#  The licenses for most software are designed to take away your\n\

#General Public License applies to most of the Free Software\n\

#  When we speak of free software, we are referring to freedom, not\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\

#\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\

#  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\
#	Appendix: 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) 19yy  <name of author>\n\
#\n\
#    This program is free software; you can redistribute it and/or modify\n\
#    it under the terms of the GNU General Public License as published by\n\
#    the Free Software Foundation; either version 2 of the License, or\n\
#    (at your option) any later version.\n\
#\n\
#    This program is distributed in the hope that it will be useful,\n\
#    but WITHOUT ANY WARRANTY; without even the implied warranty of\n\
#    MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.  See the\n\
#    GNU General Public License for more details.\n\
#\n\
#    You should have received a copy of the GNU General Public License\n\
#    along with this program; if not, write to the Free Software\n\
#    Foundation, Inc., 675 Mass Ave, Cambridge, MA 02139, USA.\n\
#\n\
#Also add information on how to contact you by electronic and paper mail.\n\
#\n\
#If the program is interactive, make it output a short notice like this\n\
#when it starts in an interactive mode:\n\
#\n\
#    Gnomovision version 69, Copyright (C) 19yy name of author\n\
#    Gnomovision comes with ABSOLUTELY NO WARRANTY; for details type `show w'.\n\
#    This is free software, and you are welcome to redistribute it\n\
#    under certain conditions; type `show c' for details.\n\
#\n\
#The hypothetical commands `show w' and `show c' should show the appropriate\n\
#parts of the General Public License.  Of course, the commands you use may\n\
#be called something other than `show w' and `show c'; they could even be\n\
#mouse-clicks or menu items--whatever suits your program.\n\
#\n\
#You should also get your employer (if you work as a programmer) or your\n\
#school, if any, to sign a \"copyright disclaimer\" for the program, if\n\
#necessary.  Here is a sample; alter the names:\n\
#\n\
#  Yoyodyne, Inc., hereby disclaims all copyright interest in the program\n\

#This General Public License does not permit incorporating your program into\n\
#proprietary programs.  If your program is a subroutine library, you may\n\
#consider it more useful to permit linking proprietary applications with the\n\
#library.  If this is what you want to do, use the GNU Library General\n\
#Public License instead of this License.\n\
