\r
-under the terms of this General Public License. The "Program", below,\r
-refers to any such program or work, and a "work based on the Program"\r
-means either the Program or any derivative work under copyright law:\r
-that is to say, a work containing the Program or a portion of it,\r
-either verbatim or with modifications and/or translated into another\r
-language. (Hereinafter, translation is included without limitation in\r
-the term "modification".) Each licensee is addressed as "you".\r
-\r
-Activities other than copying, distribution and modification are not\r
-covered by this License; they are outside its scope. The act of\r
-running the Program is not restricted, and the output from the Program\r
-is covered only if its contents constitute a work based on the\r
-Program (independent of having been made by running the Program).\r
-Whether that is true depends on what the Program does.\r
-\r
- 1. You may copy and distribute verbatim copies of the Program's\r
-source code as you receive it, in any medium, provided that you\r
-conspicuously and appropriately publish on each copy an appropriate\r
-copyright notice and disclaimer of warranty; keep intact all the\r
-notices that refer to this License and to the absence of any warranty;\r
-and give any other recipients of the Program a copy of this License\r
-along with the Program.\r
-\r
-You may charge a fee for the physical act of transferring a copy, and\r
-you may at your option offer warranty protection in exchange for a fee.\r
-\r
- 2. You may modify your copy or copies of the Program or any portion\r
-of it, thus forming a work based on the Program, and copy and\r
-distribute such modifications or work under the terms of Section 1\r
-above, provided that you also meet all of these conditions:\r
-\r
- a) You must cause the modified files to carry prominent notices\r
- stating that you changed the files and the date of any change.\r
-\r
- b) You must cause any work that you distribute or publish, that in\r
- whole or in part contains or is derived from the Program or any\r
- part thereof, to be licensed as a whole at no charge to all third\r
- parties under the terms of this License.\r
-\r
- c) If the modified program normally reads commands interactively\r
- when run, you must cause it, when started running for such\r
- interactive use in the most ordinary way, to print or display an\r
- announcement including an appropriate copyright notice and a\r
- notice that there is no warranty (or else, saying that you provide\r
- a warranty) and that users may redistribute the program under\r
- these conditions, and telling the user how to view a copy of this\r
- License. (Exception: if the Program itself is interactive but\r
- does not normally print such an announcement, your work based on\r
- the Program is not required to print an announcement.)\r
-\f\r
-These requirements apply to the modified work as a whole. If\r
-identifiable sections of that work are not derived from the Program,\r
-and can be reasonably considered independent and separate works in\r
-themselves, then this License, and its terms, do not apply to those\r
-sections when you distribute them as separate works. But when you\r
-distribute the same sections as part of a whole which is a work based\r
-on the Program, the distribution of the whole must be on the terms of\r
-this License, whose permissions for other licensees extend to the\r
-entire whole, and thus to each and every part regardless of who wrote it.\r
-\r
-Thus, it is not the intent of this section to claim rights or contest\r
-your rights to work written entirely by you; rather, the intent is to\r
-exercise the right to control the distribution of derivative or\r
-collective works based on the Program.\r
-\r
-In addition, mere aggregation of another work not based on the Program\r
-with the Program (or with a work based on the Program) on a volume of\r
-a storage or distribution medium does not bring the other work under\r
-the scope of this License.\r
-\r
- 3. You may copy and distribute the Program (or a work based on it,\r
-under Section 2) in object code or executable form under the terms of\r
-Sections 1 and 2 above provided that you also do one of the following:\r
-\r
- a) Accompany it with the complete corresponding machine-readable\r
- source code, which must be distributed under the terms of Sections\r
- 1 and 2 above on a medium customarily used for software interchange; or,\r
-\r
- b) Accompany it with a written offer, valid for at least three\r
- years, to give any third party, for a charge no more than your\r
- cost of physically performing source distribution, a complete\r
- machine-readable copy of the corresponding source code, to be\r
- distributed under the terms of Sections 1 and 2 above on a medium\r
- customarily used for software interchange; or,\r
-\r
- c) Accompany it with the information you received as to the offer\r
- to distribute corresponding source code. (This alternative is\r
- allowed only for noncommercial distribution and only if you\r
- received the program in object code or executable form with such\r
- an offer, in accord with Subsection b above.)\r
-\r
-The source code for a work means the preferred form of the work for\r
-making modifications to it. For an executable work, complete source\r
-code means all the source code for all modules it contains, plus any\r
-associated interface definition files, plus the scripts used to\r
-control compilation and installation of the executable. However, as a\r
-special exception, the source code distributed need not include\r
-anything that is normally distributed (in either source or binary\r
-form) with the major components (compiler, kernel, and so on) of the\r
-operating system on which the executable runs, unless that component\r
-itself accompanies the executable.\r
-\r
-If distribution of executable or object code is made by offering\r
-access to copy from a designated place, then offering equivalent\r
-access to copy the source code from the same place counts as\r
-distribution of the source code, even though third parties are not\r
-compelled to copy the source along with the object code.\r
-\f\r
- 4. You may not copy, modify, sublicense, or distribute the Program\r
-except as expressly provided under this License. Any attempt\r
-otherwise to copy, modify, sublicense or distribute the Program is\r
-void, and will automatically terminate your rights under this License.\r
-However, parties who have received copies, or rights, from you under\r
-this License will not have their licenses terminated so long as such\r
-parties remain in full compliance.\r
-\r
- 5. You are not required to accept this License, since you have not\r
-signed it. However, nothing else grants you permission to modify or\r
-distribute the Program or its derivative works. These actions are\r
-prohibited by law if you do not accept this License. Therefore, by\r
-modifying or distributing the Program (or any work based on the\r
-Program), you indicate your acceptance of this License to do so, and\r
-all its terms and conditions for copying, distributing or modifying\r
-the Program or works based on it.\r
-\r
- 6. Each time you redistribute the Program (or any work based on the\r
-Program), the recipient automatically receives a license from the\r
-original licensor to copy, distribute or modify the Program subject to\r
-these terms and conditions. You may not impose any further\r
-restrictions on the recipients' exercise of the rights granted herein.\r
-You are not responsible for enforcing compliance by third parties to\r
-this License.\r
-\r
- 7. If, as a consequence of a court judgment or allegation of patent\r
-infringement or for any other reason (not limited to patent issues),\r
-conditions are imposed on you (whether by court order, agreement or\r
-otherwise) that contradict the conditions of this License, they do not\r
-excuse you from the conditions of this License. If you cannot\r
-distribute so as to satisfy simultaneously your obligations under this\r
-License and any other pertinent obligations, then as a consequence you\r
-may not distribute the Program at all. For example, if a patent\r
-license would not permit royalty-free redistribution of the Program by\r
-all those who receive copies directly or indirectly through you, then\r
-the only way you could satisfy both it and this License would be to\r
-refrain entirely from distribution of the Program.\r
-\r
-If any portion of this section is held invalid or unenforceable under\r
-any particular circumstance, the balance of the section is intended to\r
-apply and the section as a whole is intended to apply in other\r
-circumstances.\r
-\r
-It is not the purpose of this section to induce you to infringe any\r
-patents or other property right claims or to contest validity of any\r
-such claims; this section has the sole purpose of protecting the\r
-integrity of the free software distribution system, which is\r
-implemented by public license practices. Many people have made\r
-generous contributions to the wide range of software distributed\r
-through that system in reliance on consistent application of that\r
-system; it is up to the author/donor to decide if he or she is willing\r
-to distribute software through any other system and a licensee cannot\r
-impose that choice.\r
-\r
-This section is intended to make thoroughly clear what is believed to\r
-be a consequence of the rest of this License.\r
-\f\r
- 8. If the distribution and/or use of the Program is restricted in\r
-certain countries either by patents or by copyrighted interfaces, the\r
-original copyright holder who places the Program under this License\r
-may add an explicit geographical distribution limitation excluding\r
-those countries, so that distribution is permitted only in or among\r
-countries not thus excluded. In such case, this License incorporates\r
-the limitation as if written in the body of this License.\r
-\r
- 9. The Free Software Foundation may publish revised and/or new versions\r
-of the General Public License from time to time. Such new versions will\r
-be similar in spirit to the present version, but may differ in detail to\r
-address new problems or concerns.\r
-\r
-Each version is given a distinguishing version number. If the Program\r
-specifies a version number of this License which applies to it and "any\r
-later version", you have the option of following the terms and conditions\r
-either of that version or of any later version published by the Free\r
-Software Foundation. If the Program does not specify a version number of\r
-this License, you may choose any version ever published by the Free Software\r
-Foundation.\r
-\r
- 10. If you wish to incorporate parts of the Program into other free\r
-programs whose distribution conditions are different, write to the author\r
-to ask for permission. For software which is copyrighted by the Free\r
-Software Foundation, write to the Free Software Foundation; we sometimes\r
-make exceptions for this. Our decision will be guided by the two goals\r
-of preserving the free status of all derivatives of our free software and\r
-of promoting the sharing and reuse of software generally.\r
-\r
- NO WARRANTY\r
-\r
- 11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY\r
-FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW. EXCEPT WHEN\r
-OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES\r
-PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED\r
-OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF\r
-MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. THE ENTIRE RISK AS\r
-TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU. SHOULD THE\r
-PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING,\r
-REPAIR OR CORRECTION.\r
-\r
- 12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING\r
-WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR\r
-REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES,\r
-INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING\r
-OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED\r
-TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY\r
-YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER\r
-PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE\r
-POSSIBILITY OF SUCH DAMAGES.\r
-\r
- END OF TERMS AND CONDITIONS\r
-\f\r
- Appendix: How to Apply These Terms to Your New Programs\r
-\r
- If you develop a new program, and you want it to be of the greatest\r
-possible use to the public, the best way to achieve this is to make it\r
-free software which everyone can redistribute and change under these terms.\r
-\r
- To do so, attach the following notices to the program. It is safest\r
-to attach them to the start of each source file to most effectively\r
-convey the exclusion of warranty; and each file should have at least\r
-the "copyright" line and a pointer to where the full notice is found.\r
-\r
- <one line to give the program's name and a brief idea of what it does.>\r
- Copyright (C) 19yy <name of author>\r
-\r
- This program is free software; you can redistribute it and/or modify\r
- it under the terms of the GNU General Public License as published by\r
- the Free Software Foundation; either version 2 of the License, or\r
- (at your option) any later version.\r
-\r
- This program is distributed in the hope that it will be useful,\r
- but WITHOUT ANY WARRANTY; without even the implied warranty of\r
- MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the\r
- GNU General Public License for more details.\r
-\r
- You should have received a copy of the GNU General Public License\r
- along with this program; if not, write to the Free Software\r
- Foundation, Inc., 675 Mass Ave, Cambridge, MA 02139, USA.\r
-\r
-Also add information on how to contact you by electronic and paper mail.\r
-\r
-If the program is interactive, make it output a short notice like this\r
-when it starts in an interactive mode:\r
-\r
- Gnomovision version 69, Copyright (C) 19yy name of author\r
- Gnomovision comes with ABSOLUTELY NO WARRANTY; for details type `show w'.\r
- This is free software, and you are welcome to redistribute it\r
- under certain conditions; type `show c' for details.\r
-\r
-The hypothetical commands `show w' and `show c' should show the appropriate\r
-parts of the General Public License. Of course, the commands you use may\r
-be called something other than `show w' and `show c'; they could even be\r
-mouse-clicks or menu items--whatever suits your program.\r
-\r
-You should also get your employer (if you work as a programmer) or your\r
-school, if any, to sign a "copyright disclaimer" for the program, if\r
-necessary. Here is a sample; alter the names:\r
-\r
- Yoyodyne, Inc., hereby disclaims all copyright interest in the program\r
- `Gnomovision' (which makes passes at compilers) written by James Hacker.\r
-\r
- <signature of Ty Coon>, 1 April 1989\r
- Ty Coon, President of Vice\r
-\r
-This General Public License does not permit incorporating your program into\r
-proprietary programs. If your program is a subroutine library, you may\r
-consider it more useful to permit linking proprietary applications with the\r
-library. If this is what you want to do, use the GNU Library General\r
-Public License instead of this License.\r

+in new free programs; and that you know you can do these things.\r
+\r
+ To protect your rights, we need to make restrictions that forbid\r
+anyone to deny you these rights or to ask you to surrender the rights.\r
+These restrictions translate to certain responsibilities for you if you\r
+distribute copies of the software, or if you modify it.\r
+\r
+ For example, if you distribute copies of such a program, whether\r
+gratis or for a fee, you must give the recipients all the rights that\r
+you have. You must make sure that they, too, receive or can get the\r
+source code. And you must show them these terms so they know their\r
+rights.\r
+\r
+ We protect your rights with two steps: (1) copyright the software, and\r
+(2) offer you this license which gives you legal permission to copy,\r
+distribute and/or modify the software.\r
+\r
+ Also, for each author's protection and ours, we want to make certain\r
+that everyone understands that there is no warranty for this free\r
+software. If the software is modified by someone else and passed on, we\r
+want its recipients to know that what they have is not the original, so\r
+that any problems introduced by others will not reflect on the original\r
+authors' reputations.\r
+\r
+ Finally, any free program is threatened constantly by software\r
+patents. We wish to avoid the danger that redistributors of a free\r
+program will individually obtain patent licenses, in effect making the\r
+program proprietary. To prevent this, we have made it clear that any\r
+patent must be licensed for everyone's free use or not licensed at all.\r
+\r
+ The precise terms and conditions for copying, distribution and\r
+modification follow.\r
+\f\r
+ GNU GENERAL PUBLIC LICENSE\r
+ TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION\r
+\r
+ 0. This License applies to any program or other work which contains\r
+a notice placed by the copyright holder saying it may be distributed\r
+under the terms of this General Public License. The "Program", below,\r
+refers to any such program or work, and a "work based on the Program"\r
+means either the Program or any derivative work under copyright law:\r
+that is to say, a work containing the Program or a portion of it,\r
+either verbatim or with modifications and/or translated into another\r
+language. (Hereinafter, translation is included without limitation in\r
+the term "modification".) Each licensee is addressed as "you".\r
+\r
+Activities other than copying, distribution and modification are not\r
+covered by this License; they are outside its scope. The act of\r
+running the Program is not restricted, and the output from the Program\r
+is covered only if its contents constitute a work based on the\r
+Program (independent of having been made by running the Program).\r
+Whether that is true depends on what the Program does.\r
+\r
+ 1. You may copy and distribute verbatim copies of the Program's\r
+source code as you receive it, in any medium, provided that you\r
+conspicuously and appropriately publish on each copy an appropriate\r
+copyright notice and disclaimer of warranty; keep intact all the\r
+notices that refer to this License and to the absence of any warranty;\r
+and give any other recipients of the Program a copy of this License\r
+along with the Program.\r
+\r
+You may charge a fee for the physical act of transferring a copy, and\r
+you may at your option offer warranty protection in exchange for a fee.\r
+\r
+ 2. You may modify your copy or copies of the Program or any portion\r
+of it, thus forming a work based on the Program, and copy and\r
+distribute such modifications or work under the terms of Section 1\r
+above, provided that you also meet all of these conditions:\r
+\r
+ a) You must cause the modified files to carry prominent notices\r
+ stating that you changed the files and the date of any change.\r
+\r
+ b) You must cause any work that you distribute or publish, that in\r
+ whole or in part contains or is derived from the Program or any\r
+ part thereof, to be licensed as a whole at no charge to all third\r
+ parties under the terms of this License.\r
+\r
+ c) If the modified program normally reads commands interactively\r
+ when run, you must cause it, when started running for such\r
+ interactive use in the most ordinary way, to print or display an\r
+ announcement including an appropriate copyright notice and a\r
+ notice that there is no warranty (or else, saying that you provide\r
+ a warranty) and that users may redistribute the program under\r
+ these conditions, and telling the user how to view a copy of this\r
+ License. (Exception: if the Program itself is interactive but\r
+ does not normally print such an announcement, your work based on\r
+ the Program is not required to print an announcement.)\r
+\f\r
+These requirements apply to the modified work as a whole. If\r
+identifiable sections of that work are not derived from the Program,\r
+and can be reasonably considered independent and separate works in\r
+themselves, then this License, and its terms, do not apply to those\r
+sections when you distribute them as separate works. But when you\r
+distribute the same sections as part of a whole which is a work based\r
+on the Program, the distribution of the whole must be on the terms of\r
+this License, whose permissions for other licensees extend to the\r
+entire whole, and thus to each and every part regardless of who wrote it.\r
+\r
+Thus, it is not the intent of this section to claim rights or contest\r
+your rights to work written entirely by you; rather, the intent is to\r
+exercise the right to control the distribution of derivative or\r
+collective works based on the Program.\r
+\r
+In addition, mere aggregation of another work not based on the Program\r
+with the Program (or with a work based on the Program) on a volume of\r
+a storage or distribution medium does not bring the other work under\r
+the scope of this License.\r
+\r
+ 3. You may copy and distribute the Program (or a work based on it,\r
+under Section 2) in object code or executable form under the terms of\r
+Sections 1 and 2 above provided that you also do one of the following:\r
+\r
+ a) Accompany it with the complete corresponding machine-readable\r
+ source code, which must be distributed under the terms of Sections\r
+ 1 and 2 above on a medium customarily used for software interchange; or,\r
+\r
+ b) Accompany it with a written offer, valid for at least three\r
+ years, to give any third party, for a charge no more than your\r
+ cost of physically performing source distribution, a complete\r
+ machine-readable copy of the corresponding source code, to be\r
+ distributed under the terms of Sections 1 and 2 above on a medium\r
+ customarily used for software interchange; or,\r
+\r
+ c) Accompany it with the information you received as to the offer\r
+ to distribute corresponding source code. (This alternative is\r
+ allowed only for noncommercial distribution and only if you\r
+ received the program in object code or executable form with such\r
+ an offer, in accord with Subsection b above.)\r
+\r
+The source code for a work means the preferred form of the work for\r
+making modifications to it. For an executable work, complete source\r
+code means all the source code for all modules it contains, plus any\r
+associated interface definition files, plus the scripts used to\r
+control compilation and installation of the executable. However, as a\r
+special exception, the source code distributed need not include\r
+anything that is normally distributed (in either source or binary\r
+form) with the major components (compiler, kernel, and so on) of the\r
+operating system on which the executable runs, unless that component\r
+itself accompanies the executable.\r
+\r
+If distribution of executable or object code is made by offering\r
+access to copy from a designated place, then offering equivalent\r
+access to copy the source code from the same place counts as\r
+distribution of the source code, even though third parties are not\r
+compelled to copy the source along with the object code.\r
+\f\r
+ 4. You may not copy, modify, sublicense, or distribute the Program\r
+except as expressly provided under this License. Any attempt\r
+otherwise to copy, modify, sublicense or distribute the Program is\r
+void, and will automatically terminate your rights under this License.\r
+However, parties who have received copies, or rights, from you under\r
+this License will not have their licenses terminated so long as such\r
+parties remain in full compliance.\r
+\r
+ 5. You are not required to accept this License, since you have not\r
+signed it. However, nothing else grants you permission to modify or\r
+distribute the Program or its derivative works. These actions are\r
+prohibited by law if you do not accept this License. Therefore, by\r
+modifying or distributing the Program (or any work based on the\r
+Program), you indicate your acceptance of this License to do so, and\r
+all its terms and conditions for copying, distributing or modifying\r
+the Program or works based on it.\r
+\r
+ 6. Each time you redistribute the Program (or any work based on the\r
+Program), the recipient automatically receives a license from the\r
+original licensor to copy, distribute or modify the Program subject to\r
+these terms and conditions. You may not impose any further\r
+restrictions on the recipients' exercise of the rights granted herein.\r
+You are not responsible for enforcing compliance by third parties to\r
+this License.\r
+\r
+ 7. If, as a consequence of a court judgment or allegation of patent\r
+infringement or for any other reason (not limited to patent issues),\r
+conditions are imposed on you (whether by court order, agreement or\r
+otherwise) that contradict the conditions of this License, they do not\r
+excuse you from the conditions of this License. If you cannot\r
+distribute so as to satisfy simultaneously your obligations under this\r
+License and any other pertinent obligations, then as a consequence you\r
+may not distribute the Program at all. For example, if a patent\r
+license would not permit royalty-free redistribution of the Program by\r
+all those who receive copies directly or indirectly through you, then\r
+the only way you could satisfy both it and this License would be to\r
+refrain entirely from distribution of the Program.\r
+\r
+If any portion of this section is held invalid or unenforceable under\r
+any particular circumstance, the balance of the section is intended to\r
+apply and the section as a whole is intended to apply in other\r
+circumstances.\r
+\r
+It is not the purpose of this section to induce you to infringe any\r
+patents or other property right claims or to contest validity of any\r
+such claims; this section has the sole purpose of protecting the\r
+integrity of the free software distribution system, which is\r
+implemented by public license practices. Many people have made\r
+generous contributions to the wide range of software distributed\r
+through that system in reliance on consistent application of that\r
+system; it is up to the author/donor to decide if he or she is willing\r
+to distribute software through any other system and a licensee cannot\r
+impose that choice.\r
+\r
+This section is intended to make thoroughly clear what is believed to\r
+be a consequence of the rest of this License.\r
+\f\r
+ 8. If the distribution and/or use of the Program is restricted in\r
+certain countries either by patents or by copyrighted interfaces, the\r
+original copyright holder who places the Program under this License\r
+may add an explicit geographical distribution limitation excluding\r
+those countries, so that distribution is permitted only in or among\r
+countries not thus excluded. In such case, this License incorporates\r
+the limitation as if written in the body of this License.\r
+\r
+ 9. The Free Software Foundation may publish revised and/or new versions\r
+of the General Public License from time to time. Such new versions will\r
+be similar in spirit to the present version, but may differ in detail to\r
+address new problems or concerns.\r
+\r
+Each version is given a distinguishing version number. If the Program\r
+specifies a version number of this License which applies to it and "any\r
+later version", you have the option of following the terms and conditions\r
+either of that version or of any later version published by the Free\r
+Software Foundation. If the Program does not specify a version number of\r
+this License, you may choose any version ever published by the Free Software\r
+Foundation.\r
+\r
+ 10. If you wish to incorporate parts of the Program into other free\r
+programs whose distribution conditions are different, write to the author\r
+to ask for permission. For software which is copyrighted by the Free\r
+Software Foundation, write to the Free Software Foundation; we sometimes\r
+make exceptions for this. Our decision will be guided by the two goals\r
+of preserving the free status of all derivatives of our free software and\r
+of promoting the sharing and reuse of software generally.\r
+\r
+ NO WARRANTY\r
+\r
+ 11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY\r
+FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW. EXCEPT WHEN\r
+OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES\r
+PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED\r
+OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF\r
+MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. THE ENTIRE RISK AS\r
+TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU. SHOULD THE\r
+PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING,\r
+REPAIR OR CORRECTION.\r
+\r
+ 12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING\r
+WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR\r
+REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES,\r
+INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING\r
+OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED\r
+TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY\r
+YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER\r
+PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE\r
+POSSIBILITY OF SUCH DAMAGES.\r
+\r
+ END OF TERMS AND CONDITIONS\r
+\f\r
+ Appendix: How to Apply These Terms to Your New Programs\r
+\r
+ If you develop a new program, and you want it to be of the greatest\r
+possible use to the public, the best way to achieve this is to make it\r
+free software which everyone can redistribute and change under these terms.\r
+\r
+ To do so, attach the following notices to the program. It is safest\r
+to attach them to the start of each source file to most effectively\r
+convey the exclusion of warranty; and each file should have at least\r
+the "copyright" line and a pointer to where the full notice is found.\r
+\r
+ <one line to give the program's name and a brief idea of what it does.>\r
+ Copyright (C) 19yy <name of author>\r
+\r
+ This program is free software; you can redistribute it and/or modify\r
+ it under the terms of the GNU General Public License as published by\r
+ the Free Software Foundation; either version 2 of the License, or\r
+ (at your option) any later version.\r
+\r
+ This program is distributed in the hope that it will be useful,\r
+ but WITHOUT ANY WARRANTY; without even the implied warranty of\r
+ MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the\r
+ GNU General Public License for more details.\r
+\r
+ You should have received a copy of the GNU General Public License\r
+ along with this program; if not, write to the Free Software\r
+ Foundation, Inc., 675 Mass Ave, Cambridge, MA 02139, USA.\r
+\r
+Also add information on how to contact you by electronic and paper mail.\r
+\r
+If the program is interactive, make it output a short notice like this\r
+when it starts in an interactive mode:\r
+\r
+ Gnomovision version 69, Copyright (C) 19yy name of author\r
+ Gnomovision comes with ABSOLUTELY NO WARRANTY; for details type `show w'.\r
+ This is free software, and you are welcome to redistribute it\r
+ under certain conditions; type `show c' for details.\r
+\r
+The hypothetical commands `show w' and `show c' should show the appropriate\r
+parts of the General Public License. Of course, the commands you use may\r
+be called something other than `show w' and `show c'; they could even be\r
+mouse-clicks or menu items--whatever suits your program.\r
+\r
+You should also get your employer (if you work as a programmer) or your\r
+school, if any, to sign a "copyright disclaimer" for the program, if\r
+necessary. Here is a sample; alter the names:\r
+\r
+ Yoyodyne, Inc., hereby disclaims all copyright interest in the program\r
+ `Gnomovision' (which makes passes at compilers) written by James Hacker.\r
+\r
+ <signature of Ty Coon>, 1 April 1989\r

+\r
+This General Public License does not permit incorporating your program into\r
+proprietary programs. If your program is a subroutine library, you may\r
+consider it more useful to permit linking proprietary applications with the\r
+library. If this is what you want to do, use the GNU Library General\r
+Public License instead of this License.\r
--- /dev/null
+ GNU GENERAL PUBLIC LICENSE
+ Version 3, 29 June 2007
+
+ Copyright (C) 2007 Free Software Foundation, Inc. <http://fsf.org/>
+ Everyone is permitted to copy and distribute verbatim copies
+ of this license document, but changing it is not allowed.
+
+ Preamble
+
+ The GNU General Public License is a free, copyleft license for
+software and other kinds of works.
+
+ The licenses for most software and other practical works are designed
+to take away your freedom to share and change the works. By contrast,
+the GNU General Public License is intended to guarantee your freedom to
+share and change all versions of a program--to make sure it remains free
+software for all its users. We, the Free Software Foundation, use the
+GNU General Public License for most of our software; it applies also to
+any other work released this way by its authors. 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
+them 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 prevent others from denying you
+these rights or asking you to surrender the rights. Therefore, you have
+certain responsibilities if you distribute copies of the software, or if
+you modify it: responsibilities to respect the freedom of others.
+
+ For example, if you distribute copies of such a program, whether
+gratis or for a fee, you must pass on to the recipients the same
+freedoms that you received. 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.
+
+ Developers that use the GNU GPL protect your rights with two steps:
+(1) assert copyright on the software, and (2) offer you this License
+giving you legal permission to copy, distribute and/or modify it.
+
+ For the developers' and authors' protection, the GPL clearly explains
+that there is no warranty for this free software. For both users' and
+authors' sake, the GPL requires that modified versions be marked as
+changed, so that their problems will not be attributed erroneously to
+authors of previous versions.
+
+ Some devices are designed to deny users access to install or run
+modified versions of the software inside them, although the manufacturer
+can do so. This is fundamentally incompatible with the aim of
+protecting users' freedom to change the software. The systematic
+pattern of such abuse occurs in the area of products for individuals to
+use, which is precisely where it is most unacceptable. Therefore, we
+have designed this version of the GPL to prohibit the practice for those
+products. If such problems arise substantially in other domains, we
+stand ready to extend this provision to those domains in future versions
+of the GPL, as needed to protect the freedom of users.
+
+ Finally, every program is threatened constantly by software patents.
+States should not allow patents to restrict development and use of
+software on general-purpose computers, but in those that do, we wish to
+avoid the special danger that patents applied to a free program could
+make it effectively proprietary. To prevent this, the GPL assures that
+patents cannot be used to render the program non-free.
+
+ The precise terms and conditions for copying, distribution and
+modification follow.
+
+ TERMS AND CONDITIONS
+
+ 0. Definitions.
+
+ "This License" refers to version 3 of the GNU General Public License.
+
+ "Copyright" also means copyright-like laws that apply to other kinds of
+works, such as semiconductor masks.
+
+ "The Program" refers to any copyrightable work licensed under this
+License. Each licensee is addressed as "you". "Licensees" and
+"recipients" may be individuals or organizations.
+
+ To "modify" a work means to copy from or adapt all or part of the work
+in a fashion requiring copyright permission, other than the making of an
+exact copy. The resulting work is called a "modified version" of the
+earlier work or a work "based on" the earlier work.
+
+ A "covered work" means either the unmodified Program or a work based
+on the Program.
+
+ To "propagate" a work means to do anything with it that, without
+permission, would make you directly or secondarily liable for
+infringement under applicable copyright law, except executing it on a
+computer or modifying a private copy. Propagation includes copying,
+distribution (with or without modification), making available to the
+public, and in some countries other activities as well.
+
+ To "convey" a work means any kind of propagation that enables other
+parties to make or receive copies. Mere interaction with a user through
+a computer network, with no transfer of a copy, is not conveying.
+
+ An interactive user interface displays "Appropriate Legal Notices"
+to the extent that it includes a convenient and prominently visible
+feature that (1) displays an appropriate copyright notice, and (2)
+tells the user that there is no warranty for the work (except to the
+extent that warranties are provided), that licensees may convey the
+work under this License, and how to view a copy of this License. If
+the interface presents a list of user commands or options, such as a
+menu, a prominent item in the list meets this criterion.
+
+ 1. Source Code.
+
+ The "source code" for a work means the preferred form of the work
+for making modifications to it. "Object code" means any non-source
+form of a work.
+
+ A "Standard Interface" means an interface that either is an official
+standard defined by a recognized standards body, or, in the case of
+interfaces specified for a particular programming language, one that
+is widely used among developers working in that language.
+
+ The "System Libraries" of an executable work include anything, other
+than the work as a whole, that (a) is included in the normal form of
+packaging a Major Component, but which is not part of that Major
+Component, and (b) serves only to enable use of the work with that
+Major Component, or to implement a Standard Interface for which an
+implementation is available to the public in source code form. A
+"Major Component", in this context, means a major essential component
+(kernel, window system, and so on) of the specific operating system
+(if any) on which the executable work runs, or a compiler used to
+produce the work, or an object code interpreter used to run it.
+
+ The "Corresponding Source" for a work in object code form means all
+the source code needed to generate, install, and (for an executable
+work) run the object code and to modify the work, including scripts to
+control those activities. However, it does not include the work's
+System Libraries, or general-purpose tools or generally available free
+programs which are used unmodified in performing those activities but
+which are not part of the work. For example, Corresponding Source
+includes interface definition files associated with source files for
+the work, and the source code for shared libraries and dynamically
+linked subprograms that the work is specifically designed to require,
+such as by intimate data communication or control flow between those
+subprograms and other parts of the work.
+
+ The Corresponding Source need not include anything that users
+can regenerate automatically from other parts of the Corresponding
+Source.
+
+ The Corresponding Source for a work in source code form is that
+same work.
+
+ 2. Basic Permissions.
+
+ All rights granted under this License are granted for the term of
+copyright on the Program, and are irrevocable provided the stated
+conditions are met. This License explicitly affirms your unlimited
+permission to run the unmodified Program. The output from running a
+covered work is covered by this License only if the output, given its
+content, constitutes a covered work. This License acknowledges your
+rights of fair use or other equivalent, as provided by copyright law.
+
+ You may make, run and propagate covered works that you do not
+convey, without conditions so long as your license otherwise remains
+in force. You may convey covered works to others for the sole purpose
+of having them make modifications exclusively for you, or provide you
+with facilities for running those works, provided that you comply with
+the terms of this License in conveying all material for which you do
+not control copyright. Those thus making or running the covered works
+for you must do so exclusively on your behalf, under your direction
+and control, on terms that prohibit them from making any copies of
+your copyrighted material outside their relationship with you.
+
+ Conveying under any other circumstances is permitted solely under
+the conditions stated below. Sublicensing is not allowed; section 10
+makes it unnecessary.
+
+ 3. Protecting Users' Legal Rights From Anti-Circumvention Law.
+
+ No covered work shall be deemed part of an effective technological
+measure under any applicable law fulfilling obligations under article
+11 of the WIPO copyright treaty adopted on 20 December 1996, or
+similar laws prohibiting or restricting circumvention of such
+measures.
+
+ When you convey a covered work, you waive any legal power to forbid
+circumvention of technological measures to the extent such circumvention
+is effected by exercising rights under this License with respect to
+the covered work, and you disclaim any intention to limit operation or
+modification of the work as a means of enforcing, against the work's
+users, your or third parties' legal rights to forbid circumvention of
+technological measures.
+
+ 4. Conveying Verbatim Copies.
+
+ You may convey 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;
+keep intact all notices stating that this License and any
+non-permissive terms added in accord with section 7 apply to the code;
+keep intact all notices of the absence of any warranty; and give all
+recipients a copy of this License along with the Program.
+
+ You may charge any price or no price for each copy that you convey,
+and you may offer support or warranty protection for a fee.
+
+ 5. Conveying Modified Source Versions.
+
+ You may convey a work based on the Program, or the modifications to
+produce it from the Program, in the form of source code under the
+terms of section 4, provided that you also meet all of these conditions:
+
+ a) The work must carry prominent notices stating that you modified
+ it, and giving a relevant date.
+
+ b) The work must carry prominent notices stating that it is
+ released under this License and any conditions added under section
+ 7. This requirement modifies the requirement in section 4 to
+ "keep intact all notices".
+
+ c) You must license the entire work, as a whole, under this
+ License to anyone who comes into possession of a copy. This
+ License will therefore apply, along with any applicable section 7
+ additional terms, to the whole of the work, and all its parts,
+ regardless of how they are packaged. This License gives no
+ permission to license the work in any other way, but it does not
+ invalidate such permission if you have separately received it.
+
+ d) If the work has interactive user interfaces, each must display
+ Appropriate Legal Notices; however, if the Program has interactive
+ interfaces that do not display Appropriate Legal Notices, your
+ work need not make them do so.
+
+ A compilation of a covered work with other separate and independent
+works, which are not by their nature extensions of the covered work,
+and which are not combined with it such as to form a larger program,
+in or on a volume of a storage or distribution medium, is called an
+"aggregate" if the compilation and its resulting copyright are not
+used to limit the access or legal rights of the compilation's users
+beyond what the individual works permit. Inclusion of a covered work
+in an aggregate does not cause this License to apply to the other
+parts of the aggregate.
+
+ 6. Conveying Non-Source Forms.
+
+ You may convey a covered work in object code form under the terms
+of sections 4 and 5, provided that you also convey the
+machine-readable Corresponding Source under the terms of this License,
+in one of these ways:
+
+ a) Convey the object code in, or embodied in, a physical product
+ (including a physical distribution medium), accompanied by the
+ Corresponding Source fixed on a durable physical medium
+ customarily used for software interchange.
+
+ b) Convey the object code in, or embodied in, a physical product
+ (including a physical distribution medium), accompanied by a
+ written offer, valid for at least three years and valid for as
+ long as you offer spare parts or customer support for that product
+ model, to give anyone who possesses the object code either (1) a
+ copy of the Corresponding Source for all the software in the
+ product that is covered by this License, on a durable physical
+ medium customarily used for software interchange, for a price no
+ more than your reasonable cost of physically performing this
+ conveying of source, or (2) access to copy the
+ Corresponding Source from a network server at no charge.
+
+ c) Convey individual copies of the object code with a copy of the
+ written offer to provide the Corresponding Source. This
+ alternative is allowed only occasionally and noncommercially, and
+ only if you received the object code with such an offer, in accord
+ with subsection 6b.
+
+ d) Convey the object code by offering access from a designated
+ place (gratis or for a charge), and offer equivalent access to the
+ Corresponding Source in the same way through the same place at no
+ further charge. You need not require recipients to copy the
+ Corresponding Source along with the object code. If the place to
+ copy the object code is a network server, the Corresponding Source
+ may be on a different server (operated by you or a third party)
+ that supports equivalent copying facilities, provided you maintain
+ clear directions next to the object code saying where to find the
+ Corresponding Source. Regardless of what server hosts the
+ Corresponding Source, you remain obligated to ensure that it is
+ available for as long as needed to satisfy these requirements.
+
+ e) Convey the object code using peer-to-peer transmission, provided
+ you inform other peers where the object code and Corresponding
+ Source of the work are being offered to the general public at no
+ charge under subsection 6d.
+
+ A separable portion of the object code, whose source code is excluded
+from the Corresponding Source as a System Library, need not be
+included in conveying the object code work.
+
+ A "User Product" is either (1) a "consumer product", which means any
+tangible personal property which is normally used for personal, family,
+or household purposes, or (2) anything designed or sold for incorporation
+into a dwelling. In determining whether a product is a consumer product,
+doubtful cases shall be resolved in favor of coverage. For a particular
+product received by a particular user, "normally used" refers to a
+typical or common use of that class of product, regardless of the status
+of the particular user or of the way in which the particular user
+actually uses, or expects or is expected to use, the product. A product
+is a consumer product regardless of whether the product has substantial
+commercial, industrial or non-consumer uses, unless such uses represent
+the only significant mode of use of the product.
+
+ "Installation Information" for a User Product means any methods,
+procedures, authorization keys, or other information required to install
+and execute modified versions of a covered work in that User Product from
+a modified version of its Corresponding Source. The information must
+suffice to ensure that the continued functioning of the modified object
+code is in no case prevented or interfered with solely because
+modification has been made.
+
+ If you convey an object code work under this section in, or with, or
+specifically for use in, a User Product, and the conveying occurs as
+part of a transaction in which the right of possession and use of the
+User Product is transferred to the recipient in perpetuity or for a
+fixed term (regardless of how the transaction is characterized), the
+Corresponding Source conveyed under this section must be accompanied
+by the Installation Information. But this requirement does not apply
+if neither you nor any third party retains the ability to install
+modified object code on the User Product (for example, the work has
+been installed in ROM).
+
+ The requirement to provide Installation Information does not include a
+requirement to continue to provide support service, warranty, or updates
+for a work that has been modified or installed by the recipient, or for
+the User Product in which it has been modified or installed. Access to a
+network may be denied when the modification itself materially and
+adversely affects the operation of the network or violates the rules and
+protocols for communication across the network.
+
+ Corresponding Source conveyed, and Installation Information provided,
+in accord with this section must be in a format that is publicly
+documented (and with an implementation available to the public in
+source code form), and must require no special password or key for
+unpacking, reading or copying.
+
+ 7. Additional Terms.
+
+ "Additional permissions" are terms that supplement the terms of this
+License by making exceptions from one or more of its conditions.
+Additional permissions that are applicable to the entire Program shall
+be treated as though they were included in this License, to the extent
+that they are valid under applicable law. If additional permissions
+apply only to part of the Program, that part may be used separately
+under those permissions, but the entire Program remains governed by
+this License without regard to the additional permissions.
+
+ When you convey a copy of a covered work, you may at your option
+remove any additional permissions from that copy, or from any part of
+it. (Additional permissions may be written to require their own
+removal in certain cases when you modify the work.) You may place
+additional permissions on material, added by you to a covered work,
+for which you have or can give appropriate copyright permission.
+
+ Notwithstanding any other provision of this License, for material you
+add to a covered work, you may (if authorized by the copyright holders of
+that material) supplement the terms of this License with terms:
+
+ a) Disclaiming warranty or limiting liability differently from the
+ terms of sections 15 and 16 of this License; or
+
+ b) Requiring preservation of specified reasonable legal notices or
+ author attributions in that material or in the Appropriate Legal
+ Notices displayed by works containing it; or
+
+ c) Prohibiting misrepresentation of the origin of that material, or
+ requiring that modified versions of such material be marked in
+ reasonable ways as different from the original version; or
+
+ d) Limiting the use for publicity purposes of names of licensors or
+ authors of the material; or
+
+ e) Declining to grant rights under trademark law for use of some
+ trade names, trademarks, or service marks; or
+
+ f) Requiring indemnification of licensors and authors of that
+ material by anyone who conveys the material (or modified versions of
+ it) with contractual assumptions of liability to the recipient, for
+ any liability that these contractual assumptions directly impose on
+ those licensors and authors.
+
+ All other non-permissive additional terms are considered "further
+restrictions" within the meaning of section 10. If the Program as you
+received it, or any part of it, contains a notice stating that it is
+governed by this License along with a term that is a further
+restriction, you may remove that term. If a license document contains
+a further restriction but permits relicensing or conveying under this
+License, you may add to a covered work material governed by the terms
+of that license document, provided that the further restriction does
+not survive such relicensing or conveying.
+
+ If you add terms to a covered work in accord with this section, you
+must place, in the relevant source files, a statement of the
+additional terms that apply to those files, or a notice indicating
+where to find the applicable terms.
+
+ Additional terms, permissive or non-permissive, may be stated in the
+form of a separately written license, or stated as exceptions;
+the above requirements apply either way.
+
+ 8. Termination.
+
+ You may not propagate or modify a covered work except as expressly
+provided under this License. Any attempt otherwise to propagate or
+modify it is void, and will automatically terminate your rights under
+this License (including any patent licenses granted under the third
+paragraph of section 11).
+
+ However, if you cease all violation of this License, then your
+license from a particular copyright holder is reinstated (a)
+provisionally, unless and until the copyright holder explicitly and
+finally terminates your license, and (b) permanently, if the copyright
+holder fails to notify you of the violation by some reasonable means
+prior to 60 days after the cessation.
+
+ Moreover, your license from a particular copyright holder is
+reinstated permanently if the copyright holder notifies you of the
+violation by some reasonable means, this is the first time you have
+received notice of violation of this License (for any work) from that
+copyright holder, and you cure the violation prior to 30 days after
+your receipt of the notice.
+
+ Termination of your rights under this section does not terminate the
+licenses of parties who have received copies or rights from you under
+this License. If your rights have been terminated and not permanently
+reinstated, you do not qualify to receive new licenses for the same
+material under section 10.
+
+ 9. Acceptance Not Required for Having Copies.
+
+ You are not required to accept this License in order to receive or
+run a copy of the Program. Ancillary propagation of a covered work
+occurring solely as a consequence of using peer-to-peer transmission
+to receive a copy likewise does not require acceptance. However,
+nothing other than this License grants you permission to propagate or
+modify any covered work. These actions infringe copyright if you do
+not accept this License. Therefore, by modifying or propagating a
+covered work, you indicate your acceptance of this License to do so.
+
+ 10. Automatic Licensing of Downstream Recipients.
+
+ Each time you convey a covered work, the recipient automatically
+receives a license from the original licensors, to run, modify and
+propagate that work, subject to this License. You are not responsible
+for enforcing compliance by third parties with this License.
+
+ An "entity transaction" is a transaction transferring control of an
+organization, or substantially all assets of one, or subdividing an
+organization, or merging organizations. If propagation of a covered
+work results from an entity transaction, each party to that
+transaction who receives a copy of the work also receives whatever
+licenses to the work the party's predecessor in interest had or could
+give under the previous paragraph, plus a right to possession of the
+Corresponding Source of the work from the predecessor in interest, if
+the predecessor has it or can get it with reasonable efforts.
+
+ You may not impose any further restrictions on the exercise of the
+rights granted or affirmed under this License. For example, you may
+not impose a license fee, royalty, or other charge for exercise of
+rights granted under this License, and you may not initiate litigation
+(including a cross-claim or counterclaim in a lawsuit) alleging that
+any patent claim is infringed by making, using, selling, offering for
+sale, or importing the Program or any portion of it.
+
+ 11. Patents.
+
+ A "contributor" is a copyright holder who authorizes use under this
+License of the Program or a work on which the Program is based. The
+work thus licensed is called the contributor's "contributor version".
+
+ A contributor's "essential patent claims" are all patent claims
+owned or controlled by the contributor, whether already acquired or
+hereafter acquired, that would be infringed by some manner, permitted
+by this License, of making, using, or selling its contributor version,
+but do not include claims that would be infringed only as a
+consequence of further modification of the contributor version. For
+purposes of this definition, "control" includes the right to grant
+patent sublicenses in a manner consistent with the requirements of
+this License.
+
+ Each contributor grants you a non-exclusive, worldwide, royalty-free
+patent license under the contributor's essential patent claims, to
+make, use, sell, offer for sale, import and otherwise run, modify and
+propagate the contents of its contributor version.
+
+ In the following three paragraphs, a "patent license" is any express
+agreement or commitment, however denominated, not to enforce a patent
+(such as an express permission to practice a patent or covenant not to
+sue for patent infringement). To "grant" such a patent license to a
+party means to make such an agreement or commitment not to enforce a
+patent against the party.
+
+ If you convey a covered work, knowingly relying on a patent license,
+and the Corresponding Source of the work is not available for anyone
+to copy, free of charge and under the terms of this License, through a
+publicly available network server or other readily accessible means,
+then you must either (1) cause the Corresponding Source to be so
+available, or (2) arrange to deprive yourself of the benefit of the
+patent license for this particular work, or (3) arrange, in a manner
+consistent with the requirements of this License, to extend the patent
+license to downstream recipients. "Knowingly relying" means you have
+actual knowledge that, but for the patent license, your conveying the
+covered work in a country, or your recipient's use of the covered work
+in a country, would infringe one or more identifiable patents in that
+country that you have reason to believe are valid.
+
+ If, pursuant to or in connection with a single transaction or
+arrangement, you convey, or propagate by procuring conveyance of, a
+covered work, and grant a patent license to some of the parties
+receiving the covered work authorizing them to use, propagate, modify
+or convey a specific copy of the covered work, then the patent license
+you grant is automatically extended to all recipients of the covered
+work and works based on it.
+
+ A patent license is "discriminatory" if it does not include within
+the scope of its coverage, prohibits the exercise of, or is
+conditioned on the non-exercise of one or more of the rights that are
+specifically granted under this License. You may not convey a covered
+work if you are a party to an arrangement with a third party that is
+in the business of distributing software, under which you make payment
+to the third party based on the extent of your activity of conveying
+the work, and under which the third party grants, to any of the
+parties who would receive the covered work from you, a discriminatory
+patent license (a) in connection with copies of the covered work
+conveyed by you (or copies made from those copies), or (b) primarily
+for and in connection with specific products or compilations that
+contain the covered work, unless you entered into that arrangement,
+or that patent license was granted, prior to 28 March 2007.
+
+ Nothing in this License shall be construed as excluding or limiting
+any implied license or other defenses to infringement that may
+otherwise be available to you under applicable patent law.
+
+ 12. No Surrender of Others' Freedom.
+
+ If 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 convey a
+covered work so as to satisfy simultaneously your obligations under this
+License and any other pertinent obligations, then as a consequence you may
+not convey it at all. For example, if you agree to terms that obligate you
+to collect a royalty for further conveying from those to whom you convey
+the Program, the only way you could satisfy both those terms and this
+License would be to refrain entirely from conveying the Program.
+
+ 13. Use with the GNU Affero General Public License.
+
+ Notwithstanding any other provision of this License, you have
+permission to link or combine any covered work with a work licensed
+under version 3 of the GNU Affero General Public License into a single
+combined work, and to convey the resulting work. The terms of this
+License will continue to apply to the part which is the covered work,
+but the special requirements of the GNU Affero General Public License,
+section 13, concerning interaction through a network will apply to the
+combination as such.
+
+ 14. Revised Versions of this License.
+
+ The Free Software Foundation may publish revised and/or new versions of
+the GNU 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 that a certain numbered version of the GNU General
+Public License "or any later version" applies to it, you have the
+option of following the terms and conditions either of that numbered
+version or of any later version published by the Free Software
+Foundation. If the Program does not specify a version number of the
+GNU General Public License, you may choose any version ever published
+by the Free Software Foundation.
+
+ If the Program specifies that a proxy can decide which future
+versions of the GNU General Public License can be used, that proxy's
+public statement of acceptance of a version permanently authorizes you
+to choose that version for the Program.
+
+ Later license versions may give you additional or different
+permissions. However, no additional obligations are imposed on any
+author or copyright holder as a result of your choosing to follow a
+later version.
+
+ 15. Disclaimer of Warranty.
+
+ 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.
+
+ 16. Limitation of Liability.
+
+ IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
+WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MODIFIES AND/OR CONVEYS
+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.
+
+ 17. Interpretation of Sections 15 and 16.
+
+ If the disclaimer of warranty and limitation of liability provided
+above cannot be given local legal effect according to their terms,
+reviewing courts shall apply local law that most closely approximates
+an absolute waiver of all civil liability in connection with the
+Program, unless a warranty or assumption of liability accompanies a
+copy of the Program in return for a fee.
+
+ 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
+state 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 3 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, see <http://www.gnu.org/licenses/>.
+
+Also add information on how to contact you by electronic and paper mail.
+
+ If the program does terminal interaction, make it output a short
+notice like this when it starts in an interactive mode:
+
+ <program> Copyright (C) <year> <name of author>
+ This program 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, your program's commands
+might be different; for a GUI interface, you would use an "about box".
+
+ You should also get your employer (if you work as a programmer) or school,
+if any, to sign a "copyright disclaimer" for the program, if necessary.
+For more information on this, and how to apply and follow the GNU GPL, see
+<http://www.gnu.org/licenses/>.
+
+ The GNU 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. But first, please read
+<http://www.gnu.org/philosophy/why-not-lgpl.html>.
