10 Version 3, 29 June 2007
13 Copyright © 2007 Free Software Foundation, Inc.
14 <ulink url="http://fsf.org/">http://fsf.org/</ulink>
17 Everyone is permitted to copy and distribute verbatim copies of this license
18 document, but changing it is not allowed.
20 <bridgehead id="gpl-3-preamble" renderas="sect1">
24 The <acronym>GNU</acronym> General Public License is a free, copyleft
25 license for software and other kinds of works.
28 The licenses for most software and other practical works are designed to
29 take away your freedom to share and change the works. By contrast, the
30 <acronym>GNU</acronym> General Public License is intended to guarantee your
31 freedom to share and change all versions of a program—to make sure it
32 remains free software for all its users. We, the Free Software Foundation,
33 use the <acronym>GNU</acronym> General Public License for most of our
34 software; it applies also to any other work released this way by its
35 authors. You can apply it to your programs, too.
38 When we speak of free software, we are referring to freedom, not price. Our
39 General Public Licenses are designed to make sure that you have the freedom
40 to distribute copies of free software (and charge for them if you wish),
41 that you receive source code or can get it if you want it, that you can
42 change the software or use pieces of it in new free programs, and that you
43 know you can do these things.
46 To protect your rights, we need to prevent others from denying you these
47 rights or asking you to surrender the rights. Therefore, you have certain
48 responsibilities if you distribute copies of the software, or if you modify
49 it: responsibilities to respect the freedom of others.
52 For example, if you distribute copies of such a program, whether gratis or
53 for a fee, you must pass on to the recipients the same freedoms that you
54 received. You must make sure that they, too, receive or can get the source
55 code. And you must show them these terms so they know their rights.
58 Developers that use the <acronym>GNU</acronym> <acronym>GPL</acronym>
59 protect your rights with two steps: (1) assert copyright on the software,
60 and (2) offer you this License giving you legal permission to copy,
61 distribute and/or modify it.
64 For the developers’ and authors’ protection, the
65 <acronym>GPL</acronym> clearly explains that there is no warranty for this
66 free software. For both users’ and authors’ sake, the
67 <acronym>GPL</acronym> requires that modified versions be marked as changed,
68 so that their problems will not be attributed erroneously to authors of
72 Some devices are designed to deny users access to install or run modified
73 versions of the software inside them, although the manufacturer can do so.
74 This is fundamentally incompatible with the aim of protecting users’
75 freedom to change the software. The systematic pattern of such abuse occurs
76 in the area of products for individuals to use, which is precisely where it
77 is most unacceptable. Therefore, we have designed this version of the
78 <acronym>GPL</acronym> to prohibit the practice for those products. If such
79 problems arise substantially in other domains, we stand ready to extend this
80 provision to those domains in future versions of the <acronym>GPL</acronym>,
81 as needed to protect the freedom of users.
84 Finally, every program is threatened constantly by software patents. States
85 should not allow patents to restrict development and use of software on
86 general-purpose computers, but in those that do, we wish to avoid the
87 special danger that patents applied to a free program could make it
88 effectively proprietary. To prevent this, the <acronym>GPL</acronym>
89 assures that patents cannot be used to render the program non-free.
92 The precise terms and conditions for copying, distribution and modification
98 <bridgehead id="gpl-3-definitions" renderas="sect1">
102 “This License” refers to version 3 of the <acronym>GNU</acronym>
103 General Public License.
106 “Copyright” also means copyright-like laws that apply to other
107 kinds of works, such as semiconductor masks.
110 “The Program” refers to any copyrightable work licensed under
111 this License. Each licensee is addressed as “you”.
112 “Licensees” and “recipients” may be individuals or
116 To “modify” a work means to copy from or adapt all or part of
117 the work in a fashion requiring copyright permission, other than the making
118 of an exact copy. The resulting work is called a “modified
119 version” of the earlier work or a work “based on” the
123 A “covered work” means either the unmodified Program or a work
124 based on the Program.
127 To “propagate” a work means to do anything with it that, without
128 permission, would make you directly or secondarily liable for infringement
129 under applicable copyright law, except executing it on a computer or
130 modifying a private copy. Propagation includes copying, distribution (with
131 or without modification), making available to the public, and in some
132 countries other activities as well.
135 To “convey” a work means any kind of propagation that enables
136 other parties to make or receive copies. Mere interaction with a user
137 through a computer network, with no transfer of a copy, is not conveying.
140 An interactive user interface displays “Appropriate Legal
141 Notices” to the extent that it includes a convenient and prominently
142 visible feature that (1) displays an appropriate copyright notice, and (2)
143 tells the user that there is no warranty for the work (except to the extent
144 that warranties are provided), that licensees may convey the work under this
145 License, and how to view a copy of this License. If the interface presents
146 a list of user commands or options, such as a menu, a prominent item in the
147 list meets this criterion.
149 <bridgehead id="SourceCode" renderas="sect1">
153 The “source code” for a work means the preferred form of the
154 work for making modifications to it. “Object code” means any
155 non-source form of a work.
158 A “Standard Interface” means an interface that either is an
159 official standard defined by a recognized standards body, or, in the case of
160 interfaces specified for a particular programming language, one that is
161 widely used among developers working in that language.
164 The “System Libraries” of an executable work include anything,
165 other than the work as a whole, that (a) is included in the normal form of
166 packaging a Major Component, but which is not part of that Major Component,
167 and (b) serves only to enable use of the work with that Major Component, or
168 to implement a Standard Interface for which an implementation is available
169 to the public in source code form. A “Major Component”, in this
170 context, means a major essential component (kernel, window system, and so
171 on) of the specific operating system (if any) on which the executable work
172 runs, or a compiler used to produce the work, or an object code interpreter
176 The “Corresponding Source” for a work in object code form means
177 all the source code needed to generate, install, and (for an executable
178 work) run the object code and to modify the work, including scripts to
179 control those activities. However, it does not include the work’s
180 System Libraries, or general-purpose tools or generally available free
181 programs which are used unmodified in performing those activities but which
182 are not part of the work. For example, Corresponding Source includes
183 interface definition files associated with source files for the work, and
184 the source code for shared libraries and dynamically linked subprograms that
185 the work is specifically designed to require, such as by intimate data
186 communication or control flow between those subprograms and other parts of
190 The Corresponding Source need not include anything that users can regenerate
191 automatically from other parts of the Corresponding Source.
194 The Corresponding Source for a work in source code form is that same work.
196 <bridgehead id="BasicPermissions" renderas="sect1">
197 2. Basic Permissions.
200 All rights granted under this License are granted for the term of copyright
201 on the Program, and are irrevocable provided the stated conditions are met.
202 This License explicitly affirms your unlimited permission to run the
203 unmodified Program. The output from running a covered work is covered by
204 this License only if the output, given its content, constitutes a covered
205 work. This License acknowledges your rights of fair use or other
206 equivalent, as provided by copyright law.
209 You may make, run and propagate covered works that you do not convey,
210 without conditions so long as your license otherwise remains in force. You
211 may convey covered works to others for the sole purpose of having them make
212 modifications exclusively for you, or provide you with facilities for
213 running those works, provided that you comply with the terms of this License
214 in conveying all material for which you do not control copyright. Those
215 thus making or running the covered works for you must do so exclusively on
216 your behalf, under your direction and control, on terms that prohibit them
217 from making any copies of your copyrighted material outside their
218 relationship with you.
221 Conveying under any other circumstances is permitted solely under the
222 conditions stated below. Sublicensing is not allowed; section 10 makes it
225 <bridgehead id="Protecting" renderas="sect1">
226 3. Protecting Users’ Legal Rights From Anti-Circumvention Law.
229 No covered work shall be deemed part of an effective technological measure
230 under any applicable law fulfilling obligations under article 11 of the WIPO
231 copyright treaty adopted on 20 December 1996, or similar laws prohibiting or
232 restricting circumvention of such measures.
235 When you convey a covered work, you waive any legal power to forbid
236 circumvention of technological measures to the extent such circumvention is
237 effected by exercising rights under this License with respect to the covered
238 work, and you disclaim any intention to limit operation or modification of
239 the work as a means of enforcing, against the work’s users, your or
240 third parties’ legal rights to forbid circumvention of technological
243 <bridgehead id="ConveyingVerbatim" renderas="sect1">
244 4. Conveying Verbatim Copies.
247 You may convey verbatim copies of the Program’s source code as you
248 receive it, in any medium, provided that you conspicuously and appropriately
249 publish on each copy an appropriate copyright notice; keep intact all
250 notices stating that this License and any non-permissive terms added in
251 accord with section 7 apply to the code; keep intact all notices of the
252 absence of any warranty; and give all recipients a copy of this License
253 along with the Program.
256 You may charge any price or no price for each copy that you convey, and you
257 may offer support or warranty protection for a fee.
259 <bridgehead id="ConveyingModified" renderas="sect1">
260 5. Conveying Modified Source Versions.
263 You may convey a work based on the Program, or the modifications to produce
264 it from the Program, in the form of source code under the terms of section
265 4, provided that you also meet all of these conditions:
267 <orderedlist numeration="loweralpha">
270 The work must carry prominent notices stating that you modified it, and
271 giving a relevant date.
276 The work must carry prominent notices stating that it is released under
277 this License and any conditions added under section 7. This requirement
278 modifies the requirement in section 4 to “keep intact all
284 You must license the entire work, as a whole, under this License to
285 anyone who comes into possession of a copy. This License will therefore
286 apply, along with any applicable section 7 additional terms, to the
287 whole of the work, and all its parts, regardless of how they are
288 packaged. This License gives no permission to license the work in any
289 other way, but it does not invalidate such permission if you have
290 separately received it.
295 If the work has interactive user interfaces, each must display
296 Appropriate Legal Notices; however, if the Program has interactive
297 interfaces that do not display Appropriate Legal Notices, your work need
303 A compilation of a covered work with other separate and independent works,
304 which are not by their nature extensions of the covered work, and which are
305 not combined with it such as to form a larger program, in or on a volume of
306 a storage or distribution medium, is called an “aggregate” if
307 the compilation and its resulting copyright are not used to limit the access
308 or legal rights of the compilation’s users beyond what the individual works
309 permit. Inclusion of a covered work in an aggregate does not cause
310 this License to apply to the other parts of the aggregate.
312 <bridgehead id="ConveyingNonSource" renderas="sect1">
313 6. Conveying Non-Source Forms.
316 You may convey a covered work in object code form under the terms of
317 sections 4 and 5, provided that you also convey the machine-readable
318 Corresponding Source under the terms of this License, in one of these ways:
320 <orderedlist numeration="loweralpha">
323 Convey the object code in, or embodied in, a physical product (including
324 a physical distribution medium), accompanied by the Corresponding Source
325 fixed on a durable physical medium customarily used for software
331 Convey the object code in, or embodied in, a physical product (including
332 a physical distribution medium), accompanied by a written offer, valid
333 for at least three years and valid for as long as you offer spare parts
334 or customer support for that product model, to give anyone who possesses
335 the object code either (1) a copy of the Corresponding Source for all
336 the software in the product that is covered by this License, on a
337 durable physical medium customarily used for software interchange, for a
338 price no more than your reasonable cost of physically performing this
339 conveying of source, or (2) access to copy the Corresponding Source from
340 a network server at no charge.
345 Convey individual copies of the object code with a copy of the written
346 offer to provide the Corresponding Source. This alternative is allowed
347 only occasionally and noncommercially, and only if you received the
348 object code with such an offer, in accord with subsection 6b.
353 Convey the object code by offering access from a designated place
354 (gratis or for a charge), and offer equivalent access to the
355 Corresponding Source in the same way through the same place at no
356 further charge. You need not require recipients to copy the
357 Corresponding Source along with the object code. If the place to copy
358 the object code is a network server, the Corresponding Source may be on
359 a different server (operated by you or a third party) that supports
360 equivalent copying facilities, provided you maintain clear directions
361 next to the object code saying where to find the Corresponding Source.
362 Regardless of what server hosts the Corresponding Source, you remain
363 obligated to ensure that it is available for as long as needed to
364 satisfy these requirements.
369 Convey the object code using peer-to-peer transmission, provided you
370 inform other peers where the object code and Corresponding Source of the
371 work are being offered to the general public at no charge under
377 A separable portion of the object code, whose source code is excluded from
378 the Corresponding Source as a System Library, need not be included in
379 conveying the object code work.
382 A “User Product” is either (1) a “consumer product”,
383 which means any tangible personal property which is normally used for
384 personal, family, or household purposes, or (2) anything designed or sold
385 for incorporation into a dwelling. In determining whether a product is a
386 consumer product, doubtful cases shall be resolved in favor of coverage.
387 For a particular product received by a particular user, “normally
388 used” refers to a typical or common use of that class of product,
389 regardless of the status of the particular user or of the way in which the
390 particular user actually uses, or expects or is expected to use, the
391 product. A product is a consumer product regardless of whether the product
392 has substantial commercial, industrial or non-consumer uses, unless such
393 uses represent the only significant mode of use of the product.
396 “Installation Information” for a User Product means any methods,
397 procedures, authorization keys, or other information required to install and
398 execute modified versions of a covered work in that User Product from a
399 modified version of its Corresponding Source. The information must suffice
400 to ensure that the continued functioning of the modified object code is in
401 no case prevented or interfered with solely because modification has been
405 If you convey an object code work under this section in, or with, or
406 specifically for use in, a User Product, and the conveying occurs as part of
407 a transaction in which the right of possession and use of the User Product
408 is transferred to the recipient in perpetuity or for a fixed term
409 (regardless of how the transaction is characterized), the Corresponding
410 Source conveyed under this section must be accompanied by the Installation
411 Information. But this requirement does not apply if neither you nor any
412 third party retains the ability to install modified object code on the User
413 Product (for example, the work has been installed in
414 <acronym>ROM</acronym>).
417 The requirement to provide Installation Information does not include a
418 requirement to continue to provide support service, warranty, or updates for
419 a work that has been modified or installed by the recipient, or for the User
420 Product in which it has been modified or installed. Access to a network may
421 be denied when the modification itself materially and adversely affects the
422 operation of the network or violates the rules and protocols for
423 communication across the network.
426 Corresponding Source conveyed, and Installation Information provided, in
427 accord with this section must be in a format that is publicly documented
428 (and with an implementation available to the public in source code form),
429 and must require no special password or key for unpacking, reading or
432 <bridgehead id="AdditionalTerms" renderas="sect1">
436 “Additional permissions” are terms that supplement the terms of
437 this License by making exceptions from one or more of its conditions.
438 Additional permissions that are applicable to the entire Program shall be
439 treated as though they were included in this License, to the extent that
440 they are valid under applicable law. If additional permissions apply only
441 to part of the Program, that part may be used separately under those
442 permissions, but the entire Program remains governed by this License
443 without regard to the additional permissions.
446 When you convey a copy of a covered work, you may at your option remove any
447 additional permissions from that copy, or from any part of it. (Additional
448 permissions may be written to require their own removal in certain cases
449 when you modify the work.) You may place additional permissions on
450 material, added by you to a covered work, for which you have or can give
451 appropriate copyright permission.
454 Notwithstanding any other provision of this License, for material you add
455 to a covered work, you may (if authorized by the copyright holders of that
456 material) supplement the terms of this License with terms:
458 <orderedlist numeration="loweralpha">
461 Disclaiming warranty or limiting liability differently from the terms
462 of sections 15 and 16 of this License; or
467 Requiring preservation of specified reasonable legal notices or author
468 attributions in that material or in the Appropriate Legal Notices
469 displayed by works containing it; or
474 Prohibiting misrepresentation of the origin of that material, or
475 requiring that modified versions of such material be marked in
476 reasonable ways as different from the original version; or
481 Limiting the use for publicity purposes of names of licensors or
482 authors of the material; or
487 Declining to grant rights under trademark law for use of some trade
488 names, trademarks, or service marks; or
493 Requiring indemnification of licensors and authors of that material by
494 anyone who conveys the material (or modified versions of it) with
495 contractual assumptions of liability to the recipient, for any
496 liability that these contractual assumptions directly impose on those
497 licensors and authors.
502 All other non-permissive additional terms are considered “further
503 restrictions” within the meaning of section 10. If the Program as
504 you received it, or any part of it, contains a notice stating that it is
505 governed by this License along with a term that is a further restriction,
506 you may remove that term. If a license document contains a further
507 restriction but permits relicensing or conveying under this License, you
508 may add to a covered work material governed by the terms of that license
509 document, provided that the further restriction does not survive such
510 relicensing or conveying.
513 If you add terms to a covered work in accord with this section, you must
514 place, in the relevant source files, a statement of the additional terms
515 that apply to those files, or a notice indicating where to find the
519 Additional terms, permissive or non-permissive, may be stated in the form
520 of a separately written license, or stated as exceptions; the above
521 requirements apply either way.
523 <bridgehead id="gpl-3-termination" renderas="sect1">
527 You may not propagate or modify a covered work except as expressly provided
528 under this License. Any attempt otherwise to propagate or modify it is
529 void, and will automatically terminate your rights under this License
530 (including any patent licenses granted under the third paragraph of section
534 However, if you cease all violation of this License, then your license from
535 a particular copyright holder is reinstated (a) provisionally, unless and
536 until the copyright holder explicitly and finally terminates your license,
537 and (b) permanently, if the copyright holder fails to notify you of the
538 violation by some reasonable means prior to 60 days after the cessation.
541 Moreover, your license from a particular copyright holder is reinstated
542 permanently if the copyright holder notifies you of the violation by some
543 reasonable means, this is the first time you have received notice of
544 violation of this License (for any work) from that copyright holder, and
545 you cure the violation prior to 30 days after your receipt of the notice.
548 Termination of your rights under this section does not terminate the
549 licenses of parties who have received copies or rights from you under this
550 License. If your rights have been terminated and not permanently
551 reinstated, you do not qualify to receive new licenses for the same
552 material under section 10.
554 <bridgehead id="AcceptanceNotRequired" renderas="sect1">
555 9. Acceptance Not Required for Having Copies.
558 You are not required to accept this License in order to receive or run a
559 copy of the Program. Ancillary propagation of a covered work occurring
560 solely as a consequence of using peer-to-peer transmission to receive a
561 copy likewise does not require acceptance. However, nothing other than
562 this License grants you permission to propagate or modify any covered work.
563 These actions infringe copyright if you do not accept this License.
564 Therefore, by modifying or propagating a covered work, you indicate your
565 acceptance of this License to do so.
567 <bridgehead id="AutomaticDownstream" renderas="sect1">
568 10. Automatic Licensing of Downstream Recipients.
571 Each time you convey a covered work, the recipient automatically receives a
572 license from the original licensors, to run, modify and propagate that
573 work, subject to this License. You are not responsible for enforcing
574 compliance by third parties with this License.
577 An “entity transaction” is a transaction transferring control
578 of an organization, or substantially all assets of one, or subdividing an
579 organization, or merging organizations. If propagation of a covered work
580 results from an entity transaction, each party to that transaction who
581 receives a copy of the work also receives whatever licenses to the work the
582 party’s predecessor in interest had or could give under the previous
583 paragraph, plus a right to possession of the Corresponding Source of the
584 work from the predecessor in interest, if the predecessor has it or can get
585 it with reasonable efforts.
588 You may not impose any further restrictions on the exercise of the rights
589 granted or affirmed under this License. For example, you may not impose a
590 license fee, royalty, or other charge for exercise of rights granted under
591 this License, and you may not initiate litigation (including a cross-claim
592 or counterclaim in a lawsuit) alleging that any patent claim is infringed
593 by making, using, selling, offering for sale, or importing the Program or
596 <bridgehead id="Patents" renderas="sect1">
600 A “contributor” is a copyright holder who authorizes use under
601 this License of the Program or a work on which the Program is based. The
602 work thus licensed is called the contributor’s “contributor
606 A contributor’s “essential patent claims” are all patent
607 claims owned or controlled by the contributor, whether already acquired or
608 hereafter acquired, that would be infringed by some manner, permitted by
609 this License, of making, using, or selling its contributor version, but do
610 not include claims that would be infringed only as a consequence of further
611 modification of the contributor version. For purposes of this definition,
612 “control” includes the right to grant patent sublicenses in a
613 manner consistent with the requirements of this License.
616 Each contributor grants you a non-exclusive, worldwide, royalty-free patent
617 license under the contributor’s essential patent claims, to make, use,
618 sell, offer for sale, import and otherwise run, modify and propagate the
619 contents of its contributor version.
622 In the following three paragraphs, a “patent license” is any
623 express agreement or commitment, however denominated, not to enforce a
624 patent (such as an express permission to practice a patent or covenant not
625 to sue for patent infringement). To “grant” such a patent
626 license to a party means to make such an agreement or commitment not to
627 enforce a patent against the party.
630 If you convey a covered work, knowingly relying on a patent license, and the
631 Corresponding Source of the work is not available for anyone to copy, free
632 of charge and under the terms of this License, through a publicly available
633 network server or other readily accessible means, then you must either (1)
634 cause the Corresponding Source to be so available, or (2) arrange to deprive
635 yourself of the benefit of the patent license for this particular work, or
636 (3) arrange, in a manner consistent with the requirements of this License,
637 to extend the patent license to downstream recipients. “Knowingly
638 relying” means you have actual knowledge that, but for the patent
639 license, your conveying the covered work in a country, or your
640 recipient’s use of the covered work in a country, would infringe one
641 or more identifiable patents in that country that you have reason to believe
645 If, pursuant to or in connection with a single transaction or arrangement,
646 you convey, or propagate by procuring conveyance of, a covered work, and
647 grant a patent license to some of the parties receiving the covered work
648 authorizing them to use, propagate, modify or convey a specific copy of the
649 covered work, then the patent license you grant is automatically extended to
650 all recipients of the covered work and works based on it.
653 A patent license is “discriminatory” if it does not include
654 within the scope of its coverage, prohibits the exercise of, or is
655 conditioned on the non-exercise of one or more of the rights that are
656 specifically granted under this License. You may not convey a covered work
657 if you are a party to an arrangement with a third party that is in the
658 business of distributing software, under which you make payment to the third
659 party based on the extent of your activity of conveying the work, and under
660 which the third party grants, to any of the parties who would receive the
661 covered work from you, a discriminatory patent license (a) in connection
662 with copies of the covered work conveyed by you (or copies made from those
663 copies), or (b) primarily for and in connection with specific products or
664 compilations that contain the covered work, unless you entered into that
665 arrangement, or that patent license was granted, prior to 28 March 2007.
668 Nothing in this License shall be construed as excluding or limiting any

676 If conditions are imposed on you (whether by court order, agreement or
677 otherwise) that contradict the conditions of this License, they do not
678 excuse you from the conditions of this License. If you cannot convey a
679 covered work so as to satisfy simultaneously your obligations under this
680 License and any other pertinent obligations, then as a consequence you may
681 not convey it at all. For example, if you agree to terms that obligate you
682 to collect a royalty for further conveying from those to whom you convey the
683 Program, the only way you could satisfy both those terms and this License
684 would be to refrain entirely from conveying the Program.

703 The Free Software Foundation may publish revised and/or new versions of the
704 <acronym>GNU</acronym> General Public License from time to time. Such new
705 versions will be similar in spirit to the present version, but may differ in
706 detail to address new problems or concerns.
709 Each version is given a distinguishing version number. If the Program
710 specifies that a certain numbered version of the <acronym>GNU</acronym>
711 General Public License “or any later version” applies to it, you
712 have the option of following the terms and conditions either of that
713 numbered version or of any later version published by the Free Software
714 Foundation. If the Program does not specify a version number of the
715 <acronym>GNU</acronym> General Public License, you may choose any version
716 ever published by the Free Software Foundation.
719 If the Program specifies that a proxy can decide which future versions of
720 the <acronym>GNU</acronym> General Public License can be used, that
721 proxy’s public statement of acceptance of a version permanently
722 authorizes you to choose that version for the Program.
725 Later license versions may give you additional or different permissions.
726 However, no additional obligations are imposed on any author or copyright

771 How to Apply These Terms to Your New Programs
774 If you develop a new program, and you want it to be of the greatest possible
775 use to the public, the best way to achieve this is to make it free software
776 which everyone can redistribute and change under these terms.
779 To do so, attach the following notices to the program. It is safest to
780 attach them to the start of each source file to most effectively state the
781 exclusion of warranty; and each file should have at least the
782 “copyright” line and a pointer to where the full notice is
786 <replaceable>one line to give the program’s name and a brief idea of what it does.</replaceable>
787 Copyright (C) <replaceable>year</replaceable> <replaceable>name of author</replaceable>
789 This program is free software: you can redistribute it and/or modify
790 it under the terms of the <acronym>GNU</acronym> General Public License as published by
791 the Free Software Foundation, either version 3 of the License, or
792 (at your option) any later version.
794 This program is distributed in the hope that it will be useful,
795 but WITHOUT ANY WARRANTY; without even the implied warranty of
796 MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the
797 <acronym>GNU</acronym> General Public License for more details.
799 You should have received a copy of the <acronym>GNU</acronym> General Public License
800 along with this program. If not, see <ulink url="http://www.gnu.org/licenses/">http://www.gnu.org/licenses/</ulink>.
803 Also add information on how to contact you by electronic and paper mail.
806 If the program does terminal interaction, make it output a short notice like
807 this when it starts in an interactive mode:
810 <replaceable>program</replaceable> Copyright (C) <replaceable>year</replaceable> <replaceable>name of author</replaceable>
811 This program comes with ABSOLUTELY NO WARRANTY; for details type ‘<literal>show w</literal>’.
812 This is free software, and you are welcome to redistribute it
813 under certain conditions; type ‘<literal>show c</literal>’ for details.
816 The hypothetical commands ‘<literal>show w</literal>’ and
817 ‘<literal>show c</literal>’ should show the appropriate parts of
818 the General Public License. Of course, your program’s commands might be
819 different; for a GUI interface, you would use an “about box”.
822 You should also get your employer (if you work as a programmer) or school,
823 if any, to sign a “copyright disclaimer” for the program, if
824 necessary. For more information on this, and how to apply and follow the
825 <acronym>GNU</acronym> <acronym>GPL</acronym>, see
826 <ulink url="http://www.gnu.org/licenses/">http://www.gnu.org/licenses/</ulink>.
829 The <acronym>GNU</acronym> General Public License does not permit
830 incorporating your program into proprietary programs. If your program is a
831 subroutine library, you may consider it more useful to permit linking
832 proprietary applications with the library. If this is what you want to do,
833 use the <acronym>GNU</acronym> Lesser General Public License instead of this
834 License. But first, please read <ulink
