|  |                     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. | ||
|  | 
 | ||
|  |                      END OF TERMS AND CONDITIONS | ||
|  | 
 | ||
|  |             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.> | ||
|  |     Copyright (C) <year>  <name of author> | ||
|  | 
 | ||
|  |     This program is free software: you can redistribute it and/or modify | ||
|  |     it under the terms of the GNU General Public License as published by | ||
|  |     the Free Software Foundation, either version 3 of the License, or | ||
|  |     (at your option) any later version. | ||
|  | 
 | ||
|  |     This program is distributed in the hope that it will be useful, | ||
|  |     but WITHOUT ANY WARRANTY; without even the implied warranty of | ||
|  |     MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.  See the | ||
|  |     GNU General Public License for more details. | ||
|  | 
 | ||
|  |     You should have received a copy of the GNU General Public License | ||
|  |     along with this program.  If not, see <http://www.gnu.org/licenses/>. | ||
|  | 
 | ||
|  | Also add information on how to contact you by electronic and paper mail. | ||
|  | 
 | ||
|  |   If the program does terminal interaction, make it output a short | ||
|  | notice like this when it starts in an interactive mode: | ||
|  | 
 | ||
|  |     <program>  Copyright (C) <year>  <name of author> | ||
|  |     This program comes with ABSOLUTELY NO WARRANTY; for details type `show w'. | ||
|  |     This is free software, and you are welcome to redistribute it | ||
|  |     under certain conditions; type `show c' for details. | ||
|  | 
 | ||
|  | The hypothetical commands `show w' and `show c' should show the appropriate | ||
|  | parts of the General Public License.  Of course, your program's commands | ||
|  | might be different; for a GUI interface, you would use an "about box". | ||
|  | 
 | ||
|  |   You should also get your employer (if you work as a programmer) or school, | ||
|  | if any, to sign a "copyright disclaimer" for the program, if necessary. | ||
|  | For more information on this, and how to apply and follow the GNU GPL, see | ||

|  | 
 | ||
|  |   The GNU General Public License does not permit incorporating your program | ||
|  | into proprietary programs.  If your program is a subroutine library, you | ||
|  | may consider it more useful to permit linking proprietary applications with | ||
|  | the library.  If this is what you want to do, use the GNU Lesser General | ||
|  | Public License instead of this License.  But first, please read | ||
