- <h3 style="text-align: center;">GNU GENERAL PUBLIC LICENSE</h3>
- <p style="text-align: center;">Version 3, 29 June 2007</p>
- <p>Copyright © 2007 Free Software Foundation, Inc.
- <<a href="http://fsf.org/">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>
- <h3><a name="preamble"></a>Preamble</h3>
- <p>The GNU 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 GNU 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
- GNU 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 GNU GPL 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 GPL clearly explains
- that there is no warranty for this free software. For both users' and
- authors' sake, the GPL 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 GPL 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 GPL, 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 GPL 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>
- <h3><a name="terms"></a>TERMS AND CONDITIONS</h3>
- <h4><a name="section0"></a>0. Definitions.</h4>
- <p>“This License” refers to version 3 of the GNU 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>
- <h4><a name="section1"></a>1. Source Code.</h4>
- <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>
- <h4><a name="section2"></a>2. Basic Permissions.</h4>
- <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>
- <h4><a name="section3"></a>3. Protecting Users' Legal Rights From Anti-Circumvention Law.</h4>
- <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>
- <h4><a name="section4"></a>4. Conveying Verbatim Copies.</h4>
- <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>
- <h4><a name="section5"></a>5. Conveying Modified Source Versions.</h4>
- <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>
- <ul>
- <li>a) The work must carry prominent notices stating that you modified
- it, and giving a relevant date.</li>
- <li>b) 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”.</li>
- <li>c) 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.</li>
- <li>d) 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.</li>
- </ul>
- <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>
- <h4><a name="section6"></a>6. Conveying Non-Source Forms.</h4>
- <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>
- <ul>
- <li>a) 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.</li>
- <li>b) 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.</li>
- <li>c) 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.</li>
- <li>d) 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.</li>
- <li>e) 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.</li>
- </ul>
- <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 ROM).</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>
- <h4><a name="section7"></a>7. Additional Terms.</h4>
- <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>
- <ul>
- <li>a) Disclaiming warranty or limiting liability differently from the
- terms of sections 15 and 16 of this License; or</li>
- <li>b) 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</li>
- <li>c) 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</li>
- <li>d) Limiting the use for publicity purposes of names of licensors or
- authors of the material; or</li>
- <li>e) Declining to grant rights under trademark law for use of some
- trade names, trademarks, or service marks; or</li>
- <li>f) 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.</li>
- </ul>
- <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>
- <h4><a name="section8"></a>8. Termination.</h4>
- <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>
- <h4><a name="section9"></a>9. Acceptance Not Required for Having Copies.</h4>
- <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>
- <h4><a name="section10"></a>10. Automatic Licensing of Downstream Recipients.</h4>
- <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>
- <h4><a name="section11"></a>11. Patents.</h4>
- <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>
- <h4><a name="section12"></a>12. No Surrender of Others' Freedom.</h4>
- <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>
- <h4><a name="section13"></a>13. Use with the GNU Affero General Public License.</h4>
- <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 GNU 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 GNU Affero General Public License,
- section 13, concerning interaction through a network will apply to the
- combination as such.</p>
- <h4><a name="section14"></a>14. Revised Versions of this License.</h4>
- <p>The Free Software Foundation may publish revised and/or new versions of
- the GNU 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 GNU 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
- GNU 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 GNU 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>
- <h4><a name="section15"></a>15. Disclaimer of Warranty.</h4>
- <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>
- <h4><a name="section16"></a>16. Limitation of Liability.</h4>
- <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>
- <h4><a name="section17"></a>17. Interpretation of Sections 15 and 16.</h4>
- <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.</p>
- <p>END OF TERMS AND CONDITIONS</p>
- <h3><a name="howto"></a>How to Apply These Terms to Your New Programs</h3>
- <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> <one line to give the program's name and a brief idea of what it does.>
- Copyright (C) <year> <name of author>
- This program is free software: you can redistribute it and/or modify
- it under the terms of the GNU 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
- GNU General Public License for more details.
- You should have received a copy of the GNU General Public License
- along with this program. If not, see <http://www.gnu.org/licenses/>.
- </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> <program> Copyright (C) <year> <name of author>
- This program comes with ABSOLUTELY NO WARRANTY; for details type `show w'.
- This is free software, and you are welcome to redistribute it
- under certain conditions; type `show c' for details.
- </pre>
- <p>The hypothetical commands `show w' and `show c' 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 GNU GPL, see
- <<a href="http://www.gnu.org/licenses/">http://www.gnu.org/licenses/</a>>.</p>
- <p>The GNU 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 GNU Lesser General
- Public License instead of this License. But first, please read
