|

|
| paul@0 | 4 | Copyright (C) 2007 Free Software Foundation, Inc. <http://fsf.org/>
|
| paul@0 | 5 | Everyone is permitted to copy and distribute verbatim copies
|
| paul@0 | 6 | of this license document, but changing it is not allowed.
|
| paul@0 | 7 |
|
| paul@0 | 8 | Preamble
|
| paul@0 | 9 |
|
| paul@0 | 10 | The GNU General Public License is a free, copyleft license for
|
| paul@0 | 11 | software and other kinds of works.
|
| paul@0 | 12 |
|
| paul@0 | 13 | The licenses for most software and other practical works are designed
|
| paul@0 | 14 | to take away your freedom to share and change the works. By contrast,
|
| paul@0 | 15 | the GNU General Public License is intended to guarantee your freedom to
|
| paul@0 | 16 | share and change all versions of a program--to make sure it remains free
|
| paul@0 | 17 | software for all its users. We, the Free Software Foundation, use the
|
| paul@0 | 18 | GNU General Public License for most of our software; it applies also to
|
| paul@0 | 19 | any other work released this way by its authors. You can apply it to
|
| paul@0 | 20 | your programs, too.
|
| paul@0 | 21 |
|
| paul@0 | 22 | When we speak of free software, we are referring to freedom, not
|
| paul@0 | 23 | price. Our General Public Licenses are designed to make sure that you
|
| paul@0 | 24 | have the freedom to distribute copies of free software (and charge for
|
| paul@0 | 25 | them if you wish), that you receive source code or can get it if you
|
| paul@0 | 26 | want it, that you can change the software or use pieces of it in new
|
| paul@0 | 27 | free programs, and that you know you can do these things.
|
| paul@0 | 28 |
|
| paul@0 | 29 | To protect your rights, we need to prevent others from denying you
|
| paul@0 | 30 | these rights or asking you to surrender the rights. Therefore, you have
|
| paul@0 | 31 | certain responsibilities if you distribute copies of the software, or if
|
| paul@0 | 32 | you modify it: responsibilities to respect the freedom of others.
|
| paul@0 | 33 |
|
| paul@0 | 34 | For example, if you distribute copies of such a program, whether
|
| paul@0 | 35 | gratis or for a fee, you must pass on to the recipients the same
|
| paul@0 | 36 | freedoms that you received. You must make sure that they, too, receive
|
| paul@0 | 37 | or can get the source code. And you must show them these terms so they
|
| paul@0 | 38 | know their rights.
|
| paul@0 | 39 |
|
| paul@0 | 40 | Developers that use the GNU GPL protect your rights with two steps:
|
| paul@0 | 41 | (1) assert copyright on the software, and (2) offer you this License
|
| paul@0 | 42 | giving you legal permission to copy, distribute and/or modify it.
|
| paul@0 | 43 |
|
| paul@0 | 44 | For the developers' and authors' protection, the GPL clearly explains
|
| paul@0 | 45 | that there is no warranty for this free software. For both users' and
|
| paul@0 | 46 | authors' sake, the GPL requires that modified versions be marked as
|
| paul@0 | 47 | changed, so that their problems will not be attributed erroneously to
|
| paul@0 | 48 | authors of previous versions.
|
| paul@0 | 49 |
|
| paul@0 | 50 | Some devices are designed to deny users access to install or run
|
| paul@0 | 51 | modified versions of the software inside them, although the manufacturer
|
| paul@0 | 52 | can do so. This is fundamentally incompatible with the aim of
|
| paul@0 | 53 | protecting users' freedom to change the software. The systematic
|
| paul@0 | 54 | pattern of such abuse occurs in the area of products for individuals to
|
| paul@0 | 55 | use, which is precisely where it is most unacceptable. Therefore, we
|
| paul@0 | 56 | have designed this version of the GPL to prohibit the practice for those
|
| paul@0 | 57 | products. If such problems arise substantially in other domains, we
|
| paul@0 | 58 | stand ready to extend this provision to those domains in future versions
|
| paul@0 | 59 | of the GPL, as needed to protect the freedom of users.
|
| paul@0 | 60 |
|
| paul@0 | 61 | Finally, every program is threatened constantly by software patents.
|
| paul@0 | 62 | States should not allow patents to restrict development and use of
|
| paul@0 | 63 | software on general-purpose computers, but in those that do, we wish to
|
| paul@0 | 64 | avoid the special danger that patents applied to a free program could
|
| paul@0 | 65 | make it effectively proprietary. To prevent this, the GPL assures that
|
| paul@0 | 66 | patents cannot be used to render the program non-free.
|
| paul@0 | 67 |
|
| paul@0 | 68 | The precise terms and conditions for copying, distribution and
|
| paul@0 | 69 | modification follow.
|
| paul@0 | 70 |
|
| paul@0 | 71 | TERMS AND CONDITIONS
|
| paul@0 | 72 |
|
| paul@0 | 73 | 0. Definitions.
|
| paul@0 | 74 |
|
| paul@0 | 75 | "This License" refers to version 3 of the GNU General Public License.
|
| paul@0 | 76 |
|
| paul@0 | 77 | "Copyright" also means copyright-like laws that apply to other kinds of
|
| paul@0 | 78 | works, such as semiconductor masks.
|
| paul@0 | 79 |
|
| paul@0 | 80 | "The Program" refers to any copyrightable work licensed under this
|
| paul@0 | 81 | License. Each licensee is addressed as "you". "Licensees" and
|
| paul@0 | 82 | "recipients" may be individuals or organizations.
|
| paul@0 | 83 |
|
| paul@0 | 84 | To "modify" a work means to copy from or adapt all or part of the work
|
| paul@0 | 85 | in a fashion requiring copyright permission, other than the making of an
|
| paul@0 | 86 | exact copy. The resulting work is called a "modified version" of the
|
| paul@0 | 87 | earlier work or a work "based on" the earlier work.
|
| paul@0 | 88 |
|
| paul@0 | 89 | A "covered work" means either the unmodified Program or a work based
|
| paul@0 | 90 | on the Program.
|
| paul@0 | 91 |
|
| paul@0 | 92 | To "propagate" a work means to do anything with it that, without
|
| paul@0 | 93 | permission, would make you directly or secondarily liable for
|
| paul@0 | 94 | infringement under applicable copyright law, except executing it on a
|
| paul@0 | 95 | computer or modifying a private copy. Propagation includes copying,
|
| paul@0 | 96 | distribution (with or without modification), making available to the
|
| paul@0 | 97 | public, and in some countries other activities as well.
|
| paul@0 | 98 |
|
| paul@0 | 99 | To "convey" a work means any kind of propagation that enables other
|
| paul@0 | 100 | parties to make or receive copies. Mere interaction with a user through
|
| paul@0 | 101 | a computer network, with no transfer of a copy, is not conveying.
|
| paul@0 | 102 |
|
| paul@0 | 103 | An interactive user interface displays "Appropriate Legal Notices"
|
| paul@0 | 104 | to the extent that it includes a convenient and prominently visible
|
| paul@0 | 105 | feature that (1) displays an appropriate copyright notice, and (2)
|
| paul@0 | 106 | tells the user that there is no warranty for the work (except to the
|
| paul@0 | 107 | extent that warranties are provided), that licensees may convey the
|
| paul@0 | 108 | work under this License, and how to view a copy of this License. If
|
| paul@0 | 109 | the interface presents a list of user commands or options, such as a
|
| paul@0 | 110 | menu, a prominent item in the list meets this criterion.
|
| paul@0 | 111 |
|
| paul@0 | 112 | 1. Source Code.
|
| paul@0 | 113 |
|
| paul@0 | 114 | The "source code" for a work means the preferred form of the work
|
| paul@0 | 115 | for making modifications to it. "Object code" means any non-source
|
| paul@0 | 116 | form of a work.
|
| paul@0 | 117 |
|
| paul@0 | 118 | A "Standard Interface" means an interface that either is an official
|
| paul@0 | 119 | standard defined by a recognized standards body, or, in the case of
|
| paul@0 | 120 | interfaces specified for a particular programming language, one that
|
| paul@0 | 121 | is widely used among developers working in that language.
|
| paul@0 | 122 |
|
| paul@0 | 123 | The "System Libraries" of an executable work include anything, other
|
| paul@0 | 124 | than the work as a whole, that (a) is included in the normal form of
|
| paul@0 | 125 | packaging a Major Component, but which is not part of that Major
|
| paul@0 | 126 | Component, and (b) serves only to enable use of the work with that
|
| paul@0 | 127 | Major Component, or to implement a Standard Interface for which an
|
| paul@0 | 128 | implementation is available to the public in source code form. A
|
| paul@0 | 129 | "Major Component", in this context, means a major essential component
|
| paul@0 | 130 | (kernel, window system, and so on) of the specific operating system
|
| paul@0 | 131 | (if any) on which the executable work runs, or a compiler used to
|
| paul@0 | 132 | produce the work, or an object code interpreter used to run it.
|
| paul@0 | 133 |
|
| paul@0 | 134 | The "Corresponding Source" for a work in object code form means all
|
| paul@0 | 135 | the source code needed to generate, install, and (for an executable
|
| paul@0 | 136 | work) run the object code and to modify the work, including scripts to
|
| paul@0 | 137 | control those activities. However, it does not include the work's
|
| paul@0 | 138 | System Libraries, or general-purpose tools or generally available free
|
| paul@0 | 139 | programs which are used unmodified in performing those activities but
|
| paul@0 | 140 | which are not part of the work. For example, Corresponding Source
|
| paul@0 | 141 | includes interface definition files associated with source files for
|
| paul@0 | 142 | the work, and the source code for shared libraries and dynamically
|
| paul@0 | 143 | linked subprograms that the work is specifically designed to require,
|
| paul@0 | 144 | such as by intimate data communication or control flow between those
|
| paul@0 | 145 | subprograms and other parts of the work.
|
| paul@0 | 146 |
|
| paul@0 | 147 | The Corresponding Source need not include anything that users
|
| paul@0 | 148 | can regenerate automatically from other parts of the Corresponding
|
| paul@0 | 149 | Source.
|
| paul@0 | 150 |
|
| paul@0 | 151 | The Corresponding Source for a work in source code form is that
|
| paul@0 | 152 | same work.
|
| paul@0 | 153 |
|
| paul@0 | 154 | 2. Basic Permissions.
|
| paul@0 | 155 |
|
| paul@0 | 156 | All rights granted under this License are granted for the term of
|
| paul@0 | 157 | copyright on the Program, and are irrevocable provided the stated
|
| paul@0 | 158 | conditions are met. This License explicitly affirms your unlimited
|
| paul@0 | 159 | permission to run the unmodified Program. The output from running a
|
| paul@0 | 160 | covered work is covered by this License only if the output, given its
|
| paul@0 | 161 | content, constitutes a covered work. This License acknowledges your
|
| paul@0 | 162 | rights of fair use or other equivalent, as provided by copyright law.
|
| paul@0 | 163 |
|
| paul@0 | 164 | You may make, run and propagate covered works that you do not
|
| paul@0 | 165 | convey, without conditions so long as your license otherwise remains
|
| paul@0 | 166 | in force. You may convey covered works to others for the sole purpose
|
| paul@0 | 167 | of having them make modifications exclusively for you, or provide you
|
| paul@0 | 168 | with facilities for running those works, provided that you comply with
|
| paul@0 | 169 | the terms of this License in conveying all material for which you do
|
| paul@0 | 170 | not control copyright. Those thus making or running the covered works
|
| paul@0 | 171 | for you must do so exclusively on your behalf, under your direction
|
| paul@0 | 172 | and control, on terms that prohibit them from making any copies of
|
| paul@0 | 173 | your copyrighted material outside their relationship with you.
|
| paul@0 | 174 |
|
| paul@0 | 175 | Conveying under any other circumstances is permitted solely under
|
| paul@0 | 176 | the conditions stated below. Sublicensing is not allowed; section 10
|
| paul@0 | 177 | makes it unnecessary.
|
| paul@0 | 178 |
|
| paul@0 | 179 | 3. Protecting Users' Legal Rights From Anti-Circumvention Law.
|
| paul@0 | 180 |
|
| paul@0 | 181 | No covered work shall be deemed part of an effective technological
|
| paul@0 | 182 | measure under any applicable law fulfilling obligations under article
|
| paul@0 | 183 | 11 of the WIPO copyright treaty adopted on 20 December 1996, or
|
| paul@0 | 184 | similar laws prohibiting or restricting circumvention of such
|
| paul@0 | 185 | measures.
|
| paul@0 | 186 |
|
| paul@0 | 187 | When you convey a covered work, you waive any legal power to forbid
|
| paul@0 | 188 | circumvention of technological measures to the extent such circumvention
|
| paul@0 | 189 | is effected by exercising rights under this License with respect to
|
| paul@0 | 190 | the covered work, and you disclaim any intention to limit operation or
|
| paul@0 | 191 | modification of the work as a means of enforcing, against the work's
|
| paul@0 | 192 | users, your or third parties' legal rights to forbid circumvention of
|
| paul@0 | 193 | technological measures.
|
| paul@0 | 194 |
|
| paul@0 | 195 | 4. Conveying Verbatim Copies.
|
| paul@0 | 196 |
|
| paul@0 | 197 | You may convey verbatim copies of the Program's source code as you
|
| paul@0 | 198 | receive it, in any medium, provided that you conspicuously and
|
| paul@0 | 199 | appropriately publish on each copy an appropriate copyright notice;
|
| paul@0 | 200 | keep intact all notices stating that this License and any
|
| paul@0 | 201 | non-permissive terms added in accord with section 7 apply to the code;
|
| paul@0 | 202 | keep intact all notices of the absence of any warranty; and give all
|
| paul@0 | 203 | recipients a copy of this License along with the Program.
|
| paul@0 | 204 |
|
| paul@0 | 205 | You may charge any price or no price for each copy that you convey,
|
| paul@0 | 206 | and you may offer support or warranty protection for a fee.
|
| paul@0 | 207 |
|
| paul@0 | 208 | 5. Conveying Modified Source Versions.
|
| paul@0 | 209 |
|
| paul@0 | 210 | You may convey a work based on the Program, or the modifications to
|
| paul@0 | 211 | produce it from the Program, in the form of source code under the
|
| paul@0 | 212 | terms of section 4, provided that you also meet all of these conditions:
|
| paul@0 | 213 |
|
| paul@0 | 214 | a) The work must carry prominent notices stating that you modified
|
| paul@0 | 215 | it, and giving a relevant date.
|
| paul@0 | 216 |
|
| paul@0 | 217 | b) The work must carry prominent notices stating that it is
|
| paul@0 | 218 | released under this License and any conditions added under section
|
| paul@0 | 219 | 7. This requirement modifies the requirement in section 4 to
|
| paul@0 | 220 | "keep intact all notices".
|
| paul@0 | 221 |
|
| paul@0 | 222 | c) You must license the entire work, as a whole, under this
|
| paul@0 | 223 | License to anyone who comes into possession of a copy. This
|
| paul@0 | 224 | License will therefore apply, along with any applicable section 7
|
| paul@0 | 225 | additional terms, to the whole of the work, and all its parts,
|
| paul@0 | 226 | regardless of how they are packaged. This License gives no
|
| paul@0 | 227 | permission to license the work in any other way, but it does not
|
| paul@0 | 228 | invalidate such permission if you have separately received it.
|
| paul@0 | 229 |
|
| paul@0 | 230 | d) If the work has interactive user interfaces, each must display
|
| paul@0 | 231 | Appropriate Legal Notices; however, if the Program has interactive
|
| paul@0 | 232 | interfaces that do not display Appropriate Legal Notices, your
|
| paul@0 | 233 | work need not make them do so.
|
| paul@0 | 234 |
|
| paul@0 | 235 | A compilation of a covered work with other separate and independent
|
| paul@0 | 236 | works, which are not by their nature extensions of the covered work,
|
| paul@0 | 237 | and which are not combined with it such as to form a larger program,
|
| paul@0 | 238 | in or on a volume of a storage or distribution medium, is called an
|
| paul@0 | 239 | "aggregate" if the compilation and its resulting copyright are not
|
| paul@0 | 240 | used to limit the access or legal rights of the compilation's users
|
| paul@0 | 241 | beyond what the individual works permit. Inclusion of a covered work
|
| paul@0 | 242 | in an aggregate does not cause this License to apply to the other
|
| paul@0 | 243 | parts of the aggregate.
|
| paul@0 | 244 |
|
| paul@0 | 245 | 6. Conveying Non-Source Forms.
|
| paul@0 | 246 |
|
| paul@0 | 247 | You may convey a covered work in object code form under the terms
|
| paul@0 | 248 | of sections 4 and 5, provided that you also convey the
|
| paul@0 | 249 | machine-readable Corresponding Source under the terms of this License,
|
| paul@0 | 250 | in one of these ways:
|
| paul@0 | 251 |
|
| paul@0 | 252 | a) Convey the object code in, or embodied in, a physical product
|
| paul@0 | 253 | (including a physical distribution medium), accompanied by the
|
| paul@0 | 254 | Corresponding Source fixed on a durable physical medium
|
| paul@0 | 255 | customarily used for software interchange.
|
| paul@0 | 256 |
|
| paul@0 | 257 | b) Convey the object code in, or embodied in, a physical product
|
| paul@0 | 258 | (including a physical distribution medium), accompanied by a
|
| paul@0 | 259 | written offer, valid for at least three years and valid for as
|
| paul@0 | 260 | long as you offer spare parts or customer support for that product
|
| paul@0 | 261 | model, to give anyone who possesses the object code either (1) a
|
| paul@0 | 262 | copy of the Corresponding Source for all the software in the
|
| paul@0 | 263 | product that is covered by this License, on a durable physical
|
| paul@0 | 264 | medium customarily used for software interchange, for a price no
|
| paul@0 | 265 | more than your reasonable cost of physically performing this
|
| paul@0 | 266 | conveying of source, or (2) access to copy the
|
| paul@0 | 267 | Corresponding Source from a network server at no charge.
|
| paul@0 | 268 |
|
| paul@0 | 269 | c) Convey individual copies of the object code with a copy of the
|
| paul@0 | 270 | written offer to provide the Corresponding Source. This
|
| paul@0 | 271 | alternative is allowed only occasionally and noncommercially, and
|
| paul@0 | 272 | only if you received the object code with such an offer, in accord
|
| paul@0 | 273 | with subsection 6b.
|
| paul@0 | 274 |
|
| paul@0 | 275 | d) Convey the object code by offering access from a designated
|
| paul@0 | 276 | place (gratis or for a charge), and offer equivalent access to the
|
| paul@0 | 277 | Corresponding Source in the same way through the same place at no
|
| paul@0 | 278 | further charge. You need not require recipients to copy the
|
| paul@0 | 279 | Corresponding Source along with the object code. If the place to
|
| paul@0 | 280 | copy the object code is a network server, the Corresponding Source
|
| paul@0 | 281 | may be on a different server (operated by you or a third party)
|
| paul@0 | 282 | that supports equivalent copying facilities, provided you maintain
|
| paul@0 | 283 | clear directions next to the object code saying where to find the
|
| paul@0 | 284 | Corresponding Source. Regardless of what server hosts the
|
| paul@0 | 285 | Corresponding Source, you remain obligated to ensure that it is
|
| paul@0 | 286 | available for as long as needed to satisfy these requirements.
|
| paul@0 | 287 |
|
| paul@0 | 288 | e) Convey the object code using peer-to-peer transmission, provided
|
| paul@0 | 289 | you inform other peers where the object code and Corresponding
|
| paul@0 | 290 | Source of the work are being offered to the general public at no
|
| paul@0 | 291 | charge under subsection 6d.
|
| paul@0 | 292 |
|
| paul@0 | 293 | A separable portion of the object code, whose source code is excluded
|
| paul@0 | 294 | from the Corresponding Source as a System Library, need not be
|
| paul@0 | 295 | included in conveying the object code work.
|
| paul@0 | 296 |
|
| paul@0 | 297 | A "User Product" is either (1) a "consumer product", which means any
|
| paul@0 | 298 | tangible personal property which is normally used for personal, family,
|
| paul@0 | 299 | or household purposes, or (2) anything designed or sold for incorporation
|
| paul@0 | 300 | into a dwelling. In determining whether a product is a consumer product,
|
| paul@0 | 301 | doubtful cases shall be resolved in favor of coverage. For a particular
|
| paul@0 | 302 | product received by a particular user, "normally used" refers to a
|
| paul@0 | 303 | typical or common use of that class of product, regardless of the status
|
| paul@0 | 304 | of the particular user or of the way in which the particular user
|
| paul@0 | 305 | actually uses, or expects or is expected to use, the product. A product
|
| paul@0 | 306 | is a consumer product regardless of whether the product has substantial
|
| paul@0 | 307 | commercial, industrial or non-consumer uses, unless such uses represent
|
| paul@0 | 308 | the only significant mode of use of the product.
|
| paul@0 | 309 |
|
| paul@0 | 310 | "Installation Information" for a User Product means any methods,
|
| paul@0 | 311 | procedures, authorization keys, or other information required to install
|
| paul@0 | 312 | and execute modified versions of a covered work in that User Product from
|
| paul@0 | 313 | a modified version of its Corresponding Source. The information must
|
| paul@0 | 314 | suffice to ensure that the continued functioning of the modified object
|
| paul@0 | 315 | code is in no case prevented or interfered with solely because
|
| paul@0 | 316 | modification has been made.
|
| paul@0 | 317 |
|
| paul@0 | 318 | If you convey an object code work under this section in, or with, or
|
| paul@0 | 319 | specifically for use in, a User Product, and the conveying occurs as
|
| paul@0 | 320 | part of a transaction in which the right of possession and use of the
|
| paul@0 | 321 | User Product is transferred to the recipient in perpetuity or for a
|
| paul@0 | 322 | fixed term (regardless of how the transaction is characterized), the
|
| paul@0 | 323 | Corresponding Source conveyed under this section must be accompanied
|
| paul@0 | 324 | by the Installation Information. But this requirement does not apply
|
| paul@0 | 325 | if neither you nor any third party retains the ability to install
|
| paul@0 | 326 | modified object code on the User Product (for example, the work has
|
| paul@0 | 327 | been installed in ROM).
|
| paul@0 | 328 |
|
| paul@0 | 329 | The requirement to provide Installation Information does not include a
|
| paul@0 | 330 | requirement to continue to provide support service, warranty, or updates
|
| paul@0 | 331 | for a work that has been modified or installed by the recipient, or for
|
| paul@0 | 332 | the User Product in which it has been modified or installed. Access to a
|
| paul@0 | 333 | network may be denied when the modification itself materially and
|
| paul@0 | 334 | adversely affects the operation of the network or violates the rules and
|
| paul@0 | 335 | protocols for communication across the network.
|
| paul@0 | 336 |
|
| paul@0 | 337 | Corresponding Source conveyed, and Installation Information provided,
|
| paul@0 | 338 | in accord with this section must be in a format that is publicly
|
| paul@0 | 339 | documented (and with an implementation available to the public in
|
| paul@0 | 340 | source code form), and must require no special password or key for
|
| paul@0 | 341 | unpacking, reading or copying.
|
| paul@0 | 342 |
|
| paul@0 | 343 | 7. Additional Terms.
|
| paul@0 | 344 |
|
| paul@0 | 345 | "Additional permissions" are terms that supplement the terms of this
|
| paul@0 | 346 | License by making exceptions from one or more of its conditions.
|
| paul@0 | 347 | Additional permissions that are applicable to the entire Program shall
|
| paul@0 | 348 | be treated as though they were included in this License, to the extent
|
| paul@0 | 349 | that they are valid under applicable law. If additional permissions
|
| paul@0 | 350 | apply only to part of the Program, that part may be used separately
|
| paul@0 | 351 | under those permissions, but the entire Program remains governed by
|
| paul@0 | 352 | this License without regard to the additional permissions.
|
| paul@0 | 353 |
|
| paul@0 | 354 | When you convey a copy of a covered work, you may at your option
|
| paul@0 | 355 | remove any additional permissions from that copy, or from any part of
|
| paul@0 | 356 | it. (Additional permissions may be written to require their own
|
| paul@0 | 357 | removal in certain cases when you modify the work.) You may place
|
| paul@0 | 358 | additional permissions on material, added by you to a covered work,
|
| paul@0 | 359 | for which you have or can give appropriate copyright permission.
|
| paul@0 | 360 |
|
| paul@0 | 361 | Notwithstanding any other provision of this License, for material you
|
| paul@0 | 362 | add to a covered work, you may (if authorized by the copyright holders of
|
| paul@0 | 363 | that material) supplement the terms of this License with terms:
|
| paul@0 | 364 |
|
| paul@0 | 365 | a) Disclaiming warranty or limiting liability differently from the
|
| paul@0 | 366 | terms of sections 15 and 16 of this License; or
|
| paul@0 | 367 |
|
| paul@0 | 368 | b) Requiring preservation of specified reasonable legal notices or
|
| paul@0 | 369 | author attributions in that material or in the Appropriate Legal
|
| paul@0 | 370 | Notices displayed by works containing it; or
|
| paul@0 | 371 |
|
| paul@0 | 372 | c) Prohibiting misrepresentation of the origin of that material, or
|
| paul@0 | 373 | requiring that modified versions of such material be marked in
|
| paul@0 | 374 | reasonable ways as different from the original version; or
|
| paul@0 | 375 |
|
| paul@0 | 376 | d) Limiting the use for publicity purposes of names of licensors or
|
| paul@0 | 377 | authors of the material; or
|
| paul@0 | 378 |
|
| paul@0 | 379 | e) Declining to grant rights under trademark law for use of some
|
| paul@0 | 380 | trade names, trademarks, or service marks; or
|
| paul@0 | 381 |
|
| paul@0 | 382 | f) Requiring indemnification of licensors and authors of that
|
| paul@0 | 383 | material by anyone who conveys the material (or modified versions of
|
| paul@0 | 384 | it) with contractual assumptions of liability to the recipient, for
|
| paul@0 | 385 | any liability that these contractual assumptions directly impose on
|
| paul@0 | 386 | those licensors and authors.
|
| paul@0 | 387 |
|
| paul@0 | 388 | All other non-permissive additional terms are considered "further
|
| paul@0 | 389 | restrictions" within the meaning of section 10. If the Program as you
|
| paul@0 | 390 | received it, or any part of it, contains a notice stating that it is
|
| paul@0 | 391 | governed by this License along with a term that is a further
|
| paul@0 | 392 | restriction, you may remove that term. If a license document contains
|
| paul@0 | 393 | a further restriction but permits relicensing or conveying under this
|
| paul@0 | 394 | License, you may add to a covered work material governed by the terms
|
| paul@0 | 395 | of that license document, provided that the further restriction does
|
| paul@0 | 396 | not survive such relicensing or conveying.
|
| paul@0 | 397 |
|
| paul@0 | 398 | If you add terms to a covered work in accord with this section, you
|
| paul@0 | 399 | must place, in the relevant source files, a statement of the
|
| paul@0 | 400 | additional terms that apply to those files, or a notice indicating
|
| paul@0 | 401 | where to find the applicable terms.
|
| paul@0 | 402 |
|
| paul@0 | 403 | Additional terms, permissive or non-permissive, may be stated in the
|
| paul@0 | 404 | form of a separately written license, or stated as exceptions;
|
| paul@0 | 405 | the above requirements apply either way.
|
| paul@0 | 406 |
|
| paul@0 | 407 | 8. Termination.
|
| paul@0 | 408 |
|
| paul@0 | 409 | You may not propagate or modify a covered work except as expressly
|
| paul@0 | 410 | provided under this License. Any attempt otherwise to propagate or
|
| paul@0 | 411 | modify it is void, and will automatically terminate your rights under
|
| paul@0 | 412 | this License (including any patent licenses granted under the third
|
| paul@0 | 413 | paragraph of section 11).
|
| paul@0 | 414 |
|
| paul@0 | 415 | However, if you cease all violation of this License, then your
|
| paul@0 | 416 | license from a particular copyright holder is reinstated (a)
|
| paul@0 | 417 | provisionally, unless and until the copyright holder explicitly and
|
| paul@0 | 418 | finally terminates your license, and (b) permanently, if the copyright
|
| paul@0 | 419 | holder fails to notify you of the violation by some reasonable means
|
| paul@0 | 420 | prior to 60 days after the cessation.
|
| paul@0 | 421 |
|
| paul@0 | 422 | Moreover, your license from a particular copyright holder is
|
| paul@0 | 423 | reinstated permanently if the copyright holder notifies you of the
|
| paul@0 | 424 | violation by some reasonable means, this is the first time you have
|
| paul@0 | 425 | received notice of violation of this License (for any work) from that
|
| paul@0 | 426 | copyright holder, and you cure the violation prior to 30 days after
|
| paul@0 | 427 | your receipt of the notice.
|
| paul@0 | 428 |
|
| paul@0 | 429 | Termination of your rights under this section does not terminate the
|
| paul@0 | 430 | licenses of parties who have received copies or rights from you under
|
| paul@0 | 431 | this License. If your rights have been terminated and not permanently
|
| paul@0 | 432 | reinstated, you do not qualify to receive new licenses for the same
|
| paul@0 | 433 | material under section 10.
|
| paul@0 | 434 |
|
| paul@0 | 435 | 9. Acceptance Not Required for Having Copies.
|
| paul@0 | 436 |
|
| paul@0 | 437 | You are not required to accept this License in order to receive or
|
| paul@0 | 438 | run a copy of the Program. Ancillary propagation of a covered work
|
| paul@0 | 439 | occurring solely as a consequence of using peer-to-peer transmission
|
| paul@0 | 440 | to receive a copy likewise does not require acceptance. However,
|
| paul@0 | 441 | nothing other than this License grants you permission to propagate or
|
| paul@0 | 442 | modify any covered work. These actions infringe copyright if you do
|
| paul@0 | 443 | not accept this License. Therefore, by modifying or propagating a
|
| paul@0 | 444 | covered work, you indicate your acceptance of this License to do so.
|
| paul@0 | 445 |
|
| paul@0 | 446 | 10. Automatic Licensing of Downstream Recipients.
|
| paul@0 | 447 |
|
| paul@0 | 448 | Each time you convey a covered work, the recipient automatically
|
| paul@0 | 449 | receives a license from the original licensors, to run, modify and
|
| paul@0 | 450 | propagate that work, subject to this License. You are not responsible
|
| paul@0 | 451 | for enforcing compliance by third parties with this License.
|
| paul@0 | 452 |
|
| paul@0 | 453 | An "entity transaction" is a transaction transferring control of an
|
| paul@0 | 454 | organization, or substantially all assets of one, or subdividing an
|
| paul@0 | 455 | organization, or merging organizations. If propagation of a covered
|
| paul@0 | 456 | work results from an entity transaction, each party to that
|
| paul@0 | 457 | transaction who receives a copy of the work also receives whatever
|
| paul@0 | 458 | licenses to the work the party's predecessor in interest had or could
|
| paul@0 | 459 | give under the previous paragraph, plus a right to possession of the
|
| paul@0 | 460 | Corresponding Source of the work from the predecessor in interest, if
|
| paul@0 | 461 | the predecessor has it or can get it with reasonable efforts.
|
| paul@0 | 462 |
|
| paul@0 | 463 | You may not impose any further restrictions on the exercise of the
|
| paul@0 | 464 | rights granted or affirmed under this License. For example, you may
|
| paul@0 | 465 | not impose a license fee, royalty, or other charge for exercise of
|
| paul@0 | 466 | rights granted under this License, and you may not initiate litigation
|
| paul@0 | 467 | (including a cross-claim or counterclaim in a lawsuit) alleging that
|
| paul@0 | 468 | any patent claim is infringed by making, using, selling, offering for
|
| paul@0 | 469 | sale, or importing the Program or any portion of it.
|
| paul@0 | 470 |
|
| paul@0 | 471 | 11. Patents.
|
| paul@0 | 472 |
|
| paul@0 | 473 | A "contributor" is a copyright holder who authorizes use under this
|
| paul@0 | 474 | License of the Program or a work on which the Program is based. The
|
| paul@0 | 475 | work thus licensed is called the contributor's "contributor version".
|
| paul@0 | 476 |
|
| paul@0 | 477 | A contributor's "essential patent claims" are all patent claims
|
| paul@0 | 478 | owned or controlled by the contributor, whether already acquired or
|
| paul@0 | 479 | hereafter acquired, that would be infringed by some manner, permitted
|
| paul@0 | 480 | by this License, of making, using, or selling its contributor version,
|
| paul@0 | 481 | but do not include claims that would be infringed only as a
|
| paul@0 | 482 | consequence of further modification of the contributor version. For
|
| paul@0 | 483 | purposes of this definition, "control" includes the right to grant
|
| paul@0 | 484 | patent sublicenses in a manner consistent with the requirements of
|
| paul@0 | 485 | this License.
|
| paul@0 | 486 |
|
| paul@0 | 487 | Each contributor grants you a non-exclusive, worldwide, royalty-free
|
| paul@0 | 488 | patent license under the contributor's essential patent claims, to
|
| paul@0 | 489 | make, use, sell, offer for sale, import and otherwise run, modify and
|
| paul@0 | 490 | propagate the contents of its contributor version.
|
| paul@0 | 491 |
|
| paul@0 | 492 | In the following three paragraphs, a "patent license" is any express
|
| paul@0 | 493 | agreement or commitment, however denominated, not to enforce a patent
|
| paul@0 | 494 | (such as an express permission to practice a patent or covenant not to
|
| paul@0 | 495 | sue for patent infringement). To "grant" such a patent license to a
|
| paul@0 | 496 | party means to make such an agreement or commitment not to enforce a
|
| paul@0 | 497 | patent against the party.
|
| paul@0 | 498 |
|
| paul@0 | 499 | If you convey a covered work, knowingly relying on a patent license,
|
| paul@0 | 500 | and the Corresponding Source of the work is not available for anyone
|
| paul@0 | 501 | to copy, free of charge and under the terms of this License, through a
|
| paul@0 | 502 | publicly available network server or other readily accessible means,
|
| paul@0 | 503 | then you must either (1) cause the Corresponding Source to be so
|
| paul@0 | 504 | available, or (2) arrange to deprive yourself of the benefit of the
|
| paul@0 | 505 | patent license for this particular work, or (3) arrange, in a manner
|
| paul@0 | 506 | consistent with the requirements of this License, to extend the patent
|
| paul@0 | 507 | license to downstream recipients. "Knowingly relying" means you have
|
| paul@0 | 508 | actual knowledge that, but for the patent license, your conveying the
|
| paul@0 | 509 | covered work in a country, or your recipient's use of the covered work
|
| paul@0 | 510 | in a country, would infringe one or more identifiable patents in that
|
| paul@0 | 511 | country that you have reason to believe are valid.
|
| paul@0 | 512 |
|
| paul@0 | 513 | If, pursuant to or in connection with a single transaction or
|
| paul@0 | 514 | arrangement, you convey, or propagate by procuring conveyance of, a
|
| paul@0 | 515 | covered work, and grant a patent license to some of the parties
|
| paul@0 | 516 | receiving the covered work authorizing them to use, propagate, modify
|
| paul@0 | 517 | or convey a specific copy of the covered work, then the patent license
|
| paul@0 | 518 | you grant is automatically extended to all recipients of the covered
|
| paul@0 | 519 | work and works based on it.
|
| paul@0 | 520 |
|
| paul@0 | 521 | A patent license is "discriminatory" if it does not include within
|
| paul@0 | 522 | the scope of its coverage, prohibits the exercise of, or is
|
| paul@0 | 523 | conditioned on the non-exercise of one or more of the rights that are
|
| paul@0 | 524 | specifically granted under this License. You may not convey a covered
|
| paul@0 | 525 | work if you are a party to an arrangement with a third party that is
|
| paul@0 | 526 | in the business of distributing software, under which you make payment
|
| paul@0 | 527 | to the third party based on the extent of your activity of conveying
|
| paul@0 | 528 | the work, and under which the third party grants, to any of the
|
| paul@0 | 529 | parties who would receive the covered work from you, a discriminatory
|
| paul@0 | 530 | patent license (a) in connection with copies of the covered work
|
| paul@0 | 531 | conveyed by you (or copies made from those copies), or (b) primarily
|
| paul@0 | 532 | for and in connection with specific products or compilations that
|
| paul@0 | 533 | contain the covered work, unless you entered into that arrangement,
|
| paul@0 | 534 | or that patent license was granted, prior to 28 March 2007.
|
| paul@0 | 535 |
|
| paul@0 | 536 | Nothing in this License shall be construed as excluding or limiting
|
| paul@0 | 537 | any implied license or other defenses to infringement that may
|
| paul@0 | 538 | otherwise be available to you under applicable patent law.
|
| paul@0 | 539 |
|
| paul@0 | 540 | 12. No Surrender of Others' Freedom.
|
| paul@0 | 541 |
|
| paul@0 | 542 | If conditions are imposed on you (whether by court order, agreement or
|
| paul@0 | 543 | otherwise) that contradict the conditions of this License, they do not
|
| paul@0 | 544 | excuse you from the conditions of this License. If you cannot convey a
|
| paul@0 | 545 | covered work so as to satisfy simultaneously your obligations under this
|
| paul@0 | 546 | License and any other pertinent obligations, then as a consequence you may
|
| paul@0 | 547 | not convey it at all. For example, if you agree to terms that obligate you
|
| paul@0 | 548 | to collect a royalty for further conveying from those to whom you convey
|
| paul@0 | 549 | the Program, the only way you could satisfy both those terms and this
|
| paul@0 | 550 | License would be to refrain entirely from conveying the Program.
|
| paul@0 | 551 |
|
| paul@0 | 552 | 13. Use with the GNU Affero General Public License.
|
| paul@0 | 553 |
|
| paul@0 | 554 | Notwithstanding any other provision of this License, you have
|
| paul@0 | 555 | permission to link or combine any covered work with a work licensed
|
| paul@0 | 556 | under version 3 of the GNU Affero General Public License into a single
|
| paul@0 | 557 | combined work, and to convey the resulting work. The terms of this
|
| paul@0 | 558 | License will continue to apply to the part which is the covered work,
|
| paul@0 | 559 | but the special requirements of the GNU Affero General Public License,
|
| paul@0 | 560 | section 13, concerning interaction through a network will apply to the
|
| paul@0 | 561 | combination as such.
|
| paul@0 | 562 |
|
| paul@0 | 563 | 14. Revised Versions of this License.
|
| paul@0 | 564 |
|
| paul@0 | 565 | The Free Software Foundation may publish revised and/or new versions of
|
| paul@0 | 566 | the GNU General Public License from time to time. Such new versions will
|
| paul@0 | 567 | be similar in spirit to the present version, but may differ in detail to
|
| paul@0 | 568 | address new problems or concerns.
|
| paul@0 | 569 |
|
| paul@0 | 570 | Each version is given a distinguishing version number. If the
|
| paul@0 | 571 | Program specifies that a certain numbered version of the GNU General
|
| paul@0 | 572 | Public License "or any later version" applies to it, you have the
|
| paul@0 | 573 | option of following the terms and conditions either of that numbered
|
| paul@0 | 574 | version or of any later version published by the Free Software
|
| paul@0 | 575 | Foundation. If the Program does not specify a version number of the
|
| paul@0 | 576 | GNU General Public License, you may choose any version ever published
|
| paul@0 | 577 | by the Free Software Foundation.
|
| paul@0 | 578 |
|
| paul@0 | 579 | If the Program specifies that a proxy can decide which future
|
| paul@0 | 580 | versions of the GNU General Public License can be used, that proxy's
|
| paul@0 | 581 | public statement of acceptance of a version permanently authorizes you
|
| paul@0 | 582 | to choose that version for the Program.
|
| paul@0 | 583 |
|
| paul@0 | 584 | Later license versions may give you additional or different
|
| paul@0 | 585 | permissions. However, no additional obligations are imposed on any
|
| paul@0 | 586 | author or copyright holder as a result of your choosing to follow a
|
| paul@0 | 587 | later version.
|
| paul@0 | 588 |
|
| paul@0 | 589 | 15. Disclaimer of Warranty.
|
| paul@0 | 590 |
|
| paul@0 | 591 | THERE IS NO WARRANTY FOR THE PROGRAM, TO THE EXTENT PERMITTED BY
|
| paul@0 | 592 | APPLICABLE LAW. EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT
|
| paul@0 | 593 | HOLDERS AND/OR OTHER PARTIES PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY
|
| paul@0 | 594 | OF ANY KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO,
|
| paul@0 | 595 | THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR
|
| paul@0 | 596 | PURPOSE. THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE PROGRAM
|
| paul@0 | 597 | IS WITH YOU. SHOULD THE PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF
|
| paul@0 | 598 | ALL NECESSARY SERVICING, REPAIR OR CORRECTION.
|
| paul@0 | 599 |
|
| paul@0 | 600 | 16. Limitation of Liability.
|
| paul@0 | 601 |
|
| paul@0 | 602 | IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
|
| paul@0 | 603 | WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MODIFIES AND/OR CONVEYS
|
| paul@0 | 604 | THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, INCLUDING ANY
|
| paul@0 | 605 | GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING OUT OF THE
|
| paul@0 | 606 | USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED TO LOSS OF
|
| paul@0 | 607 | DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD
|
| paul@0 | 608 | PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER PROGRAMS),
|
| paul@0 | 609 | EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF
|
| paul@0 | 610 | SUCH DAMAGES.
|
| paul@0 | 611 |
|
| paul@0 | 612 | 17. Interpretation of Sections 15 and 16.
|
| paul@0 | 613 |
|
| paul@0 | 614 | If the disclaimer of warranty and limitation of liability provided
|
| paul@0 | 615 | above cannot be given local legal effect according to their terms,
|
| paul@0 | 616 | reviewing courts shall apply local law that most closely approximates
|
| paul@0 | 617 | an absolute waiver of all civil liability in connection with the
|
| paul@0 | 618 | Program, unless a warranty or assumption of liability accompanies a
|
| paul@0 | 619 | copy of the Program in return for a fee.
|
| paul@0 | 620 |
|
| paul@0 | 621 | END OF TERMS AND CONDITIONS
|
| paul@0 | 622 |
|
| paul@0 | 623 | How to Apply These Terms to Your New Programs
|
| paul@0 | 624 |
|
| paul@0 | 625 | If you develop a new program, and you want it to be of the greatest
|
| paul@0 | 626 | possible use to the public, the best way to achieve this is to make it
|
| paul@0 | 627 | free software which everyone can redistribute and change under these terms.
|
| paul@0 | 628 |
|
| paul@0 | 629 | To do so, attach the following notices to the program. It is safest
|
| paul@0 | 630 | to attach them to the start of each source file to most effectively
|
| paul@0 | 631 | state the exclusion of warranty; and each file should have at least
|
| paul@0 | 632 | the "copyright" line and a pointer to where the full notice is found.
|
| paul@0 | 633 |
|
| paul@0 | 634 | <one line to give the program's name and a brief idea of what it does.>
|

|

|
| paul@0 | 650 | Also add information on how to contact you by electronic and paper mail.
|
| paul@0 | 651 |
|
| paul@0 | 652 | If the program does terminal interaction, make it output a short
|
| paul@0 | 653 | notice like this when it starts in an interactive mode:
|
| paul@0 | 654 |
|
| paul@0 | 655 | <program> Copyright (C) <year> <name of author>

|
| paul@0 | 660 | The hypothetical commands `show w' and `show c' should show the appropriate
