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

Of course, your program's commands franta-hg@0: might be different; for a GUI interface, you would use an ``about box''. franta-hg@0: franta-hg@0: You should also get your employer (if you work as a programmer) or franta-hg@0: school, if any, to sign a ``copyright disclaimer'' for the program, if franta-hg@0: necessary. For more information on this, and how to apply and follow franta-hg@0: the GNU GPL, see \texttt{http://www.gnu.org/licenses/}. franta-hg@0: franta-hg@0: The GNU General Public License does not permit incorporating your franta-hg@0: program into proprietary programs. If your program is a subroutine franta-hg@0: library, you may consider it more useful to permit linking proprietary franta-hg@0: applications with the library. If this is what you want to do, use franta-hg@0: the GNU Lesser General Public License instead of this License.
