| .SS "Preamble" |
| .IX Subsection "Preamble" |
| The \s-1GNU\s0 General Public License is a free, copyleft license for |
| software and other kinds of works. |
| .PP |
| 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 \s-1GNU\s0 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 \s-1GNU\s0 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. |
| .PP |
| 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. |
| .PP |
| 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. |
| .PP |
| 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. |
| .PP |
| Developers that use the \s-1GNU GPL\s0 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. |
| .PP |
| For the developers' and authors' protection, the \s-1GPL\s0 clearly explains |
| that there is no warranty for this free software. For both users' and |
| authors' sake, the \s-1GPL\s0 requires that modified versions be marked as |
| changed, so that their problems will not be attributed erroneously to |
| authors of previous versions. |
| .PP |
| 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 \s-1GPL\s0 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 \s-1GPL,\s0 as needed to protect the |
| freedom of users. |
| .PP |
| 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 \s-1GPL\s0 |
| assures that patents cannot be used to render the program non-free. |
| .PP |
| The precise terms and conditions for copying, distribution and |
| modification follow. |
| .SS "\s-1TERMS AND CONDITIONS\s0" |
| .IX Subsection "TERMS AND CONDITIONS" |
| .IP "0. Definitions." 4 |
| .IX Item "0. Definitions." |
| \&\*(L"This License\*(R" refers to version 3 of the \s-1GNU\s0 General Public License. |
| .Sp |
| \&\*(L"Copyright\*(R" also means copyright-like laws that apply to other kinds |
| of works, such as semiconductor masks. |
| .Sp |
| \&\*(L"The Program\*(R" refers to any copyrightable work licensed under this |
| License. Each licensee is addressed as \*(L"you\*(R". \*(L"Licensees\*(R" and |
| \&\*(L"recipients\*(R" may be individuals or organizations. |
| .Sp |
| To \*(L"modify\*(R" 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 \*(L"modified version\*(R" of |
| the earlier work or a work \*(L"based on\*(R" the earlier work. |
| .Sp |
| A \*(L"covered work\*(R" means either the unmodified Program or a work based |
| on the Program. |
| .Sp |
| To \*(L"propagate\*(R" 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. |
| .Sp |
| To \*(L"convey\*(R" 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. |
| .Sp |
| An interactive user interface displays \*(L"Appropriate Legal Notices\*(R" 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. |
| .IP "1. Source Code." 4 |
| .IX Item "1. Source Code." |
| The \*(L"source code\*(R" for a work means the preferred form of the work for |
| making modifications to it. \*(L"Object code\*(R" means any non-source form |
| of a work. |
| .Sp |
| A \*(L"Standard Interface\*(R" 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. |
| .Sp |
| The \*(L"System Libraries\*(R" 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 |
| \&\*(L"Major Component\*(R", 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. |
| .Sp |
| The \*(L"Corresponding Source\*(R" 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. |
| .Sp |
| The Corresponding Source need not include anything that users can |
| regenerate automatically from other parts of the Corresponding Source. |
| .Sp |
| The Corresponding Source for a work in source code form is that same |
| work. |
| .IP "2. Basic Permissions." 4 |
| .IX Item "2. 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. |
| .Sp |
| 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. |
| .Sp |
| Conveying under any other circumstances is permitted solely under the |
| conditions stated below. Sublicensing is not allowed; section 10 |
| makes it unnecessary. |
| .IP "3. Protecting Users' Legal Rights From Anti-Circumvention Law." 4 |
| .IX Item "3. 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 \s-1WIPO\s0 copyright treaty adopted on 20 December 1996, or |
| similar laws prohibiting or restricting circumvention of such |
| measures. |
| .Sp |
| 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. |
| .IP "4. Conveying Verbatim Copies." 4 |
| .IX Item "4. 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. |
| .Sp |
| 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. |
| .IP "5. Conveying Modified Source Versions." 4 |
| .IX Item "5. 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: |
| .RS 4 |
| .IP "a." 4 |
| .IX Item "a." |
| The work must carry prominent notices stating that you modified it, |
| and giving a relevant date. |
| .IP "b." 4 |
| .IX Item "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 \*(L"keep intact all |
| notices\*(R". |
| .IP "c." 4 |
| .IX Item "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. |
| .IP "d." 4 |
| .IX Item "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. |
| .RE |
| .RS 4 |
| .Sp |
| 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 |
| \&\*(L"aggregate\*(R" 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. |
| .RE |
| .IP "6. Conveying Non-Source Forms." 4 |
| .IX Item "6. 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: |
| .RS 4 |
| .IP "a." 4 |
| .IX Item "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. |
| .IP "b." 4 |
| .IX Item "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. |
| .IP "c." 4 |
| .IX Item "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. |
| .IP "d." 4 |
| .IX Item "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. |
| .IP "e." 4 |
| .IX Item "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. |
| .RE |

| A \*(L"User Product\*(R" is either (1) a \*(L"consumer product\*(R", 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, |
| \&\*(L"normally used\*(R" 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. |
| .Sp |
| \&\*(L"Installation Information\*(R" 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. |
| .Sp |
| 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 \s-1ROM\s0). |
| .Sp |
| 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. |
| .Sp |
| 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. |

| All other non-permissive additional terms are considered \*(L"further |
| restrictions\*(R" 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. |
| .Sp |
| 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. |
| .Sp |
| 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. |

| .IP "8. Termination." 4 |
| .IX Item "8. 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). |
| .Sp |
| 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. |
| .Sp |
| 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. |
| .Sp |
| 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. |
| .IP "9. Acceptance Not Required for Having Copies." 4 |
| .IX Item "9. 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. |
| .IP "10. Automatic Licensing of Downstream Recipients." 4 |
| .IX Item "10. 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. |
| .Sp |
| An \*(L"entity transaction\*(R" 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. |
| .Sp |
| 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. |
| .IP "11. Patents." 4 |
| .IX Item "11. Patents." |
| A \*(L"contributor\*(R" 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 \*(L"contributor version\*(R". |
| .Sp |
| A contributor's \*(L"essential patent claims\*(R" 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, \*(L"control\*(R" includes the right to grant |
| patent sublicenses in a manner consistent with the requirements of |
| this License. |
| .Sp |
| 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. |
| .Sp |
| In the following three paragraphs, a \*(L"patent license\*(R" 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 \*(L"grant\*(R" such a patent license to a |
| party means to make such an agreement or commitment not to enforce a |
| patent against the party. |
| .Sp |
| 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. \*(L"Knowingly relying\*(R" 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. |
| .Sp |
| 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. |
| .Sp |
| A patent license is \*(L"discriminatory\*(R" 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. |
| .Sp |
| 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. |
| .IP "12. No Surrender of Others' Freedom." 4 |
| .IX Item "12. 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. |
| .IP "13. Use with the \s-1GNU\s0 Affero General Public License." 4 |
| .IX Item "13. 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 \s-1GNU\s0 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 \s-1GNU\s0 Affero General Public License, |
| section 13, concerning interaction through a network will apply to the |
| combination as such. |
| .IP "14. Revised Versions of this License." 4 |
| .IX Item "14. Revised Versions of this License." |
| The Free Software Foundation may publish revised and/or new versions |
| of the \s-1GNU\s0 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. |
| .Sp |
| Each version is given a distinguishing version number. If the Program |
| specifies that a certain numbered version of the \s-1GNU\s0 General Public |
| License \*(L"or any later version\*(R" 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 \s-1GNU\s0 General |
| Public License, you may choose any version ever published by the Free |
| Software Foundation. |
| .Sp |
| If the Program specifies that a proxy can decide which future versions |
| of the \s-1GNU\s0 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. |
| .Sp |
| 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. |

| To do so, attach the following notices to the program. It is safest |
