"\n"
"  Copyright (C) 1989, 1991 Free Software Foundation, Inc.\n"
"      51 Franklin Street, Fifth Floor, Boston, MA  02110-1301, USA\n"
"  Everyone is permitted to copy and distribute verbatim copies\n"
"  of this license document, but changing it is not allowed.\n"
"\n"
" 			    Preamble\n"
"\n"
"   The licenses for most software are designed to take away your\n"
" freedom to share and change it.  By contrast, the GNU General Public\n"
" License is intended to guarantee your freedom to share and change free\n"
" software--to make sure the software is free for all its users.  This\n"

  " General Public License applies to most of the Free Software\n"
" Foundation's software and to any other program whose authors commit to\n"
" using it.  (Some other Free Software Foundation software is covered by\n"
" the GNU Library General Public License instead.)  You can apply it to\n"
" your programs, too.\n"
"\n"
"   When we speak of free software, we are referring to freedom, not\n"
" price.  Our General Public Licenses are designed to make sure that you\n"
" have the freedom to distribute copies of free software (and charge for\n"
" this service if you wish), that you receive source code or can get it\n"
" if you want it, that you can change the software or use pieces of it\n"

  " in new free programs; and that you know you can do these things.\n"
"\n"
"   To protect your rights, we need to make restrictions that forbid\n"
" anyone to deny you these rights or to ask you to surrender the rights.\n"
" These restrictions translate to certain responsibilities for you if you\n"
" distribute copies of the software, or if you modify it.\n"
"\n"
"   For example, if you distribute copies of such a program, whether\n"
" gratis or for a fee, you must give the recipients all the rights that\n"
" you have.  You must make sure that they, too, receive or can get the\n"
" source code.  And you must show them these terms so they know their\n"
" rights.\n"
"\n"

  "   We protect your rights with two steps: (1) copyright the software, and\n"
" (2) offer you this license which gives you legal permission to copy,\n"
" distribute and/or modify the software.\n"
"\n"
"   Also, for each author's protection and ours, we want to make certain\n"
" that everyone understands that there is no warranty for this free\n"
" software.  If the software is modified by someone else and passed on, we\n"
" want its recipients to know that what they have is not the original, so\n"
" that any problems introduced by others will not reflect on the original\n"
" authors' reputations.\n"
" \n"
"   Finally, any free program is threatened constantly by software\n"

  " patents.  We wish to avoid the danger that redistributors of a free\n"
" program will individually obtain patent licenses, in effect making the\n"
" program proprietary.  To prevent this, we have made it clear that any\n"
" patent must be licensed for everyone's free use or not licensed at all.\n"
"\n"
"   The precise terms and conditions for copying, distribution and\n"
" modification follow.\n"
"\n"
" 		    GNU GENERAL PUBLIC LICENSE\n"
"    TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION\n"
"\n"
"   0. This License applies to any program or other work which contains\n"
" a notice placed by the copyright holder saying it may be distributed\n"

  " under the terms of this General Public License.  The \"Program\", below,\n"
" refers to any such program or work, and a \"work based on the Program\"\n"
" means either the Program or any derivative work under copyright law:\n"
" that is to say, a work containing the Program or a portion of it,\n"
" either verbatim or with modifications and/or translated into another\n"
" language.  (Hereinafter, translation is included without limitation in\n"
" the term \"modification\".)  Each licensee is addressed as \"you\".\n"
"\n"
" Activities other than copying, distribution and modification are not\n"
" covered by this License; they are outside its scope.  The act of\n"

  " running the Program is not restricted, and the output from the Program\n"
" is covered only if its contents constitute a work based on the\n"
" Program (independent of having been made by running the Program).\n"
" Whether that is true depends on what the Program does.\n"
"\n"
"   1. You may copy and distribute verbatim copies of the Program's\n"
" source code as you receive it, in any medium, provided that you\n"
" conspicuously and appropriately publish on each copy an appropriate\n"
" copyright notice and disclaimer of warranty; keep intact all the\n"
" notices that refer to this License and to the absence of any warranty;\n"

  " and give any other recipients of the Program a copy of this License\n"
" along with the Program.\n"
"\n"
" You may charge a fee for the physical act of transferring a copy, and\n"
" you may at your option offer warranty protection in exchange for a fee.\n"
"\n"
"   2. You may modify your copy or copies of the Program or any portion\n"
" of it, thus forming a work based on the Program, and copy and\n"
" distribute such modifications or work under the terms of Section 1\n"
" above, provided that you also meet all of these conditions:\n"
"\n"
"     a) You must cause the modified files to carry prominent notices\n"
"     stating that you changed the files and the date of any change.\n"
"\n"

  "     b) You must cause any work that you distribute or publish, that in\n"
"     whole or in part contains or is derived from the Program or any\n"
"     part thereof, to be licensed as a whole at no charge to all third\n"
"     parties under the terms of this License.\n"
"\n"
"     c) If the modified program normally reads commands interactively\n"
"     when run, you must cause it, when started running for such\n"
"     interactive use in the most ordinary way, to print or display an\n"
"     announcement including an appropriate copyright notice and a\n"
"     notice that there is no warranty (or else, saying that you provide\n"

  "     a warranty) and that users may redistribute the program under\n"
"     these conditions, and telling the user how to view a copy of this\n"
"     License.  (Exception: if the Program itself is interactive but\n"
"     does not normally print such an announcement, your work based on\n"
"     the Program is not required to print an announcement.)\n"
"\n"
" These requirements apply to the modified work as a whole.  If\n"
" identifiable sections of that work are not derived from the Program,\n"
" and can be reasonably considered independent and separate works in\n"
" themselves, then this License, and its terms, do not apply to those\n"

  " sections when you distribute them as separate works.  But when you\n"
" distribute the same sections as part of a whole which is a work based\n"
" on the Program, the distribution of the whole must be on the terms of\n"
" this License, whose permissions for other licensees extend to the\n"
" entire whole, and thus to each and every part regardless of who wrote it.\n"
"\n"
" Thus, it is not the intent of this section to claim rights or contest\n"
" your rights to work written entirely by you; rather, the intent is to\n"
" exercise the right to control the distribution of derivative or\n"
" collective works based on the Program.\n"
"\n"

  " In addition, mere aggregation of another work not based on the Program\n"
" with the Program (or with a work based on the Program) on a volume of\n"
" a storage or distribution medium does not bring the other work under\n"
" the scope of this License.\n"
"\n"
"   3. You may copy and distribute the Program (or a work based on it,\n"
" under Section 2) in object code or executable form under the terms of\n"
" Sections 1 and 2 above provided that you also do one of the following:\n"
"\n"
"     a) Accompany it with the complete corresponding machine-readable\n"
"     source code, which must be distributed under the terms of Sections\n"

  "     1 and 2 above on a medium customarily used for software interchange; or,\n"
"\n"
"     b) Accompany it with a written offer, valid for at least three\n"
"     years, to give any third party, for a charge no more than your\n"
"     cost of physically performing source distribution, a complete\n"
"     machine-readable copy of the corresponding source code, to be\n"
"     distributed under the terms of Sections 1 and 2 above on a medium\n"
"     customarily used for software interchange; or,\n"
"\n"
"     c) Accompany it with the information you received as to the offer\n"
"     to distribute corresponding source code.  (This alternative is\n"

  "     allowed only for noncommercial distribution and only if you\n"
"     received the program in object code or executable form with such\n"
"     an offer, in accord with Subsection b above.)\n"
"\n"
" The source code for a work means the preferred form of the work for\n"
" making modifications to it.  For an executable work, complete source\n"
" code means all the source code for all modules it contains, plus any\n"
" associated interface definition files, plus the scripts used to\n"
" control compilation and installation of the executable.  However, as a\n"
" special exception, the source code distributed need not include\n"

  " anything that is normally distributed (in either source or binary\n"
" form) with the major components (compiler, kernel, and so on) of the\n"
" operating system on which the executable runs, unless that component\n"
" itself accompanies the executable.\n"
"\n"
" If distribution of executable or object code is made by offering\n"
" access to copy from a designated place, then offering equivalent\n"
" access to copy the source code from the same place counts as\n"
" distribution of the source code, even though third parties are not\n"
" compelled to copy the source along with the object code.\n"
" \n"
"   4. You may not copy, modify, sublicense, or distribute the Program\n"

  " except as expressly provided under this License.  Any attempt\n"
" otherwise to copy, modify, sublicense or distribute the Program is\n"
" void, and will automatically terminate your rights under this License.\n"
" However, parties who have received copies, or rights, from you under\n"
" this License will not have their licenses terminated so long as such\n"
" parties remain in full compliance.\n"
"\n"
"   5. You are not required to accept this License, since you have not\n"
" signed it.  However, nothing else grants you permission to modify or\n"
" distribute the Program or its derivative works.  These actions are\n"
" prohibited by law if you do not accept this License.  Therefore, by\n"

  " modifying or distributing the Program (or any work based on the\n"
" Program), you indicate your acceptance of this License to do so, and\n"
" all its terms and conditions for copying, distributing or modifying\n"
" the Program or works based on it.\n"
"\n"
"   6. Each time you redistribute the Program (or any work based on the\n"
" Program), the recipient automatically receives a license from the\n"
" original licensor to copy, distribute or modify the Program subject to\n"
" these terms and conditions.  You may not impose any further\n"
" restrictions on the recipients' exercise of the rights granted herein.\n"
" You are not responsible for enforcing compliance by third parties to\n"

  " this License.\n"
" \n"
"   7. If, as a consequence of a court judgment or allegation of patent\n"
" infringement or for any other reason (not limited to patent issues),\n"
" conditions are imposed on you (whether by court order, agreement or\n"
" otherwise) that contradict the conditions of this License, they do not\n"
" excuse you from the conditions of this License.  If you cannot\n"
" distribute so as to satisfy simultaneously your obligations under this\n"
" License and any other pertinent obligations, then as a consequence you\n"
" may not distribute the Program at all.  For example, if a patent\n"
" license would not permit royalty-free redistribution of the Program by\n"

  " all those who receive copies directly or indirectly through you, then\n"
" the only way you could satisfy both it and this License would be to\n"
" refrain entirely from distribution of the Program.\n"
"\n"
" If any portion of this section is held invalid or unenforceable under\n"
" any particular circumstance, the balance of the section is intended to\n"
" apply and the section as a whole is intended to apply in other\n"
" circumstances.\n"
"\n"
" It is not the purpose of this section to induce you to infringe any\n"
" patents or other property right claims or to contest validity of any\n"
" such claims; this section has the sole purpose of protecting the\n"

  " integrity of the free software distribution system, which is\n"
" implemented by public license practices.  Many people have made\n"
" generous contributions to the wide range of software distributed\n"
" through that system in reliance on consistent application of that\n"
" system; it is up to the author/donor to decide if he or she is willing\n"
" to distribute software through any other system and a licensee cannot\n"
" impose that choice.\n"
"\n"
" This section is intended to make thoroughly clear what is believed to\n"
" be a consequence of the rest of this License.\n"
"\n"
"   8. If the distribution and/or use of the Program is restricted in\n"

  " certain countries either by patents or by copyrighted interfaces, the\n"
" original copyright holder who places the Program under this License\n"
" may add an explicit geographical distribution limitation excluding\n"
" those countries, so that distribution is permitted only in or among\n"
" countries not thus excluded.  In such case, this License incorporates\n"
" the limitation as if written in the body of this License.\n"
"\n"
"   9. The Free Software Foundation may publish revised and/or new versions\n"
" of the General Public License from time to time.  Such new versions will\n"
" be similar in spirit to the present version, but may differ in detail to\n"

  " address new problems or concerns.\n"
" \n"
" Each version is given a distinguishing version number.  If the Program\n"
" specifies a version number of this License which applies to it and \"any\n"
" later version\", you have the option of following the terms and conditions\n"
" either of that version or of any later version published by the Free\n"
" Software Foundation.  If the Program does not specify a version number of\n"
" this License, you may choose any version ever published by the Free Software\n"
" Foundation.\n"
"\n"
"   10. If you wish to incorporate parts of the Program into other free\n"
" programs whose distribution conditions are different, write to the author\n"
" to ask for permission.  For software which is copyrighted by the Free\n"
" Software Foundation, write to the Free Software Foundation; we sometimes\n"
" make exceptions for this.  Our decision will be guided by the two goals\n"
" of preserving the free status of all derivatives of our free software and\n"
" of promoting the sharing and reuse of software generally.\n"
"\n"
" 			    NO WARRANTY\n"
"\n"
"   11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY\n"
" FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW.  EXCEPT WHEN\n"
" OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES\n"

  " PROVIDE THE PROGRAM \"AS IS\" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED\n"
" OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF\n"
" MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE.  THE ENTIRE RISK AS\n"
" TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU.  SHOULD THE\n"
" PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING,\n"
" REPAIR OR CORRECTION.\n"
"\n"
"   12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING\n"
" WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR\n"
" REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES,\n"

  " INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING\n"
" OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED\n"
" TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY\n"
" YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER\n"
" PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE\n"
" POSSIBILITY OF SUCH DAMAGES.\n"
"\n"
" 		     END OF TERMS AND CONDITIONS\n"
"\n"
" 	    How to Apply These Terms to Your New Programs\n"
"\n"
"   If you develop a new program, and you want it to be of the greatest\n"
" possible use to the public, the best way to achieve this is to make it\n"
" free software which everyone can redistribute and change under these terms.\n"
"\n"
"   To do so, attach the following notices to the program.  It is safest\n"
" to attach them to the start of each source file to most effectively\n"
" convey the exclusion of warranty; and each file should have at least\n"
" the \"copyright\" line and a pointer to where the full notice is found.\n"
"\n"
"     <one line to give the program's name and a brief idea of what it does.>\n"
"     Copyright (C) <year>  <name of author>\n"
"\n"

"\n"
"\n"
" Also add information on how to contact you by electronic and paper mail.\n"
" \n"
