| | 17 | document, but changing it is not allowed. |

| | 20 | Preamble |
| | 21 | </bridgehead> |
| | 22 | <para> |
| | 23 | The <acronym>GNU</acronym> General Public License is a free, copyleft |
| | 24 | license for software and other kinds of works. |
| | 25 | </para> |
| | 26 | <para> |
| | 27 | The licenses for most software and other practical works are designed to |
| | 28 | take away your freedom to share and change the works. By contrast, the |
| | 29 | <acronym>GNU</acronym> General Public License is intended to guarantee your |
| | 30 | freedom to share and change all versions of a program—to make sure it |
| | 31 | remains free software for all its users. We, the Free Software Foundation, |
| | 32 | use the <acronym>GNU</acronym> General Public License for most of our |
| | 33 | software; it applies also to any other work released this way by its |
| | 34 | authors. You can apply it to your programs, too. |
| | 35 | </para> |
| | 36 | <para> |
| | 37 | When we speak of free software, we are referring to freedom, not price. Our |
| | 38 | General Public Licenses are designed to make sure that you have the freedom |
| | 39 | to distribute copies of free software (and charge for them if you wish), |
| | 40 | that you receive source code or can get it if you want it, that you can |
| | 41 | change the software or use pieces of it in new free programs, and that you |
| | 42 | know you can do these things. |
| | 43 | </para> |
| | 44 | <para> |
| | 45 | To protect your rights, we need to prevent others from denying you these |
| | 46 | rights or asking you to surrender the rights. Therefore, you have certain |
| | 47 | responsibilities if you distribute copies of the software, or if you modify |
| | 48 | it: responsibilities to respect the freedom of others. |
| | 49 | </para> |
| | 50 | <para> |
| | 51 | For example, if you distribute copies of such a program, whether gratis or |
| | 52 | for a fee, you must pass on to the recipients the same freedoms that you |
| | 53 | received. You must make sure that they, too, receive or can get the source |
| | 54 | code. And you must show them these terms so they know their rights. |
| | 55 | </para> |
| | 56 | <para> |
| | 57 | Developers that use the <acronym>GNU</acronym> <acronym>GPL</acronym> |
| | 58 | protect your rights with two steps: (1) assert copyright on the software, |
| | 59 | and (2) offer you this License giving you legal permission to copy, |
| | 60 | distribute and/or modify it. |
| | 61 | </para> |
| | 62 | <para> |
| | 63 | For the developers’ and authors’ protection, the |
| | 64 | <acronym>GPL</acronym> clearly explains that there is no warranty for this |
| | 65 | free software. For both users’ and authors’ sake, the |
| | 66 | <acronym>GPL</acronym> requires that modified versions be marked as changed, |
| | 67 | so that their problems will not be attributed erroneously to authors of |
| | 68 | previous versions. |
| | 69 | </para> |
| | 70 | <para> |
| | 71 | Some devices are designed to deny users access to install or run modified |
| | 72 | versions of the software inside them, although the manufacturer can do so. |
| | 73 | This is fundamentally incompatible with the aim of protecting users’ |
| | 74 | freedom to change the software. The systematic pattern of such abuse occurs |
| | 75 | in the area of products for individuals to use, which is precisely where it |
| | 76 | is most unacceptable. Therefore, we have designed this version of the |
| | 77 | <acronym>GPL</acronym> to prohibit the practice for those products. If such |
| | 78 | problems arise substantially in other domains, we stand ready to extend this |
| | 79 | provision to those domains in future versions of the <acronym>GPL</acronym>, |
| | 80 | as needed to protect the freedom of users. |
| | 81 | </para> |
| | 82 | <para> |
| | 83 | Finally, every program is threatened constantly by software patents. States |
| | 84 | should not allow patents to restrict development and use of software on |
| | 85 | general-purpose computers, but in those that do, we wish to avoid the |
| | 86 | special danger that patents applied to a free program could make it |
| | 87 | effectively proprietary. To prevent this, the <acronym>GPL</acronym> |
| | 88 | assures that patents cannot be used to render the program non-free. |

| | 92 | follow. |

| | 100 | <para> |
| | 101 | “This License” refers to version 3 of the <acronym>GNU</acronym> |
| | 102 | General Public License. |
| | 103 | </para> |
| | 104 | <para> |
| | 105 | “Copyright” also means copyright-like laws that apply to other |
| | 106 | kinds of works, such as semiconductor masks. |
| | 107 | </para> |
| | 108 | <para> |
| | 109 | “The Program” refers to any copyrightable work licensed under |
| | 110 | this License. Each licensee is addressed as “you”. |
| | 111 | “Licensees” and “recipients” may be individuals or |
| | 112 | organizations. |
| | 113 | </para> |
| | 114 | <para> |
| | 115 | To “modify” a work means to copy from or adapt all or part of |
| | 116 | the work in a fashion requiring copyright permission, other than the making |
| | 117 | of an exact copy. The resulting work is called a “modified |
| | 118 | version” of the earlier work or a work “based on” the |
| | 119 | earlier work. |
| | 120 | </para> |
| | 121 | <para> |
| | 122 | A “covered work” means either the unmodified Program or a work |
| | 123 | based on the Program. |
| | 124 | </para> |
| | 125 | <para> |
| | 126 | To “propagate” a work means to do anything with it that, without |
| | 127 | permission, would make you directly or secondarily liable for infringement |
| | 128 | under applicable copyright law, except executing it on a computer or |
| | 129 | modifying a private copy. Propagation includes copying, distribution (with |
| | 130 | or without modification), making available to the public, and in some |
| | 131 | countries other activities as well. |
| | 132 | </para> |
| | 133 | <para> |
| | 134 | To “convey” a work means any kind of propagation that enables |
| | 135 | other parties to make or receive copies. Mere interaction with a user |
| | 136 | through a computer network, with no transfer of a copy, is not conveying. |
| | 137 | </para> |
| | 138 | <para> |
| | 139 | An interactive user interface displays “Appropriate Legal |
| | 140 | Notices” to the extent that it includes a convenient and prominently |
| | 141 | visible feature that (1) displays an appropriate copyright notice, and (2) |
| | 142 | tells the user that there is no warranty for the work (except to the extent |
| | 143 | that warranties are provided), that licensees may convey the work under this |
| | 144 | License, and how to view a copy of this License. If the interface presents |
| | 145 | a list of user commands or options, such as a menu, a prominent item in the |
| | 146 | list meets this criterion. |
| | 147 | </para> |
| | 148 | <bridgehead id="SourceCode" renderas="sect1"> |
| | 149 | 1. Source Code. |
| | 150 | </bridgehead> |
| | 151 | <para> |
| | 152 | The “source code” for a work means the preferred form of the |
| | 153 | work for making modifications to it. “Object code” means any |
| | 154 | non-source form of a work. |
| | 155 | </para> |
| | 156 | <para> |
| | 157 | A “Standard Interface” means an interface that either is an |
| | 158 | official standard defined by a recognized standards body, or, in the case of |
| | 159 | interfaces specified for a particular programming language, one that is |
| | 160 | widely used among developers working in that language. |
| | 161 | </para> |
| | 162 | <para> |
| | 163 | The “System Libraries” of an executable work include anything, |
| | 164 | other than the work as a whole, that (a) is included in the normal form of |
| | 165 | packaging a Major Component, but which is not part of that Major Component, |
| | 166 | and (b) serves only to enable use of the work with that Major Component, or |
| | 167 | to implement a Standard Interface for which an implementation is available |
| | 168 | to the public in source code form. A “Major Component”, in this |
| | 169 | context, means a major essential component (kernel, window system, and so |
| | 170 | on) of the specific operating system (if any) on which the executable work |
| | 171 | runs, or a compiler used to produce the work, or an object code interpreter |
| | 172 | used to run it. |
| | 173 | </para> |
| | 174 | <para> |
| | 175 | The “Corresponding Source” for a work in object code form means |
| | 176 | all the source code needed to generate, install, and (for an executable |
| | 177 | work) run the object code and to modify the work, including scripts to |
| | 178 | control those activities. However, it does not include the work’s |
| | 179 | System Libraries, or general-purpose tools or generally available free |
| | 180 | programs which are used unmodified in performing those activities but which |
| | 181 | are not part of the work. For example, Corresponding Source includes |
| | 182 | interface definition files associated with source files for the work, and |
| | 183 | the source code for shared libraries and dynamically linked subprograms that |
| | 184 | the work is specifically designed to require, such as by intimate data |
| | 185 | communication or control flow between those subprograms and other parts of |
| | 186 | the work. |
| | 187 | </para> |
| | 188 | <para> |
| | 189 | The Corresponding Source need not include anything that users can regenerate |
| | 190 | automatically from other parts of the Corresponding Source. |
| | 191 | </para> |
| | 192 | <para> |
| | 193 | The Corresponding Source for a work in source code form is that same work. |

| | 199 | All rights granted under this License are granted for the term of copyright |
| | 200 | on the Program, and are irrevocable provided the stated conditions are met. |
| | 201 | This License explicitly affirms your unlimited permission to run the |
| | 202 | unmodified Program. The output from running a covered work is covered by |
| | 203 | this License only if the output, given its content, constitutes a covered |
| | 204 | work. This License acknowledges your rights of fair use or other |
| | 205 | equivalent, as provided by copyright law. |

| | 207 | <para> |
| | 208 | You may make, run and propagate covered works that you do not convey, |
| | 209 | without conditions so long as your license otherwise remains in force. You |
| | 210 | may convey covered works to others for the sole purpose of having them make |
| | 211 | modifications exclusively for you, or provide you with facilities for |
| | 212 | running those works, provided that you comply with the terms of this License |
| | 213 | in conveying all material for which you do not control copyright. Those |
| | 214 | thus making or running the covered works for you must do so exclusively on |
| | 215 | your behalf, under your direction and control, on terms that prohibit them |
| | 216 | from making any copies of your copyrighted material outside their |
| | 217 | relationship with you. |
| | 218 | </para> |
| | 219 | <para> |
| | 220 | Conveying under any other circumstances is permitted solely under the |

| | 229 | under any applicable law fulfilling obligations under article 11 of the WIPO |
| | 230 | copyright treaty adopted on 20 December 1996, or similar laws prohibiting or |

| | 234 | When you convey a covered work, you waive any legal power to forbid |
| | 235 | circumvention of technological measures to the extent such circumvention is |
| | 236 | effected by exercising rights under this License with respect to the covered |
| | 237 | work, and you disclaim any intention to limit operation or modification of |

| 102 | | Finally, any free program is threatened constantly by software patents. |
| 103 | | We wish to avoid the danger that redistributors of a free program will |
| 104 | | individually obtain patent licenses, in effect making the program |
| 105 | | proprietary. To prevent this, we have made it clear that any patent must be |
| 106 | | licensed for everyone's free use or not licensed at all. |

| 122 | | This License applies to any program or other work which contains a notice |
| 123 | | placed by the copyright holder saying it may be distributed under the terms |
| 124 | | of this General Public License. The "Program", below, refers to any such |
| 125 | | program or work, and a <quote>work based on the Program</quote> means either |
| 126 | | the Program or any derivative work under copyright law: that is to say, a |
| 127 | | work containing the Program or a portion of it, either verbatim or with |
| 128 | | modifications and/or translated into another language. (Hereinafter, translation |

| 137 | | constitute a work based on the Program (independent of having been made by running |
| 138 | | the Program). Whether that is true depends on what the Program does. |
