By contrast, the 30 <acronym>GNU</acronym> General Public License is intended to guarantee your 31 freedom to share and change all versions of a program—to make sure it 32 remains free software for all its users. We, the Free Software Foundation, 33 use the <acronym>GNU</acronym> General Public License for most of our 34 software; it applies also to any other work released this way by its 35 authors. You can apply it to your programs, too. 36 </para> 37 <para> 38 When we speak of free software, we are referring to freedom, not price. Our 39 General Public Licenses are designed to make sure that you have the freedom 40 to distribute copies of free software (and charge for them if you wish), 41 that you receive source code or can get it if you want it, that you can 42 change the software or use pieces of it in new free programs, and that you 43 know you can do these things. 44 </para> 45 <para> 46 To protect your rights, we need to prevent others from denying you these 47 rights or asking you to surrender the rights. Therefore, you have certain 48 responsibilities if you distribute copies of the software, or if you modify 49 it: responsibilities to respect the freedom of others. 50 </para> 51 <para> 52 For example, if you distribute copies of such a program, whether gratis or 53 for a fee, you must pass on to the recipients the same freedoms that you 54 received. You must make sure that they, too, receive or can get the source 55 code. And you must show them these terms so they know their rights. 56 </para> 57 <para> 58 Developers that use the <acronym>GNU</acronym> <acronym>GPL</acronym> 59 protect your rights with two steps: (1) assert copyright on the software, 60 and (2) offer you this License giving you legal permission to copy, 61 distribute and/or modify it. 62 </para> 63 <para> 64 For the developers’ and authors’ protection, the 65 <acronym>GPL</acronym> clearly explains that there is no warranty for this 66 free software. For both users’ and authors’ sake, the 67 <acronym>GPL</acronym> requires that modified versions be marked as changed, 68 so that their problems will not be attributed erroneously to authors of 69 previous versions. 70 </para> 71 <para> 72 Some devices are designed to deny users access to install or run modified 73 versions of the software inside them, although the manufacturer can do so. 74 This is fundamentally incompatible with the aim of protecting users’ 75 freedom to change the software. The systematic pattern of such abuse occurs 76 in the area of products for individuals to use, which is precisely where it 77 is most unacceptable. Therefore, we have designed this version of the 78 <acronym>GPL</acronym> to prohibit the practice for those products. If such 79 problems arise substantially in other domains, we stand ready to extend this 80 provision to those domains in future versions of the <acronym>GPL</acronym>, 81 as needed to protect the freedom of users. 82 </para> 83 <para> 84 Finally, every program is threatened constantly by software patents. States 85 should not allow patents to restrict development and use of software on 86 general-purpose computers, but in those that do, we wish to avoid the 87 special danger that patents applied to a free program could make it 88 effectively proprietary. To prevent this, the <acronym>GPL</acronym> 89 assures that patents cannot be used to render the program non-free. 90 </para> 91 <para> 92 The precise terms and conditions for copying, distribution and modification 93 follow. 94 </para> 95 <bridgehead> 96 TERMS AND CONDITIONS 97 </bridgehead> 98 <bridgehead id="gpl-3-definitions" renderas="sect1"> 99 0. Definitions. 100 </bridgehead> 101 <para> 102 “This License” refers to version 3 of the <acronym>GNU</acronym> 103 General Public License. 104 </para> 105 <para> 106 “Copyright” also means copyright-like laws that apply to other 107 kinds of works, such as semiconductor masks. 108 </para> 109 <para> 110 “The Program” refers to any copyrightable work licensed under 111 this License. Each licensee is addressed as “you”. 112 “Licensees” and “recipients” may be individuals or 113 organizations. 114 </para> 115 <para> 116 To “modify” a work means to copy from or adapt all or part of 117 the work in a fashion requiring copyright permission, other than the making 118 of an exact copy. The resulting work is called a “modified 119 version” of the earlier work or a work “based on” the 120 earlier work. 121 </para> 122 <para> 123 A “covered work” means either the unmodified Program or a work 124 based on the Program. 125 </para> 126 <para> 127 To “propagate” a work means to do anything with it that, without 128 permission, would make you directly or secondarily liable for infringement 129 under applicable copyright law, except executing it on a computer or 130 modifying a private copy. Propagation includes copying, distribution (with 131 or without modification), making available to the public, and in some 132 countries other activities as well. 133 </para> 134 <para> 135 To “convey” a work means any kind of propagation that enables 136 other parties to make or receive copies. Mere interaction with a user 137 through a computer network, with no transfer of a copy, is not conveying. 138 </para> 139 <para> 140 An interactive user interface displays “Appropriate Legal 141 Notices” to the extent that it includes a convenient and prominently 142 visible feature that (1) displays an appropriate copyright notice, and (2) 143 tells the user that there is no warranty for the work (except to the extent 144 that warranties are provided), that licensees may convey the work under this 145 License, and how to view a copy of this License. If the interface presents 146 a list of user commands or options, such as a menu, a prominent item in the 147 list meets this criterion. 148 </para> 149 <bridgehead id="SourceCode" renderas="sect1"> 150 1. Source Code. 151 </bridgehead> 152 <para> 153 The “source code” for a work means the preferred form of the 154 work for making modifications to it. “Object code” means any 155 non-source form of a work. 156 </para> 157 <para> 158 A “Standard Interface” means an interface that either is an 159 official standard defined by a recognized standards body, or, in the case of 160 interfaces specified for a particular programming language, one that is 161 widely used among developers working in that language. 162 </para> 163 <para> 164 The “System Libraries” of an executable work include anything, 165 other than the work as a whole, that (a) is included in the normal form of 166 packaging a Major Component, but which is not part of that Major Component, 167 and (b) serves only to enable use of the work with that Major Component, or 168 to implement a Standard Interface for which an implementation is available 169 to the public in source code form. A “Major Component”, in this 170 context, means a major essential component (kernel, window system, and so 171 on) of the specific operating system (if any) on which the executable work 172 runs, or a compiler used to produce the work, or an object code interpreter 173 used to run it. 174 </para> 175 <para> 176 The “Corresponding Source” for a work in object code form means 177 all the source code needed to generate, install, and (for an executable 178 work) run the object code and to modify the work, including scripts to 179 control those activities. However, it does not include the work’s 180 System Libraries, or general-purpose tools or generally available free 181 programs which are used unmodified in performing those activities but which 182 are not part of the work. For example, Corresponding Source includes 183 interface definition files associated with source files for the work, and 184 the source code for shared libraries and dynamically linked subprograms that 185 the work is specifically designed to require, such as by intimate data 186 communication or control flow between those subprograms and other parts of 187 the work. 188 </para> 189 <para> 190 The Corresponding Source need not include anything that users can regenerate 191 automatically from other parts of the Corresponding Source. 192 </para> 193 <para> 194 The Corresponding Source for a work in source code form is that same work. 195 </para> 196 <bridgehead id="BasicPermissions" renderas="sect1"> 197 2.

To “grant” such a patent 626 license to a party means to make such an agreement or commitment not to 627 enforce a patent against the party. 628 </para> 629 <para> 630 If you convey a covered work, knowingly relying on a patent license, and the 631 Corresponding Source of the work is not available for anyone to copy, free 632 of charge and under the terms of this License, through a publicly available 633 network server or other readily accessible means, then you must either (1) 634 cause the Corresponding Source to be so available, or (2) arrange to deprive 635 yourself of the benefit of the patent license for this particular work, or 636 (3) arrange, in a manner consistent with the requirements of this License, 637 to extend the patent license to downstream recipients. “Knowingly 638 relying” means you have actual knowledge that, but for the patent 639 license, your conveying the covered work in a country, or your 640 recipient’s use of the covered work in a country, would infringe one 641 or more identifiable patents in that country that you have reason to believe 642 are valid. 643 </para> 644 <para> 645 If, pursuant to or in connection with a single transaction or arrangement, 646 you convey, or propagate by procuring conveyance of, a covered work, and 647 grant a patent license to some of the parties receiving the covered work 648 authorizing them to use, propagate, modify or convey a specific copy of the 649 covered work, then the patent license you grant is automatically extended to 650 all recipients of the covered work and works based on it. 651 </para> 652 <para> 653 A patent license is “discriminatory” if it does not include 654 within the scope of its coverage, prohibits the exercise of, or is 655 conditioned on the non-exercise of one or more of the rights that are 656 specifically granted under this License. You may not convey a covered work 657 if you are a party to an arrangement with a third party that is in the 658 business of distributing software, under which you make payment to the third 659 party based on the extent of your activity of conveying the work, and under 660 which the third party grants, to any of the parties who would receive the 661 covered work from you, a discriminatory patent license (a) in connection 662 with copies of the covered work conveyed by you (or copies made from those 663 copies), or (b) primarily for and in connection with specific products or 664 compilations that contain the covered work, unless you entered into that 665 arrangement, or that patent license was granted, prior to 28 March 2007. 666 </para> 667 <para> 668 Nothing in this License shall be construed as excluding or limiting any 669 implied license or other defenses to infringement that may otherwise be 670 available to you under applicable patent law. 671 </para> 672 <bridgehead id="NoSurrender" renderas="sect1"> 673 12.

If you cannot convey a 679 covered work so as to satisfy simultaneously your obligations under this 680 License and any other pertinent obligations, then as a consequence you may 681 not convey it at all. For example, if you agree to terms that obligate you 682 to collect a royalty for further conveying from those to whom you convey the 683 Program, the only way you could satisfy both those terms and this License 684 would be to refrain entirely from conveying the Program. 685 </para> 686 <bridgehead id="UsedWithAGPL" renderas="sect1"> 687 13.
