msousa@261: GNU GENERAL PUBLIC LICENSE
msousa@261: Version 3, 29 June 2007
msousa@261:
msousa@261: Copyright (C) 2007 Free Software Foundation, Inc.
msousa@261: Everyone is permitted to copy and distribute verbatim copies
msousa@261: of this license document, but changing it is not allowed.
msousa@261:
msousa@261: Preamble
msousa@261:
msousa@261: The GNU General Public License is a free, copyleft license for
msousa@261: software and other kinds of works.
msousa@261:
msousa@261: The licenses for most software and other practical works are designed
msousa@261: to take away your freedom to share and change the works. By contrast,
msousa@261: the GNU General Public License is intended to guarantee your freedom to
msousa@261: share and change all versions of a program--to make sure it remains free
msousa@261: software for all its users. We, the Free Software Foundation, use the
msousa@261: GNU General Public License for most of our software; it applies also to
msousa@261: any other work released this way by its authors. You can apply it to
msousa@261: your programs, too.
msousa@261:
msousa@261: When we speak of free software, we are referring to freedom, not
msousa@261: price. Our General Public Licenses are designed to make sure that you
msousa@261: have the freedom to distribute copies of free software (and charge for
msousa@261: them if you wish), that you receive source code or can get it if you
msousa@261: want it, that you can change the software or use pieces of it in new
msousa@261: free programs, and that you know you can do these things.
msousa@261:
msousa@261: To protect your rights, we need to prevent others from denying you
msousa@261: these rights or asking you to surrender the rights. Therefore, you have
msousa@261: certain responsibilities if you distribute copies of the software, or if
msousa@261: you modify it: responsibilities to respect the freedom of others.
msousa@261:
msousa@261: For example, if you distribute copies of such a program, whether
msousa@261: gratis or for a fee, you must pass on to the recipients the same
msousa@261: freedoms that you received. You must make sure that they, too, receive
msousa@261: or can get the source code. And you must show them these terms so they
msousa@261: know their rights.
msousa@261:
msousa@261: Developers that use the GNU GPL protect your rights with two steps:
msousa@261: (1) assert copyright on the software, and (2) offer you this License
msousa@261: giving you legal permission to copy, distribute and/or modify it.
msousa@261:
msousa@261: For the developers' and authors' protection, the GPL clearly explains
msousa@261: that there is no warranty for this free software. For both users' and
msousa@261: authors' sake, the GPL requires that modified versions be marked as
msousa@261: changed, so that their problems will not be attributed erroneously to
msousa@261: authors of previous versions.
msousa@261:
msousa@261: Some devices are designed to deny users access to install or run
msousa@261: modified versions of the software inside them, although the manufacturer
msousa@261: can do so. This is fundamentally incompatible with the aim of
msousa@261: protecting users' freedom to change the software. The systematic
msousa@261: pattern of such abuse occurs in the area of products for individuals to
msousa@261: use, which is precisely where it is most unacceptable. Therefore, we
msousa@261: have designed this version of the GPL to prohibit the practice for those
msousa@261: products. If such problems arise substantially in other domains, we
msousa@261: stand ready to extend this provision to those domains in future versions
msousa@261: of the GPL, as needed to protect the freedom of users.
msousa@261:
msousa@261: Finally, every program is threatened constantly by software patents.
msousa@261: States should not allow patents to restrict development and use of
msousa@261: software on general-purpose computers, but in those that do, we wish to
msousa@261: avoid the special danger that patents applied to a free program could
msousa@261: make it effectively proprietary. To prevent this, the GPL assures that
msousa@261: patents cannot be used to render the program non-free.
msousa@261:
msousa@261: The precise terms and conditions for copying, distribution and
msousa@261: modification follow.
msousa@261:
msousa@261: TERMS AND CONDITIONS
msousa@261:
msousa@261: 0. Definitions.
msousa@261:
msousa@261: "This License" refers to version 3 of the GNU General Public License.
msousa@261:
msousa@261: "Copyright" also means copyright-like laws that apply to other kinds of
msousa@261: works, such as semiconductor masks.
msousa@261:
msousa@261: "The Program" refers to any copyrightable work licensed under this
msousa@261: License. Each licensee is addressed as "you". "Licensees" and
msousa@261: "recipients" may be individuals or organizations.
msousa@261:
msousa@261: To "modify" a work means to copy from or adapt all or part of the work
msousa@261: in a fashion requiring copyright permission, other than the making of an
msousa@261: exact copy. The resulting work is called a "modified version" of the
msousa@261: earlier work or a work "based on" the earlier work.
msousa@261:
msousa@261: A "covered work" means either the unmodified Program or a work based
msousa@261: on the Program.
msousa@261:
msousa@261: To "propagate" a work means to do anything with it that, without
msousa@261: permission, would make you directly or secondarily liable for
msousa@261: infringement under applicable copyright law, except executing it on a
msousa@261: computer or modifying a private copy. Propagation includes copying,
msousa@261: distribution (with or without modification), making available to the
msousa@261: public, and in some countries other activities as well.
msousa@261:
msousa@261: To "convey" a work means any kind of propagation that enables other
msousa@261: parties to make or receive copies. Mere interaction with a user through
msousa@261: a computer network, with no transfer of a copy, is not conveying.
msousa@261:
msousa@261: An interactive user interface displays "Appropriate Legal Notices"
msousa@261: to the extent that it includes a convenient and prominently visible
msousa@261: feature that (1) displays an appropriate copyright notice, and (2)
msousa@261: tells the user that there is no warranty for the work (except to the
msousa@261: extent that warranties are provided), that licensees may convey the
msousa@261: work under this License, and how to view a copy of this License. If
msousa@261: the interface presents a list of user commands or options, such as a
msousa@261: menu, a prominent item in the list meets this criterion.
msousa@261:
msousa@261: 1. Source Code.
msousa@261:
msousa@261: The "source code" for a work means the preferred form of the work
msousa@261: for making modifications to it. "Object code" means any non-source
msousa@261: form of a work.
msousa@261:
msousa@261: A "Standard Interface" means an interface that either is an official
msousa@261: standard defined by a recognized standards body, or, in the case of
msousa@261: interfaces specified for a particular programming language, one that
msousa@261: is widely used among developers working in that language.
msousa@261:
msousa@261: The "System Libraries" of an executable work include anything, other
msousa@261: than the work as a whole, that (a) is included in the normal form of
msousa@261: packaging a Major Component, but which is not part of that Major
msousa@261: Component, and (b) serves only to enable use of the work with that
msousa@261: Major Component, or to implement a Standard Interface for which an
msousa@261: implementation is available to the public in source code form. A
msousa@261: "Major Component", in this context, means a major essential component
msousa@261: (kernel, window system, and so on) of the specific operating system
msousa@261: (if any) on which the executable work runs, or a compiler used to
msousa@261: produce the work, or an object code interpreter used to run it.
msousa@261:
msousa@261: The "Corresponding Source" for a work in object code form means all
msousa@261: the source code needed to generate, install, and (for an executable
msousa@261: work) run the object code and to modify the work, including scripts to
msousa@261: control those activities. However, it does not include the work's
msousa@261: System Libraries, or general-purpose tools or generally available free
msousa@261: programs which are used unmodified in performing those activities but
msousa@261: which are not part of the work. For example, Corresponding Source
msousa@261: includes interface definition files associated with source files for
msousa@261: the work, and the source code for shared libraries and dynamically
msousa@261: linked subprograms that the work is specifically designed to require,
msousa@261: such as by intimate data communication or control flow between those
msousa@261: subprograms and other parts of the work.
msousa@261:
msousa@261: The Corresponding Source need not include anything that users
msousa@261: can regenerate automatically from other parts of the Corresponding
msousa@261: Source.
msousa@261:
msousa@261: The Corresponding Source for a work in source code form is that
msousa@261: same work.
msousa@261:
msousa@261: 2. Basic Permissions.
msousa@261:
msousa@261: All rights granted under this License are granted for the term of
msousa@261: copyright on the Program, and are irrevocable provided the stated
msousa@261: conditions are met. This License explicitly affirms your unlimited
msousa@261: permission to run the unmodified Program. The output from running a
msousa@261: covered work is covered by this License only if the output, given its
msousa@261: content, constitutes a covered work. This License acknowledges your
msousa@261: rights of fair use or other equivalent, as provided by copyright law.
msousa@261:
msousa@261: You may make, run and propagate covered works that you do not
msousa@261: convey, without conditions so long as your license otherwise remains
msousa@261: in force. You may convey covered works to others for the sole purpose
msousa@261: of having them make modifications exclusively for you, or provide you
msousa@261: with facilities for running those works, provided that you comply with
msousa@261: the terms of this License in conveying all material for which you do
msousa@261: not control copyright. Those thus making or running the covered works
msousa@261: for you must do so exclusively on your behalf, under your direction
msousa@261: and control, on terms that prohibit them from making any copies of
msousa@261: your copyrighted material outside their relationship with you.
msousa@261:
msousa@261: Conveying under any other circumstances is permitted solely under
msousa@261: the conditions stated below. Sublicensing is not allowed; section 10
msousa@261: makes it unnecessary.
msousa@261:
msousa@261: 3. Protecting Users' Legal Rights From Anti-Circumvention Law.
msousa@261:
msousa@261: No covered work shall be deemed part of an effective technological
msousa@261: measure under any applicable law fulfilling obligations under article
msousa@261: 11 of the WIPO copyright treaty adopted on 20 December 1996, or
msousa@261: similar laws prohibiting or restricting circumvention of such
msousa@261: measures.
msousa@261:
msousa@261: When you convey a covered work, you waive any legal power to forbid
msousa@261: circumvention of technological measures to the extent such circumvention
msousa@261: is effected by exercising rights under this License with respect to
msousa@261: the covered work, and you disclaim any intention to limit operation or
msousa@261: modification of the work as a means of enforcing, against the work's
msousa@261: users, your or third parties' legal rights to forbid circumvention of
msousa@261: technological measures.
msousa@261:
msousa@261: 4. Conveying Verbatim Copies.
msousa@261:
msousa@261: You may convey verbatim copies of the Program's source code as you
msousa@261: receive it, in any medium, provided that you conspicuously and
msousa@261: appropriately publish on each copy an appropriate copyright notice;
msousa@261: keep intact all notices stating that this License and any
msousa@261: non-permissive terms added in accord with section 7 apply to the code;
msousa@261: keep intact all notices of the absence of any warranty; and give all
msousa@261: recipients a copy of this License along with the Program.
msousa@261:
msousa@261: You may charge any price or no price for each copy that you convey,
msousa@261: and you may offer support or warranty protection for a fee.
msousa@261:
msousa@261: 5. Conveying Modified Source Versions.
msousa@261:
msousa@261: You may convey a work based on the Program, or the modifications to
msousa@261: produce it from the Program, in the form of source code under the
msousa@261: terms of section 4, provided that you also meet all of these conditions:
msousa@261:
msousa@261: a) The work must carry prominent notices stating that you modified
msousa@261: it, and giving a relevant date.
msousa@261:
msousa@261: b) The work must carry prominent notices stating that it is
msousa@261: released under this License and any conditions added under section
msousa@261: 7. This requirement modifies the requirement in section 4 to
msousa@261: "keep intact all notices".
msousa@261:
msousa@261: c) You must license the entire work, as a whole, under this
msousa@261: License to anyone who comes into possession of a copy. This
msousa@261: License will therefore apply, along with any applicable section 7
msousa@261: additional terms, to the whole of the work, and all its parts,
msousa@261: regardless of how they are packaged. This License gives no
msousa@261: permission to license the work in any other way, but it does not
msousa@261: invalidate such permission if you have separately received it.
msousa@261:
msousa@261: d) If the work has interactive user interfaces, each must display
msousa@261: Appropriate Legal Notices; however, if the Program has interactive
msousa@261: interfaces that do not display Appropriate Legal Notices, your
msousa@261: work need not make them do so.
msousa@261:
msousa@261: A compilation of a covered work with other separate and independent
msousa@261: works, which are not by their nature extensions of the covered work,
msousa@261: and which are not combined with it such as to form a larger program,
msousa@261: in or on a volume of a storage or distribution medium, is called an
msousa@261: "aggregate" if the compilation and its resulting copyright are not
msousa@261: used to limit the access or legal rights of the compilation's users
msousa@261: beyond what the individual works permit. Inclusion of a covered work
msousa@261: in an aggregate does not cause this License to apply to the other
msousa@261: parts of the aggregate.
msousa@261:
msousa@261: 6. Conveying Non-Source Forms.
msousa@261:
msousa@261: You may convey a covered work in object code form under the terms
msousa@261: of sections 4 and 5, provided that you also convey the
msousa@261: machine-readable Corresponding Source under the terms of this License,
msousa@261: in one of these ways:
msousa@261:
msousa@261: a) Convey the object code in, or embodied in, a physical product
msousa@261: (including a physical distribution medium), accompanied by the
msousa@261: Corresponding Source fixed on a durable physical medium
msousa@261: customarily used for software interchange.
msousa@261:
msousa@261: b) Convey the object code in, or embodied in, a physical product
msousa@261: (including a physical distribution medium), accompanied by a
msousa@261: written offer, valid for at least three years and valid for as
msousa@261: long as you offer spare parts or customer support for that product
msousa@261: model, to give anyone who possesses the object code either (1) a
msousa@261: copy of the Corresponding Source for all the software in the
msousa@261: product that is covered by this License, on a durable physical
msousa@261: medium customarily used for software interchange, for a price no
msousa@261: more than your reasonable cost of physically performing this
msousa@261: conveying of source, or (2) access to copy the
msousa@261: Corresponding Source from a network server at no charge.
msousa@261:
msousa@261: c) Convey individual copies of the object code with a copy of the
msousa@261: written offer to provide the Corresponding Source. This
msousa@261: alternative is allowed only occasionally and noncommercially, and
msousa@261: only if you received the object code with such an offer, in accord
msousa@261: with subsection 6b.
msousa@261:
msousa@261: d) Convey the object code by offering access from a designated
msousa@261: place (gratis or for a charge), and offer equivalent access to the
msousa@261: Corresponding Source in the same way through the same place at no
msousa@261: further charge. You need not require recipients to copy the
msousa@261: Corresponding Source along with the object code. If the place to
msousa@261: copy the object code is a network server, the Corresponding Source
msousa@261: may be on a different server (operated by you or a third party)
msousa@261: that supports equivalent copying facilities, provided you maintain
msousa@261: clear directions next to the object code saying where to find the
msousa@261: Corresponding Source. Regardless of what server hosts the
msousa@261: Corresponding Source, you remain obligated to ensure that it is
msousa@261: available for as long as needed to satisfy these requirements.
msousa@261:
msousa@261: e) Convey the object code using peer-to-peer transmission, provided
msousa@261: you inform other peers where the object code and Corresponding
msousa@261: Source of the work are being offered to the general public at no
msousa@261: charge under subsection 6d.
msousa@261:
msousa@261: A separable portion of the object code, whose source code is excluded
msousa@261: from the Corresponding Source as a System Library, need not be
msousa@261: included in conveying the object code work.
msousa@261:
msousa@261: A "User Product" is either (1) a "consumer product", which means any
msousa@261: tangible personal property which is normally used for personal, family,
msousa@261: or household purposes, or (2) anything designed or sold for incorporation
msousa@261: into a dwelling. In determining whether a product is a consumer product,
msousa@261: doubtful cases shall be resolved in favor of coverage. For a particular
msousa@261: product received by a particular user, "normally used" refers to a
msousa@261: typical or common use of that class of product, regardless of the status
msousa@261: of the particular user or of the way in which the particular user
msousa@261: actually uses, or expects or is expected to use, the product. A product
msousa@261: is a consumer product regardless of whether the product has substantial
msousa@261: commercial, industrial or non-consumer uses, unless such uses represent
msousa@261: the only significant mode of use of the product.
msousa@261:
msousa@261: "Installation Information" for a User Product means any methods,
msousa@261: procedures, authorization keys, or other information required to install
msousa@261: and execute modified versions of a covered work in that User Product from
msousa@261: a modified version of its Corresponding Source. The information must
msousa@261: suffice to ensure that the continued functioning of the modified object
msousa@261: code is in no case prevented or interfered with solely because
msousa@261: modification has been made.
msousa@261:
msousa@261: If you convey an object code work under this section in, or with, or
msousa@261: specifically for use in, a User Product, and the conveying occurs as
msousa@261: part of a transaction in which the right of possession and use of the
msousa@261: User Product is transferred to the recipient in perpetuity or for a
msousa@261: fixed term (regardless of how the transaction is characterized), the
msousa@261: Corresponding Source conveyed under this section must be accompanied
msousa@261: by the Installation Information. But this requirement does not apply
msousa@261: if neither you nor any third party retains the ability to install
msousa@261: modified object code on the User Product (for example, the work has
msousa@261: been installed in ROM).
msousa@261:
msousa@261: The requirement to provide Installation Information does not include a
msousa@261: requirement to continue to provide support service, warranty, or updates
msousa@261: for a work that has been modified or installed by the recipient, or for
msousa@261: the User Product in which it has been modified or installed. Access to a
msousa@261: network may be denied when the modification itself materially and
msousa@261: adversely affects the operation of the network or violates the rules and
msousa@261: protocols for communication across the network.
msousa@261:
msousa@261: Corresponding Source conveyed, and Installation Information provided,
msousa@261: in accord with this section must be in a format that is publicly
msousa@261: documented (and with an implementation available to the public in
msousa@261: source code form), and must require no special password or key for
msousa@261: unpacking, reading or copying.
msousa@261:
msousa@261: 7. Additional Terms.
msousa@261:
msousa@261: "Additional permissions" are terms that supplement the terms of this
msousa@261: License by making exceptions from one or more of its conditions.
msousa@261: Additional permissions that are applicable to the entire Program shall
msousa@261: be treated as though they were included in this License, to the extent
msousa@261: that they are valid under applicable law. If additional permissions
msousa@261: apply only to part of the Program, that part may be used separately
msousa@261: under those permissions, but the entire Program remains governed by
msousa@261: this License without regard to the additional permissions.
msousa@261:
msousa@261: When you convey a copy of a covered work, you may at your option
msousa@261: remove any additional permissions from that copy, or from any part of
msousa@261: it. (Additional permissions may be written to require their own
msousa@261: removal in certain cases when you modify the work.) You may place
msousa@261: additional permissions on material, added by you to a covered work,
msousa@261: for which you have or can give appropriate copyright permission.
msousa@261:
msousa@261: Notwithstanding any other provision of this License, for material you
msousa@261: add to a covered work, you may (if authorized by the copyright holders of
msousa@261: that material) supplement the terms of this License with terms:
msousa@261:
msousa@261: a) Disclaiming warranty or limiting liability differently from the
msousa@261: terms of sections 15 and 16 of this License; or
msousa@261:
msousa@261: b) Requiring preservation of specified reasonable legal notices or
msousa@261: author attributions in that material or in the Appropriate Legal
msousa@261: Notices displayed by works containing it; or
msousa@261:
msousa@261: c) Prohibiting misrepresentation of the origin of that material, or
msousa@261: requiring that modified versions of such material be marked in
msousa@261: reasonable ways as different from the original version; or
msousa@261:
msousa@261: d) Limiting the use for publicity purposes of names of licensors or
msousa@261: authors of the material; or
msousa@261:
msousa@261: e) Declining to grant rights under trademark law for use of some
msousa@261: trade names, trademarks, or service marks; or
msousa@261:
msousa@261: f) Requiring indemnification of licensors and authors of that
msousa@261: material by anyone who conveys the material (or modified versions of
msousa@261: it) with contractual assumptions of liability to the recipient, for
msousa@261: any liability that these contractual assumptions directly impose on
msousa@261: those licensors and authors.
msousa@261:
msousa@261: All other non-permissive additional terms are considered "further
msousa@261: restrictions" within the meaning of section 10. If the Program as you
msousa@261: received it, or any part of it, contains a notice stating that it is
msousa@261: governed by this License along with a term that is a further
msousa@261: restriction, you may remove that term. If a license document contains
msousa@261: a further restriction but permits relicensing or conveying under this
msousa@261: License, you may add to a covered work material governed by the terms
msousa@261: of that license document, provided that the further restriction does
msousa@261: not survive such relicensing or conveying.
msousa@261:
msousa@261: If you add terms to a covered work in accord with this section, you
msousa@261: must place, in the relevant source files, a statement of the
msousa@261: additional terms that apply to those files, or a notice indicating
msousa@261: where to find the applicable terms.
msousa@261:
msousa@261: Additional terms, permissive or non-permissive, may be stated in the
msousa@261: form of a separately written license, or stated as exceptions;
msousa@261: the above requirements apply either way.
msousa@261:
msousa@261: 8. Termination.
msousa@261:
msousa@261: You may not propagate or modify a covered work except as expressly
msousa@261: provided under this License. Any attempt otherwise to propagate or
msousa@261: modify it is void, and will automatically terminate your rights under
msousa@261: this License (including any patent licenses granted under the third
msousa@261: paragraph of section 11).
msousa@261:
msousa@261: However, if you cease all violation of this License, then your
msousa@261: license from a particular copyright holder is reinstated (a)
msousa@261: provisionally, unless and until the copyright holder explicitly and
msousa@261: finally terminates your license, and (b) permanently, if the copyright
msousa@261: holder fails to notify you of the violation by some reasonable means
msousa@261: prior to 60 days after the cessation.
msousa@261:
msousa@261: Moreover, your license from a particular copyright holder is
msousa@261: reinstated permanently if the copyright holder notifies you of the
msousa@261: violation by some reasonable means, this is the first time you have
msousa@261: received notice of violation of this License (for any work) from that
msousa@261: copyright holder, and you cure the violation prior to 30 days after
msousa@261: your receipt of the notice.
msousa@261:
msousa@261: Termination of your rights under this section does not terminate the
msousa@261: licenses of parties who have received copies or rights from you under
msousa@261: this License. If your rights have been terminated and not permanently
msousa@261: reinstated, you do not qualify to receive new licenses for the same
msousa@261: material under section 10.
msousa@261:
msousa@261: 9. Acceptance Not Required for Having Copies.
msousa@261:
msousa@261: You are not required to accept this License in order to receive or
msousa@261: run a copy of the Program. Ancillary propagation of a covered work
msousa@261: occurring solely as a consequence of using peer-to-peer transmission
msousa@261: to receive a copy likewise does not require acceptance. However,
msousa@261: nothing other than this License grants you permission to propagate or
msousa@261: modify any covered work. These actions infringe copyright if you do
msousa@261: not accept this License. Therefore, by modifying or propagating a
msousa@261: covered work, you indicate your acceptance of this License to do so.
msousa@261:
msousa@261: 10. Automatic Licensing of Downstream Recipients.
msousa@261:
msousa@261: Each time you convey a covered work, the recipient automatically
msousa@261: receives a license from the original licensors, to run, modify and
msousa@261: propagate that work, subject to this License. You are not responsible
msousa@261: for enforcing compliance by third parties with this License.
msousa@261:
msousa@261: An "entity transaction" is a transaction transferring control of an
msousa@261: organization, or substantially all assets of one, or subdividing an
msousa@261: organization, or merging organizations. If propagation of a covered
msousa@261: work results from an entity transaction, each party to that
msousa@261: transaction who receives a copy of the work also receives whatever
msousa@261: licenses to the work the party's predecessor in interest had or could
msousa@261: give under the previous paragraph, plus a right to possession of the
msousa@261: Corresponding Source of the work from the predecessor in interest, if
msousa@261: the predecessor has it or can get it with reasonable efforts.
msousa@261:
msousa@261: You may not impose any further restrictions on the exercise of the
msousa@261: rights granted or affirmed under this License. For example, you may
msousa@261: not impose a license fee, royalty, or other charge for exercise of
msousa@261: rights granted under this License, and you may not initiate litigation
msousa@261: (including a cross-claim or counterclaim in a lawsuit) alleging that
msousa@261: any patent claim is infringed by making, using, selling, offering for
msousa@261: sale, or importing the Program or any portion of it.
msousa@261:
msousa@261: 11. Patents.
msousa@261:
msousa@261: A "contributor" is a copyright holder who authorizes use under this
msousa@261: License of the Program or a work on which the Program is based. The
msousa@261: work thus licensed is called the contributor's "contributor version".
msousa@261:
msousa@261: A contributor's "essential patent claims" are all patent claims
msousa@261: owned or controlled by the contributor, whether already acquired or
msousa@261: hereafter acquired, that would be infringed by some manner, permitted
msousa@261: by this License, of making, using, or selling its contributor version,
msousa@261: but do not include claims that would be infringed only as a
msousa@261: consequence of further modification of the contributor version. For
msousa@261: purposes of this definition, "control" includes the right to grant
msousa@261: patent sublicenses in a manner consistent with the requirements of
msousa@261: this License.
msousa@261:
msousa@261: Each contributor grants you a non-exclusive, worldwide, royalty-free
msousa@261: patent license under the contributor's essential patent claims, to
msousa@261: make, use, sell, offer for sale, import and otherwise run, modify and
msousa@261: propagate the contents of its contributor version.
msousa@261:
msousa@261: In the following three paragraphs, a "patent license" is any express
msousa@261: agreement or commitment, however denominated, not to enforce a patent
msousa@261: (such as an express permission to practice a patent or covenant not to
msousa@261: sue for patent infringement). To "grant" such a patent license to a
msousa@261: party means to make such an agreement or commitment not to enforce a
msousa@261: patent against the party.
msousa@261:
msousa@261: If you convey a covered work, knowingly relying on a patent license,
msousa@261: and the Corresponding Source of the work is not available for anyone
msousa@261: to copy, free of charge and under the terms of this License, through a
msousa@261: publicly available network server or other readily accessible means,
msousa@261: then you must either (1) cause the Corresponding Source to be so
msousa@261: available, or (2) arrange to deprive yourself of the benefit of the
msousa@261: patent license for this particular work, or (3) arrange, in a manner
msousa@261: consistent with the requirements of this License, to extend the patent
msousa@261: license to downstream recipients. "Knowingly relying" means you have
msousa@261: actual knowledge that, but for the patent license, your conveying the
msousa@261: covered work in a country, or your recipient's use of the covered work
msousa@261: in a country, would infringe one or more identifiable patents in that
msousa@261: country that you have reason to believe are valid.
msousa@261:
msousa@261: If, pursuant to or in connection with a single transaction or
msousa@261: arrangement, you convey, or propagate by procuring conveyance of, a
msousa@261: covered work, and grant a patent license to some of the parties
msousa@261: receiving the covered work authorizing them to use, propagate, modify
msousa@261: or convey a specific copy of the covered work, then the patent license
msousa@261: you grant is automatically extended to all recipients of the covered
msousa@261: work and works based on it.
msousa@261:
msousa@261: A patent license is "discriminatory" if it does not include within
msousa@261: the scope of its coverage, prohibits the exercise of, or is
msousa@261: conditioned on the non-exercise of one or more of the rights that are
msousa@261: specifically granted under this License. You may not convey a covered
msousa@261: work if you are a party to an arrangement with a third party that is
msousa@261: in the business of distributing software, under which you make payment
msousa@261: to the third party based on the extent of your activity of conveying
msousa@261: the work, and under which the third party grants, to any of the
msousa@261: parties who would receive the covered work from you, a discriminatory
msousa@261: patent license (a) in connection with copies of the covered work
msousa@261: conveyed by you (or copies made from those copies), or (b) primarily
msousa@261: for and in connection with specific products or compilations that
msousa@261: contain the covered work, unless you entered into that arrangement,
msousa@261: or that patent license was granted, prior to 28 March 2007.
msousa@261:
msousa@261: Nothing in this License shall be construed as excluding or limiting
msousa@261: any implied license or other defenses to infringement that may
msousa@261: otherwise be available to you under applicable patent law.
msousa@261:
msousa@261: 12. No Surrender of Others' Freedom.
msousa@261:
msousa@261: If conditions are imposed on you (whether by court order, agreement or
msousa@261: otherwise) that contradict the conditions of this License, they do not
msousa@261: excuse you from the conditions of this License. If you cannot convey a
msousa@261: covered work so as to satisfy simultaneously your obligations under this
msousa@261: License and any other pertinent obligations, then as a consequence you may
msousa@261: not convey it at all. For example, if you agree to terms that obligate you
msousa@261: to collect a royalty for further conveying from those to whom you convey
msousa@261: the Program, the only way you could satisfy both those terms and this
msousa@261: License would be to refrain entirely from conveying the Program.
msousa@261:
msousa@261: 13. Use with the GNU Affero General Public License.
msousa@261:
msousa@261: Notwithstanding any other provision of this License, you have
msousa@261: permission to link or combine any covered work with a work licensed
msousa@261: under version 3 of the GNU Affero General Public License into a single
msousa@261: combined work, and to convey the resulting work. The terms of this
msousa@261: License will continue to apply to the part which is the covered work,
msousa@261: but the special requirements of the GNU Affero General Public License,
msousa@261: section 13, concerning interaction through a network will apply to the
msousa@261: combination as such.
msousa@261:
msousa@261: 14. Revised Versions of this License.
msousa@261:
msousa@261: The Free Software Foundation may publish revised and/or new versions of
msousa@261: the GNU General Public License from time to time. Such new versions will
msousa@261: be similar in spirit to the present version, but may differ in detail to
msousa@261: address new problems or concerns.
msousa@261:
msousa@261: Each version is given a distinguishing version number. If the
msousa@261: Program specifies that a certain numbered version of the GNU General
msousa@261: Public License "or any later version" applies to it, you have the
msousa@261: option of following the terms and conditions either of that numbered
msousa@261: version or of any later version published by the Free Software
msousa@261: Foundation. If the Program does not specify a version number of the
msousa@261: GNU General Public License, you may choose any version ever published
msousa@261: by the Free Software Foundation.
msousa@261:
msousa@261: If the Program specifies that a proxy can decide which future
msousa@261: versions of the GNU General Public License can be used, that proxy's
msousa@261: public statement of acceptance of a version permanently authorizes you
msousa@261: to choose that version for the Program.
msousa@261:
msousa@261: Later license versions may give you additional or different
msousa@261: permissions. However, no additional obligations are imposed on any
msousa@261: author or copyright holder as a result of your choosing to follow a
msousa@261: later version.
msousa@261:
msousa@261: 15. Disclaimer of Warranty.
msousa@261:
msousa@261: THERE IS NO WARRANTY FOR THE PROGRAM, TO THE EXTENT PERMITTED BY
msousa@261: APPLICABLE LAW. EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT
msousa@261: HOLDERS AND/OR OTHER PARTIES PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY
msousa@261: OF ANY KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO,
msousa@261: THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR
msousa@261: PURPOSE. THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE PROGRAM
msousa@261: IS WITH YOU. SHOULD THE PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF
msousa@261: ALL NECESSARY SERVICING, REPAIR OR CORRECTION.
msousa@261:
msousa@261: 16. Limitation of Liability.
msousa@261:
msousa@261: IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
msousa@261: WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MODIFIES AND/OR CONVEYS
msousa@261: THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, INCLUDING ANY
msousa@261: GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING OUT OF THE
msousa@261: USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED TO LOSS OF
msousa@261: DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD
msousa@261: PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER PROGRAMS),
msousa@261: EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF
msousa@261: SUCH DAMAGES.
msousa@261:
msousa@261: 17. Interpretation of Sections 15 and 16.
msousa@261:
msousa@261: If the disclaimer of warranty and limitation of liability provided
msousa@261: above cannot be given local legal effect according to their terms,
msousa@261: reviewing courts shall apply local law that most closely approximates
msousa@261: an absolute waiver of all civil liability in connection with the
msousa@261: Program, unless a warranty or assumption of liability accompanies a
msousa@261: copy of the Program in return for a fee.
msousa@261:
msousa@261: END OF TERMS AND CONDITIONS
msousa@261:
msousa@261: How to Apply These Terms to Your New Programs
msousa@261:
msousa@261: If you develop a new program, and you want it to be of the greatest
msousa@261: possible use to the public, the best way to achieve this is to make it
msousa@261: free software which everyone can redistribute and change under these terms.
msousa@261:
msousa@261: To do so, attach the following notices to the program. It is safest
msousa@261: to attach them to the start of each source file to most effectively
msousa@261: state the exclusion of warranty; and each file should have at least
msousa@261: the "copyright" line and a pointer to where the full notice is found.
msousa@261:
msousa@261:
msousa@261: Copyright (C)
msousa@261:
msousa@261: This program is free software: you can redistribute it and/or modify
msousa@261: it under the terms of the GNU General Public License as published by
msousa@261: the Free Software Foundation, either version 3 of the License, or
msousa@261: (at your option) any later version.
msousa@261:
msousa@261: This program is distributed in the hope that it will be useful,
msousa@261: but WITHOUT ANY WARRANTY; without even the implied warranty of
msousa@261: MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the
msousa@261: GNU General Public License for more details.
msousa@261:
msousa@261: You should have received a copy of the GNU General Public License
msousa@261: along with this program. If not, see .
msousa@261:
msousa@261: Also add information on how to contact you by electronic and paper mail.
msousa@261:
msousa@261: If the program does terminal interaction, make it output a short
msousa@261: notice like this when it starts in an interactive mode:
msousa@261:
msousa@261: Copyright (C)
msousa@261: This program comes with ABSOLUTELY NO WARRANTY; for details type `show w'.
msousa@261: This is free software, and you are welcome to redistribute it
msousa@261: under certain conditions; type `show c' for details.
msousa@261:
msousa@261: The hypothetical commands `show w' and `show c' should show the appropriate
msousa@261: parts of the General Public License. Of course, your program's commands
msousa@261: might be different; for a GUI interface, you would use an "about box".
msousa@261:
msousa@261: You should also get your employer (if you work as a programmer) or school,
msousa@261: if any, to sign a "copyright disclaimer" for the program, if necessary.
msousa@261: For more information on this, and how to apply and follow the GNU GPL, see
msousa@261: .
msousa@261:
msousa@261: The GNU General Public License does not permit incorporating your program
msousa@261: into proprietary programs. If your program is a subroutine library, you
msousa@261: may consider it more useful to permit linking proprietary applications with
msousa@261: the library. If this is what you want to do, use the GNU Lesser General
msousa@261: Public License instead of this License. But first, please read
msousa@261: .
