rrenkert@410: GNU GENERAL PUBLIC LICENSE
rrenkert@410: Version 3, 29 June 2007
rrenkert@410:
rrenkert@410: Copyright (C) 2007 Free Software Foundation, Inc.
rrenkert@410: Everyone is permitted to copy and distribute verbatim copies
rrenkert@410: of this license document, but changing it is not allowed.
rrenkert@410:
rrenkert@410: Preamble
rrenkert@410:
rrenkert@410: The GNU General Public License is a free, copyleft license for
rrenkert@410: software and other kinds of works.
rrenkert@410:
rrenkert@410: The licenses for most software and other practical works are designed
rrenkert@410: to take away your freedom to share and change the works. By contrast,
rrenkert@410: the GNU General Public License is intended to guarantee your freedom to
rrenkert@410: share and change all versions of a program--to make sure it remains free
rrenkert@410: software for all its users. We, the Free Software Foundation, use the
rrenkert@410: GNU General Public License for most of our software; it applies also to
rrenkert@410: any other work released this way by its authors. You can apply it to
rrenkert@410: your programs, too.
rrenkert@410:
rrenkert@410: When we speak of free software, we are referring to freedom, not
rrenkert@410: price. Our General Public Licenses are designed to make sure that you
rrenkert@410: have the freedom to distribute copies of free software (and charge for
rrenkert@410: them if you wish), that you receive source code or can get it if you
rrenkert@410: want it, that you can change the software or use pieces of it in new
rrenkert@410: free programs, and that you know you can do these things.
rrenkert@410:
rrenkert@410: To protect your rights, we need to prevent others from denying you
rrenkert@410: these rights or asking you to surrender the rights. Therefore, you have
rrenkert@410: certain responsibilities if you distribute copies of the software, or if
rrenkert@410: you modify it: responsibilities to respect the freedom of others.
rrenkert@410:
rrenkert@410: For example, if you distribute copies of such a program, whether
rrenkert@410: gratis or for a fee, you must pass on to the recipients the same
rrenkert@410: freedoms that you received. You must make sure that they, too, receive
rrenkert@410: or can get the source code. And you must show them these terms so they
rrenkert@410: know their rights.
rrenkert@410:
rrenkert@410: Developers that use the GNU GPL protect your rights with two steps:
rrenkert@410: (1) assert copyright on the software, and (2) offer you this License
rrenkert@410: giving you legal permission to copy, distribute and/or modify it.
rrenkert@410:
rrenkert@410: For the developers' and authors' protection, the GPL clearly explains
rrenkert@410: that there is no warranty for this free software. For both users' and
rrenkert@410: authors' sake, the GPL requires that modified versions be marked as
rrenkert@410: changed, so that their problems will not be attributed erroneously to
rrenkert@410: authors of previous versions.
rrenkert@410:
rrenkert@410: Some devices are designed to deny users access to install or run
rrenkert@410: modified versions of the software inside them, although the manufacturer
rrenkert@410: can do so. This is fundamentally incompatible with the aim of
rrenkert@410: protecting users' freedom to change the software. The systematic
rrenkert@410: pattern of such abuse occurs in the area of products for individuals to
rrenkert@410: use, which is precisely where it is most unacceptable. Therefore, we
rrenkert@410: have designed this version of the GPL to prohibit the practice for those
rrenkert@410: products. If such problems arise substantially in other domains, we
rrenkert@410: stand ready to extend this provision to those domains in future versions
rrenkert@410: of the GPL, as needed to protect the freedom of users.
rrenkert@410:
rrenkert@410: Finally, every program is threatened constantly by software patents.
rrenkert@410: States should not allow patents to restrict development and use of
rrenkert@410: software on general-purpose computers, but in those that do, we wish to
rrenkert@410: avoid the special danger that patents applied to a free program could
rrenkert@410: make it effectively proprietary. To prevent this, the GPL assures that
rrenkert@410: patents cannot be used to render the program non-free.
rrenkert@410:
rrenkert@410: The precise terms and conditions for copying, distribution and
rrenkert@410: modification follow.
rrenkert@410:
rrenkert@410: TERMS AND CONDITIONS
rrenkert@410:
rrenkert@410: 0. Definitions.
rrenkert@410:
rrenkert@410: "This License" refers to version 3 of the GNU General Public License.
rrenkert@410:
rrenkert@410: "Copyright" also means copyright-like laws that apply to other kinds of
rrenkert@410: works, such as semiconductor masks.
rrenkert@410:
rrenkert@410: "The Program" refers to any copyrightable work licensed under this
rrenkert@410: License. Each licensee is addressed as "you". "Licensees" and
rrenkert@410: "recipients" may be individuals or organizations.
rrenkert@410:
rrenkert@410: To "modify" a work means to copy from or adapt all or part of the work
rrenkert@410: in a fashion requiring copyright permission, other than the making of an
rrenkert@410: exact copy. The resulting work is called a "modified version" of the
rrenkert@410: earlier work or a work "based on" the earlier work.
rrenkert@410:
rrenkert@410: A "covered work" means either the unmodified Program or a work based
rrenkert@410: on the Program.
rrenkert@410:
rrenkert@410: To "propagate" a work means to do anything with it that, without
rrenkert@410: permission, would make you directly or secondarily liable for
rrenkert@410: infringement under applicable copyright law, except executing it on a
rrenkert@410: computer or modifying a private copy. Propagation includes copying,
rrenkert@410: distribution (with or without modification), making available to the
rrenkert@410: public, and in some countries other activities as well.
rrenkert@410:
rrenkert@410: To "convey" a work means any kind of propagation that enables other
rrenkert@410: parties to make or receive copies. Mere interaction with a user through
rrenkert@410: a computer network, with no transfer of a copy, is not conveying.
rrenkert@410:
rrenkert@410: An interactive user interface displays "Appropriate Legal Notices"
rrenkert@410: to the extent that it includes a convenient and prominently visible
rrenkert@410: feature that (1) displays an appropriate copyright notice, and (2)
rrenkert@410: tells the user that there is no warranty for the work (except to the
rrenkert@410: extent that warranties are provided), that licensees may convey the
rrenkert@410: work under this License, and how to view a copy of this License. If
rrenkert@410: the interface presents a list of user commands or options, such as a
rrenkert@410: menu, a prominent item in the list meets this criterion.
rrenkert@410:
rrenkert@410: 1. Source Code.
rrenkert@410:
rrenkert@410: The "source code" for a work means the preferred form of the work
rrenkert@410: for making modifications to it. "Object code" means any non-source
rrenkert@410: form of a work.
rrenkert@410:
rrenkert@410: A "Standard Interface" means an interface that either is an official
rrenkert@410: standard defined by a recognized standards body, or, in the case of
rrenkert@410: interfaces specified for a particular programming language, one that
rrenkert@410: is widely used among developers working in that language.
rrenkert@410:
rrenkert@410: The "System Libraries" of an executable work include anything, other
rrenkert@410: than the work as a whole, that (a) is included in the normal form of
rrenkert@410: packaging a Major Component, but which is not part of that Major
rrenkert@410: Component, and (b) serves only to enable use of the work with that
rrenkert@410: Major Component, or to implement a Standard Interface for which an
rrenkert@410: implementation is available to the public in source code form. A
rrenkert@410: "Major Component", in this context, means a major essential component
rrenkert@410: (kernel, window system, and so on) of the specific operating system
rrenkert@410: (if any) on which the executable work runs, or a compiler used to
rrenkert@410: produce the work, or an object code interpreter used to run it.
rrenkert@410:
rrenkert@410: The "Corresponding Source" for a work in object code form means all
rrenkert@410: the source code needed to generate, install, and (for an executable
rrenkert@410: work) run the object code and to modify the work, including scripts to
rrenkert@410: control those activities. However, it does not include the work's
rrenkert@410: System Libraries, or general-purpose tools or generally available free
rrenkert@410: programs which are used unmodified in performing those activities but
rrenkert@410: which are not part of the work. For example, Corresponding Source
rrenkert@410: includes interface definition files associated with source files for
rrenkert@410: the work, and the source code for shared libraries and dynamically
rrenkert@410: linked subprograms that the work is specifically designed to require,
rrenkert@410: such as by intimate data communication or control flow between those
rrenkert@410: subprograms and other parts of the work.
rrenkert@410:
rrenkert@410: The Corresponding Source need not include anything that users
rrenkert@410: can regenerate automatically from other parts of the Corresponding
rrenkert@410: Source.
rrenkert@410:
rrenkert@410: The Corresponding Source for a work in source code form is that
rrenkert@410: same work.
rrenkert@410:
rrenkert@410: 2. Basic Permissions.
rrenkert@410:
rrenkert@410: All rights granted under this License are granted for the term of
rrenkert@410: copyright on the Program, and are irrevocable provided the stated
rrenkert@410: conditions are met. This License explicitly affirms your unlimited
rrenkert@410: permission to run the unmodified Program. The output from running a
rrenkert@410: covered work is covered by this License only if the output, given its
rrenkert@410: content, constitutes a covered work. This License acknowledges your
rrenkert@410: rights of fair use or other equivalent, as provided by copyright law.
rrenkert@410:
rrenkert@410: You may make, run and propagate covered works that you do not
rrenkert@410: convey, without conditions so long as your license otherwise remains
rrenkert@410: in force. You may convey covered works to others for the sole purpose
rrenkert@410: of having them make modifications exclusively for you, or provide you
rrenkert@410: with facilities for running those works, provided that you comply with
rrenkert@410: the terms of this License in conveying all material for which you do
rrenkert@410: not control copyright. Those thus making or running the covered works
rrenkert@410: for you must do so exclusively on your behalf, under your direction
rrenkert@410: and control, on terms that prohibit them from making any copies of
rrenkert@410: your copyrighted material outside their relationship with you.
rrenkert@410:
rrenkert@410: Conveying under any other circumstances is permitted solely under
rrenkert@410: the conditions stated below. Sublicensing is not allowed; section 10
rrenkert@410: makes it unnecessary.
rrenkert@410:
rrenkert@410: 3. Protecting Users' Legal Rights From Anti-Circumvention Law.
rrenkert@410:
rrenkert@410: No covered work shall be deemed part of an effective technological
rrenkert@410: measure under any applicable law fulfilling obligations under article
rrenkert@410: 11 of the WIPO copyright treaty adopted on 20 December 1996, or
rrenkert@410: similar laws prohibiting or restricting circumvention of such
rrenkert@410: measures.
rrenkert@410:
rrenkert@410: When you convey a covered work, you waive any legal power to forbid
rrenkert@410: circumvention of technological measures to the extent such circumvention
rrenkert@410: is effected by exercising rights under this License with respect to
rrenkert@410: the covered work, and you disclaim any intention to limit operation or
rrenkert@410: modification of the work as a means of enforcing, against the work's
rrenkert@410: users, your or third parties' legal rights to forbid circumvention of
rrenkert@410: technological measures.
rrenkert@410:
rrenkert@410: 4. Conveying Verbatim Copies.
rrenkert@410:
rrenkert@410: You may convey verbatim copies of the Program's source code as you
rrenkert@410: receive it, in any medium, provided that you conspicuously and
rrenkert@410: appropriately publish on each copy an appropriate copyright notice;
rrenkert@410: keep intact all notices stating that this License and any
rrenkert@410: non-permissive terms added in accord with section 7 apply to the code;
rrenkert@410: keep intact all notices of the absence of any warranty; and give all
rrenkert@410: recipients a copy of this License along with the Program.
rrenkert@410:
rrenkert@410: You may charge any price or no price for each copy that you convey,
rrenkert@410: and you may offer support or warranty protection for a fee.
rrenkert@410:
rrenkert@410: 5. Conveying Modified Source Versions.
rrenkert@410:
rrenkert@410: You may convey a work based on the Program, or the modifications to
rrenkert@410: produce it from the Program, in the form of source code under the
rrenkert@410: terms of section 4, provided that you also meet all of these conditions:
rrenkert@410:
rrenkert@410: a) The work must carry prominent notices stating that you modified
rrenkert@410: it, and giving a relevant date.
rrenkert@410:
rrenkert@410: b) The work must carry prominent notices stating that it is
rrenkert@410: released under this License and any conditions added under section
rrenkert@410: 7. This requirement modifies the requirement in section 4 to
rrenkert@410: "keep intact all notices".
rrenkert@410:
rrenkert@410: c) You must license the entire work, as a whole, under this
rrenkert@410: License to anyone who comes into possession of a copy. This
rrenkert@410: License will therefore apply, along with any applicable section 7
rrenkert@410: additional terms, to the whole of the work, and all its parts,
rrenkert@410: regardless of how they are packaged. This License gives no
rrenkert@410: permission to license the work in any other way, but it does not
rrenkert@410: invalidate such permission if you have separately received it.
rrenkert@410:
rrenkert@410: d) If the work has interactive user interfaces, each must display
rrenkert@410: Appropriate Legal Notices; however, if the Program has interactive
rrenkert@410: interfaces that do not display Appropriate Legal Notices, your
rrenkert@410: work need not make them do so.
rrenkert@410:
rrenkert@410: A compilation of a covered work with other separate and independent
rrenkert@410: works, which are not by their nature extensions of the covered work,
rrenkert@410: and which are not combined with it such as to form a larger program,
rrenkert@410: in or on a volume of a storage or distribution medium, is called an
rrenkert@410: "aggregate" if the compilation and its resulting copyright are not
rrenkert@410: used to limit the access or legal rights of the compilation's users
rrenkert@410: beyond what the individual works permit. Inclusion of a covered work
rrenkert@410: in an aggregate does not cause this License to apply to the other
rrenkert@410: parts of the aggregate.
rrenkert@410:
rrenkert@410: 6. Conveying Non-Source Forms.
rrenkert@410:
rrenkert@410: You may convey a covered work in object code form under the terms
rrenkert@410: of sections 4 and 5, provided that you also convey the
rrenkert@410: machine-readable Corresponding Source under the terms of this License,
rrenkert@410: in one of these ways:
rrenkert@410:
rrenkert@410: a) Convey the object code in, or embodied in, a physical product
rrenkert@410: (including a physical distribution medium), accompanied by the
rrenkert@410: Corresponding Source fixed on a durable physical medium
rrenkert@410: customarily used for software interchange.
rrenkert@410:
rrenkert@410: b) Convey the object code in, or embodied in, a physical product
rrenkert@410: (including a physical distribution medium), accompanied by a
rrenkert@410: written offer, valid for at least three years and valid for as
rrenkert@410: long as you offer spare parts or customer support for that product
rrenkert@410: model, to give anyone who possesses the object code either (1) a
rrenkert@410: copy of the Corresponding Source for all the software in the
rrenkert@410: product that is covered by this License, on a durable physical
rrenkert@410: medium customarily used for software interchange, for a price no
rrenkert@410: more than your reasonable cost of physically performing this
rrenkert@410: conveying of source, or (2) access to copy the
rrenkert@410: Corresponding Source from a network server at no charge.
rrenkert@410:
rrenkert@410: c) Convey individual copies of the object code with a copy of the
rrenkert@410: written offer to provide the Corresponding Source. This
rrenkert@410: alternative is allowed only occasionally and noncommercially, and
rrenkert@410: only if you received the object code with such an offer, in accord
rrenkert@410: with subsection 6b.
rrenkert@410:
rrenkert@410: d) Convey the object code by offering access from a designated
rrenkert@410: place (gratis or for a charge), and offer equivalent access to the
rrenkert@410: Corresponding Source in the same way through the same place at no
rrenkert@410: further charge. You need not require recipients to copy the
rrenkert@410: Corresponding Source along with the object code. If the place to
rrenkert@410: copy the object code is a network server, the Corresponding Source
rrenkert@410: may be on a different server (operated by you or a third party)
rrenkert@410: that supports equivalent copying facilities, provided you maintain
rrenkert@410: clear directions next to the object code saying where to find the
rrenkert@410: Corresponding Source. Regardless of what server hosts the
rrenkert@410: Corresponding Source, you remain obligated to ensure that it is
rrenkert@410: available for as long as needed to satisfy these requirements.
rrenkert@410:
rrenkert@410: e) Convey the object code using peer-to-peer transmission, provided
rrenkert@410: you inform other peers where the object code and Corresponding
rrenkert@410: Source of the work are being offered to the general public at no
rrenkert@410: charge under subsection 6d.
rrenkert@410:
rrenkert@410: A separable portion of the object code, whose source code is excluded
rrenkert@410: from the Corresponding Source as a System Library, need not be
rrenkert@410: included in conveying the object code work.
rrenkert@410:
rrenkert@410: A "User Product" is either (1) a "consumer product", which means any
rrenkert@410: tangible personal property which is normally used for personal, family,
rrenkert@410: or household purposes, or (2) anything designed or sold for incorporation
rrenkert@410: into a dwelling. In determining whether a product is a consumer product,
rrenkert@410: doubtful cases shall be resolved in favor of coverage. For a particular
rrenkert@410: product received by a particular user, "normally used" refers to a
rrenkert@410: typical or common use of that class of product, regardless of the status
rrenkert@410: of the particular user or of the way in which the particular user
rrenkert@410: actually uses, or expects or is expected to use, the product. A product
rrenkert@410: is a consumer product regardless of whether the product has substantial
rrenkert@410: commercial, industrial or non-consumer uses, unless such uses represent
rrenkert@410: the only significant mode of use of the product.
rrenkert@410:
rrenkert@410: "Installation Information" for a User Product means any methods,
rrenkert@410: procedures, authorization keys, or other information required to install
rrenkert@410: and execute modified versions of a covered work in that User Product from
rrenkert@410: a modified version of its Corresponding Source. The information must
rrenkert@410: suffice to ensure that the continued functioning of the modified object
rrenkert@410: code is in no case prevented or interfered with solely because
rrenkert@410: modification has been made.
rrenkert@410:
rrenkert@410: If you convey an object code work under this section in, or with, or
rrenkert@410: specifically for use in, a User Product, and the conveying occurs as
rrenkert@410: part of a transaction in which the right of possession and use of the
rrenkert@410: User Product is transferred to the recipient in perpetuity or for a
rrenkert@410: fixed term (regardless of how the transaction is characterized), the
rrenkert@410: Corresponding Source conveyed under this section must be accompanied
rrenkert@410: by the Installation Information. But this requirement does not apply
rrenkert@410: if neither you nor any third party retains the ability to install
rrenkert@410: modified object code on the User Product (for example, the work has
rrenkert@410: been installed in ROM).
rrenkert@410:
rrenkert@410: The requirement to provide Installation Information does not include a
rrenkert@410: requirement to continue to provide support service, warranty, or updates
rrenkert@410: for a work that has been modified or installed by the recipient, or for
rrenkert@410: the User Product in which it has been modified or installed. Access to a
rrenkert@410: network may be denied when the modification itself materially and
rrenkert@410: adversely affects the operation of the network or violates the rules and
rrenkert@410: protocols for communication across the network.
rrenkert@410:
rrenkert@410: Corresponding Source conveyed, and Installation Information provided,
rrenkert@410: in accord with this section must be in a format that is publicly
rrenkert@410: documented (and with an implementation available to the public in
rrenkert@410: source code form), and must require no special password or key for
rrenkert@410: unpacking, reading or copying.
rrenkert@410:
rrenkert@410: 7. Additional Terms.
rrenkert@410:
rrenkert@410: "Additional permissions" are terms that supplement the terms of this
rrenkert@410: License by making exceptions from one or more of its conditions.
rrenkert@410: Additional permissions that are applicable to the entire Program shall
rrenkert@410: be treated as though they were included in this License, to the extent
rrenkert@410: that they are valid under applicable law. If additional permissions
rrenkert@410: apply only to part of the Program, that part may be used separately
rrenkert@410: under those permissions, but the entire Program remains governed by
rrenkert@410: this License without regard to the additional permissions.
rrenkert@410:
rrenkert@410: When you convey a copy of a covered work, you may at your option
rrenkert@410: remove any additional permissions from that copy, or from any part of
rrenkert@410: it. (Additional permissions may be written to require their own
rrenkert@410: removal in certain cases when you modify the work.) You may place
rrenkert@410: additional permissions on material, added by you to a covered work,
rrenkert@410: for which you have or can give appropriate copyright permission.
rrenkert@410:
rrenkert@410: Notwithstanding any other provision of this License, for material you
rrenkert@410: add to a covered work, you may (if authorized by the copyright holders of
rrenkert@410: that material) supplement the terms of this License with terms:
rrenkert@410:
rrenkert@410: a) Disclaiming warranty or limiting liability differently from the
rrenkert@410: terms of sections 15 and 16 of this License; or
rrenkert@410:
rrenkert@410: b) Requiring preservation of specified reasonable legal notices or
rrenkert@410: author attributions in that material or in the Appropriate Legal
rrenkert@410: Notices displayed by works containing it; or
rrenkert@410:
rrenkert@410: c) Prohibiting misrepresentation of the origin of that material, or
rrenkert@410: requiring that modified versions of such material be marked in
rrenkert@410: reasonable ways as different from the original version; or
rrenkert@410:
rrenkert@410: d) Limiting the use for publicity purposes of names of licensors or
rrenkert@410: authors of the material; or
rrenkert@410:
rrenkert@410: e) Declining to grant rights under trademark law for use of some
rrenkert@410: trade names, trademarks, or service marks; or
rrenkert@410:
rrenkert@410: f) Requiring indemnification of licensors and authors of that
rrenkert@410: material by anyone who conveys the material (or modified versions of
rrenkert@410: it) with contractual assumptions of liability to the recipient, for
rrenkert@410: any liability that these contractual assumptions directly impose on
rrenkert@410: those licensors and authors.
rrenkert@410:
rrenkert@410: All other non-permissive additional terms are considered "further
rrenkert@410: restrictions" within the meaning of section 10. If the Program as you
rrenkert@410: received it, or any part of it, contains a notice stating that it is
rrenkert@410: governed by this License along with a term that is a further
rrenkert@410: restriction, you may remove that term. If a license document contains
rrenkert@410: a further restriction but permits relicensing or conveying under this
rrenkert@410: License, you may add to a covered work material governed by the terms
rrenkert@410: of that license document, provided that the further restriction does
rrenkert@410: not survive such relicensing or conveying.
rrenkert@410:
rrenkert@410: If you add terms to a covered work in accord with this section, you
rrenkert@410: must place, in the relevant source files, a statement of the
rrenkert@410: additional terms that apply to those files, or a notice indicating
rrenkert@410: where to find the applicable terms.
rrenkert@410:
rrenkert@410: Additional terms, permissive or non-permissive, may be stated in the
rrenkert@410: form of a separately written license, or stated as exceptions;
rrenkert@410: the above requirements apply either way.
rrenkert@410:
rrenkert@410: 8. Termination.
rrenkert@410:
rrenkert@410: You may not propagate or modify a covered work except as expressly
rrenkert@410: provided under this License. Any attempt otherwise to propagate or
rrenkert@410: modify it is void, and will automatically terminate your rights under
rrenkert@410: this License (including any patent licenses granted under the third
rrenkert@410: paragraph of section 11).
rrenkert@410:
rrenkert@410: However, if you cease all violation of this License, then your
rrenkert@410: license from a particular copyright holder is reinstated (a)
rrenkert@410: provisionally, unless and until the copyright holder explicitly and
rrenkert@410: finally terminates your license, and (b) permanently, if the copyright
rrenkert@410: holder fails to notify you of the violation by some reasonable means
rrenkert@410: prior to 60 days after the cessation.
rrenkert@410:
rrenkert@410: Moreover, your license from a particular copyright holder is
rrenkert@410: reinstated permanently if the copyright holder notifies you of the
rrenkert@410: violation by some reasonable means, this is the first time you have
rrenkert@410: received notice of violation of this License (for any work) from that
rrenkert@410: copyright holder, and you cure the violation prior to 30 days after
rrenkert@410: your receipt of the notice.
rrenkert@410:
rrenkert@410: Termination of your rights under this section does not terminate the
rrenkert@410: licenses of parties who have received copies or rights from you under
rrenkert@410: this License. If your rights have been terminated and not permanently
rrenkert@410: reinstated, you do not qualify to receive new licenses for the same
rrenkert@410: material under section 10.
rrenkert@410:
rrenkert@410: 9. Acceptance Not Required for Having Copies.
rrenkert@410:
rrenkert@410: You are not required to accept this License in order to receive or
rrenkert@410: run a copy of the Program. Ancillary propagation of a covered work
rrenkert@410: occurring solely as a consequence of using peer-to-peer transmission
rrenkert@410: to receive a copy likewise does not require acceptance. However,
rrenkert@410: nothing other than this License grants you permission to propagate or
rrenkert@410: modify any covered work. These actions infringe copyright if you do
rrenkert@410: not accept this License. Therefore, by modifying or propagating a
rrenkert@410: covered work, you indicate your acceptance of this License to do so.
rrenkert@410:
rrenkert@410: 10. Automatic Licensing of Downstream Recipients.
rrenkert@410:
rrenkert@410: Each time you convey a covered work, the recipient automatically
rrenkert@410: receives a license from the original licensors, to run, modify and
rrenkert@410: propagate that work, subject to this License. You are not responsible
rrenkert@410: for enforcing compliance by third parties with this License.
rrenkert@410:
rrenkert@410: An "entity transaction" is a transaction transferring control of an
rrenkert@410: organization, or substantially all assets of one, or subdividing an
rrenkert@410: organization, or merging organizations. If propagation of a covered
rrenkert@410: work results from an entity transaction, each party to that
rrenkert@410: transaction who receives a copy of the work also receives whatever
rrenkert@410: licenses to the work the party's predecessor in interest had or could
rrenkert@410: give under the previous paragraph, plus a right to possession of the
rrenkert@410: Corresponding Source of the work from the predecessor in interest, if
rrenkert@410: the predecessor has it or can get it with reasonable efforts.
rrenkert@410:
rrenkert@410: You may not impose any further restrictions on the exercise of the
rrenkert@410: rights granted or affirmed under this License. For example, you may
rrenkert@410: not impose a license fee, royalty, or other charge for exercise of
rrenkert@410: rights granted under this License, and you may not initiate litigation
rrenkert@410: (including a cross-claim or counterclaim in a lawsuit) alleging that
rrenkert@410: any patent claim is infringed by making, using, selling, offering for
rrenkert@410: sale, or importing the Program or any portion of it.
rrenkert@410:
rrenkert@410: 11. Patents.
rrenkert@410:
rrenkert@410: A "contributor" is a copyright holder who authorizes use under this
rrenkert@410: License of the Program or a work on which the Program is based. The
rrenkert@410: work thus licensed is called the contributor's "contributor version".
rrenkert@410:
rrenkert@410: A contributor's "essential patent claims" are all patent claims
rrenkert@410: owned or controlled by the contributor, whether already acquired or
rrenkert@410: hereafter acquired, that would be infringed by some manner, permitted
rrenkert@410: by this License, of making, using, or selling its contributor version,
rrenkert@410: but do not include claims that would be infringed only as a
rrenkert@410: consequence of further modification of the contributor version. For
rrenkert@410: purposes of this definition, "control" includes the right to grant
rrenkert@410: patent sublicenses in a manner consistent with the requirements of
rrenkert@410: this License.
rrenkert@410:
rrenkert@410: Each contributor grants you a non-exclusive, worldwide, royalty-free
rrenkert@410: patent license under the contributor's essential patent claims, to
rrenkert@410: make, use, sell, offer for sale, import and otherwise run, modify and
rrenkert@410: propagate the contents of its contributor version.
rrenkert@410:
rrenkert@410: In the following three paragraphs, a "patent license" is any express
rrenkert@410: agreement or commitment, however denominated, not to enforce a patent
rrenkert@410: (such as an express permission to practice a patent or covenant not to
rrenkert@410: sue for patent infringement). To "grant" such a patent license to a
rrenkert@410: party means to make such an agreement or commitment not to enforce a
rrenkert@410: patent against the party.
rrenkert@410:
rrenkert@410: If you convey a covered work, knowingly relying on a patent license,
rrenkert@410: and the Corresponding Source of the work is not available for anyone
rrenkert@410: to copy, free of charge and under the terms of this License, through a
rrenkert@410: publicly available network server or other readily accessible means,
rrenkert@410: then you must either (1) cause the Corresponding Source to be so
rrenkert@410: available, or (2) arrange to deprive yourself of the benefit of the
rrenkert@410: patent license for this particular work, or (3) arrange, in a manner
rrenkert@410: consistent with the requirements of this License, to extend the patent
rrenkert@410: license to downstream recipients. "Knowingly relying" means you have
rrenkert@410: actual knowledge that, but for the patent license, your conveying the
rrenkert@410: covered work in a country, or your recipient's use of the covered work
rrenkert@410: in a country, would infringe one or more identifiable patents in that
rrenkert@410: country that you have reason to believe are valid.
rrenkert@410:
rrenkert@410: If, pursuant to or in connection with a single transaction or
rrenkert@410: arrangement, you convey, or propagate by procuring conveyance of, a
rrenkert@410: covered work, and grant a patent license to some of the parties
rrenkert@410: receiving the covered work authorizing them to use, propagate, modify
rrenkert@410: or convey a specific copy of the covered work, then the patent license
rrenkert@410: you grant is automatically extended to all recipients of the covered
rrenkert@410: work and works based on it.
rrenkert@410:
rrenkert@410: A patent license is "discriminatory" if it does not include within
rrenkert@410: the scope of its coverage, prohibits the exercise of, or is
rrenkert@410: conditioned on the non-exercise of one or more of the rights that are
rrenkert@410: specifically granted under this License. You may not convey a covered
rrenkert@410: work if you are a party to an arrangement with a third party that is
rrenkert@410: in the business of distributing software, under which you make payment
rrenkert@410: to the third party based on the extent of your activity of conveying
rrenkert@410: the work, and under which the third party grants, to any of the
rrenkert@410: parties who would receive the covered work from you, a discriminatory
rrenkert@410: patent license (a) in connection with copies of the covered work
rrenkert@410: conveyed by you (or copies made from those copies), or (b) primarily
rrenkert@410: for and in connection with specific products or compilations that
rrenkert@410: contain the covered work, unless you entered into that arrangement,
rrenkert@410: or that patent license was granted, prior to 28 March 2007.
rrenkert@410:
rrenkert@410: Nothing in this License shall be construed as excluding or limiting
rrenkert@410: any implied license or other defenses to infringement that may
rrenkert@410: otherwise be available to you under applicable patent law.
rrenkert@410:
rrenkert@410: 12. No Surrender of Others' Freedom.
rrenkert@410:
rrenkert@410: If conditions are imposed on you (whether by court order, agreement or
rrenkert@410: otherwise) that contradict the conditions of this License, they do not
rrenkert@410: excuse you from the conditions of this License. If you cannot convey a
rrenkert@410: covered work so as to satisfy simultaneously your obligations under this
rrenkert@410: License and any other pertinent obligations, then as a consequence you may
rrenkert@410: not convey it at all. For example, if you agree to terms that obligate you
rrenkert@410: to collect a royalty for further conveying from those to whom you convey
rrenkert@410: the Program, the only way you could satisfy both those terms and this
rrenkert@410: License would be to refrain entirely from conveying the Program.
rrenkert@410:
rrenkert@410: 13. Use with the GNU Affero General Public License.
rrenkert@410:
rrenkert@410: Notwithstanding any other provision of this License, you have
rrenkert@410: permission to link or combine any covered work with a work licensed
rrenkert@410: under version 3 of the GNU Affero General Public License into a single
rrenkert@410: combined work, and to convey the resulting work. The terms of this
rrenkert@410: License will continue to apply to the part which is the covered work,
rrenkert@410: but the special requirements of the GNU Affero General Public License,
rrenkert@410: section 13, concerning interaction through a network will apply to the
rrenkert@410: combination as such.
rrenkert@410:
rrenkert@410: 14. Revised Versions of this License.
rrenkert@410:
rrenkert@410: The Free Software Foundation may publish revised and/or new versions of
rrenkert@410: the GNU General Public License from time to time. Such new versions will
rrenkert@410: be similar in spirit to the present version, but may differ in detail to
rrenkert@410: address new problems or concerns.
rrenkert@410:
rrenkert@410: Each version is given a distinguishing version number. If the
rrenkert@410: Program specifies that a certain numbered version of the GNU General
rrenkert@410: Public License "or any later version" applies to it, you have the
rrenkert@410: option of following the terms and conditions either of that numbered
rrenkert@410: version or of any later version published by the Free Software
rrenkert@410: Foundation. If the Program does not specify a version number of the
rrenkert@410: GNU General Public License, you may choose any version ever published
rrenkert@410: by the Free Software Foundation.
rrenkert@410:
rrenkert@410: If the Program specifies that a proxy can decide which future
rrenkert@410: versions of the GNU General Public License can be used, that proxy's
rrenkert@410: public statement of acceptance of a version permanently authorizes you
rrenkert@410: to choose that version for the Program.
rrenkert@410:
rrenkert@410: Later license versions may give you additional or different
rrenkert@410: permissions. However, no additional obligations are imposed on any
rrenkert@410: author or copyright holder as a result of your choosing to follow a
rrenkert@410: later version.
rrenkert@410:
rrenkert@410: 15. Disclaimer of Warranty.
rrenkert@410:
rrenkert@410: THERE IS NO WARRANTY FOR THE PROGRAM, TO THE EXTENT PERMITTED BY
rrenkert@410: APPLICABLE LAW. EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT
rrenkert@410: HOLDERS AND/OR OTHER PARTIES PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY
rrenkert@410: OF ANY KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO,
rrenkert@410: THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR
rrenkert@410: PURPOSE. THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE PROGRAM
rrenkert@410: IS WITH YOU. SHOULD THE PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF
rrenkert@410: ALL NECESSARY SERVICING, REPAIR OR CORRECTION.
rrenkert@410:
rrenkert@410: 16. Limitation of Liability.
rrenkert@410:
rrenkert@410: IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
rrenkert@410: WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MODIFIES AND/OR CONVEYS
rrenkert@410: THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, INCLUDING ANY
rrenkert@410: GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING OUT OF THE
rrenkert@410: USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED TO LOSS OF
rrenkert@410: DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD
rrenkert@410: PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER PROGRAMS),
rrenkert@410: EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF
rrenkert@410: SUCH DAMAGES.
rrenkert@410:
rrenkert@410: 17. Interpretation of Sections 15 and 16.
rrenkert@410:
rrenkert@410: If the disclaimer of warranty and limitation of liability provided
rrenkert@410: above cannot be given local legal effect according to their terms,
rrenkert@410: reviewing courts shall apply local law that most closely approximates
rrenkert@410: an absolute waiver of all civil liability in connection with the
rrenkert@410: Program, unless a warranty or assumption of liability accompanies a
rrenkert@410: copy of the Program in return for a fee.
rrenkert@410:
rrenkert@410: END OF TERMS AND CONDITIONS
rrenkert@410:
rrenkert@410: How to Apply These Terms to Your New Programs
rrenkert@410:
rrenkert@410: If you develop a new program, and you want it to be of the greatest
rrenkert@410: possible use to the public, the best way to achieve this is to make it
rrenkert@410: free software which everyone can redistribute and change under these terms.
rrenkert@410:
rrenkert@410: To do so, attach the following notices to the program. It is safest
rrenkert@410: to attach them to the start of each source file to most effectively
rrenkert@410: state the exclusion of warranty; and each file should have at least
rrenkert@410: the "copyright" line and a pointer to where the full notice is found.
rrenkert@410:
rrenkert@410:
rrenkert@410: Copyright (C)
rrenkert@410:
rrenkert@410: This program is free software: you can redistribute it and/or modify
rrenkert@410: it under the terms of the GNU General Public License as published by
rrenkert@410: the Free Software Foundation, either version 3 of the License, or
rrenkert@410: (at your option) any later version.
rrenkert@410:
rrenkert@410: This program is distributed in the hope that it will be useful,
rrenkert@410: but WITHOUT ANY WARRANTY; without even the implied warranty of
rrenkert@410: MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the
rrenkert@410: GNU General Public License for more details.
rrenkert@410:
rrenkert@410: You should have received a copy of the GNU General Public License
rrenkert@410: along with this program. If not, see .
rrenkert@410:
rrenkert@410: Also add information on how to contact you by electronic and paper mail.
rrenkert@410:
rrenkert@410: If the program does terminal interaction, make it output a short
rrenkert@410: notice like this when it starts in an interactive mode:
rrenkert@410:
rrenkert@410: Copyright (C)
rrenkert@410: This program comes with ABSOLUTELY NO WARRANTY; for details type `show w'.
rrenkert@410: This is free software, and you are welcome to redistribute it
rrenkert@410: under certain conditions; type `show c' for details.
rrenkert@410:
rrenkert@410: The hypothetical commands `show w' and `show c' should show the appropriate
rrenkert@410: parts of the General Public License. Of course, your program's commands
rrenkert@410: might be different; for a GUI interface, you would use an "about box".
rrenkert@410:
rrenkert@410: You should also get your employer (if you work as a programmer) or school,
rrenkert@410: if any, to sign a "copyright disclaimer" for the program, if necessary.
rrenkert@410: For more information on this, and how to apply and follow the GNU GPL, see
rrenkert@410: .
rrenkert@410:
rrenkert@410: The GNU General Public License does not permit incorporating your program
rrenkert@410: into proprietary programs. If your program is a subroutine library, you
rrenkert@410: may consider it more useful to permit linking proprietary applications with
rrenkert@410: the library. If this is what you want to do, use the GNU Lesser General
rrenkert@410: Public License instead of this License. But first, please read
rrenkert@410: .
