| The GNU General Public License (GPL)
 | |
| 
 | |
| Version 2, June 1991
 | |
| 
 | |
| Copyright (C) 1989, 1991 Free Software Foundation, Inc.
 | |
| 59 Temple Place, Suite 330, Boston, MA 02111-1307 USA
 | |
| 
 | |
| Everyone is permitted to copy and distribute verbatim copies of this license
 | |
| document, but changing it is not allowed.
 | |
| 
 | |
| Preamble
 | |
| 
 | |
| The licenses for most software are designed to take away your freedom to share
 | |
| and change it.  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 Library 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.
 | |
| 
 | |
| 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., 59
 | |
|     Temple Place, Suite 330, Boston, MA 02111-1307 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.

| 
 | |
| 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 Library General Public
 | |
| License instead of this License.

| 
 | |
| "CLASSPATH" EXCEPTION TO THE GPL
 | |
| 
 | |
| Certain source files distributed by Oracle America and/or its affiliates are
 | |
| subject to the following clarification and special exception to the GPL, but
 | |
| only where Oracle has expressly included in the particular source file's header
 | |
| the words "Oracle designates this particular file as subject to the "Classpath"
 | |
| exception as provided by Oracle in the LICENSE file that accompanied this code."
 | |
| 
 | |
|     Linking this library statically or dynamically with other modules is making
 | |
|     a combined work based on this library.  Thus, the terms and conditions of
 | |
|     the GNU General Public License cover the whole combination.
 | |
| 
 | |
|     As a special exception, the copyright holders of this library give you
 | |
|     permission to link this library with independent modules to produce an
 | |
|     executable, regardless of the license terms of these independent modules,
 | |
|     and to copy and distribute the resulting executable under terms of your
 | |
|     choice, provided that you also meet, for each linked independent module,
 | |
|     the terms and conditions of the license of that module.  An independent
 | |
|     module is a module which is not derived from or based on this library.  If
 | |
|     you modify this library, you may extend this exception to your version of
 | |
|     the library, but you are not obligated to do so.  If you do not wish to do
 | |
|     so, delete this exception statement from your version.
 |
