  13 <h3>GNU GENERAL PUBLIC LICENSE</h3>
  14 <p>
  15 Version 2, June 1991
  16 </p>
  17
  18 <pre>
  19 Copyright (C) 1989, 1991 Free Software Foundation, Inc.
  20 51 Franklin Street, Fifth Floor, Boston, MA  02110-1301, USA
  21
  22 Everyone is permitted to copy and distribute verbatim copies
  23 of this license document, but changing it is not allowed.
  24 </pre>
  25
  26 <h3>Preamble</h3>
  27
  28 <p>
  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 Lesser General Public License instead.)  You can apply it to
  37 your programs, too.
  38 </p>
  39
  40 <p>
  41   When we speak of free software, we are referring to freedom, not
  42 price.  Our General Public Licenses are designed to make sure that you
  43 have the freedom to distribute copies of free software (and charge for
  44 this service if you wish), that you receive source code or can get it
  45 if you want it, that you can change the software or use pieces of it
  46 in new free programs; and that you know you can do these things.
  47 </p>
  48
  49 <p>
  50   To protect your rights, we need to make restrictions that forbid
  51 anyone to deny you these rights or to ask you to surrender the rights.
  52 These restrictions translate to certain responsibilities for you if you
  53 distribute copies of the software, or if you modify it.
  54 </p>
  55
  56 <p>
  57   For example, if you distribute copies of such a program, whether
  58 gratis or for a fee, you must give the recipients all the rights that
  59 you have.  You must make sure that they, too, receive or can get the
  60 source code.  And you must show them these terms so they know their
  61 rights.
  62 </p>
  63
  64 <p>
  65   We protect your rights with two steps: (1) copyright the software, and
  66 (2) offer you this license which gives you legal permission to copy,
  67 distribute and/or modify the software.
  68 </p>
  69
  70 <p>
  71   Also, for each author's protection and ours, we want to make certain
  72 that everyone understands that there is no warranty for this free
  73 software.  If the software is modified by someone else and passed on, we
  74 want its recipients to know that what they have is not the original, so
  75 that any problems introduced by others will not reflect on the original
  76 authors' reputations.
  77 </p>
  78
  79 <p>
  80   Finally, any free program is threatened constantly by software
  81 patents.  We wish to avoid the danger that redistributors of a free
  82 program will individually obtain patent licenses, in effect making the
  83 program proprietary.  To prevent this, we have made it clear that any
  84 patent must be licensed for everyone's free use or not licensed at all.
  85 </p>
  86
  87 <p>
  88   The precise terms and conditions for copying, distribution and
  89 modification follow.
  90 </p>
  91
  92
  93 <h3>TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION</h3>
  94
  95
  96 <p>
  97 <strong>0.</strong>
  98  This License applies to any program or other work which contains
  99 a notice placed by the copyright holder saying it may be distributed
 100 under the terms of this General Public License.  The "Program", below,
 101 refers to any such program or work, and a "work based on the Program"
 102 means either the Program or any derivative work under copyright law:
 103 that is to say, a work containing the Program or a portion of it,
 104 either verbatim or with modifications and/or translated into another
 105 language.  (Hereinafter, translation is included without limitation in
 106 the term "modification".)  Each licensee is addressed as "you".
 107 </p>
 108
 109 <p>
 110 Activities other than copying, distribution and modification are not
 111 covered by this License; they are outside its scope.  The act of
 112 running the Program is not restricted, and the output from the Program
 113 is covered only if its contents constitute a work based on the
 114 Program (independent of having been made by running the Program).
 115 Whether that is true depends on what the Program does.
 116 </p>
 117
 118 <p>
 119 <strong>1.</strong>
 120  You may copy and distribute verbatim copies of the Program's
 121 source code as you receive it, in any medium, provided that you
 122 conspicuously and appropriately publish on each copy an appropriate
 123 copyright notice and disclaimer of warranty; keep intact all the
 124 notices that refer to this License and to the absence of any warranty;
 125 and give any other recipients of the Program a copy of this License
 126 along with the Program.
 127 </p>
 128
 129 <p>
 130 You may charge a fee for the physical act of transferring a copy, and
 131 you may at your option offer warranty protection in exchange for a fee.
 132 </p>
 133
 134 <p>
 135 <strong>2.</strong>
 136  You may modify your copy or copies of the Program or any portion
 137 of it, thus forming a work based on the Program, and copy and
 138 distribute such modifications or work under the terms of Section 1
 139 above, provided that you also meet all of these conditions:
 140 </p>
 141
 142 <dl>
 143   <dt></dt>
 144     <dd>
 145       <strong>a)</strong>
 146       You must cause the modified files to carry prominent notices
 147       stating that you changed the files and the date of any change.
 148     </dd>
 149   <dt></dt>
 150     <dd>
 151       <strong>b)</strong>
 152       You must cause any work that you distribute or publish, that in
 153       whole or in part contains or is derived from the Program or any
 154       part thereof, to be licensed as a whole at no charge to all third
 155       parties under the terms of this License.
 156     </dd>
 157   <dt></dt>
 158     <dd>
 159       <strong>c)</strong>
 160       If the modified program normally reads commands interactively
 161       when run, you must cause it, when started running for such
 162       interactive use in the most ordinary way, to print or display an
 163       announcement including an appropriate copyright notice and a
 164       notice that there is no warranty (or else, saying that you provide
 165       a warranty) and that users may redistribute the program under
 166       these conditions, and telling the user how to view a copy of this
 167       License.  (Exception: if the Program itself is interactive but
 168       does not normally print such an announcement, your work based on
 169       the Program is not required to print an announcement.)
 170     </dd>
 171 </dl>
 172
 173 <p>
 174 These requirements apply to the modified work as a whole.  If
 175 identifiable sections of that work are not derived from the Program,
 176 and can be reasonably considered independent and separate works in
 177 themselves, then this License, and its terms, do not apply to those
 178 sections when you distribute them as separate works.  But when you
 179 distribute the same sections as part of a whole which is a work based
 180 on the Program, the distribution of the whole must be on the terms of
 181 this License, whose permissions for other licensees extend to the
 182 entire whole, and thus to each and every part regardless of who wrote it.
 183 </p>
 184
 185 <p>
 186 Thus, it is not the intent of this section to claim rights or contest
 187 your rights to work written entirely by you; rather, the intent is to
 188 exercise the right to control the distribution of derivative or
 189 collective works based on the Program.
 190 </p>
 191
 192 <p>
 193 In addition, mere aggregation of another work not based on the Program
 194 with the Program (or with a work based on the Program) on a volume of
 195 a storage or distribution medium does not bring the other work under
 196 the scope of this License.
 197 </p>
 198
 199 <p>
 200 <strong>3.</strong>
 201  You may copy and distribute the Program (or a work based on it,
 202 under Section 2) in object code or executable form under the terms of
 203 Sections 1 and 2 above provided that you also do one of the following:
 204 </p>
 205
 206 <!-- we use this doubled UL to get the sub-sections indented, -->
 207 <!-- while making the bullets as unobvious as possible. -->
 208
 209 <dl>
 210   <dt></dt>
 211     <dd>
 212       <strong>a)</strong>
 213       Accompany it with the complete corresponding machine-readable
 214       source code, which must be distributed under the terms of Sections
 215       1 and 2 above on a medium customarily used for software interchange; or,
 216     </dd>
 217   <dt></dt>
 218     <dd>
 219       <strong>b)</strong>
 220       Accompany it with a written offer, valid for at least three
 221       years, to give any third party, for a charge no more than your
 222       cost of physically performing source distribution, a complete
 223       machine-readable copy of the corresponding source code, to be
 224       distributed under the terms of Sections 1 and 2 above on a medium
 225       customarily used for software interchange; or,
 226     </dd>
 227   <dt></dt>
 228     <dd>
 229       <strong>c)</strong>
 230       Accompany it with the information you received as to the offer
 231       to distribute corresponding source code.  (This alternative is
 232       allowed only for noncommercial distribution and only if you
 233       received the program in object code or executable form with such
 234       an offer, in accord with Subsection b above.)
 235     </dd>
 236 </dl>
 237
 238 <p>
 239 The source code for a work means the preferred form of the work for
 240 making modifications to it.  For an executable work, complete source
 241 code means all the source code for all modules it contains, plus any
 242 associated interface definition files, plus the scripts used to
 243 control compilation and installation of the executable.  However, as a
 244 special exception, the source code distributed need not include
 245 anything that is normally distributed (in either source or binary
 246 form) with the major components (compiler, kernel, and so on) of the
 247 operating system on which the executable runs, unless that component
 248 itself accompanies the executable.
 249 </p>
 250
 251 <p>
 252 If distribution of executable or object code is made by offering
 253 access to copy from a designated place, then offering equivalent
 254 access to copy the source code from the same place counts as
 255 distribution of the source code, even though third parties are not
 256 compelled to copy the source along with the object code.
 257 </p>
 258
 259 <p>
 260 <strong>4.</strong>
 261  You may not copy, modify, sublicense, or distribute the Program
 262 except as expressly provided under this License.  Any attempt
 263 otherwise to copy, modify, sublicense or distribute the Program is
 264 void, and will automatically terminate your rights under this License.
 265 However, parties who have received copies, or rights, from you under
 266 this License will not have their licenses terminated so long as such
 267 parties remain in full compliance.
 268 </p>
 269
 270 <p>
 271 <strong>5.</strong>
 272  You are not required to accept this License, since you have not
 273 signed it.  However, nothing else grants you permission to modify or
 274 distribute the Program or its derivative works.  These actions are
 275 prohibited by law if you do not accept this License.  Therefore, by
 276 modifying or distributing the Program (or any work based on the
 277 Program), you indicate your acceptance of this License to do so, and
 278 all its terms and conditions for copying, distributing or modifying
 279 the Program or works based on it.
 280 </p>
 281
 282 <p>
 283 <strong>6.</strong>
 284  Each time you redistribute the Program (or any work based on the
 285 Program), the recipient automatically receives a license from the
 286 original licensor to copy, distribute or modify the Program subject to
 287 these terms and conditions.  You may not impose any further
 288 restrictions on the recipients' exercise of the rights granted herein.
 289 You are not responsible for enforcing compliance by third parties to
 290 this License.
 291 </p>
 292
 293 <p>
 294 <strong>7.</strong>
 295  If, as a consequence of a court judgment or allegation of patent
 296 infringement or for any other reason (not limited to patent issues),
 297 conditions are imposed on you (whether by court order, agreement or
 298 otherwise) that contradict the conditions of this License, they do not
 299 excuse you from the conditions of this License.  If you cannot
 300 distribute so as to satisfy simultaneously your obligations under this
 301 License and any other pertinent obligations, then as a consequence you
 302 may not distribute the Program at all.  For example, if a patent
 303 license would not permit royalty-free redistribution of the Program by
 304 all those who receive copies directly or indirectly through you, then
 305 the only way you could satisfy both it and this License would be to
 306 refrain entirely from distribution of the Program.
 307 </p>
 308
 309 <p>
 310 If any portion of this section is held invalid or unenforceable under
 311 any particular circumstance, the balance of the section is intended to
 312 apply and the section as a whole is intended to apply in other
 313 circumstances.
 314 </p>
 315
 316 <p>
 317 It is not the purpose of this section to induce you to infringe any
 318 patents or other property right claims or to contest validity of any
 319 such claims; this section has the sole purpose of protecting the
 320 integrity of the free software distribution system, which is
 321 implemented by public license practices.  Many people have made
 322 generous contributions to the wide range of software distributed
 323 through that system in reliance on consistent application of that
 324 system; it is up to the author/donor to decide if he or she is willing
 325 to distribute software through any other system and a licensee cannot
 326 impose that choice.
 327 </p>
 328
 329 <p>
 330 This section is intended to make thoroughly clear what is believed to
 331 be a consequence of the rest of this License.
 332 </p>
 333
 334 <p>
 335 <strong>8.</strong>
 336  If the distribution and/or use of the Program is restricted in
 337 certain countries either by patents or by copyrighted interfaces, the
 338 original copyright holder who places the Program under this License
 339 may add an explicit geographical distribution limitation excluding
 340 those countries, so that distribution is permitted only in or among
 341 countries not thus excluded.  In such case, this License incorporates
 342 the limitation as if written in the body of this License.
 343 </p>
 344
 345 <p>
 346 <strong>9.</strong>
 347  The Free Software Foundation may publish revised and/or new versions
 348 of the General Public License from time to time.  Such new versions will
 349 be similar in spirit to the present version, but may differ in detail to
 350 address new problems or concerns.
 351 </p>
 352
 353 <p>
 354 Each version is given a distinguishing version number.  If the Program
 355 specifies a version number of this License which applies to it and "any
 356 later version", you have the option of following the terms and conditions
 357 either of that version or of any later version published by the Free
 358 Software Foundation.  If the Program does not specify a version number of
 359 this License, you may choose any version ever published by the Free Software
 360 Foundation.
 361 </p>
 362
 363 <p>
 364 <strong>10.</strong>
 365  If you wish to incorporate parts of the Program into other free
 366 programs whose distribution conditions are different, write to the author
 367 to ask for permission.  For software which is copyrighted by the Free
 368 Software Foundation, write to the Free Software Foundation; we sometimes
 369 make exceptions for this.  Our decision will be guided by the two goals
 370 of preserving the free status of all derivatives of our free software and
 371 of promoting the sharing and reuse of software generally.
 372 </p>
 373
 374 <p><strong>NO WARRANTY</strong></p>
 375
 376 <p>
 377 <strong>11.</strong>
 378  BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY
 379 FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW.  EXCEPT WHEN
 380 OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES
 381 PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED
 382 OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF
 383 MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE.  THE ENTIRE RISK AS
 384 TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU.  SHOULD THE
 385 PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING,
 386 REPAIR OR CORRECTION.
 387 </p>
 388
 389 <p>
 390 <strong>12.</strong>
 391  IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
 392 WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR
 393 REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES,
 394 INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING
 395 OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED
 396 TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY
 397 YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER
 398 PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE
 399 POSSIBILITY OF SUCH DAMAGES.
 400 </p>
 401
 402 <h3>END OF TERMS AND CONDITIONS</h3>
 403
 404 <h3>How to Apply These Terms to Your New Programs</h3>
 405
 406 <p>
 407   If you develop a new program, and you want it to be of the greatest
 408 possible use to the public, the best way to achieve this is to make it
 409 free software which everyone can redistribute and change under these terms.
 410 </p>
 411
 412 <p>
 413   To do so, attach the following notices to the program.  It is safest
 414 to attach them to the start of each source file to most effectively
 415 convey the exclusion of warranty; and each file should have at least
 416 the "copyright" line and a pointer to where the full notice is found.
 417 </p>
 418
 419 <pre>
 420 <var>one line to give the program's name and an idea of what it does.</var>

 422
 423 This program is free software; you can redistribute it and/or
 424 modify it under the terms of the GNU General Public License
 425 as published by the Free Software Foundation; either version 2
 426 of the License, or (at your option) any later version.
 427
 428 This program is distributed in the hope that it will be useful,
 429 but WITHOUT ANY WARRANTY; without even the implied warranty of
 430 MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.  See the
 431 GNU General Public License for more details.
 432
 433 You should have received a copy of the GNU General Public License
 434 along with this program; if not, write to the Free Software
 435 Foundation, Inc., 51 Franklin Street, Fifth Floor, Boston, MA  02110-1301, USA.
 436 </pre>
 437
 438 <p>
 439 Also add information on how to contact you by electronic and paper mail.
 440 </p>
 441
 442 <p>
 443 If the program is interactive, make it output a short notice like this
 444 when it starts in an interactive mode:

 451 to redistribute it under certain conditions; type `show c'
 452 for details.
 453 </pre>
 454
 455 <p>
 456 The hypothetical commands <samp>`show w'</samp> and <samp>`show c'</samp> should show
 457 the appropriate parts of the General Public License.  Of course, the
 458 commands you use may be called something other than <samp>`show w'</samp> and
 459 <samp>`show c'</samp>; they could even be mouse-clicks or menu items--whatever
 460 suits your program.
 461 </p>
 462
 463 <p>
 464 You should also get your employer (if you work as a programmer) or your
 465 school, if any, to sign a "copyright disclaimer" for the program, if
 466 necessary.  Here is a sample; alter the names:

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