  325. EXHIBIT A - GNU GENERAL PUBLIC LICENSE
  326. GNU GENERAL PUBLIC LICENSE
  327. Version 2, June 1991
  328. Copyright (C) 1989, 1991 Free Software Foundation, Inc. 675 Mass Ave,
  329. Cambridge, MA 02139, USA. Everyone is permitted to copy and distribute
  330. verbatim copies of this license document, but changing it is not
  331. allowed.
  332. Preamble
  333. The licenses for most software are designed to take away your freedom
  334. to share and change it. By contrast, the GNU General Public License
  335. is intended to guarantee your freedom to share and change free
  336. software--to make sure the software is free for all its users. This
  337. General Public License applies to most of the Free Software
  338. Foundation's software and to any other program whose authors commit to
  339. using it. (Some other Free Software Foundation software is covered by
  340. the GNU Library General Public License instead.) You can apply it to
  341. your programs, too.
  342. When we speak of free software, we are referring to freedom, not
  343. price. Our General Public Licenses are designed to make sure that you
  344. have the freedom to distribute copies of free software (and charge for
  345. this service if you wish), that you receive source code or can get it
  346. if you want it, that you can change the software or use pieces of it
  347. in new free programs; and that you know you can do these things.
  348. To protect your rights, we need to make restrictions that forbid
  349. anyone to deny you these rights or to ask you to surrender the rights.
  350. These restrictions translate to certain responsibilities for you if
  351. you distribute copies of the software, or if you modify it.
  352. For example, if you distribute copies of such a program, whether
  353. gratis or for a fee, you must give the recipients all the rights that
  354. you have. You must make sure that they, too, receive or can get the
  355. source code. And you must show them these terms so they know their
  356. rights.
  357. We protect your rights with two steps: (1) copyright the software, and
  358. (2) offer you this license which gives you legal permission to copy,
  359. distribute and/or modify the software.
  360. Also, for each author's protection and ours, we want to make certain
  361. that everyone understands that there is no warranty for this free
  362. software. If the software is modified by someone else and passed on,
  363. we want its recipients to know that what they have is not the
  364. original, so that any problems introduced by others will not reflect
  365. on the original authors' reputations.
  366. Finally, any free program is threatened constantly by software
  367. patents. We wish to avoid the danger that redistributors of a free
  368. program will individually obtain patent licenses, in effect making the
  369. program proprietary. To prevent this, we have made it clear that any
  370. patent must be licensed for everyone's free use or not licensed at
  371. all.
  372. The precise terms and conditions for copying, distribution and
  373. modification follow.
  374. GNU GENERAL PUBLIC LICENSE
  375. TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
  376. 0. This License applies to any program or other work which contains a
  377. notice placed by the copyright holder saying it may be distributed
  378. under the terms of this General Public License. The "Program", below,
  379. refers to any such program or work, and a "work based on the Program"
  380. means either the Program or any derivative work under copyright law:
  381. that is to say, a work containing the Program or a portion of it,
  382. either verbatim or with modifications and/or translated into another
  383. language. (Hereinafter, translation is included without limitation in
  384. the term "modification".) Each licensee is addressed as "you".
  385. Activities other than copying, distribution and modification are not
  386. covered by this License; they are outside its scope. The act of
  387. running the Program is not restricted, and the output from the Program
  388. is covered only if its contents constitute a work based on the Program
  389. (independent of having been made by running the Program). Whether
  390. that is true depends on what the Program does.
  391. 1. You may copy and distribute verbatim copies of the Program's
  392. source code as you receive it, in any medium, provided that you
  393. conspicuously and appropriately publish on each copy an appropriate
  394. copyright notice and disclaimer of warranty; keep intact all the
  395. notices that refer to this License and to the absence of any warranty;
  396. and give any other recipients of the Program a copy of this License
  397. along with the Program.
  398. You may charge a fee for the physical act of transferring a copy, and
  399. you may at your option offer warranty protection in exchange for a
  400. fee.
  401. 2. You may modify your copy or copies of the Program or any portion
  402. of it, thus forming a work based on the Program, and copy and
  403. distribute such modifications or work under the terms of Section 1
  404. above, provided that you also meet all of these conditions:
  405. a) You must cause the modified files to carry prominent notices
  406. stating that you changed the files and the date of any change.
  407. b) You must cause any work that you distribute or publish, that in
  408. whole or in part contains or is derived from the Program or any part
  409. thereof, to be licensed as a whole at no charge to all third parties
  410. under the terms of this License.
  411. c) If the modified program normally reads commands interactively when
  412. run, you must cause it, when started running for such interactive use
  413. in the most ordinary way, to print or display an announcement
  414. including an appropriate copyright notice and a notice that there is
  415. no warranty (or else, saying that you provide a warranty) and that
  416. users may redistribute the program under these conditions, and telling
  417. the user how to view a copy of this License. (Exception: if the
  418. Program itself is interactive but does not normally print such an
  419. announcement, your work based on the Program is not required to print
  420. an announcement.)
  421. These requirements apply to the modified work as a whole. If
  422. identifiable sections of that work are not derived from the Program,
  423. and can be reasonably considered independent and separate works in
  424. themselves, then this License, and its terms, do not apply to those
  425. sections when you distribute them as separate works. But when you
  426. distribute the same sections as part of a whole which is a work based
  427. on the Program, the distribution of the whole must be on the terms of
  428. this License, whose permissions for other licensees extend to the
  429. entire whole, and thus to each and every part regardless of who wrote
  430. it.
  431. Thus, it is not the intent of this section to claim rights or contest
  432. your rights to work written entirely by you; rather, the intent is to
  433. exercise the right to control the distribution of derivative or
  434. collective works based on the Program.
  435. In addition, mere aggregation of another work not based on the Program
  436. with the Program (or with a work based on the Program) on a volume of
  437. a storage or distribution medium does not bring the other work under
  438. the scope of this License.
  439. 3. You may copy and distribute the Program (or a work based on it,
  440. under Section 2) in object code or executable form under the terms of
  441. Sections 1 and 2 above provided that you also do one of the following:
  442. a) Accompany it with the complete corresponding machine-readable
  443. source code, which must be distributed under the terms of Sections 1
  444. and 2 above on a medium customarily used for software interchange; or,
  445. b) Accompany it with a written offer, valid for at least three years,
  446. to give any third party, for a charge no more than your cost of
  447. physically performing source distribution, a complete machine-readable
  448. copy of the corresponding source code, to be distributed under the
  449. terms of Sections 1 and 2 above on a medium customarily used for
  450. software interchange; or,
  451. c) Accompany it with the information you received as to the offer to
  452. distribute corresponding source code. (This alternative is allowed
  453. only for noncommercial distribution and only if you received the
  454. program in object code or executable form with such an offer, in
  455. accord with Subsection b above.)
  456. The source code for a work means the preferred form of the work for
  457. making modifications to it. For an executable work, complete source
  458. code means all the source code for all modules it contains, plus any
  459. associated interface definition files, plus the scripts used to
  460. control compilation and installation of the executable. However, as a
  461. special exception, the source code distributed need not include
  462. anything that is normally distributed (in either source or binary
  463. form) with the major components (compiler, kernel, and so on) of the
  464. operating system on which the executable runs, unless that component
  465. itself accompanies the executable.
  466. If distribution of executable or object code is made by offering
  467. access to copy from a designated place, then offering equivalent
  468. access to copy the source code from the same place counts as
  469. distribution of the source code, even though third parties are not
  470. compelled to copy the source along with the object code.
  471. 4. You may not copy, modify, sublicense, or distribute the Program
  472. except as expressly provided under this License. Any attempt
  473. otherwise to copy, modify, sublicense or distribute the Program is
  474. void, and will automatically terminate your rights under this License.
  475. However, parties who have received copies, or rights, from you under
  476. this License will not have their licenses terminated so long as such
  477. parties remain in full compliance.
  478. 5. You are not required to accept this License, since you have not
  479. signed it. However, nothing else grants you permission to modify or
  480. distribute the Program or its derivative works. These actions are
  481. prohibited by law if you do not accept this License. Therefore, by
  482. modifying or distributing the Program (or any work based on the
  483. Program), you indicate your acceptance of this License to do so, and
  484. all its terms and conditions for copying, distributing or modifying
  485. the Program or works based on it.
  486. 6. Each time you redistribute the Program (or any work based on the
  487. Program), the recipient automatically receives a license from the
  488. original licensor to copy, distribute or modify the Program subject to
  489. these terms and conditions. You may not impose any further
  490. restrictions on the recipients' exercise of the rights granted herein.
  491. You are not responsible for enforcing compliance by third parties to
  492. this License.
  493. 7. If, as a consequence of a court judgment or allegation of patent
  494. infringement or for any other reason (not limited to patent issues),
  495. conditions are imposed on you (whether by court order, agreement or
  496. otherwise) that contradict the conditions of this License, they do not
  497. excuse you from the conditions of this License. If you cannot
  498. distribute so as to satisfy simultaneously your obligations under this
  499. License and any other pertinent obligations, then as a consequence you
  500. may not distribute the Program at all. For example, if a patent
  501. license would not permit royalty-free redistribution of the Program by
  502. all those who receive copies directly or indirectly through you, then
  503. the only way you could satisfy both it and this License would be to
  504. refrain entirely from distribution of the Program.
  505. If any portion of this section is held invalid or unenforceable under
  506. any particular circumstance, the balance of the section is intended to
  507. apply and the section as a whole is intended to apply in other
  508. circumstances.
  509. It is not the purpose of this section to induce you to infringe any
  510. patents or other property right claims or to contest validity of any
  511. such claims; this section has the sole purpose of protecting the
  512. integrity of the free software distribution system, which is
  513. implemented by public license practices. Many people have made
  514. generous contributions to the wide range of software distributed
  515. through that system in reliance on consistent application of that
  516. system; it is up to the author/donor to decide if he or she is willing
  517. to distribute software through any other system and a licensee cannot
  518. impose that choice.
  519. This section is intended to make thoroughly clear what is believed to
  520. be a consequence of the rest of this License.
  521. 8. If the distribution and/or use of the Program is restricted in
  522. certain countries either by patents or by copyrighted interfaces, the
  523. original copyright holder who places the Program under this License
  524. may add an explicit geographical distribution limitation excluding
  525. those countries, so that distribution is permitted only in or among
  526. countries not thus excluded. In such case, this License incorporates
  527. the limitation as if written in the body of this License.
  528. 9. The Free Software Foundation may publish revised and/or new
  529. versions of the General Public License from time to time. Such new
  530. versions will be similar in spirit to the present version, but may
  531. differ in detail to address new problems or concerns.
  532. Each version is given a distinguishing version number. If the Program
  533. specifies a version number of this License which applies to it and
  534. "any later version", you have the option of following the terms and
  535. conditions either of that version or of any later version published by
  536. the Free Software Foundation. If the Program does not specify a
  537. version number of this License, you may choose any version ever
  538. published by the Free Software Foundation.
  539. 10. If you wish to incorporate parts of the Program into other free
  540. programs whose distribution conditions are different, write to the
  541. author to ask for permission. For software which is copyrighted by
  542. the Free Software Foundation, write to the Free Software Foundation;
  543. we sometimes make exceptions for this. Our decision will be guided by
  544. the two goals of preserving the free status of all derivatives of our
  545. free software and of promoting the sharing and reuse of software
  546. generally.
  547. NO WARRANTY
  548. 11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO
  549. WARRANTY FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW.
  550. EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR
  551. OTHER PARTIES PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY
  552. KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE
  553. IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR
  554. PURPOSE. THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE
  555. PROGRAM IS WITH YOU. SHOULD THE PROGRAM PROVE DEFECTIVE, YOU ASSUME
  556. THE COST OF ALL NECESSARY SERVICING, REPAIR OR CORRECTION.
  557. 12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN
  558. WRITING WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY
  559. AND/OR REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU
  560. FOR DAMAGES, INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR
  561. CONSEQUENTIAL DAMAGES ARISING OUT OF THE USE OR INABILITY TO USE THE
  562. PROGRAM (INCLUDING BUT NOT LIMITED TO LOSS OF DATA OR DATA BEING
  563. RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD PARTIES OR A
  564. FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER PROGRAMS), EVEN IF
  565. SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH
  566. DAMAGES.
  567. END OF TERMS AND CONDITIONS
  568. YOU ACKNOWLEDGE THAT YOU HAVE READ THIS AGREEMENT (INCLUDING THE
  569. EXHIBITS) AND UNDERSTAND IT, AND THAT BY CLICKING ON THE "ACCEPT"
  570. BUTTON BELOW AND INSTALLING/DOWNLOADING THE SOFTWARE YOU ACCEPT AND
  571. AGREE TO BE BOUND BY THE TERMS AND CONDITIONS OF THIS AGREEMENT.
