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