2.4 - GNU LESSER GENERAL PUBLIC LICENSE
2.5 - Version 2.1, February 1999
2.6 -
2.7 - Copyright (C) 1991, 1999 Free Software Foundation, Inc.
2.8 - 51 Franklin Street, Fifth Floor, Boston, MA 02110-1301, USA
2.9 - Everyone is permitted to copy and distribute verbatim copies
2.10 - of this license document, but changing it is not allowed.
2.11 -
2.12 -[This is the first released version of the Lesser GPL. It also counts
2.13 - as the successor of the GNU Library Public License, version 2, hence
2.14 - the version number 2.1.]
2.15 -
2.16 - Preamble
2.17 -
2.18 - The licenses for most software are designed to take away your
2.19 -freedom to share and change it. By contrast, the GNU General Public
2.20 -Licenses are intended to guarantee your freedom to share and change
2.21 -free software--to make sure the software is free for all its users.
2.22 -
2.23 - This license, the Lesser General Public License, applies to some
2.24 -specially designated software packages--typically libraries--of the
2.25 -Free Software Foundation and other authors who decide to use it. You
2.26 -can use it too, but we suggest you first think carefully about whether
2.27 -this license or the ordinary General Public License is the better
2.28 -strategy to use in any particular case, based on the explanations below.
2.29 -
2.30 - When we speak of free software, we are referring to freedom of use,
2.31 -not price. Our General Public Licenses are designed to make sure that
2.32 -you have the freedom to distribute copies of free software (and charge
2.33 -for this service if you wish); that you receive source code or can get
2.34 -it if you want it; that you can change the software and use pieces of
2.35 -it in new free programs; and that you are informed that you can do
2.36 -these things.
2.37 -
2.38 - To protect your rights, we need to make restrictions that forbid
2.39 -distributors to deny you these rights or to ask you to surrender these
2.40 -rights. These restrictions translate to certain responsibilities for
2.41 -you if you distribute copies of the library or if you modify it.
2.42 -
2.43 - For example, if you distribute copies of the library, whether gratis
2.44 -or for a fee, you must give the recipients all the rights that we gave
2.45 -you. You must make sure that they, too, receive or can get the source
2.46 -code. If you link other code with the library, you must provide
2.47 -complete object files to the recipients, so that they can relink them
2.48 -with the library after making changes to the library and recompiling
2.49 -it. And you must show them these terms so they know their rights.
2.50 -
2.51 - We protect your rights with a two-step method: (1) we copyright the
2.52 -library, and (2) we offer you this license, which gives you legal
2.53 -permission to copy, distribute and/or modify the library.
2.54 -
2.55 - To protect each distributor, we want to make it very clear that
2.56 -there is no warranty for the free library. Also, if the library is
2.57 -modified by someone else and passed on, the recipients should know
2.58 -that what they have is not the original version, so that the original
2.59 -author's reputation will not be affected by problems that might be
2.60 -introduced by others.
2.61 -
2.62 - Finally, software patents pose a constant threat to the existence of
2.63 -any free program. We wish to make sure that a company cannot
2.64 -effectively restrict the users of a free program by obtaining a
2.65 -restrictive license from a patent holder. Therefore, we insist that
2.66 -any patent license obtained for a version of the library must be
2.67 -consistent with the full freedom of use specified in this license.
2.68 -
2.69 - Most GNU software, including some libraries, is covered by the
2.70 -ordinary GNU General Public License. This license, the GNU Lesser
2.71 -General Public License, applies to certain designated libraries, and
2.72 -is quite different from the ordinary General Public License. We use
2.73 -this license for certain libraries in order to permit linking those
2.74 -libraries into non-free programs.
2.75 -
2.76 - When a program is linked with a library, whether statically or using
2.77 -a shared library, the combination of the two is legally speaking a
2.78 -combined work, a derivative of the original library. The ordinary
2.79 -General Public License therefore permits such linking only if the
2.80 -entire combination fits its criteria of freedom. The Lesser General
2.81 -Public License permits more lax criteria for linking other code with
2.82 -the library.
2.83 -
2.84 - We call this license the "Lesser" General Public License because it
2.85 -does Less to protect the user's freedom than the ordinary General
2.86 -Public License. It also provides other free software developers Less
2.87 -of an advantage over competing non-free programs. These disadvantages
2.88 -are the reason we use the ordinary General Public License for many
2.89 -libraries. However, the Lesser license provides advantages in certain
2.90 -special circumstances.
2.91 -
2.92 - For example, on rare occasions, there may be a special need to
2.93 -encourage the widest possible use of a certain library, so that it becomes
2.94 -a de-facto standard. To achieve this, non-free programs must be
2.95 -allowed to use the library. A more frequent case is that a free
2.96 -library does the same job as widely used non-free libraries. In this
2.97 -case, there is little to gain by limiting the free library to free
2.98 -software only, so we use the Lesser General Public License.
2.99 -
2.100 - In other cases, permission to use a particular library in non-free
2.101 -programs enables a greater number of people to use a large body of
2.102 -free software. For example, permission to use the GNU C Library in
2.103 -non-free programs enables many more people to use the whole GNU
2.104 -operating system, as well as its variant, the GNU/Linux operating
2.105 -system.
2.106 -
2.107 - Although the Lesser General Public License is Less protective of the
2.108 -users' freedom, it does ensure that the user of a program that is
2.109 -linked with the Library has the freedom and the wherewithal to run
2.110 -that program using a modified version of the Library.
2.111 -
2.112 - The precise terms and conditions for copying, distribution and
2.113 -modification follow. Pay close attention to the difference between a
2.114 -"work based on the library" and a "work that uses the library". The
2.115 -former contains code derived from the library, whereas the latter must
2.116 -be combined with the library in order to run.
2.117 -
2.118 - GNU LESSER GENERAL PUBLIC LICENSE
2.119 - TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
2.120 -
2.121 - 0. This License Agreement applies to any software library or other
2.122 -program which contains a notice placed by the copyright holder or
2.123 -other authorized party saying it may be distributed under the terms of
2.124 -this Lesser General Public License (also called "this License").
2.125 -Each licensee is addressed as "you".
2.126 -
2.127 - A "library" means a collection of software functions and/or data
2.128 -prepared so as to be conveniently linked with application programs
2.129 -(which use some of those functions and data) to form executables.
2.130 -
2.131 - The "Library", below, refers to any such software library or work
2.132 -which has been distributed under these terms. A "work based on the
2.133 -Library" means either the Library or any derivative work under
2.134 -copyright law: that is to say, a work containing the Library or a
2.135 -portion of it, either verbatim or with modifications and/or translated
2.136 -straightforwardly into another language. (Hereinafter, translation is
2.137 -included without limitation in the term "modification".)
2.138 -
2.139 - "Source code" for a work means the preferred form of the work for
2.140 -making modifications to it. For a library, complete source code means
2.141 -all the source code for all modules it contains, plus any associated
2.142 -interface definition files, plus the scripts used to control compilation
2.143 -and installation of the library.
2.144 -
2.145 - Activities other than copying, distribution and modification are not
2.146 -covered by this License; they are outside its scope. The act of
2.147 -running a program using the Library is not restricted, and output from
2.148 -such a program is covered only if its contents constitute a work based
2.149 -on the Library (independent of the use of the Library in a tool for
2.150 -writing it). Whether that is true depends on what the Library does
2.151 -and what the program that uses the Library does.
2.152 -
2.153 - 1. You may copy and distribute verbatim copies of the Library's
2.154 -complete source code as you receive it, in any medium, provided that
2.155 -you conspicuously and appropriately publish on each copy an
2.156 -appropriate copyright notice and disclaimer of warranty; keep intact
2.157 -all the notices that refer to this License and to the absence of any
2.158 -warranty; and distribute a copy of this License along with the
2.159 -Library.
2.160 -
2.161 - You may charge a fee for the physical act of transferring a copy,
2.162 -and you may at your option offer warranty protection in exchange for a
2.163 -fee.
2.164 -
2.165 - 2. You may modify your copy or copies of the Library or any portion
2.166 -of it, thus forming a work based on the Library, and copy and
2.167 -distribute such modifications or work under the terms of Section 1
2.168 -above, provided that you also meet all of these conditions:
2.169 -
2.170 - a) The modified work must itself be a software library.
2.171 -
2.172 - b) You must cause the files modified to carry prominent notices
2.173 - stating that you changed the files and the date of any change.
2.174 -
2.175 - c) You must cause the whole of the work to be licensed at no
2.176 - charge to all third parties under the terms of this License.
2.177 -
2.178 - d) If a facility in the modified Library refers to a function or a
2.179 - table of data to be supplied by an application program that uses
2.180 - the facility, other than as an argument passed when the facility
2.181 - is invoked, then you must make a good faith effort to ensure that,
2.182 - in the event an application does not supply such function or
2.183 - table, the facility still operates, and performs whatever part of
2.184 - its purpose remains meaningful.
2.185 -
2.186 - (For example, a function in a library to compute square roots has
2.187 - a purpose that is entirely well-defined independent of the
2.188 - application. Therefore, Subsection 2d requires that any
2.189 - application-supplied function or table used by this function must
2.190 - be optional: if the application does not supply it, the square
2.191 - root function must still compute square roots.)
2.192 -
2.193 -These requirements apply to the modified work as a whole. If
2.194 -identifiable sections of that work are not derived from the Library,
2.195 -and can be reasonably considered independent and separate works in
2.196 -themselves, then this License, and its terms, do not apply to those
2.197 -sections when you distribute them as separate works. But when you
2.198 -distribute the same sections as part of a whole which is a work based
2.199 -on the Library, the distribution of the whole must be on the terms of
2.200 -this License, whose permissions for other licensees extend to the
2.201 -entire whole, and thus to each and every part regardless of who wrote
2.202 -it.
2.203 -
2.204 -Thus, it is not the intent of this section to claim rights or contest
2.205 -your rights to work written entirely by you; rather, the intent is to
2.206 -exercise the right to control the distribution of derivative or
2.207 -collective works based on the Library.
2.208 -
2.209 -In addition, mere aggregation of another work not based on the Library
2.210 -with the Library (or with a work based on the Library) on a volume of
2.211 -a storage or distribution medium does not bring the other work under
2.212 -the scope of this License.
2.213 -
2.214 - 3. You may opt to apply the terms of the ordinary GNU General Public
2.215 -License instead of this License to a given copy of the Library. To do
2.216 -this, you must alter all the notices that refer to this License, so
2.217 -that they refer to the ordinary GNU General Public License, version 2,
2.218 -instead of to this License. (If a newer version than version 2 of the
2.219 -ordinary GNU General Public License has appeared, then you can specify
2.220 -that version instead if you wish.) Do not make any other change in
2.221 -these notices.
2.222 -
2.223 - Once this change is made in a given copy, it is irreversible for
2.224 -that copy, so the ordinary GNU General Public License applies to all
2.225 -subsequent copies and derivative works made from that copy.
2.226 -
2.227 - This option is useful when you wish to copy part of the code of
2.228 -the Library into a program that is not a library.
2.229 -
2.230 - 4. You may copy and distribute the Library (or a portion or
2.231 -derivative of it, under Section 2) in object code or executable form
2.232 -under the terms of Sections 1 and 2 above provided that you accompany
2.233 -it with the complete corresponding machine-readable source code, which
2.234 -must be distributed under the terms of Sections 1 and 2 above on a
2.235 -medium customarily used for software interchange.
2.236 -
2.237 - If distribution of object code is made by offering access to copy
2.238 -from a designated place, then offering equivalent access to copy the
2.239 -source code from the same place satisfies the requirement to
2.240 -distribute the source code, even though third parties are not
2.241 -compelled to copy the source along with the object code.
2.242 -
2.243 - 5. A program that contains no derivative of any portion of the
2.244 -Library, but is designed to work with the Library by being compiled or
2.245 -linked with it, is called a "work that uses the Library". Such a
2.246 -work, in isolation, is not a derivative work of the Library, and
2.247 -therefore falls outside the scope of this License.
2.248 -
2.249 - However, linking a "work that uses the Library" with the Library
2.250 -creates an executable that is a derivative of the Library (because it
2.251 -contains portions of the Library), rather than a "work that uses the
2.252 -library". The executable is therefore covered by this License.
2.253 -Section 6 states terms for distribution of such executables.
2.254 -
2.255 - When a "work that uses the Library" uses material from a header file
2.256 -that is part of the Library, the object code for the work may be a
2.257 -derivative work of the Library even though the source code is not.
2.258 -Whether this is true is especially significant if the work can be
2.259 -linked without the Library, or if the work is itself a library. The
2.260 -threshold for this to be true is not precisely defined by law.
2.261 -
2.262 - If such an object file uses only numerical parameters, data
2.263 -structure layouts and accessors, and small macros and small inline
2.264 -functions (ten lines or less in length), then the use of the object
2.265 -file is unrestricted, regardless of whether it is legally a derivative
2.266 -work. (Executables containing this object code plus portions of the
2.267 -Library will still fall under Section 6.)
2.268 -
2.269 - Otherwise, if the work is a derivative of the Library, you may
2.270 -distribute the object code for the work under the terms of Section 6.
2.271 -Any executables containing that work also fall under Section 6,
2.272 -whether or not they are linked directly with the Library itself.
2.273 -
2.274 - 6. As an exception to the Sections above, you may also combine or
2.275 -link a "work that uses the Library" with the Library to produce a
2.276 -work containing portions of the Library, and distribute that work
2.277 -under terms of your choice, provided that the terms permit
2.278 -modification of the work for the customer's own use and reverse
2.279 -engineering for debugging such modifications.
2.280 -
2.281 - You must give prominent notice with each copy of the work that the
2.282 -Library is used in it and that the Library and its use are covered by
2.283 -this License. You must supply a copy of this License. If the work
2.284 -during execution displays copyright notices, you must include the
2.285 -copyright notice for the Library among them, as well as a reference
2.286 -directing the user to the copy of this License. Also, you must do one
2.287 -of these things:
2.288 -
2.289 - a) Accompany the work with the complete corresponding
2.290 - machine-readable source code for the Library including whatever
2.291 - changes were used in the work (which must be distributed under
2.292 - Sections 1 and 2 above); and, if the work is an executable linked
2.293 - with the Library, with the complete machine-readable "work that
2.294 - uses the Library", as object code and/or source code, so that the
2.295 - user can modify the Library and then relink to produce a modified
2.296 - executable containing the modified Library. (It is understood
2.297 - that the user who changes the contents of definitions files in the
2.298 - Library will not necessarily be able to recompile the application
2.299 - to use the modified definitions.)
2.300 -
2.301 - b) Use a suitable shared library mechanism for linking with the
2.302 - Library. A suitable mechanism is one that (1) uses at run time a
2.303 - copy of the library already present on the user's computer system,
2.304 - rather than copying library functions into the executable, and (2)
2.305 - will operate properly with a modified version of the library, if
2.306 - the user installs one, as long as the modified version is
2.307 - interface-compatible with the version that the work was made with.
2.308 -
2.309 - c) Accompany the work with a written offer, valid for at
2.310 - least three years, to give the same user the materials
2.311 - specified in Subsection 6a, above, for a charge no more
2.312 - than the cost of performing this distribution.
2.313 -
2.314 - d) If distribution of the work is made by offering access to copy
2.315 - from a designated place, offer equivalent access to copy the above
2.316 - specified materials from the same place.
2.317 -
2.318 - e) Verify that the user has already received a copy of these
2.319 - materials or that you have already sent this user a copy.
2.320 -
2.321 - For an executable, the required form of the "work that uses the
2.322 -Library" must include any data and utility programs needed for
2.323 -reproducing the executable from it. However, as a special exception,
2.324 -the materials to be distributed need not include anything that is
2.325 -normally distributed (in either source or binary form) with the major
2.326 -components (compiler, kernel, and so on) of the operating system on
2.327 -which the executable runs, unless that component itself accompanies
2.328 -the executable.
2.329 -
2.330 - It may happen that this requirement contradicts the license
2.331 -restrictions of other proprietary libraries that do not normally
2.332 -accompany the operating system. Such a contradiction means you cannot
2.333 -use both them and the Library together in an executable that you
2.334 -distribute.
2.335 -
2.336 - 7. You may place library facilities that are a work based on the
2.337 -Library side-by-side in a single library together with other library
2.338 -facilities not covered by this License, and distribute such a combined
2.339 -library, provided that the separate distribution of the work based on
2.340 -the Library and of the other library facilities is otherwise
2.341 -permitted, and provided that you do these two things:
2.342 -
2.343 - a) Accompany the combined library with a copy of the same work
2.344 - based on the Library, uncombined with any other library
2.345 - facilities. This must be distributed under the terms of the
2.346 - Sections above.
2.347 -
2.348 - b) Give prominent notice with the combined library of the fact
2.349 - that part of it is a work based on the Library, and explaining
2.350 - where to find the accompanying uncombined form of the same work.
2.351 -
2.352 - 8. You may not copy, modify, sublicense, link with, or distribute
2.353 -the Library except as expressly provided under this License. Any
2.354 -attempt otherwise to copy, modify, sublicense, link with, or
2.355 -distribute the Library is void, and will automatically terminate your
2.356 -rights under this License. However, parties who have received copies,
2.357 -or rights, from you under this License will not have their licenses
2.358 -terminated so long as such parties remain in full compliance.
2.359 -
2.360 - 9. You are not required to accept this License, since you have not
2.361 -signed it. However, nothing else grants you permission to modify or
2.362 -distribute the Library or its derivative works. These actions are
2.363 -prohibited by law if you do not accept this License. Therefore, by
2.364 -modifying or distributing the Library (or any work based on the
2.365 -Library), you indicate your acceptance of this License to do so, and
2.366 -all its terms and conditions for copying, distributing or modifying
2.367 -the Library or works based on it.
2.368 -
2.369 - 10. Each time you redistribute the Library (or any work based on the
2.370 -Library), the recipient automatically receives a license from the
2.371 -original licensor to copy, distribute, link with or modify the Library
2.372 -subject to these terms and conditions. You may not impose any further
2.373 -restrictions on the recipients' exercise of the rights granted herein.
2.374 -You are not responsible for enforcing compliance by third parties with
2.375 -this License.
2.376 -
2.377 - 11. If, as a consequence of a court judgment or allegation of patent
2.378 -infringement or for any other reason (not limited to patent issues),
2.379 -conditions are imposed on you (whether by court order, agreement or
2.380 -otherwise) that contradict the conditions of this License, they do not
2.381 -excuse you from the conditions of this License. If you cannot
2.382 -distribute so as to satisfy simultaneously your obligations under this
2.383 -License and any other pertinent obligations, then as a consequence you
2.384 -may not distribute the Library at all. For example, if a patent
2.385 -license would not permit royalty-free redistribution of the Library by
2.386 -all those who receive copies directly or indirectly through you, then
2.387 -the only way you could satisfy both it and this License would be to
2.388 -refrain entirely from distribution of the Library.
2.389 -
2.390 -If any portion of this section is held invalid or unenforceable under any
2.391 -particular circumstance, the balance of the section is intended to apply,
2.392 -and the section as a whole is intended to apply in other circumstances.
2.393 -
2.394 -It is not the purpose of this section to induce you to infringe any
2.395 -patents or other property right claims or to contest validity of any
2.396 -such claims; this section has the sole purpose of protecting the
2.397 -integrity of the free software distribution system which is
2.398 -implemented by public license practices. Many people have made
2.399 -generous contributions to the wide range of software distributed
2.400 -through that system in reliance on consistent application of that
2.401 -system; it is up to the author/donor to decide if he or she is willing
2.402 -to distribute software through any other system and a licensee cannot
2.403 -impose that choice.
2.404 -
2.405 -This section is intended to make thoroughly clear what is believed to
2.406 -be a consequence of the rest of this License.
2.407 -
2.408 - 12. If the distribution and/or use of the Library is restricted in
2.409 -certain countries either by patents or by copyrighted interfaces, the
2.410 -original copyright holder who places the Library under this License may add
2.411 -an explicit geographical distribution limitation excluding those countries,
2.412 -so that distribution is permitted only in or among countries not thus
2.413 -excluded. In such case, this License incorporates the limitation as if
2.414 -written in the body of this License.
2.415 -
2.416 - 13. The Free Software Foundation may publish revised and/or new
2.417 -versions of the Lesser General Public License from time to time.
2.418 -Such new versions will be similar in spirit to the present version,
2.419 -but may differ in detail to address new problems or concerns.
2.420 -
2.421 -Each version is given a distinguishing version number. If the Library
2.422 -specifies a version number of this License which applies to it and
2.423 -"any later version", you have the option of following the terms and
2.424 -conditions either of that version or of any later version published by
2.425 -the Free Software Foundation. If the Library does not specify a
2.426 -license version number, you may choose any version ever published by
2.427 -the Free Software Foundation.

3.4 + GNU GENERAL PUBLIC LICENSE
3.5 + Version 3, 29 June 2007
3.6 +
3.7 + Copyright (C) 2007 Free Software Foundation, Inc. <http://fsf.org/>
3.8 + Everyone is permitted to copy and distribute verbatim copies
3.9 + of this license document, but changing it is not allowed.
3.10 +
3.11 + Preamble
3.12 +
3.13 + The GNU General Public License is a free, copyleft license for
3.14 +software and other kinds of works.
3.15 +
3.16 + The licenses for most software and other practical works are designed
3.17 +to take away your freedom to share and change the works. By contrast,
3.18 +the GNU General Public License is intended to guarantee your freedom to
3.19 +share and change all versions of a program--to make sure it remains free
3.20 +software for all its users. We, the Free Software Foundation, use the
3.21 +GNU General Public License for most of our software; it applies also to
3.22 +any other work released this way by its authors. You can apply it to
3.23 +your programs, too.
3.24 +
3.25 + When we speak of free software, we are referring to freedom, not
3.26 +price. Our General Public Licenses are designed to make sure that you
3.27 +have the freedom to distribute copies of free software (and charge for
3.28 +them if you wish), that you receive source code or can get it if you
3.29 +want it, that you can change the software or use pieces of it in new
3.30 +free programs, and that you know you can do these things.
3.31 +
3.32 + To protect your rights, we need to prevent others from denying you
3.33 +these rights or asking you to surrender the rights. Therefore, you have
3.34 +certain responsibilities if you distribute copies of the software, or if
3.35 +you modify it: responsibilities to respect the freedom of others.
3.36 +
3.37 + For example, if you distribute copies of such a program, whether
3.38 +gratis or for a fee, you must pass on to the recipients the same
3.39 +freedoms that you received. You must make sure that they, too, receive
3.40 +or can get the source code. And you must show them these terms so they
3.41 +know their rights.
3.42 +
3.43 + Developers that use the GNU GPL protect your rights with two steps:
3.44 +(1) assert copyright on the software, and (2) offer you this License
3.45 +giving you legal permission to copy, distribute and/or modify it.
3.46 +
3.47 + For the developers' and authors' protection, the GPL clearly explains
3.48 +that there is no warranty for this free software. For both users' and
3.49 +authors' sake, the GPL requires that modified versions be marked as
3.50 +changed, so that their problems will not be attributed erroneously to
3.51 +authors of previous versions.
3.52 +
3.53 + Some devices are designed to deny users access to install or run
3.54 +modified versions of the software inside them, although the manufacturer
3.55 +can do so. This is fundamentally incompatible with the aim of
3.56 +protecting users' freedom to change the software. The systematic
3.57 +pattern of such abuse occurs in the area of products for individuals to
3.58 +use, which is precisely where it is most unacceptable. Therefore, we
3.59 +have designed this version of the GPL to prohibit the practice for those
3.60 +products. If such problems arise substantially in other domains, we
3.61 +stand ready to extend this provision to those domains in future versions
3.62 +of the GPL, as needed to protect the freedom of users.
3.63 +
3.64 + Finally, every program is threatened constantly by software patents.
3.65 +States should not allow patents to restrict development and use of
3.66 +software on general-purpose computers, but in those that do, we wish to
3.67 +avoid the special danger that patents applied to a free program could
3.68 +make it effectively proprietary. To prevent this, the GPL assures that
3.69 +patents cannot be used to render the program non-free.
3.70 +
3.71 + The precise terms and conditions for copying, distribution and
3.72 +modification follow.
3.73 +
3.74 + TERMS AND CONDITIONS
3.75 +
3.76 + 0. Definitions.
3.77 +
3.78 + "This License" refers to version 3 of the GNU General Public License.
3.79 +
3.80 + "Copyright" also means copyright-like laws that apply to other kinds of
3.81 +works, such as semiconductor masks.
3.82 +
3.83 + "The Program" refers to any copyrightable work licensed under this
3.84 +License. Each licensee is addressed as "you". "Licensees" and
3.85 +"recipients" may be individuals or organizations.
3.86 +
3.87 + To "modify" a work means to copy from or adapt all or part of the work
3.88 +in a fashion requiring copyright permission, other than the making of an
3.89 +exact copy. The resulting work is called a "modified version" of the
3.90 +earlier work or a work "based on" the earlier work.
3.91 +
3.92 + A "covered work" means either the unmodified Program or a work based
3.93 +on the Program.
3.94 +
3.95 + To "propagate" a work means to do anything with it that, without
3.96 +permission, would make you directly or secondarily liable for
3.97 +infringement under applicable copyright law, except executing it on a
3.98 +computer or modifying a private copy. Propagation includes copying,
3.99 +distribution (with or without modification), making available to the
3.100 +public, and in some countries other activities as well.
3.101 +
3.102 + To "convey" a work means any kind of propagation that enables other
3.103 +parties to make or receive copies. Mere interaction with a user through
3.104 +a computer network, with no transfer of a copy, is not conveying.
3.105 +
3.106 + An interactive user interface displays "Appropriate Legal Notices"
3.107 +to the extent that it includes a convenient and prominently visible
3.108 +feature that (1) displays an appropriate copyright notice, and (2)
3.109 +tells the user that there is no warranty for the work (except to the
3.110 +extent that warranties are provided), that licensees may convey the
3.111 +work under this License, and how to view a copy of this License. If
3.112 +the interface presents a list of user commands or options, such as a
3.113 +menu, a prominent item in the list meets this criterion.
3.114 +
3.115 + 1. Source Code.
3.116 +
3.117 + The "source code" for a work means the preferred form of the work
3.118 +for making modifications to it. "Object code" means any non-source
3.119 +form of a work.
3.120 +
3.121 + A "Standard Interface" means an interface that either is an official
3.122 +standard defined by a recognized standards body, or, in the case of
3.123 +interfaces specified for a particular programming language, one that
3.124 +is widely used among developers working in that language.
3.125 +
3.126 + The "System Libraries" of an executable work include anything, other
3.127 +than the work as a whole, that (a) is included in the normal form of
3.128 +packaging a Major Component, but which is not part of that Major
3.129 +Component, and (b) serves only to enable use of the work with that
3.130 +Major Component, or to implement a Standard Interface for which an
3.131 +implementation is available to the public in source code form. A
3.132 +"Major Component", in this context, means a major essential component
3.133 +(kernel, window system, and so on) of the specific operating system
3.134 +(if any) on which the executable work runs, or a compiler used to
3.135 +produce the work, or an object code interpreter used to run it.
3.136 +
3.137 + The "Corresponding Source" for a work in object code form means all
3.138 +the source code needed to generate, install, and (for an executable
3.139 +work) run the object code and to modify the work, including scripts to
3.140 +control those activities. However, it does not include the work's
3.141 +System Libraries, or general-purpose tools or generally available free
3.142 +programs which are used unmodified in performing those activities but
3.143 +which are not part of the work. For example, Corresponding Source
3.144 +includes interface definition files associated with source files for
3.145 +the work, and the source code for shared libraries and dynamically
3.146 +linked subprograms that the work is specifically designed to require,
3.147 +such as by intimate data communication or control flow between those
3.148 +subprograms and other parts of the work.
3.149 +
3.150 + The Corresponding Source need not include anything that users
3.151 +can regenerate automatically from other parts of the Corresponding
3.152 +Source.
3.153 +
3.154 + The Corresponding Source for a work in source code form is that
3.155 +same work.
3.156 +
3.157 + 2. Basic Permissions.
3.158 +
3.159 + All rights granted under this License are granted for the term of
3.160 +copyright on the Program, and are irrevocable provided the stated
3.161 +conditions are met. This License explicitly affirms your unlimited
3.162 +permission to run the unmodified Program. The output from running a
3.163 +covered work is covered by this License only if the output, given its
3.164 +content, constitutes a covered work. This License acknowledges your
3.165 +rights of fair use or other equivalent, as provided by copyright law.
3.166 +
3.167 + You may make, run and propagate covered works that you do not
3.168 +convey, without conditions so long as your license otherwise remains
3.169 +in force. You may convey covered works to others for the sole purpose
3.170 +of having them make modifications exclusively for you, or provide you
3.171 +with facilities for running those works, provided that you comply with
3.172 +the terms of this License in conveying all material for which you do
3.173 +not control copyright. Those thus making or running the covered works
3.174 +for you must do so exclusively on your behalf, under your direction
3.175 +and control, on terms that prohibit them from making any copies of
3.176 +your copyrighted material outside their relationship with you.
3.177 +
3.178 + Conveying under any other circumstances is permitted solely under
3.179 +the conditions stated below. Sublicensing is not allowed; section 10
3.180 +makes it unnecessary.
3.181 +
3.182 + 3. Protecting Users' Legal Rights From Anti-Circumvention Law.
3.183 +
3.184 + No covered work shall be deemed part of an effective technological
3.185 +measure under any applicable law fulfilling obligations under article
3.186 +11 of the WIPO copyright treaty adopted on 20 December 1996, or
3.187 +similar laws prohibiting or restricting circumvention of such
3.188 +measures.
3.189 +
3.190 + When you convey a covered work, you waive any legal power to forbid
3.191 +circumvention of technological measures to the extent such circumvention
3.192 +is effected by exercising rights under this License with respect to
3.193 +the covered work, and you disclaim any intention to limit operation or
3.194 +modification of the work as a means of enforcing, against the work's
3.195 +users, your or third parties' legal rights to forbid circumvention of
3.196 +technological measures.
3.197 +
3.198 + 4. Conveying Verbatim Copies.
3.199 +
3.200 + You may convey verbatim copies of the Program's source code as you
3.201 +receive it, in any medium, provided that you conspicuously and
3.202 +appropriately publish on each copy an appropriate copyright notice;
3.203 +keep intact all notices stating that this License and any
3.204 +non-permissive terms added in accord with section 7 apply to the code;
3.205 +keep intact all notices of the absence of any warranty; and give all
3.206 +recipients a copy of this License along with the Program.
3.207 +
3.208 + You may charge any price or no price for each copy that you convey,
3.209 +and you may offer support or warranty protection for a fee.
3.210 +
3.211 + 5. Conveying Modified Source Versions.
3.212 +
3.213 + You may convey a work based on the Program, or the modifications to
3.214 +produce it from the Program, in the form of source code under the
3.215 +terms of section 4, provided that you also meet all of these conditions:
3.216 +
3.217 + a) The work must carry prominent notices stating that you modified
3.218 + it, and giving a relevant date.
3.219 +
3.220 + b) The work must carry prominent notices stating that it is
3.221 + released under this License and any conditions added under section
3.222 + 7. This requirement modifies the requirement in section 4 to
3.223 + "keep intact all notices".
3.224 +
3.225 + c) You must license the entire work, as a whole, under this
3.226 + License to anyone who comes into possession of a copy. This
3.227 + License will therefore apply, along with any applicable section 7
3.228 + additional terms, to the whole of the work, and all its parts,
3.229 + regardless of how they are packaged. This License gives no
3.230 + permission to license the work in any other way, but it does not
3.231 + invalidate such permission if you have separately received it.
3.232 +
3.233 + d) If the work has interactive user interfaces, each must display
3.234 + Appropriate Legal Notices; however, if the Program has interactive
3.235 + interfaces that do not display Appropriate Legal Notices, your
3.236 + work need not make them do so.
3.237 +
3.238 + A compilation of a covered work with other separate and independent
3.239 +works, which are not by their nature extensions of the covered work,
3.240 +and which are not combined with it such as to form a larger program,
3.241 +in or on a volume of a storage or distribution medium, is called an
3.242 +"aggregate" if the compilation and its resulting copyright are not
3.243 +used to limit the access or legal rights of the compilation's users
3.244 +beyond what the individual works permit. Inclusion of a covered work
3.245 +in an aggregate does not cause this License to apply to the other
3.246 +parts of the aggregate.
3.247 +
3.248 + 6. Conveying Non-Source Forms.
3.249 +
3.250 + You may convey a covered work in object code form under the terms
3.251 +of sections 4 and 5, provided that you also convey the
3.252 +machine-readable Corresponding Source under the terms of this License,
3.253 +in one of these ways:
3.254 +
3.255 + a) Convey the object code in, or embodied in, a physical product
3.256 + (including a physical distribution medium), accompanied by the
3.257 + Corresponding Source fixed on a durable physical medium
3.258 + customarily used for software interchange.
3.259 +
3.260 + b) Convey the object code in, or embodied in, a physical product
3.261 + (including a physical distribution medium), accompanied by a
3.262 + written offer, valid for at least three years and valid for as
3.263 + long as you offer spare parts or customer support for that product
3.264 + model, to give anyone who possesses the object code either (1) a
3.265 + copy of the Corresponding Source for all the software in the
3.266 + product that is covered by this License, on a durable physical
3.267 + medium customarily used for software interchange, for a price no
3.268 + more than your reasonable cost of physically performing this
3.269 + conveying of source, or (2) access to copy the
3.270 + Corresponding Source from a network server at no charge.
3.271 +
3.272 + c) Convey individual copies of the object code with a copy of the
3.273 + written offer to provide the Corresponding Source. This
3.274 + alternative is allowed only occasionally and noncommercially, and
3.275 + only if you received the object code with such an offer, in accord
3.276 + with subsection 6b.
3.277 +
3.278 + d) Convey the object code by offering access from a designated
3.279 + place (gratis or for a charge), and offer equivalent access to the
3.280 + Corresponding Source in the same way through the same place at no
3.281 + further charge. You need not require recipients to copy the
3.282 + Corresponding Source along with the object code. If the place to
3.283 + copy the object code is a network server, the Corresponding Source
3.284 + may be on a different server (operated by you or a third party)
3.285 + that supports equivalent copying facilities, provided you maintain
3.286 + clear directions next to the object code saying where to find the
3.287 + Corresponding Source. Regardless of what server hosts the
3.288 + Corresponding Source, you remain obligated to ensure that it is
3.289 + available for as long as needed to satisfy these requirements.
3.290 +
3.291 + e) Convey the object code using peer-to-peer transmission, provided
3.292 + you inform other peers where the object code and Corresponding
3.293 + Source of the work are being offered to the general public at no
3.294 + charge under subsection 6d.
3.295 +
3.296 + A separable portion of the object code, whose source code is excluded
3.297 +from the Corresponding Source as a System Library, need not be
3.298 +included in conveying the object code work.
3.299 +
3.300 + A "User Product" is either (1) a "consumer product", which means any
3.301 +tangible personal property which is normally used for personal, family,
3.302 +or household purposes, or (2) anything designed or sold for incorporation
3.303 +into a dwelling. In determining whether a product is a consumer product,
3.304 +doubtful cases shall be resolved in favor of coverage. For a particular
3.305 +product received by a particular user, "normally used" refers to a
3.306 +typical or common use of that class of product, regardless of the status
3.307 +of the particular user or of the way in which the particular user
3.308 +actually uses, or expects or is expected to use, the product. A product
3.309 +is a consumer product regardless of whether the product has substantial
3.310 +commercial, industrial or non-consumer uses, unless such uses represent
3.311 +the only significant mode of use of the product.
3.312 +
3.313 + "Installation Information" for a User Product means any methods,
3.314 +procedures, authorization keys, or other information required to install
3.315 +and execute modified versions of a covered work in that User Product from
3.316 +a modified version of its Corresponding Source. The information must
3.317 +suffice to ensure that the continued functioning of the modified object
3.318 +code is in no case prevented or interfered with solely because
3.319 +modification has been made.
3.320 +
3.321 + If you convey an object code work under this section in, or with, or
3.322 +specifically for use in, a User Product, and the conveying occurs as
3.323 +part of a transaction in which the right of possession and use of the
3.324 +User Product is transferred to the recipient in perpetuity or for a
3.325 +fixed term (regardless of how the transaction is characterized), the
3.326 +Corresponding Source conveyed under this section must be accompanied
3.327 +by the Installation Information. But this requirement does not apply
3.328 +if neither you nor any third party retains the ability to install
3.329 +modified object code on the User Product (for example, the work has
3.330 +been installed in ROM).
3.331 +
3.332 + The requirement to provide Installation Information does not include a
3.333 +requirement to continue to provide support service, warranty, or updates
3.334 +for a work that has been modified or installed by the recipient, or for
3.335 +the User Product in which it has been modified or installed. Access to a
3.336 +network may be denied when the modification itself materially and
3.337 +adversely affects the operation of the network or violates the rules and
3.338 +protocols for communication across the network.
3.339 +
3.340 + Corresponding Source conveyed, and Installation Information provided,
3.341 +in accord with this section must be in a format that is publicly
3.342 +documented (and with an implementation available to the public in
3.343 +source code form), and must require no special password or key for
3.344 +unpacking, reading or copying.
3.345 +
3.346 + 7. Additional Terms.
3.347 +
3.348 + "Additional permissions" are terms that supplement the terms of this
3.349 +License by making exceptions from one or more of its conditions.
3.350 +Additional permissions that are applicable to the entire Program shall
3.351 +be treated as though they were included in this License, to the extent
3.352 +that they are valid under applicable law. If additional permissions
3.353 +apply only to part of the Program, that part may be used separately
3.354 +under those permissions, but the entire Program remains governed by
3.355 +this License without regard to the additional permissions.
3.356 +
3.357 + When you convey a copy of a covered work, you may at your option
3.358 +remove any additional permissions from that copy, or from any part of
3.359 +it. (Additional permissions may be written to require their own
3.360 +removal in certain cases when you modify the work.) You may place
3.361 +additional permissions on material, added by you to a covered work,
3.362 +for which you have or can give appropriate copyright permission.
3.363 +
3.364 + Notwithstanding any other provision of this License, for material you
3.365 +add to a covered work, you may (if authorized by the copyright holders of
3.366 +that material) supplement the terms of this License with terms:
3.367 +
3.368 + a) Disclaiming warranty or limiting liability differently from the
3.369 + terms of sections 15 and 16 of this License; or
3.370 +
3.371 + b) Requiring preservation of specified reasonable legal notices or
3.372 + author attributions in that material or in the Appropriate Legal
3.373 + Notices displayed by works containing it; or
3.374 +
3.375 + c) Prohibiting misrepresentation of the origin of that material, or
3.376 + requiring that modified versions of such material be marked in
3.377 + reasonable ways as different from the original version; or
3.378 +
3.379 + d) Limiting the use for publicity purposes of names of licensors or
3.380 + authors of the material; or
3.381 +
3.382 + e) Declining to grant rights under trademark law for use of some
3.383 + trade names, trademarks, or service marks; or
3.384 +
3.385 + f) Requiring indemnification of licensors and authors of that
3.386 + material by anyone who conveys the material (or modified versions of
3.387 + it) with contractual assumptions of liability to the recipient, for
3.388 + any liability that these contractual assumptions directly impose on
3.389 + those licensors and authors.
3.390 +
3.391 + All other non-permissive additional terms are considered "further
3.392 +restrictions" within the meaning of section 10. If the Program as you
3.393 +received it, or any part of it, contains a notice stating that it is
3.394 +governed by this License along with a term that is a further
3.395 +restriction, you may remove that term. If a license document contains
3.396 +a further restriction but permits relicensing or conveying under this
3.397 +License, you may add to a covered work material governed by the terms
3.398 +of that license document, provided that the further restriction does
3.399 +not survive such relicensing or conveying.
3.400 +
3.401 + If you add terms to a covered work in accord with this section, you
3.402 +must place, in the relevant source files, a statement of the
3.403 +additional terms that apply to those files, or a notice indicating
3.404 +where to find the applicable terms.
3.405 +
3.406 + Additional terms, permissive or non-permissive, may be stated in the
3.407 +form of a separately written license, or stated as exceptions;
3.408 +the above requirements apply either way.
3.409 +
3.410 + 8. Termination.
3.411 +
3.412 + You may not propagate or modify a covered work except as expressly
3.413 +provided under this License. Any attempt otherwise to propagate or
3.414 +modify it is void, and will automatically terminate your rights under
3.415 +this License (including any patent licenses granted under the third
3.416 +paragraph of section 11).
3.417 +
3.418 + However, if you cease all violation of this License, then your
3.419 +license from a particular copyright holder is reinstated (a)
3.420 +provisionally, unless and until the copyright holder explicitly and
3.421 +finally terminates your license, and (b) permanently, if the copyright
3.422 +holder fails to notify you of the violation by some reasonable means
3.423 +prior to 60 days after the cessation.
3.424 +
3.425 + Moreover, your license from a particular copyright holder is
3.426 +reinstated permanently if the copyright holder notifies you of the
3.427 +violation by some reasonable means, this is the first time you have
3.428 +received notice of violation of this License (for any work) from that
3.429 +copyright holder, and you cure the violation prior to 30 days after
3.430 +your receipt of the notice.
3.431 +
3.432 + Termination of your rights under this section does not terminate the
3.433 +licenses of parties who have received copies or rights from you under
3.434 +this License. If your rights have been terminated and not permanently
3.435 +reinstated, you do not qualify to receive new licenses for the same
3.436 +material under section 10.
3.437 +
3.438 + 9. Acceptance Not Required for Having Copies.
3.439 +
3.440 + You are not required to accept this License in order to receive or
3.441 +run a copy of the Program. Ancillary propagation of a covered work
3.442 +occurring solely as a consequence of using peer-to-peer transmission
3.443 +to receive a copy likewise does not require acceptance. However,
3.444 +nothing other than this License grants you permission to propagate or
3.445 +modify any covered work. These actions infringe copyright if you do
3.446 +not accept this License. Therefore, by modifying or propagating a
3.447 +covered work, you indicate your acceptance of this License to do so.
3.448 +
3.449 + 10. Automatic Licensing of Downstream Recipients.
3.450 +
3.451 + Each time you convey a covered work, the recipient automatically
3.452 +receives a license from the original licensors, to run, modify and
3.453 +propagate that work, subject to this License. You are not responsible
3.454 +for enforcing compliance by third parties with this License.
3.455 +
3.456 + An "entity transaction" is a transaction transferring control of an
3.457 +organization, or substantially all assets of one, or subdividing an
3.458 +organization, or merging organizations. If propagation of a covered
3.459 +work results from an entity transaction, each party to that
3.460 +transaction who receives a copy of the work also receives whatever
3.461 +licenses to the work the party's predecessor in interest had or could
3.462 +give under the previous paragraph, plus a right to possession of the
3.463 +Corresponding Source of the work from the predecessor in interest, if
3.464 +the predecessor has it or can get it with reasonable efforts.
3.465 +
3.466 + You may not impose any further restrictions on the exercise of the
3.467 +rights granted or affirmed under this License. For example, you may
3.468 +not impose a license fee, royalty, or other charge for exercise of
3.469 +rights granted under this License, and you may not initiate litigation
3.470 +(including a cross-claim or counterclaim in a lawsuit) alleging that
3.471 +any patent claim is infringed by making, using, selling, offering for
3.472 +sale, or importing the Program or any portion of it.
3.473 +
3.474 + 11. Patents.
3.475 +
3.476 + A "contributor" is a copyright holder who authorizes use under this
3.477 +License of the Program or a work on which the Program is based. The
3.478 +work thus licensed is called the contributor's "contributor version".
3.479 +
3.480 + A contributor's "essential patent claims" are all patent claims
3.481 +owned or controlled by the contributor, whether already acquired or
3.482 +hereafter acquired, that would be infringed by some manner, permitted
3.483 +by this License, of making, using, or selling its contributor version,
3.484 +but do not include claims that would be infringed only as a
3.485 +consequence of further modification of the contributor version. For
3.486 +purposes of this definition, "control" includes the right to grant
3.487 +patent sublicenses in a manner consistent with the requirements of
3.488 +this License.
3.489 +
3.490 + Each contributor grants you a non-exclusive, worldwide, royalty-free
3.491 +patent license under the contributor's essential patent claims, to
3.492 +make, use, sell, offer for sale, import and otherwise run, modify and
3.493 +propagate the contents of its contributor version.
3.494 +
3.495 + In the following three paragraphs, a "patent license" is any express
3.496 +agreement or commitment, however denominated, not to enforce a patent
3.497 +(such as an express permission to practice a patent or covenant not to
3.498 +sue for patent infringement). To "grant" such a patent license to a
3.499 +party means to make such an agreement or commitment not to enforce a
3.500 +patent against the party.
3.501 +
3.502 + If you convey a covered work, knowingly relying on a patent license,
3.503 +and the Corresponding Source of the work is not available for anyone
3.504 +to copy, free of charge and under the terms of this License, through a
3.505 +publicly available network server or other readily accessible means,
3.506 +then you must either (1) cause the Corresponding Source to be so
3.507 +available, or (2) arrange to deprive yourself of the benefit of the
3.508 +patent license for this particular work, or (3) arrange, in a manner
3.509 +consistent with the requirements of this License, to extend the patent
3.510 +license to downstream recipients. "Knowingly relying" means you have
3.511 +actual knowledge that, but for the patent license, your conveying the
3.512 +covered work in a country, or your recipient's use of the covered work
3.513 +in a country, would infringe one or more identifiable patents in that
3.514 +country that you have reason to believe are valid.
3.515 +
3.516 + If, pursuant to or in connection with a single transaction or
3.517 +arrangement, you convey, or propagate by procuring conveyance of, a
3.518 +covered work, and grant a patent license to some of the parties
3.519 +receiving the covered work authorizing them to use, propagate, modify
3.520 +or convey a specific copy of the covered work, then the patent license
3.521 +you grant is automatically extended to all recipients of the covered
3.522 +work and works based on it.
3.523 +
3.524 + A patent license is "discriminatory" if it does not include within
3.525 +the scope of its coverage, prohibits the exercise of, or is
3.526 +conditioned on the non-exercise of one or more of the rights that are
3.527 +specifically granted under this License. You may not convey a covered
3.528 +work if you are a party to an arrangement with a third party that is
3.529 +in the business of distributing software, under which you make payment
3.530 +to the third party based on the extent of your activity of conveying
3.531 +the work, and under which the third party grants, to any of the
3.532 +parties who would receive the covered work from you, a discriminatory
3.533 +patent license (a) in connection with copies of the covered work
3.534 +conveyed by you (or copies made from those copies), or (b) primarily
3.535 +for and in connection with specific products or compilations that
3.536 +contain the covered work, unless you entered into that arrangement,
3.537 +or that patent license was granted, prior to 28 March 2007.
3.538 +
3.539 + Nothing in this License shall be construed as excluding or limiting
3.540 +any implied license or other defenses to infringement that may
3.541 +otherwise be available to you under applicable patent law.
3.542 +
3.543 + 12. No Surrender of Others' Freedom.
3.544 +
3.545 + If conditions are imposed on you (whether by court order, agreement or
3.546 +otherwise) that contradict the conditions of this License, they do not
3.547 +excuse you from the conditions of this License. If you cannot convey a
3.548 +covered work so as to satisfy simultaneously your obligations under this
3.549 +License and any other pertinent obligations, then as a consequence you may
3.550 +not convey it at all. For example, if you agree to terms that obligate you
3.551 +to collect a royalty for further conveying from those to whom you convey
3.552 +the Program, the only way you could satisfy both those terms and this
3.553 +License would be to refrain entirely from conveying the Program.
3.554 +
3.555 + 13. Use with the GNU Affero General Public License.
3.556 +
3.557 + Notwithstanding any other provision of this License, you have
3.558 +permission to link or combine any covered work with a work licensed
3.559 +under version 3 of the GNU Affero General Public License into a single
3.560 +combined work, and to convey the resulting work. The terms of this
3.561 +License will continue to apply to the part which is the covered work,
3.562 +but the special requirements of the GNU Affero General Public License,
3.563 +section 13, concerning interaction through a network will apply to the
3.564 +combination as such.
3.565 +
3.566 + 14. Revised Versions of this License.
3.567 +
3.568 + The Free Software Foundation may publish revised and/or new versions of
3.569 +the GNU General Public License from time to time. Such new versions will
3.570 +be similar in spirit to the present version, but may differ in detail to
3.571 +address new problems or concerns.
3.572 +
3.573 + Each version is given a distinguishing version number. If the
3.574 +Program specifies that a certain numbered version of the GNU General
3.575 +Public License "or any later version" applies to it, you have the
3.576 +option of following the terms and conditions either of that numbered
3.577 +version or of any later version published by the Free Software
3.578 +Foundation. If the Program does not specify a version number of the
3.579 +GNU General Public License, you may choose any version ever published
3.580 +by the Free Software Foundation.
3.581 +
3.582 + If the Program specifies that a proxy can decide which future
3.583 +versions of the GNU General Public License can be used, that proxy's
3.584 +public statement of acceptance of a version permanently authorizes you
3.585 +to choose that version for the Program.
3.586 +
3.587 + Later license versions may give you additional or different
3.588 +permissions. However, no additional obligations are imposed on any
3.589 +author or copyright holder as a result of your choosing to follow a
3.590 +later version.
3.591 +
3.592 + 15. Disclaimer of Warranty.
3.593 +
3.594 + THERE IS NO WARRANTY FOR THE PROGRAM, TO THE EXTENT PERMITTED BY
3.595 +APPLICABLE LAW. EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT
3.596 +HOLDERS AND/OR OTHER PARTIES PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY
3.597 +OF ANY KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO,
3.598 +THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR
3.599 +PURPOSE. THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE PROGRAM
3.600 +IS WITH YOU. SHOULD THE PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF
3.601 +ALL NECESSARY SERVICING, REPAIR OR CORRECTION.
3.602 +
3.603 + 16. Limitation of Liability.
3.604 +
3.605 + IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
3.606 +WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MODIFIES AND/OR CONVEYS
3.607 +THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, INCLUDING ANY
3.608 +GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING OUT OF THE
3.609 +USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED TO LOSS OF
3.610 +DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD
3.611 +PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER PROGRAMS),
3.612 +EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF
3.613 +SUCH DAMAGES.
3.614 +
3.615 + 17. Interpretation of Sections 15 and 16.
3.616 +
3.617 + If the disclaimer of warranty and limitation of liability provided
3.618 +above cannot be given local legal effect according to their terms,
3.619 +reviewing courts shall apply local law that most closely approximates
3.620 +an absolute waiver of all civil liability in connection with the
3.621 +Program, unless a warranty or assumption of liability accompanies a
3.622 +copy of the Program in return for a fee.
3.623 +
3.624 + END OF TERMS AND CONDITIONS
3.625 +
3.626 + How to Apply These Terms to Your New Programs
3.627 +
3.628 + If you develop a new program, and you want it to be of the greatest
3.629 +possible use to the public, the best way to achieve this is to make it
3.630 +free software which everyone can redistribute and change under these terms.
3.631 +
3.632 + To do so, attach the following notices to the program. It is safest
3.633 +to attach them to the start of each source file to most effectively
3.634 +state the exclusion of warranty; and each file should have at least
3.635 +the "copyright" line and a pointer to where the full notice is found.
3.636 +
3.637 + <one line to give the program's name and a brief idea of what it does.>
3.638 + Copyright (C) <year> <name of author>
3.639 +
3.640 + This program is free software: you can redistribute it and/or modify
3.641 + it under the terms of the GNU General Public License as published by
3.642 + the Free Software Foundation, either version 3 of the License, or
3.643 + (at your option) any later version.
3.644 +
3.645 + This program is distributed in the hope that it will be useful,
3.646 + but WITHOUT ANY WARRANTY; without even the implied warranty of
3.647 + MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the
3.648 + GNU General Public License for more details.
3.649 +
3.650 + You should have received a copy of the GNU General Public License
3.651 + along with this program. If not, see <http://www.gnu.org/licenses/>.
3.652 +
3.653 +Also add information on how to contact you by electronic and paper mail.
3.654 +
3.655 + If the program does terminal interaction, make it output a short
3.656 +notice like this when it starts in an interactive mode:
3.657 +
3.658 + <program> Copyright (C) <year> <name of author>
3.659 + This program comes with ABSOLUTELY NO WARRANTY; for details type `show w'.
3.660 + This is free software, and you are welcome to redistribute it
3.661 + under certain conditions; type `show c' for details.
3.662 +
3.663 +The hypothetical commands `show w' and `show c' should show the appropriate
3.664 +parts of the General Public License. Of course, your program's commands
3.665 +might be different; for a GUI interface, you would use an "about box".
3.666 +
3.667 + You should also get your employer (if you work as a programmer) or school,
3.668 +if any, to sign a "copyright disclaimer" for the program, if necessary.
3.669 +For more information on this, and how to apply and follow the GNU GPL, see
3.670 +<http://www.gnu.org/licenses/>.
3.671 +
3.672 + The GNU General Public License does not permit incorporating your program
3.673 +into proprietary programs. If your program is a subroutine library, you
3.674 +may consider it more useful to permit linking proprietary applications with
3.675 +the library. If this is what you want to do, use the GNU Lesser General
3.676 +Public License instead of this License. But first, please read
3.677 +<http://www.gnu.org/philosophy/why-not-lgpl.html>.
