| 2 | + Version 3, 29 June 2007 |
| 3 | + |
| 4 | + Copyright (C) 2007 Free Software Foundation, Inc. <https://fsf.org/> |
| 5 | + Everyone is permitted to copy and distribute verbatim copies |
| 6 | + of this license document, but changing it is not allowed. |
| 7 | + |
| 8 | + Preamble |
| 9 | + |
| 10 | + The GNU General Public License is a free, copyleft license for |
| 11 | +software and other kinds of works. |
| 12 | + |
| 13 | + The licenses for most software and other practical works are designed |
| 14 | +to take away your freedom to share and change the works. By contrast, |
| 15 | +the GNU General Public License is intended to guarantee your freedom to |
| 16 | +share and change all versions of a program--to make sure it remains free |
| 17 | +software for all its users. We, the Free Software Foundation, use the |
| 18 | +GNU General Public License for most of our software; it applies also to |
| 19 | +any other work released this way by its authors. You can apply it to |
| 20 | +your programs, too. |
| 21 | + |
| 22 | + When we speak of free software, we are referring to freedom, not |
| 23 | +price. Our General Public Licenses are designed to make sure that you |
| 24 | +have the freedom to distribute copies of free software (and charge for |
| 25 | +them if you wish), that you receive source code or can get it if you |
| 26 | +want it, that you can change the software or use pieces of it in new |
| 27 | +free programs, and that you know you can do these things. |
| 28 | + |
| 29 | + To protect your rights, we need to prevent others from denying you |
| 30 | +these rights or asking you to surrender the rights. Therefore, you have |
| 31 | +certain responsibilities if you distribute copies of the software, or if |
| 32 | +you modify it: responsibilities to respect the freedom of others. |
| 33 | + |
| 34 | + For example, if you distribute copies of such a program, whether |
| 35 | +gratis or for a fee, you must pass on to the recipients the same |
| 36 | +freedoms that you received. You must make sure that they, too, receive |
| 37 | +or can get the source code. And you must show them these terms so they |
| 38 | +know their rights. |
| 39 | + |
| 40 | + Developers that use the GNU GPL protect your rights with two steps: |
| 41 | +(1) assert copyright on the software, and (2) offer you this License |
| 42 | +giving you legal permission to copy, distribute and/or modify it. |
| 43 | + |
| 44 | + For the developers' and authors' protection, the GPL clearly explains |
| 45 | +that there is no warranty for this free software. For both users' and |
| 46 | +authors' sake, the GPL requires that modified versions be marked as |
| 47 | +changed, so that their problems will not be attributed erroneously to |
| 48 | +authors of previous versions. |
| 49 | + |
| 50 | + Some devices are designed to deny users access to install or run |
| 51 | +modified versions of the software inside them, although the manufacturer |
| 52 | +can do so. This is fundamentally incompatible with the aim of |
| 53 | +protecting users' freedom to change the software. The systematic |
| 54 | +pattern of such abuse occurs in the area of products for individuals to |
| 55 | +use, which is precisely where it is most unacceptable. Therefore, we |
| 56 | +have designed this version of the GPL to prohibit the practice for those |
| 57 | +products. If such problems arise substantially in other domains, we |
| 58 | +stand ready to extend this provision to those domains in future versions |
| 59 | +of the GPL, as needed to protect the freedom of users. |
| 60 | + |
| 61 | + Finally, every program is threatened constantly by software patents. |
| 62 | +States should not allow patents to restrict development and use of |
| 63 | +software on general-purpose computers, but in those that do, we wish to |
| 64 | +avoid the special danger that patents applied to a free program could |
| 65 | +make it effectively proprietary. To prevent this, the GPL assures that |
| 66 | +patents cannot be used to render the program non-free. |
| 67 | + |
| 68 | + The precise terms and conditions for copying, distribution and |
| 69 | +modification follow. |
| 70 | + |
| 71 | + TERMS AND CONDITIONS |
| 72 | + |
| 73 | + 0. Definitions. |
| 74 | + |
| 75 | + "This License" refers to version 3 of the GNU General Public License. |
| 76 | + |
| 77 | + "Copyright" also means copyright-like laws that apply to other kinds of |
| 78 | +works, such as semiconductor masks. |
| 79 | + |
| 80 | + "The Program" refers to any copyrightable work licensed under this |
| 81 | +License. Each licensee is addressed as "you". "Licensees" and |
| 82 | +"recipients" may be individuals or organizations. |
| 83 | + |
| 84 | + To "modify" a work means to copy from or adapt all or part of the work |
| 85 | +in a fashion requiring copyright permission, other than the making of an |
| 86 | +exact copy. The resulting work is called a "modified version" of the |
| 87 | +earlier work or a work "based on" the earlier work. |
| 88 | + |
| 89 | + A "covered work" means either the unmodified Program or a work based |
| 90 | +on the Program. |
| 91 | + |
| 92 | + To "propagate" a work means to do anything with it that, without |
| 93 | +permission, would make you directly or secondarily liable for |
| 94 | +infringement under applicable copyright law, except executing it on a |
| 95 | +computer or modifying a private copy. Propagation includes copying, |
| 96 | +distribution (with or without modification), making available to the |
| 97 | +public, and in some countries other activities as well. |
| 98 | + |
| 99 | + To "convey" a work means any kind of propagation that enables other |
| 100 | +parties to make or receive copies. Mere interaction with a user through |
| 101 | +a computer network, with no transfer of a copy, is not conveying. |
| 102 | + |
| 103 | + An interactive user interface displays "Appropriate Legal Notices" |
| 104 | +to the extent that it includes a convenient and prominently visible |
| 105 | +feature that (1) displays an appropriate copyright notice, and (2) |
| 106 | +tells the user that there is no warranty for the work (except to the |
| 107 | +extent that warranties are provided), that licensees may convey the |
| 108 | +work under this License, and how to view a copy of this License. If |
| 109 | +the interface presents a list of user commands or options, such as a |
| 110 | +menu, a prominent item in the list meets this criterion. |
| 111 | + |
| 112 | + 1. Source Code. |
| 113 | + |
| 114 | + The "source code" for a work means the preferred form of the work |
| 115 | +for making modifications to it. "Object code" means any non-source |
| 116 | +form of a work. |
| 117 | + |
| 118 | + A "Standard Interface" means an interface that either is an official |
| 119 | +standard defined by a recognized standards body, or, in the case of |
| 120 | +interfaces specified for a particular programming language, one that |
| 121 | +is widely used among developers working in that language. |
| 122 | + |
| 123 | + The "System Libraries" of an executable work include anything, other |
| 124 | +than the work as a whole, that (a) is included in the normal form of |
| 125 | +packaging a Major Component, but which is not part of that Major |
| 126 | +Component, and (b) serves only to enable use of the work with that |
| 127 | +Major Component, or to implement a Standard Interface for which an |
| 128 | +implementation is available to the public in source code form. A |
| 129 | +"Major Component", in this context, means a major essential component |
| 130 | +(kernel, window system, and so on) of the specific operating system |
| 131 | +(if any) on which the executable work runs, or a compiler used to |
| 132 | +produce the work, or an object code interpreter used to run it. |
| 133 | + |
| 134 | + The "Corresponding Source" for a work in object code form means all |
| 135 | +the source code needed to generate, install, and (for an executable |
| 136 | +work) run the object code and to modify the work, including scripts to |
| 137 | +control those activities. However, it does not include the work's |
| 138 | +System Libraries, or general-purpose tools or generally available free |
| 139 | +programs which are used unmodified in performing those activities but |
| 140 | +which are not part of the work. For example, Corresponding Source |
| 141 | +includes interface definition files associated with source files for |
| 142 | +the work, and the source code for shared libraries and dynamically |
| 143 | +linked subprograms that the work is specifically designed to require, |
| 144 | +such as by intimate data communication or control flow between those |
| 145 | +subprograms and other parts of the work. |
| 146 | + |
| 147 | + The Corresponding Source need not include anything that users |
| 148 | +can regenerate automatically from other parts of the Corresponding |
| 149 | +Source. |
| 150 | + |
| 151 | + The Corresponding Source for a work in source code form is that |
| 152 | +same work. |
| 153 | + |
| 154 | + 2. Basic Permissions. |
| 155 | + |
| 156 | + All rights granted under this License are granted for the term of |
| 157 | +copyright on the Program, and are irrevocable provided the stated |
| 158 | +conditions are met. This License explicitly affirms your unlimited |
| 159 | +permission to run the unmodified Program. The output from running a |
| 160 | +covered work is covered by this License only if the output, given its |
| 161 | +content, constitutes a covered work. This License acknowledges your |
| 162 | +rights of fair use or other equivalent, as provided by copyright law. |
| 163 | + |
| 164 | + You may make, run and propagate covered works that you do not |
| 165 | +convey, without conditions so long as your license otherwise remains |
| 166 | +in force. You may convey covered works to others for the sole purpose |
| 167 | +of having them make modifications exclusively for you, or provide you |
| 168 | +with facilities for running those works, provided that you comply with |
| 169 | +the terms of this License in conveying all material for which you do |
| 170 | +not control copyright. Those thus making or running the covered works |
| 171 | +for you must do so exclusively on your behalf, under your direction |
| 172 | +and control, on terms that prohibit them from making any copies of |
| 173 | +your copyrighted material outside their relationship with you. |
| 174 | + |
| 175 | + Conveying under any other circumstances is permitted solely under |
| 176 | +the conditions stated below. Sublicensing is not allowed; section 10 |
| 177 | +makes it unnecessary. |
| 178 | + |
| 179 | + 3. Protecting Users' Legal Rights From Anti-Circumvention Law. |
| 180 | + |
| 181 | + No covered work shall be deemed part of an effective technological |
| 182 | +measure under any applicable law fulfilling obligations under article |
| 183 | +11 of the WIPO copyright treaty adopted on 20 December 1996, or |
| 184 | +similar laws prohibiting or restricting circumvention of such |
| 185 | +measures. |
| 186 | + |
| 187 | + When you convey a covered work, you waive any legal power to forbid |
| 188 | +circumvention of technological measures to the extent such circumvention |
| 189 | +is effected by exercising rights under this License with respect to |
| 190 | +the covered work, and you disclaim any intention to limit operation or |
| 191 | +modification of the work as a means of enforcing, against the work's |
| 192 | +users, your or third parties' legal rights to forbid circumvention of |
| 193 | +technological measures. |
| 194 | + |
| 195 | + 4. Conveying Verbatim Copies. |
| 196 | + |
| 197 | + You may convey verbatim copies of the Program's source code as you |
| 198 | +receive it, in any medium, provided that you conspicuously and |
| 199 | +appropriately publish on each copy an appropriate copyright notice; |
| 200 | +keep intact all notices stating that this License and any |
| 201 | +non-permissive terms added in accord with section 7 apply to the code; |
| 202 | +keep intact all notices of the absence of any warranty; and give all |
| 203 | +recipients a copy of this License along with the Program. |
| 204 | + |
| 205 | + You may charge any price or no price for each copy that you convey, |
| 206 | +and you may offer support or warranty protection for a fee. |
| 207 | + |
| 208 | + 5. Conveying Modified Source Versions. |
| 209 | + |
| 210 | + You may convey a work based on the Program, or the modifications to |
| 211 | +produce it from the Program, in the form of source code under the |
| 212 | +terms of section 4, provided that you also meet all of these conditions: |
| 213 | + |
| 214 | + a) The work must carry prominent notices stating that you modified |
| 215 | + it, and giving a relevant date. |
| 216 | + |
| 217 | + b) The work must carry prominent notices stating that it is |
| 218 | + released under this License and any conditions added under section |
| 219 | + 7. This requirement modifies the requirement in section 4 to |
| 220 | + "keep intact all notices". |
| 221 | + |
| 222 | + c) You must license the entire work, as a whole, under this |
| 223 | + License to anyone who comes into possession of a copy. This |
| 224 | + License will therefore apply, along with any applicable section 7 |
| 225 | + additional terms, to the whole of the work, and all its parts, |
| 226 | + regardless of how they are packaged. This License gives no |
| 227 | + permission to license the work in any other way, but it does not |
| 228 | + invalidate such permission if you have separately received it. |
| 229 | + |
| 230 | + d) If the work has interactive user interfaces, each must display |
| 231 | + Appropriate Legal Notices; however, if the Program has interactive |
| 232 | + interfaces that do not display Appropriate Legal Notices, your |
| 233 | + work need not make them do so. |
