+ |
+@heading Preamble |
+ |
+The GNU General Public License is a free, copyleft license for |
+software and other kinds of works. |
+ |
+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. |
+ |
+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. |
+ |
+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. |
+ |
+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. |
+ |
+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. |
+ |
+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. |
+ |
+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. |
+ |
+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. |
+ |
+The precise terms and conditions for copying, distribution and |
+modification follow. |
+ |
+@heading TERMS AND CONDITIONS |
+ |
+@enumerate 0 |
+@item Definitions. |
+ |
+``This License'' refers to version 3 of the GNU General Public License. |
+ |
+``Copyright'' also means copyright-like laws that apply to other kinds |
+of works, such as semiconductor masks. |
+ |
+``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. |
+ |
+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. |
+ |
+A ``covered work'' means either the unmodified Program or a work based |
+on the Program. |
+ |
+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. |
+ |
+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. |
+ |
+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. |
+ |
+@item Source Code. |
+ |
+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. |
+ |
+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. |
+ |
+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. |
+ |
+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. |
+ |
+The Corresponding Source need not include anything that users can |
+regenerate automatically from other parts of the Corresponding Source. |
+ |
+The Corresponding Source for a work in source code form is that same |
+work. |
+ |
+@item Basic Permissions. |
+ |
+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. |
+ |
+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. |
+ |
+Conveying under any other circumstances is permitted solely under the |
+conditions stated below. Sublicensing is not allowed; section 10 |
+makes it unnecessary. |
+ |
+@item Protecting Users' Legal Rights From Anti-Circumvention Law. |
+ |
+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. |
+ |
+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. |
+ |
+@item Conveying Verbatim Copies. |
+ |
+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. |
+ |
+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. |
+ |
+@item Conveying Modified Source Versions. |
+ |
+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: |
+ |
+@enumerate a |
+@item |
+The work must carry prominent notices stating that you modified it, |
+and giving a relevant date. |
+ |
+@item |
+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''. |
+ |
+@item |
+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. |
+ |
+@item |
+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. |
+@end enumerate |
+ |
+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. |
+ |
+@item Conveying Non-Source Forms. |
+ |
+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: |
+ |
+@enumerate a |
+@item |
+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. |
+ |
+@item |
+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. |
+ |
+@item |
+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. |
+ |
+@item |
+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. |
+ |
+@item |
+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. |
+ |
+@end enumerate |
+ |
+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. |
+ |
+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. |
+ |
+``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. |
+ |
+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). |
+ |
+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. |
+ |
+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. |
+ |
+@item Additional Terms. |
+ |
+``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. |
+ |
+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. |
+ |
+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: |
+ |
+@enumerate a |
+@item |
+Disclaiming warranty or limiting liability differently from the terms |
+of sections 15 and 16 of this License; or |
+ |
+@item |
+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 |
+ |
+@item |
+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 |
+ |
+@item |
+Limiting the use for publicity purposes of names of licensors or |
+authors of the material; or |
+ |
+@item |
+Declining to grant rights under trademark law for use of some trade |
+names, trademarks, or service marks; or |
+ |
+@item |
+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. |
+@end enumerate |
+ |
+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. |
+ |
+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. |
+ |
+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. |
+ |
+@item Termination. |
+ |
+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). |
+ |
+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. |
+ |
+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. |
+ |
+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. |
+ |
+@item Acceptance Not Required for Having Copies. |
+ |
+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. |
+ |
+@item Automatic Licensing of Downstream Recipients. |
+ |
+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. |
+ |
+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. |
+ |
+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. |
+ |
+@item Patents. |
+ |
+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''. |
+ |
+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. |
+ |
+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. |
+ |
+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. |
+ |
+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. |
+ |
+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. |
+ |
+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. |
+ |
+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. |
+ |
+@item No Surrender of Others' Freedom. |
+ |
+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. |
+ |
+@item Use with the GNU Affero General Public License. |
+ |
+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. |
+ |
+@item Revised Versions of this License. |
+ |
+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. |
+ |
+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. |
+ |
+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. |
+ |
+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. |
+ |
+@item Disclaimer of Warranty. |
+ |
+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. |
+ |
+@item Limitation of Liability. |
+ |
+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. |
+ |
+@item Interpretation of Sections 15 and 16. |
+ |
+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. |

+@heading How to Apply These Terms to Your New Programs |
+ |
+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. |
+ |
+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. |
+ |
+@smallexample |
+@var{one line to give the program's name and a brief idea of what it does.} |
+Copyright (C) @var{year} @var{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 @url{http://www.gnu.org/licenses/}. |
+@end smallexample |
+ |
+Also add information on how to contact you by electronic and paper mail. |
+ |
+If the program does terminal interaction, make it output a short |
+notice like this when it starts in an interactive mode: |
+ |
+@smallexample |
+@var{program} Copyright (C) @var{year} @var{name of author} |
+This program comes with ABSOLUTELY NO WARRANTY; for details type @samp{show w}. |
+This is free software, and you are welcome to redistribute it |
+under certain conditions; type @samp{show c} for details. |
+@end smallexample |
+ |
+The hypothetical commands @samp{show w} and @samp{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''. |
+ |
+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 |
+@url{http://www.gnu.org/licenses/}. |
+ |
+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 @url{http://www.gnu.org/philosophy/why-not-lgpl.html}. |
