| Everyone is permitted to copy and distribute verbatim copies of this license |
| document, but changing it is not allowed. |
| </para> |
| <bridgehead xml:id="gpl-3-preamble" renderas="sect1"> |
| Preamble |
| </bridgehead> |
| <para> |
| The <acronym>GNU</acronym> General Public License is a free, copyleft |
| license for software and other kinds of works. |
| </para> |
| <para> |
| The licenses for most software and other practical works are designed to |
| take away your freedom to share and change the works. By contrast, the |
| <acronym>GNU</acronym> General Public License is intended to guarantee your |
| freedom to share and change all versions of a program—to make sure it |
| remains free software for all its users. We, the Free Software Foundation, |
| use the <acronym>GNU</acronym> General Public License for most of our |
| software; it applies also to any other work released this way by its |
| authors. You can apply it to your programs, too. |
| </para> |
| <para> |
| 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. |
| </para> |
| <para> |
| 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. |
| </para> |
| <para> |
| 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. |
| </para> |
| <para> |
| Developers that use the <acronym>GNU</acronym> <acronym>GPL</acronym> |
| protect your rights with two steps: (1) assert copyright on the software, |
| and (2) offer you this License giving you legal permission to copy, |
| distribute and/or modify it. |
| </para> |
| <para> |
| For the developers’ and authors’ protection, the |
| <acronym>GPL</acronym> clearly explains that there is no warranty for this |
| free software. For both users’ and authors’ sake, the |
| <acronym>GPL</acronym> requires that modified versions be marked as changed, |
| so that their problems will not be attributed erroneously to authors of |
| previous versions. |
| </para> |
| <para> |
| Some devices are designed to deny users access to install or run modified |
| versions of the software inside them, although the manufacturer can do so. |
| This is fundamentally incompatible with the aim of protecting users’ |
| freedom to change the software. The systematic pattern of such abuse occurs |
| in the area of products for individuals to use, which is precisely where it |
| is most unacceptable. Therefore, we have designed this version of the |
| <acronym>GPL</acronym> to prohibit the practice for those products. If such |
| problems arise substantially in other domains, we stand ready to extend this |
| provision to those domains in future versions of the <acronym>GPL</acronym>, |
| as needed to protect the freedom of users. |
| </para> |
| <para> |
| Finally, every program is threatened constantly by software patents. States |
| should not allow patents to restrict development and use of software on |
| general-purpose computers, but in those that do, we wish to avoid the |
| special danger that patents applied to a free program could make it |
| effectively proprietary. To prevent this, the <acronym>GPL</acronym> |
| assures that patents cannot be used to render the program non-free. |
| </para> |
| <para> |
| The precise terms and conditions for copying, distribution and modification |
| follow. |

| TERMS AND CONDITIONS |
| </bridgehead> |
| <bridgehead xml:id="gpl-3-definitions" renderas="sect1"> |
| 0. Definitions. |
| </bridgehead> |
| <para> |
| “This License” refers to version 3 of the <acronym>GNU</acronym> |
| General Public License. |
| </para> |
| <para> |
| “Copyright” also means copyright-like laws that apply to other |
| kinds of works, such as semiconductor masks. |
| </para> |
| <para> |
| “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. |
| </para> |
| <para> |
| 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. |
| </para> |
| <para> |
| A “covered work” means either the unmodified Program or a work |
| based on the Program. |
| </para> |
| <para> |
| 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. |
| </para> |
| <para> |
| 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. |
| </para> |
| <para> |
| 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. |
| </para> |
| <bridgehead xml:id="SourceCode" renderas="sect1"> |
| 1. Source Code. |
| </bridgehead> |
| <para> |
| 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. |
| </para> |
| <para> |
| 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. |
| </para> |
| <para> |
| 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. |
| </para> |
| <para> |
| 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. |
| </para> |
| <para> |
| The Corresponding Source need not include anything that users can regenerate |
| automatically from other parts of the Corresponding Source. |
| </para> |
| <para> |
| The Corresponding Source for a work in source code form is that same work. |
| </para> |
| <bridgehead xml:id="BasicPermissions" renderas="sect1"> |
| 2. Basic Permissions. |
| </bridgehead> |
| <para> |
| 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. |
| </para> |
| <para> |
| 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. |
| </para> |
| <para> |
| Conveying under any other circumstances is permitted solely under the |
| conditions stated below. Sublicensing is not allowed; section 10 makes it |
| unnecessary. |
| </para> |
| <bridgehead xml:id="Protecting" renderas="sect1"> |
| 3. Protecting Users’ Legal Rights From Anti-Circumvention Law. |
| </bridgehead> |
| <para> |
| 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. |
| </para> |
| <para> |
| 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. |
| </para> |
| <bridgehead xml:id="ConveyingVerbatim" renderas="sect1"> |
| 4. Conveying Verbatim Copies. |
| </bridgehead> |
| <para> |
| 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. |
| </para> |
| <para> |
| 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. |

| 5. Conveying Modified Source Versions. |
| </bridgehead> |
| <para> |
| 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: |

| <listitem> |
| <para> |
| 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”. |
| </para> |
| </listitem> |
| <listitem> |
| <para> |
| 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. |
| </para> |
| </listitem> |
| <listitem> |
| <para> |
| 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. |
| </para> |
| </listitem> |
| </orderedlist> |
| <para> |
| 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. |

| </bridgehead> |
| <para> |
| You may convey a covered work in object code form under the terms of |

| 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. |
| </para> |
| </listitem> |
| <listitem> |
| <para> |

| <para> |
| Convey the object code by offering access from a designated place |
| (gratis or for a charge), and offer equivalent access to 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. |
| </para> |
| </listitem> |
| <listitem> |
| <para> |
| Convey the object code using peer-to-peer transmission, provided you |

| subsection 6d. |
| </para> |
| </listitem> |
| </orderedlist> |
| <para> |
| 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. |
| </para> |
| <para> |
| 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. |
| </para> |
| <para> |
| “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. |
| </para> |
| <para> |
| If you convey an object code work under this section in, or with, or |
| specifically for use in, a User Product, and the conveying occurs as part of |
| a transaction in which the right of possession and use of the User Product |
| is transferred to the recipient in perpetuity or for a fixed term |
| (regardless of how the transaction is characterized), the Corresponding |
| Source conveyed under this section must be accompanied by the Installation |
| Information. But this requirement does not apply if neither you nor any |
| third party retains the ability to install modified object code on the User |
| Product (for example, the work has been installed in |
| <acronym>ROM</acronym>). |
| </para> |
| <para> |
| 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. |
| </para> |
| <para> |
| 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. |

| <bridgehead xml:id="AdditionalTerms" renderas="sect1"> |
| 7. Additional Terms. |
| </bridgehead> |
| <para> |
| “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. |

| 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 |

| <para> |
| You may not propagate or modify a covered work except as expressly provided |

| Moreover, your license from a particular copyright holder is reinstated |
| permanently if the copyright holder notifies you of the violation by some |

| 9. Acceptance Not Required for Having Copies. |
| </bridgehead> |
| <para> |
| 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. |

| <para> |
| An “entity transaction” is a transaction transferring control |

| 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 |

| 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 |

| 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. |

| 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. |

| 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. |

| 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. |
| </para> |
| <para> |
| 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 |
