- </h2></div></div></div><p>
- Version 3, 29 June 2007
- </p><p>
- Copyright © 2007 Free Software Foundation, Inc.
- <a class="ulink" href="http://fsf.org/" target="_top">http://fsf.org/</a>
- </p><p>
- Everyone is permitted to copy and distribute verbatim copies of this license
- document, but changing it is not allowed.
- </p><h2><a id="gpl-3-preamble"></a>
- Preamble
- </h2><p>
- The <acronym class="acronym">GNU</acronym> General Public License is a free, copyleft
- license for software and other kinds of works.
- </p><p>
- The licenses for most software and other practical works are designed to
- take away your freedom to share and change the works. By contrast, the
- <acronym class="acronym">GNU</acronym> General Public License is intended to guarantee your
- freedom to share and change all versions of a program—to make sure it
- remains free software for all its users. We, the Free Software Foundation,
- use the <acronym class="acronym">GNU</acronym> General Public License for most of our
- software; it applies also to any other work released this way by its
- authors. You can apply it to your programs, too.
- </p><p>
- When we speak of free software, we are referring to freedom, not price. Our
- General Public Licenses are designed to make sure that you have the freedom
- to distribute copies of free software (and charge for them if you wish),
- that you receive source code or can get it if you want it, that you can
- change the software or use pieces of it in new free programs, and that you
- know you can do these things.
- </p><p>
- To protect your rights, we need to prevent others from denying you these
- rights or asking you to surrender the rights. Therefore, you have certain
- responsibilities if you distribute copies of the software, or if you modify
- it: responsibilities to respect the freedom of others.
- </p><p>
- For example, if you distribute copies of such a program, whether gratis or
- for a fee, you must pass on to the recipients the same freedoms that you
- received. You must make sure that they, too, receive or can get the source
- code. And you must show them these terms so they know their rights.
- </p><p>
- Developers that use the <acronym class="acronym">GNU</acronym> <acronym class="acronym">GPL</acronym>
- protect your rights with two steps: (1) assert copyright on the software,
- and (2) offer you this License giving you legal permission to copy,
- distribute and/or modify it.
- </p><p>
- For the developers’ and authors’ protection, the
- <acronym class="acronym">GPL</acronym> clearly explains that there is no warranty for this
- free software. For both users’ and authors’ sake, the
- <acronym class="acronym">GPL</acronym> requires that modified versions be marked as changed,
- so that their problems will not be attributed erroneously to authors of
- previous versions.
- </p><p>
- Some devices are designed to deny users access to install or run modified
- versions of the software inside them, although the manufacturer can do so.
- This is fundamentally incompatible with the aim of protecting users’
- freedom to change the software. The systematic pattern of such abuse occurs
- in the area of products for individuals to use, which is precisely where it
- is most unacceptable. Therefore, we have designed this version of the
- <acronym class="acronym">GPL</acronym> to prohibit the practice for those products. If such
- problems arise substantially in other domains, we stand ready to extend this
- provision to those domains in future versions of the <acronym class="acronym">GPL</acronym>,
- as needed to protect the freedom of users.
- </p><p>
- Finally, every program is threatened constantly by software patents. States
- should not allow patents to restrict development and use of software on
- general-purpose computers, but in those that do, we wish to avoid the
- special danger that patents applied to a free program could make it
- effectively proprietary. To prevent this, the <acronym class="acronym">GPL</acronym>
- assures that patents cannot be used to render the program non-free.
- </p><p>
- The precise terms and conditions for copying, distribution and modification
- follow.
- </p><h2><a id="id518323"></a>
- TERMS AND CONDITIONS
- </h2><h2><a id="gpl-3-definitions"></a>
- 0. Definitions.
- </h2><p>
- “This License” refers to version 3 of the <acronym class="acronym">GNU</acronym>
- General Public License.
- </p><p>
- “Copyright” also means copyright-like laws that apply to other
- kinds of works, such as semiconductor masks.
- </p><p>
- “The Program” refers to any copyrightable work licensed under
- this License. Each licensee is addressed as “you”.
- “Licensees” and “recipients” may be individuals or
- organizations.
- </p><p>
- To “modify” a work means to copy from or adapt all or part of
- the work in a fashion requiring copyright permission, other than the making
- of an exact copy. The resulting work is called a “modified
- version” of the earlier work or a work “based on” the
- earlier work.
- </p><p>
- A “covered work” means either the unmodified Program or a work
- based on the Program.
- </p><p>
- To “propagate” a work means to do anything with it that, without
- permission, would make you directly or secondarily liable for infringement
- under applicable copyright law, except executing it on a computer or
- modifying a private copy. Propagation includes copying, distribution (with
- or without modification), making available to the public, and in some
- countries other activities as well.
- </p><p>
- To “convey” a work means any kind of propagation that enables
- other parties to make or receive copies. Mere interaction with a user
- through a computer network, with no transfer of a copy, is not conveying.
- </p><p>
- An interactive user interface displays “Appropriate Legal
- Notices” to the extent that it includes a convenient and prominently
- visible feature that (1) displays an appropriate copyright notice, and (2)
- tells the user that there is no warranty for the work (except to the extent
- that warranties are provided), that licensees may convey the work under this
- License, and how to view a copy of this License. If the interface presents
- a list of user commands or options, such as a menu, a prominent item in the
- list meets this criterion.
- </p><h2><a id="SourceCode"></a>
- 1. Source Code.
- </h2><p>
- The “source code” for a work means the preferred form of the
- work for making modifications to it. “Object code” means any
- non-source form of a work.
- </p><p>
- A “Standard Interface” means an interface that either is an
- official standard defined by a recognized standards body, or, in the case of
- interfaces specified for a particular programming language, one that is
- widely used among developers working in that language.
- </p><p>
- The “System Libraries” of an executable work include anything,
- other than the work as a whole, that (a) is included in the normal form of
- packaging a Major Component, but which is not part of that Major Component,
- and (b) serves only to enable use of the work with that Major Component, or
- to implement a Standard Interface for which an implementation is available
- to the public in source code form. A “Major Component”, in this
- context, means a major essential component (kernel, window system, and so
- on) of the specific operating system (if any) on which the executable work
- runs, or a compiler used to produce the work, or an object code interpreter
- used to run it.
- </p><p>
- The “Corresponding Source” for a work in object code form means
- all the source code needed to generate, install, and (for an executable
- work) run the object code and to modify the work, including scripts to
- control those activities. However, it does not include the work’s
- System Libraries, or general-purpose tools or generally available free
- programs which are used unmodified in performing those activities but which
- are not part of the work. For example, Corresponding Source includes
- interface definition files associated with source files for the work, and
- the source code for shared libraries and dynamically linked subprograms that
- the work is specifically designed to require, such as by intimate data
- communication or control flow between those subprograms and other parts of
- the work.
- </p><p>
- The Corresponding Source need not include anything that users can regenerate
- automatically from other parts of the Corresponding Source.
- </p><p>
- The Corresponding Source for a work in source code form is that same work.
- </p><h2><a id="BasicPermissions"></a>
- 2. Basic Permissions.
- </h2><p>
- All rights granted under this License are granted for the term of copyright
- on the Program, and are irrevocable provided the stated conditions are met.
- This License explicitly affirms your unlimited permission to run the
- unmodified Program. The output from running a covered work is covered by
- this License only if the output, given its content, constitutes a covered
- work. This License acknowledges your rights of fair use or other
- equivalent, as provided by copyright law.
- </p><p>
- You may make, run and propagate covered works that you do not convey,
- without conditions so long as your license otherwise remains in force. You
- may convey covered works to others for the sole purpose of having them make
- modifications exclusively for you, or provide you with facilities for
- running those works, provided that you comply with the terms of this License
- in conveying all material for which you do not control copyright. Those
- thus making or running the covered works for you must do so exclusively on
- your behalf, under your direction and control, on terms that prohibit them
- from making any copies of your copyrighted material outside their
- relationship with you.
- </p><p>
- Conveying under any other circumstances is permitted solely under the
- conditions stated below. Sublicensing is not allowed; section 10 makes it
- unnecessary.
- </p><h2><a id="Protecting"></a>
- 3. Protecting Users’ Legal Rights From Anti-Circumvention Law.
- </h2><p>
- No covered work shall be deemed part of an effective technological measure
- under any applicable law fulfilling obligations under article 11 of the WIPO
- copyright treaty adopted on 20 December 1996, or similar laws prohibiting or
- restricting circumvention of such measures.
- </p><p>
- When you convey a covered work, you waive any legal power to forbid
- circumvention of technological measures to the extent such circumvention is
- effected by exercising rights under this License with respect to the covered
- work, and you disclaim any intention to limit operation or modification of
- the work as a means of enforcing, against the work’s users, your or
- third parties’ legal rights to forbid circumvention of technological
- measures.
- </p><h2><a id="ConveyingVerbatim"></a>
- 4. Conveying Verbatim Copies.
- </h2><p>
- You may convey verbatim copies of the Program’s source code as you
- receive it, in any medium, provided that you conspicuously and appropriately
- publish on each copy an appropriate copyright notice; keep intact all
- notices stating that this License and any non-permissive terms added in
- accord with section 7 apply to the code; keep intact all notices of the
- absence of any warranty; and give all recipients a copy of this License
- along with the Program.
- </p><p>
- You may charge any price or no price for each copy that you convey, and you
- may offer support or warranty protection for a fee.
- </p><h2><a id="ConveyingModified"></a>
- 5. Conveying Modified Source Versions.
- </h2><p>
- You may convey a work based on the Program, or the modifications to produce
- it from the Program, in the form of source code under the terms of section
- 4, provided that you also meet all of these conditions:
- </p><div class="orderedlist"><ol type="a"><li><p>
- The work must carry prominent notices stating that you modified it, and
- giving a relevant date.
- </p></li><li><p>
- The work must carry prominent notices stating that it is released under
- this License and any conditions added under section 7. This requirement
- modifies the requirement in section 4 to “keep intact all
- notices”.
- </p></li><li><p>
- You must license the entire work, as a whole, under this License to
- anyone who comes into possession of a copy. This License will therefore
- apply, along with any applicable section 7 additional terms, to the
- whole of the work, and all its parts, regardless of how they are
- packaged. This License gives no permission to license the work in any
- other way, but it does not invalidate such permission if you have
- separately received it.
- </p></li><li><p>
- If the work has interactive user interfaces, each must display
- Appropriate Legal Notices; however, if the Program has interactive
- interfaces that do not display Appropriate Legal Notices, your work need
- not make them do so.
- </p></li></ol></div><p>
- A compilation of a covered work with other separate and independent works,
- which are not by their nature extensions of the covered work, and which are
- not combined with it such as to form a larger program, in or on a volume of
- a storage or distribution medium, is called an “aggregate” if
- the compilation and its resulting copyright are not used to limit the access
- or legal rights of the compilation’s users beyond what the individual works
- permit. Inclusion of a covered work in an aggregate does not cause
- this License to apply to the other parts of the aggregate.
- </p><h2><a id="ConveyingNonSource"></a>
- 6. Conveying Non-Source Forms.
- </h2><p>
- You may convey a covered work in object code form under the terms of
- sections 4 and 5, provided that you also convey the machine-readable
- Corresponding Source under the terms of this License, in one of these ways:
- </p><div class="orderedlist"><ol type="a"><li><p>
- Convey the object code in, or embodied in, a physical product (including
- a physical distribution medium), accompanied by the Corresponding Source
- fixed on a durable physical medium customarily used for software
- interchange.
- </p></li><li><p>
- Convey the object code in, or embodied in, a physical product (including
- a physical distribution medium), accompanied by a written offer, valid
- for at least three years and valid for as long as you offer spare parts
- or customer support for that product model, to give anyone who possesses
- the object code either (1) a copy of the Corresponding Source for all
- the software in the product that is covered by this License, on a
- durable physical medium customarily used for software interchange, for a
- price no more than your reasonable cost of physically performing this
- conveying of source, or (2) access to copy the Corresponding Source from
- a network server at no charge.
- </p></li><li><p>
- Convey individual copies of the object code with a copy of the written
- offer to provide the Corresponding Source. This alternative is allowed
- only occasionally and noncommercially, and only if you received the
- object code with such an offer, in accord with subsection 6b.
- </p></li><li><p>
- Convey the object code by offering access from a designated place
- (gratis or for a charge), and offer equivalent access to the
- Corresponding Source in the same way through the same place at no
- further charge. You need not require recipients to copy the
- Corresponding Source along with the object code. If the place to copy
- the object code is a network server, the Corresponding Source may be on
- a different server (operated by you or a third party) that supports
- equivalent copying facilities, provided you maintain clear directions
- next to the object code saying where to find the Corresponding Source.
- Regardless of what server hosts the Corresponding Source, you remain
- obligated to ensure that it is available for as long as needed to
- satisfy these requirements.
- </p></li><li><p>
- Convey the object code using peer-to-peer transmission, provided you
- inform other peers where the object code and Corresponding Source of the
- work are being offered to the general public at no charge under
- subsection 6d.
- </p></li></ol></div><p>
- A separable portion of the object code, whose source code is excluded from
- the Corresponding Source as a System Library, need not be included in
- conveying the object code work.
- </p><p>
- A “User Product” is either (1) a “consumer product”,
- which means any tangible personal property which is normally used for
- personal, family, or household purposes, or (2) anything designed or sold
- for incorporation into a dwelling. In determining whether a product is a
- consumer product, doubtful cases shall be resolved in favor of coverage.
- For a particular product received by a particular user, “normally
- used” refers to a typical or common use of that class of product,
- regardless of the status of the particular user or of the way in which the
- particular user actually uses, or expects or is expected to use, the
- product. A product is a consumer product regardless of whether the product
- has substantial commercial, industrial or non-consumer uses, unless such
- uses represent the only significant mode of use of the product.
- </p><p>
- “Installation Information” for a User Product means any methods,
- procedures, authorization keys, or other information required to install and
- execute modified versions of a covered work in that User Product from a
- modified version of its Corresponding Source. The information must suffice
- to ensure that the continued functioning of the modified object code is in
- no case prevented or interfered with solely because modification has been
- made.
- </p><p>
- If you convey an object code work under this section in, or with, or
- specifically for use in, a User Product, and the conveying occurs as part of
- a transaction in which the right of possession and use of the User Product
- is transferred to the recipient in perpetuity or for a fixed term
- (regardless of how the transaction is characterized), the Corresponding
- Source conveyed under this section must be accompanied by the Installation
- Information. But this requirement does not apply if neither you nor any
- third party retains the ability to install modified object code on the User
- Product (for example, the work has been installed in
- <acronym class="acronym">ROM</acronym>).
- </p><p>
- The requirement to provide Installation Information does not include a
- requirement to continue to provide support service, warranty, or updates for
- a work that has been modified or installed by the recipient, or for the User
- Product in which it has been modified or installed. Access to a network may
- be denied when the modification itself materially and adversely affects the
- operation of the network or violates the rules and protocols for
- communication across the network.
- </p><p>
- Corresponding Source conveyed, and Installation Information provided, in
- accord with this section must be in a format that is publicly documented
- (and with an implementation available to the public in source code form),
- and must require no special password or key for unpacking, reading or
- copying.
- </p><h2><a id="AdditionalTerms"></a>
- 7. Additional Terms.
- </h2><p>
- “Additional permissions” are terms that supplement the terms of
- this License by making exceptions from one or more of its conditions.
- Additional permissions that are applicable to the entire Program shall be
- treated as though they were included in this License, to the extent that
- they are valid under applicable law. If additional permissions apply only
- to part of the Program, that part may be used separately under those
- permissions, but the entire Program remains governed by this License
- without regard to the additional permissions.
- </p><p>
- When you convey a copy of a covered work, you may at your option remove any
- additional permissions from that copy, or from any part of it. (Additional
- permissions may be written to require their own removal in certain cases
- when you modify the work.) You may place additional permissions on
- material, added by you to a covered work, for which you have or can give
- appropriate copyright permission.
- </p><p>
- Notwithstanding any other provision of this License, for material you add
- to a covered work, you may (if authorized by the copyright holders of that
- material) supplement the terms of this License with terms:
- </p><div class="orderedlist"><ol type="a"><li><p>
- Disclaiming warranty or limiting liability differently from the terms
- of sections 15 and 16 of this License; or
- </p></li><li><p>
- Requiring preservation of specified reasonable legal notices or author
- attributions in that material or in the Appropriate Legal Notices
- displayed by works containing it; or
- </p></li><li><p>
- Prohibiting misrepresentation of the origin of that material, or
- requiring that modified versions of such material be marked in
- reasonable ways as different from the original version; or
- </p></li><li><p>
- Limiting the use for publicity purposes of names of licensors or
- authors of the material; or
- </p></li><li><p>
- Declining to grant rights under trademark law for use of some trade
- names, trademarks, or service marks; or
- </p></li><li><p>
- Requiring indemnification of licensors and authors of that material by
- anyone who conveys the material (or modified versions of it) with
- contractual assumptions of liability to the recipient, for any
- liability that these contractual assumptions directly impose on those
- licensors and authors.
- </p></li></ol></div><p>
- All other non-permissive additional terms are considered “further
- restrictions” within the meaning of section 10. If the Program as
- you received it, or any part of it, contains a notice stating that it is
- governed by this License along with a term that is a further restriction,
- you may remove that term. If a license document contains a further
- restriction but permits relicensing or conveying under this License, you
- may add to a covered work material governed by the terms of that license
- document, provided that the further restriction does not survive such
- relicensing or conveying.
- </p><p>
- If you add terms to a covered work in accord with this section, you must
- place, in the relevant source files, a statement of the additional terms
- that apply to those files, or a notice indicating where to find the
- applicable terms.
- </p><p>
- Additional terms, permissive or non-permissive, may be stated in the form
- of a separately written license, or stated as exceptions; the above
- requirements apply either way.
- </p><h2><a id="gpl-3-termination"></a>
- 8. Termination.
- </h2><p>
- You may not propagate or modify a covered work except as expressly provided
- under this License. Any attempt otherwise to propagate or modify it is
- void, and will automatically terminate your rights under this License
- (including any patent licenses granted under the third paragraph of section
- 11).
- </p><p>
- However, if you cease all violation of this License, then your license from
- a particular copyright holder is reinstated (a) provisionally, unless and
- until the copyright holder explicitly and finally terminates your license,
- and (b) permanently, if the copyright holder fails to notify you of the
- violation by some reasonable means prior to 60 days after the cessation.
- </p><p>
- Moreover, your license from a particular copyright holder is reinstated
- permanently if the copyright holder notifies you of the violation by some
- reasonable means, this is the first time you have received notice of
- violation of this License (for any work) from that copyright holder, and
- you cure the violation prior to 30 days after your receipt of the notice.
- </p><p>
- Termination of your rights under this section does not terminate the
- licenses of parties who have received copies or rights from you under this
- License. If your rights have been terminated and not permanently
- reinstated, you do not qualify to receive new licenses for the same
- material under section 10.
- </p><h2><a id="AcceptanceNotRequired"></a>
- 9. Acceptance Not Required for Having Copies.
- </h2><p>
- You are not required to accept this License in order to receive or run a
- copy of the Program. Ancillary propagation of a covered work occurring
- solely as a consequence of using peer-to-peer transmission to receive a
- copy likewise does not require acceptance. However, nothing other than
- this License grants you permission to propagate or modify any covered work.
- These actions infringe copyright if you do not accept this License.
- Therefore, by modifying or propagating a covered work, you indicate your
- acceptance of this License to do so.
- </p><h2><a id="AutomaticDownstream"></a>
- 10. Automatic Licensing of Downstream Recipients.
- </h2><p>
- Each time you convey a covered work, the recipient automatically receives a
- license from the original licensors, to run, modify and propagate that
- work, subject to this License. You are not responsible for enforcing
- compliance by third parties with this License.
- </p><p>
- An “entity transaction” is a transaction transferring control
- of an organization, or substantially all assets of one, or subdividing an
- organization, or merging organizations. If propagation of a covered work
- results from an entity transaction, each party to that transaction who
- receives a copy of the work also receives whatever licenses to the work the
- party’s predecessor in interest had or could give under the previous
- paragraph, plus a right to possession of the Corresponding Source of the
- work from the predecessor in interest, if the predecessor has it or can get
- it with reasonable efforts.
- </p><p>
- You may not impose any further restrictions on the exercise of the rights
- granted or affirmed under this License. For example, you may not impose a
- license fee, royalty, or other charge for exercise of rights granted under
- this License, and you may not initiate litigation (including a cross-claim
- or counterclaim in a lawsuit) alleging that any patent claim is infringed
- by making, using, selling, offering for sale, or importing the Program or
- any portion of it.
- </p><h2><a id="Patents"></a>
- 11. Patents.
- </h2><p>
- A “contributor” is a copyright holder who authorizes use under
- this License of the Program or a work on which the Program is based. The
- work thus licensed is called the contributor’s “contributor
- version”.
- </p><p>
- A contributor’s “essential patent claims” are all patent
- claims owned or controlled by the contributor, whether already acquired or
- hereafter acquired, that would be infringed by some manner, permitted by
- this License, of making, using, or selling its contributor version, but do
- not include claims that would be infringed only as a consequence of further
- modification of the contributor version. For purposes of this definition,
- “control” includes the right to grant patent sublicenses in a
- manner consistent with the requirements of this License.
- </p><p>
- Each contributor grants you a non-exclusive, worldwide, royalty-free patent
- license under the contributor’s essential patent claims, to make, use,
- sell, offer for sale, import and otherwise run, modify and propagate the
- contents of its contributor version.
- </p><p>
- In the following three paragraphs, a “patent license” is any
- express agreement or commitment, however denominated, not to enforce a
- patent (such as an express permission to practice a patent or covenant not
- to sue for patent infringement). To “grant” such a patent
- license to a party means to make such an agreement or commitment not to
- enforce a patent against the party.
- </p><p>
- If you convey a covered work, knowingly relying on a patent license, and the
- Corresponding Source of the work is not available for anyone to copy, free
- of charge and under the terms of this License, through a publicly available
- network server or other readily accessible means, then you must either (1)
- cause the Corresponding Source to be so available, or (2) arrange to deprive
- yourself of the benefit of the patent license for this particular work, or
- (3) arrange, in a manner consistent with the requirements of this License,
- to extend the patent license to downstream recipients. “Knowingly
- relying” means you have actual knowledge that, but for the patent
- license, your conveying the covered work in a country, or your
- recipient’s use of the covered work in a country, would infringe one
- or more identifiable patents in that country that you have reason to believe
- are valid.
- </p><p>
- If, pursuant to or in connection with a single transaction or arrangement,
- you convey, or propagate by procuring conveyance of, a covered work, and
- grant a patent license to some of the parties receiving the covered work
- authorizing them to use, propagate, modify or convey a specific copy of the
- covered work, then the patent license you grant is automatically extended to
- all recipients of the covered work and works based on it.
- </p><p>
- A patent license is “discriminatory” if it does not include
- within the scope of its coverage, prohibits the exercise of, or is
- conditioned on the non-exercise of one or more of the rights that are
- specifically granted under this License. You may not convey a covered work
- if you are a party to an arrangement with a third party that is in the
- business of distributing software, under which you make payment to the third
- party based on the extent of your activity of conveying the work, and under
- which the third party grants, to any of the parties who would receive the
- covered work from you, a discriminatory patent license (a) in connection
- with copies of the covered work conveyed by you (or copies made from those
- copies), or (b) primarily for and in connection with specific products or
- compilations that contain the covered work, unless you entered into that
- arrangement, or that patent license was granted, prior to 28 March 2007.
- </p><p>
- Nothing in this License shall be construed as excluding or limiting any
- implied license or other defenses to infringement that may otherwise be
- available to you under applicable patent law.
- </p><h2><a id="NoSurrender"></a>
- 12. No Surrender of Others’ Freedom.
- </h2><p>
- If conditions are imposed on you (whether by court order, agreement or
- otherwise) that contradict the conditions of this License, they do not
- excuse you from the conditions of this License. If you cannot convey a
- covered work so as to satisfy simultaneously your obligations under this
- License and any other pertinent obligations, then as a consequence you may
- not convey it at all. For example, if you agree to terms that obligate you
- to collect a royalty for further conveying from those to whom you convey the
- Program, the only way you could satisfy both those terms and this License
- would be to refrain entirely from conveying the Program.
- </p><h2><a id="UsedWithAGPL"></a>
- 13. Use with the <acronym class="acronym">GNU</acronym> Affero General Public License.
- </h2><p>
- Notwithstanding any other provision of this License, you have permission to
- link or combine any covered work with a work licensed under version 3 of the
- <acronym class="acronym">GNU</acronym> Affero General Public License into a single combined
- work, and to convey the resulting work. The terms of this License will
- continue to apply to the part which is the covered work, but the special
- requirements of the <acronym class="acronym">GNU</acronym> Affero General Public License,
- section 13, concerning interaction through a network will apply to the
- combination as such.
- </p><h2><a id="RevisedVersions"></a>
- 14. Revised Versions of this License.
- </h2><p>
- The Free Software Foundation may publish revised and/or new versions of the
- <acronym class="acronym">GNU</acronym> General Public License from time to time. Such new
- versions will be similar in spirit to the present version, but may differ in
- detail to address new problems or concerns.
- </p><p>
- Each version is given a distinguishing version number. If the Program
- specifies that a certain numbered version of the <acronym class="acronym">GNU</acronym>
- General Public License “or any later version” applies to it, you
- have the option of following the terms and conditions either of that
- numbered version or of any later version published by the Free Software
- Foundation. If the Program does not specify a version number of the
- <acronym class="acronym">GNU</acronym> General Public License, you may choose any version
- ever published by the Free Software Foundation.
- </p><p>
- If the Program specifies that a proxy can decide which future versions of
- the <acronym class="acronym">GNU</acronym> General Public License can be used, that
- proxy’s public statement of acceptance of a version permanently
- authorizes you to choose that version for the Program.
- </p><p>
- Later license versions may give you additional or different permissions.
- However, no additional obligations are imposed on any author or copyright
- holder as a result of your choosing to follow a later version.
- </p><h2><a id="WarrantyDisclaimer"></a>
- 15. Disclaimer of Warranty.
- </h2><p>
- THERE IS NO WARRANTY FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE
- LAW. EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR
- OTHER PARTIES PROVIDE THE PROGRAM “AS IS” WITHOUT WARRANTY OF
- ANY KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE
- IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE.
- THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH
- YOU. SHOULD THE PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL
- NECESSARY SERVICING, REPAIR OR CORRECTION.
- </p><h2><a id="LiabilityLimitation"></a>
- 16. Limitation of Liability.
- </h2><p>
- IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING WILL
- ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MODIFIES AND/OR CONVEYS THE
- PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, INCLUDING ANY
- GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING OUT OF THE USE
- OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED TO LOSS OF DATA
- OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD
- PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER PROGRAMS),
- EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF
- SUCH DAMAGES.
- </p><h2><a id="InterpretationSecs1516"></a>
- 17. Interpretation of Sections 15 and 16.
- </h2><p>
- If the disclaimer of warranty and limitation of liability provided above
- cannot be given local legal effect according to their terms, reviewing
- courts shall apply local law that most closely approximates an absolute
- waiver of all civil liability in connection with the Program, unless a
- warranty or assumption of liability accompanies a copy of the Program in
- return for a fee.

- END OF TERMS AND CONDITIONS
- </h2><h2><a id="HowToApply"></a>
- How to Apply These Terms to Your New Programs
- </h2><p>
- If you develop a new program, and you want it to be of the greatest possible
- use to the public, the best way to achieve this is to make it free software
- which everyone can redistribute and change under these terms.
- </p><p>
- To do so, attach the following notices to the program. It is safest to
- attach them to the start of each source file to most effectively state the
- exclusion of warranty; and each file should have at least the
- “copyright” line and a pointer to where the full notice is
- found.
- </p><pre class="screen">
-<em class="replaceable"><code>one line to give the program’s name and a brief idea of what it does.</code></em>
-Copyright (C) <em class="replaceable"><code>year</code></em> <em class="replaceable"><code>name of author</code></em>
-
-This program is free software: you can redistribute it and/or modify
-it under the terms of the <acronym class="acronym">GNU</acronym> General Public License as published by
-the Free Software Foundation, either version 3 of the License, or
-(at your option) any later version.
-
-This program is distributed in the hope that it will be useful,
-but WITHOUT ANY WARRANTY; without even the implied warranty of
-MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the
-<acronym class="acronym">GNU</acronym> General Public License for more details.
-
-You should have received a copy of the <acronym class="acronym">GNU</acronym> General Public License
-along with this program. If not, see <a class="ulink" href="http://www.gnu.org/licenses/" target="_top">http://www.gnu.org/licenses/</a>.
- </pre><p>
- Also add information on how to contact you by electronic and paper mail.
- </p><p>
- If the program does terminal interaction, make it output a short notice like
- this when it starts in an interactive mode:
- </p><pre class="screen">
-<em class="replaceable"><code>program</code></em> Copyright (C) <em class="replaceable"><code>year</code></em> <em class="replaceable"><code>name of author</code></em>
-This program comes with ABSOLUTELY NO WARRANTY; for details type ‘<code class="literal">show w</code>’.
-This is free software, and you are welcome to redistribute it
-under certain conditions; type ‘<code class="literal">show c</code>’ for details.
- </pre><p>
- The hypothetical commands ‘<code class="literal">show w</code>’ and
- ‘<code class="literal">show c</code>’ should show the appropriate parts of
- the General Public License. Of course, your program’s commands might be
- different; for a GUI interface, you would use an “about box”.
- </p><p>
- You should also get your employer (if you work as a programmer) or school,
- if any, to sign a “copyright disclaimer” for the program, if
- necessary. For more information on this, and how to apply and follow the
- <acronym class="acronym">GNU</acronym> <acronym class="acronym">GPL</acronym>, see
- <a class="ulink" href="http://www.gnu.org/licenses/" target="_top">http://www.gnu.org/licenses/</a>.
- </p><p>
- The <acronym class="acronym">GNU</acronym> General Public License does not permit
- incorporating your program into proprietary programs. If your program is a
- subroutine library, you may consider it more useful to permit linking
- proprietary applications with the library. If this is what you want to do,
- use the <acronym class="acronym">GNU</acronym> Lesser General Public License instead of this
- License. But first, please read <a class="ulink" href="http://www.gnu.org/philosophy/why-not-lgpl.html" target="_top">http://www.gnu.org/philosophy/why-not-lgpl.html</a>.
