| 11 | GNU GENERAL PUBLIC LICENSE
|

| 12 | Version 3, 29 June 2007
|
|---|
| 13 |
|
|---|
| 14 | Copyright (C) 2007 Free Software Foundation, Inc. <http://fsf.org/>
|
|---|
| 15 | Everyone is permitted to copy and distribute verbatim copies
|
|---|
| 16 | of this license document, but changing it is not allowed.
|
|---|
| 17 |
|
|---|
| 18 | Preamble
|
|---|
| 19 |
|
|---|
| 20 | The GNU General Public License is a free, copyleft license for
|
|---|
| 21 | software and other kinds of works.
|
|---|
| 22 |
|
|---|
| 23 | The licenses for most software and other practical works are designed
|
|---|
| 24 | to take away your freedom to share and change the works. By contrast,
|
|---|
| 25 | the GNU General Public License is intended to guarantee your freedom to
|
|---|
| 26 | share and change all versions of a program--to make sure it remains free
|
|---|
| 27 | software for all its users. We, the Free Software Foundation, use the
|
|---|
| 28 | GNU General Public License for most of our software; it applies also to
|
|---|
| 29 | any other work released this way by its authors. You can apply it to
|
|---|
| 30 | your programs, too.
|
|---|
| 31 |
|
|---|
| 32 | When we speak of free software, we are referring to freedom, not
|
|---|
| 33 | price. Our General Public Licenses are designed to make sure that you
|
|---|
| 34 | have the freedom to distribute copies of free software (and charge for
|
|---|
| 35 | them if you wish), that you receive source code or can get it if you
|
|---|
| 36 | want it, that you can change the software or use pieces of it in new
|
|---|
| 37 | free programs, and that you know you can do these things.
|
|---|
| 38 |
|
|---|
| 39 | To protect your rights, we need to prevent others from denying you
|
|---|
| 40 | these rights or asking you to surrender the rights. Therefore, you have
|
|---|
| 41 | certain responsibilities if you distribute copies of the software, or if
|
|---|
| 42 | you modify it: responsibilities to respect the freedom of others.
|
|---|
| 43 |
|
|---|
| 44 | For example, if you distribute copies of such a program, whether
|
|---|
| 45 | gratis or for a fee, you must pass on to the recipients the same
|
|---|
| 46 | freedoms that you received. You must make sure that they, too, receive
|
|---|
| 47 | or can get the source code. And you must show them these terms so they
|
|---|
| 48 | know their rights.
|
|---|
| 49 |
|
|---|
| 50 | Developers that use the GNU GPL protect your rights with two steps:
|
|---|
| 51 | (1) assert copyright on the software, and (2) offer you this License
|
|---|
| 52 | giving you legal permission to copy, distribute and/or modify it.
|
|---|
| 53 |
|
|---|
| 54 | For the developers' and authors' protection, the GPL clearly explains
|
|---|
| 55 | that there is no warranty for this free software. For both users' and
|
|---|
| 56 | authors' sake, the GPL requires that modified versions be marked as
|
|---|
| 57 | changed, so that their problems will not be attributed erroneously to
|
|---|
| 58 | authors of previous versions.
|
|---|
| 59 |
|
|---|
| 60 | Some devices are designed to deny users access to install or run
|
|---|
| 61 | modified versions of the software inside them, although the manufacturer
|
|---|
| 62 | can do so. This is fundamentally incompatible with the aim of
|
|---|
| 63 | protecting users' freedom to change the software. The systematic
|
|---|
| 64 | pattern of such abuse occurs in the area of products for individuals to
|
|---|
| 65 | use, which is precisely where it is most unacceptable. Therefore, we
|
|---|
| 66 | have designed this version of the GPL to prohibit the practice for those
|
|---|
| 67 | products. If such problems arise substantially in other domains, we
|
|---|
| 68 | stand ready to extend this provision to those domains in future versions
|
|---|
| 69 | of the GPL, as needed to protect the freedom of users.
|
|---|
| 70 |
|
|---|
| 71 | Finally, every program is threatened constantly by software patents.
|
|---|
| 72 | States should not allow patents to restrict development and use of
|
|---|
| 73 | software on general-purpose computers, but in those that do, we wish to
|
|---|
| 74 | avoid the special danger that patents applied to a free program could
|
|---|
| 75 | make it effectively proprietary. To prevent this, the GPL assures that
|
|---|
| 76 | patents cannot be used to render the program non-free.
|
|---|
| 77 |
|
|---|
| 78 | The precise terms and conditions for copying, distribution and
|
|---|
| 79 | modification follow.
|
|---|
| 80 |
|
|---|
| 81 | TERMS AND CONDITIONS
|
|---|
| 82 |
|
|---|
| 83 | 0. Definitions.
|
|---|
| 84 |
|
|---|
| 85 | "This License" refers to version 3 of the GNU General Public License.
|
|---|
| 86 |
|
|---|
| 87 | "Copyright" also means copyright-like laws that apply to other kinds of
|
|---|
| 88 | works, such as semiconductor masks.
|
|---|
| 89 |
|
|---|
| 90 | "The Program" refers to any copyrightable work licensed under this
|
|---|
| 91 | License. Each licensee is addressed as "you". "Licensees" and
|
|---|
| 92 | "recipients" may be individuals or organizations.
|
|---|
| 93 |
|
|---|
| 94 | To "modify" a work means to copy from or adapt all or part of the work
|
|---|
| 95 | in a fashion requiring copyright permission, other than the making of an
|
|---|
| 96 | exact copy. The resulting work is called a "modified version" of the
|
|---|
| 97 | earlier work or a work "based on" the earlier work.
|
|---|
| 98 |
|
|---|
| 99 | A "covered work" means either the unmodified Program or a work based
|
|---|
| 100 | on the Program.
|
|---|
| 101 |
|
|---|
| 102 | To "propagate" a work means to do anything with it that, without
|
|---|
| 103 | permission, would make you directly or secondarily liable for
|
|---|
| 104 | infringement under applicable copyright law, except executing it on a
|
|---|
| 105 | computer or modifying a private copy. Propagation includes copying,
|
|---|
| 106 | distribution (with or without modification), making available to the
|
|---|
| 107 | public, and in some countries other activities as well.
|
|---|
| 108 |
|
|---|
| 109 | To "convey" a work means any kind of propagation that enables other
|
|---|
| 110 | parties to make or receive copies. Mere interaction with a user through
|
|---|
| 111 | a computer network, with no transfer of a copy, is not conveying.
|
|---|
| 112 |
|
|---|
| 113 | An interactive user interface displays "Appropriate Legal Notices"
|
|---|
| 114 | to the extent that it includes a convenient and prominently visible
|
|---|
| 115 | feature that (1) displays an appropriate copyright notice, and (2)
|
|---|
| 116 | tells the user that there is no warranty for the work (except to the
|
|---|
| 117 | extent that warranties are provided), that licensees may convey the
|
|---|
| 118 | work under this License, and how to view a copy of this License. If
|
|---|
| 119 | the interface presents a list of user commands or options, such as a
|
|---|
| 120 | menu, a prominent item in the list meets this criterion.
|
|---|
| 121 |
|
|---|
| 122 | 1. Source Code.
|
|---|
| 123 |
|
|---|
| 124 | The "source code" for a work means the preferred form of the work
|
|---|
| 125 | for making modifications to it. "Object code" means any non-source
|
|---|
| 126 | form of a work.
|
|---|
| 127 |
|
|---|
| 128 | A "Standard Interface" means an interface that either is an official
|
|---|
| 129 | standard defined by a recognized standards body, or, in the case of
|
|---|
| 130 | interfaces specified for a particular programming language, one that
|
|---|
| 131 | is widely used among developers working in that language.
|
|---|
| 132 |
|
|---|
| 133 | The "System Libraries" of an executable work include anything, other
|
|---|
| 134 | than the work as a whole, that (a) is included in the normal form of
|
|---|
| 135 | packaging a Major Component, but which is not part of that Major
|
|---|
| 136 | Component, and (b) serves only to enable use of the work with that
|
|---|
| 137 | Major Component, or to implement a Standard Interface for which an
|
|---|
| 138 | implementation is available to the public in source code form. A
|
|---|
| 139 | "Major Component", in this context, means a major essential component
|
|---|
| 140 | (kernel, window system, and so on) of the specific operating system
|
|---|
| 141 | (if any) on which the executable work runs, or a compiler used to
|
|---|
| 142 | produce the work, or an object code interpreter used to run it.
|
|---|
| 143 |
|
|---|
| 144 | The "Corresponding Source" for a work in object code form means all
|
|---|
| 145 | the source code needed to generate, install, and (for an executable
|
|---|
| 146 | work) run the object code and to modify the work, including scripts to
|
|---|
| 147 | control those activities. However, it does not include the work's
|
|---|
| 148 | System Libraries, or general-purpose tools or generally available free
|
|---|
| 149 | programs which are used unmodified in performing those activities but
|
|---|
| 150 | which are not part of the work. For example, Corresponding Source
|
|---|
| 151 | includes interface definition files associated with source files for
|
|---|
| 152 | the work, and the source code for shared libraries and dynamically
|
|---|
| 153 | linked subprograms that the work is specifically designed to require,
|
|---|
| 154 | such as by intimate data communication or control flow between those
|
|---|
| 155 | subprograms and other parts of the work.
|
|---|
| 156 |
|
|---|
| 157 | The Corresponding Source need not include anything that users
|
|---|
| 158 | can regenerate automatically from other parts of the Corresponding
|
|---|
| 159 | Source.
|
|---|
| 160 |
|
|---|
| 161 | The Corresponding Source for a work in source code form is that
|
|---|
| 162 | same work.
|
|---|
| 163 |
|
|---|
| 164 | 2. Basic Permissions.
|
|---|
| 165 |
|
|---|
| 166 | All rights granted under this License are granted for the term of
|
|---|
| 167 | copyright on the Program, and are irrevocable provided the stated
|
|---|
| 168 | conditions are met. This License explicitly affirms your unlimited
|
|---|
| 169 | permission to run the unmodified Program. The output from running a
|
|---|
| 170 | covered work is covered by this License only if the output, given its
|
|---|
| 171 | content, constitutes a covered work. This License acknowledges your
|
|---|
| 172 | rights of fair use or other equivalent, as provided by copyright law.
|
|---|
| 173 |
|
|---|
| 174 | You may make, run and propagate covered works that you do not
|
|---|
| 175 | convey, without conditions so long as your license otherwise remains
|
|---|
| 176 | in force. You may convey covered works to others for the sole purpose
|
|---|
| 177 | of having them make modifications exclusively for you, or provide you
|
|---|
| 178 | with facilities for running those works, provided that you comply with
|
|---|
| 179 | the terms of this License in conveying all material for which you do
|
|---|
| 180 | not control copyright. Those thus making or running the covered works
|
|---|
| 181 | for you must do so exclusively on your behalf, under your direction
|
|---|
| 182 | and control, on terms that prohibit them from making any copies of
|
|---|
| 183 | your copyrighted material outside their relationship with you.
|
|---|
| 184 |
|
|---|
| 185 | Conveying under any other circumstances is permitted solely under
|
|---|
| 186 | the conditions stated below. Sublicensing is not allowed; section 10
|
|---|
| 187 | makes it unnecessary.
|
|---|
| 188 |
|
|---|
| 189 | 3. Protecting Users' Legal Rights From Anti-Circumvention Law.
|
|---|
| 190 |
|
|---|
| 191 | No covered work shall be deemed part of an effective technological
|
|---|
| 192 | measure under any applicable law fulfilling obligations under article
|
|---|
| 193 | 11 of the WIPO copyright treaty adopted on 20 December 1996, or
|
|---|
| 194 | similar laws prohibiting or restricting circumvention of such
|
|---|
| 195 | measures.
|
|---|
| 196 |
|
|---|
| 197 | When you convey a covered work, you waive any legal power to forbid
|
|---|
| 198 | circumvention of technological measures to the extent such circumvention
|
|---|
| 199 | is effected by exercising rights under this License with respect to
|
|---|
| 200 | the covered work, and you disclaim any intention to limit operation or
|
|---|
| 201 | modification of the work as a means of enforcing, against the work's
|
|---|
| 202 | users, your or third parties' legal rights to forbid circumvention of
|
|---|
| 203 | technological measures.
|
|---|
| 204 |
|
|---|
| 205 | 4. Conveying Verbatim Copies.
|
|---|
| 206 |
|
|---|
| 207 | You may convey verbatim copies of the Program's source code as you
|
|---|
| 208 | receive it, in any medium, provided that you conspicuously and
|
|---|
| 209 | appropriately publish on each copy an appropriate copyright notice;
|
|---|
| 210 | keep intact all notices stating that this License and any
|
|---|
| 211 | non-permissive terms added in accord with section 7 apply to the code;
|
|---|
| 212 | keep intact all notices of the absence of any warranty; and give all
|
|---|
| 213 | recipients a copy of this License along with the Program.
|
|---|
| 214 |
|
|---|
| 215 | You may charge any price or no price for each copy that you convey,
|
|---|
| 216 | and you may offer support or warranty protection for a fee.
|
|---|
| 217 |
|
|---|
| 218 | 5. Conveying Modified Source Versions.
|
|---|
| 219 |
|
|---|
| 220 | You may convey a work based on the Program, or the modifications to
|
|---|
| 221 | produce it from the Program, in the form of source code under the
|
|---|
| 222 | terms of section 4, provided that you also meet all of these conditions:
|
|---|
| 223 |
|
|---|
| 224 | a) The work must carry prominent notices stating that you modified
|
|---|
| 225 | it, and giving a relevant date.
|
|---|
| 226 |
|
|---|
| 227 | b) The work must carry prominent notices stating that it is
|
|---|
| 228 | released under this License and any conditions added under section
|
|---|
| 229 | 7. This requirement modifies the requirement in section 4 to
|
|---|
| 230 | "keep intact all notices".
|
|---|
| 231 |
|
|---|
| 232 | c) You must license the entire work, as a whole, under this
|
|---|
| 233 | License to anyone who comes into possession of a copy. This
|
|---|
| 234 | License will therefore apply, along with any applicable section 7
|
|---|
| 235 | additional terms, to the whole of the work, and all its parts,
|
|---|
| 236 | regardless of how they are packaged. This License gives no
|
|---|
| 237 | permission to license the work in any other way, but it does not
|
|---|
| 238 | invalidate such permission if you have separately received it.
|
|---|
| 239 |
|
|---|
| 240 | d) If the work has interactive user interfaces, each must display
|
|---|
| 241 | Appropriate Legal Notices; however, if the Program has interactive
|
|---|
| 242 | interfaces that do not display Appropriate Legal Notices, your
|
|---|
| 243 | work need not make them do so.
|
|---|
| 244 |
|
|---|
| 245 | A compilation of a covered work with other separate and independent
|
|---|
| 246 | works, which are not by their nature extensions of the covered work,
|
|---|
| 247 | and which are not combined with it such as to form a larger program,
|
|---|
| 248 | in or on a volume of a storage or distribution medium, is called an
|
|---|
| 249 | "aggregate" if the compilation and its resulting copyright are not
|
|---|
| 250 | used to limit the access or legal rights of the compilation's users
|
|---|
| 251 | beyond what the individual works permit. Inclusion of a covered work
|
|---|
| 252 | in an aggregate does not cause this License to apply to the other
|
|---|
| 253 | parts of the aggregate.
|
|---|
| 254 |
|
|---|
| 255 | 6. Conveying Non-Source Forms.
|
|---|
| 256 |
|
|---|
| 257 | You may convey a covered work in object code form under the terms
|
|---|
| 258 | of sections 4 and 5, provided that you also convey the
|
|---|
| 259 | machine-readable Corresponding Source under the terms of this License,
|
|---|
| 260 | in one of these ways:
|
|---|
| 261 |
|
|---|
| 262 | a) Convey the object code in, or embodied in, a physical product
|
|---|
| 263 | (including a physical distribution medium), accompanied by the
|
|---|
| 264 | Corresponding Source fixed on a durable physical medium
|
|---|
| 265 | customarily used for software interchange.
|
|---|
| 266 |
|
|---|
| 267 | b) Convey the object code in, or embodied in, a physical product
|
|---|
| 268 | (including a physical distribution medium), accompanied by a
|
|---|
| 269 | written offer, valid for at least three years and valid for as
|
|---|
| 270 | long as you offer spare parts or customer support for that product
|
|---|
| 271 | model, to give anyone who possesses the object code either (1) a
|
|---|
| 272 | copy of the Corresponding Source for all the software in the
|
|---|
| 273 | product that is covered by this License, on a durable physical
|
|---|
| 274 | medium customarily used for software interchange, for a price no
|
|---|
| 275 | more than your reasonable cost of physically performing this
|
|---|
| 276 | conveying of source, or (2) access to copy the
|
|---|
| 277 | Corresponding Source from a network server at no charge.
|
|---|
| 278 |
|
|---|
| 279 | c) Convey individual copies of the object code with a copy of the
|
|---|
| 280 | written offer to provide the Corresponding Source. This
|
|---|
| 281 | alternative is allowed only occasionally and noncommercially, and
|
|---|
| 282 | only if you received the object code with such an offer, in accord
|
|---|
| 283 | with subsection 6b.
|
|---|
| 284 |
|
|---|
| 285 | d) Convey the object code by offering access from a designated
|
|---|
| 286 | place (gratis or for a charge), and offer equivalent access to the
|
|---|
| 287 | Corresponding Source in the same way through the same place at no
|
|---|
| 288 | further charge. You need not require recipients to copy the
|
|---|
| 289 | Corresponding Source along with the object code. If the place to
|
|---|
| 290 | copy the object code is a network server, the Corresponding Source
|
|---|
| 291 | may be on a different server (operated by you or a third party)
|
|---|
| 292 | that supports equivalent copying facilities, provided you maintain
|
|---|
| 293 | clear directions next to the object code saying where to find the
|
|---|
| 294 | Corresponding Source. Regardless of what server hosts the
|
|---|
| 295 | Corresponding Source, you remain obligated to ensure that it is
|
|---|
| 296 | available for as long as needed to satisfy these requirements.
|
|---|
| 297 |
|
|---|
| 298 | e) Convey the object code using peer-to-peer transmission, provided
|
|---|
| 299 | you inform other peers where the object code and Corresponding
|
|---|
| 300 | Source of the work are being offered to the general public at no
|
|---|
| 301 | charge under subsection 6d.
|
|---|
| 302 |
|
|---|
| 303 | A separable portion of the object code, whose source code is excluded
|
|---|
| 304 | from the Corresponding Source as a System Library, need not be
|
|---|
| 305 | included in conveying the object code work.
|
|---|
| 306 |
|
|---|
| 307 | A "User Product" is either (1) a "consumer product", which means any
|
|---|
| 308 | tangible personal property which is normally used for personal, family,
|
|---|
| 309 | or household purposes, or (2) anything designed or sold for incorporation
|
|---|
| 310 | into a dwelling. In determining whether a product is a consumer product,
|
|---|
| 311 | doubtful cases shall be resolved in favor of coverage. For a particular
|
|---|
| 312 | product received by a particular user, "normally used" refers to a
|
|---|
| 313 | typical or common use of that class of product, regardless of the status
|
|---|
| 314 | of the particular user or of the way in which the particular user
|
|---|
| 315 | actually uses, or expects or is expected to use, the product. A product
|
|---|
| 316 | is a consumer product regardless of whether the product has substantial
|
|---|
| 317 | commercial, industrial or non-consumer uses, unless such uses represent
|
|---|
| 318 | the only significant mode of use of the product.
|
|---|
| 319 |
|
|---|
| 320 | "Installation Information" for a User Product means any methods,
|
|---|
| 321 | procedures, authorization keys, or other information required to install
|
|---|
| 322 | and execute modified versions of a covered work in that User Product from
|
|---|
| 323 | a modified version of its Corresponding Source. The information must
|
|---|
| 324 | suffice to ensure that the continued functioning of the modified object
|
|---|
| 325 | code is in no case prevented or interfered with solely because
|
|---|
| 326 | modification has been made.
|
|---|
| 327 |
|
|---|
| 328 | If you convey an object code work under this section in, or with, or
|
|---|
| 329 | specifically for use in, a User Product, and the conveying occurs as
|
|---|
| 330 | part of a transaction in which the right of possession and use of the
|
|---|
| 331 | User Product is transferred to the recipient in perpetuity or for a
|
|---|
| 332 | fixed term (regardless of how the transaction is characterized), the
|
|---|
| 333 | Corresponding Source conveyed under this section must be accompanied
|
|---|
| 334 | by the Installation Information. But this requirement does not apply
|
|---|
| 335 | if neither you nor any third party retains the ability to install
