By contrast, 15*ff0253f9SPatrick Williamsthe GNU General Public License is intended to guarantee your freedom to 16*ff0253f9SPatrick Williamsshare and change all versions of a program--to make sure it remains free 17*ff0253f9SPatrick Williamssoftware for all its users. We, the Free Software Foundation, use the 18*ff0253f9SPatrick WilliamsGNU General Public License for most of our software; it applies also to 19*ff0253f9SPatrick Williamsany other work released this way by its authors. You can apply it to 20*ff0253f9SPatrick Williamsyour programs, too. 21*ff0253f9SPatrick Williams 22*ff0253f9SPatrick Williams When we speak of free software, we are referring to freedom, not 23*ff0253f9SPatrick Williamsprice. Our General Public Licenses are designed to make sure that you 24*ff0253f9SPatrick Williamshave the freedom to distribute copies of free software (and charge for 25*ff0253f9SPatrick Williamsthem if you wish), that you receive source code or can get it if you 26*ff0253f9SPatrick Williamswant it, that you can change the software or use pieces of it in new 27*ff0253f9SPatrick Williamsfree programs, and that you know you can do these things. 28*ff0253f9SPatrick Williams 29*ff0253f9SPatrick Williams To protect your rights, we need to prevent others from denying you 30*ff0253f9SPatrick Williamsthese rights or asking you to surrender the rights. Therefore, you have 31*ff0253f9SPatrick Williamscertain responsibilities if you distribute copies of the software, or if 32*ff0253f9SPatrick Williamsyou modify it: responsibilities to respect the freedom of others. 33*ff0253f9SPatrick Williams 34*ff0253f9SPatrick Williams For example, if you distribute copies of such a program, whether 35*ff0253f9SPatrick Williamsgratis or for a fee, you must pass on to the recipients the same 36*ff0253f9SPatrick Williamsfreedoms that you received. You must make sure that they, too, receive 37*ff0253f9SPatrick Williamsor can get the source code. And you must show them these terms so they 38*ff0253f9SPatrick Williamsknow their rights. 39*ff0253f9SPatrick Williams 40*ff0253f9SPatrick Williams Developers that use the GNU GPL protect your rights with two steps: 41*ff0253f9SPatrick Williams(1) assert copyright on the software, and (2) offer you this License 42*ff0253f9SPatrick Williamsgiving you legal permission to copy, distribute and/or modify it. 43*ff0253f9SPatrick Williams 44*ff0253f9SPatrick Williams For the developers' and authors' protection, the GPL clearly explains 45*ff0253f9SPatrick Williamsthat there is no warranty for this free software. For both users' and 46*ff0253f9SPatrick Williamsauthors' sake, the GPL requires that modified versions be marked as 47*ff0253f9SPatrick Williamschanged, so that their problems will not be attributed erroneously to 48*ff0253f9SPatrick Williamsauthors of previous versions. 49*ff0253f9SPatrick Williams 50*ff0253f9SPatrick Williams Some devices are designed to deny users access to install or run 51*ff0253f9SPatrick Williamsmodified versions of the software inside them, although the manufacturer 52*ff0253f9SPatrick Williamscan do so. This is fundamentally incompatible with the aim of 53*ff0253f9SPatrick Williamsprotecting users' freedom to change the software. The systematic 54*ff0253f9SPatrick Williamspattern of such abuse occurs in the area of products for individuals to 55*ff0253f9SPatrick Williamsuse, which is precisely where it is most unacceptable. Therefore, we 56*ff0253f9SPatrick Williamshave designed this version of the GPL to prohibit the practice for those 57*ff0253f9SPatrick Williamsproducts. If such problems arise substantially in other domains, we 58*ff0253f9SPatrick Williamsstand ready to extend this provision to those domains in future versions 59*ff0253f9SPatrick Williamsof the GPL, as needed to protect the freedom of users. 60*ff0253f9SPatrick Williams 61*ff0253f9SPatrick Williams Finally, every program is threatened constantly by software patents. 62*ff0253f9SPatrick WilliamsStates should not allow patents to restrict development and use of 63*ff0253f9SPatrick Williamssoftware on general-purpose computers, but in those that do, we wish to 64*ff0253f9SPatrick Williamsavoid the special danger that patents applied to a free program could 65*ff0253f9SPatrick Williamsmake it effectively proprietary. To prevent this, the GPL assures that 66*ff0253f9SPatrick Williamspatents cannot be used to render the program non-free. 67*ff0253f9SPatrick Williams 68*ff0253f9SPatrick Williams The precise terms and conditions for copying, distribution and 69*ff0253f9SPatrick Williamsmodification follow. 70*ff0253f9SPatrick Williams 71*ff0253f9SPatrick Williams TERMS AND CONDITIONS 72*ff0253f9SPatrick Williams 73*ff0253f9SPatrick Williams 0. Definitions. 74*ff0253f9SPatrick Williams 75*ff0253f9SPatrick Williams "This License" refers to version 3 of the GNU General Public License. 76*ff0253f9SPatrick Williams 77*ff0253f9SPatrick Williams "Copyright" also means copyright-like laws that apply to other kinds of 78*ff0253f9SPatrick Williamsworks, such as semiconductor masks. 79*ff0253f9SPatrick Williams 80*ff0253f9SPatrick Williams "The Program" refers to any copyrightable work licensed under this 81*ff0253f9SPatrick WilliamsLicense. Each licensee is addressed as "you". "Licensees" and 82*ff0253f9SPatrick Williams"recipients" may be individuals or organizations. 83*ff0253f9SPatrick Williams 84*ff0253f9SPatrick Williams To "modify" a work means to copy from or adapt all or part of the work 85*ff0253f9SPatrick Williamsin a fashion requiring copyright permission, other than the making of an 86*ff0253f9SPatrick Williamsexact copy. The resulting work is called a "modified version" of the 87*ff0253f9SPatrick Williamsearlier work or a work "based on" the earlier work. 88*ff0253f9SPatrick Williams 89*ff0253f9SPatrick Williams A "covered work" means either the unmodified Program or a work based 90*ff0253f9SPatrick Williamson the Program. 91*ff0253f9SPatrick Williams 92*ff0253f9SPatrick Williams To "propagate" a work means to do anything with it that, without 93*ff0253f9SPatrick Williamspermission, would make you directly or secondarily liable for 94*ff0253f9SPatrick Williamsinfringement under applicable copyright law, except executing it on a 95*ff0253f9SPatrick Williamscomputer or modifying a private copy. Propagation includes copying, 96*ff0253f9SPatrick Williamsdistribution (with or without modification), making available to the 97*ff0253f9SPatrick Williamspublic, and in some countries other activities as well. 98*ff0253f9SPatrick Williams 99*ff0253f9SPatrick Williams To "convey" a work means any kind of propagation that enables other 100*ff0253f9SPatrick Williamsparties to make or receive copies. Mere interaction with a user through 101*ff0253f9SPatrick Williamsa computer network, with no transfer of a copy, is not conveying. 102*ff0253f9SPatrick Williams 103*ff0253f9SPatrick Williams An interactive user interface displays "Appropriate Legal Notices" 104*ff0253f9SPatrick Williamsto the extent that it includes a convenient and prominently visible 105*ff0253f9SPatrick Williamsfeature that (1) displays an appropriate copyright notice, and (2) 106*ff0253f9SPatrick Williamstells the user that there is no warranty for the work (except to the 107*ff0253f9SPatrick Williamsextent that warranties are provided), that licensees may convey the 108*ff0253f9SPatrick Williamswork under this License, and how to view a copy of this License. If 109*ff0253f9SPatrick Williamsthe interface presents a list of user commands or options, such as a 110*ff0253f9SPatrick Williamsmenu, a prominent item in the list meets this criterion. 111*ff0253f9SPatrick Williams 112*ff0253f9SPatrick Williams 1. Source Code. 113*ff0253f9SPatrick Williams 114*ff0253f9SPatrick Williams The "source code" for a work means the preferred form of the work 115*ff0253f9SPatrick Williamsfor making modifications to it. "Object code" means any non-source 116*ff0253f9SPatrick Williamsform of a work. 117*ff0253f9SPatrick Williams 118*ff0253f9SPatrick Williams A "Standard Interface" means an interface that either is an official 119*ff0253f9SPatrick Williamsstandard defined by a recognized standards body, or, in the case of 120*ff0253f9SPatrick Williamsinterfaces specified for a particular programming language, one that 121*ff0253f9SPatrick Williamsis widely used among developers working in that language. 122*ff0253f9SPatrick Williams 123*ff0253f9SPatrick Williams The "System Libraries" of an executable work include anything, other 124*ff0253f9SPatrick Williamsthan the work as a whole, that (a) is included in the normal form of 125*ff0253f9SPatrick Williamspackaging a Major Component, but which is not part of that Major 126*ff0253f9SPatrick WilliamsComponent, and (b) serves only to enable use of the work with that 127*ff0253f9SPatrick WilliamsMajor Component, or to implement a Standard Interface for which an 128*ff0253f9SPatrick Williamsimplementation is available to the public in source code form. A 129*ff0253f9SPatrick Williams"Major Component", in this context, means a major essential component 130*ff0253f9SPatrick Williams(kernel, window system, and so on) of the specific operating system 131*ff0253f9SPatrick Williams(if any) on which the executable work runs, or a compiler used to 132*ff0253f9SPatrick Williamsproduce the work, or an object code interpreter used to run it. 133*ff0253f9SPatrick Williams 134*ff0253f9SPatrick Williams The "Corresponding Source" for a work in object code form means all 135*ff0253f9SPatrick Williamsthe source code needed to generate, install, and (for an executable 136*ff0253f9SPatrick Williamswork) run the object code and to modify the work, including scripts to 137*ff0253f9SPatrick Williamscontrol those activities. However, it does not include the work's 138*ff0253f9SPatrick WilliamsSystem Libraries, or general-purpose tools or generally available free 139*ff0253f9SPatrick Williamsprograms which are used unmodified in performing those activities but 140*ff0253f9SPatrick Williamswhich are not part of the work. For example, Corresponding Source 141*ff0253f9SPatrick Williamsincludes interface definition files associated with source files for 142*ff0253f9SPatrick Williamsthe work, and the source code for shared libraries and dynamically 143*ff0253f9SPatrick Williamslinked subprograms that the work is specifically designed to require, 144*ff0253f9SPatrick Williamssuch as by intimate data communication or control flow between those 145*ff0253f9SPatrick Williamssubprograms and other parts of the work. 146*ff0253f9SPatrick Williams 147*ff0253f9SPatrick Williams The Corresponding Source need not include anything that users 148*ff0253f9SPatrick Williamscan regenerate automatically from other parts of the Corresponding 149*ff0253f9SPatrick WilliamsSource. 150*ff0253f9SPatrick Williams 151*ff0253f9SPatrick Williams The Corresponding Source for a work in source code form is that 152*ff0253f9SPatrick Williamssame work. 153*ff0253f9SPatrick Williams 154*ff0253f9SPatrick Williams 2. Basic Permissions. 155*ff0253f9SPatrick Williams 156*ff0253f9SPatrick Williams All rights granted under this License are granted for the term of 157*ff0253f9SPatrick Williamscopyright on the Program, and are irrevocable provided the stated 158*ff0253f9SPatrick Williamsconditions are met. This License explicitly affirms your unlimited 159*ff0253f9SPatrick Williamspermission to run the unmodified Program. The output from running a 160*ff0253f9SPatrick Williamscovered work is covered by this License only if the output, given its 161*ff0253f9SPatrick Williamscontent, constitutes a covered work. This License acknowledges your 162*ff0253f9SPatrick Williamsrights of fair use or other equivalent, as provided by copyright law. 163*ff0253f9SPatrick Williams 164*ff0253f9SPatrick Williams You may make, run and propagate covered works that you do not 165*ff0253f9SPatrick Williamsconvey, without conditions so long as your license otherwise remains 166*ff0253f9SPatrick Williamsin force. You may convey covered works to others for the sole purpose 167*ff0253f9SPatrick Williamsof having them make modifications exclusively for you, or provide you 168*ff0253f9SPatrick Williamswith facilities for running those works, provided that you comply with 169*ff0253f9SPatrick Williamsthe terms of this License in conveying all material for which you do 170*ff0253f9SPatrick Williamsnot control copyright. Those thus making or running the covered works 171*ff0253f9SPatrick Williamsfor you must do so exclusively on your behalf, under your direction 172*ff0253f9SPatrick Williamsand control, on terms that prohibit them from making any copies of 173*ff0253f9SPatrick Williamsyour copyrighted material outside their relationship with you. 174*ff0253f9SPatrick Williams 175*ff0253f9SPatrick Williams Conveying under any other circumstances is permitted solely under 176*ff0253f9SPatrick Williamsthe conditions stated below. Sublicensing is not allowed; section 10 177*ff0253f9SPatrick Williamsmakes it unnecessary. 178*ff0253f9SPatrick Williams 179*ff0253f9SPatrick Williams 3. Protecting Users' Legal Rights From Anti-Circumvention Law. 180*ff0253f9SPatrick Williams 181*ff0253f9SPatrick Williams No covered work shall be deemed part of an effective technological 182*ff0253f9SPatrick Williamsmeasure under any applicable law fulfilling obligations under article 183*ff0253f9SPatrick Williams11 of the WIPO copyright treaty adopted on 20 December 1996, or 184*ff0253f9SPatrick Williamssimilar laws prohibiting or restricting circumvention of such 185*ff0253f9SPatrick Williamsmeasures. 186*ff0253f9SPatrick Williams 187*ff0253f9SPatrick Williams When you convey a covered work, you waive any legal power to forbid 188*ff0253f9SPatrick Williamscircumvention of technological measures to the extent such circumvention 189*ff0253f9SPatrick Williamsis effected by exercising rights under this License with respect to 190*ff0253f9SPatrick Williamsthe covered work, and you disclaim any intention to limit operation or 191*ff0253f9SPatrick Williamsmodification of the work as a means of enforcing, against the work's 192*ff0253f9SPatrick Williamsusers, your or third parties' legal rights to forbid circumvention of 193*ff0253f9SPatrick Williamstechnological measures. 194*ff0253f9SPatrick Williams 195*ff0253f9SPatrick Williams 4. Conveying Verbatim Copies. 196*ff0253f9SPatrick Williams 197*ff0253f9SPatrick Williams You may convey verbatim copies of the Program's source code as you 198*ff0253f9SPatrick Williamsreceive it, in any medium, provided that you conspicuously and 199*ff0253f9SPatrick Williamsappropriately publish on each copy an appropriate copyright notice; 200*ff0253f9SPatrick Williamskeep intact all notices stating that this License and any 201*ff0253f9SPatrick Williamsnon-permissive terms added in accord with section 7 apply to the code; 202*ff0253f9SPatrick Williamskeep intact all notices of the absence of any warranty; and give all 203*ff0253f9SPatrick Williamsrecipients a copy of this License along with the Program. 204*ff0253f9SPatrick Williams 205*ff0253f9SPatrick Williams You may charge any price or no price for each copy that you convey, 206*ff0253f9SPatrick Williamsand you may offer support or warranty protection for a fee. 207*ff0253f9SPatrick Williams 208*ff0253f9SPatrick Williams 5. Conveying Modified Source Versions. 209*ff0253f9SPatrick Williams 210*ff0253f9SPatrick Williams You may convey a work based on the Program, or the modifications to 211*ff0253f9SPatrick Williamsproduce it from the Program, in the form of source code under the 212*ff0253f9SPatrick Williamsterms of section 4, provided that you also meet all of these conditions: 213*ff0253f9SPatrick Williams 214*ff0253f9SPatrick Williams a) The work must carry prominent notices stating that you modified 215*ff0253f9SPatrick Williams it, and giving a relevant date. 216*ff0253f9SPatrick Williams 217*ff0253f9SPatrick Williams b) The work must carry prominent notices stating that it is 218*ff0253f9SPatrick Williams released under this License and any conditions added under section 219*ff0253f9SPatrick Williams 7. This requirement modifies the requirement in section 4 to 220*ff0253f9SPatrick Williams "keep intact all notices". 221*ff0253f9SPatrick Williams 222*ff0253f9SPatrick Williams c) You must license the entire work, as a whole, under this 223*ff0253f9SPatrick Williams License to anyone who comes into possession of a copy. This 224*ff0253f9SPatrick Williams License will therefore apply, along with any applicable section 7 225*ff0253f9SPatrick Williams additional terms, to the whole of the work, and all its parts, 226*ff0253f9SPatrick Williams regardless of how they are packaged. This License gives no 227*ff0253f9SPatrick Williams permission to license the work in any other way, but it does not 228*ff0253f9SPatrick Williams invalidate such permission if you have separately received it. 229*ff0253f9SPatrick Williams 230*ff0253f9SPatrick Williams d) If the work has interactive user interfaces, each must display 231*ff0253f9SPatrick Williams Appropriate Legal Notices; however, if the Program has interactive 232*ff0253f9SPatrick Williams interfaces that do not display Appropriate Legal Notices, your 233*ff0253f9SPatrick Williams work need not make them do so. 234*ff0253f9SPatrick Williams 235*ff0253f9SPatrick Williams A compilation of a covered work with other separate and independent 236*ff0253f9SPatrick Williamsworks, which are not by their nature extensions of the covered work, 237*ff0253f9SPatrick Williamsand which are not combined with it such as to form a larger program, 238*ff0253f9SPatrick Williamsin or on a volume of a storage or distribution medium, is called an 239*ff0253f9SPatrick Williams"aggregate" if the compilation and its resulting copyright are not 240*ff0253f9SPatrick Williamsused to limit the access or legal rights of the compilation's users 241*ff0253f9SPatrick Williamsbeyond what the individual works permit. Inclusion of a covered work 242*ff0253f9SPatrick Williamsin an aggregate does not cause this License to apply to the other 243*ff0253f9SPatrick Williamsparts of the aggregate. 244*ff0253f9SPatrick Williams 245*ff0253f9SPatrick Williams 6. Conveying Non-Source Forms. 246*ff0253f9SPatrick Williams 247*ff0253f9SPatrick Williams You may convey a covered work in object code form under the terms 248*ff0253f9SPatrick Williamsof sections 4 and 5, provided that you also convey the 249*ff0253f9SPatrick Williamsmachine-readable Corresponding Source under the terms of this License, 250*ff0253f9SPatrick Williamsin one of these ways: 251*ff0253f9SPatrick Williams 252*ff0253f9SPatrick Williams a) Convey the object code in, or embodied in, a physical product 253*ff0253f9SPatrick Williams (including a physical distribution medium), accompanied by the 254*ff0253f9SPatrick Williams Corresponding Source fixed on a durable physical medium 255*ff0253f9SPatrick Williams customarily used for software interchange. 256*ff0253f9SPatrick Williams 257*ff0253f9SPatrick Williams b) Convey the object code in, or embodied in, a physical product 258*ff0253f9SPatrick Williams (including a physical distribution medium), accompanied by a 259*ff0253f9SPatrick Williams written offer, valid for at least three years and valid for as 260*ff0253f9SPatrick Williams long as you offer spare parts or customer support for that product 261*ff0253f9SPatrick Williams model, to give anyone who possesses the object code either (1) a 262*ff0253f9SPatrick Williams copy of the Corresponding Source for all the software in the 263*ff0253f9SPatrick Williams product that is covered by this License, on a durable physical 264*ff0253f9SPatrick Williams medium customarily used for software interchange, for a price no 265*ff0253f9SPatrick Williams more than your reasonable cost of physically performing this 266*ff0253f9SPatrick Williams conveying of source, or (2) access to copy the 267*ff0253f9SPatrick Williams Corresponding Source from a network server at no charge. 268*ff0253f9SPatrick Williams 269*ff0253f9SPatrick Williams c) Convey individual copies of the object code with a copy of the 270*ff0253f9SPatrick Williams written offer to provide the Corresponding Source. This 271*ff0253f9SPatrick Williams alternative is allowed only occasionally and noncommercially, and 272*ff0253f9SPatrick Williams only if you received the object code with such an offer, in accord 273*ff0253f9SPatrick Williams with subsection 6b. 274*ff0253f9SPatrick Williams 275*ff0253f9SPatrick Williams d) Convey the object code by offering access from a designated 276*ff0253f9SPatrick Williams place (gratis or for a charge), and offer equivalent access to the 277*ff0253f9SPatrick Williams Corresponding Source in the same way through the same place at no 278*ff0253f9SPatrick Williams further charge. You need not require recipients to copy the 279*ff0253f9SPatrick Williams Corresponding Source along with the object code. If the place to 280*ff0253f9SPatrick Williams copy the object code is a network server, the Corresponding Source 281*ff0253f9SPatrick Williams may be on a different server (operated by you or a third party) 282*ff0253f9SPatrick Williams that supports equivalent copying facilities, provided you maintain 283*ff0253f9SPatrick Williams clear directions next to the object code saying where to find the 284*ff0253f9SPatrick Williams Corresponding Source. Regardless of what server hosts the 285*ff0253f9SPatrick Williams Corresponding Source, you remain obligated to ensure that it is 286*ff0253f9SPatrick Williams available for as long as needed to satisfy these requirements. 287*ff0253f9SPatrick Williams 288*ff0253f9SPatrick Williams e) Convey the object code using peer-to-peer transmission, provided 289*ff0253f9SPatrick Williams you inform other peers where the object code and Corresponding 290*ff0253f9SPatrick Williams Source of the work are being offered to the general public at no 291*ff0253f9SPatrick Williams charge under subsection 6d. 292*ff0253f9SPatrick Williams 293*ff0253f9SPatrick Williams A separable portion of the object code, whose source code is excluded 294*ff0253f9SPatrick Williamsfrom the Corresponding Source as a System Library, need not be 295*ff0253f9SPatrick Williamsincluded in conveying the object code work. 296*ff0253f9SPatrick Williams 297*ff0253f9SPatrick Williams A "User Product" is either (1) a "consumer product", which means any 298*ff0253f9SPatrick Williamstangible personal property which is normally used for personal, family, 299*ff0253f9SPatrick Williamsor household purposes, or (2) anything designed or sold for incorporation 300*ff0253f9SPatrick Williamsinto a dwelling. In determining whether a product is a consumer product, 301*ff0253f9SPatrick Williamsdoubtful cases shall be resolved in favor of coverage. For a particular 302*ff0253f9SPatrick Williamsproduct received by a particular user, "normally used" refers to a 303*ff0253f9SPatrick Williamstypical or common use of that class of product, regardless of the status 304*ff0253f9SPatrick Williamsof the particular user or of the way in which the particular user 305*ff0253f9SPatrick Williamsactually uses, or expects or is expected to use, the product. A product 306*ff0253f9SPatrick Williamsis a consumer product regardless of whether the product has substantial 307*ff0253f9SPatrick Williamscommercial, industrial or non-consumer uses, unless such uses represent 308*ff0253f9SPatrick Williamsthe only significant mode of use of the product. 309*ff0253f9SPatrick Williams 310*ff0253f9SPatrick Williams "Installation Information" for a User Product means any methods, 311*ff0253f9SPatrick Williamsprocedures, authorization keys, or other information required to install 312*ff0253f9SPatrick Williamsand execute modified versions of a covered work in that User Product from 313*ff0253f9SPatrick Williamsa modified version of its Corresponding Source. The information must 314*ff0253f9SPatrick Williamssuffice to ensure that the continued functioning of the modified object 315*ff0253f9SPatrick Williamscode is in no case prevented or interfered with solely because 316*ff0253f9SPatrick Williamsmodification has been made. 317*ff0253f9SPatrick Williams 318*ff0253f9SPatrick Williams If you convey an object code work under this section in, or with, or 319*ff0253f9SPatrick Williamsspecifically for use in, a User Product, and the conveying occurs as 320*ff0253f9SPatrick Williamspart of a transaction in which the right of possession and use of the 321*ff0253f9SPatrick WilliamsUser Product is transferred to the recipient in perpetuity or for a 322*ff0253f9SPatrick Williamsfixed term (regardless of how the transaction is characterized), the 323*ff0253f9SPatrick WilliamsCorresponding Source conveyed under this section must be accompanied 324*ff0253f9SPatrick Williamsby the Installation Information. But this requirement does not apply 325*ff0253f9SPatrick Williamsif neither you nor any third party retains the ability to install 326*ff0253f9SPatrick Williamsmodified object code on the User Product (for example, the work has 327*ff0253f9SPatrick Williamsbeen installed in ROM). 328*ff0253f9SPatrick Williams 329*ff0253f9SPatrick Williams The requirement to provide Installation Information does not include a 330*ff0253f9SPatrick Williamsrequirement to continue to provide support service, warranty, or updates 331*ff0253f9SPatrick Williamsfor a work that has been modified or installed by the recipient, or for 332*ff0253f9SPatrick Williamsthe User Product in which it has been modified or installed. Access to a 333*ff0253f9SPatrick Williamsnetwork may be denied when the modification itself materially and 334*ff0253f9SPatrick Williamsadversely affects the operation of the network or violates the rules and 335*ff0253f9SPatrick Williamsprotocols for communication across the network. 336*ff0253f9SPatrick Williams 337*ff0253f9SPatrick Williams Corresponding Source conveyed, and Installation Information provided, 338*ff0253f9SPatrick Williamsin accord with this section must be in a format that is publicly 339*ff0253f9SPatrick Williamsdocumented (and with an implementation available to the public in 340*ff0253f9SPatrick Williamssource code form), and must require no special password or key for 341*ff0253f9SPatrick Williamsunpacking, reading or copying. 342*ff0253f9SPatrick Williams 343*ff0253f9SPatrick Williams 7. Additional Terms. 344*ff0253f9SPatrick Williams 345*ff0253f9SPatrick Williams "Additional permissions" are terms that supplement the terms of this 346*ff0253f9SPatrick WilliamsLicense by making exceptions from one or more of its conditions. 347*ff0253f9SPatrick WilliamsAdditional permissions that are applicable to the entire Program shall 348*ff0253f9SPatrick Williamsbe treated as though they were included in this License, to the extent 349*ff0253f9SPatrick Williamsthat they are valid under applicable law. If additional permissions 350*ff0253f9SPatrick Williamsapply only to part of the Program, that part may be used separately 351*ff0253f9SPatrick Williamsunder those permissions, but the entire Program remains governed by 352*ff0253f9SPatrick Williamsthis License without regard to the additional permissions. 353*ff0253f9SPatrick Williams 354*ff0253f9SPatrick Williams When you convey a copy of a covered work, you may at your option 355*ff0253f9SPatrick Williamsremove any additional permissions from that copy, or from any part of 356*ff0253f9SPatrick Williamsit. (Additional permissions may be written to require their own 357*ff0253f9SPatrick Williamsremoval in certain cases when you modify the work.) You may place 358*ff0253f9SPatrick Williamsadditional permissions on material, added by you to a covered work, 359*ff0253f9SPatrick Williamsfor which you have or can give appropriate copyright permission. 360*ff0253f9SPatrick Williams 361*ff0253f9SPatrick Williams Notwithstanding any other provision of this License, for material you 362*ff0253f9SPatrick Williamsadd to a covered work, you may (if authorized by the copyright holders of 363*ff0253f9SPatrick Williamsthat material) supplement the terms of this License with terms: 364*ff0253f9SPatrick Williams 365*ff0253f9SPatrick Williams a) Disclaiming warranty or limiting liability differently from the 366*ff0253f9SPatrick Williams terms of sections 15 and 16 of this License; or 367*ff0253f9SPatrick Williams 368*ff0253f9SPatrick Williams b) Requiring preservation of specified reasonable legal notices or 369*ff0253f9SPatrick Williams author attributions in that material or in the Appropriate Legal 370*ff0253f9SPatrick Williams Notices displayed by works containing it; or 371*ff0253f9SPatrick Williams 372*ff0253f9SPatrick Williams c) Prohibiting misrepresentation of the origin of that material, or 373*ff0253f9SPatrick Williams requiring that modified versions of such material be marked in 374*ff0253f9SPatrick Williams reasonable ways as different from the original version; or 375*ff0253f9SPatrick Williams 376*ff0253f9SPatrick Williams d) Limiting the use for publicity purposes of names of licensors or 377*ff0253f9SPatrick Williams authors of the material; or 378*ff0253f9SPatrick Williams 379*ff0253f9SPatrick Williams e) Declining to grant rights under trademark law for use of some 380*ff0253f9SPatrick Williams trade names, trademarks, or service marks; or 381*ff0253f9SPatrick Williams 382*ff0253f9SPatrick Williams f) Requiring indemnification of licensors and authors of that 383*ff0253f9SPatrick Williams material by anyone who conveys the material (or modified versions of 384*ff0253f9SPatrick Williams it) with contractual assumptions of liability to the recipient, for 385*ff0253f9SPatrick Williams any liability that these contractual assumptions directly impose on 386*ff0253f9SPatrick Williams those licensors and authors. 387*ff0253f9SPatrick Williams 388*ff0253f9SPatrick Williams All other non-permissive additional terms are considered "further 389*ff0253f9SPatrick Williamsrestrictions" within the meaning of section 10. If the Program as you 390*ff0253f9SPatrick Williamsreceived it, or any part of it, contains a notice stating that it is 391*ff0253f9SPatrick Williamsgoverned by this License along with a term that is a further 392*ff0253f9SPatrick Williamsrestriction, you may remove that term. If a license document contains 393*ff0253f9SPatrick Williamsa further restriction but permits relicensing or conveying under this 394*ff0253f9SPatrick WilliamsLicense, you may add to a covered work material governed by the terms 395*ff0253f9SPatrick Williamsof that license document, provided that the further restriction does 396*ff0253f9SPatrick Williamsnot survive such relicensing or conveying. 397*ff0253f9SPatrick Williams 398*ff0253f9SPatrick Williams If you add terms to a covered work in accord with this section, you 399*ff0253f9SPatrick Williamsmust place, in the relevant source files, a statement of the 400*ff0253f9SPatrick Williamsadditional terms that apply to those files, or a notice indicating 401*ff0253f9SPatrick Williamswhere to find the applicable terms. 402*ff0253f9SPatrick Williams 403*ff0253f9SPatrick Williams Additional terms, permissive or non-permissive, may be stated in the 404*ff0253f9SPatrick Williamsform of a separately written license, or stated as exceptions; 405*ff0253f9SPatrick Williamsthe above requirements apply either way. 406*ff0253f9SPatrick Williams 407*ff0253f9SPatrick Williams 8. Termination. 408*ff0253f9SPatrick Williams 409*ff0253f9SPatrick Williams You may not propagate or modify a covered work except as expressly 410*ff0253f9SPatrick Williamsprovided under this License. Any attempt otherwise to propagate or 411*ff0253f9SPatrick Williamsmodify it is void, and will automatically terminate your rights under 412*ff0253f9SPatrick Williamsthis License (including any patent licenses granted under the third 413*ff0253f9SPatrick Williamsparagraph of section 11). 414*ff0253f9SPatrick Williams 415*ff0253f9SPatrick Williams However, if you cease all violation of this License, then your 416*ff0253f9SPatrick Williamslicense from a particular copyright holder is reinstated (a) 417*ff0253f9SPatrick Williamsprovisionally, unless and until the copyright holder explicitly and 418*ff0253f9SPatrick Williamsfinally terminates your license, and (b) permanently, if the copyright 419*ff0253f9SPatrick Williamsholder fails to notify you of the violation by some reasonable means 420*ff0253f9SPatrick Williamsprior to 60 days after the cessation. 421*ff0253f9SPatrick Williams 422*ff0253f9SPatrick Williams Moreover, your license from a particular copyright holder is 423*ff0253f9SPatrick Williamsreinstated permanently if the copyright holder notifies you of the 424*ff0253f9SPatrick Williamsviolation by some reasonable means, this is the first time you have 425*ff0253f9SPatrick Williamsreceived notice of violation of this License (for any work) from that 426*ff0253f9SPatrick Williamscopyright holder, and you cure the violation prior to 30 days after 427*ff0253f9SPatrick Williamsyour receipt of the notice. 428*ff0253f9SPatrick Williams 429*ff0253f9SPatrick Williams Termination of your rights under this section does not terminate the 430*ff0253f9SPatrick Williamslicenses of parties who have received copies or rights from you under 431*ff0253f9SPatrick Williamsthis License. If your rights have been terminated and not permanently 432*ff0253f9SPatrick Williamsreinstated, you do not qualify to receive new licenses for the same 433*ff0253f9SPatrick Williamsmaterial under section 10. 434*ff0253f9SPatrick Williams 435*ff0253f9SPatrick Williams 9. Acceptance Not Required for Having Copies. 436*ff0253f9SPatrick Williams 437*ff0253f9SPatrick Williams You are not required to accept this License in order to receive or 438*ff0253f9SPatrick Williamsrun a copy of the Program. Ancillary propagation of a covered work 439*ff0253f9SPatrick Williamsoccurring solely as a consequence of using peer-to-peer transmission 440*ff0253f9SPatrick Williamsto receive a copy likewise does not require acceptance. However, 441*ff0253f9SPatrick Williamsnothing other than this License grants you permission to propagate or 442*ff0253f9SPatrick Williamsmodify any covered work. These actions infringe copyright if you do 443*ff0253f9SPatrick Williamsnot accept this License. Therefore, by modifying or propagating a 444*ff0253f9SPatrick Williamscovered work, you indicate your acceptance of this License to do so. 445*ff0253f9SPatrick Williams 446*ff0253f9SPatrick Williams 10. Automatic Licensing of Downstream Recipients. 447*ff0253f9SPatrick Williams 448*ff0253f9SPatrick Williams Each time you convey a covered work, the recipient automatically 449*ff0253f9SPatrick Williamsreceives a license from the original licensors, to run, modify and 450*ff0253f9SPatrick Williamspropagate that work, subject to this License. You are not responsible 451*ff0253f9SPatrick Williamsfor enforcing compliance by third parties with this License. 452*ff0253f9SPatrick Williams 453*ff0253f9SPatrick Williams An "entity transaction" is a transaction transferring control of an 454*ff0253f9SPatrick Williamsorganization, or substantially all assets of one, or subdividing an 455*ff0253f9SPatrick Williamsorganization, or merging organizations. If propagation of a covered 456*ff0253f9SPatrick Williamswork results from an entity transaction, each party to that 457*ff0253f9SPatrick Williamstransaction who receives a copy of the work also receives whatever 458*ff0253f9SPatrick Williamslicenses to the work the party's predecessor in interest had or could 459*ff0253f9SPatrick Williamsgive under the previous paragraph, plus a right to possession of the 460*ff0253f9SPatrick WilliamsCorresponding Source of the work from the predecessor in interest, if 461*ff0253f9SPatrick Williamsthe predecessor has it or can get it with reasonable efforts. 462*ff0253f9SPatrick Williams 463*ff0253f9SPatrick Williams You may not impose any further restrictions on the exercise of the 464*ff0253f9SPatrick Williamsrights granted or affirmed under this License. For example, you may 465*ff0253f9SPatrick Williamsnot impose a license fee, royalty, or other charge for exercise of 466*ff0253f9SPatrick Williamsrights granted under this License, and you may not initiate litigation 467*ff0253f9SPatrick Williams(including a cross-claim or counterclaim in a lawsuit) alleging that 468*ff0253f9SPatrick Williamsany patent claim is infringed by making, using, selling, offering for 469*ff0253f9SPatrick Williamssale, or importing the Program or any portion of it. 470*ff0253f9SPatrick Williams 471*ff0253f9SPatrick Williams 11. Patents. 472*ff0253f9SPatrick Williams 473*ff0253f9SPatrick Williams A "contributor" is a copyright holder who authorizes use under this 474*ff0253f9SPatrick WilliamsLicense of the Program or a work on which the Program is based. The 475*ff0253f9SPatrick Williamswork thus licensed is called the contributor's "contributor version". 476*ff0253f9SPatrick Williams 477*ff0253f9SPatrick Williams A contributor's "essential patent claims" are all patent claims 478*ff0253f9SPatrick Williamsowned or controlled by the contributor, whether already acquired or 479*ff0253f9SPatrick Williamshereafter acquired, that would be infringed by some manner, permitted 480*ff0253f9SPatrick Williamsby this License, of making, using, or selling its contributor version, 481*ff0253f9SPatrick Williamsbut do not include claims that would be infringed only as a 482*ff0253f9SPatrick Williamsconsequence of further modification of the contributor version. For 483*ff0253f9SPatrick Williamspurposes of this definition, "control" includes the right to grant 484*ff0253f9SPatrick Williamspatent sublicenses in a manner consistent with the requirements of 485*ff0253f9SPatrick Williamsthis License. 486*ff0253f9SPatrick Williams 487*ff0253f9SPatrick Williams Each contributor grants you a non-exclusive, worldwide, royalty-free 488*ff0253f9SPatrick Williamspatent license under the contributor's essential patent claims, to 489*ff0253f9SPatrick Williamsmake, use, sell, offer for sale, import and otherwise run, modify and 490*ff0253f9SPatrick Williamspropagate the contents of its contributor version. 491*ff0253f9SPatrick Williams 492*ff0253f9SPatrick Williams In the following three paragraphs, a "patent license" is any express 493*ff0253f9SPatrick Williamsagreement or commitment, however denominated, not to enforce a patent 494*ff0253f9SPatrick Williams(such as an express permission to practice a patent or covenant not to 495*ff0253f9SPatrick Williamssue for patent infringement). To "grant" such a patent license to a 496*ff0253f9SPatrick Williamsparty means to make such an agreement or commitment not to enforce a 497*ff0253f9SPatrick Williamspatent against the party. 498*ff0253f9SPatrick Williams 499*ff0253f9SPatrick Williams If you convey a covered work, knowingly relying on a patent license, 500*ff0253f9SPatrick Williamsand the Corresponding Source of the work is not available for anyone 501*ff0253f9SPatrick Williamsto copy, free of charge and under the terms of this License, through a 502*ff0253f9SPatrick Williamspublicly available network server or other readily accessible means, 503*ff0253f9SPatrick Williamsthen you must either (1) cause the Corresponding Source to be so 504*ff0253f9SPatrick Williamsavailable, or (2) arrange to deprive yourself of the benefit of the 505*ff0253f9SPatrick Williamspatent license for this particular work, or (3) arrange, in a manner 506*ff0253f9SPatrick Williamsconsistent with the requirements of this License, to extend the patent 507*ff0253f9SPatrick Williamslicense to downstream recipients. "Knowingly relying" means you have 508*ff0253f9SPatrick Williamsactual knowledge that, but for the patent license, your conveying the 509*ff0253f9SPatrick Williamscovered work in a country, or your recipient's use of the covered work 510*ff0253f9SPatrick Williamsin a country, would infringe one or more identifiable patents in that 511*ff0253f9SPatrick Williamscountry that you have reason to believe are valid. 512*ff0253f9SPatrick Williams 513*ff0253f9SPatrick Williams If, pursuant to or in connection with a single transaction or 514*ff0253f9SPatrick Williamsarrangement, you convey, or propagate by procuring conveyance of, a 515*ff0253f9SPatrick Williamscovered work, and grant a patent license to some of the parties 516*ff0253f9SPatrick Williamsreceiving the covered work authorizing them to use, propagate, modify 517*ff0253f9SPatrick Williamsor convey a specific copy of the covered work, then the patent license 518*ff0253f9SPatrick Williamsyou grant is automatically extended to all recipients of the covered 519*ff0253f9SPatrick Williamswork and works based on it. 520*ff0253f9SPatrick Williams 521*ff0253f9SPatrick Williams A patent license is "discriminatory" if it does not include within 522*ff0253f9SPatrick Williamsthe scope of its coverage, prohibits the exercise of, or is 523*ff0253f9SPatrick Williamsconditioned on the non-exercise of one or more of the rights that are 524*ff0253f9SPatrick Williamsspecifically granted under this License. You may not convey a covered 525*ff0253f9SPatrick Williamswork if you are a party to an arrangement with a third party that is 526*ff0253f9SPatrick Williamsin the business of distributing software, under which you make payment 527*ff0253f9SPatrick Williamsto the third party based on the extent of your activity of conveying 528*ff0253f9SPatrick Williamsthe work, and under which the third party grants, to any of the 529*ff0253f9SPatrick Williamsparties who would receive the covered work from you, a discriminatory 530*ff0253f9SPatrick Williamspatent license (a) in connection with copies of the covered work 531*ff0253f9SPatrick Williamsconveyed by you (or copies made from those copies), or (b) primarily 532*ff0253f9SPatrick Williamsfor and in connection with specific products or compilations that 533*ff0253f9SPatrick Williamscontain the covered work, unless you entered into that arrangement, 534*ff0253f9SPatrick Williamsor that patent license was granted, prior to 28 March 2007. 535*ff0253f9SPatrick Williams 536*ff0253f9SPatrick Williams Nothing in this License shall be construed as excluding or limiting 537*ff0253f9SPatrick Williamsany implied license or other defenses to infringement that may 538*ff0253f9SPatrick Williamsotherwise be available to you under applicable patent law. 539*ff0253f9SPatrick Williams 540*ff0253f9SPatrick Williams 12. No Surrender of Others' Freedom. 541*ff0253f9SPatrick Williams 542*ff0253f9SPatrick Williams If conditions are imposed on you (whether by court order, agreement or 543*ff0253f9SPatrick Williamsotherwise) that contradict the conditions of this License, they do not 544*ff0253f9SPatrick Williamsexcuse you from the conditions of this License. If you cannot convey a 545*ff0253f9SPatrick Williamscovered work so as to satisfy simultaneously your obligations under this 546*ff0253f9SPatrick WilliamsLicense and any other pertinent obligations, then as a consequence you may 547*ff0253f9SPatrick Williamsnot convey it at all. For example, if you agree to terms that obligate you 548*ff0253f9SPatrick Williamsto collect a royalty for further conveying from those to whom you convey 549*ff0253f9SPatrick Williamsthe Program, the only way you could satisfy both those terms and this 550*ff0253f9SPatrick WilliamsLicense would be to refrain entirely from conveying the Program. 551*ff0253f9SPatrick Williams 552*ff0253f9SPatrick Williams 13. Use with the GNU Affero General Public License. 553*ff0253f9SPatrick Williams 554*ff0253f9SPatrick Williams Notwithstanding any other provision of this License, you have 555*ff0253f9SPatrick Williamspermission to link or combine any covered work with a work licensed 556*ff0253f9SPatrick Williamsunder version 3 of the GNU Affero General Public License into a single 557*ff0253f9SPatrick Williamscombined work, and to convey the resulting work. The terms of this 558*ff0253f9SPatrick WilliamsLicense will continue to apply to the part which is the covered work, 559*ff0253f9SPatrick Williamsbut the special requirements of the GNU Affero General Public License, 560*ff0253f9SPatrick Williamssection 13, concerning interaction through a network will apply to the 561*ff0253f9SPatrick Williamscombination as such. 562*ff0253f9SPatrick Williams 563*ff0253f9SPatrick Williams 14. Revised Versions of this License. 564*ff0253f9SPatrick Williams 565*ff0253f9SPatrick Williams The Free Software Foundation may publish revised and/or new versions of 566*ff0253f9SPatrick Williamsthe GNU General Public License from time to time. Such new versions will 567*ff0253f9SPatrick Williamsbe similar in spirit to the present version, but may differ in detail to 568*ff0253f9SPatrick Williamsaddress new problems or concerns. 569*ff0253f9SPatrick Williams 570*ff0253f9SPatrick Williams Each version is given a distinguishing version number. If the 571*ff0253f9SPatrick WilliamsProgram specifies that a certain numbered version of the GNU General 572*ff0253f9SPatrick WilliamsPublic License "or any later version" applies to it, you have the 573*ff0253f9SPatrick Williamsoption of following the terms and conditions either of that numbered 574*ff0253f9SPatrick Williamsversion or of any later version published by the Free Software 575*ff0253f9SPatrick WilliamsFoundation. If the Program does not specify a version number of the 576*ff0253f9SPatrick WilliamsGNU General Public License, you may choose any version ever published 577*ff0253f9SPatrick Williamsby the Free Software Foundation. 578*ff0253f9SPatrick Williams 579*ff0253f9SPatrick Williams If the Program specifies that a proxy can decide which future 580*ff0253f9SPatrick Williamsversions of the GNU General Public License can be used, that proxy's 581*ff0253f9SPatrick Williamspublic statement of acceptance of a version permanently authorizes you 582*ff0253f9SPatrick Williamsto choose that version for the Program. 583*ff0253f9SPatrick Williams 584*ff0253f9SPatrick Williams Later license versions may give you additional or different 585*ff0253f9SPatrick Williamspermissions. However, no additional obligations are imposed on any 586*ff0253f9SPatrick Williamsauthor or copyright holder as a result of your choosing to follow a 587*ff0253f9SPatrick Williamslater version. 588*ff0253f9SPatrick Williams 589*ff0253f9SPatrick Williams 15.
