    20 

    21  Copyright (C) 1989, 1991 Free Software Foundation, Inc.

    22                           51 Franklin Street, Fifth Floor,

    23                           Boston, MA 02110-1301, USA.

    24  Everyone is permitted to copy and distribute verbatim copies

    25  of this license document, but changing it is not allowed.

    26 

    27                             Preamble

    28 

    29   The licenses for most software are designed to take away your

    30 freedom to share and change it.  By contrast, the GNU General Public

    31 License is intended to guarantee your freedom to share and change free

    32 software--to make sure the software is free for all its users.  This

    33 General Public License applies to most of the Free Software

    34 Foundation's software and to any other program whose authors commit to

    35 using it.  (Some other Free Software Foundation software is covered by

    36 the GNU Library General Public License instead.)  You can apply it to

    37 your programs, too.

    38 

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

    40 price.  Our General Public Licenses are designed to make sure that you

    41 have the freedom to distribute copies of free software (and charge for

    42 this service if you wish), that you receive source code or can get it

    43 if you want it, that you can change the software or use pieces of it

    44 in new free programs; and that you know you can do these things.

    45 

    46   To protect your rights, we need to make restrictions that forbid

    47 anyone to deny you these rights or to ask you to surrender the rights.

    48 These restrictions translate to certain responsibilities for you if you

    49 distribute copies of the software, or if you modify it.

    50 

    51   For example, if you distribute copies of such a program, whether

    52 gratis or for a fee, you must give the recipients all the rights that

    53 you have.  You must make sure that they, too, receive or can get the

    54 source code.  And you must show them these terms so they know their

    55 rights.

    56 

    57   We protect your rights with two steps: (1) copyright the software, and

    58 (2) offer you this license which gives you legal permission to copy,

    59 distribute and/or modify the software.

    60 

    61   Also, for each author's protection and ours, we want to make certain

    62 that everyone understands that there is no warranty for this free

    63 software.  If the software is modified by someone else and passed on, we

    64 want its recipients to know that what they have is not the original, so

    65 that any problems introduced by others will not reflect on the original

    66 authors' reputations.

    67 

    68   Finally, any free program is threatened constantly by software

    69 patents.  We wish to avoid the danger that redistributors of a free

    70 program will individually obtain patent licenses, in effect making the

    71 program proprietary.  To prevent this, we have made it clear that any

    72 patent must be licensed for everyone's free use or not licensed at all.

    73 

    74   The precise terms and conditions for copying, distribution and

    75 modification follow.

    76 

    77 

    78                     GNU GENERAL PUBLIC LICENSE

    79    TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION

    80 

    81   0. This License applies to any program or other work which contains

    82 a notice placed by the copyright holder saying it may be distributed

    83 under the terms of this General Public License.  The "Program", below,

    84 refers to any such program or work, and a "work based on the Program"

    85 means either the Program or any derivative work under copyright law:

    86 that is to say, a work containing the Program or a portion of it,

    87 either verbatim or with modifications and/or translated into another

    88 language.  (Hereinafter, translation is included without limitation in

    89 the term "modification".)  Each licensee is addressed as "you".

    90 

    91 Activities other than copying, distribution and modification are not

    92 covered by this License; they are outside its scope.  The act of

    93 running the Program is not restricted, and the output from the Program

    94 is covered only if its contents constitute a work based on the

    95 Program (independent of having been made by running the Program).

    96 Whether that is true depends on what the Program does.

    97 

    98   1. You may copy and distribute verbatim copies of the Program's

    99 source code as you receive it, in any medium, provided that you

   100 conspicuously and appropriately publish on each copy an appropriate

   101 copyright notice and disclaimer of warranty; keep intact all the

   102 notices that refer to this License and to the absence of any warranty;

   103 and give any other recipients of the Program a copy of this License

   104 along with the Program.

   105 

   106 You may charge a fee for the physical act of transferring a copy, and

   107 you may at your option offer warranty protection in exchange for a fee.

   108 

   109   2. You may modify your copy or copies of the Program or any portion

   110 of it, thus forming a work based on the Program, and copy and

   111 distribute such modifications or work under the terms of Section 1

   112 above, provided that you also meet all of these conditions:

   113 

   114     a) You must cause the modified files to carry prominent notices

   115     stating that you changed the files and the date of any change.

   116 

   117     b) You must cause any work that you distribute or publish, that in

   118     whole or in part contains or is derived from the Program or any

   119     part thereof, to be licensed as a whole at no charge to all third

   120     parties under the terms of this License.

   121 

   122     c) If the modified program normally reads commands interactively

   123     when run, you must cause it, when started running for such

   124     interactive use in the most ordinary way, to print or display an

   125     announcement including an appropriate copyright notice and a

   126     notice that there is no warranty (or else, saying that you provide

   127     a warranty) and that users may redistribute the program under

   128     these conditions, and telling the user how to view a copy of this

   129     License.  (Exception: if the Program itself is interactive but

   130     does not normally print such an announcement, your work based on

   131     the Program is not required to print an announcement.)

   132 

   133 

   134 These requirements apply to the modified work as a whole.  If

   135 identifiable sections of that work are not derived from the Program,

   136 and can be reasonably considered independent and separate works in

   137 themselves, then this License, and its terms, do not apply to those

   138 sections when you distribute them as separate works.  But when you

   139 distribute the same sections as part of a whole which is a work based

   140 on the Program, the distribution of the whole must be on the terms of

   141 this License, whose permissions for other licensees extend to the

   142 entire whole, and thus to each and every part regardless of who wrote it.

   143 

   144 Thus, it is not the intent of this section to claim rights or contest

   145 your rights to work written entirely by you; rather, the intent is to

   146 exercise the right to control the distribution of derivative or

   147 collective works based on the Program.

   148 

   149 In addition, mere aggregation of another work not based on the Program

   150 with the Program (or with a work based on the Program) on a volume of

   151 a storage or distribution medium does not bring the other work under

   152 the scope of this License.

   153 

   154   3. You may copy and distribute the Program (or a work based on it,

   155 under Section 2) in object code or executable form under the terms of

   156 Sections 1 and 2 above provided that you also do one of the following:

   157 

   158     a) Accompany it with the complete corresponding machine-readable

   159     source code, which must be distributed under the terms of Sections

   160     1 and 2 above on a medium customarily used for software interchange; or,

   161 

   162     b) Accompany it with a written offer, valid for at least three

   163     years, to give any third party, for a charge no more than your

   164     cost of physically performing source distribution, a complete

   165     machine-readable copy of the corresponding source code, to be

   166     distributed under the terms of Sections 1 and 2 above on a medium

   167     customarily used for software interchange; or,

   168 

   169     c) Accompany it with the information you received as to the offer

   170     to distribute corresponding source code.  (This alternative is

   171     allowed only for noncommercial distribution and only if you

   172     received the program in object code or executable form with such

   173     an offer, in accord with Subsection b above.)

   174 

   175 The source code for a work means the preferred form of the work for

   176 making modifications to it.  For an executable work, complete source

   177 code means all the source code for all modules it contains, plus any

   178 associated interface definition files, plus the scripts used to

   179 control compilation and installation of the executable.  However, as a

   180 special exception, the source code distributed need not include

   181 anything that is normally distributed (in either source or binary

   182 form) with the major components (compiler, kernel, and so on) of the

   183 operating system on which the executable runs, unless that component

   184 itself accompanies the executable.

   185 

   186 If distribution of executable or object code is made by offering

   187 access to copy from a designated place, then offering equivalent

   188 access to copy the source code from the same place counts as

   189 distribution of the source code, even though third parties are not

   190 compelled to copy the source along with the object code.

   191 

   192 

   193   4. You may not copy, modify, sublicense, or distribute the Program

   194 except as expressly provided under this License.  Any attempt

   195 otherwise to copy, modify, sublicense or distribute the Program is

   196 void, and will automatically terminate your rights under this License.

   197 However, parties who have received copies, or rights, from you under

   198 this License will not have their licenses terminated so long as such

   199 parties remain in full compliance.

   200 

   201   5. You are not required to accept this License, since you have not

   202 signed it.  However, nothing else grants you permission to modify or

   203 distribute the Program or its derivative works.  These actions are

   204 prohibited by law if you do not accept this License.  Therefore, by

   205 modifying or distributing the Program (or any work based on the

   206 Program), you indicate your acceptance of this License to do so, and

   207 all its terms and conditions for copying, distributing or modifying

   208 the Program or works based on it.

   209 

   210   6. Each time you redistribute the Program (or any work based on the

   211 Program), the recipient automatically receives a license from the

   212 original licensor to copy, distribute or modify the Program subject to

   213 these terms and conditions.  You may not impose any further

   214 restrictions on the recipients' exercise of the rights granted herein.

   215 You are not responsible for enforcing compliance by third parties to

   216 this License.

   217 

   218   7. If, as a consequence of a court judgment or allegation of patent

   219 infringement or for any other reason (not limited to patent issues),

   220 conditions are imposed on you (whether by court order, agreement or

   221 otherwise) that contradict the conditions of this License, they do not

   222 excuse you from the conditions of this License.  If you cannot

   223 distribute so as to satisfy simultaneously your obligations under this

   224 License and any other pertinent obligations, then as a consequence you

   225 may not distribute the Program at all.  For example, if a patent

   226 license would not permit royalty-free redistribution of the Program by

   227 all those who receive copies directly or indirectly through you, then

   228 the only way you could satisfy both it and this License would be to

   229 refrain entirely from distribution of the Program.

   230 

   231 If any portion of this section is held invalid or unenforceable under

   232 any particular circumstance, the balance of the section is intended to

   233 apply and the section as a whole is intended to apply in other

   234 circumstances.

   235 

   236 It is not the purpose of this section to induce you to infringe any

   237 patents or other property right claims or to contest validity of any

   238 such claims; this section has the sole purpose of protecting the

   239 integrity of the free software distribution system, which is

   240 implemented by public license practices.  Many people have made

   241 generous contributions to the wide range of software distributed

   242 through that system in reliance on consistent application of that

   243 system; it is up to the author/donor to decide if he or she is willing

   244 to distribute software through any other system and a licensee cannot

   245 impose that choice.

   246 

   247 This section is intended to make thoroughly clear what is believed to

   248 be a consequence of the rest of this License.

   249 

   250 

   251   8. If the distribution and/or use of the Program is restricted in

   252 certain countries either by patents or by copyrighted interfaces, the

   253 original copyright holder who places the Program under this License

   254 may add an explicit geographical distribution limitation excluding

   255 those countries, so that distribution is permitted only in or among

   256 countries not thus excluded.  In such case, this License incorporates

   257 the limitation as if written in the body of this License.

   258 

   259   9. The Free Software Foundation may publish revised and/or new versions

   260 of the General Public License from time to time.  Such new versions will

   261 be similar in spirit to the present version, but may differ in detail to

   262 address new problems or concerns.

   263 

   264 Each version is given a distinguishing version number.  If the Program

   265 specifies a version number of this License which applies to it and "any

   266 later version", you have the option of following the terms and conditions

   267 either of that version or of any later version published by the Free

   268 Software Foundation.  If the Program does not specify a version number of

   269 this License, you may choose any version ever published by the Free Software

   270 Foundation.

   271 

   272   10. If you wish to incorporate parts of the Program into other free

   273 programs whose distribution conditions are different, write to the author

   274 to ask for permission.  For software which is copyrighted by the Free

   275 Software Foundation, write to the Free Software Foundation; we sometimes

   276 make exceptions for this.  Our decision will be guided by the two goals

   277 of preserving the free status of all derivatives of our free software and

   278 of promoting the sharing and reuse of software generally.

   279 

   280                             NO WARRANTY

   281 

   282   11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY

   283 FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW.  EXCEPT WHEN

   284 OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES

   285 PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED

   286 OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF

   287 MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE.  THE ENTIRE RISK AS

   288 TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU.  SHOULD THE

   289 PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING,

   290 REPAIR OR CORRECTION.

   291 

   292   12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING

   293 WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR

   294 REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES,

   295 INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING

   296 OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED

   297 TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY

   298 YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER

   299 PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE

   300 POSSIBILITY OF SUCH DAMAGES.

   301 

   302                      END OF TERMS AND CONDITIONS

   303 

   304 

   305         Appendix: How to Apply These Terms to Your New Programs

   306 

   307   If you develop a new program, and you want it to be of the greatest

   308 possible use to the public, the best way to achieve this is to make it

   309 free software which everyone can redistribute and change under these terms.

   310 

   311   To do so, attach the following notices to the program.  It is safest

   312 to attach them to the start of each source file to most effectively

   313 convey the exclusion of warranty; and each file should have at least

   314 the "copyright" line and a pointer to where the full notice is found.

   315 

   316     <one line to give the program's name and a brief idea of what it does.>

   317     Copyright (C) <year>  <name of author>

   318 

   319     This program is free software; you can redistribute it and/or modify

   320     it under the terms of the GNU General Public License as published by

   321     the Free Software Foundation; either version 2 of the License, or

   322     (at your option) any later version.

   323 

   324     This program is distributed in the hope that it will be useful,

   325     but WITHOUT ANY WARRANTY; without even the implied warranty of

   326     MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.  See the

   327     GNU General Public License for more details.

   328 

   329     You should have received a copy of the GNU General Public License

   330     along with this program; if not, write to the Free Software Foundation,

   331     Inc., 51 Franklin Street, Fifth Floor, Boston, MA 02110-1301, USA.

   332 

   333 Also add information on how to contact you by electronic and paper mail.

   334 

   335 If the program is interactive, make it output a short notice like this

   336 when it starts in an interactive mode:

   337 

   338     Gnomovision version 69, Copyright (C) year  name of author

   339     Gnomovision comes with ABSOLUTELY NO WARRANTY; for details type `show w'.

   340     This is free software, and you are welcome to redistribute it

   341     under certain conditions; type `show c' for details.

   342 

   343 The hypothetical commands `show w' and `show c' should show the appropriate

   344 parts of the General Public License.  Of course, the commands you use may

   345 be called something other than `show w' and `show c'; they could even be

   346 mouse-clicks or menu items--whatever suits your program.

   347 

   348 You should also get your employer (if you work as a programmer) or your

   349 school, if any, to sign a "copyright disclaimer" for the program, if

   350 necessary.  Here is a sample; alter the names:

   351 

   352   Yoyodyne, Inc., hereby disclaims all copyright interest in the program

   353   `Gnomovision' (which makes passes at compilers) written by James Hacker.

   357 

   358 This General Public License does not permit incorporating your program into

   359 proprietary programs.  If your program is a subroutine library, you may

   360 consider it more useful to permit linking proprietary applications with the

   361 library.  If this is what you want to do, use the GNU Library General

   362 Public License instead of this License.
