| 1 | + GNU GENERAL PUBLIC LICENSE |
| 2 | + Version 3, 29 June 2007 |
| 3 | + |
| 4 | + Copyright (C) 2007 Free Software Foundation, Inc. <http://fsf.org/> |
| 5 | + Everyone is permitted to copy and distribute verbatim copies |
| 6 | + of this license document, but changing it is not allowed. |
| 7 | + |
| 8 | + Preamble |
| 9 | + |
| 10 | + The GNU General Public License is a free, copyleft license for |
| 11 | +software and other kinds of works. |
| 12 | + |
| 13 | + The licenses for most software and other practical works are designed |
| 14 | +to take away your freedom to share and change the works. By contrast, |
| 15 | +the GNU General Public License is intended to guarantee your freedom to |
| 16 | +share and change all versions of a program--to make sure it remains free |
| 17 | +software for all its users. We, the Free Software Foundation, use the |
| 18 | +GNU General Public License for most of our software; it applies also to |
| 19 | +any other work released this way by its authors. You can apply it to |
| 20 | +your programs, too. |
| 21 | + |
| 22 | + When we speak of free software, we are referring to freedom, not |
| 23 | +price. Our General Public Licenses are designed to make sure that you |
| 24 | +have the freedom to distribute copies of free software (and charge for |
| 25 | +them if you wish), that you receive source code or can get it if you |
| 26 | +want it, that you can change the software or use pieces of it in new |
| 27 | +free programs, and that you know you can do these things. |
| 28 | + |
| 29 | + To protect your rights, we need to prevent others from denying you |
| 30 | +these rights or asking you to surrender the rights. Therefore, you have |
| 31 | +certain responsibilities if you distribute copies of the software, or if |
| 32 | +you modify it: responsibilities to respect the freedom of others. |
| 33 | + |
| 34 | + For example, if you distribute copies of such a program, whether |
| 35 | +gratis or for a fee, you must pass on to the recipients the same |
| 36 | +freedoms that you received. You must make sure that they, too, receive |
| 37 | +or can get the source code. And you must show them these terms so they |
| 38 | +know their rights. |
| 39 | + |
| 40 | + Developers that use the GNU GPL protect your rights with two steps: |
| 41 | +(1) assert copyright on the software, and (2) offer you this License |
| 42 | +giving you legal permission to copy, distribute and/or modify it. |
| 43 | + |
| 44 | + For the developers' and authors' protection, the GPL clearly explains |
| 45 | +that there is no warranty for this free software. For both users' and |
| 46 | +authors' sake, the GPL requires that modified versions be marked as |
| 47 | +changed, so that their problems will not be attributed erroneously to |
| 48 | +authors of previous versions. |
| 49 | + |
| 50 | + Some devices are designed to deny users access to install or run |
| 51 | +modified versions of the software inside them, although the manufacturer |
| 52 | +can do so. This is fundamentally incompatible with the aim of |
| 53 | +protecting users' freedom to change the software. The systematic |
| 54 | +pattern of such abuse occurs in the area of products for individuals to |
| 55 | +use, which is precisely where it is most unacceptable. Therefore, we |
| 56 | +have designed this version of the GPL to prohibit the practice for those |
| 57 | +products. If such problems arise substantially in other domains, we |
| 58 | +stand ready to extend this provision to those domains in future versions |
| 59 | +of the GPL, as needed to protect the freedom of users. |
| 60 | + |
| 61 | + Finally, every program is threatened constantly by software patents. |
| 62 | +States should not allow patents to restrict development and use of |
| 63 | +software on general-purpose computers, but in those that do, we wish to |
| 64 | +avoid the special danger that patents applied to a free program could |
| 65 | +make it effectively proprietary. To prevent this, the GPL assures that |
| 66 | +patents cannot be used to render the program non-free. |
| 67 | + |
| 68 | + The precise terms and conditions for copying, distribution and |
| 69 | +modification follow. |
| 70 | + |
| 71 | + TERMS AND CONDITIONS |
| 72 | + |
| 73 | + 0. Definitions. |
| 74 | + |
| 75 | + "This License" refers to version 3 of the GNU General Public License. |
| 76 | + |
| 77 | + "Copyright" also means copyright-like laws that apply to other kinds of |
| 78 | +works, such as semiconductor masks. |
| 79 | + |
| 80 | + "The Program" refers to any copyrightable work licensed under this |
| 81 | +License. Each licensee is addressed as "you". "Licensees" and |
| 82 | +"recipients" may be individuals or organizations. |
| 83 | + |
| 84 | + To "modify" a work means to copy from or adapt all or part of the work |
| 85 | +in a fashion requiring copyright permission, other than the making of an |
| 86 | +exact copy. The resulting work is called a "modified version" of the |
| 87 | +earlier work or a work "based on" the earlier work. |
| 88 | + |
| 89 | + A "covered work" means either the unmodified Program or a work based |
| 90 | +on the Program. |
| 91 | + |
| 92 | + To "propagate" a work means to do anything with it that, without |
| 93 | +permission, would make you directly or secondarily liable for |
| 94 | +infringement under applicable copyright law, except executing it on a |
| 95 | +computer or modifying a private copy. Propagation includes copying, |
| 96 | +distribution (with or without modification), making available to the |
| 97 | +public, and in some countries other activities as well. |
| 98 | + |
| 99 | + To "convey" a work means any kind of propagation that enables other |
| 100 | +parties to make or receive copies. Mere interaction with a user through |
| 101 | +a computer network, with no transfer of a copy, is not conveying. |
| 102 | + |
| 103 | + An interactive user interface displays "Appropriate Legal Notices" |
| 104 | +to the extent that it includes a convenient and prominently visible |
| 105 | +feature that (1) displays an appropriate copyright notice, and (2) |
| 106 | +tells the user that there is no warranty for the work (except to the |
| 107 | +extent that warranties are provided), that licensees may convey the |
| 108 | +work under this License, and how to view a copy of this License. If |
| 109 | +the interface presents a list of user commands or options, such as a |
| 110 | +menu, a prominent item in the list meets this criterion. |
| 111 | + |
| 112 | + 1. Source Code. |
| 113 | + |
| 114 | + The "source code" for a work means the preferred form of the work |
| 115 | +for making modifications to it. "Object code" means any non-source |
| 116 | +form of a work. |
| 117 | + |
| 118 | + A "Standard Interface" means an interface that either is an official |
| 119 | +standard defined by a recognized standards body, or, in the case of |
| 120 | +interfaces specified for a particular programming language, one that |
| 121 | +is widely used among developers working in that language. |
| 122 | + |
| 123 | + The "System Libraries" of an executable work include anything, other |
| 124 | +than the work as a whole, that (a) is included in the normal form of |
| 125 | +packaging a Major Component, but which is not part of that Major |
| 126 | +Component, and (b) serves only to enable use of the work with that |
| 127 | +Major "Major Component", in this context, means a major essential component |
| 128 | +(kernel, window system, and so on) of the specific operating system |
| 129 | +(if any) on which the executable work r, it does not include the work's |
| 130 | +System Libraries, or general-purpose tools or generally available free |
| 131 | +programs which are used unmodified in performing those activities but |
| 132 | +which are not part of the work. For eose |
| 133 | +subprograms and other parts of the work. |
| 134 | + |
| 135 | + The Corresponding Source need not include anything that users |
| 136 | +can regenerate automatically from other parts of the work. |
| 137 | + |
| 138 | + 2. Basic Permissions. |
| 139 | + |
| 140 | + All rights gran unmodified Program. The output from running a |
| 141 | +covered work is covered by this |
| 142 | + |
| 143 | + You may make, run and propagate covered works that you do not |
| 144 | +convey, without conditions so long as your license otherwise remainyou, or proively on your behalf, under your direction |
| 145 | +and control, on terms that prohibit them from making any copies of |
| 146 | +your copyrighted material outside their relationship with you. |
| 147 | + |
| 148 | + Conveying under any otherg obligations under article |
| 149 | +11 of the WIPO copyright treaty adopted on 20 December 1996, or |
| 150 | +similar laws prohibiting or restricting circumvention of such |
| 151 | +measures. |
| 152 | + |
| 153 | + When you convey a covered work, you waive any k's |
| 154 | +users, your or third parties' legal rights to forbidsly and |
| 155 | +appropriately publish on each copy an appropriate copyright notice; |
| 156 | +keep intact all notices stating that this License and any |
| 157 | +non-permissive terms amay convey a work based on the Program, or the modifications to |
| 158 | +produce it from the Program, in the form of source code under the |
| 159 | +terms of section 4, provided that you also meet all of these conditions: |
| 160 | + |
| 161 | + a) T |
| 162 | + "keep intact all notices". |
| 163 | + |
| 164 | + c) You must license the entire work, as a whole, under this |
| 165 | + License to anyone who comes into possession of a copy. This |
| 166 | + License will therefore apply, along with any ae work has interactive user interfaces, each must display |
| 167 | + Appropriate Legal Notices; however, if the Program has interactive |
| 168 | + interfaces that do not display Apered work with other separate and independent |
| 169 | +regate" if the compilation and its resulting copyright are not |
| 170 | +used to limit the access or legal rights of the c the other |
| 171 | +parts of the aggregate. |
| 172 | + |
| 173 | + 6. Conveying Non-Source Forms. |
| 174 | + |
| 175 | + You may convey a covered woricensware interchange. |
| 176 | + |
| 177 | + b) Convey the object code in, or embodied in, a physical product |
| 178 | + (including a physical distribution medium), accompanied by a |
| 179 | + written offer, valid for at least three years and ly used for software interchange, for a price no |
| 180 | + more than your reasonable cost of physically performing this |
| 181 | + conveying of source, or (2) access to copy the |
| 182 | + Correes of the object code with a copy of tection 6b. |
| 183 | + |
| 184 | + d) Convey the object code by offering access from a designated |
| 185 | + place (gratis or for a charge),quire recipients to copy the |
| 186 | + Corresponding Source along with the object code. If the place toequival available for as long as needed to satisfy these requirements. |
| 187 | + |
| 188 | + e) Convey the object code using peer-to-peer transmission, provided |
| 189 | + you inform other peers where the object code and Corresponding |
| 190 | +her (1) a "consumer product", which means any |
| 191 | +tangible personal property which is normally used for personal, family, |
| 192 | +or household purposes, or (2) anything designed or sold for incorporation |
| 193 | +into a dwelling. Inway in which the particular user |
| 194 | +ly significant mode of use of the product. |
| 195 | + |
| 196 | + "Installation Information" for a User Product means any methods, |
| 197 | +procedures, authorization keys, or other information required to insbject code work under this section in, or with, or |
| 198 | +specifically for use in, a User Product, and the conveying occurs as |
| 199 | +part of a transaction in which the right of possession and use of the |
| 200 | +User Product is transf ability to install |
| 201 | +modified object code on the User Product (for example, the work has |
| 202 | +been installed in ROM). |
| 203 | + |
| 204 | + The requirement to provide Installation Information does not include a |
| 205 | +requirement to continue totwork or violates the rules and |
| 206 | +protocols for communica available to the public in |
| 207 | +source code form), and must require no special password or key for |
| 208 | +unpacking, reading or copying. |
| 209 | + |
| 210 | + 7. Additional Terms. |
| 211 | + |
| 212 | + "Addpart of the Program, that part may be used separately |
| 213 | +under those permissions, but the entire Program remains governed by |
| 214 | +this License without regard to the additional permissions. |
| 215 | + |
| 216 | + When you convey a copy of a work, |
| 217 | +for which you have or can give appropriate copyright permission. |
| 218 | + |
| 219 | + Notwithstanding any other provision of this License, for material you |
| 220 | +add to a covered work, you may (if authorized by the copyright f thaterial or in the Apt from the original version; or |
| 221 | + |
| 222 | + d) Limiting the use for publicity purposes of names of licensors or |
| 223 | + authors of the material; or |
| 224 | + |
| 225 | + e) Declining to grant rights under trademark law fsumptions directly impose on |
| 226 | + those licensors and authors. |
| 227 | + |
| 228 | + All other non-permissive additional terms are considered "further |
| 229 | +restrictions" within the meaning of section 10. If the Program as you |
| 230 | +received itmaterial governed by the terms |
| 231 | +of that license document, provided that the further restriction does |
| 232 | +not survive such relicensing or conveying. |
| 233 | + |
| 234 | + If you add terms to a covered work in accord with this section, yo |
| 235 | +the above requirements apply either way. |
| 236 | + |
| 237 | + 8. Termination. |
| 238 | + |
| 239 | + You may not propagate or rights under |
| 240 | +this License (including any patent licenses granted under the third |
| 241 | +paragraph of section 11). |
| 242 | + |
| 243 | + However, if y particular copyright holder is |
| 244 | +reinstated permanently if the copyright holder notifies you of the |
| 245 | +violation by some reasonable means, this is the first time you have |
| 246 | +received notice of violation of this License en terminated and not permanently |
| 247 | +reinstated, you do not qualify to receive new licenses for the same |
| 248 | +material under section 10. |
| 249 | + |
| 250 | + 9. Acceptance Not Required for Having Copies. |
| 251 | + |
| 252 | + You are not required to accepy agate or |
| 253 | +modify any covered work. These actions infringe copyright if you do |
| 254 | +not accept this License. Therefore, by ecipients. |
| 255 | + |
| 256 | + Each time you convey a covered work, the recipient automatically |
| 257 | +receives a licey transaction, each party to that |
| 258 | +transaction who receives a copy of the work also receives whatever |
| 259 | +licenses to the work the party's predecessor in interest had or could |
| 260 | +give under the previous paragraph, plus a ot impose a license fee, royalty, or other charge for exercise of |
| 261 | +rights granted under this License, and you may not initiate litigation |
| 262 | +(including a cross-claim or counterclaim in a lawsuit) allling, offering fd the contributor's "contributor version". |
| 263 | + |
| 264 | + A contributor's "essential patent claims" are all patent claims |
| 265 | +owned oLicense, of making, using, or selling its contributor version, |
| 266 | +but do not include claims that wimport and otherwise run, modify and |
| 267 | +propagate the contents of its contributor version. |
| 268 | + |
| 269 | + In the following three paragraphs, a "patent license" is any express |
| 270 | +agreement or commitment, however denominated, not toing on a patent license, |
| 271 | +and the Corresponding Source of the work is not available for anyone |
| 272 | +to copy, free of charge and under the terms of this1) cause the Corresponding Source to be so |
| 273 | +available, or (2) arrangse to downstream recipients. "Knowingly relying" means you have |
| 274 | +actual kble patents in that |
| 275 | +country that you have reason to believe are valid. |
| 276 | + |
| 277 | + If, pursuant to or in connection with a single transaction or |
| 278 | +arratent license is "discriminatory" if it does not include within |
| 279 | +the scope of its coverage, prohibits the exercise of, or is |
| 280 | +conditioned on the non-exercise of one or more of the rights that are |
| 281 | +specifically grantrty grants, to any of the |
| 282 | +parties who would receive the covered work from you, a discriminatory |
| 283 | +patent license (a) in connection with copies of the c specific products or compilations that |
| 284 | +contain the covered workse orions of this License, they do not |
| 285 | +excuse you from the conditions of this License. If you cannot convey a |
| 286 | +covered work so as to satisfy simultaneously your obligations under this |
| 287 | +License and any other pertinom conveying the Program. |
| 288 | + |
| 289 | + 13. Use with the GNU Affero General Public License. |
| 290 | + |
| 291 | + Notwithstanding any other provision of this License, you have |
| 292 | +permission to link or combine any covered work with a work licensening interaction through a network will apply to the |
| 293 | +combination as such. |
| 294 | + |
| 295 | + 14. Revised Versions of this License. |
| 296 | + |
| 297 | + The Free Software Foundation may pubns will |
| 298 | +be similar in spirit to the present version, but m License "or any later version" ap the |
| 299 | +GNU General Public License, you may choose any version ever published |
| 300 | +by the Free Software Foundation. |
| 301 | + |
| 302 | + If the Program specifies that a proxy can decide which future |
| 303 | +versis a result of your choosing to follow a |
| 304 | +later version. |
| 305 | + |
| 306 | + 15. Disclaimer of Warranty. |
| 307 | + |
| 308 | + THERE IS NO WARRANTY FOR THE PROGRAM, TO THE EXTENT PERMITTED BY |
| 309 | +APPLICABLE LAW. EXCEPT WHEN OTHERWISE STATED IN WRITING TOGRAM |
| 310 | +IS WITH YOU. SHOULD THE PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF |
| 311 | +ALL NECESSARY SERVICING, REPAIR OR CORRECTION. |
| 312 | + |
| 313 | + 16. Limitation of Liability. |
| 314 | + |
| 315 | + IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGITED TO LOSS OF |
| 316 | +DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD |
| 317 | +PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER PROGRAMS), |
| 318 | +EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN A7. ute waiver of all civil liability in connection with the |
| 319 | +Program, unless a warranty or assumption of liability accompanies a |
| 320 | +copy of the Program in return for a Your New Programs |
