By contrast, the GNU General Public+License is intended to guarantee your freedom to share and change free+software--to make sure the software is free for all its users.  This+General Public License applies to most of the Free Software+Foundation's software and to any other program whose authors commit to+using it.  (Some other Free Software Foundation software is covered by+the GNU Lesser General Public License instead.)  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+this service 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 make restrictions that forbid+anyone to deny you these rights or to ask you to surrender the rights.+These restrictions translate to certain responsibilities for you if you+distribute copies of the software, or if you modify it.++  For example, if you distribute copies of such a program, whether+gratis or for a fee, you must give the recipients all the rights that+you have.  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.++  We protect your rights with two steps: (1) copyright the software, and+(2) offer you this license which gives you legal permission to copy,+distribute and/or modify the software.++  Also, for each author's protection and ours, we want to make certain+that everyone understands that there is no warranty for this free+software.  If the software is modified by someone else and passed on, we+want its recipients to know that what they have is not the original, so+that any problems introduced by others will not reflect on the original+authors' reputations.++  Finally, any free program is threatened constantly by software+patents.  We wish to avoid the danger that redistributors of a free+program will individually obtain patent licenses, in effect making the+program proprietary.  To prevent this, we have made it clear that any+patent must be licensed for everyone's free use or not licensed at all.++  The precise terms and conditions for copying, distribution and+modification follow.++             GNU GENERAL PUBLIC LICENSE+   TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION++  0. This License applies to any program or other work which contains+a notice placed by the copyright holder saying it may be distributed+under the terms of this General Public License.  The "Program", below,+refers to any such program or work, and a "work based on the Program"+means either the Program or any derivative work under copyright law:+that is to say, a work containing the Program or a portion of it,+either verbatim or with modifications and/or translated into another+language.  (Hereinafter, translation is included without limitation in+the term "modification".)  Each licensee is addressed as "you".++Activities other than copying, distribution and modification are not+covered by this License; they are outside its scope.  The act of+running the Program is not restricted, and the output from the Program+is covered only if its contents constitute a work based on the+Program (independent of having been made by running the Program).+Whether that is true depends on what the Program does.++  1. You may copy and distribute 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 and disclaimer of warranty; keep intact all the+notices that refer to this License and to the absence of any warranty;+and give any other recipients of the Program a copy of this License+along with the Program.++You may charge a fee for the physical act of transferring a copy, and+you may at your option offer warranty protection in exchange for a fee.++  2. You may modify your copy or copies of the Program or any portion+of it, thus forming a work based on the Program, and copy and+distribute such modifications or work under the terms of Section 1+above, provided that you also meet all of these conditions:++    a) You must cause the modified files to carry prominent notices+    stating that you changed the files and the date of any change.++    b) You must cause any work that you distribute or publish, that in+    whole or in part contains or is derived from the Program or any+    part thereof, to be licensed as a whole at no charge to all third+    parties under the terms of this License.++    c) If the modified program normally reads commands interactively+    when run, you must cause it, when started running for such+    interactive use in the most ordinary way, to print or display an+    announcement including an appropriate copyright notice and a+    notice that there is no warranty (or else, saying that you provide+    a warranty) and that users may redistribute the program under+    these conditions, and telling the user how to view a copy of this+    License.  (Exception: if the Program itself is interactive but+    does not normally print such an announcement, your work based on+    the Program is not required to print an announcement.)++These requirements apply to the modified work as a whole.  If+identifiable sections of that work are not derived from the Program,+and can be reasonably considered independent and separate works in+themselves, then this License, and its terms, do not apply to those+sections when you distribute them as separate works.  But when you+distribute the same sections as part of a whole which is a work based+on the Program, the distribution of the whole must be on the terms of+this License, whose permissions for other licensees extend to the+entire whole, and thus to each and every part regardless of who wrote it.++Thus, it is not the intent of this section to claim rights or contest+your rights to work written entirely by you; rather, the intent is to+exercise the right to control the distribution of derivative or+collective works based on the Program.++In addition, mere aggregation of another work not based on the Program+with the Program (or with a work based on the Program) on a volume of+a storage or distribution medium does not bring the other work under+the scope of this License.++  3. You may copy and distribute the Program (or a work based on it,+under Section 2) in object code or executable form under the terms of+Sections 1 and 2 above provided that you also do one of the following:++    a) Accompany it with the complete corresponding machine-readable+    source code, which must be distributed under the terms of Sections+    1 and 2 above on a medium customarily used for software interchange; or,++    b) Accompany it with a written offer, valid for at least three+    years, to give any third party, for a charge no more than your+    cost of physically performing source distribution, a complete+    machine-readable copy of the corresponding source code, to be+    distributed under the terms of Sections 1 and 2 above on a medium+    customarily used for software interchange; or,++    c) Accompany it with the information you received as to the offer+    to distribute corresponding source code.  (This alternative is+    allowed only for noncommercial distribution and only if you+    received the program in object code or executable form with such+    an offer, in accord with Subsection b above.)++The source code for a work means the preferred form of the work for+making modifications to it.  For an executable work, complete source+code means all the source code for all modules it contains, plus any+associated interface definition files, plus the scripts used to+control compilation and installation of the executable.  However, as a+special exception, the source code distributed need not include+anything that is normally distributed (in either source or binary+form) with the major components (compiler, kernel, and so on) of the+operating system on which the executable runs, unless that component+itself accompanies the executable.++If distribution of executable or object code is made by offering+access to copy from a designated place, then offering equivalent+access to copy the source code from the same place counts as+distribution of the source code, even though third parties are not+compelled to copy the source along with the object code.++  4. You may not copy, modify, sublicense, or distribute the Program+except as expressly provided under this License.  Any attempt+otherwise to copy, modify, sublicense or distribute the Program is+void, and will automatically terminate your rights under this License.+However, parties who have received copies, or rights, from you under+this License will not have their licenses terminated so long as such+parties remain in full compliance.++  5. You are not required to accept this License, since you have not+signed it.  However, nothing else grants you permission to modify or+distribute the Program or its derivative works.  These actions are+prohibited by law if you do not accept this License.  Therefore, by+modifying or distributing the Program (or any work based on the+Program), you indicate your acceptance of this License to do so, and+all its terms and conditions for copying, distributing or modifying+the Program or works based on it.++  6. Each time you redistribute the Program (or any work based on the+Program), the recipient automatically receives a license from the+original licensor to copy, distribute or modify the Program subject to+these terms and conditions.  You may not impose any further+restrictions on the recipients' exercise of the rights granted herein.+You are not responsible for enforcing compliance by third parties to+this License.++  7. If, as a consequence of a court judgment or allegation of patent+infringement or for any other reason (not limited to patent issues),+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+distribute so as to satisfy simultaneously your obligations under this+License and any other pertinent obligations, then as a consequence you+may not distribute the Program at all.  For example, if a patent+license would not permit royalty-free redistribution of the Program by+all those who receive copies directly or indirectly through you, then+the only way you could satisfy both it and this License would be to+refrain entirely from distribution of the Program.++If any portion of this section is held invalid or unenforceable under+any particular circumstance, the balance of the section is intended to+apply and the section as a whole is intended to apply in other+circumstances.++It is not the purpose of this section to induce you to infringe any+patents or other property right claims or to contest validity of any+such claims; this section has the sole purpose of protecting the+integrity of the free software distribution system, which is+implemented by public license practices.  Many people have made+generous contributions to the wide range of software distributed+through that system in reliance on consistent application of that+system; it is up to the author/donor to decide if he or she is willing+to distribute software through any other system and a licensee cannot+impose that choice.++This section is intended to make thoroughly clear what is believed to+be a consequence of the rest of this License.++  8. If the distribution and/or use of the Program is restricted in+certain countries either by patents or by copyrighted interfaces, the+original copyright holder who places the Program under this License+may add an explicit geographical distribution limitation excluding+those countries, so that distribution is permitted only in or among+countries not thus excluded.  In such case, this License incorporates+the limitation as if written in the body of this License.++  9. The Free Software Foundation may publish revised and/or new versions+of the 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 a version number of this License which applies to it and "any+later version", you have the option of following the terms and conditions+either of that version or of any later version published by the Free+Software Foundation.  If the Program does not specify a version number of+this License, you may choose any version ever published by the Free Software+Foundation.++  10. If you wish to incorporate parts of the Program into other free+programs whose distribution conditions are different, write to the author+to ask for permission.  For software which is copyrighted by the Free+Software Foundation, write to the Free Software Foundation; we sometimes+make exceptions for this.  Our decision will be guided by the two goals+of preserving the free status of all derivatives of our free software and+of promoting the sharing and reuse of software generally.++                     NO WARRANTY++  11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, 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.++  12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING+WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR+REDISTRIBUTE 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.++              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+convey 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 2 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, write to the Free Software Foundation, Inc.,+    51 Franklin Street, Fifth Floor, Boston, MA 02110-1301 USA.++Also add information on how to contact you by electronic and paper mail.++If the program is interactive, make it output a short notice like this+when it starts in an interactive mode:++    Gnomovision version 69, Copyright (C) year name of author+    Gnomovision 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, the commands you use may+be called something other than `show w' and `show c'; they could even be+mouse-clicks or menu items--whatever suits your program.++You should also get your employer (if you work as a programmer) or your+school, if any, to sign a "copyright disclaimer" for the program, if+necessary.  Here is a sample; alter the names:++  Yoyodyne, Inc., hereby disclaims all copyright interest in the program+  `Gnomovision' (which makes passes at compilers) written by James Hacker.++  <signature of Ty Coon>, 1 April 1989+  Ty Coon, President of Vice++This 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.
