    82  Everyone is permitted to copy and distribute verbatim copies

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

    84 

    85                             Preamble

    86 

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

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

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

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

    91 General Public License applies to most of the Free Software

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

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

    94 the GNU Lesser General Public License instead.)  You can apply it to

    95 your programs, too.

    96 

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

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

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

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

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

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

   103 

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

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

   106 These restrictions translate to certain responsibilities for you if you

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

   108 

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

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

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

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

   113 rights.

   114 

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

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

   117 distribute and/or modify the software.

   118 

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

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

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

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

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

   124 authors' reputations.

   125 

   126   Finally, any free program is threatened constantly by software

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

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

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

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

   131 

   132   The precise terms and conditions for copying, distribution and

   133 modification follow.

   134 

   135                     GNU GENERAL PUBLIC LICENSE

   136    TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION

   137 

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

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

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

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

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

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

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

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

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

   147 

   148 Activities other than copying, distribution and modification are not

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

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

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

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

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

   154 

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

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

   157 conspicuously and appropriately publish on each copy an appropriate

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

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

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

   161 along with the Program.

   162 

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

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

   165 

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

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

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

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

   170 

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

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

   173 

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

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

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

   177     parties under the terms of this License.

   178 

   179     c) If the modified program normally reads commands interactively

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

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

   182     announcement including an appropriate copyright notice and a

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

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

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

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

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

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

   189 

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

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

   192 and can be reasonably considered independent and separate works in

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

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

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

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

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

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

   199 

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

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

   202 exercise the right to control the distribution of derivative or

   203 collective works based on the Program.

   204 

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

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

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

   208 the scope of this License.

   209 

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

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

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

   213 

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

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

   216     1 and 2 above on a medium customarily used for software interchange; or,

   217 

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

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

   220     cost of physically performing source distribution, a complete

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

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

   223     customarily used for software interchange; or,

   224 

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

   226     to distribute corresponding source code.  (This alternative is

   227     allowed only for noncommercial distribution and only if you

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

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

   230 

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

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

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

   234 associated interface definition files, plus the scripts used to

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

   236 special exception, the source code distributed need not include

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

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

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

   240 itself accompanies the executable.

   241 

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

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

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

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

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

   247 

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

   249 except as expressly provided under this License.  Any attempt

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

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

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

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

   254 parties remain in full compliance.

   255 

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

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

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

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

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

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

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

   263 the Program or works based on it.

   264 

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

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

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

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

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

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

   271 this License.

   272 

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

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

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

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

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

   278 distribute so as to satisfy simultaneously your obligations under this

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

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

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

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

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

   284 refrain entirely from distribution of the Program.

   285 

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

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

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

   289 circumstances.

   290 

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

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

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

   294 integrity of the free software distribution system, which is

   295 implemented by public license practices.  Many people have made

   296 generous contributions to the wide range of software distributed

   297 through that system in reliance on consistent application of that

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

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

   300 impose that choice.

   301 

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

   303 be a consequence of the rest of this License.

   304 

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

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

   307 original copyright holder who places the Program under this License

   308 may add an explicit geographical distribution limitation excluding

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

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

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

   312 

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

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

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

   316 address new problems or concerns.

   317 

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

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

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

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

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

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

   324 Foundation.

   325 

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

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

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

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

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

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

   332 of promoting the sharing and reuse of software generally.

   333 

   334                             NO WARRANTY

   335 

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

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

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

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

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

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

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

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

   344 REPAIR OR CORRECTION.

   345 

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

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

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

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

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

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

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

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

   354 POSSIBILITY OF SUCH DAMAGES.

   355 

   356                      END OF TERMS AND CONDITIONS

   357 

   358             How to Apply These Terms to Your New Programs

   359 

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

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

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

   363 

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

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

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

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

   368 

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

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

   371 

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

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

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

   375     (at your option) any later version.

   376 

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

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

   379     MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.  See the

   380     GNU General Public License for more details.

   381 

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

   383     with this program; if not, write to the Free Software Foundation, Inc.,

   384     51 Franklin Street, Fifth Floor, Boston, MA 02110-1301 USA.

   385 

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

   387 

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

   389 when it starts in an interactive mode:

   390 

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

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

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

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

   395 

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

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

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

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

   400 

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

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

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

   404 

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

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

   410 

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

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

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

   414 library.  If this is what you want to do, use the GNU Lesser General

   415 Public License instead of this License.

  1101 

  1102  Copyright (C) 2007 Free Software Foundation, Inc. <http://fsf.org/>

  1103  Everyone is permitted to copy and distribute verbatim copies

  1104  of this license document, but changing it is not allowed.

  1105 

  1106 

  1107   This version of the GNU Lesser General Public License incorporates

  1108 the terms and conditions of version 3 of the GNU General Public

  1109 License, supplemented by the additional permissions listed below.

  1110 

  1111   0. Additional Definitions.

  1112 

  1113   As used herein, "this License" refers to version 3 of the GNU Lesser

  1114 General Public License, and the "GNU GPL" refers to version 3 of the GNU

  1115 General Public License.

  1116 

  1117   "The Library" refers to a covered work governed by this License,

  1118 other than an Application or a Combined Work as defined below.

  1119 

  1120   An "Application" is any work that makes use of an interface provided

  1121 by the Library, but which is not otherwise based on the Library.

  1122 Defining a subclass of a class defined by the Library is deemed a mode

  1123 of using an interface provided by the Library.

  1124 

  1125   A "Combined Work" is a work produced by combining or linking an

  1126 Application with the Library.  The particular version of the Library

  1127 with which the Combined Work was made is also called the "Linked

  1128 Version".

  1129 

  1130   The "Minimal Corresponding Source" for a Combined Work means the

  1131 Corresponding Source for the Combined Work, excluding any source code

  1132 for portions of the Combined Work that, considered in isolation, are

  1133 based on the Application, and not on the Linked Version.

  1134 

  1135   The "Corresponding Application Code" for a Combined Work means the

  1136 object code and/or source code for the Application, including any data

  1137 and utility programs needed for reproducing the Combined Work from the

  1138 Application, but excluding the System Libraries of the Combined Work.

  1139 

  1140   1. Exception to Section 3 of the GNU GPL.

  1141 

  1142   You may convey a covered work under sections 3 and 4 of this License

  1143 without being bound by section 3 of the GNU GPL.

  1144 

  1145   2. Conveying Modified Versions.

  1146 

  1147   If you modify a copy of the Library, and, in your modifications, a

  1148 facility refers to a function or data to be supplied by an Application

  1149 that uses the facility (other than as an argument passed when the

  1150 facility is invoked), then you may convey a copy of the modified

  1151 version:

  1152 

  1153    a) under this License, provided that you make a good faith effort to

  1154    ensure that, in the event an Application does not supply the

  1155    function or data, the facility still operates, and performs

  1156    whatever part of its purpose remains meaningful, or

  1157 

  1158    b) under the GNU GPL, with none of the additional permissions of

  1159    this License applicable to that copy.

  1160 

  1161   3. Object Code Incorporating Material from Library Header Files.

  1162 

  1163   The object code form of an Application may incorporate material from

  1164 a header file that is part of the Library.  You may convey such object

  1165 code under terms of your choice, provided that, if the incorporated

  1166 material is not limited to numerical parameters, data structure

  1167 layouts and accessors, or small macros, inline functions and templates

  1168 (ten or fewer lines in length), you do both of the following:

  1169 

  1170    a) Give prominent notice with each copy of the object code that the

  1171    Library is used in it and that the Library and its use are

  1172    covered by this License.

  1173 

  1174    b) Accompany the object code with a copy of the GNU GPL and this license

  1175    document.

  1176 

  1177   4. Combined Works.

  1178 

  1179   You may convey a Combined Work under terms of your choice that,

  1180 taken together, effectively do not restrict modification of the

  1181 portions of the Library contained in the Combined Work and reverse

  1182 engineering for debugging such modifications, if you also do each of

  1183 the following:

  1184 

  1185    a) Give prominent notice with each copy of the Combined Work that

  1186    the Library is used in it and that the Library and its use are

  1187    covered by this License.

  1188 

  1189    b) Accompany the Combined Work with a copy of the GNU GPL and this license

  1190    document.

  1191 

  1192    c) For a Combined Work that displays copyright notices during

  1193    execution, include the copyright notice for the Library among

  1194    these notices, as well as a reference directing the user to the

  1195    copies of the GNU GPL and this license document.

  1196 

  1197    d) Do one of the following:

  1198 

  1199        0) Convey the Minimal Corresponding Source under the terms of this

  1200        License, and the Corresponding Application Code in a form

  1201        suitable for, and under terms that permit, the user to

  1202        recombine or relink the Application with a modified version of

  1203        the Linked Version to produce a modified Combined Work, in the

  1204        manner specified by section 6 of the GNU GPL for conveying

  1205        Corresponding Source.

  1206 

  1207        1) Use a suitable shared library mechanism for linking with the

  1208        Library.  A suitable mechanism is one that (a) uses at run time

  1209        a copy of the Library already present on the user's computer

  1210        system, and (b) will operate properly with a modified version

  1211        of the Library that is interface-compatible with the Linked

  1212        Version.

  1213 

  1214    e) Provide Installation Information, but only if you would otherwise

  1215    be required to provide such information under section 6 of the

  1216    GNU GPL, and only to the extent that such information is

  1217    necessary to install and execute a modified version of the

  1218    Combined Work produced by recombining or relinking the

  1219    Application with a modified version of the Linked Version. (If

  1220    you use option 4d0, the Installation Information must accompany

  1221    the Minimal Corresponding Source and Corresponding Application

  1222    Code. If you use option 4d1, you must provide the Installation

  1223    Information in the manner specified by section 6 of the GNU GPL

  1224    for conveying Corresponding Source.)

  1225 

  1226   5. Combined Libraries.

  1227 

  1228   You may place library facilities that are a work based on the

  1229 Library side by side in a single library together with other library

  1230 facilities that are not Applications and are not covered by this

  1231 License, and convey such a combined library under terms of your

  1232 choice, if you do both of the following:

  1233 

  1234    a) Accompany the combined library with a copy of the same work based

  1235    on the Library, uncombined with any other library facilities,

  1236    conveyed under the terms of this License.

  1237 

  1238    b) Give prominent notice with the combined library that part of it

  1239    is a work based on the Library, and explaining where to find the

  1240    accompanying uncombined form of the same work.

  1241 

  1242   6. Revised Versions of the GNU Lesser General Public License.

  1243 

  1244   The Free Software Foundation may publish revised and/or new versions

  1245 of the GNU Lesser General Public License from time to time. Such new

  1246 versions will be similar in spirit to the present version, but may

  1247 differ in detail to address new problems or concerns.

  1248 

  1249   Each version is given a distinguishing version number. If the

  1250 Library as you received it specifies that a certain numbered version

  1251 of the GNU Lesser General Public License "or any later version"

  1252 applies to it, you have the option of following the terms and

  1253 conditions either of that published version or of any later version

  1254 published by the Free Software Foundation. If the Library as you

  1255 received it does not specify a version number of the GNU Lesser

  1256 General Public License, you may choose any version of the GNU Lesser

  1257 General Public License ever published by the Free Software Foundation.

  1258 

  1259   If the Library as you received it specifies that a proxy can decide

  1260 whether future versions of the GNU Lesser General Public License shall

  1261 apply, that proxy's public statement of acceptance of any version is

  1262 permanent authorization for you to choose that version for the

  1263 Library.
