By contrast,  franta-hg@9  28 the GNU General Public License is intended to guarantee your freedom to  franta-hg@9  29 share and change all versions of a program--to make sure it remains free  franta-hg@9  30 software for all its users. We, the Free Software Foundation, use the  franta-hg@9  31 GNU General Public License for most of our software; it applies also to  franta-hg@9  32 any other work released this way by its authors. You can apply it to  franta-hg@9  33 your programs, too.  franta-hg@9  34 franta-hg@9  35 When we speak of free software, we are referring to freedom, not  franta-hg@9  36 price. Our General Public Licenses are designed to make sure that you  franta-hg@9  37 have the freedom to distribute copies of free software (and charge for  franta-hg@9  38 them if you wish), that you receive source code or can get it if you  franta-hg@9  39 want it, that you can change the software or use pieces of it in new  franta-hg@9  40 free programs, and that you know you can do these things.  franta-hg@9  41 franta-hg@9  42 To protect your rights, we need to prevent others from denying you  franta-hg@9  43 these rights or asking you to surrender the rights. Therefore, you have  franta-hg@9  44 certain responsibilities if you distribute copies of the software, or if  franta-hg@9  45 you modify it: responsibilities to respect the freedom of others.  franta-hg@9  46 franta-hg@9  47 For example, if you distribute copies of such a program, whether  franta-hg@9  48 gratis or for a fee, you must pass on to the recipients the same  franta-hg@9  49 freedoms that you received. You must make sure that they, too, receive  franta-hg@9  50 or can get the source code. And you must show them these terms so they  franta-hg@9  51 know their rights.  franta-hg@9  52 franta-hg@9  53 Developers that use the GNU GPL protect your rights with two steps:  franta-hg@9  54 (1) assert copyright on the software, and (2) offer you this License  franta-hg@9  55 giving you legal permission to copy, distribute and/or modify it.  franta-hg@9  56 franta-hg@9  57 For the developers' and authors' protection, the GPL clearly explains  franta-hg@9  58 that there is no warranty for this free software. For both users' and  franta-hg@9  59 authors' sake, the GPL requires that modified versions be marked as  franta-hg@9  60 changed, so that their problems will not be attributed erroneously to  franta-hg@9  61 authors of previous versions.  franta-hg@9  62 franta-hg@9  63 Some devices are designed to deny users access to install or run  franta-hg@9  64 modified versions of the software inside them, although the manufacturer  franta-hg@9  65 can do so. This is fundamentally incompatible with the aim of  franta-hg@9  66 protecting users' freedom to change the software. The systematic  franta-hg@9  67 pattern of such abuse occurs in the area of products for individuals to  franta-hg@9  68 use, which is precisely where it is most unacceptable. Therefore, we  franta-hg@9  69 have designed this version of the GPL to prohibit the practice for those  franta-hg@9  70 products. If such problems arise substantially in other domains, we  franta-hg@9  71 stand ready to extend this provision to those domains in future versions  franta-hg@9  72 of the GPL, as needed to protect the freedom of users.  franta-hg@9  73 franta-hg@9  74 Finally, every program is threatened constantly by software patents.  franta-hg@9  75 States should not allow patents to restrict development and use of  franta-hg@9  76 software on general-purpose computers, but in those that do, we wish to  franta-hg@9  77 avoid the special danger that patents applied to a free program could  franta-hg@9  78 make it effectively proprietary. To prevent this, the GPL assures that  franta-hg@9  79 patents cannot be used to render the program non-free.  franta-hg@9  80 franta-hg@9  81 The precise terms and conditions for copying, distribution and  franta-hg@9  82 modification follow.  franta-hg@9  83 \end{abstract}  franta-hg@9  84 franta-hg@9  85 \begin{center}  franta-hg@9  86 {\Large \sc Terms and Conditions}  franta-hg@9  87 \end{center}  franta-hg@9  88 franta-hg@9  89 franta-hg@9  90 \begin{enumerate}  franta-hg@9  91 franta-hg@9  92 \addtocounter{enumi}{-1}  franta-hg@9  93 franta-hg@9  94 \item Definitions.  franta-hg@9  95 franta-hg@9  96 This License'' refers to version 3 of the GNU General Public License.  franta-hg@9  97 franta-hg@9  98 Copyright'' also means copyright-like laws that apply to other kinds of  franta-hg@9  99 works, such as semiconductor masks.  franta-hg@9  100 franta-hg@9  101 The Program'' refers to any copyrightable work licensed under this  franta-hg@9  102 License. Each licensee is addressed as you''. Licensees'' and  franta-hg@9  103 recipients'' may be individuals or organizations.  franta-hg@9  104 franta-hg@9  105 To modify'' a work means to copy from or adapt all or part of the work  franta-hg@9  106 in a fashion requiring copyright permission, other than the making of an  franta-hg@9  107 exact copy. The resulting work is called a modified version'' of the  franta-hg@9  108 earlier work or a work based on'' the earlier work.  franta-hg@9  109 franta-hg@9  110 A covered work'' means either the unmodified Program or a work based  franta-hg@9  111 on the Program.  franta-hg@9  112 franta-hg@9  113 To propagate'' a work means to do anything with it that, without  franta-hg@9  114 permission, would make you directly or secondarily liable for  franta-hg@9  115 infringement under applicable copyright law, except executing it on a  franta-hg@9  116 computer or modifying a private copy. Propagation includes copying,  franta-hg@9  117 distribution (with or without modification), making available to the  franta-hg@9  118 public, and in some countries other activities as well.  franta-hg@9  119 franta-hg@9  120 To convey'' a work means any kind of propagation that enables other  franta-hg@9  121 parties to make or receive copies. Mere interaction with a user through  franta-hg@9  122 a computer network, with no transfer of a copy, is not conveying.  franta-hg@9  123 franta-hg@9  124 An interactive user interface displays Appropriate Legal Notices''  franta-hg@9  125 to the extent that it includes a convenient and prominently visible  franta-hg@9  126 feature that (1) displays an appropriate copyright notice, and (2)  franta-hg@9  127 tells the user that there is no warranty for the work (except to the  franta-hg@9  128 extent that warranties are provided), that licensees may convey the  franta-hg@9  129 work under this License, and how to view a copy of this License. If  franta-hg@9  130 the interface presents a list of user commands or options, such as a  franta-hg@9  131 menu, a prominent item in the list meets this criterion.  franta-hg@9  132 franta-hg@9  133 \item Source Code.  franta-hg@9  134 franta-hg@9  135 The source code'' for a work means the preferred form of the work  franta-hg@9  136 for making modifications to it. Object code'' means any non-source  franta-hg@9  137 form of a work.  franta-hg@9  138 franta-hg@9  139 A Standard Interface'' means an interface that either is an official  franta-hg@9  140 standard defined by a recognized standards body, or, in the case of  franta-hg@9  141 interfaces specified for a particular programming language, one that  franta-hg@9  142 is widely used among developers working in that language.  franta-hg@9  143 franta-hg@9  144 The System Libraries'' of an executable work include anything, other  franta-hg@9  145 than the work as a whole, that (a) is included in the normal form of  franta-hg@9  146 packaging a Major Component, but which is not part of that Major  franta-hg@9  147 Component, and (b) serves only to enable use of the work with that  franta-hg@9  148 Major Component, or to implement a Standard Interface for which an  franta-hg@9  149 implementation is available to the public in source code form. A  franta-hg@9  150 Major Component'', in this context, means a major essential component  franta-hg@9  151 (kernel, window system, and so on) of the specific operating system  franta-hg@9  152 (if any) on which the executable work runs, or a compiler used to  franta-hg@9  153 produce the work, or an object code interpreter used to run it.  franta-hg@9  154 franta-hg@9  155 The Corresponding Source'' for a work in object code form means all  franta-hg@9  156 the source code needed to generate, install, and (for an executable  franta-hg@9  157 work) run the object code and to modify the work, including scripts to  franta-hg@9  158 control those activities. However, it does not include the work's  franta-hg@9  159 System Libraries, or general-purpose tools or generally available free  franta-hg@9  160 programs which are used unmodified in performing those activities but  franta-hg@9  161 which are not part of the work. For example, Corresponding Source  franta-hg@9  162 includes interface definition files associated with source files for  franta-hg@9  163 the work, and the source code for shared libraries and dynamically  franta-hg@9  164 linked subprograms that the work is specifically designed to require,  franta-hg@9  165 such as by intimate data communication or control flow between those  franta-hg@9  166 subprograms and other parts of the work.  franta-hg@9  167 franta-hg@9  168 The Corresponding Source need not include anything that users  franta-hg@9  169 can regenerate automatically from other parts of the Corresponding  franta-hg@9  170 Source.  franta-hg@9  171 franta-hg@9  172 The Corresponding Source for a work in source code form is that  franta-hg@9  173 same work.  franta-hg@9  174 franta-hg@9  175 \item Basic Permissions.  franta-hg@9  176 franta-hg@9  177 All rights granted under this License are granted for the term of  franta-hg@9  178 copyright on the Program, and are irrevocable provided the stated  franta-hg@9  179 conditions are met. This License explicitly affirms your unlimited  franta-hg@9  180 permission to run the unmodified Program. The output from running a  franta-hg@9  181 covered work is covered by this License only if the output, given its  franta-hg@9  182 content, constitutes a covered work. This License acknowledges your  franta-hg@9  183 rights of fair use or other equivalent, as provided by copyright law.  franta-hg@9  184 franta-hg@9  185 You may make, run and propagate covered works that you do not  franta-hg@9  186 convey, without conditions so long as your license otherwise remains  franta-hg@9  187 in force. You may convey covered works to others for the sole purpose  franta-hg@9  188 of having them make modifications exclusively for you, or provide you  franta-hg@9  189 with facilities for running those works, provided that you comply with  franta-hg@9  190 the terms of this License in conveying all material for which you do  franta-hg@9  191 not control copyright. Those thus making or running the covered works  franta-hg@9  192 for you must do so exclusively on your behalf, under your direction  franta-hg@9  193 and control, on terms that prohibit them from making any copies of  franta-hg@9  194 your copyrighted material outside their relationship with you.  franta-hg@9  195 franta-hg@9  196 Conveying under any other circumstances is permitted solely under  franta-hg@9  197 the conditions stated below. Sublicensing is not allowed; section 10  franta-hg@9  198 makes it unnecessary.  franta-hg@9  199 franta-hg@9  200 \item Protecting Users' Legal Rights From Anti-Circumvention Law.  franta-hg@9  201 franta-hg@9  202 No covered work shall be deemed part of an effective technological  franta-hg@9  203 measure under any applicable law fulfilling obligations under article  franta-hg@9  204 11 of the WIPO copyright treaty adopted on 20 December 1996, or  franta-hg@9  205 similar laws prohibiting or restricting circumvention of such  franta-hg@9  206 measures.  franta-hg@9  207 franta-hg@9  208 When you convey a covered work, you waive any legal power to forbid  franta-hg@9  209 circumvention of technological measures to the extent such circumvention  franta-hg@9  210 is effected by exercising rights under this License with respect to  franta-hg@9  211 the covered work, and you disclaim any intention to limit operation or  franta-hg@9  212 modification of the work as a means of enforcing, against the work's  franta-hg@9  213 users, your or third parties' legal rights to forbid circumvention of  franta-hg@9  214 technological measures.  franta-hg@9  215 franta-hg@9  216 \item Conveying Verbatim Copies.  franta-hg@9  217 franta-hg@9  218 You may convey verbatim copies of the Program's source code as you  franta-hg@9  219 receive it, in any medium, provided that you conspicuously and  franta-hg@9  220 appropriately publish on each copy an appropriate copyright notice;  franta-hg@9  221 keep intact all notices stating that this License and any  franta-hg@9  222 non-permissive terms added in accord with section 7 apply to the code;  franta-hg@9  223 keep intact all notices of the absence of any warranty; and give all  franta-hg@9  224 recipients a copy of this License along with the Program.  franta-hg@9  225 franta-hg@9  226 You may charge any price or no price for each copy that you convey,  franta-hg@9  227 and you may offer support or warranty protection for a fee.  franta-hg@9  228 franta-hg@9  229 \item Conveying Modified Source Versions.  franta-hg@9  230 franta-hg@9  231 You may convey a work based on the Program, or the modifications to  franta-hg@9  232 produce it from the Program, in the form of source code under the  franta-hg@9  233 terms of section 4, provided that you also meet all of these conditions:  franta-hg@9  234  \begin{enumerate}  franta-hg@9  235  \item The work must carry prominent notices stating that you modified  franta-hg@9  236  it, and giving a relevant date.  franta-hg@9  237 franta-hg@9  238  \item The work must carry prominent notices stating that it is  franta-hg@9  239  released under this License and any conditions added under section  franta-hg@9  240  7. This requirement modifies the requirement in section 4 to  franta-hg@9  241  keep intact all notices''.  franta-hg@9  242 franta-hg@9  243  \item You must license the entire work, as a whole, under this  franta-hg@9  244  License to anyone who comes into possession of a copy. This  franta-hg@9  245  License will therefore apply, along with any applicable section 7  franta-hg@9  246  additional terms, to the whole of the work, and all its parts,  franta-hg@9  247  regardless of how they are packaged. This License gives no  franta-hg@9  248  permission to license the work in any other way, but it does not  franta-hg@9  249  invalidate such permission if you have separately received it.  franta-hg@9  250 franta-hg@9  251  \item If the work has interactive user interfaces, each must display  franta-hg@9  252  Appropriate Legal Notices; however, if the Program has interactive  franta-hg@9  253  interfaces that do not display Appropriate Legal Notices, your  franta-hg@9  254  work need not make them do so.  franta-hg@9  255 \end{enumerate}  franta-hg@9  256 A compilation of a covered work with other separate and independent  franta-hg@9  257 works, which are not by their nature extensions of the covered work,  franta-hg@9  258 and which are not combined with it such as to form a larger program,  franta-hg@9  259 in or on a volume of a storage or distribution medium, is called an  franta-hg@9  260 aggregate'' if the compilation and its resulting copyright are not  franta-hg@9  261 used to limit the access or legal rights of the compilation's users  franta-hg@9  262 beyond what the individual works permit. Inclusion of a covered work  franta-hg@9  263 in an aggregate does not cause this License to apply to the other  franta-hg@9  264 parts of the aggregate.  franta-hg@9  265 franta-hg@9  266 \item Conveying Non-Source Forms.  franta-hg@9  267 franta-hg@9  268 You may convey a covered work in object code form under the terms  franta-hg@9  269 of sections 4 and 5, provided that you also convey the  franta-hg@9  270 machine-readable Corresponding Source under the terms of this License,  franta-hg@9  271 in one of these ways:  franta-hg@9  272  \begin{enumerate}  franta-hg@9  273  \item Convey the object code in, or embodied in, a physical product  franta-hg@9  274  (including a physical distribution medium), accompanied by the  franta-hg@9  275  Corresponding Source fixed on a durable physical medium  franta-hg@9  276  customarily used for software interchange.  franta-hg@9  277 franta-hg@9  278  \item Convey the object code in, or embodied in, a physical product  franta-hg@9  279  (including a physical distribution medium), accompanied by a  franta-hg@9  280  written offer, valid for at least three years and valid for as  franta-hg@9  281  long as you offer spare parts or customer support for that product  franta-hg@9  282  model, to give anyone who possesses the object code either (1) a  franta-hg@9  283  copy of the Corresponding Source for all the software in the  franta-hg@9  284  product that is covered by this License, on a durable physical  franta-hg@9  285  medium customarily used for software interchange, for a price no  franta-hg@9  286  more than your reasonable cost of physically performing this  franta-hg@9  287  conveying of source, or (2) access to copy the  franta-hg@9  288  Corresponding Source from a network server at no charge.  franta-hg@9  289 franta-hg@9  290  \item Convey individual copies of the object code with a copy of the  franta-hg@9  291  written offer to provide the Corresponding Source. This  franta-hg@9  292  alternative is allowed only occasionally and noncommercially, and  franta-hg@9  293  only if you received the object code with such an offer, in accord  franta-hg@9  294  with subsection 6b.  franta-hg@9  295 franta-hg@9  296  \item Convey the object code by offering access from a designated  franta-hg@9  297  place (gratis or for a charge), and offer equivalent access to the  franta-hg@9  298  Corresponding Source in the same way through the same place at no  franta-hg@9  299  further charge. You need not require recipients to copy the  franta-hg@9  300  Corresponding Source along with the object code. If the place to  franta-hg@9  301  copy the object code is a network server, the Corresponding Source  franta-hg@9  302  may be on a different server (operated by you or a third party)  franta-hg@9  303  that supports equivalent copying facilities, provided you maintain  franta-hg@9  304  clear directions next to the object code saying where to find the  franta-hg@9  305  Corresponding Source. Regardless of what server hosts the  franta-hg@9  306  Corresponding Source, you remain obligated to ensure that it is  franta-hg@9  307  available for as long as needed to satisfy these requirements.  franta-hg@9  308 franta-hg@9  309  \item Convey the object code using peer-to-peer transmission, provided  franta-hg@9  310  you inform other peers where the object code and Corresponding  franta-hg@9  311  Source of the work are being offered to the general public at no  franta-hg@9  312  charge under subsection 6d.  franta-hg@9  313  \end{enumerate}  franta-hg@9  314 franta-hg@9  315 A separable portion of the object code, whose source code is excluded  franta-hg@9  316 from the Corresponding Source as a System Library, need not be  franta-hg@9  317 included in conveying the object code work.  franta-hg@9  318 franta-hg@9  319 A User Product'' is either (1) a consumer product'', which means any  franta-hg@9  320 tangible personal property which is normally used for personal, family,  franta-hg@9  321 or household purposes, or (2) anything designed or sold for incorporation  franta-hg@9  322 into a dwelling. In determining whether a product is a consumer product,  franta-hg@9  323 doubtful cases shall be resolved in favor of coverage. For a particular  franta-hg@9  324 product received by a particular user, normally used'' refers to a  franta-hg@9  325 typical or common use of that class of product, regardless of the status  franta-hg@9  326 of the particular user or of the way in which the particular user  franta-hg@9  327 actually uses, or expects or is expected to use, the product. A product  franta-hg@9  328 is a consumer product regardless of whether the product has substantial  franta-hg@9  329 commercial, industrial or non-consumer uses, unless such uses represent  franta-hg@9  330 the only significant mode of use of the product.  franta-hg@9  331 franta-hg@9  332 Installation Information'' for a User Product means any methods,  franta-hg@9  333 procedures, authorization keys, or other information required to install  franta-hg@9  334 and execute modified versions of a covered work in that User Product from  franta-hg@9  335 a modified version of its Corresponding Source. The information must  franta-hg@9  336 suffice to ensure that the continued functioning of the modified object  franta-hg@9  337 code is in no case prevented or interfered with solely because  franta-hg@9  338 modification has been made.  franta-hg@9  339 franta-hg@9  340 If you convey an object code work under this section in, or with, or  franta-hg@9  341 specifically for use in, a User Product, and the conveying occurs as  franta-hg@9  342 part of a transaction in which the right of possession and use of the  franta-hg@9  343 User Product is transferred to the recipient in perpetuity or for a  franta-hg@9  344 fixed term (regardless of how the transaction is characterized), the  franta-hg@9  345 Corresponding Source conveyed under this section must be accompanied  franta-hg@9  346 by the Installation Information. But this requirement does not apply  franta-hg@9  347 if neither you nor any third party retains the ability to install  franta-hg@9  348 modified object code on the User Product (for example, the work has  franta-hg@9  349 been installed in ROM).  franta-hg@9  350 franta-hg@9  351 The requirement to provide Installation Information does not include a  franta-hg@9  352 requirement to continue to provide support service, warranty, or updates  franta-hg@9  353 for a work that has been modified or installed by the recipient, or for  franta-hg@9  354 the User Product in which it has been modified or installed. Access to a  franta-hg@9  355 network may be denied when the modification itself materially and  franta-hg@9  356 adversely affects the operation of the network or violates the rules and  franta-hg@9  357 protocols for communication across the network.  franta-hg@9  358 franta-hg@9  359 Corresponding Source conveyed, and Installation Information provided,  franta-hg@9  360 in accord with this section must be in a format that is publicly  franta-hg@9  361 documented (and with an implementation available to the public in  franta-hg@9  362 source code form), and must require no special password or key for  franta-hg@9  363 unpacking, reading or copying.  franta-hg@9  364 franta-hg@9  365 \item Additional Terms.  franta-hg@9  366 franta-hg@9  367 Additional permissions'' are terms that supplement the terms of this  franta-hg@9  368 License by making exceptions from one or more of its conditions.  franta-hg@9  369 Additional permissions that are applicable to the entire Program shall  franta-hg@9  370 be treated as though they were included in this License, to the extent  franta-hg@9  371 that they are valid under applicable law. If additional permissions  franta-hg@9  372 apply only to part of the Program, that part may be used separately  franta-hg@9  373 under those permissions, but the entire Program remains governed by  franta-hg@9  374 this License without regard to the additional permissions.  franta-hg@9  375 franta-hg@9  376 When you convey a copy of a covered work, you may at your option  franta-hg@9  377 remove any additional permissions from that copy, or from any part of  franta-hg@9  378 it. (Additional permissions may be written to require their own  franta-hg@9  379 removal in certain cases when you modify the work.) You may place  franta-hg@9  380 additional permissions on material, added by you to a covered work,  franta-hg@9  381 for which you have or can give appropriate copyright permission.  franta-hg@9  382 franta-hg@9  383 Notwithstanding any other provision of this License, for material you  franta-hg@9  384 add to a covered work, you may (if authorized by the copyright holders of  franta-hg@9  385 that material) supplement the terms of this License with terms:  franta-hg@9  386  \begin{enumerate}  franta-hg@9  387  \item Disclaiming warranty or limiting liability differently from the  franta-hg@9  388  terms of sections 15 and 16 of this License; or  franta-hg@9  389 franta-hg@9  390  \item Requiring preservation of specified reasonable legal notices or  franta-hg@9  391  author attributions in that material or in the Appropriate Legal  franta-hg@9  392  Notices displayed by works containing it; or  franta-hg@9  393 franta-hg@9  394  \item Prohibiting misrepresentation of the origin of that material, or  franta-hg@9  395  requiring that modified versions of such material be marked in  franta-hg@9  396  reasonable ways as different from the original version; or  franta-hg@9  397 franta-hg@9  398  \item Limiting the use for publicity purposes of names of licensors or  franta-hg@9  399  authors of the material; or  franta-hg@9  400 franta-hg@9  401  \item Declining to grant rights under trademark law for use of some  franta-hg@9  402  trade names, trademarks, or service marks; or  franta-hg@9  403 franta-hg@9  404  \item Requiring indemnification of licensors and authors of that  franta-hg@9  405  material by anyone who conveys the material (or modified versions of  franta-hg@9  406  it) with contractual assumptions of liability to the recipient, for  franta-hg@9  407  any liability that these contractual assumptions directly impose on  franta-hg@9  408  those licensors and authors.  franta-hg@9  409  \end{enumerate}  franta-hg@9  410 franta-hg@9  411 All other non-permissive additional terms are considered further  franta-hg@9  412 restrictions'' within the meaning of section 10. If the Program as you  franta-hg@9  413 received it, or any part of it, contains a notice stating that it is  franta-hg@9  414 governed by this License along with a term that is a further  franta-hg@9  415 restriction, you may remove that term. If a license document contains  franta-hg@9  416 a further restriction but permits relicensing or conveying under this  franta-hg@9  417 License, you may add to a covered work material governed by the terms  franta-hg@9  418 of that license document, provided that the further restriction does  franta-hg@9  419 not survive such relicensing or conveying.  franta-hg@9  420 franta-hg@9  421 If you add terms to a covered work in accord with this section, you  franta-hg@9  422 must place, in the relevant source files, a statement of the  franta-hg@9  423 additional terms that apply to those files, or a notice indicating  franta-hg@9  424 where to find the applicable terms.  franta-hg@9  425 franta-hg@9  426 Additional terms, permissive or non-permissive, may be stated in the  franta-hg@9  427 form of a separately written license, or stated as exceptions;  franta-hg@9  428 the above requirements apply either way.  franta-hg@9  429 franta-hg@9  430 \item Termination.  franta-hg@9  431 franta-hg@9  432 You may not propagate or modify a covered work except as expressly  franta-hg@9  433 provided under this License. Any attempt otherwise to propagate or  franta-hg@9  434 modify it is void, and will automatically terminate your rights under  franta-hg@9  435 this License (including any patent licenses granted under the third  franta-hg@9  436 paragraph of section 11).  franta-hg@9  437 franta-hg@9  438 However, if you cease all violation of this License, then your  franta-hg@9  439 license from a particular copyright holder is reinstated (a)  franta-hg@9  440 provisionally, unless and until the copyright holder explicitly and  franta-hg@9  441 finally terminates your license, and (b) permanently, if the copyright  franta-hg@9  442 holder fails to notify you of the violation by some reasonable means  franta-hg@9  443 prior to 60 days after the cessation.  franta-hg@9  444 franta-hg@9  445 Moreover, your license from a particular copyright holder is  franta-hg@9  446 reinstated permanently if the copyright holder notifies you of the  franta-hg@9  447 violation by some reasonable means, this is the first time you have  franta-hg@9  448 received notice of violation of this License (for any work) from that  franta-hg@9  449 copyright holder, and you cure the violation prior to 30 days after  franta-hg@9  450 your receipt of the notice.  franta-hg@9  451 franta-hg@9  452 Termination of your rights under this section does not terminate the  franta-hg@9  453 licenses of parties who have received copies or rights from you under  franta-hg@9  454 this License. If your rights have been terminated and not permanently  franta-hg@9  455 reinstated, you do not qualify to receive new licenses for the same  franta-hg@9  456 material under section 10.  franta-hg@9  457 franta-hg@9  458 \item Acceptance Not Required for Having Copies.  franta-hg@9  459 franta-hg@9  460 You are not required to accept this License in order to receive or  franta-hg@9  461 run a copy of the Program. Ancillary propagation of a covered work  franta-hg@9  462 occurring solely as a consequence of using peer-to-peer transmission  franta-hg@9  463 to receive a copy likewise does not require acceptance. However,  franta-hg@9  464 nothing other than this License grants you permission to propagate or  franta-hg@9  465 modify any covered work. These actions infringe copyright if you do  franta-hg@9  466 not accept this License. Therefore, by modifying or propagating a  franta-hg@9  467 covered work, you indicate your acceptance of this License to do so.  franta-hg@9  468 franta-hg@9  469 \item Automatic Licensing of Downstream Recipients.  franta-hg@9  470 franta-hg@9  471 Each time you convey a covered work, the recipient automatically  franta-hg@9  472 receives a license from the original licensors, to run, modify and  franta-hg@9  473 propagate that work, subject to this License. You are not responsible  franta-hg@9  474 for enforcing compliance by third parties with this License.  franta-hg@9  475 franta-hg@9  476 An entity transaction'' is a transaction transferring control of an  franta-hg@9  477 organization, or substantially all assets of one, or subdividing an  franta-hg@9  478 organization, or merging organizations. If propagation of a covered  franta-hg@9  479 work results from an entity transaction, each party to that  franta-hg@9  480 transaction who receives a copy of the work also receives whatever  franta-hg@9  481 licenses to the work the party's predecessor in interest had or could  franta-hg@9  482 give under the previous paragraph, plus a right to possession of the  franta-hg@9  483 Corresponding Source of the work from the predecessor in interest, if  franta-hg@9  484 the predecessor has it or can get it with reasonable efforts.  franta-hg@9  485 franta-hg@9  486 You may not impose any further restrictions on the exercise of the  franta-hg@9  487 rights granted or affirmed under this License. For example, you may  franta-hg@9  488 not impose a license fee, royalty, or other charge for exercise of  franta-hg@9  489 rights granted under this License, and you may not initiate litigation  franta-hg@9  490 (including a cross-claim or counterclaim in a lawsuit) alleging that  franta-hg@9  491 any patent claim is infringed by making, using, selling, offering for  franta-hg@9  492 sale, or importing the Program or any portion of it.  franta-hg@9  493 franta-hg@9  494 \item Patents.  franta-hg@9  495 franta-hg@9  496 A contributor'' is a copyright holder who authorizes use under this  franta-hg@9  497 License of the Program or a work on which the Program is based. The  franta-hg@9  498 work thus licensed is called the contributor's contributor version''.  franta-hg@9  499 franta-hg@9  500 A contributor's essential patent claims'' are all patent claims  franta-hg@9  501 owned or controlled by the contributor, whether already acquired or  franta-hg@9  502 hereafter acquired, that would be infringed by some manner, permitted  franta-hg@9  503 by this License, of making, using, or selling its contributor version,  franta-hg@9  504 but do not include claims that would be infringed only as a  franta-hg@9  505 consequence of further modification of the contributor version. For  franta-hg@9  506 purposes of this definition, control'' includes the right to grant  franta-hg@9  507 patent sublicenses in a manner consistent with the requirements of  franta-hg@9  508 this License.  franta-hg@9  509 franta-hg@9  510 Each contributor grants you a non-exclusive, worldwide, royalty-free  franta-hg@9  511 patent license under the contributor's essential patent claims, to  franta-hg@9  512 make, use, sell, offer for sale, import and otherwise run, modify and  franta-hg@9  513 propagate the contents of its contributor version.  franta-hg@9  514 franta-hg@9  515 In the following three paragraphs, a patent license'' is any express  franta-hg@9  516 agreement or commitment, however denominated, not to enforce a patent  franta-hg@9  517 (such as an express permission to practice a patent or covenant not to  franta-hg@9  518 sue for patent infringement). To grant'' such a patent license to a  franta-hg@9  519 party means to make such an agreement or commitment not to enforce a  franta-hg@9  520 patent against the party.  franta-hg@9  521 franta-hg@9  522 If you convey a covered work, knowingly relying on a patent license,  franta-hg@9  523 and the Corresponding Source of the work is not available for anyone  franta-hg@9  524 to copy, free of charge and under the terms of this License, through a  franta-hg@9  525 publicly available network server or other readily accessible means,  franta-hg@9  526 then you must either (1) cause the Corresponding Source to be so  franta-hg@9  527 available, or (2) arrange to deprive yourself of the benefit of the  franta-hg@9  528 patent license for this particular work, or (3) arrange, in a manner  franta-hg@9  529 consistent with the requirements of this License, to extend the patent  franta-hg@9  530 license to downstream recipients. Knowingly relying'' means you have  franta-hg@9  531 actual knowledge that, but for the patent license, your conveying the  franta-hg@9  532 covered work in a country, or your recipient's use of the covered work  franta-hg@9  533 in a country, would infringe one or more identifiable patents in that  franta-hg@9  534 country that you have reason to believe are valid.  franta-hg@9  535 franta-hg@9  536 If, pursuant to or in connection with a single transaction or  franta-hg@9  537 arrangement, you convey, or propagate by procuring conveyance of, a  franta-hg@9  538 covered work, and grant a patent license to some of the parties  franta-hg@9  539 receiving the covered work authorizing them to use, propagate, modify  franta-hg@9  540 or convey a specific copy of the covered work, then the patent license  franta-hg@9  541 you grant is automatically extended to all recipients of the covered  franta-hg@9  542 work and works based on it.  franta-hg@9  543 franta-hg@9  544 A patent license is discriminatory'' if it does not include within  franta-hg@9  545 the scope of its coverage, prohibits the exercise of, or is  franta-hg@9  546 conditioned on the non-exercise of one or more of the rights that are  franta-hg@9  547 specifically granted under this License. You may not convey a covered  franta-hg@9  548 work if you are a party to an arrangement with a third party that is  franta-hg@9  549 in the business of distributing software, under which you make payment  franta-hg@9  550 to the third party based on the extent of your activity of conveying  franta-hg@9  551 the work, and under which the third party grants, to any of the  franta-hg@9  552 parties who would receive the covered work from you, a discriminatory  franta-hg@9  553 patent license (a) in connection with copies of the covered work  franta-hg@9  554 conveyed by you (or copies made from those copies), or (b) primarily  franta-hg@9  555 for and in connection with specific products or compilations that  franta-hg@9  556 contain the covered work, unless you entered into that arrangement,  franta-hg@9  557 or that patent license was granted, prior to 28 March 2007.  franta-hg@9  558 franta-hg@9  559 Nothing in this License shall be construed as excluding or limiting  franta-hg@9  560 any implied license or other defenses to infringement that may  franta-hg@9  561 otherwise be available to you under applicable patent law.  franta-hg@9  562 franta-hg@9  563 \item No Surrender of Others' Freedom.  franta-hg@9  564 franta-hg@9  565 If conditions are imposed on you (whether by court order, agreement or  franta-hg@9  566 otherwise) that contradict the conditions of this License, they do not  franta-hg@9  567 excuse you from the conditions of this License. If you cannot convey a  franta-hg@9  568 covered work so as to satisfy simultaneously your obligations under this  franta-hg@9  569 License and any other pertinent obligations, then as a consequence you may  franta-hg@9  570 not convey it at all. For example, if you agree to terms that obligate you  franta-hg@9  571 to collect a royalty for further conveying from those to whom you convey  franta-hg@9  572 the Program, the only way you could satisfy both those terms and this  franta-hg@9  573 License would be to refrain entirely from conveying the Program.  franta-hg@9  574 franta-hg@9  575 \item Use with the GNU Affero General Public License.  franta-hg@9  576 franta-hg@9  577 Notwithstanding any other provision of this License, you have  franta-hg@9  578 permission to link or combine any covered work with a work licensed  franta-hg@9  579 under version 3 of the GNU Affero General Public License into a single  franta-hg@9  580 combined work, and to convey the resulting work. The terms of this  franta-hg@9  581 License will continue to apply to the part which is the covered work,  franta-hg@9  582 but the special requirements of the GNU Affero General Public License,  franta-hg@9  583 section 13, concerning interaction through a network will apply to the  franta-hg@9  584 combination as such.  franta-hg@9  585 franta-hg@9  586 \item Revised Versions of this License.  franta-hg@9  587 franta-hg@9  588 The Free Software Foundation may publish revised and/or new versions of  franta-hg@9  589 the GNU General Public License from time to time. Such new versions will  franta-hg@9  590 be similar in spirit to the present version, but may differ in detail to  franta-hg@9  591 address new problems or concerns.  franta-hg@9  592 franta-hg@9  593 Each version is given a distinguishing version number. If the  franta-hg@9  594 Program specifies that a certain numbered version of the GNU General  franta-hg@9  595 Public License or any later version'' applies to it, you have the  franta-hg@9  596 option of following the terms and conditions either of that numbered  franta-hg@9  597 version or of any later version published by the Free Software  franta-hg@9  598 Foundation. If the Program does not specify a version number of the  franta-hg@9  599 GNU General Public License, you may choose any version ever published  franta-hg@9  600 by the Free Software Foundation.  franta-hg@9  601 franta-hg@9  602 If the Program specifies that a proxy can decide which future  franta-hg@9  603 versions of the GNU General Public License can be used, that proxy's  franta-hg@9  604 public statement of acceptance of a version permanently authorizes you  franta-hg@9  605 to choose that version for the Program.  franta-hg@9  606 franta-hg@9  607 Later license versions may give you additional or different  franta-hg@9  608 permissions. However, no additional obligations are imposed on any  franta-hg@9  609 author or copyright holder as a result of your choosing to follow a  franta-hg@9  610 later version.  franta-hg@9  611 franta-hg@9  612 \item Disclaimer of Warranty.  franta-hg@9  613 franta-hg@9  614 \begin{sloppypar}  franta-hg@9  615  THERE IS NO WARRANTY FOR THE PROGRAM, TO THE EXTENT PERMITTED BY  franta-hg@9  616  APPLICABLE LAW. EXCEPT WHEN OTHERWISE STATED IN WRITING THE  franta-hg@9  617  COPYRIGHT HOLDERS AND/OR OTHER PARTIES PROVIDE THE PROGRAM AS IS''  franta-hg@9  618  WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED OR IMPLIED,  franta-hg@9  619  INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF  franta-hg@9  620  MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. THE ENTIRE  franta-hg@9  621  RISK AS TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU.  franta-hg@9  622  SHOULD THE PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL  franta-hg@9  623  NECESSARY SERVICING, REPAIR OR CORRECTION.  franta-hg@9  624 \end{sloppypar}  franta-hg@9  625 franta-hg@9  626 \item Limitation of Liability.  franta-hg@9  627 franta-hg@9  628  IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN  franta-hg@9  629  WRITING WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MODIFIES  franta-hg@9  630  AND/OR CONVEYS THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR  franta-hg@9  631  DAMAGES, INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL  franta-hg@9  632  DAMAGES ARISING OUT OF THE USE OR INABILITY TO USE THE PROGRAM  franta-hg@9  633  (INCLUDING BUT NOT LIMITED TO LOSS OF DATA OR DATA BEING RENDERED  franta-hg@9  634  INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD PARTIES OR A FAILURE  franta-hg@9  635  OF THE PROGRAM TO OPERATE WITH ANY OTHER PROGRAMS), EVEN IF SUCH  franta-hg@9  636  HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH  franta-hg@9  637  DAMAGES.  franta-hg@9  638 franta-hg@9  639 \item Interpretation of Sections 15 and 16.  franta-hg@9  640 franta-hg@9  641 If the disclaimer of warranty and limitation of liability provided  franta-hg@9  642 above cannot be given local legal effect according to their terms,  franta-hg@9  643 reviewing courts shall apply local law that most closely approximates  franta-hg@9  644 an absolute waiver of all civil liability in connection with the  franta-hg@9  645 Program, unless a warranty or assumption of liability accompanies a  franta-hg@9  646 copy of the Program in return for a fee.  franta-hg@9  647 franta-hg@9  648 \begin{center}  franta-hg@9  649 {\Large\sc End of Terms and Conditions}  franta-hg@9  650 franta-hg@9  651 \bigskip  franta-hg@9  652 How to Apply These Terms to Your New Programs  franta-hg@9  653 \end{center}  franta-hg@9  654 franta-hg@9  655 If you develop a new program, and you want it to be of the greatest  franta-hg@9  656 possible use to the public, the best way to achieve this is to make it  franta-hg@9  657 free software which everyone can redistribute and change under these terms.  franta-hg@9  658 franta-hg@9  659 To do so, attach the following notices to the program. It is safest  franta-hg@9  660 to attach them to the start of each source file to most effectively  franta-hg@9  661 state the exclusion of warranty; and each file should have at least  franta-hg@9  662 the copyright'' line and a pointer to where the full notice is found.  franta-hg@9  663 franta-hg@9  664 {\footnotesize  franta-hg@9  665 \begin{verbatim}  franta-hg@9  666   franta-hg@9  667 franta-hg@9  668 Copyright (C)  franta-hg@9  669 franta-hg@9  670 This program is free software: you can redistribute it and/or modify  franta-hg@9  671 it under the terms of the GNU General Public License as published by  franta-hg@9  672 the Free Software Foundation, either version 3 of the License, or  franta-hg@9  673 (at your option) any later version.  franta-hg@9  674 franta-hg@9  675 This program is distributed in the hope that it will be useful,  franta-hg@9  676 but WITHOUT ANY WARRANTY; without even the implied warranty of  franta-hg@9  677 MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.
