hor_line_thick(); |

//-------------------------------------------------------------------------------- |
| 311 |
//doubtful cases shall be resolved in favor of coverage. For a particular |
//End of File |
| 312 |
//product received by a particular user, "normally used" refers to a |

| 313 |
//typical or common use of that class of product, regardless of the status |
?> |
|
//of the particular user or of the way in which the particular user |
|
|
//actually uses, or expects or is expected to use, the product. A product |
|
|
//is a consumer product regardless of whether the product has substantial |
|
|
//commercial, industrial or non-consumer uses, unless such uses represent |
|
|
//the only significant mode of use of the product. |

// "Installation Information" for a User Product means any methods, |
|
|
//procedures, authorization keys, or other information required to install |
|
|
//and execute modified versions of a covered work in that User Product from |
|
|
//a modified version of its Corresponding Source. The information must |
|
|
//suffice to ensure that the continued functioning of the modified object |
|
|
//code is in no case prevented or interfered with solely because |
|
|
//modification has been made. |
|
|
// |
|
|
// If you convey an object code work under this section in, or with, or |
|
|
//specifically for use in, a User Product, and the conveying occurs as |
|
|
//part of a transaction in which the right of possession and use of the |
|
|
//User Product is transferred to the recipient in perpetuity or for a |
|
|
//fixed term (regardless of how the transaction is characterized), the |
|
|
//Corresponding Source conveyed under this section must be accompanied |

//if neither you nor any third party retains the ability to install |
|
|
//modified object code on the User Product (for example, the work has |

//the User Product in which it has been modified or installed. Access to a |

// 7. Additional Terms. |
|
|
// |
|
|
// "Additional permissions" are terms that supplement the terms of this |
|
|
//License by making exceptions from one or more of its conditions. |
|
|
//Additional permissions that are applicable to the entire Program shall |
|
|
//be treated as though they were included in this License, to the extent |
|
|
//that they are valid under applicable law. If additional permissions |
|
|
//apply only to part of the Program, that part may be used separately |
|
|
//under those permissions, but the entire Program remains governed by |
|
|
//this License without regard to the additional permissions. |
|
|
// |
|
|
// When you convey a copy of a covered work, you may at your option |
|
|
//remove any additional permissions from that copy, or from any part of |
|
|
//it. (Additional permissions may be written to require their own |
|
|
//removal in certain cases when you modify the work.) You may place |
|
|
//additional permissions on material, added by you to a covered work, |
|
|
//for which you have or can give appropriate copyright permission. |
|
|
// |
|
|
// Notwithstanding any other provision of this License, for material you |
|
|
//add to a covered work, you may (if authorized by the copyright holders of |
|
|
//that material) supplement the terms of this License with terms: |
|
|
// |
|
|
// a) Disclaiming warranty or limiting liability differently from the |
|
|
// terms of sections 15 and 16 of this License; or |
|
|
// |
|
|
// b) Requiring preservation of specified reasonable legal notices or |
|
|
// author attributions in that material or in the Appropriate Legal |
|
|
// Notices displayed by works containing it; or |
|
|
// |
|
|
// c) Prohibiting misrepresentation of the origin of that material, or |
|
|
// requiring that modified versions of such material be marked in |
|
|
// reasonable ways as different from the original version; or |
|
|
// |
|
|
// d) Limiting the use for publicity purposes of names of licensors or |
|
|
// authors of the material; or |
|
|
// |
|
|
// e) Declining to grant rights under trademark law for use of some |
|
|
// trade names, trademarks, or service marks; or |
|
|
// |
|
|
// f) Requiring indemnification of licensors and authors of that |
|
|
// material by anyone who conveys the material (or modified versions of |
|
|
// it) with contractual assumptions of liability to the recipient, for |
|
|
// any liability that these contractual assumptions directly impose on |
|
|
// those licensors and authors. |
|
|
// |
|
|
// All other non-permissive additional terms are considered "further |
|
|
//restrictions" within the meaning of section 10. If the Program as you |
|
|
//received it, or any part of it, contains a notice stating that it is |
|
|
//governed by this License along with a term that is a further |
|
|
//restriction, you may remove that term. If a license document contains |
|
|
//a further restriction but permits relicensing or conveying under this |
|
|
//License, you may add to a covered work material governed by the terms |
|
|
//of that license document, provided that the further restriction does |
|
|
//not survive such relicensing or conveying. |
|
|
// |
|
|
// If you add terms to a covered work in accord with this section, you |
|
|
//must place, in the relevant source files, a statement of the |
|
|
//additional terms that apply to those files, or a notice indicating |
|
|
//where to find the applicable terms. |
|
|
// |
|
|
// Additional terms, permissive or non-permissive, may be stated in the |
|
|
//form of a separately written license, or stated as exceptions; |
|
|
//the above requirements apply either way. |
|
|
// |
|
|
// 8. Termination. |
|
|
// |
|
|
// You may not propagate or modify a covered work except as expressly |
|
|
//provided under this License. Any attempt otherwise to propagate or |
|
|
//modify it is void, and will automatically terminate your rights under |
|
|
//this License (including any patent licenses granted under the third |
|
|
//paragraph of section 11). |
|
|
// |
|
|
// However, if you cease all violation of this License, then your |
|
|
//license from a particular copyright holder is reinstated (a) |
|
|
//provisionally, unless and until the copyright holder explicitly and |
|
|
//finally terminates your license, and (b) permanently, if the copyright |
|
|
//holder fails to notify you of the violation by some reasonable means |
|
|
//prior to 60 days after the cessation. |
|
|
// |
|
|
// Moreover, your license from a particular copyright holder is |
|
|
//reinstated permanently if the copyright holder notifies you of the |
|
|
//violation by some reasonable means, this is the first time you have |
|
|
//received notice of violation of this License (for any work) from that |
|
|
//copyright holder, and you cure the violation prior to 30 days after |
|
|
//your receipt of the notice. |
|
|
// |
|
|
// Termination of your rights under this section does not terminate the |
|
|
//licenses of parties who have received copies or rights from you under |
|
|
//this License. If your rights have been terminated and not permanently |
|
|
//reinstated, you do not qualify to receive new licenses for the same |
|
|
//material under section 10. |
|
|
// |
|
|
// 9. Acceptance Not Required for Having Copies. |
|
|
// |
|
|
// You are not required to accept this License in order to receive or |
|
|
//run a copy of the Program. Ancillary propagation of a covered work |
|
|
//occurring solely as a consequence of using peer-to-peer transmission |
|
|
//to receive a copy likewise does not require acceptance. However, |
|
|
//nothing other than this License grants you permission to propagate or |
|
|
//modify any covered work. These actions infringe copyright if you do |
|
|
//not accept this License. Therefore, by modifying or propagating a |
|
|
//covered work, you indicate your acceptance of this License to do so. |
|
|
// |
|
|
// 10. Automatic Licensing of Downstream Recipients. |
|
|
// |
|
|
// Each time you convey a covered work, the recipient automatically |
|
|
//receives a license from the original licensors, to run, modify and |
|
|
//propagate that work, subject to this License. You are not responsible |
|
|
//for enforcing compliance by third parties with this License. |
|
|
// |
|
|
// An "entity transaction" is a transaction transferring control of an |
|
|
//organization, or substantially all assets of one, or subdividing an |
|
|
//organization, or merging organizations. If propagation of a covered |
|
|
//work results from an entity transaction, each party to that |
|
|
//transaction who receives a copy of the work also receives whatever |
|
|
//licenses to the work the party's predecessor in interest had or could |
|
|
//give under the previous paragraph, plus a right to possession of the |
|
|
//Corresponding Source of the work from the predecessor in interest, if |
|
|
//the predecessor has it or can get it with reasonable efforts. |
|
|
// |
|
|
// You may not impose any further restrictions on the exercise of the |
|
|
//rights granted or affirmed under this License. For example, you may |
|
|
//not impose a license fee, royalty, or other charge for exercise of |
|
|
//rights granted under this License, and you may not initiate litigation |
|
|
//(including a cross-claim or counterclaim in a lawsuit) alleging that |
|
|
//any patent claim is infringed by making, using, selling, offering for |
|
|
//sale, or importing the Program or any portion of it. |
|
|
// |
|
|
// 11. Patents. |
|
|
// |
|
|
// A "contributor" is a copyright holder who authorizes use under this |
|
|
//License of the Program or a work on which the Program is based. The |
|
|
//work thus licensed is called the contributor's "contributor version". |
|
|
// |
|
|
// A contributor's "essential patent claims" are all patent claims |
|
|
//owned or controlled by the contributor, whether already acquired or |
|
|
//hereafter acquired, that would be infringed by some manner, permitted |
|
|
//by this License, of making, using, or selling its contributor version, |
|
|
//but do not include claims that would be infringed only as a |
|
|
//consequence of further modification of the contributor version. For |
|
|
//purposes of this definition, "control" includes the right to grant |
|
|
//patent sublicenses in a manner consistent with the requirements of |
|
|
//this License. |
|
|
// |
|
|
// Each contributor grants you a non-exclusive, worldwide, royalty-free |
|
|
//patent license under the contributor's essential patent claims, to |
|
|
//make, use, sell, offer for sale, import and otherwise run, modify and |
|
|
//propagate the contents of its contributor version. |
|
|
// |
|
|
// In the following three paragraphs, a "patent license" is any express |
|
|
//agreement or commitment, however denominated, not to enforce a patent |
|
|
//(such as an express permission to practice a patent or covenant not to |
|
|
//sue for patent infringement). To "grant" such a patent license to a |
|
|
//party means to make such an agreement or commitment not to enforce a |
|
|
//patent against the party. |
|
|
// |
|
|
// If you convey a covered work, knowingly relying on a patent license, |
|
|
//and the Corresponding Source of the work is not available for anyone |
|
|
//to copy, free of charge and under the terms of this License, through a |
|
|
//publicly available network server or other readily accessible means, |
|
|
//then you must either (1) cause the Corresponding Source to be so |
|
|
//available, or (2) arrange to deprive yourself of the benefit of the |
|
|
//patent license for this particular work, or (3) arrange, in a manner |
|
|
//consistent with the requirements of this License, to extend the patent |
|
|
//license to downstream recipients. "Knowingly relying" means you have |
|
|
//actual knowledge that, but for the patent license, your conveying the |
|
|
//covered work in a country, or your recipient's use of the covered work |
|
|
//in a country, would infringe one or more identifiable patents in that |
|
|
//country that you have reason to believe are valid. |
|
|
// |
|
|
// If, pursuant to or in connection with a single transaction or |
|
|
//arrangement, you convey, or propagate by procuring conveyance of, a |
|
|
//covered work, and grant a patent license to some of the parties |
|
|
//receiving the covered work authorizing them to use, propagate, modify |
|
|
//or convey a specific copy of the covered work, then the patent license |
|
|
//you grant is automatically extended to all recipients of the covered |
|
|
//work and works based on it. |
|
|
// |
|
|
// A patent license is "discriminatory" if it does not include within |
|
|
//the scope of its coverage, prohibits the exercise of, or is |
|
|
//conditioned on the non-exercise of one or more of the rights that are |
|
|
//specifically granted under this License. You may not convey a covered |
|
|
//work if you are a party to an arrangement with a third party that is |
|
|
//in the business of distributing software, under which you make payment |
|
|
//to the third party based on the extent of your activity of conveying |
|
|
//the work, and under which the third party grants, to any of the |
|
|
//parties who would receive the covered work from you, a discriminatory |
|
|
//patent license (a) in connection with copies of the covered work |
|
|
//conveyed by you (or copies made from those copies), or (b) primarily |
|
|
//for and in connection with specific products or compilations that |
|
|
//contain the covered work, unless you entered into that arrangement, |
|
|
//or that patent license was granted, prior to 28 March 2007. |
|
|
// |
|
|
// Nothing in this License shall be construed as excluding or limiting |
|
|
//any implied license or other defenses to infringement that may |
|
|
//otherwise be available to you under applicable patent law. |
|
|
// |
|
|
// 12. No Surrender of Others' Freedom. |
|
|
// |
|
|
// If conditions are imposed on you (whether by court order, agreement or |
|
|
//otherwise) that contradict the conditions of this License, they do not |
|
|
//excuse you from the conditions of this License. If you cannot convey a |
|
|
//covered work so as to satisfy simultaneously your obligations under this |
|
|
//License and any other pertinent obligations, then as a consequence you may |
|
|
//not convey it at all. For example, if you agree to terms that obligate you |
|
|
//to collect a royalty for further conveying from those to whom you convey |
|
|
//the Program, the only way you could satisfy both those terms and this |
|
|
//License would be to refrain entirely from conveying the Program. |
|
|
// |
|
|
// 13. Use with the GNU Affero General Public License. |
|
|
// |
|
|
// Notwithstanding any other provision of this License, you have |
|
|
//permission to link or combine any covered work with a work licensed |
|
|
//under version 3 of the GNU Affero General Public License into a single |
|
|
//combined work, and to convey the resulting work. The terms of this |
|
|
//License will continue to apply to the part which is the covered work, |
|
|
//but the special requirements of the GNU Affero General Public License, |
|
|
//section 13, concerning interaction through a network will apply to the |
|
|
//combination as such. |
|
|
// |
|
|
// 14. Revised Versions of this License. |
|
|
// |
|
|
// The Free Software Foundation may publish revised and/or new versions of |
|
|
//the GNU General Public License from time to time. Such new versions will |
|
|
//be similar in spirit to the present version, but may differ in detail to |
|
|
//address new problems or concerns. |
|
|
// |
|
|
// Each version is given a distinguishing version number. If the |
|
|
//Program specifies that a certain numbered version of the GNU General |
|
|
//Public License "or any later version" applies to it, you have the |
|
|
//option of following the terms and conditions either of that numbered |
|
|
//version or of any later version published by the Free Software |
|
|
//Foundation. If the Program does not specify a version number of the |
|
|
//GNU General Public License, you may choose any version ever published |
|
|
//by the Free Software Foundation. |
|
|
// |
|
|
// If the Program specifies that a proxy can decide which future |
|
|
//versions of the GNU General Public License can be used, that proxy's |
|
|
//public statement of acceptance of a version permanently authorizes you |
|
|
//to choose that version for the Program. |
|
|
// |
|
|
// Later license versions may give you additional or different |
|
|
//permissions. However, no additional obligations are imposed on any |
|
|
//author or copyright holder as a result of your choosing to follow a |
|
|
//later version. |
|
|
// |
|
|
// 15. Disclaimer of Warranty. |
|
|
// |
|
|
// THERE IS NO WARRANTY FOR THE PROGRAM, TO THE EXTENT PERMITTED BY |
|
|
//APPLICABLE LAW. EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT |
|
|
//HOLDERS AND/OR OTHER PARTIES PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY |
|
|
//OF ANY KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, |
|
|
//THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR |
|
|
//PURPOSE. THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE PROGRAM |
|
|
//IS WITH YOU. SHOULD THE PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF |
|
|
//ALL NECESSARY SERVICING, REPAIR OR CORRECTION. |

|
// How to Apply These Terms to Your New Programs |
|
|
// |
|
|
// If you develop a new program, and you want it to be of the greatest |
|
|
//possible use to the public, the best way to achieve this is to make it |
|
|
//free software which everyone can redistribute and change under these terms. |
|
|
// |
|
|
// To do so, attach the following notices to the program. It is safest |
|
|
//to attach them to the start of each source file to most effectively |
|
|
//state the exclusion of warranty; and each file should have at least |
|
|
//the "copyright" line and a pointer to where the full notice is found. |
|
|
// |
|
|
// <one line to give the program's name and a brief idea of what it does.> |

|
//This program, a PHP script, modifies all filenames in a directory to a canonical |
|
|
//form (no upper-case letters or unusual characters). This program is part of a |
|
|
//3-program suite designed to collectively create a web page directly from |
|
|
//digital camera files (and of course the web page can be customized by |
|
|
//hand-editing after it is automatically generated). The supported process for |
|
|
//creating a web page involves 3 programs (rather than 1) primarily to circumvent |
|
|
//the involuntary process termination that will occur in some shared environments |
|
|
//if a process consumes too much CPU time. |
|
|
// |
|
|
//The 3 programs in the 3-program suite are: |
|
|
// |
|
|
// filenames_canonize.php (this program): |
|
|
// Converts all names of files in a directory to lower-case, and makes |
|
|
// substitutions for any unusual characters. |
|
|
// |
|
|
// thumbnails_make.php: |
|
|
// Creates thumbnails from recognized image types. The thumbnails are |
|
|
// named relative to the original image file with the suffix "_small". |
|
|
// Only 20 files are converted on each invocation of the program, to |
|
|
// avoid the involuntary process termination that typically occurs in |
|
|
// a shared hosting environment when a process uses too much CPU time. |
|
|
// The program should be run repeatedly until it indicates that it has |
|
|
// no more thumbnails to create. |
|
|
// |
|
|
// If any full-sized photos are modified, any corresponding thumbnails |
|
|
// should be deleted and thumbnails_make.php and indexfile_make.php |
|
|
// should be run again. |
|
|
// |
|
|
// indexfile_make.php |
|
|
// Scans a directory and makes an index file ("index2.php") displaying |
|
|
// all the thumbnail images, each of which link to the corresponding |
|
|
// full-sized image. The index file is tailored to Dave Ashley's |
|
|
// needs, but the created file can be edited and most of the content |
|
|
// pasted into an HTML file. To avoid the accidental loss of |
|
|
// information, any existing "index2.php" file is renamed out of the |
|
|
// way. |
|
|
// |
|
|
//This script is designed to be run manually (rather than automatically invoked |
|
|
//as a result of a web page request). It was written in PHP for convenience |
|
|
//simply because DreamHost (the web hosting company Dave Ashley uses) has as part |
|
|
//of its hosting environment PHP with the ImageMagick library compiled in. |
|
|
// |
|
|
//Usually, this script is invoked using "php <path>/filenames_canonize.php", but |
|
|
//the method of invocation may vary based on computing platform details. |

// GNU GENERAL PUBLIC LICENSE |
|
|
// Version 3, 29 June 2007 |
|
|
// |
|
|
// Copyright (C) 2007 Free Software Foundation, Inc. <http://fsf.org/> |
|
|
// Everyone is permitted to copy and distribute verbatim copies |
|
|
// of this license document, but changing it is not allowed. |
|
|
// |
|
|
// Preamble |
|
|
// |
|
|
// The GNU General Public License is a free, copyleft license for |
|
|
// software and other kinds of works. |
|
|
// |
|
|
// The licenses for most software and other practical works are designed |
|
|
// to take away your freedom to share and change the works. By contrast, |
|
|
// the GNU General Public License is intended to guarantee your freedom to |
|
|
// share and change all versions of a program--to make sure it remains free |
|
|
// software for all its users. We, the Free Software Foundation, use the |
|
|
// GNU General Public License for most of our software; it applies also to |
|
|
// any other work released this way by its authors. You can apply it to |
|
|
// your programs, too. |
|
|
// |
|
|
// When we speak of free software, we are referring to freedom, not |
|
|
// price. Our General Public Licenses are designed to make sure that you |
|
|
// have the freedom to distribute copies of free software (and charge for |
|
|
// them if you wish), that you receive source code or can get it if you |
|
|
// want it, that you can change the software or use pieces of it in new |
|
|
// free programs, and that you know you can do these things. |
|
|
// |
|
|
// To protect your rights, we need to prevent others from denying you |
|
|
// these rights or asking you to surrender the rights. Therefore, you have |
|
|
// certain responsibilities if you distribute copies of the software, or if |
|
|
// you modify it: responsibilities to respect the freedom of others. |
|
|
// |
|
|
// For example, if you distribute copies of such a program, whether |
|
|
// gratis or for a fee, you must pass on to the recipients the same |
|
|
// freedoms that you received. You must make sure that they, too, receive |
|
|
// or can get the source code. And you must show them these terms so they |
|
|
// know their rights. |
|
|
// |
|
|
// Developers that use the GNU GPL protect your rights with two steps: |
|
|
// (1) assert copyright on the software, and (2) offer you this License |
|
|
// giving you legal permission to copy, distribute and/or modify it. |
|
|
// |
|
|
// For the developers' and authors' protection, the GPL clearly explains |
|
|
// that there is no warranty for this free software. For both users' and |
|
|
// authors' sake, the GPL requires that modified versions be marked as |
|
|
// changed, so that their problems will not be attributed erroneously to |
|
|
// authors of previous versions. |
|
|
// |
|
|
// Some devices are designed to deny users access to install or run |
|
|
// modified versions of the software inside them, although the manufacturer |
|
|
// can do so. This is fundamentally incompatible with the aim of |
|
|
// protecting users' freedom to change the software. The systematic |
|
|
// pattern of such abuse occurs in the area of products for individuals to |
|
|
// use, which is precisely where it is most unacceptable. Therefore, we |
|
|
// have designed this version of the GPL to prohibit the practice for those |
|
|
// products. If such problems arise substantially in other domains, we |
|
|
// stand ready to extend this provision to those domains in future versions |
|
|
// of the GPL, as needed to protect the freedom of users. |
|
|
// |
|
|
// Finally, every program is threatened constantly by software patents. |
|
|
// States should not allow patents to restrict development and use of |
|
|
// software on general-purpose computers, but in those that do, we wish to |
|
|
// avoid the special danger that patents applied to a free program could |
|
|
// make it effectively proprietary. To prevent this, the GPL assures that |
|
|
// patents cannot be used to render the program non-free. |
|
|
// |
|
|
// The precise terms and conditions for copying, distribution and |
|
|
// modification follow. |
|
|
// |
|
|
// TERMS AND CONDITIONS |
|
|
// |
|
|
// 0. Definitions. |
|
|
// |
|
|
// "This License" refers to version 3 of the GNU General Public License. |
|
|
// |
|
|
// "Copyright" also means copyright-like laws that apply to other kinds of |
|
|
// works, such as semiconductor masks. |
|
|
// |
|
|
// "The Program" refers to any copyrightable work licensed under this |
|
|
// License. Each licensee is addressed as "you". "Licensees" and |
|
|
// "recipients" may be individuals or organizations. |
|
|
// |
|
|
// To "modify" a work means to copy from or adapt all or part of the work |
|
|
// in a fashion requiring copyright permission, other than the making of an |
|
|
// exact copy. The resulting work is called a "modified version" of the |
|
|
// earlier work or a work "based on" the earlier work. |
|
|
// |
|
|
// A "covered work" means either the unmodified Program or a work based |
|
|
// on the Program. |
|
|
// |
|
|
// To "propagate" a work means to do anything with it that, without |
|
|
// permission, would make you directly or secondarily liable for |
|
|
// infringement under applicable copyright law, except executing it on a |
|
|
// computer or modifying a private copy. Propagation includes copying, |
|
|
// distribution (with or without modification), making available to the |
|
|
// public, and in some countries other activities as well. |
|
|
// |
|
|
// To "convey" a work means any kind of propagation that enables other |
|
|
// parties to make or receive copies. Mere interaction with a user through |
|
|
// a computer network, with no transfer of a copy, is not conveying. |
|
|
// |
|
|
// An interactive user interface displays "Appropriate Legal Notices" |
|
|
// to the extent that it includes a convenient and prominently visible |
|
|
// feature that (1) displays an appropriate copyright notice, and (2) |
|
|
// tells the user that there is no warranty for the work (except to the |
|
|
// extent that warranties are provided), that licensees may convey the |
|
|
// work under this License, and how to view a copy of this License. If |
|
|
// the interface presents a list of user commands or options, such as a |
|
|
// menu, a prominent item in the list meets this criterion. |
|
|
// |
|
|
// 1. Source Code. |
|
|
// |
|
|
// The "source code" for a work means the preferred form of the work |
|
|
// for making modifications to it. "Object code" means any non-source |
|
|
// form of a work. |
|
|
// |
|
|
// A "Standard Interface" means an interface that either is an official |
|
|
// standard defined by a recognized standards body, or, in the case of |
|
|
// interfaces specified for a particular programming language, one that |
|
|
// is widely used among developers working in that language. |
|
|
// |
|
|
// The "System Libraries" of an executable work include anything, other |
|
|
// than the work as a whole, that (a) is included in the normal form of |
|
|
// packaging a Major Component, but which is not part of that Major |
|
|
// Component, and (b) serves only to enable use of the work with that |
|
|
// Major Component, or to implement a Standard Interface for which an |
|
|
// implementation is available to the public in source code form. A |
|
|
// "Major Component", in this context, means a major essential component |
|
|
// (kernel, window system, and so on) of the specific operating system |
|
|
// (if any) on which the executable work runs, or a compiler used to |
|
|
// produce the work, or an object code interpreter used to run it. |
|
|
// |
|
|
// The "Corresponding Source" for a work in object code form means all |
|
|
// the source code needed to generate, install, and (for an executable |
|
|
// work) run the object code and to modify the work, including scripts to |
|
|
// control those activities. However, it does not include the work's |
|
|
// System Libraries, or general-purpose tools or generally available free |
|
|
// programs which are used unmodified in performing those activities but |
|
|
// which are not part of the work. For example, Corresponding Source |
|
|
// includes interface definition files associated with source files for |
|
|
// the work, and the source code for shared libraries and dynamically |
|
|
// linked subprograms that the work is specifically designed to require, |
|
|
// such as by intimate data communication or control flow between those |
|
|
// subprograms and other parts of the work. |
|
|
// |
|
|
// The Corresponding Source need not include anything that users |
|
|
// can regenerate automatically from other parts of the Corresponding |
|
|
// Source. |
|
|
// |
|
|
// The Corresponding Source for a work in source code form is that |
|
|
// same work. |
|
|
// |
|
|
// 2. Basic Permissions. |
|
|
// |
|
|
// All rights granted under this License are granted for the term of |
|
|
// copyright on the Program, and are irrevocable provided the stated |
|
|
// conditions are met. This License explicitly affirms your unlimited |
|
|
// permission to run the unmodified Program. The output from running a |
|
|
// covered work is covered by this License only if the output, given its |
|
|
// content, constitutes a covered work. This License acknowledges your |
|
|
// rights of fair use or other equivalent, as provided by copyright law. |
|
|
// |
|
|
// You may make, run and propagate covered works that you do not |
|
|
// convey, without conditions so long as your license otherwise remains |
|
|
// in force. You may convey covered works to others for the sole purpose |
|
|
// of having them make modifications exclusively for you, or provide you |
|
|
// with facilities for running those works, provided that you comply with |
|
|
// the terms of this License in conveying all material for which you do |
|
|
// not control copyright. Those thus making or running the covered works |
|
|
// for you must do so exclusively on your behalf, under your direction |
|
|
// and control, on terms that prohibit them from making any copies of |
|
|
// your copyrighted material outside their relationship with you. |
|
|
// |
|
|
// Conveying under any other circumstances is permitted solely under |
|
|
// the conditions stated below. Sublicensing is not allowed; section 10 |
|
|
// makes it unnecessary. |
|
|
// |
|
|
// 3. Protecting Users' Legal Rights From Anti-Circumvention Law. |
|
|
// |
|
|
// No covered work shall be deemed part of an effective technological |
|
|
// measure under any applicable law fulfilling obligations under article |
|
|
// 11 of the WIPO copyright treaty adopted on 20 December 1996, or |
|
|
// similar laws prohibiting or restricting circumvention of such |
|
|
// measures. |
|
|
// |
|
|
// When you convey a covered work, you waive any legal power to forbid |
|
|
// circumvention of technological measures to the extent such circumvention |
|
|
// is effected by exercising rights under this License with respect to |
|
|
// the covered work, and you disclaim any intention to limit operation or |
|
|
// modification of the work as a means of enforcing, against the work's |
|
|
// users, your or third parties' legal rights to forbid circumvention of |
|
|
// technological measures. |
|
|
// |
|
|
// 4. Conveying Verbatim Copies. |
|
|
// |
|
|
// You may convey verbatim copies of the Program's source code as you |
|
|
// receive it, in any medium, provided that you conspicuously and |
|
|
// appropriately publish on each copy an appropriate copyright notice; |
|
|
// keep intact all notices stating that this License and any |
|
|
// non-permissive terms added in accord with section 7 apply to the code; |
|
|
// keep intact all notices of the absence of any warranty; and give all |
|
|
// recipients a copy of this License along with the Program. |
|
|
// |
|
|
// You may charge any price or no price for each copy that you convey, |
|
|
// and you may offer support or warranty protection for a fee. |
|
|
// |
|
|
// 5. Conveying Modified Source Versions. |
|
|
// |
|
|
// You may convey a work based on the Program, or the modifications to |
|
|
// produce it from the Program, in the form of source code under the |
|
|
// terms of section 4, provided that you also meet all of these conditions: |
|
|
// |
|
|
// a) The work must carry prominent notices stating that you modified |
|
|
// it, and giving a relevant date. |
|
|
// |
|
|
// b) The work must carry prominent notices stating that it is |
|
|
// released under this License and any conditions added under section |
|
|
// 7. This requirement modifies the requirement in section 4 to |
|
|
// "keep intact all notices". |
|
|
// |
|
|
// c) You must license the entire work, as a whole, under this |
|
|
// License to anyone who comes into possession of a copy. This |
|
|
// License will therefore apply, along with any applicable section 7 |
|
|
// additional terms, to the whole of the work, and all its parts, |
|
|
// regardless of how they are packaged. This License gives no |
|
|
// permission to license the work in any other way, but it does not |
|
|
// invalidate such permission if you have separately received it. |
|
|
// |
|
|
// d) If the work has interactive user interfaces, each must display |
|
|
// Appropriate Legal Notices; however, if the Program has interactive |
|
|
// interfaces that do not display Appropriate Legal Notices, your |
|
|
// work need not make them do so. |
|
|
// |
|
|
// A compilation of a covered work with other separate and independent |
|
|
// works, which are not by their nature extensions of the covered work, |
|
|
// and which are not combined with it such as to form a larger program, |
|
|
// in or on a volume of a storage or distribution medium, is called an |
|
|
// "aggregate" if the compilation and its resulting copyright are not |
|
|
// used to limit the access or legal rights of the compilation's users |
|
|
// beyond what the individual works permit. Inclusion of a covered work |
|
|
// in an aggregate does not cause this License to apply to the other |
|
|
// parts of the aggregate. |
|
|
// |
|
|
// 6. Conveying Non-Source Forms. |
|
|
// |
|
|
// You may convey a covered work in object code form under the terms |
|
|
// of sections 4 and 5, provided that you also convey the |
|
|
// machine-readable Corresponding Source under the terms of this License, |
|
|
// in one of these ways: |
|
|
// |
|
|
// a) Convey the object code in, or embodied in, a physical product |
|
|
// (including a physical distribution medium), accompanied by the |
|
|
// Corresponding Source fixed on a durable physical medium |
|
|
// customarily used for software interchange. |
|
|
// |
|
|
// b) Convey the object code in, or embodied in, a physical product |
|
|
// (including a physical distribution medium), accompanied by a |
|
|
// written offer, valid for at least three years and valid for as |
|
|
// long as you offer spare parts or customer support for that product |
|
|
// model, to give anyone who possesses the object code either (1) a |
|
|
// copy of the Corresponding Source for all the software in the |
|
|
// product that is covered by this License, on a durable physical |
|
|
// medium customarily used for software interchange, for a price no |
|
|
// more than your reasonable cost of physically performing this |
|
|
// conveying of source, or (2) access to copy the |
|
|
// Corresponding Source from a network server at no charge. |
|
|
// |
|
|
// c) Convey individual copies of the object code with a copy of the |
|
|
// written offer to provide the Corresponding Source. This |
|
|
// alternative is allowed only occasionally and noncommercially, and |
|
|
// only if you received the object code with such an offer, in accord |
|
|
// with subsection 6b. |
|
|
// |
|
|
// d) Convey the object code by offering access from a designated |
|
|
// place (gratis or for a charge), and offer equivalent access to the |
|
|
// Corresponding Source in the same way through the same place at no |
|
|
// further charge. You need not require recipients to copy the |
|
|
// Corresponding Source along with the object code. If the place to |
|
|
// copy the object code is a network server, the Corresponding Source |
|
|
// may be on a different server (operated by you or a third party) |
|
|
// that supports equivalent copying facilities, provided you maintain |
|
|
// clear directions next to the object code saying where to find the |
|
|
// Corresponding Source. Regardless of what server hosts the |
|
|
// Corresponding Source, you remain obligated to ensure that it is |
|
|
// available for as long as needed to satisfy these requirements. |
|
|
// |
|
|
// e) Convey the object code using peer-to-peer transmission, provided |
|
|
// you inform other peers where the object code and Corresponding |
|
|
// Source of the work are being offered to the general public at no |
|
|
// charge under subsection 6d. |
|
|
// |
|
|
// A separable portion of the object code, whose source code is excluded |
|
|
// from the Corresponding Source as a System Library, need not be |
|
|
// included in conveying the object code work. |
|
|
// |
|
|
// A "User Product" is either (1) a "consumer product", which means any |
|
|
// tangible personal property which is normally used for personal, family, |
|
|
// or household purposes, or (2) anything designed or sold for incorporation |
|
|
// into a dwelling. In determining whether a product is a consumer product, |
|
|
// doubtful cases shall be resolved in favor of coverage. For a particular |
|
|
// product received by a particular user, "normally used" refers to a |
|
|
// typical or common use of that class of product, regardless of the status |
|
|
// of the particular user or of the way in which the particular user |
|
|
// actually uses, or expects or is expected to use, the product. A product |
|
|
// is a consumer product regardless of whether the product has substantial |
|
|
// commercial, industrial or non-consumer uses, unless such uses represent |
|
|
// the only significant mode of use of the product. |
|
|
// |
|
|
// "Installation Information" for a User Product means any methods, |
|
|
// procedures, authorization keys, or other information required to install |
|
|
// and execute modified versions of a covered work in that User Product from |
|
|
// a modified version of its Corresponding Source. The information must |
|
|
// suffice to ensure that the continued functioning of the modified object |
|
|
// code is in no case prevented or interfered with solely because |
|
|
// modification has been made. |
|
|
// |
|
|
// If you convey an object code work under this section in, or with, or |
|
|
// specifically for use in, a User Product, and the conveying occurs as |
|
|
// part of a transaction in which the right of possession and use of the |
|
|
// User Product is transferred to the recipient in perpetuity or for a |
|
|
// fixed term (regardless of how the transaction is characterized), the |
|
|
// Corresponding Source conveyed under this section must be accompanied |
|
|
// by the Installation Information. But this requirement does not apply |
|
|
// if neither you nor any third party retains the ability to install |
|
|
// modified object code on the User Product (for example, the work has |
|
|
// been installed in ROM). |
|
|
// |
|
|
// The requirement to provide Installation Information does not include a |
|
|
// requirement to continue to provide support service, warranty, or updates |
|
|
// for a work that has been modified or installed by the recipient, or for |
|
|
// the User Product in which it has been modified or installed. Access to a |
|
|
// network may be denied when the modification itself materially and |
|
|
// adversely affects the operation of the network or violates the rules and |
|
|
// protocols for communication across the network. |
|
|
// |
|
|
// Corresponding Source conveyed, and Installation Information provided, |
|
|
// in accord with this section must be in a format that is publicly |
|
|
// documented (and with an implementation available to the public in |
|
|
// source code form), and must require no special password or key for |
|
|
// unpacking, reading or copying. |
|
|
// |
|
|
// 7. Additional Terms. |
|
|
// |
|
|
// "Additional permissions" are terms that supplement the terms of this |
|
|
// License by making exceptions from one or more of its conditions. |
|
|
// Additional permissions that are applicable to the entire Program shall |
|
|
// be treated as though they were included in this License, to the extent |
|
|
// that they are valid under applicable law. If additional permissions |
|
|
// apply only to part of the Program, that part may be used separately |
|
|
// under those permissions, but the entire Program remains governed by |
|
|
// this License without regard to the additional permissions. |
|
|
// |
|
|
// When you convey a copy of a covered work, you may at your option |
|
|
// remove any additional permissions from that copy, or from any part of |
|
|
// it. (Additional permissions may be written to require their own |
|
|
// removal in certain cases when you modify the work.) You may place |
|
|
// additional permissions on material, added by you to a covered work, |
|
|
// for which you have or can give appropriate copyright permission. |
|
|
// |
|
|
// Notwithstanding any other provision of this License, for material you |
|
|
// add to a covered work, you may (if authorized by the copyright holders of |
|
|
// that material) supplement the terms of this License with terms: |
|
|
// |
|
|
// a) Disclaiming warranty or limiting liability differently from the |
|
|
// terms of sections 15 and 16 of this License; or |
|
|
// |
|
|
// b) Requiring preservation of specified reasonable legal notices or |
|
|
// author attributions in that material or in the Appropriate Legal |
|
|
// Notices displayed by works containing it; or |
|
|
// |
|
|
// c) Prohibiting misrepresentation of the origin of that material, or |
|
|
// requiring that modified versions of such material be marked in |
|
|
// reasonable ways as different from the original version; or |
|
|
// |
|
|
// d) Limiting the use for publicity purposes of names of licensors or |
|
|
// authors of the material; or |
|
|
// |
|
|
// e) Declining to grant rights under trademark law for use of some |
|
|
// trade names, trademarks, or service marks; or |
|
|
// |
|
|
// f) Requiring indemnification of licensors and authors of that |
|
|
// material by anyone who conveys the material (or modified versions of |
|
|
// it) with contractual assumptions of liability to the recipient, for |
|
|
// any liability that these contractual assumptions directly impose on |
|
|
// those licensors and authors. |
|
|
// |
|
|
// All other non-permissive additional terms are considered "further |
|
|
// restrictions" within the meaning of section 10. If the Program as you |
|
|
// received it, or any part of it, contains a notice stating that it is |
|
|
// governed by this License along with a term that is a further |
|
|
// restriction, you may remove that term. If a license document contains |
|
|
// a further restriction but permits relicensing or conveying under this |
|
|
// License, you may add to a covered work material governed by the terms |
|
|
// of that license document, provided that the further restriction does |
|
|
// not survive such relicensing or conveying. |
|
|
// |
|
|
// If you add terms to a covered work in accord with this section, you |
|
|
// must place, in the relevant source files, a statement of the |
|
|
// additional terms that apply to those files, or a notice indicating |
|
|
// where to find the applicable terms. |
|
|
// |
|
|
// Additional terms, permissive or non-permissive, may be stated in the |
|
|
// form of a separately written license, or stated as exceptions; |
|
|
// the above requirements apply either way. |
|
|
// |
|
|
// 8. Termination. |
|
|
// |
|
|
// You may not propagate or modify a covered work except as expressly |
|
|
// provided under this License. Any attempt otherwise to propagate or |
|
|
// modify it is void, and will automatically terminate your rights under |
|
|
// this License (including any patent licenses granted under the third |
|
|
// paragraph of section 11). |
|
|
// |
|
|
// However, if you cease all violation of this License, then your |
|
|
// license from a particular copyright holder is reinstated (a) |
|
|
// provisionally, unless and until the copyright holder explicitly and |
|
|
// finally terminates your license, and (b) permanently, if the copyright |
|
|
// holder fails to notify you of the violation by some reasonable means |
|
|
// prior to 60 days after the cessation. |
|
|
// |
|
|
// Moreover, your license from a particular copyright holder is |
|
|
// reinstated permanently if the copyright holder notifies you of the |
|
|
// violation by some reasonable means, this is the first time you have |
|
|
// received notice of violation of this License (for any work) from that |
|
|
// copyright holder, and you cure the violation prior to 30 days after |
|
|
// your receipt of the notice. |
|
|
// |
|
|
// Termination of your rights under this section does not terminate the |
|
|
// licenses of parties who have received copies or rights from you under |
|
|
// this License. If your rights have been terminated and not permanently |
|
|
// reinstated, you do not qualify to receive new licenses for the same |
|
|
// material under section 10. |
|
|
// |
|
|
// 9. Acceptance Not Required for Having Copies. |
|
|
// |
|
|
// You are not required to accept this License in order to receive or |
|
|
// run a copy of the Program. Ancillary propagation of a covered work |
|
|
// occurring solely as a consequence of using peer-to-peer transmission |
|
|
// to receive a copy likewise does not require acceptance. However, |
|
|
// nothing other than this License grants you permission to propagate or |
|
|
// modify any covered work. These actions infringe copyright if you do |
|
|
// not accept this License. Therefore, by modifying or propagating a |
|
|
// covered work, you indicate your acceptance of this License to do so. |
|
|
// |
|
|
// 10. Automatic Licensing of Downstream Recipients. |
|
|
// |
|
|
// Each time you convey a covered work, the recipient automatically |
|
|
// receives a license from the original licensors, to run, modify and |
|
|
// propagate that work, subject to this License. You are not responsible |
|
|
// for enforcing compliance by third parties with this License. |
|
|
// |
|
|
// An "entity transaction" is a transaction transferring control of an |
|
|
// organization, or substantially all assets of one, or subdividing an |
|
|
// organization, or merging organizations. If propagation of a covered |
|
|
// work results from an entity transaction, each party to that |
|
|
// transaction who receives a copy of the work also receives whatever |
|
|
// licenses to the work the party's predecessor in interest had or could |
|
|
// give under the previous paragraph, plus a right to possession of the |
|
|
// Corresponding Source of the work from the predecessor in interest, if |
|
|
// the predecessor has it or can get it with reasonable efforts. |
|
|
// |
|
|
// You may not impose any further restrictions on the exercise of the |
|
|
// rights granted or affirmed under this License. For example, you may |
|
|
// not impose a license fee, royalty, or other charge for exercise of |
|
|
// rights granted under this License, and you may not initiate litigation |
|
|
// (including a cross-claim or counterclaim in a lawsuit) alleging that |
|
|
// any patent claim is infringed by making, using, selling, offering for |
|
|
// sale, or importing the Program or any portion of it. |
|
|
// |
|
|
// 11. Patents. |
|
|
// |
|
|
// A "contributor" is a copyright holder who authorizes use under this |
|
|
// License of the Program or a work on which the Program is based. The |
|
|
// work thus licensed is called the contributor's "contributor version". |
|
|
// |
|
|
// A contributor's "essential patent claims" are all patent claims |
|
|
// owned or controlled by the contributor, whether already acquired or |
|
|
// hereafter acquired, that would be infringed by some manner, permitted |
|
|
// by this License, of making, using, or selling its contributor version, |
|
|
// but do not include claims that would be infringed only as a |
|
|
// consequence of further modification of the contributor version. For |
|
|
// purposes of this definition, "control" includes the right to grant |
|
|
// patent sublicenses in a manner consistent with the requirements of |
|
|
// this License. |
|
|
// |
|
|
// Each contributor grants you a non-exclusive, worldwide, royalty-free |
|
|
// patent license under the contributor's essential patent claims, to |
|
|
// make, use, sell, offer for sale, import and otherwise run, modify and |
|
|
// propagate the contents of its contributor version. |
|
|
// |
|
|
// In the following three paragraphs, a "patent license" is any express |
|
|
// agreement or commitment, however denominated, not to enforce a patent |
|
|
// (such as an express permission to practice a patent or covenant not to |
|
|
// sue for patent infringement). To "grant" such a patent license to a |
|
|
// party means to make such an agreement or commitment not to enforce a |
|
|
// patent against the party. |
|
|
// |
|
|
// If you convey a covered work, knowingly relying on a patent license, |
|
|
// and the Corresponding Source of the work is not available for anyone |
|
|
// to copy, free of charge and under the terms of this License, through a |
|
|
// publicly available network server or other readily accessible means, |
|
|
// then you must either (1) cause the Corresponding Source to be so |
|
|
// available, or (2) arrange to deprive yourself of the benefit of the |
|
|
// patent license for this particular work, or (3) arrange, in a manner |
|
|
// consistent with the requirements of this License, to extend the patent |
|
|
// license to downstream recipients. "Knowingly relying" means you have |
|
|
// actual knowledge that, but for the patent license, your conveying the |
|
|
// covered work in a country, or your recipient's use of the covered work |
|
|
// in a country, would infringe one or more identifiable patents in that |
|
|
// country that you have reason to believe are valid. |
|
|
// |
|
|
// If, pursuant to or in connection with a single transaction or |
|
|
// arrangement, you convey, or propagate by procuring conveyance of, a |
|
|
// covered work, and grant a patent license to some of the parties |
|
|
// receiving the covered work authorizing them to use, propagate, modify |
|
|
// or convey a specific copy of the covered work, then the patent license |
|
|
// you grant is automatically extended to all recipients of the covered |
|
|
// work and works based on it. |
|
|
// |
|
|
// A patent license is "discriminatory" if it does not include within |
|
|
// the scope of its coverage, prohibits the exercise of, or is |
|
|
// conditioned on the non-exercise of one or more of the rights that are |
|
|
// specifically granted under this License. You may not convey a covered |
|
|
// work if you are a party to an arrangement with a third party that is |
|
|
// in the business of distributing software, under which you make payment |
|
|
// to the third party based on the extent of your activity of conveying |
|
|
// the work, and under which the third party grants, to any of the |
|
|
// parties who would receive the covered work from you, a discriminatory |
|
|
// patent license (a) in connection with copies of the covered work |
|
|
// conveyed by you (or copies made from those copies), or (b) primarily |
|
|
// for and in connection with specific products or compilations that |
|
|
// contain the covered work, unless you entered into that arrangement, |
|
|
// or that patent license was granted, prior to 28 March 2007. |
|
|
// |
|
|
// Nothing in this License shall be construed as excluding or limiting |
|
|
// any implied license or other defenses to infringement that may |
|
|
// otherwise be available to you under applicable patent law. |
|
|
// |
|
|
// 12. No Surrender of Others' Freedom. |
|
|
// |
|
|
// If conditions are imposed on you (whether by court order, agreement or |
|
|
// otherwise) that contradict the conditions of this License, they do not |
|
|
// excuse you from the conditions of this License. If you cannot convey a |
|
|
// covered work so as to satisfy simultaneously your obligations under this |
|
|
// License and any other pertinent obligations, then as a consequence you may |
|
|
// not convey it at all. For example, if you agree to terms that obligate you |
|
|
// to collect a royalty for further conveying from those to whom you convey |
|
|
// the Program, the only way you could satisfy both those terms and this |
|
|
// License would be to refrain entirely from conveying the Program. |
|
|
// |
|
|
// 13. Use with the GNU Affero General Public License. |
|
|
// |
|
|
// Notwithstanding any other provision of this License, you have |
|
|
// permission to link or combine any covered work with a work licensed |
|
|
// under version 3 of the GNU Affero General Public License into a single |
|
|
// combined work, and to convey the resulting work. The terms of this |
|
|
// License will continue to apply to the part which is the covered work, |
|
|
// but the special requirements of the GNU Affero General Public License, |
|
|
// section 13, concerning interaction through a network will apply to the |
|
|
// combination as such. |
|
|
// |
|
|
// 14. Revised Versions of this License. |
|
|
// |
|
|
// The Free Software Foundation may publish revised and/or new versions of |
|
|
// the GNU General Public License from time to time. Such new versions will |
|
|
// be similar in spirit to the present version, but may differ in detail to |
|
|
// address new problems or concerns. |
|
|
// |
|
|
// Each version is given a distinguishing version number. If the |
|
|
// Program specifies that a certain numbered version of the GNU General |
|
|
// Public License "or any later version" applies to it, you have the |
|
|
// option of following the terms and conditions either of that numbered |
|
|
// version or of any later version published by the Free Software |
|
|
// Foundation. If the Program does not specify a version number of the |
|
|
// GNU General Public License, you may choose any version ever published |
|
|
// by the Free Software Foundation. |
|
|
// |
|
|
// If the Program specifies that a proxy can decide which future |
|
|
// versions of the GNU General Public License can be used, that proxy's |
|
|
// public statement of acceptance of a version permanently authorizes you |
|
|
// to choose that version for the Program. |
|
|
// |
|
|
// Later license versions may give you additional or different |
|
|
// permissions. However, no additional obligations are imposed on any |
|
|
// author or copyright holder as a result of your choosing to follow a |
|
|
// later version. |
|
|
// |
|
|
// 15. Disclaimer of Warranty. |
|
|
// |
|
|
// THERE IS NO WARRANTY FOR THE PROGRAM, TO THE EXTENT PERMITTED BY |
|
|
// APPLICABLE LAW. EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT |
|
|
// HOLDERS AND/OR OTHER PARTIES PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY |
|
|
// OF ANY KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, |
|
|
// THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR |
|
|
// PURPOSE. THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE PROGRAM |
|
|
// IS WITH YOU. SHOULD THE PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF |
|
|
// ALL NECESSARY SERVICING, REPAIR OR CORRECTION. |
|
|
// |
|
|
// 16. Limitation of Liability. |
|
|
// |
|
|
// IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING |
|
|
// WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MODIFIES AND/OR CONVEYS |
|
|
// THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, INCLUDING ANY |
|
|
// GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING OUT OF THE |
|
|
// USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED TO LOSS OF |
|
|
// DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD |
|
|
// PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER PROGRAMS), |
|
|
// EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF |
|
|
// SUCH DAMAGES. |
|
|
// |
|
|
// 17. Interpretation of Sections 15 and 16. |
|
|
// |
|
|
// If the disclaimer of warranty and limitation of liability provided |
|
|
// above cannot be given local legal effect according to their terms, |
|
|
// reviewing courts shall apply local law that most closely approximates |
|
|
// an absolute waiver of all civil liability in connection with the |
|
|
// Program, unless a warranty or assumption of liability accompanies a |
|
|
// copy of the Program in return for a fee. |
